Vehicle control device and storage medium
A control unit is provided for executing cruise control for causing a vehicle to travel while maintaining a set speed, and the control unit is a vehicle control device that determines whether or not there is a traffic factor affecting the cruise control on the basis of a detection value for detecting the surroundings of the vehicle in the cruise control for maintaining the set speed, and adjusts first acceleration set in the cruise control according to the content of the traffic factor when the traffic factor is present.
1 . A vehicle control device that controls a host vehicle to perform a cruise control that causes the host vehicle to maintain travel at a set speed, the vehicle control device comprising:
a processor configured to
acquire a detection value output from a sensor installed on the host vehicle, the sensor being configured to detect surroundings of the host vehicle; and
determine whether traffic factor that affects the cruise control is present based on the acquired detection value while the cruise control is performed, wherein
the processor adjusts a first acceleration that is set in the cruise control in response to determining that the traffic factor affects the cruise control, and
the traffic factor includes one or more of a lane width, a road curvature, or a road gradient associated with a road environment in which the vehicle is travelling.
2 . The vehicle control device according to claim 1 , wherein the processor is further configured to
adjust the first acceleration according to the density when the traffic factor indicates a density of traffic present around the host vehicle affects the cruise control.
3 . The vehicle control device according to claim 1 , wherein the processor is further configured to
adjust the first acceleration using a second acceleration as target acceleration when the traffic factor indicates a difference between the second acceleration and the first acceleration exceeds a reference value, the second acceleration being an acceleration of a second vehicle around the host vehicle while the second vehicle is traveling.
4 . The vehicle control device according to claim 1 , wherein the processor is further configured to
calculate an acceleration adjustment value based on the one or more properties of the lane width, the road curvature, or the road gradient associated with a road environment; and
multiplies the first acceleration by the acceleration adjustment value to calculate an adjusted first acceleration to be set in the cruise control.
5 . The vehicle control device according to claim 4 , wherein the processor is further configured to
increase the acceleration adjustment value as the lane width increases and reduce the acceleration adjustment value as the lane width decreases.
6 . The vehicle control device according to claim 4 , wherein the processor is further configured to
increase the acceleration adjustment value as the road curvature increases and reduce the acceleration adjustment value as the road curvature decreases.
7 . The vehicle control device according to claim 4 , wherein the processor is further configured to
increase the acceleration adjustment value as the road gradient increases and reduce the acceleration adjustment value as the road gradient decreases.
8 . A non-transitory computer-readable storage medium storing program instructions that cause a vehicle control device to control a host vehicle to perform a cruise control that causes the host vehicle to maintain travel at a set speed, the cruise control comprising:
acquiring a detection value output from a sensor installed on the vehicle, the sensor being configured to detect surroundings of the vehicle; and
determining whether a traffic factor that affects the cruise control is present based on the acquired detection value while the cruise control is performed, wherein
the program instructions cause vehicle control device to adjust a first acceleration that is set in the cruise control in response to a determination that the traffic factor affects the cruise control, and
the traffic factor includes one or more of a lane width, a road curvature, or a road gradient associated with a road environment in which the vehicle is travelling.
