摘要:
The invention relates to a method of controlling a motor vehicle internal combustion engine comprising a step for evaluating whether the torque setting (1) is less than a threshold torque (Ts) different from the minimum torque which can be achieved with the current number of active cylinders (3) and different from the maximum torque which can be reached with one active cylinder (5) less.
摘要:
The invention relates to a method for estimating the ageing of a catalyst located in the exhaust line of a motor vehicle, in which a vehicle operating parameter (km vehicle) serves as a parameter for evaluating the ageing of the catalyst, characterised in that the evaluation parameter is adjusted taking account of at least one parameter (Mes OSC) specific to the catalyst, thereby determining a unique re-adjusted evaluation parameter (km adjust) for monitoring the ageing of the catalyst.

The invention relates to an electromagnetic actuator (17) for a valve (9) of an internal combustion engine, comprising: a frame (19) defining a magnetic circuit including a magnet (22) and an external polar piece (23a, 23b) defining a primary bore (29); and a primary moving part (20) including a valve (9). The electromagnetic actuator (17) also comprises: a secondary bore (30) close to the primary bore (29); and a secondary moving part (21) including a valve (9).
摘要:
Method for adjusting the ignition advance, controlled by a computer (10), of an internal combustion engine (2) comprising at least one cylinder (3), this method involving the operations consisting, in the case of the computer (10), in: • - recording a number of cycles performed in the cylinder and the value of an ignition advance curative correction for each cycle, and • - calculating an ignition advance adaptive correction during which the computer (10) averages the curative correction value as a function of the number of cycles elapsed and then calculates an adaptive correction value on the basis of this average, the triggering of the task of calculating the adaptive correction occurring when a predefined number of cycles has been reached. This number may be variable and dependent on the engine operating speed.

The invention relates to a device for controlling a hydraulic machine (1) of a power train and to a method for controlling the hydraulic machine (1). The invention also relates to a control device capable of assessing the increase in the masking noise generated by variation of the actual speed of the vehicle and determining a limit to the operating state of the hydraulic machine (1) on the basis of the actual speed of the vehicle. The invention is of use in a vehicle including a hydraulic machine.

The invention relates to a optical block (BO) which is suitable for being provided on a vehicle and comprises a lens (G), heating means (MC) producing heat energy intended for heating the lens (G), at least one source (SL) generating photons intended for participating in a photometric function, at least one lens (L) suitable for deflecting the generated photons so as to direct same towards the lens (G), and at least one mask (M) comprising a surface (FM) suitable for reflecting incident photons which are not directed towards the lens (G) and comprising at least one photovoltaic cell (CP) arranged so as to convert received incident photons into an electric current suitable for powering the heating means (MC).
摘要:
The invention relates to a system (3) for handling an engine block (4) arranged at the front of the body of a motor vehicle, said handling system (3) comprising a crossmember (5), a holding arm (11) mounted on the crossmember (5) and secured to the engine block (4), and at least two shoes (17) mounted on the crossmember (5) and positioned either side of the holding arm (11), the system comprising a pair of adapters (22, 23) mounted on the body of the motor vehicle, the shoes (17) being able to rest on said adapters (22, 23).
摘要:
The invention relates to a scooter-type vehicle (1) with caster wheels, comprising: a platform (2) having a rear wheel (4) mounted to the rear thereof, and a steering column (3), of which the upper longitudinal end (12) is connected to handlebars (13) and the lower end (15) is connected to a fork (9) carrying a front wheel (10), the platform (2) and the steering column (3) being connected by a connecting body (7). The vehicle is characterised in that the connecting body comprises a stem (8) to which the nose of the fork (9) is attached by means of a rotation shaft, and the steering column is pivotably mounted on the fork so that it can be folded towards the platform (2).
摘要:
The invention concerns a floor (8) of a motor vehicle (2) comprising: a central tunnel (10); at least one sill (12) extending along and at a distance from the central tunnel (12); a wall (14) extending transversely from the central tunnel (10) to the sill (12); and one or more profiled sections (16) extending transversely on the wall (14) between the tunnel (10) and the sill (12); the or at least one of the profiled sections (16) comprises a profiled wall (18) extending along the length (24) of the profiled section (16), said wall (18) comprising, at the end of same on the sill side, a portion (20) with means (22) promoting the compressive deformation of said profiled section (16) in case of a side impact. The invention also concerns a vehicle comprising such a floor (8).
