Abstract

In a drive assist system, a map data acquiring section acquires a forward road shape and a rearward road shape. The forward road shape represents a road shape at a forward position in front of a current position of an own vehicle on a road on which the own vehicle drives. The rearward road shape represents a road shape at a rearward position on the road. The rearward position is behind the forward position and in front of the current position of the own vehicle on the road. An assist control calculation section determines steering characteristics of the own vehicle at the target position located between the forward position and the rearward position based on the forward road shape and the rearward road shape, and adjusts a steering angle of the own vehicle on the basis of the determined steering characteristics of the own vehicle.

Claims14

Dependent claims

A steering control device executing steering control of an own vehicle, comprising a computer system including a central processing unit, the computer system being configured to provide:

a road shape information acquiring section which acquires a forward road shape which represents a road shape at a forward position in front of a current position of an own vehicle on a road, on which the own vehicle drives, and acquires a rearward road shape which represents a road shape at a rearward position on the road, the rearward position being behind the forward position and being in front of the current position of the own vehicle on the road;
a characteristics determination section which determines steering characteristics of the own vehicle at a target position on the road on the basis of the forward road shape and the rearward road shape acquired by the road shape information acquiring section, the target position being located between the forward position and the rearward position on the road;
and
a steering angle control section which adjusts the steering angle of the own vehicle on the basis of the steering characteristics of the own vehicle determined by the characteristics determination section.
