Embodiment Construction

[0036] Hereinafter, a vehicle control device according to an embodiment of the present invention will be described with reference to the drawings. First, refer to figure 1 and figure 2 Next, the configuration of the vehicle control device will be described. figure 1 is the structural diagram of the vehicle control device, figure 2 It is the control block diagram of the vehicle control device.

[0037] The vehicle control device 100 of the present embodiment is configured to control the vehicle 1 on which the vehicle control device 100 is mounted (see image 3 etc.) provide different driver assistance controls. The driver can select a desired driving assistance mode from a plurality of driving assistance modes.

[0038] like figure 1As shown, a vehicle control device 100 is mounted on a vehicle 1 and includes a vehicle control computing unit (ECU) 10, a plurality of sensors and switches, a plurality of control systems, and a driver operation unit ( not shown). The plu...

Abstract

Provided is a vehicle control device with which it possible to keep an appropriate distance from a preceding vehicle under various road surface conditions, thereby reducing anxiety felt by a driver. The present invention involves a vehicle control device (100) for controlling vehicle travel, wherein the vehicle control device (100) is characterized by comprising: a nearby vehicle detection unit (10b) that detects a nearby vehicle (3) that is traveling nearby an ego-vehicle (1); a road surface condition estimation unit (10d) that estimates the road condition, which impacts the braking distanceresulting from braking the ego-vehicle; a speed distribution setting unit (10e) that sets a speed limit distribution (40), which defines the upper-limit values of the relative speeds permitted in thevicinity of the nearby vehicle detected by the nearby vehicle detection unit; and a control unit (10f) that controls the speed and / or steering of the ego-vehicle so as to satisfy the speed limit distribution set by the speed limit distribution setting unit. The vehicle control device (100) is further characterized in that the speed distribution setting unit reduces the upper-limit values of the permitted relative speeds when the road surface condition estimation unit has estimated that the road surface condition requires a longer braking distance.

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...
