The invention relates to the field of new energy automobile control, and discloses a resolver signal decoding method, device, equipment and medium, the device comprises a first processing core and a second processing core, and the method comprises the following steps: obtaining a resolver recovery signal of a resolver through the second processing core, and carrying out decoding calculation on the resolver recovery signal to obtain a resolver recovery signal; decoding information is obtained; and the first processing core performs current closed-loop control on the motor according to the decoding information. The second processing core assists calculation to realize a decoding scheme and determine the decoding information, and the first processing core performs current closed-loop control based on the decoding angle in the decoding information, so that a soft decoding scheme based on dual-core communication interaction is realized, the high cost brought by a hard decoding chip is saved, the decoding difficulty is reduced, and the decoding efficiency is improved. And the dependence of the soft decoding function on the DSCADC module is eliminated.

    本发明涉及新能源汽车控制领域,公开了一种旋变信号解码方法、装置、设备及介质,所述装置包括第一处理核和第二处理核,所述方法包括:通过所述第二处理核获取旋转变压器的旋变回收信号,并对所述旋变回收信号进行解码计算,得到解码信息;所述第一处理核根据所述解码信息对电机进行电流闭环控制。本发明通过第二处理核协助计算实现解码方案确定解码信息,并通过第一处理核基于解码信息中的解码角度进行电流闭环控制,实现基于双核通信交互的软解码方案,节省了硬解码芯片带来的高昂成本,降低了解码难度,摆脱了软解码功能对DSADC模块的依赖。
