When a car brakes on a smooth road, its wheels will slip and even lose control of the direction.
Similarly, when the car starts or accelerates rapidly, the driving wheel is also likely to slip, and the direction will be out of control on smooth roads such as snow and ice.
The traction control system is designed for this problem.
Traction control relies on electronic sensors to detect when the slave wheels are moving slower than the driving wheels and send a signal to adjust ignition timing, reduce valve opening, and throttle, shift or brake the wheels so they don’t slip.
Traction control system can not only improve the driving stability of the vehicle, but also improve the acceleration and climb ability.
If the traction control system and ABS are used together, the safety performance of the car will be further enhanced.
Traction control system and ABS can share the wheel speed sensor on the axle, and connected with the driving computer, constantly monitor the speed of each wheel, when the skid is found at low speed, traction control system will immediately inform ABS action to reduce the wheel skid.
If the high speed found skid, traction control system immediately to the driving computer command, command engine speed or transmission gear down, so that the skid wheel no longer skid, prevent the vehicle out of control tail.
The traction control system using computer detection of four wheel steering wheel speed and steering Angle, when the car speed up, if detection to the driving wheels and the driving wheel speed difference is too big, the computer immediately determine driving force is too large, a command signal to reduce engine oil, reduce the driving force, so as to reduce the driving wheel tire slip rate.
The computer learns the driver’s steering intention through the steering wheel Angle sensor, and then uses the left and right wheel speed sensor to detect the speed difference between the left and right wheels.
To judge whether the car steering degree and the driver’s steering intention is the same.
If understeer is detected, the computer immediately determines that the driving force of the driving wheels is too large and gives instructions to reduce the driving force to achieve the driver’s steering intention.
