Vehicle control device and vehicle control method

Abstract

The invention relates to a vehicle control device and a vehicle control method. The vehicle control device that is provided with: a target-information acquisition unit (12) that acquires a current position, which is the relative position of a passerby with respect to an own vehicle; a predicted-collision-position calculation unit (14) that, as a predicted collision position, calculates, on the basis of the current position, the position at which the distance in the advancement direction of the own vehicle between the passerby and the own vehicle will be zero; a crossing determination unit (15)that determines whether the passerby is crossing the path of the own vehicle; a regulation-value setting unit (16) that sets regulation values that indicate a left-right width in a lateral directionthat is orthogonal to the advancement direction of the own vehicle; and a presence determination unit (17) that, on the basis of the predicted collision position and of the regulation values, determines whether the passerby is in the path of the of the own vehicle. When it has been determined that the passerby is crossing the path of the own vehicle, the regulation-value setting unit (16) sets theregulation value for either the left or the right side of the position of the predicted collision position in the advancement direction to be larger than the regulation value for the other side.

Description

technical field [0001] The present disclosure relates to a vehicle control technique for determining whether or not an object exists on a route of a host vehicle, and controlling the vehicle based on the determination result. Background technique [0002] Conventionally, pre-collision safety (PCS: Pre-Crash Safety) has been realized to reduce or prevent collision damage between objects such as other vehicles, pedestrians, and road structures located in front of the own vehicle in the traveling direction, and the own vehicle. In the PCS, the predicted time until the host vehicle collides with the target, that is, the predicted time to collision (TTC: Time to Collision) is calculated based on the relative distance and relative speed or relative acceleration between the host vehicle and the target. Furthermore, in the PCS, based on the calculated collision prediction time, the driver of the own vehicle is notified of the approach through an alarm device or the like, or the brak...

Problems solved by technology

As a result, although the movement of pedestrians is actually a movement with a low risk of collision, if the judgment area is set to a large size, the safety device may operate unnecessarily (operating when it is not necessary).
