Vehicle control device

Abstract

Provided is a vehicle control device which makes it possible to carry out rapid deceleration and steering depending on the behavior of nearby vehicles, thereby reducing anxiety felt by a driver. The vehicle control device (100) for controlling vehicle travel is characterized by comprising: a nearby vehicle detection unit (10b) that detects nearby vehicles (3) traveling near an ego-vehicle (1); a route information acquisition unit (26) that acquires, from nearby vehicles detected by the nearby vehicle detection unit, travel route information pertaining to a subsequent travel route; a speed distribution setting unit (10d) that sets a speed limit distribution (40), which defines the upper-limit values of relative speeds permitted in the vicinity of the nearby vehicles detected by the nearby vehicle detection unit; and a control unit (10e) that controls the speed and / or steering of the ego-vehicle so as to satisfy the speed limit distribution set by the speed distribution setting unit. Thevehicle control device (100) is further characterized in that the speed distribution setting unit sets the speed limit distribution according to the travel route information acquired by the route information acquisition unit.

Description

technical field [0001] The present invention relates to a vehicle control device, in particular to a vehicle control device for controlling the running of a vehicle. Background technique [0002] Japanese Patent Application Laid-Open No. 2006-218935 (Patent Document 1) describes a driving assistance device for a vehicle. In this driving assistance device for a vehicle, an object located in the traveling direction of the host vehicle is detected, and it is predicted whether a safety distance is ensured when the object is closest to the host vehicle, and driving assistance control is executed when it is predicted that the safety distance cannot be ensured. . In addition, in this driving assistance device for a vehicle, the direction of an object is detected, and a safety distance is set based on the direction. [0003] However, the control of the driving assistance device for a vehicle described in Patent Document 1 is only for the purpose of avoiding a collision, and when t...

Problems solved by technology

[0009] However, even in the control of the speed limit distribution in which a plurality of allowable upper limits of relative speeds are set around the object, when the vehicle in front of the object changes lanes and enters the lane of the own vehicle, etc. Sometimes it is difficult to maintain a sufficient distance between the own vehicle and the preceding vehicle that has changed lanes

Therefore, depending on the behavior of the preceding vehicle, the driver may feel uneasy by relatively rapid deceleration or steering to maintain a sufficient distance, or the ride quality of the vehicle may deteriorate.
