Vehicle control device for controlling lane change operation, medium for storing computer program for controlling vehicle lane change operation, and method for controlling vehicle lane change operation
A vehicle control device has a processor configured to generate a first traveling lane plan representing the traveling lane in which the vehicle is traveling within a first driving zone of a navigation route, to generate a first lane change plan representing movement of the vehicle between lanes, based on the first traveling lane plan or on surrounding environment information and, when the first lane change plan has been generated, to determine whether or not there exists a control transfer request zone at less than a first reference distance from the location of the vehicle on the post-movement traffic lane, or a lane change schedule zone at less than a second reference distance, and the first lane change plan is cancelled when such a control transfer request zone or lane change schedule zone exists.
1. A vehicle control device comprising:
a processor that is configured to
generate a first traveling lane plan representing a traveling lane in which a vehicle is traveling within a first driving zone of a navigation route, based on a current location of the vehicle, map information and the navigation route,
generate a first lane change plan representing movement of the vehicle between lanes, based on the first traveling lane plan, on surrounding environment information, or a request for movement between lanes by the driver,
determine whether or not there exists a control transfer request zone where the driver is to be given a request to transfer driving of the vehicle from automatic control to manual control at less than a first reference distance from the location of the vehicle on a post-movement traffic lane, when the first lane change plan has been generated, and
control the vehicle to cancel the first lane change plan and refrain from changing lanes when the control transfer request zone exists at less than the first reference distance from the location of the vehicle on a post-movement traffic lane.
2. The vehicle control device according to claim 1 , wherein the processor is further configured to
estimate a location of the vehicle on the post-movement traffic lane,
generate a second traveling lane plan representing the traveling lane in which the vehicle is traveling within a second driving zone of the navigation route, based on the location of the vehicle on the post-movement traffic lane, the map information and the navigation route, and
generate a second lane change plan representing movement of the vehicle between lanes based on the second traveling lane plan.
3. The vehicle control device according to claim 2 , wherein the processor is further configured to set the lane change schedule zone to be an automatic lane change schedule zone in which movement of the vehicle between lanes by automatic control is planned or a manual lane change schedule zone in which movement of the vehicle between lanes by manual control is planned, based on the second traveling lane plan.
4. The vehicle control device according to claim 1 , wherein the processor is further configured to
generate the first lane change plan based on the first traveling lane plan, or the surrounding environment information, and
determine whether or not the control transfer request zone or lane change schedule zone exists, when the first lane change plan has been generated.
5. A computer-readable, non-transitory medium storing a computer program for vehicle control, wherein the computer program causes a processor to execute a process, the process comprising:
generating a first traveling lane plan representing a traveling lane in which a vehicle is traveling within a first driving zone of a navigation route, based on a current location of the vehicle, map information and the navigation route;
generating a first lane change plan representing movement of the vehicle between lanes, based on the first traveling lane plan or on surrounding environment information;
determining whether or not there exists a control transfer request zone where the driver is to be given a request to transfer driving of the vehicle from automatic control to manual control at less than a first reference distance from the location of the vehicle on a post-movement traffic lane, and
controlling the vehicle to cancel the first lane change plan and refrain from changing lanes when the control transfer request zone exists less than the first reference distance from the location of the vehicle on the post-movement traffic lane.
6. A method for controlling a vehicle carried out by a vehicle control device, the method comprising:
generating a first traveling lane plan representing a traveling lane in which a vehicle is traveling within a first driving zone of a navigation route, based on a current location of the vehicle, map information and the navigation route;
generating a first lane change plan representing movement of the vehicle between lanes, based on the first traveling lane plan or on surrounding environment information;
determining whether or not there exists a control transfer request zone where the driver is to be given a request to transfer driving of the vehicle from automatic control to manual control at less than a first reference distance from the location of the vehicle on a post-movement traffic lane, and
controlling vehicle to cancel the first lane change plan and refrain from changing lanes when the control transfer request zone exists less than the first reference distance from the location of the vehicle on the post-movement traffic lane.
