A vehicle-mounted local network system

Abstract

The invention discloses a vehicle-mounted local network system, comprising a main control unit, a hybrid cable and a plurality of intelligent electric appliance terminals. The hybrid cable comprises apower supply line for power supply and transmission and a signal line for signal transmission. The plurality of intelligent electric appliance terminals are connected to the hybrid cable and are connected with the main control unit through the hybrid cable. The invention can quickly connect the main control unit and several intelligent electric appliance terminals through only one integrated hybrid cable to form a simple, high-performance and low-cost local vehicle-mounted network system.

Description

technical field [0001] The invention relates to the field of automotive electronic systems, in particular to a vehicle-mounted local network system. Background technique [0002] Most of the existing automotive electrical control systems have entered the bus-type automotive electrical control system (currently, most of them are CAN bus control systems), and the bus information is used to correlate electrical logic and control logic, which reduces the wiring and control logic of traditional electrical appliances and improves the efficiency. The reliability of the system and the easy realization of vehicle body information; however, the wiring connection of the bus-type automotive electrical system is still too complicated, and the system cost is still high. Because the bus-type automotive electrical system has high requirements on the reliability of the control unit, the performance of the control module shell, and the performance of the connector, it brings about an increase...

Problems solved by technology

[0002] Most of the existing automotive electrical control systems have entered the bus-type automotive electrical control system (currently, most of them are CAN bus control systems), and the bus information is used to correlate electrical logic and control logic, which reduces the wiring and control logic of traditional electrical appliances and improves the efficiency. Reliability of the system and easy realization of body informatization; however, the wiring connection of the bus-type automotive electrical system is still too complicated, and the system cost is still high

Because the bus-type automotive electrical system has high requirements on the reliability of the control unit, the performance of the control module shell, and the performance of the connector, it brings about an increase in cost. On the other hand, in order to reduce the cost of the control unit, often a control unit is associated with more electrical appliances. The reliability of the control unit is low, and the wiring harness of the connector is complicated

[0003] Although the patented technology with the published patent No. CN 104908682A has moved the control drive unit to the local electrical appliances, the wiring harness and connectors are still in the traditional mode, and the wiring harness is complicated to manufacture and has low reliability.
