  • Patent number: 9517763
    Abstract: A transmission control system for a hybrid-power driving system includes at least a gear shifting actuation module to control engagement of specific gearwheels and a clutch actuation module to control a clutch that couples an engine to the transmission. Gear shifts are required for each of the engine and the electric motor in the hybrid-power driving system. By selectively controlling the clutch and engagement of specific gearwheels, the transmission control system can start the engine when the vehicle is initially powered by the electric motor alone. Starting the internal combustion engine in this case switches the vehicle from a pure motor driving mode to a hybrid driving mode. Additionally, the transmission control system can start the engine when the vehicle is in a parked state, for example, to put the vehicle in a battery charging mode for the electric motor.

    Abstract: A power transmission control device, which is applied to a hybrid-vehicle provided with an internal combustion engine (E/G) and a motor (M/G) as power sources, includes a manual transmission and a friction clutch. When the shift position is in “neutral”, the friction clutch is in an engaged state, an accelerator opening is “0”, and a battery remaining amount SOC is less than a threshold TH, a charge condition is satisfied. When the charge condition is satisfied, charge of a battery by using an E/G torque is carried out. Specifically, the M/G is driven, by using the E/G torque, as an electrical power generator, and electric energy acquired by electric power generation by the M/G is used to charge the battery. As a result, for the HV-MT vehicle, by using the internal-combustion-engine torque, the battery for supplying the electric motor with the electric energy can be efficiently charged.

    Abstract: A device includes a transmission and an electric machine for a hybrid drive of a motor vehicle, and the transmission includes first and second subtransmissions. The substransmissions each have an input shaft and they share an output shaft. The input shafts of the subtransmissions can be selectively coupled to the output shaft via form locking clutches of the subtransmissions. In particular, a first input shaft of the first subtransmission is allocated to a first friction locking clutch while a second input shaft of a second subtransmission is allocated to a second friction locking clutch. Furthermore, a third clutch is incorporated between an input drive side clutch half of the first friction locking clutch and an input drive side clutch half of the second friction locking clutch.

  • Patent number: 8862344
    Abstract: A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.
