What Causes the Failure of Hill Start Assist Function?

[StCorbin]

Hill start assist function failure is related to sensors. Sensor malfunction: It may be caused by sensor failure. The hill start assist system mainly relies on two sensors to function. If the sensors fail, the hill start assist function will not work properly. Principle of hill start assist system: The hill start assist system relies on two sensors: one is the vehicle longitudinal position balance sensor, and the other is the tire torque sensor, which mainly monitors the negative torque of the tires. The hill start assist system includes uphill assist and downhill assist. Uphill assist prevents the vehicle from rolling backward when starting on an uphill slope, while downhill assist controls the braking system on steep downhill slopes to maintain a certain speed.
