METHOD FOR DETERMINING AMOUNT OF REGENERATIVE BRAKING

摘要

The present invention relates to a cooperative control method for the regenerative braking of an eco-friendly vehicle to maximize the amount of the regenerative braking, by performing the early entrance control of regenerative braking at the beginning of braking. That is, the present invention provides the cooperative control method for the regenerative braking of an eco-friendly vehicle. The possible amount of regenerative braking reliable to a hydraulic braking system is outputted to firstly perform regenerative braking due to the early entrance control of regenerative braking at the beginning of braking. Thereby, the priority control of existing hydraulic braking can be changed into the priority control of regenerative braking. The amount of the regenerative braking can maximized while braking stability due to hydraulic braking is secured. The cooperative control method includes a step of calculating the possible amount of regenerative braking and a step of performing friction braking with the amount of hydraulic braking.
