Abstract

A straddle type vehicle includes a setting unit configured to set a warning line along a boundary between a traveling lane of a self-vehicle and an oncoming lane, a warning unit configured to issue a warning if the self-vehicle has crossed the warning line, a detection unit configured to detect a difficult-to-travel region in the traveling lane, and a determination unit configured to determine whether it is difficult or possible for the self-vehicle to pass between the boundary and the difficult-to-travel region. If it is determined by the determination unit that it is difficult for the self-vehicle to pass, the setting unit changes a position of the warning line to a position shifted from the boundary toward the oncoming lane side.

First claim

What is claimed is:

1. A two-wheeled vehicle comprising:
a control circuit including at least one processor and at least one storage device and configured to set a warning line along a boundary line marked on a road between a traveling lane of a self-vehicle and an oncoming lane; and
a sensor configured to detect a difficult-to-travel region in the traveling lane,
wherein the control circuit is configured to determine whether it is difficult or possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, when the difficult-to-travel region is detected by the sensor,
if it is determined that it is difficult for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit changes a position of the warning line along the boundary line marked on the road to a position shifted from the boundary line toward the oncoming lane side,
if it is determined that it is possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit does not change the position of the warning line along the boundary line marked on the road, and
wherein if the difficult-to-travel region is due to parking or stopping of a vehicle in the traveling lane, it is determined whether it is difficult or possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, based on a type of the parked or stopped vehicle in the traveling lane.

2. A two-wheeled vehicle comprising:
a control circuit including at least one processor and at least one storage device and configured to set a warning line along a boundary line marked on a road between a traveling lane of a self-vehicle and an oncoming lane;
a warning device including a display and configured to issue a warning to a rider of the self-vehicle if the self-vehicle has crossed the warning line; and
a sensor configured to detect a difficult-to-travel region in the traveling lane and another vehicle traveling in the oncoming lane,
wherein the control circuit is configured to determine whether it is difficult or possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, when the difficult-to-travel region is detected by the sensor,
if it is determined that it is difficult for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit changes a position of the warning line along the boundary line marked on the road to a position shifted from the boundary line toward the oncoming lane side,
if it is determined that it is possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit does not change the position of the warning line along the boundary line marked on the road regardless of whether or not the sensor detects the other vehicle in the oncoming lane, and
wherein if it is determined that it is possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, and the sensor detects the other vehicle in the oncoming lane, the warning device issues a warning even if the self-vehicle has not crossed the warning line.

3. The two-wheeled vehicle according to claim 2 ,
wherein if a distance between the boundary and the difficult-to-travel region is smaller than or equal to a predetermined distance, it is determined that it is difficult for the self-vehicle to pass.

4. The two-wheeled vehicle according to claim 2 , wherein the sensor is an image sensor and/or a radar.

5. A control apparatus for a two-wheeled vehicle, the apparatus comprising:
a control circuit including at least one processor and at least one storage device and configured to set a warning line along a boundary line marked on a road between a traveling lane of a self-vehicle and an oncoming lane; and
a sensor configured to detect a difficult-to-travel region in the traveling lane,
wherein the control circuit is configured to determine whether it is difficult or possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, when the difficult-to-travel region is detected by the sensor,
if it is determined that it is difficult for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit changes a position of the warning line along the boundary line marked on the road to a position shifted from the boundary line toward the oncoming lane side,
if it is determined that it is possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit does not change the position of the warning line along the boundary line marked on the road, and
wherein if the difficult-to-travel region is due to parking or stopping of a vehicle in the traveling lane, it is determined whether it is difficult or possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, based on a type of the parked or stopped vehicle in the traveling lane.

6. A control apparatus for a two-wheeled vehicle, the apparatus comprising:
a control circuit including at least one processor and at least one storage device and configured to set a warning line along a boundary line marked on a road between a traveling lane of a self-vehicle and an oncoming lane;
a warning device configured to issue a warning if the self-vehicle has crossed the warning line; and
a sensor configured to detect a difficult-to-travel region in the traveling lane and another vehicle traveling in the oncoming lane,
wherein the control circuit is configured to determine whether it is difficult or possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, when the difficult-to-travel region is detected by the sensor,
if it is determined that it is difficult for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit changes a position of the warning line along the boundary line marked on the road to a position shifted from the boundary line toward the oncoming lane side,
if it is determined that it is possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, the control circuit does not change the position of the warning line along the boundary line marked on the road regardless of whether or not the sensor detects the other vehicle in the oncoming lane, and
wherein if it is determined that it is possible for the self-vehicle to pass between the boundary line marked on the road and the difficult-to-travel region, and the sensor detects the other vehicle in the oncoming lane, the warning device issues a warning even if the self-vehicle has not crossed the warning line.
