Vehicle speed control device
A vehicle speed control device 1 includes a lane detection unit 120 configured to detect a road outside line of a lane on which a host vehicle V is traveling, a target detection unit 121 configured to detect a target that is present outside the road outside line, and a speed control unit 123 configured to control a speed of the host vehicle V such that the host vehicle V passes a lateral side of the target at a speed lower than a speed of the host vehicle V when the target has been detected. After the host vehicle V has passed the lateral side of the target, the speed control unit 123 accelerates the host vehicle V up to the speed when the target has been detected.
1. A vehicle speed control device comprising:
a controller configured to:
detect a road outside line of a lane on which a host vehicle is traveling;
detect a target that is present outside the road outside line; and
control a speed of the host vehicle such that the host vehicle passes a lateral side of the target at a speed lower than a speed of the host vehicle when the target has been detected,
wherein the controller is configured to control the speed of the host vehicle such that the host vehicle decelerates to a predetermined speed lower than the speed of the host vehicle when the target has been detected, the predetermined speed being set by a rate with respect to the speed of the host vehicle when the target has been detected, and
wherein the rate with respect to the speed of the host vehicle, when the target vehicle is detected, is set such that the controller increases a deceleration amount of the host vehicle as the speed of the host vehicle e, when the target vehicle is detected, increases.
2. The vehicle speed control device according to claim 1 ,
wherein, after the host vehicle has passed the lateral side of the target, the controller accelerates the host vehicle up to the speed when the target has been detected.
3. The vehicle speed control device according to claim 1 ,
wherein the controller limits accelerating of the host vehicle in a case where a distance between the host vehicle and the target is within a predetermined range.
4. The vehicle speed control device according to claim 1 ,
wherein the controller is further configured to:
notify decelerating of the host vehicle in a case where the target has been detected.
5. The vehicle speed control device according to claim 1 ,
wherein the controller is further configured to:
detect a following vehicle traveling behind the host vehicle, and
wherein when the following vehicle has been detected, the controller does not decelerate the host vehicle even when the target has been detected.
