Device for influencing the starting of the internal combustion engine of a motor vehicle with electronically controlled gearbox
First Claim
1. Device for influencing starting of an internal combustion engine of a motor vehicle that has an electronically controlled gearbox, an electrically acting interlock that prevents the internal combustion engine from being put into operation when a gearbox status causing a driving force connection is selected, a starter with an electromagnetic disengagement switch that is supplied with battery current from an ignition switch during actuation of the starter, the device comprising:
- an electronic engine control unit for at least one of ignition and metering of fuel, with a communicative connection communicatively connecting the engine control unit to the gearbox control;
a direct connection from the ignition switch to the electromagnetic disengagement switch for supplying battery current to the electromagnetic disengagement switch without an intermediate disabling switch;
a recorder that records a position of an element influencing the gear-selection status of the gearbox and transmits a corresponding signal to the gearbox control;
wherein the gearbox control acts upon the engine control unit via the communicative connection to disable at least one of the ignition and the fuel metering when the element influencing the gear-selection status of the gearbox is in a position which normally effects a driving force connection through the gearbox.

Abstract
A device is provided for influencing starting of an internal combustion engine of a motor vehicle that has an electronically controlled gearbox, an electrically acting interlock that prevents the internal combustion engine from being put into operation when a gearbox status causing a driving force connection is selected, and a starter with an electromagnetic disengagement switch that is suppliable with battery current from an ignition switch during actuation of the starter. The device has an electronic engine control unit for at least one of ignition and metering of fuel, with a communicative connection communicatively connecting the engine control unit to the gearbox control. A direct connection is provided from the ignition switch to the electromagnetic disengagement switch for supplying battery current to the electromagnetic disengagement switch without an intermediate disabling switch. A recorder records the position of an element influencing the gear-selection status of the gearbox and transmits a corresponding signal to the gearbox control. The gearbox control acts upon the engine control unit via the communicative connection to disable at least one of the ignition and the fuel metering when the element influencing the gear-selection status of the gearbox is in a position which normally effects a driving force connection through the gearbox.
