摘要： A signal processor comprises wheel speed-detecting means for detecting a wheel speed signal including vibrational components of a tire, extraction means for extracting a resonant frequency of the vibrational components of the tire or a tire spring constant based on the wheel speed signals, air pressure-estimating means for estimating a tire air pressure based on the resonant frequency or the tire spring constant, and determining means for determining whether the estimated tire air pressure is abnormal or not by comparing with a determination value. Further, correcting means corrects at least one of the determination value, the estimated tire air pressure, the resonant frequency and the tire spring constant in response to a tire temperature. A temperature-sensing device is mounted inside the signal processor to detect a temperature associated with the tire temperature.

摘要： In a steering control apparatus, a worm gear is configured to have a lead angle for a self-lock operation, by which a worm wheel is allowed to rotate by rotation of a worm but the worm is not allowed to rotate by rotation of the worm wheel. Thus, a lock mechanism need not be provided separately from a gear mechanism and the apparatus is reduced in entire size. A VGRS control part checks whether the worm gear has a self-lock failure, which disables the self-lock operation. If the worm gear has the self-lock failure, idling suppression processing is performed to suppress idling of a steering wheel. Thus, even when the self-lock failure arises, the steering wheel is suppressed from idling.

摘要： A vehicle height sensor includes switching circuits which are turned on and off in accordance with height of a vehicle. The vehicle height sensor is driven when a drive signal is outputted to the sensor. A preset voltage is fed to terminals of the respective switching circuits via resistors. Voltages at the terminals are outputted as vehicle height data having bits corresponding to the respective switching circuits. When the output of the drive signal is suspended, the vehicle height data are read as vehicle height sensor malfunction detecting data. The malfunction detecting data are compared to preset reference data. The vehicle height sensor is judged to be wrong when the malfunction detecting data differ from the preset reference data.

摘要： A VGRS device checks whether assist control of an EPS device for assisting steering operation of a steering wheel is being stopped. If the assist control of the EPS device is being stopped, a speed increase ratio is determined so that the rotation angle of the output shaft is less than the rotation angle of the input shaft. A VGRS motor is controlled and driven based on a determined speed increase ratio. Thus, steering operation of the steering wheel can be controlled appropriately so that the steering operation of the steering wheel can be continued with relatively small torque. It is less likely that a driver will erroneously feel that the steering wheel is locked.

摘要： An electronic circuit including semiconductor modules and capacitors is positioned in the axial direction of a motor. Each semiconductor module is longitudinally positioned in contact with a heat sink. More specifically, a line perpendicular to the surface of a semiconductor chip included in the semiconductor module is perpendicular to the axis line of the motor. Consequently, each capacitor is positioned so that at least a part of the positional range of the capacitor in the axial direction of the motor coincides with the positional ranges of the semiconductor module and the heat sink in the axial direction.

摘要： A V1 semiconductor module has a coil terminal, which is directly connectable to a lead wire of a coil. As a result, the number of parts required to connect electronic parts is reduced. Further, since no printed circuit board is required, the coil terminal can be shaped in any size without being limited in correspondence to the thickness of a copper film of the substrate. The coil terminal and control terminals, which are connected to the printed circuit board having a control circuit for controlling current supply to the coil, are provided on different wall surfaces of a resin part. Thus, the coil and the printed circuit board can be readily connected to the coil terminal and the control terminals, respectively, resulting in simplification of the device.
