摘要： A motor vehicle is provided with a driving status discrimination device, which includes a steering angle sensor for detecting the rotational angle of a steering wheel and a microcomputer for reading and processing the steering angle signal each time the vehicle runs a predetermined distance. The microcomputer identifies one of steering angular ranges of intervals to which each detected steering angle belongs so as to record the frequency at which the steering wheel was turned to each steering angular interval. The microcomputer modifies the frequency for each steering angle interval with a weighting coefficient determined for the steering angular interval and then, calculates a total or integrated value of the modified frequencies for the steering angular intervals. Further, the microcomputer discriminates town street driving from mountain road driving based upon the integrated value so that the assisting power generated by a power steering mechanism of the motor vehicle can be controlled based upon the result of such discrimination.

摘要： An apparatus for controlling the ratio of a assisting force produced by a power steering system installed in an vehicle to a steering torque supplied by the driver wherein the ratio is changed by a solenoid valve arranged in the power steering system. The CPU of the apparatus changes control current to be applied to the solenoid valve using a characteristic map defining change of a base current with respect to changes of the vehicle speed and the steering angle. Further, the CPU increases the control current, when the steering wheel is returned to its neutral angle position, so as to decrease the ratio, increasing the self returning ability of the steering mechanism. The control current applied to the solenoid valve during the returning operation is changed depending upon both the steering angle and the steering speed of the steering wheel using additional characteristic maps.

摘要： 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： In a feed control system, a feed controller controls a servomotor in such a manner as to reduce the difference between an objective position and a present position of a movable body. An interference detection circuit coupled to the feed controller detects the occurrence of an interference between the movable body and an obstruction when feed movement of the movable body is discontinued nevertheless the difference between the objection and present positions does not reach zero. A digital computer is coupled to an objective position counter provided in the feed controller to selectively set therein objective positions to which the movable body is to be positioned successively. The digital computer, when receiving a signal from the interference detection circuit, sets the objective position counter with data for moving the movable body a predetermined amount in a direction opposite to that wherein the movable body was moved before the occurrence of an interference.
