How to distinguish between electronic parking brake and automatic parking?

1. The electronic handbrake needs to be opened manually, and the automatic parking does not need to manually press the button;

2. The electronic handbrake has changed from the pull handle of the mechanical handbrake to a button, and automatic parking is an extended function of the electronic handbrake;

3. The electronic parking brake is used for daily parking, and the automatic parking is suitable for use in urban road conditions;

4. The electronic handbrake is a technology that realizes the parking brake by electronic control, which controls the parking brake through the friction generated by the brake disc and the brake pads, and the automatic parking belongs to a function in the braking system, which will automatically pull the handbrake to ensure safety after the vehicle stops, and the handbrake effect will be automatically lifted when the accelerator is lightly stepped on.

Look at the brakes. The electronic parking brake needs to be operated manually, while the automatic brake does not have this function.

The control principle of automatic parking is different from that of electronic handbrake, automatic parking is to maintain the vehicle braking by controlling the braking system, and the electronic parking brake is to use the electronic structure to replace the traditional handbrake device to realize the role of parking brake.

Electronic parking brake is a technology that realizes parking brake by electronic control. To put it simply, it is to replace the former handbrake lever with the form of an electronic button.

Auto Parking is a function that automatically pulls the handbrake on your behalf, which is especially suitable for ramp parking and frequent stops and starts.

The difference between an electronic parking brake and an automatic parking car.

1. The electronic handbrake needs to be opened manually, and the automatic parking does not need to manually press the button;

2. The electronic handbrake has changed from the pull handle of the mechanical handbrake to a button, and automatic parking is an extended function of the electronic handbrake;

3. The electronic parking brake is used for daily parking, and the automatic parking is suitable for use in urban road conditions;

4. The electronic handbrake is a technology that realizes the parking brake by electronic control, which controls the parking brake through the friction generated by the brake disc and the brake pads, and the automatic parking belongs to a function in the braking system, which will automatically pull the handbrake to ensure safety after the vehicle stops, and the handbrake effect will be automatically lifted when the accelerator is lightly stepped on.

To put it simply, automatic parking is a temporary parking while driving, to prevent the vehicle from slipping, is a function that automatically pulls the handbrake for you, such as when the traffic is jammed, when parking and waiting for traffic lights, when parking uphill and downhill, you don't need to pull the handbrake, so that we can effectively prevent the vehicle from slipping when we stop temporarily, and at the same time, when the vehicle starts, the automatic parking system is automatically lifted, safe and efficient. auto

Hold automatic parking is an extended function of ESP, which is controlled by ESP components, and the brake management system controls the four-wheel brake through the extended function of ESP. The inscription (a) in the figure below is automatic parking.

The electronic handbrake is actually a handbrake, but the handle of the original mechanical handbrake has become an electronic button, which needs to be started manually. The parking brake is controlled by the friction generated by the brake disc and the brake pads. And the icon display is obviously different, the following figure (p) is the electronic parking brake.

Ladies and gentlemen, don't confuse the electronic parking brake with automatic parking, otherwise there is no need to put two things with the same function in the same car, right?

Auto parking, its buttons are often written on the auto

Hold or a big A. It is equivalent to an automatic handbrake, which can then be parked without turning off the vehicle when parked. If you encounter a red light while driving on the road, you press the brakes to stop the car, and then it will work automatically, even if you release the brakes, it will automatically keep the car at a standstill.

When you press the gas pedal when the green light comes on, it will automatically unlock and the car will move forward. This has two advantages, the first is that you don't have to constantly press the brakes when parking, and the second is that you don't have to worry about slipping on the ramp.

The electronic handbrake is often represented by a capital letter P, and the biggest difference between it and the traditional handbrake is that it saves space and turns the previous mechanical cable structure into an electronic structure, but you still need to operate it manually. In contrast, automatic parking is a bit more advanced and intelligent than the electronic parking brake. The biggest difference between the two is that one is automatic, while the other requires you to do it manually.

The difference between an electronic parking brake and an automatic parking car.

When the vehicle is powered on to get started, press the automatic parking button behind the electronic handbrake, the light is on behalf of the function is on, when the vehicle steps on the brake, the electronic handbrake will work automatically, release the brake, and the vehicle will not slip, which is very safe.

The main function of automatic parking is to keep the vehicle in a braking state without turning off the ignition when the vehicle is stopped. When the accelerator pedal is lightly pressed, the brake state is released. Manual transmission models also need to press the accelerator lightly to release, and the clutch cannot be lifted only to release the parking state.

To put it simply, it will automatically pull the handbrake for you and automatically help you remove it.

Advantages of automatic parking.

1. In case of traffic lights and other situations that require a short stop, the system will automatically brake the wheels after the vehicle is stopped to prevent rolling.

2. When starting uphill, the system will automatically brake to prevent skidding, and the system will automatically release the wheels and move forward directly after starting.

3. The parking lock does not need to pull the handbrake, and the system will automatically brake the wheels at this time, but it is only available in some models.

Here's how:

1. First of all, the electronic handbrake, as the name suggests, the effect of the electronic handbrake and the mechanical handbrake is the same, as long as the electronic handbrake is toggled up, the car will park.

2. For general automatic transmission models, after pulling up the electronic parking brake, as long as you step on the accelerator to start, the car will automatically release the electronic parking brake. Of course, you can also press down on the button of the electronic parking brake to release the electronic parking brake.

3. Now let's take a look at automatic parking, the names of many models are different, for example, many models are called atuo hold, of course, this varies from car to car. The function of this is to help you step on the brake, this button, generally near the electronic parking brake.

4. So what function does it achieve, as long as you press this button, after you step on the brake and stop the car for more than two seconds, the automatic parking function will automatically help you step on the brake. At this time, you will find that the brake pedal can not bounce back when you press it, and the same as the electronic parking brake, as long as you step on the accelerator to dismiss the automatic parking, the car will automatically help you remove the electronic parking.

Application of the electronic parking brake system.

The working principle of the electronic parking system is the same as that of the manual mechanical parking brake system, and the parking is realized by the friction clamping between the brake shoe and the brake wheel hub or the friction pad and the brake disc, but the control mode is replaced by the original manual operation and mechanical linkage by electronic pressing and motor action, so the system is called the electronically controlled mechanical parking brake system.

At present, there are two main forms of electronic parking brake technology applied in automobiles, one is the cable-type electronic parking brake system, and the other is the caliper-integrated electronic parking brake system.

Because the cable-based electronic parking brake system retains the cable of the traditional mechanical parking brake system, it is only a transitional product for early application, and it is less widely used in automobiles. The system replaces traditional controls such as parking brake handles, mechanical levers, and cables with electronic buttons and motor components.

The motor assembly is integrated into the left and right rear brake calipers, and the electronic control unit (ECU) and the motor assembly are connected directly via an electrical wiring harness. When parking, when the driver operates the electronic buttons of the electronic parking brake system, the electronic control unit will control the action of the electric motor integrated in the left and right brake calipers, and drive the piston of the brake caliper to move to generate mechanical clamping force to complete the parking.

Usage of the electronic parking brake.

There are two kinds of electronic handbrakes on the market, one is a pure switch type of electronic handbrake, press a button, the vehicle handbrake is brought up, and then press the button to release the handbrake.

The other is similar to the glass lifting button, the button is hooked up to work with the handbrake, and the button is pressed down to release the handbrake, and most of the cars with electronic handbrakes can be automatically lifted without manually lifting the handbrake as long as the accelerator is lightly pressed.

Usage of automatic parking.

Automatic parking and electronic parking brake are used together, generally the automatic parking button is next to the electronic parking brake (but not vehicles with electronic parking brake have automatic parking), as long as the automatic parking is lit and the brake is stepped on, a letter will be lit on the screen.

At this time, the car has been braked, even if the vehicle will not run even if the foot brake is released, to prevent the phenomenon of slipping, when ready to start, directly step on the accelerator, automatically lift the automatic parking, and the automatic parking at the advanced point will be automatically brought to the electronic parking after the car is turned off, release the seat belt, open the door, and automatically bring the electronic parking brake.

Electronic parking brake.

Electronic parking brake is a technology that realizes parking brake by electronic control. Its working principle is the same as that of the mechanical handbrake, which is to control the parking brake through the friction generated by the brake disc and the brake pads, but the control mode has changed from the previous mechanical handbrake lever to an electronic button.

How to use: When we want to stop for a long time, after pressing the brake pedal to make the vehicle stationary, pull up the electronic button "P", then the electronic handbrake starts, and the braking state of the vehicle is the same as pulling the mechanical handbrake before. When we need to disable the electronic parking brake function, we just need to press the brake pedal and press the button down. In addition, you can also put the gear into D gear and press the accelerator, at which point the system will also brake and release.

Automatic parking. The Auto Hold function is an extension of the Vehicle Stability Control (ESP) system, which eliminates the need for long periods of time when the vehicle is stopped, and prevents the vehicle from coasting unnecessarily when the automatic electronic parking brake is activated.

How to use: In case of a short stop at a traffic light, press the auto-parking function button, and the system will automatically brake the wheels after the vehicle has stopped to prevent rolling. The automatic parking function is automatically deactivated when the driver presses the accelerator pedal, pulls out the seat belt buckle, or opens the door. Therefore, if you need to get out of the car or unbuckle the seat belt during the braking of the vehicle, you must be in the P gear or turn on the electronic parking brake function.

The function effect is the same but the use is different, the "electronic handbrake" (generally used when you plan to turn off the engine and stop), and the ordinary handbrake has the same effect. "Auto-parking" means that the driver does not need to brake for a long time when the vehicle is stopped. And when the automatic electronic parking brake is activated, it can avoid unnecessary sliding of the vehicle, simply put, the vehicle will not slip behind.

These are two completely different system configurations, the electronic parking brake is a manual parking system, automatic parking, which means that the commander can automatically park according to the driving computer.

There is no direct relationship between the two. Automatic parking is a parking function, while electronic parking brake is a braking function.

The latter is an overview of the content of the control program based on the former: the function and value of the electronic parking brake, and the concept and function of automatic parking. [P+Autohold] is one of the most common configurations in automatic transmission vehicles, namely electronic parking brake and automatic parking.

The two buttons are always laid out side by side, so what is the difference between the functions of the two programs, or why is parking split into two buttons?

Electronic parking brake. Parking is defined as parking. The parking of a manual transmission car is carried out by a "handbrake lever". After lifting, lock the rear wheel and release the brakes. There are two systems in the automatic transmission car, one is the basic handbrake and the other is the ratchet pawl parking structure of the transmission's P gear.

This article discusses the handbrake for automatic transmission cars. The so-called electronic handbrake refers to the control program triggered by the button, and the electronic control unit controls the motor to tighten or loosen the cable to realize the brake control after the rear wheel is turned off. So, the purpose of replacing the manipulator brake with "button + electronic control + motor" is purely for the sake of labor saving or beauty?

Standard answer: The design of the electronic handbrake can reduce the occupation of the armrest area by the lever, and it can indeed make the center control area more beautiful. But that's not the core value of the system!

First of all, the important value is to improve the safety level of "forced handbrake deceleration". You should know that ordinary mechanical brakes can only brake the rear wheels, and pulling up and locking at high speed is likely to cause the vehicle to lose tail flick control, while electronic parking brakes will not.

The electronic parking brake also brakes the rear wheels only when the vehicle is parked normally, but after lifting the button firmly for 2 3 seconds while driving, the control system activates the electrical signal and transmits it to the ECU, which then controls the ESP body stability program to brake the vehicle in all directions!

Moreover, the ESP monitors and adjusts the body attitude when decelerating, which can be achieved by adjusting the braking force of one wheel or the braking force of the front and rear wheels to decelerate with maximum force but ensure that the vehicle does not lose control. This kind of safe forced deceleration is not achievable with mechanical braking, so this system is very valuable.

The automatic parking electronic parking brake is a "hand control program" controlled by pressing a button, and the automatic parking is an automatic control program with "Li Xiang memory function".

Assuming that the button is manually turned on and off after the engine is turned off, only a car with a [P button] can pull up or release the handbrake. But if there is a "P+ Auto Hold" button, as long as the program is set and the P gear is turned on, the operation of the vehicle will become very simple and safe.

For example, the electronic parking brake will automatically pull up when the P gear is engaged, which can prevent the impact on the transmission structure caused by only the ratchet pawls when parking. Or it can turn off normally during automatic start-stop and stop-off operation, and the system can also automatically brake to prevent the car from skidding. Some vehicles can activate the system after opening the door.

Is it much more secure?

Summary: The electronic handbrake is a safety configuration that involves more ESP involvement than mechanical braking when braking is forced. Automatic parking is the difference between Duanshou to further improve safety on the basis of safety configuration, and at the same time simplify operation to make the car experience more ideal.
