A method to control a hydraulic pump of a vehicle, the pump coupled to at least a power steering system and a power braking system is provided. The method comprises measuring steering and braking information using a brake sensor and a steering sensor; and adjusting output of said hydraulic pump base

대표청구항 ▼

1. A method to control a hydraulic pump of a vehicle, the pump coupled to at least a power steering system and a power braking system, the method comprising: measuring steering and braking information using a brake sensor and a steering sensor; andadjusting an output speed of said hydraulic pump based on measured information from said sensors, the output speed of said hydraulic pump being a pump speed and the hydraulic pump driven by an electric motor;wherein adjusting the output speed includes increasing the pump speed as a vehicle speed and/or steering rate increases and a brake is activated, and decreasing the pump speed as the vehicle speed decreases and the brake is deactivated. 2. The method of claim 1 wherein the brake sensor measures a two-state brake pedal input. 3. The method of claim 1 wherein the brake sensor measures a brake pressure. 4. The method of claim 1 wherein the steering sensor measures a steering angle rate. 5. The method of claim 1 further comprising measuring the vehicle speed from a vehicle speed sensor, and adjusting said output speed of the pump based on said measured vehicle speed. 6. The method of claim 5 further comprising increasing the pump speed as the vehicle speed increases during a first condition, and decreasing the pump speed as the vehicle speed increases during a second condition. 7. A system for a vehicle having a power steering and a power brake system, comprising: a pump coupled to at least the power steering and the power brake system;a brake switch sensor configured to indicate activation and deactivation of a brake pedal of the brake system by a vehicle operator;a brake light coupled to and activated by the brake switch sensor;a hydraulic brake booster hydraulically coupled to the pump and mechanically coupled to the driver actuated brake pedal;a steering sensor coupled to the steering system;a vehicle speed sensor; anda control system configured to adjust output speed of the pump in response to said brake switch sensor, said steering sensor, and said vehicle speed sensor, the control system further configured to increase pump output speed in response to activation of a brake or increase in a steering angle rate, and decrease pump output speed in response to deactivation of the brake or decrease in the steering angle rate, where said increase in pump output speed is at a faster rate than said decrease in pump output speed. 8. A method, comprising: controlling an electric motor-driven hydraulic pump coupled to a vehicle's power steering system and power braking system; andadjusting output speed of said hydraulic pump by adjusting the electric motor based on driver braking actuation, steering angle, and vehicle speed, said adjusting including increasing the pump speed as the vehicle speed increases based on a first condition, and decreasing the pump speed as the vehicle speed increases based on a second condition. 9. A method to control a hydraulic pump of a vehicle, the pump coupled to at least a power steering system and a power braking system, the method comprising: measuring steering and braking information using a brake sensor and a steering sensor; andadjusting an output speed of said hydraulic pump based on measured information from said sensors, the output speed of said hydraulic pump being a pump speed and the hydraulic pump driven by an electric motor,wherein adjusting the output speed includes increasing the pump speed as a vehicle speed and/or steering rate increases and a brake is activated, and decreasing the pump speed as the vehicle speed decreases and the brake is deactivated, andwherein the increasing the pump speed further includes: increasing the pump speed at a first rate as the vehicle speed increases and the brake is activated;increasing the pump speed at a second, different from the first, rate as the steering rate increases and the brake is activated; andincreasing the pump speed at a third, different from the first and second, rate as the vehicle speed and steering rate increase and the brake is activated. 10. The method of claim 6 further comprising increasing the pump speed as the vehicle speed decreases during a third condition, and decreasing the pump speed as the vehicle speed decreases during a fourth condition.
