Abstract

In a vehicle control device, detection of an object around a vehicle is performed, in a case where it is determined that there is a possibility that the vehicle may collide with the object, whether or not a collision can be avoided by braking control of the vehicle is determined, and in a case where it is determined that a collision cannot be avoided by the braking control, steering and braking control to avoid a collision by both steering of the vehicle and braking of the vehicle is performed, flashing of a direction indicator is started, and in a case where the vehicle has stopped, flashing of hazard flashing indicators is performed.

Claims

an object detection unit configured to detect an object around a vehicle;

a collision determination unit configured to determine whether or not there is a possibility that the vehicle may collide with the object detected by the object detection unit;

a braking avoidance determination unit configured to determine whether or not a collision can be avoided by braking control of the vehicle, based on a detection result of the object detection unit and a vehicle speed of the vehicle, in a case where a determination that there is a possibility that the vehicle may collide with the object is made by the collision determination unit;

a driving control unit configured to perform the braking control without the steering control in a case where a determination that the collision can be avoided by the braking control is made by the braking avoidance determination unit, and to perform steering and braking control to avoid the collision by both steering of the vehicle and braking of the vehicle, in a case where a determination that the collision cannot be avoided by the braking control is made by the braking avoidance determination unit; and

wherein the driving control unit is configured to perform the steering and braking control in accordance with the target pathway.

3. The vehicle control device according to claim 1, further comprising:

a display control unit configured to cause steering display corresponding to a steering direction of the steering and braking control by the driving control unit to be displayed on a display in the vehicle in a case where a determination that the collision cannot be avoided by the braking control is made by the braking avoidance determination unit.

4. A vehicle control device comprising:

a detector configured to detect an object around a vehicle; and

an electronic control unit (ECU) programmed to;

determine whether or not there is a possibility that the vehicle may collide with the object detected by the detector;
