  • Patent number: 10279688
    Abstract: A charge-discharge control device charges a power storage device when the charge-discharge control device acquires no warming-up operation command. The charge-discharge control device, when the charge-discharge control device acquires the warming-up operation command, performs warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via a first discharger. When a determiner determines during the warming-up operation that an amount of power discharged via the first discharger does not satisfy a criterion, the charge-discharge control device performs the warming-up operation by repeated alternatingly charging the power storage device and discharging the power storage device via a second discharger.

  • Patent number: 10232698
    Abstract: A mode transition control device a hybrid vehicle has a transmission control unit that prevents a second power generation system from overheating while traveling in a series HEV mode. When a battery is at a power generation request threshold value or lower, the vehicle travels in a “series HEV mode,” in which the first electric motor is utilized as a drive source and receives electrical power from the second motor/generator and the battery. The transmission control unit controls the traveling mode to transition from the “series HEV mode” to a “parallel HEV mode” when the vehicle speed has reached a switchover vehicle speed. When a temperature rise of the second power generation system is predicted while traveling in the “series HEV mode,” the transmission control unit changes the switchover vehicle speed to a slower switchover vehicle speed that was used prior to a determination of the temperature rise.

  • Patent number: 10220826
    Abstract: A drive control apparatus includes a motor control unit and a gear shift control unit, and controls a power transmission system including first and second motors and a gear shift mechanism. When the gear shift mechanism is changed from a first gear stage to a second gear stage during deceleration of the vehicle, the motor control unit controls the first motor to be at a target rotation speed determined based on a gear ratio of a second power transmission gear and a rotation speed of an output shaft, and controls a second motor such that required brake torque is generated by the second motor. The gear shift control unit controls the gear shift mechanism so as to be in a neutral state in which power is not transmitted between an input shaft and the output shaft, until a rotation speed of the first motor becomes the target rotation speed.

  • Patent number: 10220831
    Abstract: A system and method are provided for hybrid electric internal combustion engine applications in which a motor-generator, a narrow switchable coupling and a torque transfer unit therebetween are arranged and positioned in the constrained environment at the front of an engine in applications such as commercial vehicles, off-road vehicles and stationary engine installations. The motor-generator is preferably positioned laterally offset from the switchable coupling, which is co-axially-arranged with the front end of the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated by the motor-generator when the coupling is engaged.

  • Patent number: 10220832
    Abstract: A vehicle includes a rotary electric machine, an internal combustion engine, a temperature sensor, and a limiter. The rotary electric machine generates power to move the vehicle. The internal combustion engine is started by the rotary electric machine to generate power to move the vehicle. The temperature sensor detects temperature of the rotary electric machine or of a drive circuit for the rotary electric machine. The limiter restricts the power generated by the rotary electric machine if the temperature is higher than a first threshold temperature. The start prohibitor prohibits the rotary electric machine from starting the internal combustion engine if the temperature is higher than a second threshold temperature which is higher than the first threshold temperature.

  • Patent number: 10214196
    Abstract: The electronic control unit sets a target value of a charging amount of the electrical storage device and increases the charging amount to the target value during traveling on the freeway. The electronic control unit computes a first travel cost being cost per unit travel distance of fuel used when the EV travel is made by using the electric power charged in the electrical storage device at a time when the HV travel is made on the freeway, and the second travel cost being cost per unit travel distance of the electric power used when the EV travel is made by using the electric power charged in the electrical storage device by the charging mechanism at the destination. The electronic control unit sets the target value on the basis of a comparison result between the first travel cost and the second travel cost.

  • Patent number: 10199973
    Abstract: Embodiments of the present invention are directed to a controller that is configured to limit the rate of change of speed of a motor (e.g., the acceleration or deceleration) regardless of the operating mode of the motor (e.g., speed, torque, or power control mode). The controller can include an acceleration estimator which monitors the output speed of a motor and provides an acceleration-limited speed set point. The output of the acceleration estimator may be limited to a range of acceptable acceleration values that correspond to the required limits of acceleration and deceleration. The acceleration estimator can be configured such that it causes the speed regulator to override the torque and/or power regulators when the acceleration range is exceeded.
