Remote ignition system for a vehicle and method for securing a remote ignition function
First Claim
1. A remote ignition system for a vehicle witha remote ignition control devicefor receiving a signal for activating a remote ignition,for checking of at least one remote ignition prerequisite which comprises the locking of the doors,for locking the doors when the signal for activating a remote ignition has been received and the doors are not locked, andfor providing a release signal when the doors are locked;
- means for detecting the intention of a driver to start driving; and
an engine control device, which comprises the following;
i. a first evaluation unit for evaluating a signal which has been received from the remote ignition control device;
ii. a unit coupled to the first evaluation unit for starting the engine in response to a release signal and for stopping the engine in response to a blocking signal; and
iii. a second evaluation unit for evaluating signals which have been received from the means for detecting the intention to start driving;
the engine control device furthermore comprises a storage unit for storing the last signal evaluated by the first evaluation unit, and a test unit which is coupled to the second evaluation unit, to the storage unit, and to the unit for starting and stopping the engine and which is designed to read out the signal stored in the storage unit when the second evaluation unit has ascertained the intention to start driving and, upon a release signal from the storage unit, to send a blocking signal to the unit for starting and stopping the engine and to modify the contents of the storage unit.

Abstract
The invention relates to a remote ignition system for a vehicle with a remote ignition control device for activating a remote ignition by providing a release signal, means for detecting a driver'"'"'s intention to start driving, and an engine control device which comprises the following: a first evaluation unit for evaluating a signal which has been received from the remote ignition control device, a unit coupled to the first evaluation unit for starting of the engine in response to a release signal and for stopping the engine in response to a blocking signal, and a second evaluation unit for evaluating signals which have been received from the means for detecting the intention to start driving. The engine control device furthermore comprises a storage unit for storing the last signal evaluated by the first evaluation unit, and a test unit which is coupled to the second evaluation unit, to the storage unit, and to the unit for starting and stopping the engine and which is designed to read out the signal stored in the storage unit when the second evaluation unit has ascertained the intention to start driving and, if it is a release signal, to send a blocking signal to the unit for starting and stopping the engine and to modify the contents of the storage unit. The invention furthermore relates to a method for securing a remote ignition function.

11. A method for securing a remote ignition function, characterized by the following steps:
-
receiving a signal by a remote ignition control device for activating a remote ignition; checking of at least one remote ignition prerequisite by the remote ignition control device, where one of the at least one remote ignition prerequisites involves locking of the doors; locking of the doors by a signal of the remote ignition control device when the signal for activating the remote ignition has been received and the doors are not locked; providing a release signal by the remote ignition control device for activating a remote ignition when the doors are locked; receiving the release signal from the remote ignition control device by an engine control device; starting of an engine in response to the received release signal by the engine control device; detecting a driver'"'"'s intention to start driving and providing a driver'"'"'s intention signal; receiving the driver'"'"'s intention signal by the engine control device; evaluating the driver'"'"'s intention signal by the engine control device; shutting off the engine by the engine control device as soon as a driver'"'"'s intention to start driving is ascertained after a remote ignition. - View Dependent Claims (12, 13, 14, 15)

16. A system for the remote ignition of a motor vehicle comprising:
-
means for detecting a remotely transmitted signal for initiating the ignition of an engine of said vehicle; means for detecting at least one condition of said vehicle unsuitable to the remote ignition of said engine; means for effecting the suitability of said condition; means responsive to said signal and the suitability of said condition for igniting said engine; and means responsive to an initiation of said engine prior to ignition by said signal for precluding ignition of said engines by said remote signal, wherein said unsuitable condition comprises one of an unlocking of said vehicle, an opening of a vehicle door and the presents of an individual in said vehicle, and wherein said means for effecting the suitability of said condition comprises one of means for activating a door lock cylinder and means for activating a central locking system. - View Dependent Claims (17, 18)
