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.

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.

A driving support apparatus of a vehicle supports driving of the vehicle, the vehicle includes a rudder angle varying device capable of changing a relative relation between a steering angle and a rudder angle. The driving support apparatus includes a following control device for controlling the rudder angle varying device such that the vehicle follows a target driving route; a steering angle specifying device for specifying the steering angle; and a judging device for judging whether or not overriding performed by a driver takes place on the basis of the specified steering angle and a reference steering angle which is the steering angle in making the vehicle follow the target driving route. The following control device stops the vehicle following for the target driving route if it is judged that the overriding takes place.
摘要:
An object of the present invention is to cover a drop in turning responsiveness of a vehicle to a driver's steering operation caused by a limit on the operating speed of a steerable wheel turning unit by a turn assist yaw moment independent of turn lateral forces of steerable wheels to thereby prevent the drop in turning responsiveness of the vehicle when the operating speed of the steerable wheel turning unit is limited. A vehicle travel control device comprises a steerable wheel turning unit capable of turning steerable wheels to steer independently of steering of a driver and a braking unit as a turn assist yaw moment generating means capable of generating a turn assist yaw moment independently of turn lateral forces of the steerable wheels. When a predetermined controlled variable limiting condition is established and the controlled variable of the steerable wheel turning unit is limited, the influence of limiting the controlled variable of the steerable wheel turning unit on the turn yaw moment of the vehicle can be reduced by changing braking forces of individual wheels and generating a yaw moment by differences in braking force between left and right wheels.
