Car stern door ECU controller and control method

Abstract

The invention discloses a car stern door ECU controller and a control method. The car stern door ECU controller includes an outer shell and an ECU, an control system of the ECU includes a central processing unit, a CAN signal receiving and transmitting unit and a CAN bus which is used for receiving car information, one end of the CAN signal receiving and transmitting unit is electrically connectedwith the CAN bus, and the other end of the CAN signal receiving and transmitting unit is electrically connected with the central processing unit; the car stern door ECU controller further includes astay rod control device, a door lock control device, a self-absorption motor control device, a stern door switch, a fault detect unit, a buzzer alarm and a power supply unit. According to the car stern door ECU controller and the control method, car condition information at present is judged by the acquired car CAN bus information, the opening and closing and the locking of the stern door can be automatically controlled according to the car condition to enable the opening and closing of the stern door to be safe and reliable, the outer shell bearing the weight of the ECU adopts a structural style of an assembly of an upper shell body and a lower shell body which are produced in a separate moldmaking, the requirements for manufacturing difficulty and assembly accuracy are lowered; and the upper and the lower shell bodies are produced in a separate moldmaking, the strength is high, the forming is easy, and the yield rate is high.

Description

technical field [0001] The invention relates to the technical field of vehicle ECUs, in particular to a vehicle tailgate ECU controller and a control method. Background technique [0002] ECU (Electronic Control Unit) electronic control unit, also known as "driving computer", "vehicle computer" and so on. It is widely used in the automotive field. The ECU includes a casing and internal components, and its internal components are mainly composed of circuit boards and coils. [0003] With the continuous popularization of domestic cars in my country, consumers have put forward higher requirements for driving comfort, safety and operation convenience. The opening and closing of the tailgate of a car is traditionally operated manually by the driver and passenger after unlocking It is realized through pneumatic struts. Most of the existing domestic cars generally use pneumatic struts. Only higher-spec cars use electric tailgates, which are realized through electric struts. Howeve...

Problems solved by technology

[0007] The traditional ECU shell is divided into an upper cover and a lower cover. To a certain extent, it solves the sealing problem of the ECU shell, but there are some defects, such as poor waterproof performance and uniform heat dissipation, and unsatisfactory strength of the shell, etc.
