ABSTRACT:
A desired value for the yaw velocity or the difference between the wheel speeds of the undriven wheels is determined with the aid of a linear single-track model using the steering angle and the vehicle speed. This desired value is compared with the corresponding actual value and the controlled variable for the adjustment to the engine torque is obtained from the comparison. To avoid unnecessary control operations, the single-track model has connected to its output an all-pass element which matches the phase rotation of the response of the single-track model at high frequencies to that of the vehicle.
