US 2016/0244057 A1 · IMPROVEMENTS IN VEHICLE SPEED CONTROL

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.

Claims23

Dependent claims

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 stored therein such that it is operable 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.
