Traction-control-system e.g. engine and brake-type traction control system, controlling method for motor vehicle, involves determining dynamic normal load for wheel and modifying requested torque in response to load to form modified torque

摘要

The method involves determining a dynamic normal load for a vehicle wheel in response to a lateral acceleration, a longitudinal acceleration, a yaw rate, a yaw acceleration or a difference in non-driven wheel speeds. A requested torque is modified from a traction control system in response to the dynamic normal load to form a modified requested torque. The control system is controlled in response to the modified requested torque.
