An improved protection mechanism to protect from unintended execution of critical tasks operates, in one example embodiment, by receiving a request to start a task by a first process. The first process informs a second process of running an algorithm to verify the legitimacy of the received request
An improved protection mechanism to protect from unintended execution of critical tasks operates, in one example embodiment, by receiving a request to start a task by a first process. The first process informs a second process of running an algorithm to verify the legitimacy of the received request to determine the need to start the task. The second process stores the information regarding the starting the algorithm by the first process. The first process runs the algorithm to verify the legitimacy of the received request, and conveys an outcome of the verification to the second process. The second process enables the start of the task by the first process based on the outcome of the verification and a checking of the stored information and the first process starts the task.

A vehicle securing system in accordance with claim 1, including an indicator for providing to the driver a signal indicative of engagement within the transmission of the selected gear. 4. A vehicle securing system in accordance with claim 3, wherein the indicator is an acoustical indicator. 5. A vehicle securing system in accordance with claim 3, wherein the indicator is a visual indicator. 6. A vehicle securing system in accordance with claim 2, wherein the predetermined time interval is about 10 seconds. 7. A vehicle securing system in accordance with claim 1, wherein the control device is activated after ignition shutoff by the actuation of a brake pedal. 8. A vehicle securing system in accordance with claim 1, wherein the clutch is disengaged during the time gear engagement within the transmission takes place. 9. A vehicle securing system in accordance with claim 1, wherein the ignition switch is switched off through an ignition lock. 10. A vehicle securing system in accordance with claim 1, wherein the at least one operating parameter is defined by an actuation of the brake pedal. 11. A vehicle securing system in accordance with claim 1, wherein the predetermined speed threshold value is zero km/h. 12. A vehicle securing system in accordance with claim 1, wherein the predetermined speed threshold value is about 3 km/h. 13. A vehicle securing system in accordance with claim 2, including an indicator for indicating to the driver the expiration of the subsequent operation period. 14. A vehicle securing system in accordance with claim 13, wherein the indicator is an acoustical indicator. 15. A vehicle securing system in accordance with claim 13, wherein the indicator is a visual indicator. 16. A vehicle securing system in accordance with claim 1, wherein the control device and the transmission are activated when the driver actuates the brake pedal after switching off the ignition. 17. A vehicle securing system in accordance with claim 16, wherein activation of the control device and the transmission occurs for the duration of an actuation of the brake pedal. 18. A vehicle securing system in accordance with claim 16, wherein activation of the control device and the transmission occurs for the duration of an actuation of the brake pedal and subsequently for an additional period of time. 19. A vehicle securing system in accordance with claim 18, including an indicator for indicating to the driver the end of the activation period. 20. A vehicle securing system in accordance with claim 19, wherein the indicator is an acoustical indicator. 21. A vehicle securing system in accordance with claim 19, wherein the indicator is a visual indicator. 22. A vehicle securing system in accordance with claim 1, wherein the control device includes a sensing means for sensing the position of the selector lever. 23. A method for preventing vehicle rolling after ignition shutoff for a vehicle having an automated transmission that has programmed controls and actuators for shifting the transmission into a gear selected by a vehicle driver by the driver's operation of a selector lever after ignition shutoff, and having a clutch for selectively interengaging the transmission with an engine, said method comprising the steps of: activating a control device for receiving and processing a plurality of motor vehicle operating parameters and for engaging a selected gear stage within the transmission; sensing vehicle speed; and shifting the transmission into the gear selected by the driver when the vehicle speed is below a predetermined threshold value. 24. A method in accordance with claim 23, wherein the activation step is functional for a predetermined time interval after ignition shutoff. 25. A method in accordance with claim 24, wherein the predetermined time interval is about 10 seconds. 26. A method in accordance with claim 23, wherein the activation step is initiated by driver actuation of a vehicle brake pedal.
