Automobile intelligent instrument system with CAN communication

The utility model provides an automotive intelligent instrument system with CAM communications. Based on the traditional combination instrument, the utility model is newly provided with a single-chip system, a CAN bus and a liquid crystal display system; the single-chip system is respectively connected with the combination instrument and the liquid crystal display system through the signal output terminal; the signal input terminal of the single-chip system is connected with the CAN bus through a CAN controller; the microprocessor is provided with an embedded real-time operating system. The microprocessor of the automotive intelligent instrument system is communicated with other main automotive electronic control units for receiving various signals through the CAN bus, after being processed, the signals are transferred to the liquid crystal display system or the combination instrument; the signals without affection to the running of the vehicle are connected with the combination instrument through signal lines, thereby the utility model can solve problems that more wiring harnesses in the prior automotive combination instrument, which can not meet the complex operating condition requirements of the modern vehicle. The utility model is suitable for electric vehicle and hybrid vehicle.
