determining whether to refer to the map information on the basis of a first result of determination indicating whether the first marking and the second marking match and a second result of determination indicating whether there is a separation between two of the second markings;
determining whether or not to execute each of a plurality of predetermined driving support functions based on a driving mode to be executed among the plurality of driving modes, the first result of determination, the second result of determination, whether or not to refer to the map information, and information on a marking that is used as a reference when the driving mode is executed among the first marking and the second marking; and
setting details of driving support which are able to be executed to be different between a first state in which the map information is referred to and a second state in which the map information is not referred to when the first driving mode based on the first marking is executed.
2 . The vehicle control device according to claim 1 , wherein the processor executes the first driving mode based on the first marking in the first state when there is a separation between the two second markings, and the first markings on right and left sides of the vehicle and at least one of the second markings match.
3 . The vehicle control device according to claim 1 , wherein the processor executes the first driving mode based on the first marking in the second state when there is a separation between the two second markings, and the first markings on right and left sides of the vehicle and both of the second markings do not match and when there is a forward traveling vehicle in front of the vehicle.
4 . The vehicle control device according to claim 1 , wherein the processor executes the second driving mode based on the first marking in the second state when there is a separation between the two second markings, and the first markings on right and left sides of the vehicle and both of the second markings do not match and when there is no forward traveling vehicle in front of the vehicle.
5 . The vehicle control device according to claim 1 , wherein the processor limits executable driving support functions when the first driving mode based on the first marking is executed in the second state in comparison with when the first driving mode based on the first marking is executed in the first state.
6 . The vehicle control device according to claim 5 , wherein the processor limits at least one of a lane change function, a before-curved-lane deceleration function, a curved-lane departure preventing function, and a merging support function when the first driving mode based on the first marking is executed in the second state.
7 . The vehicle control device according to claim 1 , wherein the processor executes the second driving mode based on the first marking in the second state when the first marking is not recognized or when one of the first markings on the right and left sides of the vehicle is not recognized and the other does not match the second marking.
8 . The vehicle control device according to claim 1 , wherein the processor determines the driving mode to be a manual driving mode when a state in which the first marking and the second marking do not match is maintained for a predetermined time or more or when a distance by which the vehicle has traveled in a state in which the two markings do not match is equal to or greater than a predetermined distance.
9 . The vehicle control device according to claim 1 , wherein two second markings are a marking defining the traveling lane of the vehicle recognized from the map information and a centerline of the traveling lane.
10 . A vehicle control method that is performed by a computer, the vehicle control method comprising:
recognizing a surrounding situation of a vehicle including a first marking associated with a traveling lane of the vehicle on the basis of an output from a detection device having detected the surrounding situation of the vehicle;
recognizing a second marking associated with a lane near the vehicle from map information on the basis of position information of the vehicle;
performing driving control for controlling one or both of steering and speed of the vehicle on the basis of results of recognition;
determining a driving mode of the vehicle to be one of a plurality of driving modes including a first driving mode and a second driving mode in which a task which is imposed on an occupant of the vehicle is heavier than the task in the first driving mode, some of the plurality of driving modes including at least the first driving mode being controlled through the driving control;
determining whether to refer to the map information on the basis of a first result of determination indicating whether the first marking and the second marking match and a second result of determination indicating whether there is a separation between two of the second markings;
determining whether or not to execute each of a plurality of predetermined driving support functions based on a driving mode to be executed among the plurality of driving modes, the first result of determination, the second result of determination, whether or not to refer to the map information, and information on a marking that is used as a reference when the driving mode is executed among the first marking and the second marking; and
setting details of driving support which are able to be executed through the driving control to be different between a first state in which the map information is referred to and a second state in which the map information is not referred to when the first driving mode based on the first marking is executed.
11 . A non-transitory computer-readable storage medium causing a computer to perform:
recognizing a surrounding situation of a vehicle including a first marking associated with a traveling lane of the vehicle on the basis of an output from a detection device having detected the surrounding situation of the vehicle;
