Abstract
Aspects of the present invention relate to a control system, a suspension system, a vehicle and a method. A control system comprising one or more controllers is configured to: receive at least one vehicle dynamics signal, wherein the at least one vehicle dynamics signal is indicative of a vehicle dynamics parameter, determine a current dynamic usage of a vehicle in dependence on the received at least one vehicle dynamics signal, determine a control parameter for an actuator of the vehicle in dependence at least in part on the current dynamic usage of the vehicle, and output a control signal to control the actuator in dependence on the control parameter.

A control system for a vehicle suspension system, the control system comprising one or more controllers configured to:
- receive at least one vehicle dynamics signal, wherein the at least one vehicle dynamics signal is indicative of a movement of one or more components of the vehicle suspension system;
- determine a current dynamic usage of a vehicle in dependence on the received at least one vehicle dynamics signal, wherein determining the current dynamic usage of the vehicle comprises determining at least one vehicle usage index by determining an average movement value of the movement of the one or more components of the vehicle suspension system over a duration, the average movement value including an average of an anti-roll torque demand;
- determine an operating limit for a control parameter of an actuator of the vehicle suspension system in dependence at least in part on the vehicle usage index;
- and
- output a control signal to control the actuator in dependence on the operating limit.
A method of controlling a vehicle suspension system, the method comprising:
- receiving at least one vehicle dynamics signal, wherein the at least one vehicle dynamics signal is indicative of a movement of one or more components of the vehicle suspension system
- determining a current dynamic usage of a vehicle in dependence on at least one vehicle dynamics parameter, wherein determining the current dynamic usage of the vehicle comprises determining at least one vehicle usage index by determining an average movement value of the movement of the one or more components of the vehicle suspension system over a duration, the average movement value including an average of an anti-roll torque demand;
- determining an operating limit for a control parameter of an actuator of the vehicle suspension system in dependence at least in part on the current dynamic usage of the vehicle;
- and
- controlling the actuator in dependence on the operating limit.
