Abstract

A vehicle control system for an automatically opening and/or automatically closing flap, includes a programmable operating switch and a programmable electronic control device. The operating switch is a proximity sensor that is actuatable in a non-contact manner and, after the actuation occurs, generates an operation request signal as an input signal to the control device. In the presence of the operation request signal and, as required, of at least one further condition, the control device emits a command to a closing mechanism for opening or closing the flap. The control device and/or the operating switch is programmed such that the operation request signals are counted as long as at least a first defined condition has not yet been met, and that, when a defined maximal counter reading has been reached, the operation request signals will be ignored until at least a second defined condition has been met.

Claims

1. A control system for a vehicle having an automatically opening and/or closing flap, the control system comprising:

a programmable electronic control device;

at least one programmable operating switch, the operating switch being a proximity sensor actuatable in a non-contact manner wherein, after actuation occurs, the operating switch generates an operation request signal as an input signal to the control device;

wherein the control device is operatively programmed such that, in an event of receipt of the operation request signal and, as required, at least one further condition, the control device emits a command for opening or closing the flap;

further wherein at least one of the control device and the operating switch is operatively programmed such that operation request signals are counted as long as at least a first defined condition has not yet been met, and still further wherein when a defined maximal counter reading is reached, the operation request signals will be ignored until at least a second defined condition has been met.

2. The control system according to claim 1, wherein the first defined condition is an absence of the operation request signal during a first predefined time period from an occurrence of a previous operation request signal.

3. The control system according to claim 1, wherein the first defined condition is a presence of a defined condition signal of a vehicle closing system.

4. The control system according to claim 2, wherein another first defined condition is a presence of a defined condition signal of a vehicle closing system.

5. The control system according to claim 1, wherein the second defined condition is a course of a second predefined time period or a presence of a defined condition signal of a vehicle closing system or a start of an internal-combustion engine.

6. The control device according to claim 1, wherein the second defined condition is equal to the first defined condition.

7. The control device according to claim 1, wherein at least one of the control device and the proximity sensor is operatively programmed such that, during a course of a first defined time period starting from an occurrence of the operation request signal, as long as at least a first defined condition has not yet been met, whether an additional operational request signal is occurring is determined and, if the additional operation request signal is occurring, a counter reading is increased, and the first defined time period is restarted until a maximal defined counter reading has been reached.

8. The control system according to claim 1, further comprising a closing mechanism operatively configured to open or close the flap, wherein the command from the control device actuates the closing mechanism.
