  • Patent number: 8437933
    Abstract: A hybrid electric vehicle has a first mode in which slippage of a clutch between an electric motor and a driving wheel is allowed and controlled by rotational speed control of the electric motor and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine. When the vehicle is stationary in the first mode, a controller reduces a control setpoint of hydraulic pressure of the clutch from an initial point. The controller identifies a reference point of the control setpoint with which actual output torque of the electric motor is substantially constant with respect to the reduction of the control setpoint. Then, the controller increases the control setpoint to a precharge point, and reduces the control setpoint to a corrected point that is lower than or substantially equal to the initial point and higher than the reference point.

  • Patent number: 8250932
    Abstract: The present invention is intended to make it possible to set security functions as necessary depending on usage environment, etc. and to improve the security functions; a function setting section 1116 sets security function information received from the outside via a communication line as security functions regarding the user of gas. According to the set security function, in the case that the operation conditions of the security function are satisfied, a monitoring section 112 detects a problem during the use of gas and outputs a security signal to a control section 114. Based on the security signal from the monitoring section 112, the control section 114 shuts off the supply of gas in the case that a phenomenon satisfying an operation condition of the set function having been set has occurred.

    Abstract: A hybrid electric vehicle has a first mode in which slippage of a clutch between an electric motor and a driving wheel is allowed and controlled by rotational speed control of the electric motor and a second mode in which the slippage of the clutch is allowed and controlled by rotational speed control of an engine. When the vehicle is stationary in the first mode, a controller reduces a control setpoint of hydraulic pressure of the clutch from an initial point. The controller identifies a reference point of the control setpoint with which actual output torque of the electric motor becomes unchanged with respect to the reduction of the control setpoint. Then, the controller increases the control setpoint from the reference point at a higher gradient and then a lower gradient, and then sets the control setpoint to a corrected point below the initial point and above the reference point.

  • Publication number: 20110010110
    Abstract: A challenge to be met by the present invention is to enable appropriate setting of safety function according to a use environment and enhance safety function. An IC card (118) stores data pertaining to the quantity of available gas and at least one safety function program. An IC card reading unit (122) reads information stored in the IC card (118). From the read information, an IC card determination unit (126) determines whether or not the IC card (118) is normal. A safety function detection unit (128) detects a safety function program from the read information and stores the program in a safety function storage unit (130). When the IC card (118) is normal, a function setting unit (116) imparts a safety function program to a monitoring unit (112). A remaining available quantity count unit (124) determines a remaining quantity of available gas from the read quantity of available gas and a flow determined by a flow computing unit (110).

  • Publication number: 20110004353
    Abstract: Setting safety function, as appropriate, according to a user environment is enabled, thereby enhancing safety function. According to selection information from a safety function selection unit 120, a function setting unit 116 sets arbitrary function among a plurality of functions as safety function pertaining to usage of a gas. When operating conditions for safety function are fulfilled, a monitoring unit 112 detects malfunction, which would arise during usage of a gas, and outputs a safety signal to a control unit 114 in accordance with the set safety function. In accordance with a safety signal from the monitoring unit 112, the control unit 114 cuts off a gas supply when an event fulfilling operating conditions for the set function has arisen. When an event fulfilling operating conditions for an unset function has arisen, a communication unit 124 reports occurrence of malfunction pertaining to unset function to the monitoring center 200.
