CANape中的Scripts，个人理解其功能在于特定条件自动运行，优势在于提升效率，例如车辆放置于环境温仓，每隔1h后判断环境温度达到限值-30℃，进行自动启机并记录5次启机时间。相关分享内容根据帮助文件编制，仅做提供思路和格式之用。

脚本文件已测试，通过Compile，但未使用HCU调试。

2 硬件

文中涉及的相关部件原理，参考文库“BorgWarner DCT Electrohydraulic Controls Ritschel” 中的知识点，内容如下：

3 功能

思路为电磁阀Sweep测试（0-1000mA-0，步长100mA）测试，然后Step（0→1000mA），最后进行Sweep复测，对应的图表如下：

4 源程序

脚本内容如下：

运行脚本时注意全局变量的设置，此处不多叙述。
