  • Publication number: 20160039296
    Abstract: The present invention aims to provide a charging and discharging control apparatus that can reduce a period until charging and discharging processing is started while reducing power consumption during non-use, and to provide an electric motor vehicle including the charging and discharging control apparatus. The charging and discharging control apparatus of the present invention predicts, with use of a charging and discharging start predictor, whether a charging and discharging operation including at least one of an operation to charge a storage apparatus and an operation to discharge the storage apparatus is started or not. In accordance with a result of prediction, a manager manages transition of a charging and discharging controller from an activated state to a standby state and from the standby state to the activated state.

  • Patent number: 9139163
    Abstract: An electric-powered vehicle is provided which is capable of charging a battery with stability, and which is capable of limiting the charging of the battery in the event of theft to provide a high degree of effectiveness of preventing theft by using a simple configuration. In the electric-powered vehicle, a vehicle storage section stores therein information, e.g. an ID list, about charging facilities permitted to charge a vehicle-mounted battery. When the electric-powered vehicle is connected to a charging facility, a charging facility ID acquisition section acquires the ID of the charging facility from the charging facility connected thereto. When it is judged that the ID of the charging facility acquired by the charging facility ID acquisition section is included in the ID list of charging facilities stored in the vehicle storage section, a charging request section makes a request to the charging facility for charging of the vehicle-mounted battery.

  • Patent number: 8990545
    Abstract: This is a program analysis technique using a branch history table (BHT). Upon start of a program, a plurality of flags, each corresponding to an instruction of the program, are initialized to a disabled state and an initial state of a BHT is stored. Upon execution of a branch instruction, if a branch has not been taken, a value of history information of a corresponding entry of the BHT is decremented. If the branch has been taken, the value of the history information of the corresponding entry is incremented and whether a corresponding flag is enabled or disabled is determined. If the corresponding flag is disabled, the flag is enabled. Upon termination of the program, a differential history information value of each entry is obtained from the stored initial state and a final state of the BHT. A final state of each flag is obtained.

  • Patent number: 8914200
    Abstract: A control device for a belt type continuously variable transmission device includes primary And secondary pulleys and a belt and controls gear ratio based on a running radius of the belt on a pulley by controlling primary and secondary oil pressures. The transmission includes a belt slip control unit and a belt slip control permission determining unit. The belt slip control unit performs such control as to oscillate the secondary oil pressure, estimates a belt slip condition by monitoring the phase difference between an oscillation component included in an actual secondary oil pressure and an oscillation component included in an actual gear ration, and then reduces the actual secondary oil pressure to maintain a predetermined belt slip condition. The belt slip control permission determining unit permits belt slip control when a transmission rate as a change rate of the gear ratio is less than a predetermined value.

  • Patent number: 8914201
    Abstract: A control device controls a belt type continuously variable transmission including a belt slip controller and a belt slip control permission determining unit. The device decreases belt friction when an estimated accuracy of a belt slip condition is high and prevents a belt from greatly slipping when an estimated accuracy is low. The device includes primary and secondary pulleys and the belt, and controls a gear ratio based on a running radius of the belt on a pulley by controlling primary and secondary oil pressures. The controller oscillates a secondary oil pressure, estimates the belt slip condition by monitoring a phase difference between oscillation components, and reduces an actual secondary oil pressure to maintain a predetermined belt slip condition. The determining unit permits belt slip control when a torque change speed input to the transmission mechanism is less than a predetermined value.

  • Patent number: 8892318
    Abstract: A control device controls a belt type continuously variable transmission including a primary pulley, a secondary pulley, and a belt, and controls a gear ratio based on a primary oil pressure and a secondary oil pressure. The control device includes a belt slip controller which oscillates the secondary oil pressure and monitors a phase difference between an oscillation component included in an actual secondary oil pressure and an oscillation component included in an actual gear ratio to estimate a belt slip state. The controller controls the actual secondary oil pressure to decrease based on the estimation to maintain a predetermined belt slip state. An oscillation amplitude setter sets an oscillation amplitude of the secondary hydraulic pressure small when the gear ratio is high compared with when the gear ratio is low, in a case of oscillating the secondary hydraulic pressure in the belt slip control.
