A control system () is provided for an adjustable suspension of a vehicle (). The adjustable suspension is operable in at least two different configurations. The control system is configured to receive route data () indicative of an expected route of the vehicle, receive map data () comprising road type information for a road section of the expected route, and output a switch signal to instruct the adjustable suspension () to switch between the two different configurations in dependence on the expected route and the road type information, before the vehicle () reaches the road section.

Vehicle suspension control system

An actuator system for a vehicle suspension system includes: an actuator having a piston and a first fluid chamber separated from a second fluid chamber by the piston; a hydraulic pump having a first port connected by a first hydraulic circuit to the first chamber via a first valve, the first valve being a damper valve operable to variably restrict flow of hydraulic fluid out of the first chamber; a first hydraulic accumulator connected to the first hydraulic circuit between the first port and the first valve; and a second hydraulic accumulator connected to the first port by a second valve, the second valve being a variable pressure relief valve operable to variably restrict flow of hydraulic fluid from the first port to the second hydraulic accumulator.
