Abstract
Disclosed in processing circuitry for a vehicle. The processing circuitry is configured to obtain, for at least two wheels of the vehicle, a slip ratio and a slip angle. The slip ratio has a non-linear relationship to the wheel rotational speed and the wheel centre point velocity. The slip angle has a non-linear relationship to the wheel centre point velocity. The processing circuitry is configured to obtain, for each wheel, a wheel longitudinal force and a wheel lateral force. The wheel longitudinal force has a linear dependence on the slip ratio. The wheel lateral force has a linear dependence on the slip angle. The processing circuitry is configured to determine a target yaw rate of the vehicle based on the slip ratio, the slip angle, the wheel longitudinal force, and the wheel lateral force for each wheel.
