20120271535 | METHOD FOR MANAGING THE AUTOMATIC STOPPAGE OF AN AUTOMOBILE - A method including: a) determining a value representative of temperature of exhaust gases flowing in an exhaust duct of an engine upstream from a turbine; b) comparing the representative value with a predetermined threshold value; c) if the representative value is higher than the threshold value, initiating timing-out of a first time delay during which a) and b) are repeated; d) if the representative value is lower than the threshold value, initiating the timing-out of a second time delay during which a) and b) are repeated; e) if the first time delay has elapsed and the representative value is higher than the threshold value, preventing the automatic stoppage of the engine; f) if the second time delay has elapsed and the representative value is lower than the threshold value, authorizing the automatic stoppage of the engine and resetting the measure of the timing-out of the first time delay. | 10-25-2012 |
20120133179 | VEHICLE COMPRISING A PANE BONDED TO THE BODYWORK - A vehicle including at least one glass pane, bodywork, and at least one layer of viscoelastic material interposed between the glass pane and the bodywork. | 05-31-2012 |
20120104801 | METHOD FOR MOUNTING A TRANSVERSE UNDERSTRUCTURE MEMBER AND A TECHNICAL FRONT PANEL - A method for mounting on a motor vehicle at least one transverse understructure member and a technical front panel to be mounted at a longitudinal end of a frame structural member including two transversely opposite rails and two transversely opposite portions of the frame structural member, in particular hinging members for holding the vehicle headlights. The method includes placing the technical front panel in a vertical position on the transversely opposite portions of the frame structural member, and transversely positioning the technical front panel on the portions. | 05-03-2012 |
20110163654 | OPEN-CHAMBER MULTI-SPARK PLUG - An internal combustion engine radio frequency spark plug including two plasma-generating electrodes, separated by an insulator, that constitute respectively an outer shell enclosing the insulator and a central electrode housed in a central bore of the insulator. The spark plug includes a deep opening over the entire circumference of the shell, forming a heat-exchanger chamber inside the spark plug shell, opening outwards. | 07-07-2011 |
20100139252 | METHOD AND DEVICE FOR PURGING AN INJECTOR IN A FUEL INJECTOR SYSTEM OF USE IN THE REGENERATION OF A PARTICULATE FILTER - A method and a device for purging an injector in a fuel injector system of use in regeneration of a particle filter. The aging of fuel is determined and compared with a fuel aging threshold value, and a purge request is activated if the threshold value is exceeded. On activating the purge request the satisfaction of the conditions of purge activation are verified and, if satisfied, the purge is activated. The purge is continued while the conditions are satisfied until the quantity of fuel purged reaches a quantity of fuel to be purged. | 06-10-2010 |
20100087998 | METHOD AND DEVICE FOR VEHICLE DRIVING ASSISTANCE - A method and device for driving assistance for a propulsion unit of a vehicle with manual control of the transmission gear ratio, using a control system with a calculator controlling an indication to a driver of a recommended gear ratio based on a request information from the driver and depending on driving conditions of the vehicle at any moment, and a mapping of the gear change rules from which the ratio to be recommended is determined, depending on the vehicle speed at each moment, for an optimal fuel consumption and a minimized pollutant emission. The recommended ratio for an optimal consumption is corrected in successive steps by taking into account, one after the other, a set of constraints concerning the driving safety and comfort, each step having priority over the previous one so that the ratio finally recommended is an optimal balance between the different constraints while putting an emphasis on driving safety. | 04-08-2010 |
20090326785 | METHOD AND SYSTEM FOR CONTROLLING A LOW-VOLTAGE-POWERED PLUG FOR PREHEATING A DIESEL ENGINE AIR/FUEL MIXTURE - The invention relates to a method for controlling a low-voltage-powered plug ( | 12-31-2009 |
