  • Method for securing the operation of a voltage-holding device for a vehicle
    Patent number: 9091243
    Abstract: The invention relates to a method for securing the operation of a voltage-holding device used for starting or restarting the internal combustion engine of a vehicle, the voltage-holding device being electrically connected by a multiplex network to an electric machine and to a monitoring computer. According to the method, the voltage-holding device can be activated only if it has previously received an activation authorization message, which can be a starting or restarting message, sent by the computer to the electric machine and to the voltage holding device, or a message transmitted by the electric machine indicating that it is about to restart the internal combustion engine.

  • METHOD FOR SECURING THE OPERATION OF A VOLTAGE-HOLDING DEVICE FOR A VEHICLE
    Publication number: 20110298277
    Abstract: The invention relates to a method for securing the operation of a voltage-holding device (DMT) used for starting or restarting the heat engine of a vehicle, said device being electrically connected by a multiplex network (12) to an electric machine (10) and to a monitoring computer (4). According to the invention, the DMT can be activated only if it has previously received an activation authorisation message (16, 18), which can be a starting or restarting (16) message, sent by said computer (14) to said electric machine (10) and to said voltage holding device (DMT), or a message (18) transmitted by said electric machine (10) indicating it is about to restart the heat engine.
