US 8,710,949 B2 · Remote ignition system for a vehicle and method for securing a remote ignition function

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.
