[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0036] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] As described in the background art, in the related art, a large space is occupied when installing the electric limiter and the door controller, and the transmission time of the control signal is long, and the sensitivity of the electric limiter is low. Figure 1 FIG. 1 is a simplified structural diagram of a vehicle door assembly in the related art. Figure 1 As shown, the door assembly in the related art includes a door 20, an electric limiter 100 and a door controller 200, wherein the electric limiter 100 and the door controller 200 are separately arranged, the electric limiter 100 is installed inside the door 20, and the door controller 200 is installed on the side of the door 20 facing the cockpit. Since the electric limiter 100 and the door controller 200 are separately arranged, it is necessary to reserve installation space on the door 20 respectively, so that the space occupied during installation is large. The electric limiter 100 and the door controller 200 also need to communicate through a wiring harness connection, which increases the cost and increases the weight of the entire vehicle.

[0038] In addition, in the related art, the door controller 200 and the body controller are connected to each other by LIN (Local Interconnect Network) communication, and the communication speed is slow, so that the transmission time of the control signal is long and the sensitivity of the electric limiter 100 is low.

[0039] In view of this, the embodiments of the present application aim to provide an electric limiter assembly, a door assembly and a car. The electric limiter and the door controller are integrated and communicatively connected, and the door controller is communicatively connected to the body controller via a CAN bus, thereby reducing the space used for the installation of the electric limiter and the door controller, and can shorten the signal transmission time, which is beneficial to improving the sensitivity of the electric limiter.

[0040] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail.
