Aspects of the present invention relate to a control system (100, 200) for a vehicle suspension system of a vehicle (800). The control system is configured to perform a test for testing operation of the isolation switch (430). A vehicle suspension system includes an actuator power supply (450) configured to supply power to the vehicle suspension system. The actuator power supply is configured to be electrically connected to the vehicle suspension system via the isolation switch. The control system is configured to: receive a closing indication signal indicating that the vehicle is in a closed state (530); outputting an open disconnector signal (524) configured to open the disconnector according to the closing indication signal; receiving an open disconnector acknowledgement signal (516) indicating that the disconnector is open; determining whether a disconnecting switch disconnection confirmation signal is received within a predetermined time period; and outputting a test pass signal or a test failure signal according to the determination.
本发明的各方面涉及用于车辆(800)的车辆悬架系统的控制系统(100,200)。控制系统被配置成执行用于测试隔离开关(430)的操作的测试。车辆悬架系统包括被配置成向该车辆悬架系统供应电力的致动器电源(450)。致动器电源被配置成经由隔离开关电连接至车辆悬架系统。控制系统被配置成:接收指示车辆处于关闭状态(530)的关闭指示信号;根据关闭指示信号,输出被配置成断开隔离开关的断开隔离开关信号(524);接收指示隔离开关断开的断开隔离开关确认信号(516);确定是否在预定时间段内接收到断开隔离开关确认信号;以及根据所述确定,输出测试通过信号或测试失败信号。
