Abstract
A driving assistance apparatus includes a position detection part, a road shape recognition part, a steering element, a driving assistance control part that controls the steering element based on the position information and the shape of the road, and an information display control part. The driving assistance control part identifies a target point where lane change needs to be completed based on the shape of the road and further determines a first point and a second point between the target point and the host vehicle. The information display control part displays information on a distance or time from a position of the host vehicle to the first point and information on a distance or time from the position of the host vehicle to the second point.
Claims8
A driving assistance apparatus comprising:
- a position detection part configured to detect position information of a host vehicle;
- a road shape recognition part configured to recognize a shape of a road on which the host vehicle is scheduled to travel;
- a steering element configured to change a traveling direction of the host vehicle;
- a driving assistance control part configured to control the steering element such that the host vehicle changes multiple lanes based on the position information detected by the position detection part and the shape of the road recognized by the road shape recognition part, resulting in multiple lane changes;
- and
- an information display control part configured to visually present information to a driver driving the host vehicle, wherein the driving assistance control part:
- identifies a target point where the multiple lane changes are to be completed, based on the shape of the road recognized by the road shape recognition part,
- determines a number of first point points based on a number of lane changes of the multiple lane changes, wherein the respective first points comprise respective points between the target point and the host vehicle, and
- determines a second point between the target point and the host vehicle, wherein the second point is:
- closer to the target point than a selected first point of the respective points between the target point and the host vehicle, or
- the same point as the target point,
- wherein the information display control part displays;
- information on at least one of a distance or a time from a position of the host vehicle to the selected first point, and
- information on at least one of a distance or a time from the position of the host vehicle to the second point, wherein the selected first point represents a first critical point where the lane change by the driving assistance control part is performed, and wherein the second point represents a second critical point where the lane change by the driver is performed.

A driving assistance method comprising:
- a position detection process of detecting position information of a host vehicle;
- a road shape recognition process of recognizing a shape of a road on which the host vehicle is scheduled to travel;
- a driving assistance control process of controlling a steering element that changes a traveling direction of the host vehicle such that the host vehicle changes multiple lanes based on the position information detected through the position detection process and the shape of the road recognized through the road shape recognition process, resulting in multiple lane changes;
- and
- an information display control process of visually presenting information to a driver driving the host vehicle, wherein the driving assistance control process:
- identifies a target point where lane change needs to be completed based on the shape of the road recognized through the road shape recognition process,
- determines a number of first points based on a number of lane changes of the multiple lane changes, wherein the respective first points comprise respective points between the target point and the host vehicle, and
- determines a second point between the target point and the host vehicle, wherein the second point is:
- closer to the target point than a selected first point of the respective points between the target point and the host vehicle, or
- the same point as the target point,
- wherein the information display control process displays:
- information on at least one of a distance or a time from a position of the host vehicle to the selected first point, and
- information on at least one of a distance or a time from the position of the host vehicle to the second point, wherein the selected first point represents a first critical point where the lane change by the driving assistance process is performed, and wherein the second point represents a second critical point where the lane change by the driver is performed.
