VEHICLE SPEED CONTROL SYSTEM

摘要

A vehicle speed control system for a vehicle having a plurality of wheels, the vehicle speed control system comprising one or more electronic control units configured to carry out a method that includes applying torque to at least one of the plurality of wheels, detecting a slip event between any one or more of the wheels and the ground over which the vehicle is travelling when the vehicle is in motion and providing a slip detection output signal in the event thereof. The method carried out by the one or more electronic control units further includes receiving a user input of a target speed at which the vehicle is intended to travel and maintaining the vehicle at the target speed independently of the slip detection output signal by adjusting the amount of torque applied to the at least one of the plurality of wheels.

1. A vehicle speed control system for a vehicle having a plurality of wheels, the vehicle speed control system configured to automatically control the speed of the vehicle to a target speed and comprising one or more electronic control units arranged to:
control the application of torque to at least one of the plurality of wheels; detect a slip event between any one or more of the wheels and the surface over which the vehicle is travelling when the vehicle is in motion and provide a slip detection output signal in the event thereof; receive a user input of a target set-speed at which the vehicle is intended to travel; and control the application of torque to the at least one of the plurality of wheels for maintaining the vehicle at the target speed independently of the slip detection output signal by requesting the application of increased net torque to the at least one of the plurality of wheels when the vehicle speed needs to be increased to maintain the vehicle at the target speed wherein the magnitude of the requested increased net torque is reduced when an identified external force acts on the vehicle in a direction so as to cause positive acceleration.
