  • Publication number: 20150051799
    Abstract: A method for synchronizing a gear on a parallel-shafts vehicle gearbox shaft including at least one primary shaft connected to a power source, one secondary shaft driven by the primary shaft to transmit driving torque to wheels over plural transmission ratios, and at least one mechanism coupling a gear to its shaft to engage a transmission ratio without mechanical synchromesh members. The power source is made to operate to produce a signal commanding the reference torque (T1ref), equal to minimum torque that can be transmitted to minimize a discrepancy (?2K ??1) between a primary speed (?1) and a secondary speed (?2) multiplied by a reduction ratio (K), when the relevant gear is coupled to its shaft, wherein the control signal is given by the sum (KwK?2?Ks?1+T1int), in which (T1int) is a term derived by integrating the primary speed (?1).

  • Publication number: 20150047915
    Abstract: Provided is a hybrid vehicle drive control device that achieves appropriate limp-home driving in the event of a clutch failure. The drive control device is equipped with: a clutch (CL) that connects/disconnects the carrier (C1) of a first planetary gear train (14) and the carrier (C2) of a second planetary gear train (16); and a brake (BK) that connects/disconnects said carrier (C2) to/from a housing (26). In the event of a failure in which the clutch (CL) is released in the absence of a control command, limp-home driving is performed while the brake (BK) is engaged. Consequently, appropriate limp-home driving can be enabled by minimizing unnecessary consumption of energy by a first electric motor (MG1) and a second electric motor (MG2).

  • Publication number: 20150032318
    Abstract: A vehicle having at least an electric traction motor and a passenger cabin includes a controller. The controller has a memory storing an expected range routine and a processor coupled to the memory. The processor is configured to execute the expected range routine. An expected range for the vehicle is determined referencing an average power consumption of a cabin conditioning system over an selected duration of initial cabin conditioning. During the selected duration of initial cabin conditioning, the average power consumption of the cabin conditioning system is added to an instantaneous power consumption of at least the electric traction motor to determine a total power consumption of the vehicle. The total power consumption of the vehicle is used to determine the expected range, which is output on a display located in the passenger cabin for reference by the driver.

    Abstract: A temperature protection device basically includes a temperature detector, a temperature estimator, an overheated determining component and an overheating protection component. The temperature detector detects a temperature of a semiconductor component. The temperature estimator estimates an estimated temperature of the semiconductor component. The overheated determining component determines whether the semiconductor component is in an overheated state based on the detected temperature and the estimated temperature by using a first estimated temperature as the estimated temperature at a time point when the detected temperature has reached a first threshold temperature and a second estimated temperature that is estimated subsequent to the time point as the estimated temperature when the detected temperature has reached the first threshold temperature.

  • Patent number: 8914173
    Abstract: A method and system for conditioning an energy storage system (ESS) for a vehicle, like a high-voltage battery or a fuel cell used for vehicle propulsion. It may be detrimental for a high-voltage battery in a parked vehicle to be exposed to extreme temperatures for an extended period of time. Thus, the method and system may be used to condition such a battery—for example, by heating it up if it is too cold or by cooling it down if it is too hot—so that the performance, durability, lifespan and/or other aspects of the battery are improved. In an exemplary embodiment, the method predicts if the battery will need conditioning the next time the vehicle is parked and, if such conditioning is needed, then the method predicts if the battery has sufficient charge to perform this conditioning. If the charge appears insufficient, then the method operates an energy generator that provides additional charge to the battery in anticipation of the needed conditioning.
