Claim 8:
9. A method for measuring one or more parameters of resistive sensors in a motor vehicle, said method being implemented by a device as claimed in claim 1 installed in said vehicle and said method comprising:
connecting the center tap of the second measuring branch to the voltage supply,
measuring the value of the voltage defined between the center tap of the first measuring branch and ground,
connecting the center tap of the second measuring branch to ground,
measuring the value of the voltage defined between the center tap of the first measuring branch and ground,
calculating the resistance value of the first resistive sensor and the resistance value of the fourth resistive sensor from the voltage value measured between the center tap of the first measuring branch and ground when the center tap of the second measuring branch is connected to the voltage supply, the voltage value measured between the center tap of the first measuring branch and ground when the center tap of the second measuring branch is connected to ground, the value of the supply voltage and the predetermined value of the reference resistor,
