Travel control device, travel control method, and storage medium

A travel control method executed by a computer, the travel control method comprising:

• calculating, in calculating a route along which a vehicle travels, a first route calculated in a case where a destination is set, or a second route calculated in a case where a destination is not set;
• performing travel control of the vehicle along the calculated first route or the calculated second route;
• when the vehicle proceeds to a point at which a plurality of route candidates exist, calculating the second route such that the vehicle proceeds to a first road determined based on a predetermined priority order among the plurality of route candidates;
• and
• in a case where an angle of the first road with respect to a road on which the vehicle travels when the vehicle enters the point is equal to or less than a predetermined angle, or in a case where a steering control amount becomes equal to or greater than a predetermined value in a case where the vehicle proceeds to the first road, calculating the second route such that the vehicle proceeds to a second road having a lower priority order than the first road.

A computer-readable non-transitory storage medium storing a program, the program causing a computer to:

• calculate, in calculating a route along which a vehicle travels, a first route calculated in a case where a destination is set, or a second route calculated in a case where a destination is not set;
• perform travel control of the vehicle along the calculated first route or the calculated second route;
• when the vehicle proceeds to a point at which a plurality of route candidates exist, calculate the second route such that the vehicle proceeds to a first road determined based on a predetermined priority order among the plurality of route candidates;
• and
• in a case where an angle of the first road with respect to a road on which the vehicle travels when the vehicle enters the point is equal to or less than a predetermined angle, or in a case where a steering control amount becomes equal to or greater than a predetermined value in a case where the vehicle proceeds to the first road, calculate the second route such that the vehicle proceeds to a second road having a lower priority order than the first road.
