摘要： A vehicle steering apparatus having a variable gear ratio unit arranged midway along a steering transmission system for connecting a steering wheel and a tire to change a transmission ratio upon driving a motor includes a connecting unit for stopping actuation of the variable gear ratio unit in accordance with an external signal to connect the input side of the variable gear ratio unit which is connected to the steering wheel to the output side of the variable gear ratio unit which is connected to the tire. Even if a reverse input acts from a tire side during traveling, the relationship between the steering amount of the steering wheel and the turning amount of the tire can be kept unchanged.

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： 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.
