Abstract: There is provided a system and a computer-implemented method for storing electrical charge in an electric vehicle connected to a charging station. The method includes: attaining a minimum State of Charge (SOC) for the electric vehicle; determining a time to charge the electric vehicle to a maximum SOC; maintaining an electric vehicle SOC by repeatedly charging and allowing discharge of the electric vehicle between the minimum SOC and a threshold; and charging the electric vehicle to the maximum SOC when the determined time to charge the electric vehicle to a maximum SOC has elapsed, wherein the threshold is greater than the minimum SOC and the maximum SOC is greater than or equal to the threshold.

Abstract: In a hybrid drive apparatus, a first planetary gear mechanism transmits rotation of a first main shaft to which the engine driving force is inputted to a main speed-changing part at an equal speed due to engagement of a first clutch, and transmits the rotation of the first main shaft to the main speed-changing part and a first motor/generator at an increased speed due to engagement of a second clutch. This enables the range of gear ratios of the transmission to be extended and the degree of freedom in setting a gear ratio or a step ratio to be increased, and enhances the power generation efficiency by rotating the first motor/generator at a high speed without using a special speed increase device.

Abstract: A car system and control method in which transmission shifting is controlled such that synchronizer damage is avoided. A state discrimination device detects or infers the state of each frictional surface of the synchronizers. A synchronizer for forming an intermediate transfer path is selected according to a parameter indicating the state of the frictional surface detected or inferred by the state discrimination device. Engine torque control reduces the engine torque according to a parameter indicating the state detected or inferred by the state discrimination device.

Abstract: When shifting the gear position into a target gear position from a current gear position, some gear position different from said current gear position is used as one distributing gear position. The control unit controls the pressing load of a synchromesh of one distributing gear position to make at least part of the rotation torque from the drive power source transfer by the friction. Thereby it makes at least part of the rotation torque transferred by a synchromesh of the current gear position decrease. And then it moves the synchromesh of said current gear position to a disengaging position not meshed with said idle gear. Thereafter another gear position different from said target gear position and said one distributing gear position is used as another distributing gear position.

Abstract: A power transmission system is provided which can prevent a feeling of inertia travel due to torque transmission interruption occurring when a dog clutch is engaged to shift the speed position, without increasing the axial length of a transmission. An input shaft is connected to a prime mover via a main clutch. Gear pairs are formed by input and output gears arranged on the input shaft and output shafts, respectively. A dog clutch connects one of the gear pairs to the input or output shaft. An auxiliary shaft is connected to the prime mover. Transmission paths are formed on the auxiliary shaft for transmitting the driving force of the prime mover to the output shaft at different gear ratios. In shifting the speed position, an assist clutch supplies the driving force to the output shaft via the auxiliary shaft and a selected transmission path.

The engine torque control means 303 reduces the engine torque according to a parameter indicating the state detected or inferred by the state discrimination means 301.

Abstract: In a changing system in a manual transmission in which a reverse idling gear is slid and meshed simultaneously with a first reverse gear secured to one of a main shaft and a counter shaft and with a second reverse gear mounted on a sleeve of a preselected synchronizing mechanism mounted on the other of the main shaft and the counter shaft, thereby establishing a reverse speed stage, an interlock plate is formed into a shape for inhibiting the movement of a preselected shifting piece in the same direction as a direction of sliding of the reverse idling gear, when a shifting arm having a drive portion engaged with a reverse shifting piece is turned for shifting to establish a reverse speed stage. Thus, it is possible to inhibit the movement of the sleeve of the preselected synchronizing mechanism, when the reverse speed stage is to be established.
