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.

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.
