Title: Driving support device
Inventor: YAMAMOTO YUKI
IPC: G08G1/16
Filed: 2019-10-15
Abstract: To prevent or suppress a situation where driving support for avoiding collision is unnecessarily performed when a preceding vehicle to be a determination target is changed.SOLUTION: A determination area H, for example, is set in front of an own vehicle V1. When at least a part of a preceding vehicle VB that travels in front of the own vehicle V1 overlaps the determination area H, warning such as warning display, warning sound generation, or acceleration limitation is issued to a driver of the own vehicle V1, assuming that there is a collision risk (execution of driving support). For example, when the own vehicle V1 moves to an adjacent lane to overtake the preceding vehicle VB that is traveling in front from a state where the preceding vehicle VB is set as a determination target, a preceding vehicle VC that travels in the adjacent lane is set as a new determination target. When the determination target is changed from the preceding vehicle VB to the preceding vehicle VC, the determination area H is temporarily reduced in a front-rear direction (relaxation of a determination criterion) so that there occurs a state where driving support is not easily performed.SELECTED DRAWING: Figure 4
