    摘要: 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.

    摘要: A work vehicle with a hydrostatic steering system is disclosed which is capable of performing optimum control of the absorption torque of a hydraulic pump according to running load; capable of preferentially ensuring turning performance and implement speed when running load is relatively low; and capable of ensuring desired turning performance even when running load is relatively high. To this end, a bulldozer with a hydrostatic steering system, wherein the power of a hydraulic motor driven by pressure oil fed from a hydraulic pump operated by an engine is transmitted to right and left crawler tracks through a differential steering means composed of planetary gear trains etc., is designed to control the absorption torque of the hydraulic pump according to the speed ratio of a torque converter calculated by a speed ratio operation unit.
