Automotive controller based on block gateway electronic control unit

Abstract

The invention discloses an automobile controller based on a block gateway electronic control unit, which includes a block gateway electronic control unit ring-shapedly deployed at different positions of the vehicle body with the automobile Ethernet TSN as the backbone network; the block gateway electronic control unit includes an automobile Processor and FPGA; the automotive processor collects external sensor data, performs fusion calculations, and makes judgments and checks on the calculation results; the automotive processor connects to the FPGA through the PCIE interface for high-speed data exchange. The electronic control unit of the block gateway of the present invention is deployed in different positions of the vehicle body, and an automotive processor with sufficient computing power is used. When a functional safety defect occurs, the vehicle control will preferentially exit the automatic control mode, and take reasonable emergency braking, etc. remedy. The export direction of the signal is bridged at any time through the FPGA, which provides convenience for the electrical wiring of the vehicle after the block gateway electronic control unit is deployed to different positions of the vehicle body.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to an automotive controller based on a block gateway electronic control unit. Background technique [0002] As the automotive electronic and electrical architecture becomes more complex and the data bandwidth increases, it has been several years of development from the "node" architecture to the "domain" architecture. In production practice, due to the continuous addition of new functions, countless new electronic controls have been added accordingly. Unit ECU, with the continuous increase of ECUs over time, the "domain" architecture has become very complex and bloated, resulting in the network harness used for the "domain" architecture usually developing the third heaviest and expensive in the overall vehicle cost components, with a maximum weight of 50kg and a total length of up to 5km. [0003] Today's autonomous driving trend will add more ECUs and sensors, further increas...
