    Abstract: A hybrid electric vehicle and a braking control method thereof are provided. The method includes determining, by a first controller, a total braking amount corresponding to a brake pedal manipulation amount and transmitting a regenerative braking request corresponding to at least a portion of the total braking amount to a second controller. A state of a regenerative braking system having a motor and a battery is determined and a regenerative braking execution amount is calculated by selectively using a first torque corresponding to a torque command transmitted to a third controller to operate the motor based on the regenerative braking request or a second torque measured by the third controller based on the determined state. A braking force of a frictional brake is determined based on the calculated regenerative braking execution amount and the total braking amount.

A high voltage DC bus electrically connects the traction battery to the electric machine. A controller monitors and commands power flow through the DC bus, the electric machine, and the battery. In response to a key-off event, the controller immediately discharges the DC bus by providing a current to the electric machines. This discharge continues until the voltage on the DC bus reaches a threshold. As the speed of the electric machine decreases towards a speed threshold, the voltage in the DC bus is maintained. Once the electric machine speed reduces past the threshold, the DC bus discharges the remaining voltage in the DC bus at a rate slower than the first immediate discharge.
