System for indicating the level of fuel contained in the tank of a motor vehicle

摘要

The system comprises a control unit which, when the engine is stopped, memorises the level indicated by a display device upon stopping and then the level indicated by a sensor a predetermined time after stopping. The unit then memorises the level indicated by the sensor a predetermined time after the subsequent restarting of the engine. The unit controls the display device in a predetermined manner depending on the relative values of the memorised levels.
