Regeneration control device for vehicle

Abstract

A regeneration control device (1) for a vehicle includes: a motor control unit (4) that drives a motor generator (3) connected to running wheels (2) of the vehicle at the time of decreasing a vehicle speed, so as to generate electricity, performing regenerative braking; a paddle switch (12) that performs increasing / decreasing operation on a regeneration amount Tr by the motor generator (3); and a main control unit (20) that performs increasing / decreasing control on the regeneration amount Tr continuously in response to the increasing / decreasing operation by the paddle switch (12), wherein the main control unit (20) sets a regeneration amount increasing rate Ru in an increasing operation of the regeneration amount Tr by operation of an UP switch of the paddle switch (12) to be higher than a regeneration amount decreasing rate Rd in a decreasing operation of the regeneration amount Tr by operation of a DOWN switch (14).

Description

technical field [0001] The present invention relates to a regeneration control device for a vehicle capable of performing an adjustment operation of a regeneration amount. Background technique [0002] According to conventional practice, regenerative braking is incorporated in vehicles having a motor for driving, for example in electric vehicles and hybrid vehicles. During deceleration, downhill driving or other situations of the vehicle, the regenerative braking device uses the motor as a generator, converting kinetic energy into electrical energy to charge the battery in the vehicle. [0003] Some types of regenerative braking devices control the amount of regeneration (regeneration load) by the motor. For example, the regeneration amount is controlled based on the depression amount of the brake pedal. [0004] Japanese Patent Laid-Open No. 2005-168283 discloses a vehicle including an operation device that allows a driver to set a regeneration amount. The operating devi...

AI Technical Summary

Problems solved by technology

[0005] However, in order for the above-mentioned vehicle to be able to switch the amount of regeneration step by step, it is difficult for the vehicle to decelerate smoothly

In addition, when it is desired to change the regeneration amount in a large amount at once, the operation means for switching the regeneration amount needs to be operated many times, which is difficult

[0006] In addition, with the vehicle disclosed in Patent Document 1 that allows continuous adjustment and setting of the regeneration amount, it is also difficult to achieve a balance between immediately changing the regeneration amount in large quantities and finely setting the regeneration amount
