Abstract
A control system for a vehicle is provided, the control system comprising one or more controllers, the control system configured to identify an upcoming speed limit change, and in dependence on the identified speed limit change, requesting modification of one or more parameters of the vehicle suspension system. This prepares the vehicle suspension to reduce pitch forwards/backwards at a time when an acceleration/deceleration can be expected, while allowing more composed vehicle suspension settings to be used at other times.
Claims19
A control system for a vehicle, the control system comprising one or more controllers, the control system configured to:
- identify an upcoming speed limit change;
- in dependence on the identified speed limit change, request modification of one or more parameters of a vehicle suspension system;
- and
- monitor a position of the vehicle in relation to the speed limit change, determine an amount of longitudinal acceleration or deceleration required for the vehicle to satisfy the upcoming speed limit change, and request the modification of the one or more parameters of the vehicle suspension system in dependence on the determined amount of longitudinal acceleration or deceleration.
A control system for a vehicle, the control system comprising one or more controllers, the control system configured to:
- identify an upcoming speed limit change;
- and
- in dependence on the identified speed limit change, request modification of one or more parameters of a vehicle suspension system, wherein the modification is requested only when a distance or time window between the vehicle and the speed limit change is less than a predetermined value.
A control system for a vehicle, the control system comprising one or more controllers, the control system configured to:
- identify an upcoming speed limit change;
- in dependence on the identified speed limit change, request modification of one or more parameters of a vehicle suspension system;
- and
- request the modification in dependence on a detection of a driver-induced acceleration or deceleration demand, or an acceleration or deceleration of the vehicle, during a predetermined distance or time window in advance of the speed limit change.
A control system for a vehicle, the control system comprising one or more controllers, the control system configured to:
- identify an upcoming speed limit change;
- in dependence on the identified speed limit change, request modification of one or more parameters of a vehicle suspension system;
- and
- monitor a position of the vehicle in relation to the upcoming speed limit change and wherein the modification is requested only when a distance or time window between the vehicle and the speed limit change is less than a predetermined value.
A control method for a vehicle suspension system of a vehicle, the control method comprising:
- identifying an upcoming speed limit change;
- in dependence on the identified speed limit change, requesting modification of one or more parameters of the vehicle suspension system;
- and
- monitoring a position of the vehicle in relation to the upcoming speed limit change, determining an amount of longitudinal acceleration or deceleration required for the vehicle to satisfy the upcoming speed limit change based on a current vehicle speed, the upcoming speed limit change, and a distance from the vehicle to the speed limit change, and requesting the modification of the one or more parameters of the vehicle suspension system in dependence on the determined amount of longitudinal acceleration or deceleration.
A control method for a vehicle suspension system of a vehicle, the control method comprising:
- identifying an upcoming speed limit change;
- in dependence on the identified speed limit change, requesting modification of one or more parameters of the vehicle suspension system;
- and
- monitoring a position of the vehicle in relation to the upcoming speed limit change and wherein the modification is requested only when a distance or time window between the vehicle and the speed limit change is less than a predetermined value.
