摘要： The diagnosis method of the invention implements a membrane pump to set an overpressure in the fuel vapor recovery system. According to the invention, after measuring a first time (TM1) for a membrane of the leak detection pump to pass from a high position (H) to a predetermined position (S), a predetermined pressure (P1) is maintained in the system while waiting for the drain valve to open. Then, a second time (TM2, TM'2) is measured for the membrane to pass from the high position (H) to the predetermined position (S) during the opening of the drain valve. The first and second times are compared and if the second time (TM2) is substantially lower than the first time (TM1), it can be ascertained that the drain valve is operating properly. The present invention relates more particularly to the motor vehicle industry.

摘要： A method for diagnosing a fuel vapour recovery system using a pump (10) with a membrane (11) particularly including means (12) for generating a signal indicating a predetermined position of the membrane, and a system venting valve (15) that is normally open when the pump is inoperative and closed when it is operative. According to the method, the operation of the valve is diagnosed by comparing a first time (TM1) taken by the membrane to return to the predetermined position after a first series of pumping cycles with a second time (TM2; TM2') taken by the membrane to return to the predetermined position after a second pumping cycle once the pump has been inoperative for a predetermined time (TA).

摘要： Samples are taken, in a time window surrounding the presence of a predetermined fault, of predetermined context variables, processing is applied to the acquired samples in order to derive from them a reduced form of these samples constituted by a set of ''moments'' associated with each of the context variables (for example the mean value and the variance), this set is stored and the stored set is updated at each of the successive manifestations of the intermittent fault. The sets of moments thus updated can be transmitted to a diagnostic tool (8) allowing the establishment, by correlations, of the origin of the functional fault. Application to a device installed in a motor vehicle for the detection of intermittent functional faults of units forming part of that vehicle.

摘要： A method for sensing excess pressure in a motor vehicle fuel vapour recovery system, wherein a leak sensing pump is activated for a predetermined time tp needed in a typical recovery system for the prevailing pressure in the tank to reach a so-called threshold pressure value (Ps) corresponding to a maximum allowable starting pressure (Ps0) at which a calibrated leak may be sensed in the typical recovery system; the time (TM) taken by a pump membrane to move from a raised position (H) to a predetermined position (S) is measured at the end of the pump activation time (tp); the measured time (TM) is compared with a threshold time (TMs) corresponding to the time taken by the membrane to move from the raised position (H) to the predetermined position (S) when the prevailing pressure in the typical system is the threshold pressure (Ps); and it is determined that a method for sensing leaks in the vapour recovery system may be implemented if the measured time (TM) is less than the threshold time (TMs). Said method may be used in the field of motor vehicles.
