  • Patent number: 10308252
    Abstract: To reduce fuel consumption, a transmission is shifted into a neutral state, called neutral idle, when a vehicle stops in a drive mode. During a transition from a neutral idle state to an engaged state, the engine torque is controlled to avoid excessive shift energy and to mitigate acceleration drop. Specifically, the engine torque is set to a level equal to a sum of a transmission torque capacity and an offset, which is a function of accelerator pedal position. The transmission torque capacity is calculated based on the engaging shift element torque capacity and torque ratios associated with the kinematics and the torque converter. To accommodate noise factors such as variation over time, the offset function is adapted in response to measured clutch energy and acceleration drop.

    Abstract: A vehicle includes a traction battery and a controller programmed to, in response to a first ignition cycle after a charging of the traction battery, output a distance until charge prediction based on one or more selected distance estimates from filtered sets of historical data that are derived by filtering historical data based on a time and a day of the first ignition cycle. The selected distance estimates may be from filtered sets having more than a predetermined number of members. The selected distance estimates may be from filtered sets having a variance that is less than an overall historic variance. The filtered sets may include members of an unfiltered set based on a time of day and day of week.

  • Patent number: 10118606
    Abstract: An apparatus includes an unit that plans any driving mode of an EV mode in which the motor is used as the drive source and an HV mode in which at least the engine is used as the drive source for each section, into which a route from the current location to the destination is partitioned, when a load for running in each section is set. The setup unit plans the mode using an aspect in which the HV mode is preferentially planned for a section including at least one of a current section including the current location and a section after the current section when a remaining amount of the battery is lower than a threshold of the remaining amount of the battery, and regenerative energy obtained from running load information is higher than or equal to a value determining a restoration of the remaining amount of the battery.

  • Patent number: 10100493
    Abstract: A shovel according to an embodiment of the present invention includes an engine; a motor generator that functions as a motor that uses a drive force of the engine and functions as a motor capable of assisting the engine; a power storage system, a swiveling motor; a DC bus that connects the motor generator, the power storage system, and the swiveling motor; and a controller that controls movements of the motor generator, the power storage system, and the swiveling motor. In a case where the power storage system is stopped, the controller supplies electric power of the motor generator that functions as the power generator to the swiveling motor when the swiveling motor is in a power running operation, and supplies regenerative electric power of the swiveling motor to the motor generator that functions as the motor when the swiveling motor is in a regenerative operation.

  • Patent number: 10000364
    Abstract: In a vehicle having a vehicle body frame from which left and right front wheels are suspended, a winch is mounted so as to be disposed between the front wheels and configured to appropriately wire a plurality of conductors to a contactor interposed between the winch and a battery. Winch positive and negative side terminals, a battery positive side terminal and a grounding negative side terminal are disposed in a concentrated manner on a terminal disposition face of the contactor. Winch positive and negative side conductors extend from the contactor to the winch side. A battery positive side conductor and a grounding conductor extend from the contactor in directions different from the extending direction of the winch positive and negative side conductors from the contactor and different from each other.

  • Patent number: 9994214
    Abstract: A drivability target engine speed is set based on a shift stage based on an accelerator opening level and a vehicle speed and the vehicle speed, and a base driving force is set based on an accelerator required driving force and the drivability target engine speed. When an elapsed time after an accelerator depression amount increases is less than a threshold value, a correction driving force is set based on an increase in accelerator depression amount and an engine, a first motor, and a second motor are controlled such that an effective driving force obtained by adding the correction driving force to the base driving force is output to a drive shaft for a hybrid vehicle to travel.

  • Patent number: 9956951
    Abstract: An apparatus and method for controlling cold starting of a mild hybrid vehicle, are disclosed. The method includes: measuring, by a sensor, a cooling water temperature of the vehicle when a request is received to start an engine; operating, by a controller, a starter to drive an engine when the cooling water temperature is less than a preset reference temperature, and stopping the operation of the starter and operating an MHSG to drive the engine when RPM of the engine driven by the starter exceeds a preset reference value. In particular, stepwise starting according to the cold starting of the vehicle is performed. The apparatus and the method are advantageous in that a starter and alternator are simultaneously controlled under a cold starting condition to provide startability and reduce capacity of a starter, reducing manufacturing costs.
