Aspects relate to control systems and methods for a vehicle suspension system in a vehicle. A control system (100, 200) is configured to: receive a perturbation angle (316) of a roll bar of a vehicle suspension system, the perturbation angle indicating a determined relative angular displacement between ends of the roll bar caused by a vehicle interaction with a driving surface; receiving a displacement value (322) of an actuator motor of an actuator of the vehicle suspension system, the displacement value of the actuator motor indicating sensed displacement of the actuator motor caused by vehicle interaction with the driving surface; determining a torque estimate (332) from the disturbance angle of the roll bar and the displacement value of the actuator motor, the torque estimate representing a torque expected to be provided by the actuator motor to the roll bar connected to the actuator motor; and outputting the torque estimate to a further vehicle system.
各方面涉及用于车辆中的车辆悬架系统的控制系统和方法。控制系统(100,200)被配置成:接收车辆悬架系统的侧倾杆的扰动角(316),该扰动角指示所确定的由车辆与行驶表面相互作用引起的侧倾杆的端部之间的相对角位移;接收车辆悬架系统的致动器的致动器马达的位移值(322),该致动器马达的位移值指示所感测的由车辆与行驶表面相互作用引起的致动器马达的位移;根据侧倾杆的扰动角和致动器马达的位移值确定扭矩估计(332),该扭矩估计表示预期由致动器马达向连接至致动器马达的侧倾杆提供的扭矩;以及将扭矩估计输出至进一步的车辆系统。
