Abstract

The invention provides a transmission control method during regenerative braking of a hybrid vehicle, and the method is directed to providing a transmission control method during regenerative braking of a hybrid vehicle that is capable of accurately estimating the regenerative braking execution amount, by constantly controlling the transmission output torque, that is, the regenerative braking execution amount, until the transmission input speed reaches the speed corresponding to the target transmission stage, through the operating element torque and motor torque intervention control for transmission, when transitioning to the target transmission stage from the current transmission stage of the multistage automatic transmission of the hybrid vehicle, and is capable of accurately estimating the regenerative braking execution amount and simultaneously securing the braking linearity during transmission.

Description

Technical field [0001] The present disclosure relates to a transmission control method during regenerative braking of a hybrid vehicle. More specifically, the present disclosure relates to a transmission control method during regenerative braking of a hybrid vehicle, which is suitable for being able to ensure braking linearity during a gear shift. Background technique [0002] As an example, such as figure 1 As shown, the power transmission system for a hybrid vehicle is configured to include an engine 10 and a motor 12, an engine clutch 13, an automatic transmission 14, an HSG 16 (hybrid start generator), an inverter 18, and a high-voltage battery, in which the engine 10 and the motor 12 are arranged in series with each other, the engine clutch 13 is arranged between the engine 10 and the motor 12 to transmit or disconnect the engine power, the automatic transmission 14 shifts gears and outputs the motor or the motor and the engine power to the driving wheels as a connection to ...
