What is the significance of traction control for automobile assisted driving?

The traction control of automobile assisted driving is a computer, which detects the speed of four wheels and the steering angle of the steering wheel. When the car is accelerating, if the speed difference between the driving wheel and the non-driving wheel is too large, the computer immediately judges that the driving force is too large, and sends out command signals to reduce the fuel supply and driving force of the engine, thus reducing the slip rate of the driving wheel.

Its purpose is to prevent vehicles, especially high-powered vehicles, from slipping when starting and accelerating, so as to maintain the stability of vehicle driving direction.

On vehicles equipped with ASR, the mechanical connection from the accelerator pedal to the gasoline engine throttle (diesel fuel injection pump joystick) is replaced by an electronic throttle device. When the sensor transmits the position and wheel speed signal of the accelerator pedal to the control unit, the control unit will generate a control voltage signal, and the servo motor will readjust the position of the accelerator (or the position of the diesel engine joystick) according to this signal, and then feed back the position signal to the control unit so as to adjust the braking in time.

Traction control system relies on electronic sensors to detect that the speed of the driven wheel is lower than that of the driving wheel (which is the characteristic of skidding), and it will send a signal to adjust the ignition time, reduce the valve opening, reduce the throttle, downshift or brake the wheel to stop skidding.

Extended data

Driver assistance system:

1) Super anti-shake camera, the image is clearer. In order to meet the requirements of the mobile working condition of the machine, all the hardware and connectors in the machine have been strengthened by earthquake prevention. Professional anti-seismic structure design provides super cushioning and anti-seismic protection for the machine, and combines electronic anti-seismic and software anti-seismic technologies to effectively solve the impact and vibration problems of vehicles.

2) The video adopts the revised MJPEG+ compression format, which is high definition and supports the recording speed of 30FPS. Video files can be displayed in real time by connecting DVD, navigator and independent monitor.

3) Support four simultaneous video recording, recording, storage, projection and real-time display functions.

4) During driving, the control is simple, and the required picture can be automatically switched according to the driving state. (For example, when the car turns right, the LCD display image only shows the image taken by the camera on the right. ) You can also force screen switching.

5) Battery power supply or vehicle power supply is adopted, and advanced technology is adopted to realize low power consumption.

6) Search and play functions can be quickly found according to date and time.
