Method and device for controlling cut-off of a motor vehicle starter
First Claim
1. A method of controlling cut-off of a motor vehicle starter during a starting operation of the vehicle, comprising the steps of providing a power supply having an output voltage to the starter variable with external conditions, measuring the output voltage of the power supply to the starter and interrupting power to stop the starter when the output voltage reaches a threshold value, the threshold value being a function of the value of said variable output voltage prior to the starting operation.

Abstract
A motor vehicle starter is controlled by a control device which cuts off the starter by measuring the power supply voltage of the starter and interrupting the power supply when that voltage reaches a threshold value. The threshold value is a function of the value of the power supply voltage measured at the inception of the starting operation.

- 4. A device for controlling cut-off of a motor vehicle starter, comprising a power supply for the starter variable with external conditions, a means for measuring the output voltage of the power supply to the starter, and a comparator connected to said measuring means for comparing the measured voltage with a predetermined threshold voltage, a means for memorizing the measured power supply voltage prior to the starting operation, the said threshold value being a function of said variable power supply voltage prior to the starting operation and a means for interrupting the power supply to the starter when the output voltage reaches the threshold voltage.
