[0053] The connection between the socket interface definition 7 and the CAN circuit 62 is achieved through the CANH (CAN High) and CANL (CAN Low) pins. This is a typical CAN (Controller Area Network) bus connection method for realizing communication between various electronic control units (ECUs) inside the vehicle.

[0054] The following is a detailed description of this connection method:

[0055] 1. CANH pin:

[0056] This is the high-level signal line of the CAN bus. In CAN bus communication, the CANH and CANL pins together form a differential signal pair for data transmission. CANH usually carries the level signal of logic "1".

[0058] This is the low-level signal line of the CAN bus. Corresponding to the CANH pin, CANL usually carries the level signal of logic "0".

[0059] 3. CAN bus communication principle:

[0060] The CAN bus uses differential signal transmission, which means that data is represented by the voltage difference between CANH and CANL. This differential signal transmission method helps reduce electromagnetic interference (EMI) and improve the reliability of communication.

[0061] In the CAN bus, logic "1" is usually represented by a low voltage difference between CANH and CANL (for example, CANH is 2.5V and CANL is 1.5V), while logic "0" is represented by a high voltage difference (for example, CANH is 1.5V and CANL is 2.5V).

[0062] The socket interface definition 7 may include multiple pins, where CANH and CANL are specific pins for connecting to the CAN circuit 62. This interface design allows the CAN circuit 62 to communicate with other CAN devices (such as sensors, controllers, etc.) via the CAN bus. Through the socket interface definition 7, the CAN circuit 62 can be conveniently connected to the vehicle's CAN network to achieve data exchange with other ECUs. In motorcycles or cars, the CAN bus is widely used in various electronic systems, such as engine management systems, body electronic systems, safety systems, etc. Through the CAN bus, these systems can share data in real time to improve the performance and safety of the vehicle. The connection of the socket interface definition 7 to the CAN circuit 62 via the CANH and CANL pins is a key part of realizing the CAN network communication inside the vehicle.
