Vehicle electric back door ECU control system and control method

Abstract

The invention discloses a vehicle electric back door ECU control system which comprises a central processing unit, a CAN signal receiving and transmitting unit with a signal receiving and transmittingfunction, and a CAN bus for receiving vehicle information. One end of the CAN signal receiving and transmitting unit is electrically connected with the CAN bus, and the other end of the CAN signal receiving and transmitting unit is electrically connected with the central processing unit. The vehicle electric back door ECU control system further comprises a supporting rod control device, a door lock control device, a self-suction motor control device, a back door switch, a fault detecting unit with a circuit abnormity detecting function, a buzzer alarm and a power supply unit. The power supplyunit is electrically connected with the central processing unit. The current vehicle state information is judged by obtaining the vehicle CAN bus information, the opening, closing and locking of a back door are automatically controlled according to the vehicle state, a vehicle tail door is safe and reliable in opening and closing, the system is more user-friendly and intelligent and convenient touse for a user and has good economic and social benefits, and user experience is improved.

Description

technical field [0001] The invention relates to the field of vehicle automation control, in particular to an automatic control system and control method for a vehicle electric back door. 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 our country, consumers have put forward higher requirements for driving comfort, safety and operation convenience. The opening and closing of the back door of the car is traditionally operated manually by the driver and occupant after unlocking. , is achieved through pneumatic struts, most of the existing domestic cars generally use pneumatic struts, only higher-spec cars use electric back doors, which are realiz...

Problems solved by technology

[0005] In the prior art, the general electric tailgate can only be opened and closed by an additional tailgate switch, and the tailgate can still be opened when the tailgate switch is touched in a non-parking gear or driving, and even some electric tailgates The tailgate has no anti-pinch function, which will bring some safety hazards. Even some vehicles can still open the tailgate when it is in motion, which may cause damage to consumers' personal property.

For example, the Chinese patent "An Automatic Opening and Closing System of the Back Door of a Car", the authorized announcement number: CN205089116 U, discloses an automatic opening and closing system of the back door of a car, but it does not have functions such as pinching prevention and fault detection, and the structure is simple ,Room for improvement
