Abstract
The invention concerns a steering and braking system for a motor vehicle which has wheels on opposite sides thereof. Each wheel has a brake unit that can be controlled by an operator actuating a brake device, such as a brake pedal. At least one of the brake units is controlled in response to a turning maneuver of the motor vehicle independent of the actuation of the brake pedal, so that a higher braking force is applied to an inside one of the brake units with respect to the curve than is applied to an outside one of the brake units with respect to the curve.
Claims7
A steering and braking system for a motor vehicle having left and right vehicle wheels, left and right hydraulic brake units for braking the corresponding wheels, the steering and braking system comprising:
- a hydraulic pump;
- a steering control valve;
- an operator controlled brake operating element;
- a hydraulic brake valve controlled by the operating element, the brake valve being connected to each of the brake units by a corresponding hydraulic brake line;
- a pair of pressure control valves, each pressure control valve being connected between the pump and a corresponding one of the brake units, and each pressure control valve having a control input connected to the steering valve, and in response to a turning of the vehicle in a curve, the steering control valve causing one of the pressure control valves connected to an inside one of the brake units with respect to the curve to connect the pump to said inside brake unit to apply a higher braking force to said inside brake unit than to an outside one of the brake units with respect to the curve.
