摘　　要：工程车辆控制器中各种带ISP功能的元件的大量使用,使得控制器具有利用CAN总线进行现场升级的能力。在讨论利用CAN总线对车辆控制器进行现场升级的模式以及通信协议后,以基于ISP的车载设备作为升级实验对象验证了利用CAN总线升级车辆控制器的正确性与可行性。Using the ISP （In-System Programmability） component in embedded device makes it have the capability to perform upgrade with CAN-bus. Based on discussing the communication protocol of the upgrade of embedded controller for construction vehicles, the upgrade model about controller for construction vehicles is suggested. By acting the CAN-based used controller for construction vehicles as the upgrade experiment object, and explaining the upgrade scheme and the communication protocol in detail, the correctness and feasibility of independent upgrade model are validated.
