The control system comprises a vehicle power supply, a power supply management module, a control unit MCU (Microprogrammed Control Unit), a standby power supply and a door handle heating relay, and the output end of the standby power supply is connected to the power supply management module; the output end of the MCU is connected to a door handle heating relay, the heating relay is connected in series in a power supply loop of a heating module, and the heating module is used for heating the hidden door handle. According to the hidden door handle, the defect that the hidden door handle cannot be popped up due to power failure of the power supply is reduced by adding the standby power supply, meanwhile, the defect that the door handle with a hidden door handle code cannot be popped up is overcome as much as possible by adding an electric heating mode and / or a linkage vehicle window mode, and the use experience of the hidden door handle is improved.

A gate drive circuit adapted to high junction temperature environments, and its turn-on and turn-off methods, are disclosed. The gate drive circuit includes a main three-terminal transistor, a turn-off circuit, and an auxiliary circuit. The added auxiliary circuit generates an auxiliary current signal, either in the same direction or opposite to the control signal current, to the control electrode of the main three-terminal transistor during the turn-on and turn-off processes within a preset time period. This disclosure enables the generation of corresponding positive or negative auxiliary current signals at the control electrode of the three-terminal transistor. During the conduction process, the auxiliary circuit can generate a reverse auxiliary current signal at the control electrode of the three-terminal transistor during the current rise phase, reducing the drive current of the turn-on signal to decrease di. d / dt, suppressing the turn-on current; during the turn-off process, the auxiliary circuit can generate a unidirectional auxiliary current signal at the control electrode of the three-terminal transistor in the current-decreasing segment, increasing the drive current of the turn-off signal and accelerating the turn-off speed.
