Method and Start Control Device for Controlling an Automatic Start-up Process of a Drive Unit
First Claim
1. A method for controlling an automatic start-up process of a drive unit for a motor vehicle, the drive unit being automatically started when all predetermined start-up conditions are fulfilled, one of which is a requirement that an absence of a driver is not detectable, the method comprising the acts of:
- determining that said one start-up condition is not met;
determining whether a speed of the motor vehicle is greater than a predetermined limit speed; and
automatically starting the drive unit even when said one start-up condition is not met when the speed of the motor vehicle is greater than the predetermined limit speed and all other predetermined start-up conditions of the automatic start-up process of the drive unit are met.

8. A start control device for controlling an automatic start-up process of a switched-off drive unit of a motor vehicle, the start control device comprising:
-
one or more start-up condition detection units, an automatic start-up process being initiated when all defined start-up conditions are detected, at least one start-up condition being a requirement that an absence of the driver is not detectable; a motor vehicle speed determination unit that determines when a speed of the motor vehicle is greater than a predetermined limit speed; and wherein the start control device initiates the automatic start-up process even when the absence of the driver is detected by said one start-up condition if the speed of the motor vehicle is greater than the predetermined limit speed and all other defined start-up conditions are met.
