Method for safe determination of speed of motor vehicle, involves carrying out with two courses with speed ratios, and number of revolutions of two input shaft are determined by two input shaft sensors

摘要

The method involves carrying out with two courses with the speed ratios. The number of revolutions of two input shafts (6,7) are determined by two input shaft sensors (EWS1,EWS2). The provided values are compared with one another, and a faulty sensor is identified on the basis of comparisons from two of the three values.
