There is disclosed an apparatus for controlling the ratio of the assisting force produced by a power-steering system installed in an automobile to the steering torque supplied by the driver. The apparatus primarily consists of a microprocessor, a ROM, and a RAM. The microprocessor controls the amount of current supplied to a solenoid valve according to the velocity of the automobile. The aforementioned ratio is varied according to the driver's condition and the road condition. Four graphs representing the relation of the electric current supplied to the solenoid valve to the angle through which the steering wheel is rotated are stored in the ROM. Each graph has two characteristic curves for two different values of the velosity of the automobile. The microprocessor calculates a driver's condition index from the output signal from a velocity sensor. Also, it calculates a road condition index from the output signal from a steering angle sensor. The value of the current supplied to the solenoid valve is selected from the data stored in the ROM according to these indices.
摘要:
An electronically controlled power steering apparatus wherein the steering force generated by a power cylinder (15) is controlled by a microcomputer (54). Detection signals from a vehicle speed sensor (50) and a steering angle sensor (51) are input to the microcomputer (54), which thus, reads out from a memory (60) stored control electric currents corresponding to detection signals in order to output the appropriate control electric currents. A solenoid valve (20) for controlling the communication between left and right chambers of the power cylinder (15) and another solenoid valve (30) for controlling the supply of pressurized fluid from a pump (16) to a servovalve (14) are driven in response to the control electric currents from the microcomputer (54). When the vehicle runs a predetermined distance or a predetermined time period after the supply of electric current, the microcomputer (54) decreases the control electric currents charged to the solenoid valves (20) and (30). Accordingly, even in a vehicle of the type wherein a neutral position of the steering (10 ) cannot be precisely detected unless the vehicle runs the predetermined distance or the predetermined time period after the supply of electric power, any uncomfortable or strange "feel" by the driver can be avoided.

摘要:
A solenoid-operated valve particularly for use in a speed-responsive power steering system on a motor vehicle comprises a valve housing having two ports opening into a bore in the housing, a spool axially slidable in the bore and slot defining a bypass passageway extending between the two ports and variable in cross section upon axial movement of the spool. The spool is spring-biased in a direction to close the bypass passageway, but attractable by an energized solenoid to open the bypass passageway when the solenoid is supplied with an electric current dependent on the speed of travel of the vehicle. The spool has therein a restrictor disposed in the bypass passageway adjacent to the slot to restrict the flow of a fluid through the bypass passageway into and out of the bore in the housing. The restrictor develops a pressure drop while the fluid flows through the bypass passageway to maintain the spool substantially in equilibrium while the fluid under pressure flows through the bypass passageway in either direction upon axial shifting of the spool. The solenoid-operated valve enables dirigible wheels to be assisted in getting turned to the right or left by equal or balanced steering forces generated by the power steering system.
摘要:
A steering force control device for a power steering device, wherein various inputs including input and output torques respectively applied to and generated by the power steering device are detected and input to a digital computer. The computer selects one of plural objective output torque values stored in a memory device based upon the various inputs except for the output torque and then, calculates a control output value based upon the detected output torque and the selected objective output torque. The calculated control output value is applied to a linear solenoid valve which is provided in a fluid system of the power steering device, whereby the output torque generated by the power steering device is controlled to follow the selected of the objective output torques.
