Description

Technical Field

[0001] The utility model relates to the technical field of vehicle control, in particular to a vehicle-mounted universal controller. Background Art

[0002] Existing vehicle controllers are designed for specific vehicle models or functions. The controller casing is mostly made of metal, which is conducive to improving heat dissipation and protection performance. Connectors are left on the surface of the controller for signal input and output and communication between different controllers. Different controllers have different functions, so the size, shape, connector type and some performance indicators are different. The electromagnetic compatibility and environmental adaptability meet the national standards. In general, controllers with specific functions are only suitable for this control system.

[0003] Existing on-board controllers are only targeted at specific vehicle models or functions, lack versatility and flexibility, resulting in difficulty in interchangeable controllers and functional upgrades between different vehicle models, increasing manufacturing costs and maintenance difficulties, and having certain functional limitations; at the same time, in harsh operating environments, such as extreme cold, plateaus, and strong electromagnetic interference environments, performance indicators are more stringently required, and current controllers are mostly civilian-grade and cannot meet special indicator requirements; existing on-board controllers can only support limited communication protocols (such as LIN, CAN). With the development of vehicle intelligence and networking, the on-board data communication load rate is getting higher and higher, and traditional communication methods limit the communication capabilities between vehicles and external devices and other vehicles; and existing vehicle controllers did not fully consider expansion and upgrade needs during design, and cannot adapt to new functions and requirements, requiring the entire controller to be replaced or complex modifications to be performed.
