Abstract
A course prediction method uses a position acquisition circuit configured to acquire a position of a surrounding vehicle and a course prediction circuit configured to predict a course of a host vehicle based on a traveling path of the surrounding vehicle obtained from a history of the position of the surrounding vehicle. In the course prediction method, the course of the host vehicle is predicted by increasing or reducing the size of the traveling path of the surrounding vehicle, based on a turning direction and a lateral position of the surrounding vehicle.
Claims8
A course prediction method setting a traveling path of a host vehicle based on a traveling path of a surrounding vehicle obtained from a history of the position of the surrounding vehicle by using a position acquisition circuit configured to acquire the position of the surrounding vehicle, the method comprising:
- acquiring a traveling route of the host vehicle on at least a map;
- and
- setting the traveling path of the host vehicle by increasing or reducing a size of the traveling path of the surrounding vehicle similar to the traveling route, based on a turning direction and a lateral position of the surrounding vehicle.
A course prediction method setting a traveling path of a host vehicle based on a traveling path of a surrounding vehicle obtained from a history of the position of the surrounding vehicle by using a position acquisition circuit configured to acquire the position of the surrounding vehicle, the method comprising:
- setting the traveling path of the host vehicle by increasing or reducing a size of the traveling path of the surrounding vehicle, based on a turning direction and a lateral position of the surrounding vehicle;
- acquiring map information including at least branching information of a road;
- and
- aborting the set of the traveling path of the host vehicle when determining that the host vehicle is to pass a branching point.
A course prediction device comprising:
- a position acquisition circuit configured to acquire a position of a surrounding vehicle;
- a course prediction circuit configured to set a traveling path of a host vehicle based on a traveling path of the surrounding vehicle obtained from a history of the position of the surrounding vehicle;
- and
