POWER-ASSISTED STEERING SYSTEM

摘要

The invention concerns a power-assisted steering system with a servo valve (6), open at the centre, designed to supply an actuator element (1) with hydraulic pressure, and with a pump (7) driven by an electric motor (13) to supply the servo valve (6) with hydraulic fluid, the power consumption of the electric motor being controlled by an electronic unit (21) as a result of the comparison of operating parameters monitored by sensors. The invention proposes that the sensors are connected to a control unit having at least one microprocessor, the control unit defining reference values as a function of the operating parameters monitored.
