Embodiment Construction

[0011] Such as figure 1 As shown, the automotive exterior light controller is mainly composed of CAN bus transceiver 1, LIN bus transceiver 2, sunlight sensor 5, voltage regulator 3, main control unit 6, drive unit 9, solenoid valve 8 and triode overcurrent protection circuit 7 composition. The main control unit 6 adopts a ST72561AR single-chip microcomputer; the CAN transceiver 1 adopts the TJA1040 chip of PHILIPS to receive and send CAN messages; the LIN transceiver 2 adopts the TJA1020 chip of PHILIPS to receive and send LIN signals ; The voltage regulator 3 adopts the L4987C chip to convert the power supply and provide the required 5V power supply for the main control unit. The drive unit 9 adopts a V23084-C2001-A303 relay circuit.

[0012] The CAN transceiver TJA1040 is connected to the main control unit through the CAN_H, CAN_L PIN on it; the LIN transceiver TJA1020 is connected to the main control unit through the LIN PIN on it; the voltage regulator L4987C is connect...

Abstract

The invention relates to a vehicle external modulation controller based on a CAN bus and an LIN bus, comprising a bus receiver used for converting CAN bus protocol, a bus receiver used for converting LIN bus protocol, a solar sensor, a voltage stabilizer, a main control unit, a driving unit and a triode overcurrent protection circuit. Because the invention adopts the control strategy based on the CAN bus and the LIN bus, not only the vehicle external modulation can be controlled integrally, but also the wiring harness can be reduced appropriately; in addition, the failure of the vehicle external modulation can be stored and read and better matched with other nods of the whole vehicle to improve the stability of the whole vehicle.

Description

technical field [0001] The invention relates to the technical field of automobile exterior lamp control, in particular to an automobile exterior lamp controller based on CAN and LIN buses. Background technique [0002] At present, most automobiles have realized the integrated electronic control of external lights and other loads, but most of them use switches for direct control, resulting in many wiring harnesses and difficult maintenance. [0003] CAN (abbreviation of Controller Area Network) local area control network is a serial communication protocol that can effectively support distributed real-time control with a high level of security. CAN was originally developed by the German Bosch company in the 1980s, and has now been standardized by the International Organization for Standardization and other standardization organizations (ISO11898, SAEJ1939). The CAN bus has a wide range of applications, from high-speed networks to low-cost multi- CAN can be used for wiring. I...
