What is Automotive ACC? What does car acc mean?

ACC is a set of DU control system to ensure safe and comfortable driving, Chinese means zhi adaptive cruise control power supply, a DAO general application to the car controlled by the car key, for the car audio and other parts of the power supply.

While the vehicle is moving, a distance sensor (radar) mounted on the front of the vehicle continuously scans the road in front of the vehicle, while the wheel speed sensor collects the vehicle speed signal. When the distance between the vehicle in front and the vehicle in front is too small, the ACC control unit can coordinate with the anti-lock braking system and the engine control system to make the wheels brake properly and reduce the output power of the engine, so that the vehicle and the vehicle in front always maintain a safe distance.

ACC is the English abbreviation of adaptive cruise control, Chinese means adaptive cruise control power supply, generally used in cars controlled by car keys, for car audio and other parts of the power supply.

Answer: The ACC status of the car is the opening and closing state of the key door.

1. The general car key has 4 gears, one is "off", one is "ACC", the other is "on", and the other is the start gear, but most Volkswagen models (like Hongqi, Audi, etc.) are 3 gears, that is, there is no ACC" gear.

2. The "off" gear is "off", and the "acc" gear is "the car can supply power to some electrical appliances in the car without starting the car". The "on" gear is "to supply power to all electrical appliances in the car", and the starting gear is a self-resetting switch, which automatically returns to the "on" gear after starting the car.

There are different meanings, the ACC gear of the ignition switch is the gear of the special receiver, and there is also the ACC to represent the speed sensor, so different systems in different cars also represent different meanings.

The simple understanding is the adaptive cruise function. It is a higher level of technology than cruise control.

Hello, part of the meaning of electrification with electrical appliances.

The first is to use the traditional key mechanical tooth inserted into the ignition switch, and the ignition switch can be turned on by turning the key to start the vehicle.

In this way, the ignition switch will be divided into four gears, that is, the lock gear: the state when the car is locked, at this time, the direction is locked, and the power supply of the whole car is also cut off; ACC status: turn on the power supply of some electrical equipment of the car, such as air conditioner, CD, etc.; ON Status:

Turn on all power supplies, the trip computer starts self-checking, and it is in this state when driving; Start state: This is the gear of the engine start, which will naturally return to the ON state after starting;

The second type of ACC is the adaptive cruise control system.

Adaptive cruise control, also known as active cruise control, is similar to traditional cruise control, which includes radar sensors, digital signal processors, and control modules.

When the obstacle in front of the road is cleared, it accelerates back to the set speed, and the radar system automatically monitors the next target. ACC controls the speed of the vehicle on behalf of the driver, avoiding frequent cancellations and setting cruise control. Adaptive cruise control is suitable for a wide range of road conditions, providing a more relaxed way for the driver.

Notes:

At present, the widely equipped forward-looking millimeter-wave radar camera solution, the radar is actually not very concerned with fixed obstacles. Because the reflection near the ground is too chaotic, the Doppler effect is generally used to filter out the reflected waves of fixed objects before target recognition. This method is more accurate for measuring moving vehicles, but for fixed objects, it is mainly recognized by cameras.

It should be noted that for Doppler radar, the object crossing the road is a fixed object, so the current stage of adaptive cruise, although the car can drive itself in the lane, but still requires the driver to pay attention to the driving state at all times, theoretically just a little lighter.

ACC power supply, a power supply for automobiles, is controlled by a car key and supplies power to some devices such as car stereos.

ACC: Literally means accessory, in the car, ACC refers to before the car starts, if there is a key ACC file, as long as the key is dialed to this position, some equipment that does not use too much electricity, such as: radio, cigarette lighter, etc. will be energized, when the car is ignited, a strong current is needed, then the ACC bit stops supplying power, and when the car ignition ends, the power supply starts again.

ACC is Cavity Adaptive Cruise Control.

Adaptive cruise control detection.

It is an intelligent automatic control system.

It was developed on the basis of pre-existing cruise control technology.

Adaptive cruise control systems utilize low-power radar or infrared.

The beam gets the exact location of the front car in Na Wu State. If the vehicle in front is slowing down or a new target is detected, the system sends an execution signal to the engine or braking system.

to reduce the speed of the vehicle and maintain a safe driving distance between the vehicle and the vehicle in front.

Introduce. When controlling the vehicle's braking, the automotive adaptive cruise control system usually limits the braking deceleration to a level that does not affect comfort, and when greater deceleration is required, the ACC control unit will send an audible and visual signal to notify the driver to take the initiative to brake. When the distance to the vehicle in front increases to a safe distance, the ACC control unit controls the vehicle to drive at a set speed.

ACC can generally enter the cruise at a lower speed, in addition to high-speed road conditions, it can also be applied to urban road conditions, and there is no need to worry too much about traffic jams and stop-and-go state. The car's sensors will calculate and judge the driving status of the vehicle in front and the vehicle, and then send instructions to the actuator to determine its driving status, whether to accelerate or decelerate, or exit the cruise.

The most basic function of adaptive cruise control is to keep the vehicle longitudinal, and in the event of a collision, the vehicle will alert the driver and intervene with active braking. Moreover, when the distance between the vehicle in front and the vehicle in front is too small, the ACC control unit can coordinate with the brake anti-lock braking system and the engine control system to make the wheels brake properly and make the engine output power.

Descend so that the vehicle is always at a safe distance from the vehicle in front. In general, ACC reduces the driver's driving fatigue to a certain extent.

ACC is the English abbreviation of adaptive cruise control, Chinese means adaptive cruise control power supply, generally used in cars controlled by car keys, for car audio and other parts of the power supply.

Adaptive cruise control is similar to traditional automatic cruise control, with a system consisting of radar sensors, digital signal processors and control modules that allow the driver to set the desired speed and the system to determine the exact position of the vehicle in front using low-power radar or infrared beams.

If the vehicle in front is slowing down or detects a new target, the system sends an execution signal to the engine or braking system to reduce the speed of the vehicle and maintain a safe distance between the vehicle and the vehicle in front.
