    摘要： A device for controlling a steer-by-wire steering system in a vehicle, in which redundantly generated sensor signals for regulating a steering motor and for a feedback actuator that transfers the restoring torques from the road to the driver via the steering wheel are received by a control device and plausibility checks of the sensor signals are performed therein and in an operatively associated monitoring module. Microcomputer module and monitoring module monitor each other reciprocally. An auxiliary level for the SbW steering system is monitored by the control device which, in the case of error, switches to this auxiliary level or a mechanical auxiliary level. To further increase safety, the steering wheel motor is triggered via control signals for its phase currents and by a steering wheel motor enable signal, and the steering motor is triggered via control signals for its phase currents and via a steering motor enable signal.

    摘要： A steering system for a vehicle, having a steering wheel, a steering gear and a steering module, disposed between them, for superimposed steering engagement by a controlled electric motor. The electric motor has an input shaft connected to the steering wheel and an output shaft connected to the steering gear. For the sake of structurally simplifying the steering module, the electric motor is in direct engagement, in line with a clutch that can be engaged and disengaged, with the input shaft via a first gear, and the electric motor is in direct engagement with the output shaft via a second gear.

    摘要： The invention is directed to a system for determining gear ratio change in an automatic transmission in a vehicle having an accelerator pedal actuated by a driver of the vehicle. The system includes a first sensor for detecting the position (DK) of the accelerator pedal as a first variable and a second sensor for detecting the straight-line speed (V.sub.x) of the vehicle as a second variable. An adaptation variable (BZ) is determined in dependence upon at least one of the following: the instantaneous driving behavior of the driver, the environmental conditions to which the vehicle is subjected and the driving situation in which the vehicle is. A gear ratio change function includes a characteristic field for receiving the first and second variables (DK, V.sub.x) as first and second input variables (DK, V.sub.x), respectively. At least one of the first and second input variables (DK, V.sub.x) is changed in dependence upon the adaptation variable (BZ). The characteristic field is used to determine the gear ratio change in dependence upon said adaptation variable (BZ).

    摘要： The speed to be measured, either engine speed or vehicle (drive wheel) speed, is measured by a tachogenerator which trips a timer to provide a series of measurements. When the system is in use, a driver can store the actual speed at a selected moment as the desired speed. From a linearized model of vehicle speed or engine speed response to acceleration or deceleration of the engine by displacement of a control member, system parameters a.sub.1 and b.sub.1 are derived. The actual speed signal is multiplied by a.sub.1 and added algebraically (to produce a difference signal) to the desired speed signal, with the resulting signal then being multiplied by another constant derived from the system parameter b.sub.1 by reference to weighting factors p and q of a cost minimizing equation relating to the relative significance of obtaining a small control deviation and of limiting or increasing the amplitude of the control signal. An output signal is then provided by the second multiplying stage. The system can be constituted in an analog fashion or it may operate digitally by means of a microprocessor. Smoothing of the input and output signals may be provided by low-pass filtering in the analog case and by providing a moving average with the preceding value in the digital case. This type of regulation, which may be referred to as cyclic or as single-step control, assures an aperiodic run-in characteristic and is stable in all speed ranges.
