| 摘要 | An automotive electronic control unit configured to control an automotive electrically-actuated device which is required to move from/to one or more end-of-travel positions, wherein the electronic control unit is configured to detect reaching an end-of-travel or stall position by the automotive electrically-actuated device based on: amplitude of the electric current absorbed by the automotive electrically-actuated device,gradient of amplitude of the electric current absorbed by the automotive electrically-actuated device, andripple frequency of amplitude of the electric current absorbed by the automotive electrically-actuated device. | ||

| 主权项 | 1. An automotive electronic control unit comprising: an analog-to-digital converted (ADC) data collector module configured to receive an analog electric signal indicative of an amplitude of an electric current absorbed by an automotive electrically-actuated device; and an end-of-travel detector module configured to: receive data indicative of the amplitude of the absorbed electric current from the ADC data collector module;determine a gradient of the amplitude of the absorbed electric current;determine a ripple frequency of the amplitude of the absorbed electric current; anddetermine, based at least in part on the data indicative of the amplitude of the absorbed electric current, the gradient, and the ripple frequency, that the automotive electrically-actuated device has reached an end-of-travel position or stall position. | ||
