Abstract
A vehicle speed control system that carries out a method of: automatically causing application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value v_target; controlling a rate of change of speed of the vehicle by application of positive and negative torque to one or more wheels; and receiving information relating to a terrain response mode in which the vehicle is configured or an amount of drag imposed on a vehicle. The system is configured to control the rate of change of speed in dependence at least in part on the terrain response mode, the amount of drag imposed on the vehicle, or both.
Claims20
A speed control system for a vehicle, comprising:
- an electronic processor having an electrical input for receiving signals indicative of at least one of a terrain response mode in which the vehicle is configured and an amount of drag imposed on a vehicle;
- and
- an electronic memory device electrically coupled to the electronic processor and having instructions stored therein,
- wherein the processor is configured to access the memory device and execute the instructions to:
- automatically cause application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value;
- and
- control a rate of change of speed of the vehicle
- in dependence at least in part on the signals indicative of at least one of the terrain response mode in which the vehicle is configured and the amount of drag imposed on a vehicle by commanding application of positive and negative torque to one or more wheels.
A method of controlling a vehicle, comprising:
- automatically causing application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value;
- controlling a rate of change of speed of a vehicle by application of positive and negative torque to one or more wheels using an electronic processor;
- and
- receiving information relating to one or more of a terrain response mode in which the vehicle is configured and an amount of drag imposed on a vehicle,
- the method comprising controlling the rate of change of speed in dependence at least in part on said one or more of a terrain response mode in which the vehicle is configured and an amount of drag imposed on a vehicle.
A non-transitory, computer-readable storage medium storing instructions thereon that when executed by one or more electronic processors causes the one or more electronic processors to carry out a method of:
- automatically causing application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value;
- controlling a rate of change of speed of a vehicle by application of positive and negative torque to one or more wheels;
- and
- receiving information relating to one or more of a terrain response mode in which the vehicle is configured and an amount of drag imposed on a vehicle,
- the method comprising controlling the rate of change of speed in dependence at least in part on said one or more of a terrain response mode in which the vehicle is configured and an amount of drag imposed on a vehicle.
