摘要： An electric power steering device is disclosed which comprises a fail-safe relay. The circuitry for operating the relay comprises the following: the neutral region detector circuit which generates an output when the steering torque applied by the operator is in the neutral region; a motor current detector circuit for detecting the motor current; an AND gate having inputs coupled to the above two circuits; a self-hold circuit for holding the output of the AND gate; and a relay interrupting circuit for interrupting the relay in response to the output of the self-hold circuit. Thus, the fail-safe relay is interrupted to disconnect the battery from the motor and clutch when the motor is energized in spite of the fact that the steering torque by the operator of the vehicle is in the neutral region.

摘要： An electric power steering apparatus for an automotive vehicle has an interrupter which cuts off the power to a drive motor when a dangerous situation is detected. In one form of the invention, the interrupter cuts off power to the drive motor when a ground fault sensor detects a ground fault of a motor driver and there is disagreement between a directional drive signal to the drive motor and the direction of torque applied to the steering wheel by the driver. In another form of the invention, the interrupter circuit cuts off power when the vehicle speed exceeds a prescribed level and the torque applied to the steering wheel exceeds a prescribed level for a certain length of time. In a third form of the invention, the interrupter cuts off power when the motor current exceeds a prescribed level and disagreement of directional signals is detected.

摘要： An electric power steering device having a clutch 25 for connecting and disconnecting the motor 14 to and from the steering shaft is disclosed, the control circuit of which comprises, in addition to a microcomputer 3, an additional analog direction determiner circuit 17, and a first and a second logical circuit. The first logical circuit consists of a pair of AND gates 20A, 20B generates a final right or left direction signal supplied to the motor driver circuit. The second logical circuit consists of a pair of exclusive OR gates 21A, 21B and an AND gate 22 and supplies a deenergization signal to the clutch driver when the directions determined by the microcomputer and the analog direction determiner circuit disagree. The direction determiner circuit includes: a first comparator 31 which outputs a right direction signal when the output voltage of the torque sensor exceeds a first reference level; and a second comparator 32 which outputs a left direction signal when the output voltage of the torque sensor is below a second reference level which is lower than the first level. These reference voltages, selected at upper and lower ends of the non-sensitive region, may be obtained by a voltage divider.

摘要： A motor-driven power steering system equipped with a control unit (9) which controls the turn of a DC motor (13) as an auxiliary steering force on the basis of a steering torque signal from a steering torque sensor (2) that detects the rotational force of a steering wheel (1) and on the basis of a vehicle-speed signal from a vehicle-speed sensor (10), and which turns an electromagnetic clutch (16) on or off in order to effectively or ineffectively control the rotational force of the DC motor (13) as the auxiliary steering force. Further provided is a fail-safe relay (91) having a normally open contact (91b) on a line for supplying power to the electromagnetic clutch (16). Under an abnormal condition such as breakage in the power source wiring, the electromagnetic clutch (16) is shut off because of no energization of the fail-safe relay (91), and no auxiliary steering force is applied by the DC motor (13).

摘要： In order to perform a vehicle speed control in a motor driven type power steering control device, a speed change point detection sensor is provided and an assist is added or removed according to a speed change point signal therefrom. Therefore, a construction of an input circuit and a control program become simple and a simple control unit can be used. Further, by inputting a speed change point other than those at which the assist is added, it is possible to easily determine a breakage of an input line for speed change point, resulting in a highly safe power steering.

摘要： An electric motor assisted power steering device for an automobile is disclosed which comprises a dupicate torque direction determination system. The power steering device comprises, in addition to a microcomputer for determining the amount and direction of the auxiliary torque which is to be provided by the electric motor, an analog direction determiner circuit for determining the direction of the auxiliary torque. The torque sensor outputs a voltage which is substantially in linear relationship with the steering torque applied by the operator. The direction determiner circuit includes: a first comparator which outputs a right direction signal when this output voltage of the torque sensor exceeds a first reference level; and a second comparator which outputs a left direction signal when the output voltage of the torque sensor is below a second reference level which is lower than the first level. These reference voltages, selected at upper and lower ends of the non-sensitive region, may be obtained by a voltage divider. The microcomputer determines, on the basis of the output of the torque sensor, the direction of the auxiliary torque and outputs a corresponding right or left direction signal. A first AND gate performs an AND operation on the two right direction signals outputted from the microcomputer and the analog circuit; a second AND gate performs an AND operation on the two left direction signals. The motor driver circuit controls the direction of the current supplied to the electric motor in accordance with the output of the first and the second AND gate.
