Brake control
First Claim
Patent Images
1. A method for controlling the brakes of a motor vehicle, the method comprising:
- determining whether the vehicle is travelling in an intended direction of travel or an unintended direction of travel with reference to a selected gear;
setting an acceleration limit of the vehicle in dependence on the determined direction of travel, with the acceleration limit being set lower when the vehicle is moving in an unintended direction than when the vehicle is moving in an intended direction;
determining an acceleration of the vehicle; and
, if the determined acceleration exceeds the set acceleration limit, ensuring that the brakes apply a braking effort.

Abstract
A brake control system for a motor vehicle having a plurality of wheels, brakes for applying a braking effort to one or more of the wheels, and movement sensing means for detecting movement of the vehicle. The system comprises: brake actuation means for actuating the brakes to supply a braking effort; and brake control means for controlling the brake actuation means, wherein the brake control means is arranged to determine an acceleration of the vehicle based on movement detected by the movement sensing means and to ensure that the brake actuation means supplies a braking effort if the determined acceleration exceeds a set acceleration limit.

8. A brake control system for a motor vehicle having a plurality of wheels, brakes for applying a braking effort to one or more of the wheels, and movement sensing means for detecting movement of the vehicle, the system comprising:
- brake actuation means for actuating the brakes to supply a braking effort; and
brake control means for controlling the brake actuation means, wherein the brake control means is arranged;
i) to determine an acceleration of the vehicle based on movement detected by the movement sensing means and to ensure that the brake actuation means supplies a braking effort if the determined acceleration exceeds a set acceleration limit; and
ii) to measure a desired drive torque and to set the acceleration limit dynamically based on the desired drive torque and to increase the set acceleration limit with increasing desired drive torque;wherein the brake control means is arranged to set the acceleration limit in dependence on a gradient of the vehicle; and wherein the brake control means is arranged to lower said acceleration limit in response to an increased gradient of the vehicle.
