Abstract: Aspects relate to systems and methods for pre-emptively managing suspension loads. A control system (100, 200) is configured to receive a driving surface signal (165) indicative of a property of a driving surface ahead of the vehicle (600). The control system is further configured to determine, in dependence on the received driving surface signal and on a current vehicle operational state, an attribute parameter. The attribute parameter, when provided to an actuator (318a, 318b . . . 318z) of the suspension system, causes the actuator to act to control a suspension force acting on the suspension system due to a movement of the vehicle along the driving surface to be below a predetermined suspension force value. The control system is further configured to output an actuator control signal (155) to the actuator of the suspension system to control the actuator in dependence on the determined attribute parameter.

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).
