    摘要: An electrohydraulic steer-by-wire steering system has an operator interface for specifying a turning angle, which is associated with a sensor for the acquisition of a position or movement of the operator interface. An electronic control device is connected to a first electrohydraulic circuit and to a second electrohydraulic circuit and set up in order to actuate the two electrohydraulic circuits as a function of a signal from the sensor. The system further includes a steering actuator for adjusting the turning angle of a steerable wheel. The steering actuator has two chambers each of which is connected simultaneously to the two electrohydraulic circuits.

    摘要: An electric actuator-integrated electric power steering system may include an integrated motor which provides rotational force, a hydraulic pump connected to one end of the integrated motor and supplied with the rotational force from the integrated motor to pump working fluid that is used to transmit steering force, and an electric actuator connected to the other end of the integrated motor via a power controlling means. The electric actuator may operate when the rotational force is transmitted to the electric actuator and whether the rotational force from the integrated motor is transmitted to or cut off from the electric actuator may depend on an operation of the power controlling means.

    摘要: Power steering system including: an electric pump to supply fluid to a power steering unit; and an engine control unit (ECU) to control an amount of the fluid by a rotation speed of the electric pump. The ECU includes a first device for calculating an on-slope standby rotation speed and setting the electric pump to this speed when a vehicle is descending or ascending a slope. This speed is calculated by correcting a standby rotation speed of the electric pump corresponding to a vehicle speed with a slope correction value calculated according to a slope angle or a vehicle body angle. Accordingly, it is possible to supply the fluid with the electric pump and assist a steering operation to suppress both a jerky steering feeling due to insufficient steering force in slope descent and a lack of response in the steering operation due to excessive steering force in slope ascent.
