摘要: The invention discloses a small-sized electric control gasoline engine touching-type HMI calibration method based on CAN bus. Calibration system development content comprises an upper host software and lower ECU module. A controller local area network (CAN) bus technology is applied hardware platform to achieve communication. carries out with man-machine interaction device (HMI) as carrier. main chip selects Freescale MC9S12P128. edition employs Kinco company configuration editing for design, CANopen custom protocol applied, the has functions of real-time monitoring operation parameters, fault diagnosis communication, on-line calibration, data storage like. communication basis achieving protocol, redistribution memory resources premise MAP erasing, Flash erasing function.
