    Abstract: 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 an isolation switch (430). The vehicle suspension system comprises 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 shutdown indicator signal indicating that the vehicle is in a shutdown state (530); output an open isolation switch signal (524) configured to open the isolation switch in dependence on the shutdown indicator signal; receive an open isolation switch confirmation signal (516) indicative of the isolation switch being open; determine whether the open isolation switch confirmation signal is received within a predetermined time period; and output a test pass signal or a test failure signal in dependence on the determination.

    Abstract: Aspects of the present invention relate to a control system (100, 200) for a vehicle suspension system of a vehicle. The vehicle suspension system comprises a plurality of connected subsystems (302, 304, 306). The control system comprises one or more controllers (110). The control system is configured to: determine if a first subsystem (302) of the plurality of connected subsystems has entered a fault state (312-2), wherein the fault state is an abnormal operating state (402); determine a compensatory operating state (314-2, 316-2) of a further subsystem of the plurality of electrically connected subsystems, in dependence on determining that the first subsystem has entered the fault state, wherein the further subsystem operating in the compensatory operating state, with the first subsystem operating in the fault state, causes the vehicle suspension system to operate in a higher vehicle stability mode in comparison to the vehicle suspension system operating with the first subsystem operating in the fault state without the further subsystem operating in the compensatory operating state (404); and output, to the further subsystem, in dependence on determining the compensatory operating state, a compensatory operation signal (155) to cause the further subsystem to operate in the compensatory operating state with the first subsystem operating in the fault state (406).

    Abstract: A system includes: a state module configured to selectively set a present state to a first state; a valve control module configured to determine first target open and closed states for valves of a suspension system based on the present state and to open and close the valves according to the first target open and closed states, respectively; a pump control module configured to, when the valves are in the first target open and closed states, respectively, selectively operate an electric pump in a first direction to increase hydraulic fluid pressure in a first portion of the suspension system; and a leak module configured to selectively diagnose a leak in a first one of the valves associated with the first state based on a first pressure in the first portion of the suspension system while the valves are open and closed according to the first target open and closed states.

    Abstract: A vehicle includes a high voltage component such as an electric actuator, an electric suspension control ECU, a battery, a signal line which transmits, to the electric suspension control ECU, a detection signal of a sensor disposed in the electric actuator, a high voltage line which supplies a high voltage from the battery to the electric actuator, and a fixing member which fixes the signal line and the high voltage line to a vehicle body, a length of the signal line from the fixing member to the electric actuator is shorter than a length of the high voltage line from the fixing member to the electric actuator, and the electric suspension control ECU suppresses the supply of the high voltage to the electric actuator, in a case where abnormality occurs in the signal line.
