Abstract
The invention discloses an electric hydraulic steering system used for a passenger car, and the system provided by the invention comprises a hydraulic steering gear and is characterized by also comprising a car speed sensor, a microprocessor, an electric control device and an electric control bypass valve, wherein the microprocessor is used for calculating a target value of the opening degree of the electric control bypass valve according to a car speed signal sent by the car speed sensor and driving an electric control device on the electric control bypass valve to enable the opening degree of the electric control bypass valve to reach the preset target value. In the electric hydraulic steering system used for the passenger car provided by the invention, an electric control unit is used for collecting the car speed signal and controlling the flow rate of the electric hydraulic steering system, thereby achieving the purpose of changing an input torque, acquiring suitable input output features, enhancing the convenience in pivot steering and low-speed running of the passenger car and enhancing the stability of high-speed running.
Description
Technical field
The present invention relates to a kind of passenger vehicle electricity consumption liquid steering swivel system.
Background technology
Existing passenger vehicle steering swivel system all is the mechanical-hydraulic power steering system, the defective that exists is: the flow control by automobile steering device is just realized according to engine speed change by steering pump, and often have a lot of influence factors between the rotating speed of driving engine and the actual vehicle speed, and the variation between them neither be linear.But a principal parameter that influences the passenger vehicle steering swivel system is the speed of a motor vehicle, is not engine speed.
Summary of the invention
The present invention seeks to: provide a kind of by the sensor sensing vehicle speed signal, come control policy according to vehicle speed signal, calculate the expected value of bypass disc aperture, and the electrical controller on the driving bypass disc makes the bypass disc aperture reach predetermined target value, the hydraulic booster characteristic of bypass control valve (BCV) decision main valve, thereby the passenger vehicle electricity consumption liquid steering swivel system of the input torque on the decision bearing circle.
Technical scheme of the present invention is: a kind of passenger vehicle electricity consumption liquid steering swivel system, comprise hydraulic power steering device, it is characterized in that, also comprise car speed sensor, microprocessor, electrical controller and automatically controlled bypass disc, the vehicle speed signal that described microprocessor sends according to described car speed sensor calculates the expected value of bypass disc aperture, and the electrical controller that drives on the bypass disc makes the bypass disc aperture reach predetermined target value.
Further, described microprocessor is the ECU of passenger vehicle.
Advantage of the present invention is:
1. native system is simple in structure, and is safe and reliable, when the electric system et out of order, can guarantee the input-output characteristic of the common hydraulic power steering device of system held.
Guaranteed the portability that automobile turns to when the low speed driving and stability when running at high speed based on the cornering properties of speed responsive, in addition, guarantee that under any speed of a motor vehicle the oil pressure of work and flow all can reach maxim, can resist unexpected automatic steering, make to turn to accurately, safer.
Description of drawings
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a passenger vehicle electricity consumption liquid steering swivel system scheme drawing of the present invention.
The specific embodiment
Embodiment: passenger vehicle electricity consumption liquid steering swivel system as shown in Figure 1 comprises hydraulic power steering device (HPS), car speed sensor, microprocessor, electrical controller and automatically controlled bypass disc, the vehicle speed signal that microprocessor sends according to car speed sensor calculates the expected value of bypass disc aperture, and the electrical controller that drives on the bypass disc makes the bypass disc aperture reach predetermined target value.In the present embodiment, microprocessor adopts the ECU on the car.During mode of operation, by the sensor sensing vehicle speed signal, vehicle speed signal is sent to ECU and handles, calculate the expected value of bypass disc aperture, and the electrical controller on the driving bypass disc makes the bypass disc aperture reach predetermined target value, the hydraulic booster characteristic of bypass control valve (BCV) decision main valve, thereby the input torque on the decision bearing circle.Passenger vehicle electricity consumption liquid steering swivel system of the present invention is simple in structure, has increased ECU (Electrical Control Unit) and automatically controlled bypass disc on former mechanical-hydraulic power steering system.Passenger vehicle electricity consumption liquid steering swivel system of the present invention is crossed ECU (Electrical Control Unit) and is gathered vehicle speed signal, and the flow of steering swivel system controlled, thereby reach the purpose that changes input torque, obtain suitable input-output characteristic, the stability that improves automobile pivot stud and low-tach portability and run at high speed.
Above embodiment only is the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Claims (2)
1. passenger vehicle electricity consumption liquid steering swivel system, comprise hydraulic power steering device, it is characterized in that, also comprise car speed sensor, microprocessor, electrical controller and automatically controlled bypass disc, the vehicle speed signal that described microprocessor sends according to described car speed sensor calculates the expected value of bypass disc aperture, and the electrical controller that drives on the bypass disc makes the bypass disc aperture reach predetermined target value.
2. passenger vehicle electricity consumption liquid steering swivel system according to claim 1 is characterized in that described microprocessor is the ECU of passenger vehicle.
