What does vehicle traction mean?

[LeKatherine]

Vehicle traction refers to the force generated by the friction between the wheels and the ground that propels the car forward, also known as the driving force of the vehicle, which is the power that drives the car to move. The function of vehicle traction is to prevent the driving wheels from spinning when the vehicle is driving on slippery surfaces such as snow, as well as to prevent the driving wheels from slipping during the car's starting and acceleration processes. It includes brake torque control and engine torque control. The working principle of vehicle traction is: the computer detects the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if the computer detects that the speed difference between the driving wheels and non-driving wheels is too large, it immediately determines that the driving force is excessive, sends a command signal to reduce the fuel supply to the engine, thereby reducing the driving force and decreasing the slip rate of the driving wheels.
