METHOD AND DEVICE FOR CONTROLLING A MOTOR VEHICLE DRIVE TRAIN
摘要
<p>A method and a device for controlling a motor vehicle drive train determine the direction of rotation of the drive train by evaluating sensor signals of a first sensor unit on the output side of the drive train. The first sensor unit includes a sensor wheel fastened to a rotatable component on the output side of the drive train and two rotational speed sensors which are fixed with respect to a housing and are placed circumferentially next to one another. In order to speed up the determination of the direction of rotation, the sensor signal of a second sensor unit on the input side of the drive train is evaluated. The second sensor unit includes a sensor wheel that is fastened to a rotatable component on the input side of the drive train and a rotational speed sensor that is fixed with respect to the housing.</p>
