Abstract

A servo system and an actuating method for adjusting a vehicle window that can be adjusted with a servomotor. For the sake of improved driving comfort, to permit adjustment of the vehicle window with a sensor, a measurement volume which adjoins the vehicle window in the passenger compartment of a vehicle is monitored for the presence of a body part of a vehicle occupant and/or the presence of a lighted cigarette. The vehicle window is lowered here from its closed position by a portion of its actuating path if the presence of a body part or the presence of a burning cigarette is detected in the measurement volume.

Claims

1. In a vehicle having a vehicle window that is adjusted by an actuating motor between a closed position, a fully open position, and partially open positions therebetween, an actuating method for adjusting the vehicle window, the method comprising:

providing a sensor inside a passenger compartment of the vehicle and in vicinity of the vehicle window;

monitoring a measurement volume which adjoins the vehicle window and the sensor in the passenger compartment of the vehicle with the sensor, for a presence of a body part of a vehicle occupant or for a presence of a lighted cigarette; and

when the presence of the body part or the presence of the lighted cigarette is detected by the sensor in the measurement volume, causing the actuating motor to move the vehicle window from the closed position to a partly open position by moving the window from the closed position to the partly open position.

2. The actuating method according to claim 1, which comprises lowering the vehicle window only if a predefined additional criterion is satisfied when the body part or the lighted cigarette is detected.

3. The actuating method according to claim 2, wherein the additional criterion is that the presence of the body part or the lighted cigarette is detected within a predefined time window opened by an activation of a switch.

4. The actuating method according to claim 2, wherein the additional criterion is that smoke is detected by a smoke detector.

5. The actuating method according to claim 1, which comprises detecting a measured temperature variable with a sensor, detecting the presence of the body part or the presence of the lighted cigarette in the measurement volume if the detected measured temperature variable exceeds a predefined temperature threshold.

6. The actuating method according to claim 1, which comprises evaluating a measured variable detected by the sensor with respect to a movement pattern of the body part, and wherein the additional criterion is that a predefined movement pattern is detected on the basis of the measured variable.

7. In combination with a vehicle having a vehicle window that is adjusted by an actuating motor between a closed position, a fully open position, and partially open positions therebetween, a positioning system for the vehicle window, the positioning system comprising:

a sensor attached to the vehicle inside a passenger compartment in vicinity of the vehicle window of the vehicle and disposed to monitor whether or not a body part of a vehicle occupant or a lighted cigarette is present in a measurement volume that adjoins the vehicle window and said sensor; and

a control unit connected to said sensor and to the actuating motor which adjusts the vehicle window, said control unit;

monitoring the measurement volume adjoining the vehicle window with said sensor which detects a presence of the body part of the vehicle occupant or for the presence of the lighted cigarette; and

when the presence of the body part or the presence of the lighted cigarette is detected in the measurement volume, causing the actuating motor to lower the vehicle window from the closed position to a partly open position between the closed position and the fully open position.

8. The positioning system according to claim 7, further comprising a switch connected by circuitry to said control unit, for activating said sensor during a predefined time window.

9. The positioning system according to claim 7, further comprising a smoke detector for detecting smoke connected by circuitry to said control unit, in order to activate said sensor.

10. The positioning system according to claim 7, wherein said sensor is at least one sensor selected from the group consisting of a capacitive proximity sensor, an optical movement sensor and an infrared sensor.
