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： Provided is a vehicle cruise control device 10 that performs trajectory control for causing a vehicle to travel along a traveling road by steering vehicle wheels. The vehicle cruise control device includes: a roll control device (active stabilizers 56 and 58, etc.) configured to control a lateral-direction inclination angle of a vehicle body; and an inclination angle estimation device (a roll rate sensor 72, a stroke sensor 74i, etc.) configured to determine a lateral-direction inclination of a traveling road. When the trajectory control is executed in a situation in which the vehicle travels on a laterally inclined traveling road (S150, S250, S300, S500), the lateral-direction inclination angle of the vehicle body is controlled by the roll control device so that the lateral-direction inclination angle of the vehicle body is greater than 0 and smaller than the lateral-direction inclination angle of the traveling road (S450).

摘要： Lane keeping control is ended in accurate timing which does not give an uncomfortable feeling to a driver. In a vehicle 10 which is provided with a steering mechanism 200, an EPS actuator 300, and a VGRS actuator 500 and which can change a rudder angle regardless of a driver's steering input due to the cooperative control of the aforementioned mechanism and actuators, an ECU 100 performs LKA end control. In the control, in cases where a winker lever 16 is operated in a period of performing LKA control for making the vehicle 10 follow a target driving route, if the indicated direction of the winker lever 16 is different from a generation direction of generating an assist steering torque TA of the EPS actuator 300 in the LKA control, the LKA control is promptly ended. In cases where the indicated direction is equal to the generation direction, if a steering angle MAdrv corresponding to the driver's steering input exceeds a steering angle MAlka generated by the LKA control, the LKA control is ended.
