Device and method for the reliable detection of wakeup events in the shutdown phase of a control unit
First Claim
1. A wakeup logic element for providing reliable detection of a wakeup event in a shutdown phase of a control unit for a vehicle, comprising:
- a wakeup source input, which includes a flank-sensitive wakeup input, wherein an on/off state of a vehicle control unit is controllable by the wakeup source input;
wherein a wakeup signal, which arrives at the wakeup source input during a shutdown process of the control unit, is able to be delayed or temporarily suppressed, such that the wakeup signal is applied at the wakeup source input following a completed shutdown of the control unit.

Abstract
A wakeup logic element for providing reliable detection of wakeup events in the shutdown phase of a control unit for a vehicle, having a wakeup source input, the wakeup source input being implemented as a flank-sensitive wakeup input, and an on/off state of a vehicle control unit being controllable by the wakeup source input, wherein a wakeup signal which arrives at the wakeup source input during a shutdown procedure of the control unit is able to be delayed or temporarily suppressed, such that the wakeup signal is applied at the wakeup source input after the control unit has been shut down.

8. A motor vehicle, comprising:
-
at least one of the following; (i) at least one wakeup logic element for providing reliable detection of a wakeup event in a shutdown phase of a control unit for a vehicle, including; a wakeup source input, which includes a flank-sensitive wakeup input, wherein an on/off state of a vehicle control unit is controllable by the wakeup source input; wherein a wakeup signal, which arrives at the wakeup source input during a shutdown process of the control unit, is able to be delayed or temporarily suppressed, such that the wakeup signal is applied at the wakeup source input following a completed shutdown of the control unit; and (ii) a control unit, including; a wakeup logic element for providing reliable detection of a wakeup event in a shutdown phase of a control unit for a vehicle, including; a wakeup source input, which includes a flank-sensitive wakeup input, wherein an on/off state of a vehicle control unit is controllable by the wakeup source input; wherein a wakeup signal, which arrives at the wakeup source input during a shutdown process of the control unit, is able to be delayed or temporarily suppressed, such that the wakeup signal is applied at the wakeup source input following a completed shutdown of the control unit.

9. A method for providing a reliable detection of a wakeup event in a shutdown phase of a control unit, the method comprising:
-
detecting a scheduled shutdown process of a control unit; suppressing a possible wakeup signal until the end of the shutdown process of a control unit; and canceling the suppression of the possible wakeup signal. - View Dependent Claims (10)
