The invention relates to a method for determining a fault in an electronically commutated electric motor, in which at least one stator coil of the electric motor is connected in parallel in each motor phase, in which a motor phase is energized and the current flowing through this motor phase is measured. In a method in which a defect in the electric motor is identified reliably, the three motor phases are energized one after the other and the current occurring during this energization of the individual motor phases is measured, wherein the currents measured in the three motor phases are compared with one another and a defect in the electric motor is identified if the measured currents differ from one another.

Method for determining a fault in an electronically commutated electric motor

A device has a measuring device, in particular an alcohol-measuring device (), for measuring the state of intoxication of a test subject and for generating a corresponding measured value. A camera () is provided for recording an image with the face of the test subject. A control unit () is configured to store the measured value together with the image in a memory unit (). An analyzer () is configured such that the analyzer can identify a face and/or a defined, fixed pattern in the image. A follow-up action is triggered by the analyzer () when a face and/or pattern could not be identified.

In a clutch which is impelled by an actuator into the closed position and which automatically moves into the open position by an opening spring, the movement of the clutch into the open position is monitored and any malfunction is displayed.

Process and device for monitoring the operation of a clutch moved by an actuator into the closed position and automatically moving into the open position

A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.

Clutch actuator and method for the control thereof

A device for preventing a vehicle from being started includes a breath gas analyzer (), which is arranged within the vehicle and is designed to detect the breath alcohol content of an operator. A repeated test can be performed, without compromising the operator, with a control unit (), which is connected to the breath gas analyzer (), a motion sensor () and an ignition system () of the vehicle, to request a breath alcohol test at presettable times tin such a way that the breath alcohol test is performed with the vehicle stopped. The control unit () is also designed to preset, beginning from the time t, a time interval as a latency period twithin which the vehicle must be stopped.

The invention relates to a smart actuator for actuating a clutch having a communication interface for connecting to a higher-level control unit, and at least one data line for connecting to the higher-level control unit, where the smart actuator is configured to identify errors in the higher-level control unit and/or an assigned second smart actuator, and where the smart actuator has controlling means that are suitable for converting the controlled system into a safe system state in the case of a recognized error. Furthermore, the invention relates to a corresponding control method and a control system in which the smart actuators and the method are used.

Passive safety switch

A process and device for controlling a motor vehicle with an initialization device () for startup and a clutch actuated by means of a clutch actuator set () between a drive unit and a gear with a control device () by means of which at least one control of the clutch actuator set () and an acquisition of measurement data of a sensor () takes place for the purpose of determining the position of the clutch, characterized in that to verify the state 'clutch open' upon startup, a positioning of the clutch actuator set () that has been set and stored before or during shutdown is compared to a positioning that was acquired during a predetermined movement course of the clutch actuator set () after startup by means of a distance measurement, which takes place at least in a segment of that movement course, whereby the state 'clutch open' is recognized, in particular, when the magnitude of the comparison is within a predetermined tolerance range. By means of the invention one can further reduce the probability of the setting into motion of a motor vehicle after startup, which is critical in terms of safety.

Starter release

An interlock system () for a vehicle is provided with an alcohol tester (), which is designed to measure the alcohol level of a driver of the vehicle. A control device () is coupled with the alcohol tester () and is designed to make it possible to start the vehicle or to prevent the vehicle from being started depending on the measured alcohol level. A transceiver module () is coupled with the control device () and is designed to send data to a remotely located control system in a wireless manner or to receive data from said control system in a wireless manner. The transceiver module () is designed, furthermore, to release the control device () in response to data received in a wireless manner in order to make it possible to start the vehicle regardless of the operating state of the control device.

A process and device for the currentless referencing of a clutch position in non self-locking clutch actuating systems which are switched without current for a first predetermined, passive period of time or until an actuator standstill occurs, in order to verify a clutch reference position, then the clutch position achieved is determined by first measurement and current is supplied to the clutch actuating system for a predetermined, active period of time, the clutch actuating system being then switched again without current for another predetermined, passive period of time or until an actuator standstill occurs, the clutch position being determined by another measurement; finally the measured clutch position is checked to determine whether it can be verified as a new clutch reference position.

Clutch reference position

An actuator for a clutch or gear mechanism in a motor vehicle comprises an electric motor and an incremental encoder. The encoder comprises a position measurement signal output at which a position measurement signal can be output which has a number of different signal states, each of which is assigned to a relative position between a primary part and a secondary part of the electric motor. For the commutation of the electric motor, the position measurement signal output is connected to a position measurement signal input of a control device for a motor winding of the electric motor. The control device comprises a device for checking the plausibility of the position measurement signal and is designed in such a manner that on the occurrence of an implausible signal state the power supply to the electric motor is disconnected and/or the power of the electric motor is limited.

Actuator for the actuation of a clutch and/or a gear mechanism

To improve the safety of automated gearboxes, it is proposed that terminal positions of internal gearshift members and external actuation members be so defined separately from each other that one can recognize whether the engagement of a speed is accompanied by the attainment of a terminal position of an internal gearshift member or an external actuation member. Error analysis is possible in this way. For dual clutch gears, it is additionally proposed that one can, at least in gearshift operations that are critical in terms of safety, disengage on speed of a subgear in a separate procedure, before a new speed of this subgear can be engaged.
