Vehicle controller, and method and computer program for controlling vehicle
A vehicle controller includes a processor configured to detect the type of lane line demarcating a travel lane being traveled by a vehicle from a sensor signal generated by a sensor mounted on the vehicle, the sensor signal representing surroundings of the vehicle, and determine whether the detected type of lane line matches the type of lane line represented in map information between the travel lane and an adjacent lane adjacent thereto at the current position of the vehicle when a lane change to the adjacent lane is required. The processor is further configured to control the vehicle to start a lane change to the adjacent lane in the case that the detected type of lane line matches the type of lane line represented in the map information.
1. A vehicle controller comprising:
a memory configured to store map information representing individual lanes on a road and the types of lane lines between lanes; and
a processor configured to:
detect the type of lane line demarcating a travel lane being traveled by a vehicle from a sensor signal generated by a sensor mounted on the vehicle, the sensor signal representing surroundings of the vehicle, and
determine whether the detected type of lane line at a current position of the vehicle matches the type of lane line represented in the map information between the travel lane and an adjacent lane adjacent thereto at the current position of the vehicle when a lane change to the adjacent lane is required, the processor controlling the vehicle so that the vehicle continues traveling on the travel lane when a lane change is required, in the case that the detected type of lane line differs from the type of lane line represented in the map information, and to start a lane change to the adjacent lane only in the case that the detected type of lane line matches the type of lane line represented in the map information.
2. A method for controlling a vehicle, comprising:
detecting the type of lane line demarcating a travel lane being traveled by a vehicle from a sensor signal generated by a sensor mounted on the vehicle, the sensor signal representing surroundings of the vehicle;
determining whether the detected type of lane line at a current position of the vehicle matches the type of lane line represented in map information between the travel lane and an adjacent lane adjacent thereto at the current position of the vehicle when a lane change to the adjacent lane is required, the map information representing individual lanes on a road and the types of lane lines between lanes; and
controlling the vehicle so that the vehicle continues traveling on the travel lane when a lane change is required, in the case that the detected type of lane line differs from the type of lane line represented in the map information, and to start a lane change to the adjacent lane only in the case that the detected type of lane line matches the type of lane line represented in the map information.
3. A non-transitory recording medium that stores a computer program for controlling a vehicle, the computer program causing a processor to execute a process comprising:
detecting the type of lane line demarcating a travel lane being traveled by a vehicle from a sensor signal generated by a sensor mounted on the vehicle, the sensor signal representing surroundings of the vehicle;
determining whether the detected type of lane line at a current position of the vehicle matches the type of lane line represented in map information between the travel lane and an adjacent lane adjacent thereto at the current position of the vehicle when a lane change to the adjacent lane is required, the map information representing individual lanes on a road and the types of lane lines between lanes; and
controlling the vehicle so that the vehicle continues traveling on the travel lane, in the case that the detected type of lane line differs from the type of lane line represented in the map information when a lane change is required, and to start a lane change to the adjacent lane only in the case that the detected type of lane line matches the type of lane line represented in the map information.
