摘要： A power steering apparatus has a steering power assisting system coupled to tire wheels and a variable gear transfer system coupled to a steering wheel. The steering power assisting system includes a torsion bar rotation sensor and a first actuator rotation sensor to calculate a first pinion angle and a second pinion angle based on the detected rotation angles, respectively. The variable gear transfer system includes a steering sensor and a second actuator rotation sensor to calculate a third pinion angle based on the detected rotation angles. Sensor failure is detected by comparing the calculated first, second and third pinion angles.

摘要： A vehicle drive-control device which executes trajectory control in which steered wheels are controlled so as to make the vehicle travel along a target trajectory. When the possibility exists that the travel direction of the vehicle may be changed by the trajectory control, at least one of an operation position of a steering input unit operated by a driver; a yaw angle of the vehicle; and a lateral position of the vehicle with respect to a lane is changed before a change in the travel direction is made, thereby giving occupants in the vehicle advance notice of the possibility of a change in vehicle travel direction caused by the trajectory control.
