Regenerative braking control device vehicle having the regenerative braking control device and method for controlling the vehicle

摘要

The present invention provides a regenerative braking control device, a vehicle having the same, and a control method for the same. According to an aspect of the present invention, the regenerative braking control device obtains a deceleration value and a deceleration time based on a relative speed and a distance with other vehicles and controls regenerative braking based on the obtained deceleration value and the deceleration time. According to the present invention, the vehicle includes: a motor driving a wheel; a battery supplying driving power to the motor and charged by the motor in the regenerative braking; an obstacle detecting unit detecting an obstacle; a speed detecting unit detecting a driving speed; a front monitoring device obtaining distance from the obstacle based on information detected by the obstacle detecting unit and outputting information on the front of the vehicle based on the obtained distance; and the regenerative braking control device. The regenerative braking control device stores a regenerative braking rate by the each deceleration value corresponding to each of the multiple deceleration times in a lookup table and obtains a driving speed based on the information detected by the speed detecting unit. The regenerative braking control device also obtains the relative speed to the other vehicle based on the obtained distance and the obtained driving speed and obtains the deceleration value and the deceleration time based on the obtained distance, the relative speed, and the predetermined distance. Also, the regenerative braking control device obtains the regenerative braking rate corresponding to the deceleration value and the deceleration time obtained based on the lookup table of a storage unit and outputs a control command corresponding to the regenerative braking rate by the motor.
