  • Publication number: 20210253083
    Abstract: A method for evaluating an operating condition of a motor vehicle, which includes an electrical-mechanical energy converter and a chemical-mechanical energy converter, is provided. The method includes detecting an operating condition of the chemical-mechanical energy converter of the motor vehicle, transmitting the detected operating condition of the chemical-mechanical energy converter to a location remote from the motor vehicle, and evaluating the detected operating condition of the chemical-mechanical energy converter at the location remote from the motor vehicle by comparing the operating condition of the chemical-mechanical energy converter with a reference value of the operating condition of the chemical-mechanical energy converter in order to determine emissions of a motor vehicle fleet including at least two motor vehicles.

  • Patent number: 7448975
    Abstract: A transmission device (3) for a vehicle with an electric machine (26) that is arranged in a housing (11) is described. The electric machine (26) can be placed in active connection with a rotating component (13, 28) that can be guided in the power flow of the transmission device such that a level of torque that can be generated by the electric machine (26) can be transmitted to the component (13, 28). At least one electric component (45; 45Y) that comprises power electronics for the electric machine (26) is arranged in a cross-sectional area inside the housing (11) that is perpendicular to the longitudinal axis of the electric machine (26) and is located directly adjacent to the electric machine (26).

  • Patent number: 7445573
    Abstract: A transmission device (3) of a vehicle for distributing a driving torque of a transmission input shaft (13) to at least two transverse vehicle shafts (4; 4X; 4Y; 4Z; 5). Between the transmission input shaft (13) and a transmission output shaft (15) gear elements (16 to 25) are disposed in a housing (11) for the purpose of implementing different gear ratios. One of the vehicle axles (4; 4X; 4Y; 4Z) extends through an inner space (10) of the housing (11). In a cross-sectional area disposed perpendicular to the longitudinal axis of the transmission device (3), in which area the transverse vehicle shaft (4; 4X; 4Y; 4Z) that is guided through the housing (11) is disposed, at least part of an electrical device (45, 46), which is mounted to the housing side, and/or at least part of a temperature control unit (47), which is mounted to the housing side, are provided.

  • Patent number: 6155951
    Abstract: The invention relates to a transmission in which the input power is either directly transmitted by an input shaft (2) to an output shaft (17) or indirectly transmitted via a continuously variable transmission (5), in particular a transmission with toroidal races (6, 8 and 7, 9 respectively) which work together in pairs and between which rotate rolling bodies (10) and a planetary gear (18). According to the invention the first power range corresponds to a first forward travelling speed range in which the input power is transmitted via the variator (5) to the output shaft (17) and the planetary gear (18) revolves as a unit, and one other power range follows the first power range and corresponds to a range of higher forward travelling speeds in which the input power is divided and supplied to the planetary gear directly and via the variator (5) which totals and transmits it to the output shaft (17).
