What is an automotive ESP? What does automotive ESP mean

Electronic BAI Stability System (ESP) is a general term for a system or program designed to improve the vehicle's handling performance while effectively preventing the car from getting out of control when it reaches its dynamic limit. The electronic stability program improves vehicle safety and handling.

The ESP includes the ABS anti-lock braking system and the ASR anti-slip system, which are an extension of the functions of these two systems.

The ESP system consists of a control unit and steering sensors (to monitor the steering angle of the steering wheel), wheel sensors (to monitor the speed rotation of each wheel), a side slip sensor (to monitor the rotation of the vehicle body around the vertical axis), and a lateral acceleration sensor (to monitor the centrifugal force when the car is turning). The control unit judges the operating status of the vehicle through the signals of these sensors, and then issues control commands.

Extended Material: Components of an ESP.

1. Sensors: steering sensors, wheel sensors, side slip sensors, lateral acceleration sensors, steering wheel accelerator brake pedal sensors, etc. These sensors are responsible for collecting data on the state of the car body.

2. ESP computer: calculate the data collected by the sensor, calculate the body status and then compare it with the pre-set data in the memory. When the computer calculates the data beyond the value stored in the memory, that is, the body is close to losing control or has lost control, the actuator is ordered to work to ensure that the driving state of the body can meet the driver's intention as much as possible.

3. Actuator: The actuator of ESP is the braking system of 4 wheels, in fact, ESP is to help the driver step on the brakes. Unlike cars without ESP, cars equipped with ESP have a brake system that accumulates pressure.

To put it simply, the computer can add the brake oil pipe of a certain wheel for the driver when the driver does not apply the brakes as needed.

When the vehicle has a tendency to flick, the ESP brakes the other wheel to weaken the rotation. This helps the vehicle to comply with the driver's steering intent.

It is the electronic stability system of the body, which is a system that stabilizes the body when cornering and does not slip sideways.

Many cars have ESP as a function, so what is this function for? Novice friends should never turn it off at will.

Hello subject, ESP is the car stability system, ESP calculates the data collected by the sensor, calculates the body status and then compares it with the pre-set data in the memory. When the computer calculates the data beyond the value stored in the memory, that is, the body is close to losing control or has lost control, the command is executed.

1. Substance: The body stability system is essentially an active safety configuration, which can improve the safety and handling of the car and ensure the safety of the car and its occupants in the process of driving the car.

2. Function: The body stability system equipped with the car can greatly improve the handling and safety of the car, in the process of driving the car, when the car has a sharp turn and rapid acceleration, the sensor on the car can quickly perceive and take corresponding measures to control the tires of the car accordingly, reduce the wheel sliding, and also reduce the power output of the engine to ensure the stability of the body.

The Importance of ESP:

The ESP system in the car is extremely important for the car, it can greatly improve the handling performance of the car, especially for the SUV model with a high chassis. However, the ESP system is also divided into levels and versions, with two types of two-channel control and four-channel control. Generally, the ESP system equipped on low-end models is a lower version, which uses more two-channel control and has relatively poor performance.

In practice, the performance of the ESP system is usually judged by the results of the elk experiment. Generally, the higher the speed of the elk test, the better the handling of the car, the less likely the car is to lose control, and the safer it is.

ESP is the abbreviation of English ElectronicsTabilityProgram, which is translated into Chinese as "Electronic Stability Program". This group of systems usually supports ABS and ASR (Drive Anti-Skid System, also known as Traction Control System). It analyzes the driving status information from each sensor and then sends a correction command to ABS and ASR to help the vehicle maintain dynamic balance.

ESP provides optimal stability in all conditions, especially in oversteer or understeer situations.

ESPs generally need to install steering sensors, wheel sensors, side slip sensors, lateral acceleration sensors, etc. The ESP can monitor the car's driving status and automatically apply braking force to one or more wheels to keep the car running in the normal lane, and in some cases can even apply braking up to 150 times per second. There are currently 3 types of ESPs:

a four-channel or four-wheel system capable of applying braking force to four wheels independently; a two-channel system that can apply braking force to both front wheels independently; This is a three-channel system that applies braking force to both front wheels independently and simultaneously to the rear wheels.

The most important feature of ESP is its proactive nature, if ABS is a reactive response, then ESP can prevent problems before they occur.

ESP is the general name for the electronic stability control system of the body, which is a system or program designed to improve the handling performance of the vehicle while effectively preventing the car from losing control when it reaches its dynamic limit. The electronic stability program improves overall vehicle safety and handling. When the ESP system works or fails, the fault light will be notified to prompt in the instrument cluster.

<><What does automotive ESP mean

Now many people buy a car are more concerned about the safety of the car, hope that the more safety configuration on the car, the better, now the more common car safety configuration has, brake force distribution, brake assist, traction control, and some more advanced merging assistance, lane departure, etc., today to talk about the car ESP system, so what does the car ESP mean and how to use the car ESP system.

The Chinese name of ESP is body electronic stability system.

That is, when the vehicle passes over a road surface with less friction, the direction and speed of the vehicle cannot be controlled by the driver due to tire skidding, and the ESP can help the driver regain control of the vehicle by braking the wheels that are not slipping. This means that the ESP will control the brakes of the front wheel on one side, and will brake the left front wheel when it oversteers to the right, and brake the right front wheel when it oversteers to the left. In short, ESP ensures that the vehicle is stable and does not let the car lose control.

So when does an ESP need to be shut down?

The adhesion on the opposite side of the wheel is small, and the vehicle needs to get out of trouble. When the vehicle is off-road on mud or sand, when the vehicle is driving in the mud, the adhesion of the wheels to the ground is very small, and the ESP will activate to brake some of the wheels. At this time, the engine torque will be continuously consumed by the wheels with less rolling resistance, and the ESP will limit the speed of the engine, even if you step on the accelerator, it must be difficult to get out of trouble, in this case, the driver needs to manually turn off the ESP, so that the vehicle power output is full to drive the vehicle out of trouble.

On ice and snow roads, when installing snow chains on the vehicle, the car with snow chains installed may cause the detection signals such as wheel speed sensors and lateral acceleration sensors to be inaccurate, and it will also affect the normal operation of the ESP system, and the ESP misjudgment will continue to intervene and cause the vehicle to run unsmoothly.

Summary:

If the car safety configuration is used well, it can make us easy to drive, and if it is not used well, it is easy to bring us a lot of trouble.
