The invention relates to an inside door handle system for a door of a vehicle, wherein the door is transferable into a locking state and into an unlocked state by a closing system, comprising an actuation element for the actuation of the closing system and at least one support connectable with the door at which the actuation element is assembled, and further comprising at least a sensor element which with an approaching of an object in its recognition area transmits a recognition signal, wherein a release mode for the closing system is intended with which the closing system is in the unlocked state with which the actuation of the actuation element successively effects an opening function of the door wherein a control unit can be brought into data communication with the closing system and the sensor element, wherein in dependence on an existing recognition signal and of a vehicle related release signal the control unit transfers the closing system into the release mode.

Data acquisition and measurement acquisition device for a door handle and associated method

An operating device for a motor vehicle includes a plurality of proximity sensors for detecting contactless actuation. The operating device extends in a first plane and the sensors are disposed in that plane, separated from one another and oriented with their detection regions in the same spatial direction. A control and evaluation device is coupled to the sensors for detection of signals from each of the sensors. The sensors are covered with at least one electrically insulating plastic cover and, thus, separated from the detection region. At least one electrically conductive separating device is disposed between the sensors and oriented toward the side facing the detection regions, and directly adjacent to the plastic cover.

Operating device for motor vehicles

A sensor array for detecting the approach and movement gestures of a user at a motor vehicle includes a capacitive sensor array and at least one control device that is coupled to the sensor array and detects a change in the capacitance of the sensor array. The sensor array includes at least two sensor electrode arrays which are arranged at spatially offset positions on the motor vehicle. The sensor electrodes are configured as elongate electrode arrays and are arranged with the same spatial orientation. The control and evaluation device is designed for cyclical activation and evaluation of the sensor electrodes with changeable, electrode-specific, different cycle rates.

Capacitive sensor array and method for detecting actuation gestures at a motor vehicle

A method for detecting a function actuation on a motor vehicle with a sensor device includes monitoring the signals of a proximity sensor as to a first signal reply S. The signals of the proximity sensor are monitored for a time period Twherein the method is interrupted when the signal reply changes by more than a value Swithin the period of time T. The signal device is actuated after time Thas expired in order to signal to the user that the actuation of time has expired. The signals of the proximity sensor are monitored for time Twherein the method is continued when the signal of the proximity sensor changes by more than a predetermined value Swithin the period of time T. Otherwise, the method is interrupted. If the method is continued, the actuation of the function of the motor vehicle is detected and the function trigger is signaled to a control device in the motor vehicle.

Method for detecting a function actuation on vehicles

A method for operating a function in a motor vehicle employs a sensor arrangement with at least two spaced sensors for detecting operations caused by a user. Signals of a first sensor are monitored until a first characteristic signal answer is detected. A user-carried identification device is queried to verify authorization to access the requested function. Signals of a second sensor are monitored to determine an operation caused by approaching the second sensor. Signals from the first and second sensors are monitored for a predetermined time period t1. If the signals indicate a continued operation of the two sensors during t1, an expiration of t1 is signaled to the user. Signals of the first sensor are monitored for a predetermined time period t2. If the signal of the first sensor indicates a cancellation of the operation within t2, the function of the motor vehicle is triggered.

Detection method for operating gestures

A keyless actuating system has a switchable electrical device, a coded transponder adapted to be carried by a user, and a vehicle-mounted interrogating unit adapted when enabled to remotely coact with the transponder for switching the device when the transponder holds a predetermined code. A first capacitor element is carried on the vehicle, and a second capacitor element is carried on the user. A control circuit determines the capacitance between the first and second elements when the user is near the vehicle for enabling the interrogating unit only when the capacitance between the first and second elements passes a predetermined threshold. Normally the second capacitor element is actually the user.
