Abstract
An in-vehicle electronic control unit includes: a positioning calculation unit that acquires GNSS information and acquires positioning information of an own vehicle; a vehicle movement detection unit that detects movement of the own vehicle; and an own vehicle movement determination unit that estimates movement while a vehicle system is stopped, in which the own vehicle movement determination unit determines whether the own vehicle has moved while the vehicle system is stopped, and based on a determination result as to whether the own vehicle has moved, determines whether the positioning calculation unit estimates a current position of the own vehicle by using a position of the own vehicle when the vehicle system is stopped.
Claims8
An in-vehicle electronic control unit comprising:
- a positioning calculation unit that acquires GNSS information and acquires positioning information of an own vehicle;
- a vehicle movement detection unit that detects movement of the own vehicle;
- and
- an own vehicle movement determination unit that estimates movement while a vehicle system is stopped,
- wherein the own vehicle movement determination unit
- determines whether the own vehicle has moved while the vehicle system is stopped, and
- based on a determination result as to whether the own vehicle has moved, determines whether the positioning calculation unit estimates a current position of the own vehicle by using a position of the own vehicle when the vehicle system is stopped.
A position estimation method executed by an in-vehicle electronic control unit, wherein
- the in-vehicle electronic control unit includes
- a positioning calculation unit that acquires GNSS information and acquires positioning information of an own vehicle,
- a vehicle movement detection unit that detects movement of the own vehicle, and
- an own vehicle movement determination unit that estimates movement while a vehicle system is stopped, and
- in the position estimation method,
- the own vehicle movement determination unit determines whether the own vehicle has moved while the vehicle system is stopped,
- based on a determination result as to whether the own vehicle has moved, the own vehicle movement determination unit determines whether the positioning calculation unit estimates a current position of the own vehicle by using a position of the own vehicle when the vehicle system is stopped, and
- the positioning calculation unit estimates a current position of the own vehicle by using a position of the own vehicle when the vehicle system is stopped in accordance with determination by the own vehicle movement determination unit.
