  • Publication number: 20200224567
    Abstract: The invention relates to a process, consisting in cooling at least one component, such as a sensor, arranged within a compartment of an exhaust after treatment system of a vehicle. The exhaust after treatment system comprises a cooling system that is activated during active regeneration of one or more particulate filters arranged within the exhaust after treatment system compartment and that includes a pipe, for blowing fresh air on the component to be cooled or for extracting hot air present at the vicinity of the component to be cooled, so that said component is protected as a priority against high temperatures during active regeneration periods.

  • Patent number: 10344827
    Abstract: A dual clutch transmission includes a first and a second input shaft provided with a first and second input arrangement, respectively, a center shaft, a countershaft, and a first and a second primary gear step. The first and second input shaft are coaxially arranged with the center shaft and can transfer torque from the first and second input means to the countershaft via the first and the second primary gear step. The first primary gear step including a first input gearwheel and a first driven gearwheel. The first input gearwheel is rotationally fixed with the first input shaft. The first input gearwheel is arranged upon the center shaft.

  • Patent number: 10330029
    Abstract: A method for a more efficient use of a vehicle combustion engine during driving, the vehicle including an automatic step geared transmission. The method includes the steps of sensing current engine rotational speed and engine rotational speed increase, estimating necessary minimum upshift engine rotational speed for a coming gear upshift, registering that the engine rotational speed stops increasing without reaching the minimum upshift engine rotational speed, and where the engine rotational speed stops increasing relatively close to a maximum engine rotational speed where engine efficiency is relatively low and, automatically controlling engine output torque in order to limit the engine rotational speed to a first predetermined engine speed where engine efficiency is relatively high.

  • Patent number: 10315522
    Abstract: A charge/discharge system includes a controller to control an electric power converter placed between a capacitor and a secondary battery connected in parallel. The controller includes: a request power calculation unit configured to calculate request input/output power for the electric motor generator based on current and voltage of the capacitor and input output current of the electric power converter; a capacitor discharging bias factor map configured to specify a ratio of electric power to be supplied from the capacitor to the electric motor generator to the request input power of the electric motor generator; a capacitor charging bias factor map configured to specify a ratio of electric power to be stored in the capacitor from the electric motor generator to the request output power of the electric motor generator; and a subtraction unit configured to calculate charge/discharge power of the secondary battery by subtracting, from the request input/output power, the charge/discharge power of the capacitor.

  • Patent number: 10253670
    Abstract: An exhaust gas-treating device (1) for an exhaust system of an internal combustion engine, especially of a motor vehicle, has a housing (2), which has a jacket (3) extending circumferentially on the side and two end-side end bottoms (4, 5). Maintenance is simplified with at least one mounting tube (6), which passes through one or the first end bottom (4) and into the outlet end (8) of which a particle filter (7) is plugged axially from the outside, with a deflecting housing (9). The deflecting housing (9) contains a deflecting chamber (10), and has at least one inlet (11) communicating with the deflecting chamber (10) and at least one outlet (12) communicating with the deflecting chamber (10). A fastening device (13) is provided for detachably fastening the respective inlet (11) at the respective outlet end (8) of the mounting tube (6).
