Abstract

A method and apparatus are provided for time-controlled activation of a vehicle function in a vehicle with automatic adjustment of the time of a vehicle-internal clock from standard time to daylight saving time and/or from daylight saving time to standard time. An operator control element is provided for manually selecting an activation instant. An electronic control unit takes the activation instant and the time of the vehicle-internal clock as a basis for prompting activation of the vehicle function when the activation instant has been reached. Selection of an activation instant that occurs only after an automatic changeover of the vehicle-internal clock from standard time to daylight saving time or from daylight saving time to standard time is to be expected prompts output of appropriate indicator.

First claim

What is claimed is:

1. An apparatus for time-controlled activation of a vehicle function in a vehicle, comprising:
a vehicle-internal clock configured for automatic adjustment due to a time standard change;
an operator control element configured to enable manual user selection of an activation instant;
an electronic control unit configured to:
receive the selected activation instant and a time of the vehicle-internal clock,
activate the vehicle function when the time of the vehicle-internal clock corresponds to the activation instant,
determine that the received activation instant will first occur after an expected automatic adjustment of the vehicle-internal clock due to the time standard change, and
output a user perceptible indicator based on the determination.

2. The apparatus according to claim 1 , wherein the operator control element that is used to manually select the activation instant is a part of a vehicle-internal or vehicle-external operator control apparatus.

3. The apparatus according to claim 1 , wherein the indicator output is a visual, audible and/or haptic indicator.

4. The apparatus according to claim 1 , wherein the indicator is output immediately after the activation instant has been selected.

5. The apparatus according to claim 1 , wherein the indicator is output at, or in proximity to, the operator control element so as to be perceivable immediately after the activation instant is selected.

6. An apparatus for time-controlled deactivation of a vehicle function in a vehicle, comprising:
a vehicle-internal clock configured for automatic adjustment of time due to a time standard change;
an operator control element configured to enable manual user selection of an deactivation instant;
an electronic control unit configured to:
receive the selected deactivation instant and a time of the vehicle-internal clock,
deactivate the vehicle function when the time of the vehicle-internal clock corresponds to the deactivation instant,
determine that the received deactivation instant will first occur after an expected automatic adjustment of the vehicle-internal clock due to the time standard change, and
output a user perceptible indicator based on the determination.

7. The apparatus according to claim 6 , wherein the operator control element that is used to manually select the deactivation instant is a part of a vehicle-internal or vehicle-external operator control apparatus.

8. The apparatus according to claim 6 , wherein the indicator output is a visual, audible and/or haptic indicator.

9. The apparatus according to claim 6 , wherein the indicator output is output immediately after the deactivation instant has been selected.

10. The apparatus according to claim 6 , wherein the indicator is output at, or in proximity to, the operator control element so as to be perceivable immediately after the deactivation instant is selected.

11. A method of operating a vehicle equipped with a vehicle-internal clock whose time is automatically adjusted due to a time standard change, and with an operator control element configured to enable manual user selection of an activation instant for a vehicle function, the method comprising the acts of:
receiving, via an electronic control unit in the vehicle, the selected activation instant for a vehicle function;
receiving, via the electronic control unit in the vehicle, a time signal from the vehicle-internal clock, wherein the electronic control unit is configured to utilize the manually selected activation instant and the time signal to activate the vehicle function when the activation instant occurs; and
outputting, via the electronic control unit in the vehicle, a user perceptible indicator upon a determination by the control unit that the activation instant first occurs after an expected automatic adjustment of the vehicle-internal clock due to the time standard change.

12. The method according to claim 11 , further comprising the acts of:
receiving, via the electronic control unit in the vehicle, a manually selected deactivation instant; and
outputting a user perceptible indicator, via the electronic control unit of the vehicle, upon a determination by the control unit that the deactivation instant first occurs after the expected automatic adjustment of the vehicle-internal clock due to the time standard change.

13. The method according to claim 12 , wherein the outputting of the indicator occurs immediately after the manually selected activation or deactivation instant has been received by the electronic control unit in the vehicle.

14. The method according to claim 13 , wherein the outputting of the indicator is carried out by providing the indicator at, or in proximity to, an operator control element perceptible at the instant the manually selected activation or deactivation instant is received.
