摘要： An electric drive unit is provided having an electric motor-generator coupled with a torque converter. Vehicles and machines employing the same, as well as methods of using the same, are also disclosed. The motor-generator may be configured to selectively drive a rotatable shaft with a motor output torque and generate electrical power from rotation of the rotatable shaft. The electric drive unit may further include a torque converter having an input and an output separated by a fluid coupling. The fluid coupling may be configured to selectively multiply torque received at the input such that a drive unit output torque at the output is selectively increased in at least a predetermined rotational speed range of the electric motor-generator.

摘要： A charge/discharge system includes a controller to control an electric power converter placed between a capacitor and a secondary battery connected in parallel. The controller includes: a request power calculation unit configured to calculate request input/output power for the electric motor generator based on current and voltage of the capacitor and input output current of the electric power converter; a capacitor discharging bias factor map configured to specify a ratio of electric power to be supplied from the capacitor to the electric motor generator to the request input power of the electric motor generator; a capacitor charging bias factor map configured to specify a ratio of electric power to be stored in the capacitor from the electric motor generator to the request output power of the electric motor generator; and a subtraction unit configured to calculate charge/discharge power of the secondary battery by subtracting, from the request input/output power, the charge/discharge power of the capacitor.

摘要： A hybrid vehicle is provided. The hybrid vehicle includes an acceleration pedal, an engine configured to generate an engine torque based on a position of the acceleration pedal, an electronic control unit communicatively coupled to the engine and configured to calculate a target torque based on the position of the acceleration pedal, and estimate a motor-generated (MG)-assist torque based on difference between the target torque and the engine torque, a motor generator communicatively coupled to the electronic control unit and configured to generate the estimated MG-assist torque, and a power distribution unit configured to deliver the generated MG-assist torque combined with the engine torque to one or more wheels.

摘要： A vehicle includes: a power reception unit that receives electric power contactlessly from a power transmission unit externally provided; and an electronic device. The power reception unit includes a coil formed to surround a winding axis. Assuming that a region extending in a direction in which the winding axis extends from the coil when viewing the coil from above the vehicle is an adjacent region, the electronic device is away from the adjacent region.

摘要： A power transmission device for a hybrid vehicle has a first clutch device (1a) disposed in a drivetrain between an engine (E) and a driving wheel (D). A second clutch device (1b) disposed in a drivetrain extends from a motor (M) to the driving wheel (D). The oil pump (P), connected to the motor (M), supplies oil to a predetermined moving component disposed in the vehicle by using driving power of the motor (M). A transmission (A) is disposed in a drivetrain between the engine (E) and the motor (M) and the driving wheel (D). The transmission adjusts rotation speed of the motor (M). The power transmission device supplying oil by causing the motor (M) to rotate the oil pump (P) at an appropriate rotation speed.

摘要： 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.

摘要： In a drive unit for four-wheel drive vehicle that allows a motor for driving front wheels to be easily installed, a torque of an engine is transmitted to a rear wheel axle via a transmission and a rear propeller shaft, and a torque of a front drive motor is transmitted to a front wheel axle via a front propeller shaft. A front drive unit is disposed between the transmission and the rear wheel axle. A case of the front drive unit houses: a main shaft that transmits to the rear propeller shaft an output torque of the transmission; the front drive motor; and a sub-shaft that is disposed in a position shifted in a vehicle width direction with respect to the main shaft and transmits to the front propeller shaft an output torque of the front drive motor.

摘要： A method for managing an authorized operating range of a battery, the authorized operating range being limited between a minimum level and a maximum level of state of charge of the battery. The method includes estimating a state of health in power of the battery, the state of health in power characterizing capacity of the battery to supply a minimum required power level across an entirety of the operating range; and determining the minimum level of state of charge of the battery in accordance with the estimated state of health in power, the minimum level of state of charge being increased when the state of health in power decreases.
