Title: Driving support system
Inventor: NAKAMURA KEI
IPC: B60W40/04
Filed: 2020-02-21
Abstract: To suppress an excess driving support control for avoiding a collision with a crossing target in front of a vehicle.SOLUTION: A driving support control includes at least one of a deceleration control and a steering control for avoiding a collision with a target in front of a vehicle. The driving support control operates when the target exists in a support area. A crossing target is a target crossing a roadway area in front of the vehicle from a first side to a second side. A support area with respect to the crossing target is divided into a plurality of divided support areas. The plurality of divided support areas include a first support area located on the first side when viewed from the vehicle, and a second support area located on the second side when viewed from the vehicle. A driving support system determines in which of the plurality of divided support areas the crossing target exists, and executes the driving support control at a control strength in accordance with a result of the determination. The control strength when the crossing target exists in the second support area is weaker than when the crossing target exists in the first support area.SELECTED DRAWING: Figure 3
