Abstract
An electronic vehicle stability control system includes a hydraulic braking circuit having a plurality of electronically controlled valves, a plurality of pumps, a motor that operates the plurality of pumps, and a suction throttle valve that throttles flow of hydraulic fluid to at least one of the plurality of pumps. The electronic vehicle stability control system also includes a controller coupled to the hydraulic braking circuit that controls the plurality of electronically controlled valves.
Claims29
An electronic vehicle stability control system comprising:
- a hydraulic braking circuit having a plurality of electronically controlled valves, a plurality of pumps, a motor that operates the plurality of pumps, and a suction throttle valve that throttles flow of hydraulic fluid to at least one of the plurality of pumps;
- and
- a controller coupled to the hydraulic braking circuit that controls the plurality of electronically controlled valves.
An electronic vehicle stability control system comprising:
- a brake pedal;
- a master cylinder coupled to the brake pedal;
- a first set of wheels;
- a second set of wheels;
- a hydraulic braking system coupled to the master cylinder, the hydraulic braking system including a first hydraulic braking circuit that directs hydraulic fluid from the master cylinder to the first set of wheels, and a second hydraulic braking circuit that directs hydraulic fluid from the master cylinder to the second set of wheels, wherein each of the first hydraulic braking circuit and the second hydraulic braking circuit includes a plurality of electronically controlled valves, a plurality of pumps, and a suction throttle valve that throttles flow of hydraulic fluid to at least one of the plurality of pumps;
- and
- a controller coupled to the hydraulic braking system that controls the plurality of electronically controlled valves.
A method of operating an electronic stability control system comprising:
- directing hydraulic fluid to a plurality of pumps within a hydraulic braking circuit;
- and
- throttling a flow of the hydraulic fluid to at least one of the pumps with a suction throttle valve.
