摘要
介绍了CAN总线下载技术在新能源汽车电机控制器程序升级中的应用,该应用是基于德州仪器公司的数字信号处理器TMS32OF2812芯片实现的。由于CAN总线具有很强的抑制共模干扰的能力,再加上本技术中使用的数据校验和重发机制,使得其稳定性和可靠性大大加强,这种方法非常适用于车载控制器的远程控制和升级,具有较大的实用价值。
Application of CAN bus download technology in new energy motor controller pro- gram updating is introduced, which is realized based on DS processor TMS32OF2812 of TI Corp. Since the CAN bus has a strong common mode interference rejection capability, coupled with data validation and retransmission mechanisms used this technique, its stability and reliability is greatly enhanced. This method is very suitable for vehicle control remote control and upgrading, and has great practical value.
