The invention provides a current feedback method and
system, a vehicle-mounted
electronic controller and a storage medium, and the method comprises the steps: selecting a part of channels from a target
chip to form current feedback channels, selecting one channel from the current feedback channels as a target channel, and when the current calculation of the target channel is not completed, executing the step 1; taking a current value obtained by
polling of a previous communication period as a calculation current of a target channel, keeping a
polling pointer unchanged, and pointing to the target channel; or, when it is judged that current calculation of the target channel is completed, the calculation current of the target channel is obtained, the
polling pointer is updated, and the next channel is selected from the current feedback channels to continue polling; and when feedback current of at least one channel in the current feedback channels is obtained, current feedback is directly carried out. According to the method, fixed
recovery of current of some channels is realized in a
recovery channel selection mode, current feedback can be carried out after calculation of part of channels in a target
chip is completed, and the current feedback time is shortened.
