The invention relates to a control unit and a method for controlling wheels on a vehicle. A control unit for controlling a torque applied to a wheel of a vehicle provided with a tire is disclosed, where the control unit comprises or is operatively connected to a data storage device having a stored tire model for the tire, where in the tire model, the torque applied to the wheel of the vehicle provided with the tire is transmitted to the control unit. The longitudinal tire force is represented at least as a function of a longitudinal wheel slip, which depends on the rotational speed of the wheel and the rate of the vehicle. The control unit is configured to: correct the function based on the tire parameter input, and convert the wheel torque request to a wheel speed request based on the corrected function; and sending a wheel speed request to an actuator to provide a wheel speed corresponding to the wheel speed request. The invention also relates to a method and a kit.
本发明涉及用于控制车辆上的车轮的控制单元和方法。公开了一种用于控制向设置有轮胎的车辆车轮施加的扭矩的控制单元,其中,控制单元包括或可操作地连接到数据存储设备,该数据存储设备具有用于轮胎的所存储的轮胎模型,其中,在该轮胎模型中,纵向轮胎力至少表示为纵向车轮滑移的函数,纵向车轮滑移取决于车轮的转速和车辆的速率。控制单元被配置成:基于轮胎参数输入校正所述函数,并且基于经校正的函数将车轮扭矩请求转换成车轮转速请求;以及将车轮转速请求发送到致动器,以提供与所述车轮转速请求相对应的车轮转速。本发明也涉及一种方法和一种套件。
