20090293361 | ADJUSTMENT OF A MOTORIZED POSITIONING DEVICE - A method for calibrating a powered actuator for use in a vehicle is provided, with regard to an end position of an actuating element which is easy to achieve and conserves easily damaged mechanical components of the actuator made from plastic, rubber or similar. According to an example embodiement, in a calibrating step, the actuator is operated with recording and analysis of an actuation speed measured parameter such that the actuating element is moved in the direction of the end position and reaching the end position is recognized when the value of the actuation speed measured parameter reaches or drops below a given threshold. A temperature parameter characterizing the temperature of the actuator is evaluated before or during the calibration process. The calibration step is then only carried out if the value of the temperature parameter does not exceed an upper temperature limit. An actuator suitable for carrying out said method is also disclosed. | 12-03-2009 |

A wake-up operator control event is detected by a sensor and has an associated time interval from the preceding wake-up operator control event. The time interval is ascertained when a wake-up operator control event is detected, and the control unit is woken up or not woken up. Each wake-up operator control event has an associated switch-off indicator which is ascertained each time a wake-up operator control event is detected, and the control unit is woken up or not woken up as a function of the level of the switch-off indicator with reference to a switch-off threshold. A change in the current switch-off indicator relative to the preceding switch-off indicator is all the greater the smaller the current time interval. | 01-17-2013 |
20130131917 | METHOD FOR THE SENSOR DETECTION OF AN OPERATOR CONTROL EVENT - A method for detection of a control event by a sensor arrangement having at least one sensor element and a sensor controller is described. The sensor controller digitizes sensor signals into sensor measured values. An operator control event is produced by a user and a first coarse evaluation for a sign of operator control is performed and a predetermined number of sensor measured values are progressively buffer-stored in a buffer store wherein detection of a sign of operator control initiates a fine evaluation of the sensor measured values to verify the occurrence of an operator control event at an initiation time. The fine evaluation is based on the buffer-stored sensor measured values and on subsequent sensor measured values, so that the fine evaluation includes sensor measured values both before and after the initiation time. | 05-23-2013 |
20130271059 | PRECISE ASCERTAINMENT OF ACTUATING POSITION FOR A MOTOR-DRIVEN VEHICLE PART - In order to ascertain the actuating position of a vehicle part that is moved by an electric actuating motor via an actuating mechanism, an angle of rotation correlating with the number of motor shaft rotations during the actuation process or a motor signal correlated therewith are ascertained during an actuation process. An actuating position measure for the actuating position of the vehicle part is derived from the angle of rotation or the motor signal correlating therewith. During this process, an unloaded angle of rotation, through which the motor shaft rotates during an initial no-load phase of the actuation process without motion of the vehicle part is compensated by a predetermined correction term. The correction term is changed according to a stored dependency on a characteristic quantity for the age of the actuating mechanism. | 10-17-2013 |
20140324273 | METHOD FOR GENERATING AN OPERATOR CONTROL MESSAGE WHEN AN OPERATOR CONTROL EVENT OCCURS - The invention relates to a method for detecting an operator control event using a sensor arrangement having at least one proximity sensor and a sensor controller, the operator control event being generated by a user of a vehicle. A first coarse evaluation of the sensor measured values for the occurrence of an operator control sign is carried out, that a predetermined number of the respective last sensor measured values of at least one sensor element are buffered, that the detection of an operator control sign triggers a fine evaluation of the sensor measured values for verifying the occurrence of an operator control event at a triggering time, and that the fine evaluation is based on the buffered sensor measured values and on the temporally subsequent sensor measured values, with the result that sensor measured values both before and after the triggering time are included in the fine evaluation. | 10-30-2014 |
20150077141 | Capacitive sensor for an anti-collision apparatus, and capacitive sensor - A capacitive sensor is configured for detecting an object, in particular for detecting a collision in the case of a movable vehicle part, and an anti-collision apparatus has such a sensor. The sensor has an electrode arrangement with at least one transmitting electrode and at least one or more receiving electrodes. The sensor has a signal generation circuit which is connected upstream of the at least one transmitting electrode.
