ABSTRACT:
A vehicle traction control device having a control device for controlling the torque of the drive wheels by controlling the throttle in order to match the slip rate of the drive wheels with a target slip rate in order to prevent excessive slip caused by excessive torque in the drive wheels. The traction control is provided with a device for determining whether or not the road being driven on is a rough road or not. When the above device sends a signal to the control that the road is rough, the engine gain in the throttle is made smaller when the throttle closed relative to the engine gain and throttle of a normal road. In another embodiment, when the road is rough, the engine gain is made larger when the throttle is opened relative to the engine gain and throttle of a normal road. Also disclosed is a control in which the engine gain in the throttle control is made larger when the throttle is opened and is made smaller when the throttle is closed relative to the engine gain and throttle of a normal road. A process for controlling traction is also disclosed.
