Abstract
Aspects of the present invention relate to a method and to a control system for controlling an active suspension of a vehicle, the control system comprising one or more controllers, the control system configured to: obtain information indicative of a change of gradient of a driving surface in a direction of travel; and control the active suspension to adjust relative ride height between a front and rear of a vehicle body of the vehicle above the driving surface beneath the vehicle in dependence on the change of gradient.
Claims15
A control system for controlling an active suspension of a vehicle, the control system comprising one or more controllers, the control system configured to:
- obtain information indicative of a change of gradient of a driving surface in a direction of travel;
- obtain a target adjustment for causing a deviation of pitch angle between the vehicle body and an angle of the driving surface beneath the vehicle;
- and
- control the active suspension to control relative ride height between a front and rear of a vehicle body of the vehicle above the driving surface beneath the vehicle in dependence on the change of gradient, wherein the control of relative ride height between the front and rear of the vehicle body is towards the target adjustment.
A method of controlling an active suspension of a vehicle, the method comprising:
- obtaining information indicative of a change of gradient of a driving surface in a direction of travel;
- obtaining a target adjustment for causing a deviation of pitch angle between the vehicle body and an angle of the driving surface beneath the vehicle;
- and
- controlling the active suspension to control relative ride height between a front and rear of a vehicle body of the vehicle above the driving surface beneath the vehicle in dependence on the change of gradient, wherein the control of relative ride height between the front and rear of the vehicle body is towards the target adjustment.
