Abstract
A driving support apparatus derives position prediction data when T=Tn, which is when a predicted time Tn has elapsed from the present time, based on acquired map data, position data and speed data. Direction prediction data indicating a traveling direction of a vehicle 1 at the time T=Tn is derived based on acquired map data and derived position prediction data. A yaw angle which is an angle formed by a traveling direction D0 represented by e direction data and the traveling direction Dn represented by direction prediction data is derived. A target speed Vn of the vehicle is then derived.
Claims8
A driving support apparatus mounted on a vehicle comprising:
- a map data acquisition unit that acquires map data representing a road on which the vehicle can travel;
- a position data acquisition unit that acquires position data representing a position of the vehicle;
- a speed data acquisition unit that acquires speed data representing a speed of the vehicle;
- a direction data acquisition unit that acquires direction data representing a traveling direction of the vehicle;
- a position data prediction unit that derives position prediction data representing a position of the vehicle when a predetermined predicted time has elapsed based on map data, position data and speed data;
- a direction data prediction unit that derives direction prediction data representing another traveling direction of the vehicle when the predicted time has elapsed based on map data and position prediction data;
- and
- a target speed derivation unit that derives a target speed of the vehicle when the predicted time has elapsed based on the traveling direction indicated by direction data and the other traveling direction indicated by direction prediction data.
