摘要： A PWM control includes a first PWM control and a second PWM control. In the first PWM control, a first power supply terminal of a first coil is kept non-switched under being connected to a first pole of a direct current power source, and a second power supply terminal of a second coil is capable of being switched under being connected to a second pole of the direct current power source. The second PWM control is performed by switching a first connected condition and a second connected condition by turns. The first connected condition is established with the first power supply terminal connected to the first pole and the second power supply terminal connected to the second pole. The second connected condition is established with the first power supply terminal being connected to the second pole and the second power supply terminal being connected to the first pole.

摘要： An electric steering control device is provided which is capable of enabling the driver to perform steering manipulation stably without being substantially affected by the ambient temperature and the heat generation of the control device. The control device comprises a temperature sensor for detecting the temperature of a circuit board mounting a motor drive circuit thereon and a compensation section for compensating an electric current command value based on the board temperature detected by the temperature sensor, so that en electric motor for exerting an assist force on a vehicle steering mechanism is driven by the compensated electric current command value output from a motor drive circuit. Therefore, the steering operation can be done stably without being substantially affected by the ambient temperature and the heat generation of the control device. In particular, since the temperature sensor is arranged not on the motor drive circuit per se but on a circuit board mounting the motor drive circuit thereon, the freedom can be heightened in arranging the temperature sensor. Further, since the temperature sensor for heat control of a spiral cable provided on the electric motor is utilized also for compensation of the electric current command value, the components for the control device can be reduced in number.

摘要： A vehicular steering control apparatus controls the wheel steering amount of wheels based on a steering angle and an assist angle obtained by multiplying a steering speed by a gain. If the amount of power control differs between the left wheel and the right wheel, the value of gain is increased. The amount of power control includes, for example, the amount of braking control and the amount of drive control. If the assist angle is increased by increasing the gain, the magnitude of the wheel steering amount relative to the steering angle increases, so that a driver can correct the orientation of the vehicle body by performing a small amount of steering operation.

摘要： A vehicle steering apparatus includes a variable gear ratio mechanism which is provided in a steering force transmitting system, and a lock mechanism which restricts relative rotation of an input shaft and an output shaft of the transmitting ratio changing mechanism. The lock mechanism is engaged by inserting a lock arm in a indented portion of a lock holder of the lock mechanism. A play angle when the lock mechanism is engaged by inserting the lock arm in the indented portion is set to be smaller than a rotational angle of a motor which is required for outputting six different signals.

摘要： A angle sensor 103 identifies a angle phase of a rotatable member based on a kind of an identified pattern of the angle phase to detect an angular position of a steering shaft driven by a motor 6. A steering controller 100 identifies a rotational direction based on an identified pattern output of the angle and performs a sampling of the pattern output at a predetermined interval, identifies an order of combination order of the identified pattern of an angle phase in a first sampling and a second sampling following to the first sampling, and determines a pattern exchange number with the rotational direction from the order in the first sampling to the order in the second sampling. The steering controller 100 adds a number corresponding to the pattern exchange number to a counting number when the rotational direction is plus and decrease a number corresponding to the pattern exchange number from the counting number when the rotational direction is minus in order to identify the angular position of the steering shaft by the counted number.

摘要： A target relative rotational angle Δθt which is created by a steering gear ratio change unit and which is formed by a lower steering shaft relative to an upper steering shaft is calculated on the basis of a steering angle θ, and a post-correction target relative rotational angle Δθta to be created by the steering gear ratio change unit is calculated on the basis of the target relative rotational angle Δθt and a vehicle speed range that has been determined on the basis of a vehicle speed V. Thus, a target relative rotational angle in one lateral direction is so corrected as to be equal to or smaller than a difference between a permissible rotational angle to be defined by a spiral cable in the other lateral direction and a maximum possible rotational angle of the lower steering shaft in the other lateral direction. An electric motor is controlled on the basis of the post-correction target relative rotational angle Δθta.
