Abstract: A method for controlling electric power supply of a motor vehicle including a power unit and an electric power supply battery, the vehicle including at least one autonomous computer, at least one master computer, and at least one slave computer, the computers connected by a data network, the autonomous computers each configured to carry out at least one task after the power unit has stopped, and the power supply to the computers being maintained for a first period of time. The control method includes: reporting absence of the autonomous computer to the master computer; interrupting the power supply of each slave computer; interrupting the power supply of the master computer; maintaining the power supply of the autonomous computer beyond the first period of time; interrupting the power supply of each autonomous computer once it has finished its task.

Abstract: A method for controlling an automatic gearbox pertaining to a motor vehicle in a braking phase. According to the method, a gear ratio or speed value of the gearbox, requested on the basis of pre-established laws, is determined; and, on the basis of the value and parameters representative of the situation of the vehicle, a corrected gear ratio or speed value of the gearbox, able to trigger an anticipated downshifting of the automatic gearbox, is determined. The corrected gear ratio value of the gearbox is determined on the basis of an estimation of the desired primary speed for the automatic gearbox.

Abstract: The inventive method for controlling the gear change of an automatic gearbox provided with distinct shifting rules or variograms used according to a vehicle operating conditions consists in detecting and carrying out gear shifting requests sequential to the shifting rule or variogram switching, subject to the application of specific conditions only.
