Abstract: The invention relates to an electrical system comprising: —terminals (V+, V?) capable of being connected to an installed electrical power source (4) capable of delivering an electrical voltage between said terminals; —a circuit for detecting an electrical insulation fault between the electrical power source and a housing (14) forming a floating electrical ground. The detection circuit comprises: •a controllable voltage generator (40) capable of polarizing the housing and the single first terminal at different potentials; •a current measurement device (44) measuring current entering on said first terminal and leaving at a point of the source; •a control unit (46) capable of calculating a value of at least one insulation resistance from said at least one measured current value.

Abstract: An electrical power supply system includes a battery of cells, the battery including an ammeter configured to measure battery current flowing through the battery, and at least one voltage sensor configured to measure voltage at terminals of a cell. An electronic control unit is configured to deliver a maximum permissible electrical power setpoint. The control unit is configured to calculate a maximum permissible electrical power associated with a cell by taking the minimum of at least two values, including a first electrical power and a second electrical power.

Abstract: The invention relates to a system for managing the charging of at least one cell of a storage battery, comprising: two separate means for comparing the voltage across the terminals of said cell with a threshold voltage; and two separate controlling means adapted to control two actuators, respectively, in order to interrupt the charging of the storage battery when said first or second comparing means detects that the voltage across the terminals of said cell exceeds the threshold voltage. One of the actuators is formed by a charger that is connected to said storage battery in order to recharge said cells.

Abstract: A method for hill start assistance for a motor vehicle and to an associated device that includes a clutch and a transmission between the clutch and driving wheels of the vehicle. The method determines the torque of the clutch for maintaining the vehicle in an immobile position based on a known engine torque, wherein the torque of the clutch is determined by taking into account a portion of the engine torque dedicated to operation of constituent mechanisms of the vehicle other than the clutch.

Abstract: A method for controlling orientation of rear wheels of a vehicle, by a computerized control system, including a module for calculation of a deflection angle for the rear wheels as a function of a deflection angle of the front wheels. In the method, when the front wheels are oriented for a period of time such that the vehicle follows a curved trajectory with an inner side and an outer side, the rear deflection angle, as determined by the calculation module, is corrected and limited to a maximum value calculated instantaneously such that a rear corner then follows a trajectory remaining within the curved trajectory previously followed by a front corner and, furthermore, at a tangent to the same.
