SAFE START-UP INTERFACE FOR A VEHICLE WITH AN ELECTRIC STARTER
First Claim
1. Safe start-up method for a vehicle provided with an electric starter whereof the battery is at least partially run down, or having difficulties starting up, this method making use of an interface comprising at least two pairs of input/output terminals each of which can be connected indifferently to said run down battery or to another electrical energy source and independently of polarity, this interface comprising means for measuring the voltage T1 and T2 and polarity of the terminals of each of the pairs as well as connection means comprising a general switch, these connection means connecting the two pairs of terminals so as to provide, according to the polarities detected, a connection between the terminals of identical polarity, said method comprising:
- a) connecting either of the two input/output terminal pairs, to said run down battery and the other two input/output terminal pairs to said energy source, and independently of polarity, the connection means being open,b) detecting the voltage T1 and T2 and the polarity at the terminals of each of the pairs and comparing the voltages T1 and T2 with a predetermined threshold value TS,c) establishing a connection between the terminals of the two pairs of terminals using said connection means such that the terminals of the same polarity can be connected to each other by conductive links at least one of which is controlled by said general switch,d) closing of said general switch being done only in the case where the two values of the two detected voltages T1 and T2 are above said threshold TS,e) limiting the intensity I to a predetermined maximum value Imax,f) starting the motor with the help of a start-up control of the starter.

Abstract
The invention relates to method of safely starting a vehicle, comprising the following steps, consisting in: connecting either of the two input/output terminal pairs (ES1, ES2) or (ES3, ES4) to the run down battery (5) and the other input/output terminal pair (ES1, ES2) or (ES3, ES4) to the power source (2) independently of polarity, the connection means being open; detecting the voltage and polarity at the terminals of each of the pairs and comparing the voltages at the terminals (ES1, ES2) and (ES3, ES4) with a pre-determined threshold value; and configuring the links of the connecting means between the terminals of the two terminal pairs such that terminals of the same polarity can be connected to one another using conductive links, at least one of which is controlled by a general switch (8).

5. Safe interface for start-up of a motor vehicle provided with an electric starter whereof the battery is at least partially run down, or having difficulties starting up, this interface comprising at least two pairs of input/output terminals, said safe interface comprising:
-
at least one connection means allowing each pair of input/output terminals to be, completely safely, connected indifferently to said run down battery or to another electric energy source and independently of polarity, at least one means for measuring the voltage and polarity of the terminals of each of the pairs, at least one limiting means maintaining the value of the intensity I below a predetermined threshold Imax, at least one commutation means between the two pairs of terminals which, according to the polarities detected, only provides a connection between the terminals of identical polarity if the values of said measured voltages T1 and T2 are greater than a predetermined threshold Tmin. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
