Abstract

A method for providing operationally safe activation of at least one electronic component in a system, a start process of the system being initiated, a decision logic being activated, at least one temperature sensor being read out by the decision logic, the decision logic, based on the measured temperature of the at least one temperature sensor, checking whether the at least one electronic component is activatable in an operationally safe manner, and an activation of the at least one electronic component being initiated by the decision logic, if the temperature measured by the at least one temperature sensor is below a threshold value. A related system is also described.

First claim

What is claimed is:

1. A method for providing operationally safe activation of at least one electronic component in a system, the method comprising:
initiating a start process of the system;
activating a decision logic;
reading out at least one temperature sensor while the at least one electronic component is in a deactivated state;
performing a check by the decision logic based on a measured temperature of the at least one temperature sensor, whether the at least one electronic component is activatable in an operationally safe manner; and
initiating an activation, from the deactivated state, of the at least one electronic component by the decision logic, in response to determining that the temperature measured by the at least one temperature sensor is below a threshold value.

2. The method of claim 1 , wherein when the threshold value of the measured temperature of the at least one temperature sensor is exceeded, the activation of the at least one electronic component is suspended by the decision logic until the measured temperature is below the threshold value.

3. The method of claim 1 , wherein a self-test is carried out by the decision logic.

4. The method of claim 1 , wherein an electronic test of the at least one electronic component is carried out by the decision logic.

5. The method of claim 1 , wherein the decision logic checks whether the at least one temperature sensor exhibits an error.

6. The method of claim 5 , wherein a restart of the system is initiated by the decision logic or an error message is generated when the error of the at least one temperature sensor is detected by the decision logic.

7. The method of claim 1 , wherein the at least one electronic component is activated by the decision logic in a power saving mode when a first threshold value of the measured temperature is exceeded and a second threshold value of the measured temperature is fallen below.

8. The method of claim 1 , wherein a self-heating of the at least one electronic component is taken into consideration by the decision logic when carrying out the check.

9. The method of claim 1 , wherein the at least one electronic component is a control unit.

10. The method of claim 1 , wherein the at least one electronic component is a video control unit.

11. A system, comprising:
at least one electronic component and at least one decision logic for checking and for initiating an activation of the at least one electronic component;
wherein the at least one electronic component is activatable by the decision logic during a system start when an operationally safe general condition for the at least one electronic component exists, and
wherein the at least one electronic component and the at least one decision logic are configured to perform the following:
initiating a start process;
activating the decision logic;
reading out at least one temperature sensor while the at least one electronic component is in a deactivated state;
performing a check by the decision logic based on a measured temperature of the at least one temperature sensor, whether the at least one electronic component is activatable in an operationally safe manner; and
initiating the activation, from the deactivated state, of the at least one electronic component by the decision logic in response to determining that the temperature measured by the at least one temperature sensor is below a threshold value.

12. The system of claim 11 , wherein the at least one temperature sensor includes at least one internal temperature sensor.

13. The system of claim 11 , wherein the decision logic is electronically connected to at least one external temperature sensor.

14. The system of claim 11 , wherein the decision logic is configured as an integrated circuit, a microcontroller or a Power Management Integrated Circuit (PMIC).
