Process for Automatically Turning Off and Starting an Internal-Combustion Engine
First Claim
1. A process for automatically turning-off and starting an internal-combustion engine in a motor vehicle having a start-stop device that automatically turns off the internal-combustion engine when the vehicle is braked to a stop and held in a stopped position by operation of a brake pedal and automatically turns on the internal-combustion engine upon release of the operated brake pedal, the process comprising the acts of:
- automatically turning off the internal-combustion engine when the vehicle is braked to a stop and held in the stopped position by operation of the brake pedal; and
preventing the automatic starting of the internal-combustion engine based upon the release of the operated brake pedal if the operated brake pedal is increasingly depressed beforehand while the internal-combustion engine is off.

Abstract
A process and a corresponding system are provided for automatically turning off and starting an internal-combustion engine in a motor vehicle via a start-stop device, which automatically turns off the internal-combustion engine if the vehicle is braked to a stop and is held in the stopped position by the operation of the brake pedal, and which, if the internal-combustion engine is automatically turned off and the operated brake pedal is released, automatically starts the internal-combustion engine. If the internal-combustion engine is automatically turned off, an automatic starting of the internal-combustion engine by releasing the brake is prevented if the brake pedal was increasingly depressed beforehand while the internal-combustion engine was turned-off.

14. A start-stop system for a motor vehicle having an internal-combustion engine and a brake pedal, the system comprising:
a control unit of the start-stop system, the control unit including a memory having programmed therein code segments that; automatically turn off the internal-combustion engine when the vehicle is braked to a stop and held in the stopped position by operation of the brake pedal; and prevent the automatic starting of the internal-combustion engine based upon release of the operated brake pedal if the operated brake pedal is increasingly depressed beforehand while the internal-combustion engine was turned-off.
