Embodiment Construction

[0041] Embodiments of the present invention will be described with reference to the drawings.

[0042] 1. Driving assistance systems

[0043] 1-1. Outline

[0044] figure 1 It is a conceptual diagram for explaining the outline of the driving assistance system 10 of the present embodiment. The driving assistance system 10 executes “driving assistance control” that assists the driving of the vehicle 1 . Driving assistance controls can also be included in automated driving controls. Typically, the driving assistance system 10 is mounted on the vehicle 1 . Alternatively, at least a part of the driving assistance system 10 may be an external device arranged outside the vehicle 1, and the driving assistance control may be performed remotely. That is, the driving assistance system 10 can be distributed in the vehicle 1 and external devices.

[0045] The driving assistance control includes “risk avoidance control” that avoids a risk ahead of the vehicle 1 in advance. More speci...

Abstract

The invention relates to a driving assistance system. Risk potential fields for risk avoidance control (deceleration control) include obstacle potential fields. The obstacle potential field is a risk potential field in which the risk value is maximum at the location of the target and becomes smaller as the distance from the target. The search range is a range between the position of the target and a position separated from the target by a predetermined gap. A minimum point (valley) of the risk potential field is searched in the search range. Deceleration control is performed on the basis of the positional relationship between the minimum point and the target. When there are a plurality of minimum points in the search range, the minimum point closest to the target is selected.

Description

technical field [0001] The present invention relates to a driving assistance control for assisting driving of a vehicle. In particular, the present invention relates to a risk avoidance control for reducing the risk of collision with an object in front of the vehicle. Background technique [0002] Japanese Patent Laid-Open No. 2018-203034 discloses a travel route determination device that determines a travel route of a vehicle. The travel route decision means decides the travel route of the vehicle using the risk potential area and the benefit potential area. Risk potential areas show areas where obstacles such as pedestrians and other vehicles are likely to exist. The interest potential area shows the ideal travel area in which the vehicle should travel. This profit potential area is set based on the driving data of the skilled driver. [0003] Consider "risk avoidance control" for reducing the risk of collision with an object ahead of the vehicle. In particular, consi...
