Title:
電動車両の回生制御装置
Document Type and Number:
Japanese Patent JP5293273
Kind Code:
B2
Abstract:

To provide a regeneration control device for an electric vehicle that increases a regeneration amount during foot braking.

The regeneration control device for the electric vehicle includes: a motor/generator MG for driving wheels by power from a battery 4; an inverter 3 for regenerating power, generated by the motor/generator MG due to deceleration rotation of the wheels, to the battery 4; a brake stroke sensor 20 for detecting operation of a foot brake; and an accelerator opening sensor 16. The regeneration control device also includes: a regeneration-amount measuring means for measuring a regeneration amount, regenerated to the battery 4, for each use of the foot brake in a period during which the foot brake is in use while detecting the operation of the foot brake by the brake stroke sensor 20 during traveling; a storage means for storing the regeneration amount measured by the regeneration-amount measuring means; and a determining means that determines whether the regeneration efficiency is poor or not on the basis of the regeneration amount of the foot brake in the storage means. When the determining means determines that the regeneration efficiency is poor, a regenerative gain of a regenerating means is increased so as to increase the regeneration amount.
