A control system (300) for controlling an active suspension system (104) of a vehicle (100) to determine a relative traction level, the control system comprising one or more controllers (301) wherein the control system is configured (908) to: control the active suspension system to vary a normal force through a first subset of one or more wheels; determining a traction-related variable at each wheel of the first subset of wheels to which the known torque is applied; controlling the active suspension system to vary the normal force through the one or more wheels of the second subset; and determining a traction-related variable at each wheel of the second subset of wheels to which the known torque is applied, where the traction-related variables indicate the relative traction level.
一种用于控制车辆(100)的主动悬架系统(104)以确定相对牵引力水平的控制系统(300),该控制系统包括一个或更多个控制器(301),其中,该控制系统配置(908)成:将主动悬架系统控制成改变通过第一子组的一个或更多个车轮的法向力;确定被施加已知扭矩的第一子组的车轮中的每个车轮处的牵引力相关的变量;将主动悬架系统控制成改变通过第二子组的一个或更多个车轮的法向力;以及确定被施加已知扭矩的第二子组的车轮中的每个车轮处的牵引力相关的变量,其中,牵引力相关的变量指示相对牵引力水平。
