Problems solved by technology

However, since the hydraulic braking is performed first to ensure braking safety, that is, since the hydraulic pressure is unconditionally used first at the early braking, the fuel ratio is deteriorated due to the loss of the regenerative braking amount
[0008] Second, there is the problem of drive variation
However, since the response of regenerative braking is slow, an unexpected and uncomfortable feeling can occur in the initial stage of braking, and in the case where the increase gradient of the amount of regenerative braking is adjusted downward to minimize the discomfort, eventually, repeated reduction The vicious cycle of regenerative braking and worsening fuel ratio

Abstract

A method for determining an amount of regenerative braking includes: determining a possible amount of regenerative braking at a time of braking a vehicle; distributing a first amount of regenerative braking up to the possible amount of regenerative braking as the amount of regenerative braking; distributing a second amount of regenerative braking remaining from the possible amount of regenerative braking as an amount of hydraulic braking; and performing, first, regenerative braking by issuing a motor torque instruction according to the possible amount of regenerative braking and, second, friction braking using the amount of hydraulic braking.

Description

technical field [0001] The present disclosure generally relates to methods for determining an amount of regenerative braking. More particularly, it relates to a method for determining an amount of regenerative braking to maximize the amount of regenerative braking by performing early control of regenerative braking at an early stage of braking. Background technique [0002] The driving mode of a hybrid vehicle includes an electric vehicle (EV: Electric Vehicle) mode in which only electric motor power is used, a hybrid electric vehicle (HEV: Hybrid Electric Vehicle) mode in which an engine is used as a main power source and an electric motor is used as an auxiliary power, and Regenerative Braking (RB: Regenerative Braking) mode in which the battery is charged by recovering braking and inertial energy of the vehicle while driving due to braking or the inertia of the vehicle. [0003] Regarding the latter, regenerative braking is the use of an electric motor to generate electr...
