Description

Technical field

[0001] The present disclosure relates to a signal transmission system for a vehicle, in particular a signal integration system and a two-wheeled vehicle. Prior technology

[0002] The instrumentation of electric motorcycles is mostly configured to receive signals from vehicle controllers, such as Universal Asynchronous Receiver / Transmitter (UART) to display information such as current speed, mileage and battery level on the instrument. Therefore, the existing instrument functions are only used to display basic vehicle message functions such as speed, mileage, battery and electric power assist, but the throttle signal, turn signal signal and brake signal must be analog signals and paired with multiple signal lines to be transmitted back to the vehicle controller.

[0003] However, in the past, most of the analog detection lines in the vehicle line configuration needed to be connected to the vehicle controller, but this line configuration conflicted with the routing method when the connection was performed on the actual vehicle platform. For example, the handle throttle is actually located in the front of the vehicle, but the vehicle controller is often located in the center of the vehicle or under the seat cushion, which results in a long line and assembly line requires a large number of connecting lines and connectors, resulting in increased product costs. It follows that there is currently a lack of an optimized line configuration for electric motorcycles in the market, so the relevant operators are seeking its solution. Contents of the invention

Then, they can connect and exchange information with the main control unit 230 using digital communication (i.e., using a single signal line SL) to achieve vehicle control. Thus, compared to conventional electric motorcycles or electric bicycles, the two-wheeled vehicle 100 disclosed herein has a reduced total number of terminals, a shorter bus length, and a lower total impedance, resulting in reduced voltage drop losses in the wiring.

[0027] In summary, the signal integration system and two-wheeled vehicle disclosed herein have the following advantages: First, they can significantly reduce the total length of the vehicle's wiring harness, and reduce the time and difficulty of wiring harness assembly, thus achieving cost optimization. Second, they reduce the total number of terminals, shorten the bus length, and decrease the total impedance of the two-wheeled vehicle, thereby reducing voltage drop losses in the circuit.
