Problems solved by technology

At the same time, due to the large working current of some electrical appliances such as electric window regulators, the requirements for the electrical and mechanical properties of the control switch are getting higher and higher, and the corresponding costs are also higher.
It can be seen that the current multi-wire control method is not economical, and because of the existence of a large number of wiring harness contacts, the reliability and safety of the door electrical appliances are lower, and at the same time, the complexity of the wiring harness brings a lot of inconvenience to the improvement and production of models.

Abstract

The invention is an one-way transmission control system for a kind of car door electric unit; the system includes an electric master unit and several electric controlled units. The electric master unit is set in one car door, there sets an electric controlled unit in each car door, the electric master unit is connected to each electric controlled unit through a control wire. The electric master unit includes a master microchip, a status control microchip, an inputting circuit, a power circuit, status instructing circuit, communication circuit, high frequency receiving circuit, electric erasable storing circuit, driving circuit, outputting circuit and protection circuit. The electric controlled unit includes a microchip, inputting circuit, power circuit, and status instructing circuit, communication circuit and driving circuit and outputting and protection circuit. The invention uses a control wire to realize that it control the electric controlled unit on other car door through the master unit, thus the invention can upgrade the safety and reliability of electric device.

Description

technical field [0001] The invention relates to an automobile electric appliance control device, in particular to a single-line transmission control system for an automobile door electric unit which performs single-line control on a plurality of electric units of the car door. Background technique [0002] Most of the existing car doors are equipped with electrical appliances such as central locks, electric window regulators, electric rear windows, and door indicator lights, and the electrical appliances of each door can be controlled by the driver from the left front door or from the corresponding control of each door. A switch controls its action. In order to effectively control the normal operation of the door electrical appliances, generally each electrical unit must be connected with the control wires from the driver's door to each door electrical appliance one by one. For example, the two control wires of the electric door lock of each door must be connected in paralle...
