  • Publication number: 20200207205
    Abstract: Disclosed is a solution to the use of a speed limiter in a motorcycle that has a high capacity for acceleration, including a method for limiting the speed of a motorcycle using precise parameters of speed, acceleration and required engine torque and a single control button to manage the smart activation and deactivation of the limiter and to input new speed limits Vlim in a simple way. It thus allows the use of a speed-limiting system in a motorcycle that has a high power/weight ratio by avoiding the sources of interference with the riding and the effects liable to jeopardize its stability.

  • Patent number: 10697386
    Abstract: A method for measuring the flow rate MAF of cool air entering an intake manifold of a two-stroke engine, the intake manifold being located between a throttle body and an intake system. The method uses a specific prediction model depending on whether the two-stroke engine is subject, on the one hand, to a light load and, on the other hand, to a medium or heavy load. The model suitable for the load is selected using a predetermined threshold and two absolute pressure measurements taken at the intake manifold at crankshaft angles of rotation around top dead center and bottom dead center. Next, a pressure quotient is formed for each model which will be used to deduce the flow rate of cool air entering the intake manifold.

  • Patent number: 10471566
    Abstract: Disclosed is a method for determining location of a lens machining tool (24) having an offset location according to a first direction (Y) smaller than a first predetermined threshold, including the steps of manufacturing a calibration piece (10) according to a predetermined theoretical geometry by using the lens machining tool for providing a at least partially annular groove in a main surface of the calibration piece, the at least partially annular groove being configured to form at least one sharp edge defining a slope discontinuity on the main surface; measuring a distance between the at least one sharp edge and a turning center of the calibration piece for providing data of geometrical characteristics of the calibration piece; and deducing from the measured data a location of the lens machining tool according to a second direction (X) distinct from the first direction.

  • Patent number: 6389363
    Abstract: Process for calculating the torque of an internal combustion engine having electronic injection. The method includes having a cogged target with an indexed reference rotating before a fixed sensor. The defects of the target are corrected by distinguishing the combustion interval of the target from the reference. A term assigned to each interval is $g(b)i which is determined in the absence of combustion from the measurement of the engine torque which is proportional to the pressure in the commutator represented by the equation Ci=K.Pcoll=&agr;(&Sgr;N+$g(b)i)N2 where Ci is the engine torque, Pcoll is the pressure, N is the engine power, K is the proportionality factor and &agr; is a constant term.

  • Patent number: 6334357
    Abstract: A method for detecting a misfire in at least one truck or motor vehicle internal combustion engine cylinder by analysing the values (Cg, n, i) of a quantity (Cg) characteristic of combustion and generated by observing the rotation of the crankshaft to detect the occurrence of a misfire. According to the method, misfire detection is suspended for a predetermined time when the analysis of said values (Cg, n, i) reveals anomalies originating in the transmission power line between the drive shaft and the vehicle wheels.
