摘要： In a method for detecting the status of the clutch in the drive train of a motor vehicle, the engine speed and the speed are ascertained and a transmission ratio is formed as the quotient of the engine speed and speed. Furthermore, a reference value is determined, which is set equal to the transmission ratio iges from a first time step. In a subsequent time step, the difference between the instantaneous transmission ratio iges and the reference value is formed, a disengaged clutch status being detected if the difference exceeds a threshold value.

摘要： A method and device for driving a pump of a brake system, in which a pump motor achieves full drive for a particular time following a braking request from the brake system. During the subsequent clocked driving action, a drive signal is subjected to a pulse width modulation based on a direct comparison between a motor voltage and a voltage threshold value. Due to a subsequent comparison between the motor voltage and a safety threshold, and the resulting full drive for the particular time, an increased load on the pump causes the pump to produce the necessary delivery capacity. In addition, a selectable maximum off-time of the pump motor guarantees a minimum pump on-time per drive cycle. The pump can be made to achieve full drive prematurely as a function of certain conditions which can be subjected to a preventive check, thereby avoiding an excessively high load. It is also possible to coordinate the way in which different control strategies access the pump.
摘要翻译：一种用于驱动制动系统的泵的方法和装置，其中泵马达在来自制动系统的制动请求之后达到特定时间的全驱动。在随后的时钟驱动动作期间，基于电动机电压和电压阈值之间的直接比较对驱动信号进行脉宽调制。由于电机电压和安全阈值之间的后续比较以及在特定时间内产生的全驱动，泵上的负载增加导致泵产生必要的输送能力。此外，泵电机的可选最大关闭时间保证每个驱动循环的最小泵接通时间。可以根据能够进行预防性检查的某些条件的功能，使泵过早地实现全驱动，从而避免过高的负载。也可以协调不同控制策略访问泵的方式。

摘要： A method and a system for limiting an engine torque of vehicles to a maximum value. In the method, signals representing wheel torques from wheel sensors at the drive train are acquired, the wheel torques, differentiated according to driving situations which can have a harmful influence on the transmission, differential or torque converter, then being checked for a wheel-torque value which is too high. If too high a value is found, the engine torque is limited or reduced.
