The plurality of half-bridge drive assemblies are configured to drive a plurality of drive devices to pivot the first and second doors between a closed position and an open position, and to drive a plurality of electric suction locks to lock or unlock the first and / or second doors. When both the first and second doors are in the closed position, there is an overlapping portion between the first and second doors. In this manner, the domain controller can be adapted for use with a vehicle's detachable rear tailgate system.

[0030] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of a vehicle provided in some embodiments of the present application. The vehicle 1000 provided in the present application may include, but is not limited to, a detachable tailgate system 100.

[0032] Specifically, the first drive device 121 and the second drive device 122 are both electrically connected to the domain controller 110. The first door 140 is drivably connected to the first and second drive devices 121, 122, to automatically open and close when actuated. When the first and second drive devices 121, 122 actuate the first door 140, the first door 140 can pivot between a closed position and an open position. The first electric suction lock 131 is electrically connected to the domain controller 110 and is used to lock and unlock the first door 140.

The third drive device 123 is electrically connected to the domain controller 110. The second door 150 is drivably connected to the third drive device 123, to automatically open and close when actuated. When the third drive device 123 drives the second door 150, the second door 150 can pivot between a closed position and an open position.

When both the first door 140 and the second door 150 are in the closed position, there is an overlap between the first door 140 and the second door 150. This requires the domain controller 110 to control the movement of the first door 140 and the second door 150 in a certain logical sequence to prevent collision between the first door 140 and the second door 150. In this embodiment, the first door 140 is an overhead door hinged to the vehicle body at an upper position, and the second door 150 is a floor door hinged to the vehicle body at a lower position.

Among them, when the first door 140 and the second door 150 are both in the closed position, there is an overlapping part between the first door 140 and the second door 150, so that the control circuit 111 needs to control the movement of the first door 140 and the second door 150 in a certain logical order to avoid collision between the first door 140 and the second door 150.

[0034] Optionally, the drive circuit 112 is a multi-channel half-bridge gate drive chip, which is used to amplify the control signal from the control circuit 111 to quickly and effectively switch the on and off states of several half-bridge drive components 113, thereby controlling the direction and magnitude of the current to drive several drive devices 120 and several electric suction locks 130.
