    摘要: An electric power steering apparatus comprises a control unit which controls a motor drive for driving an electric motor on the basis of an steering torque signal. The control unit has an assist inhibitor for inhibiting the feed of an assist torque by the motor to a steering system under given conditions. The assist inhibitor inhibits the generation of the assist torque by the motor when the direction of a manual steering torque and the direction of the assit torque are inconsistent for more than a predetermined time period. As a result, it becomes possible to exhibit desired damper effect during the predetermined time period and to inhibit the feed of the assist torque by the motor to the steering system after lapsing of the predetermined time period.

    摘要: An electric power steering apparatus for a vehicle includes a protection circuit for stopping operation of an electric motor provided to apply a steering assist force to a steering system of the vehicle. The protection circuit is operable to stop operation of the electric motor when an ignition off signal is supplied from an ignition sensor and at least one of an engine speed signal supplied from an engine speed sensor and a vehicle velocity signal supplied from a vehicle velocity sensor falls below a corresponding predetermined value. Even if an ignition on signal is not supplied during movement of the vehicle due to a failure in the ignition sensor, when the engine speed signal or the vehicle velocity signal is above the predetermined value, the vehicle is regarded as being in the running state and operation of the electric motor is continued to apply the steering assist force to the steering system. With this arrangement, a good and stable steering feel can be obtained during movement of the vehicle.

    摘要: A vehicular motor driving apparatus includes a control unit 15 for drive-controlling a motor by PWM-drive-controlling a motor driving circuit based on a motor starting signal. The control unit has a drive controller for setting a drive frequency of a PWM-drive control signal to be an integral multiple of or (integer+0.5) times a channel frequency interval of channel frequencies allotted for AM radio broadcasts. As a result, radiation noise associated with harmonics of the PWM-drive control signal, when coincided with the channel frequencies used by AM radio broadcast stations, is removed along with the channel frequencies through radio receiver detection. When the radiation noise does not coincide with the in-use channel frequencies, it is offset by the channel frequency interval therefrom, thereby preventing its reception.

    摘要: An electric power steering apparatus, which provides a steering assist of an electric motor directly to a vehicle steering system to reduce necessary steering power to be applied by a vehicle driver, is provided with a control unit which includes a proportion-coefficient and integration-coefficient setting section for, on the basis of a velocity of the vehicle detected by a velocity sensor, setting sensitivity of a proportioning element and integration gain of an integrating element in such a manner that they take greater values during high-velocity running of the vehicle than during low-velocity running of vehicle. This prevents occurrence of unwanted noises and vibrations during low-velocity running of the vehicle and also enhances steering response during high-velocity running of the vehicle, thus always providing an optimum steering feeling in changing running conditions of the vehicle. The control unit may further include a compensation section provided between an offset calculation section and a proportional and integral control section for, on the basis of the velocity detected by the velocity sensor, modifying the offset signal in such a manner that the offset signal takes a greater value during high-velocity running of the vehicle than during low-velocity running of vehicle.

    摘要: In an hydraulic active vehicle suspension system using a linear hydraulic cylinder as a primary actuator, controlled hydraulic pressure is supplied to an upper chamber of the hydraulic cylinder defined by a smaller pressure receiving surface of the piston and the cylinder while a reduced and fixed pressure is supplied to a lower chamber of the hydraulic cylinder defined by a larger pressure receiving surface of the piston and the cylinder, and an accumulator is connected to the lower chamber so that a desired hydraulic actuation can be accomplished by the controlled hydraulic pressure while sudden forces or inputs containing high frequency components applied to the lower chamber are absorbed by the accumulator. Thus, the accumulator offers a favorable response to the wheel riding over a bump or otherwise experiencing sudden movements and the absence of any accumulator connected to the upper chamber ensures a high speed response property of the system without requiring a large power capacity of the pump serving as the pressure source for the system.

    摘要: A motor vehicle such as a four-wheel drive vehicle having a first axle shaft which is driven by a drive source and a second axle shaft which is driven by the same drive source, each of a pair of wheels associated with the second axle shaft being powered by way of individual variable torque transmitting devices, further comprising: a steering condition sensor; and a control unit which reduces a torque transmission ratio of one of the variable torque transmitting devices corresponding to the inner one of the wheels of the second axle shaft when the steering condition sensor has detected a steering angle greater than a prescribed value. Thereby, the problem of the tight turn braking can be avoided without losing the advantages of four-wheel drive. Other driving conditions such as braking and acceleration as well as an excessive temperature increase in each of the variable torque transmitting devices may be taken into consideration in carrying out the control of the variable torque transmitting devices which preferably consist of viscous couplings. Each of the viscous couplings is provided with means for externally varying the torque transmission ratio thereof and transmits torque between input and output thereof at a level which is substantially proportional to the speed difference between input and output thereof.
