Traveling control system and control method of vehicle
A traveling control system comprises: a detection unit that detects another vehicle traveling in the periphery and peripheral environmental information; an acquisition unit that acquires, based on detected information, a range of a lane on which a self-vehicle travels; a first determination unit that determines, based on the detected information, approach of the other vehicle traveling in the periphery to the acquired lane, on which the self-vehicle travels; and a control unit that performs traveling control to increase a distance between the self-vehicle and the other vehicle if it is determined by the first determination unit that the approach by the other vehicle is made, wherein as the traveling control, the control unit moves a traveling position of the self-vehicle in a lateral direction different from a side of the other vehicle.
1. A traveling control system comprising:
a sensor configured to detect another vehicle traveling in the periphery and peripheral environmental information; and
a controller including at least one processor and at least one storage device, and configured to:
acquire, based on information detected by the sensor, a range of a lane on which a self-vehicle travels;
determine, based on the information detected by the sensor, approach of the other vehicle traveling in the periphery to the lane on which the self-vehicle travels;
determine, based on the information detected by the sensor, whether a state of a road surface is a snow accumulation state;
acquire, based on the information detected by the sensor, a range of snow swirling caused by the approach of the other vehicle if it is determined that the other vehicle traveling in the periphery approaches the lane on which the self-vehicle travels and the state of the road surface is the snow accumulate state; and
move a traveling position of the self-vehicle in a lateral direction different from a side of the other vehicle so as to increase a distance between the self-vehicle and the other vehicle with a control amount in accordance with the range of the snow swirling if it is determined that the other vehicle traveling in the periphery approaches the lane on which the self-vehicle travels and the state of the road surface is the snow accumulate state.
2. The traveling control system according to claim 1 , wherein the larger the range of the snow swirling, the larger the controller makes the control amount.
3. The traveling control system according to claim 1 , wherein the controller is configured to acquire, based on the information detected by the sensor, a range of a wheel track formed in the lane on which the self-vehicle travels, and
the controller is configured to decide the control amount so as to perform the traveling control within the range of the wheel track.
4. A control method of a vehicle including a sensor configured to detect another vehicle traveling in the periphery and peripheral environmental information, comprising:
an acquisition step of acquiring, based on information detected by the sensor, a range of a lane on which a self-vehicle travels;
a determination step of determining, based on the information detected by the sensor, approach of the other vehicle traveling in the periphery to the lane acquired in the acquisition step, on which the self-vehicle travels;
a determination step of determining, based on the information detected by the sensor, whether a state of a road surface is a snow accumulation state;
an acquisition step of acquiring, based on the information detected by the sensor, a range of snow swirling caused by the approach of the other vehicle if it is determined that the other vehicle traveling in the periphery approaches the lane on which the self-vehicle travels and the state of the road surface is the snow accumulate state; and
a control step of performing traveling control to move a traveling position of the self-vehicle in a lateral direction different from a side of the other vehicle so as to increase a distance between the self-vehicle and the other vehicle with a control amount in accordance with the range of the snow swirling if it is determined that the other vehicle traveling in the periphery approaches the lane on which the self-vehicle travels and the state of the road surface is the snow accumulate state.
