Problems solved by technology

Therefore, when the brake operation is prepared during the regenerative braking when the pedal is released, the regenerative braking force suddenly disappears and the deceleration decreases sharply, which may give the driver a sense of discomfort.

Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described in detail using the drawings. figure 1 It is a schematic system configuration diagram of the vehicle control device according to the present embodiment.

[0042] A vehicle on which the vehicle control device according to the present embodiment can be mounted is a hybrid vehicle. This vehicle includes an engine 10, a first motor generator 11 (referred to as the first MG 11), a second motor generator 12 (referred to as the second MG 12), an inverter 13, a battery 14, a power distribution mechanism 15, a driving force transmission The mechanism 16 and the hybrid ECU 50 serve as a travel drive device. Among them, ECU is the abbreviation of Electric Control Unit.

[0043] The engine 10 is a petrol engine, but could also be a diesel engine.

[0044] The power split mechanism 15 splits the driving force of the engine 10 into power for driving its own output shaft 15 a and power for driving the first MG 11 a...

Abstract

The invention relates to a control device for a vehicle and aims to prevent a driver from feeling uncomfortable as much as possible when automatic braking to prepare for collision avoidance is started. A hybrid ECU 50 reads mode information during regenerative braking (S42), and when friction braking force control in a preparation mode is started (Yes in S44), gradually reduces regeneration braking force (S45). This can prevent a rapid change of deceleration of a vehicle. When the friction brake force control in a collision avoidance braking mode is started during the regenerative braking (Yes in S43), the hybrid ECU 50 eliminates the regenerative braking force promptly (S46). This can decelerate the vehicle at deceleration for collision avoidance.

Description

technical field [0001] The present invention relates to a control device for a vehicle that assists a driver in avoiding a collision between the own vehicle and an obstacle. Background technique [0002] Conventionally, a vehicle equipped with a collision avoidance assist device is known. The collision avoidance assist device automatically brakes to decelerate the vehicle when a sensor such as a radar detects an obstacle with a high possibility of the own vehicle colliding with it. For example, in the collision mitigation device proposed in Patent Document 1, the collision prediction time until the vehicle collides with an obstacle is calculated, and if the collision prediction time is less than the assist time, the automatic braking 1 is activated, and if the collision prediction time is less than the assist time A short relief time makes automatic braking 2 work. The automatic braking 1 is used to assist a warning and the driver's collision avoidance operation, and the a...
