A remote ignition system for a vehicle witha remote ignition control device (20)for 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 (40) for detecting the intention of a driver to start driving; and
an engine control device (30), which comprises the following;
i. a first evaluation unit (32) for evaluating a signal which has been received from the remote ignition control device (20);
ii. a unit (33) coupled to the first evaluation unit (32) 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 (35) for evaluating signals which have been received from the means (40) for detecting the intention to start driving;
the engine control device (30) furthermore comprises a storage unit (37) for storing the last signal evaluated by the evaluation unit (32), and a test unit (36) which is coupled to the second evaluation unit (35), to the storage unit (37), and to the unit (33) for starting and stopping the engine and which is designed to read out the signal stored in the storage unit (37) when the second evaluation unit (35) has ascertained the intention to start driving and, if it is a release signal, to send a blocking signal to the unit (33) for starting and stopping the engine and to modify the contents of the storage unit (37).

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.
