Application Number: JP,2023-061166
Category (FI): B60W30/12,B62D6/00,B62D119:00,B62D101:00
Stage: PROBLEM TO BE SOLVED: To provide a travel control device of a vehicle and travel control method which are improved so as to be able to determine whether or not to cease travel control of a vehicle without causing unnecessary stop of travel control of the vehicle and delay in the stopping determination of the travel control of the vehicle when the vehicle travels at a curve.SOLUTION: In a travel control device 100 which includes a traffic lane information acquisition device 12 and a control unit which controls an automatic steering device 46. The control unit calculates a target steering angle which defines a lateral position of a vehicle 102 as a target position with respect to a traffic lane and which performs travel control of controlling the automatic steering device so that a steering angle is the target steering angle. The control unit calculates a curvature factor of the traffic lane on the basis of traffic lane information and calculates estimated lateral acceleration of the vehicle on the basis of the curvature factor of the traffic lane and acquires superelevation of the traffic lane in front of the vehicle and calculates estimated superelevation lateral acceleration on the basis of the superelevation of the traffic lane and, when the estimated lateral acceleration of the vehicle which subtracts and corrects at the estimated superelevation lateral acceleration exceeds a reference value, the control unit does not perform the travel control of the vehicle.SELECTED DRAWING: Figure 1 (Grant)
