摘要： Disclosed is a method for controlling the pressure inside a fuel tank of a motor vehicle, the motor vehicle including a fuel vapor vent circuit connecting the tank to a fuel vapor canister, the vent circuit including an isolation valve for isolating the tank and a rollover valve. The pressure control method includes steps of: determining an activation duration required for the isolation valve to transition from a closed state to a fully open state, referred to as the “full opening duration”, when a predefined rollover valve closure risk criterion is satisfied: controlling the isolation valve in repeated activations of respective durations that are shorter than the full opening duration.

摘要： Disclosed is a device for evaporating vapors of a fuel stored in a motor vehicle tank. The evaporation device includes a bypass circuit and a bypass valve configured to move between a so-called “absorption” position, in which the bypass valve allows the gases to flow between the tank and an absorbent filter and a so-called “leak detection” position, in which the bypass valve allows the gases to flow between a purge circuit and the tank via the bypass circuit.

摘要： Disclosed is a method for controlling depressurization in a fuel tank of a motor vehicle, including: the initial controlled opening of the isolation valve in order to lower the pressure inside the tank; determination of a blockage condition in the roll over valve on the basis of at least one item of information relating to the pressure gradient in the tank following the initial opening of the isolation valve; and, if the roll over valve blockage condition is met, the controlled closing of the isolation valve, followed by its controlled re-opening in order to continue lowering the pressure in the tank.

摘要： Disclosed is a method for monitoring pressure, for a vessel assembly including a sealed vessel capable of holding a liquid, a filter capable of capturing vapors from the liquid, a pipe connecting the vessel to the filter, and an isolation valve arranged to selectively shut off the pipe, including a detection of the boiling of the liquid contained in the vessel.

摘要： An actuator/sensor device (1) includes: at least one actuator (3) controlled by a control signal and at least one sensor (5) transmitting an acquisition signal, the actuator (3) and the sensor (5) being integrated into the same component; an actuator/sensor pin (8) connecting a terminal of the actuator (3) and an output of the sensor (5) to the same single electrical wire (9) external to the actuator/sensor device (1); and switching elements adapted to cause either the control signal in a control phase (19) or the sensor information in an acquisition phase (21) to be sent on the electrical wire (9).

摘要： A method for detecting defective gas flow in a vent line of a device for purging a fuel vapor absorption filter of a vehicle's internal combustion engine during filling the vehicle's tank with fuel from a filler nozzle having a venturi effect duct, so as to stop the filling when the duct is full of fuel. The vent line connecting the fuel tank to the filter. The tank having: a filler pipe, at the end of which is a stopper designed so that, during filling with fuel from the filling nozzle, fuel vapors are evacuated through the vent line. At least one gauge measures fuel volume in the tank. The detection method continuously measuring the volume of fuel in the tank during filling and comparing a volume profile thus measured with respect to time against a predetermined volume profile. A defective flow detected if the two profiles do not match.

摘要： A method for checking a measurement of pressure in a fuel tank, implemented in a vehicle having a fuel tank and a fuel vapor breather circuit including: a filter, a tank isolation valve interposed between the tank and the filter, and a purge line, connected to the filter, downstream thereof, a pressure sensor, and a purge valve. The method includes, when the purge valve is closed: measuring a value of the pressure in the tank when the isolation valve is closed, then measuring a temporal extreme value for the pressure in the purge line following an opening of the isolation valve, and determining, from the measured values, that there is an anomaly in the measured pressure in the tank.

摘要： Disclosed are a method and device for determining a model of flowrate for a valve, including: instantiation of the model initially equal to an approximate model; choosing flowrate setting; determination of an initial command corresponding to the flowrate setting by the model; application of the initial command to the valve; observation of a discrepancy indicative of a difference between the flowrate setting and a flowrate achieved; if the discrepancy is not zero, application of a correction to the initial command, and return to the application step; if the discrepancy is zero, correction of the model by replacing, for the flowrate setting, the initial command by the corrected command, where the flowrate passing through the valve ends up in a combustion engine admission collector including a small-area controller regulating the flowrate of air admitted, and where the discrepancy of the observation step is the deviation of the small-area controller.
