Abstract
A control system (400) is provided for an adjustable suspension of a vehicle (100). The adjustable suspension is operable in at least two different configurations. The control system is configured to receive route data (110) indicative of an expected route of the vehicle, receive map data (120) comprising road type information for a road section of the expected route, and output a switch signal to instruct the adjustable suspension (104) to switch between the two different configurations in dependence on the expected route and the road type information, before the vehicle (100) reaches the road section.

The control system for an adjustable suspension of a vehicle, the adjustable suspension being operable in at least two different configurations, the control system comprising one or more controllers 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,
- wherein the control system is configured to estimate a stable stretch of road indicative of a length of road wherein, after an initial switching between the two configurations, the suspension can remain in the switched-to configuration, and to output the switch signal in dependence on the estimated stable stretch of road.
A method of controlling an adjustable suspension of a vehicle, the adjustable suspension being operable in at least two different configurations, the method comprising:
- receiving route data indicative of an expected route of the vehicle;
- receiving map data comprising road type information for a road section of the expected route;
- and
- outputting 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;
- wherein the method comprises estimating a stable stretch of road indicative of a length of road wherein, after an initial switching between the two configurations, the suspension can remain in the switched-to configuration, and outputting the switch signal in dependence on the estimated stable stretch of road.
