Title:
ECU CONTROL MOTHERBOARD FOR AUTOMOTIVE POWER TAILGATE
Document Type and Number:
WIPO Patent Application WO/2019/127601
Kind Code:
A1
Abstract:
An ECU control motherboard for an automotive power tailgate, comprising a motherboard (1), a microprocessor (1-1) provided on the motherboard (1), an EEPROM circuit module (1-2), a high-speed CAN transceiver (1-3), a first bridge type motor driving module (1-4) for driving an electric strut motor (2), a power supply module (1-5), a power source reverse-connection protection circuit module (1-6), a high-end voltage driving module (1-7) for driving a tailgate unlocking motor (3), a second bridge type motor drive module (1-8) for driving a tailgate self-priming motor (4), a debugging download interface (1-9) for facilitating the insertion of an external device, and a data state monitoring interface (1-10). The input end of the high-speed CAN transceiver (1-3) is electrically connected to the output end of a signal acquisition module (1-11); the signal acquisition module (1-11) is electrically connected to an electric strut motor Hall sensor (2-1), a tailgate unlocking motor Hall sensor (3-1), and a tailgate self-priming motor Hall sensor (4-1) separately; the output end of the high-speed CAN transceiver (1-3) is electrically connected to the microprocessor (1-1). The ECU control motherboard features stable performance, ease of program update, low maintenance costs, hierarchical control of the power source, stable power supply, power source reverse-connection protection, high reliability, and low failure rate.
