Abstract

A vehicle control device incudes a deceleration detection unit that detects a deceleration of a vehicle, a stop schedule specifying unit that specifies that the vehicle is scheduled to stop, a brake control unit that starts reducing a brake pressure when a vehicle speed of the vehicle becomes equal to or less than a threshold value, and a threshold value determination unit that determines the threshold value such that the threshold value increases as the deceleration detected by the deceleration detection unit increases after the stop schedule specifying unit specifies that the vehicle is scheduled to stop.

Claims (11)

1. A vehicle control device comprising:

a processor configured to:

detect a deceleration of an own vehicle which follows a preceding vehicle;

specify that the own vehicle is scheduled to stop based on a change in a speed of the preceding vehicle behind which the own vehicle travels;

start reducing a brake pressure when a traveling speed of the own vehicle becomes equal to or less than a threshold value; and

determine the threshold value such that the threshold value increases as the detected deceleration increases after the specifying that the own vehicle is scheduled to stop.

2. The vehicle control device according to claim 1 , wherein the processor is further configured to:

specify a gradient of a road where the own vehicle is traveling, and

wherein the processor determines the threshold value based further on the specified gradient.

3. The vehicle control device according to claim 1 , wherein the processor is further configured to specify a weight of the own vehicle, and

wherein the processor determines the threshold value based further on the specified weight.
