    Abstract: Part units of speech information are arranged in a predetermined order to generate a sentence unit of a speech information set. To each of a plurality of speech part units of the speech information, an attribute of “interrupt possible after reproduction” with which reproduction of priority interrupt information can be started after the speech part unit of the speech information is reproduced or another attribute of “interrupt impossible after reproduction” with which reproduction of the priority interrupt information cannot be started even after the speech part unit of the speech information is reproduced is set. When the priority interrupt information having a high priority rank than the speech information set being currently reproduced is inputted, if the attribute of the speech information being reproduced at the point in time is “interrupt impossible after reproduction,” then the priority interrupt information is reproduced after the speech information is reproduced.

  • Patent number: 8930036
    Abstract: An electrical network architecture including a reconfigurable interface layer, along with a corresponding reconfiguration methodology. The interface layer is comprised of reconfigurable interface devices which allow a plurality of sensors and actuators to communicate with a plurality of control units. Each sensor or actuator is connected to multiple interface devices, which in turn are connected to a bus. The control units are also connected to the bus. In the event of an interface device failure, other interface devices can be reconfigured to maintain communication between sensors, actuators and control units. In the event of a control unit failure, the interface devices can be reconfigured to route sensor and actuator message traffic to a different control unit which can handle the functions of the failed control unit. The overall number of control units can also be reduced, as each control unit has flexible access to many sensors and actuators.

    Abstract: In a control apparatus for a rotary electric machine receiving power from a DC power supply, a DC-AC converting circuit is provided with serially connected circuits each having high-potential-side and low-potential-side switching elements. When a short-circuit occurs at the switching elements, all the switching elements are turned OFF for failsafe and a path connecting the machine and the battery is opened. In such a case, a switching element belonging to part of the switching elements is turned ON, with potential at all the terminals of the rotary electric machine being the same. A location of the short-circuit occurs is identified, based on changes in current passing through the machine and being detected in response to turning ON the switching element. The changes are at least one of a reduction change in deviation of the current from a zero point and a reduction change in an absolute value of the current.

  • Patent number: 8050821
    Abstract: The present invention provides an improved method and apparatus for regulating state variable estimators used in a hybrid active damping system for a vehicle powertrain. The state estimator provides variable estimates for operating states, such as real-time torque values of axles and dampers, that are not readily measurable with production powertrain and driveline hardware. This facilitates implementation of other control algorithms, such as torque oscillation damping control schemes which use multivariable feedback. The apparatus and method monitors the operating mode of the powertrain, and resets the state estimator for the hybrid active damping ring (HADR) under predetermined operating conditions. For instance, the state estimator includes an array of current state and predicted state variables that are set equal to corresponding reference values or measured values if the powertrain enters into four-wheel drive low (4WDLO).

  • Patent number: 8000859
    Abstract: A solenoid control system for a vehicle comprises a primary controller, a failover controller, and a failover control module. The primary controller generates a first solenoid drive signal based upon a control signal. The failover controller selectively generates a second solenoid drive signal based upon the control signal. The failover control module receives an operating signal that indicates whether the primary controller is functioning properly and selects the second drive signal to drive a solenoid when the operating signal indicates that the primary controller is not functioning properly.

  • Publication number: 20100324781
    Abstract: An aware vehicle network system and method for one or more vehicles each having adaptive active suspensions includes at least one vehicle having a vehicle position detector for determining a vehicle position and a road condition detector for determining road condition information for any given position determined by the vehicle position detector. A transmitter sends the road condition information and the vehicle position over a vehicle communication network. A central network device receives the road condition information and the vehicle position and calculates ideal active suspension parameters based thereon. The network device sends ideal active suspension parameters over the vehicle communication network to at least another vehicle having an adaptive active suspension. The adaptive active suspension is adjusted based on the ideal suspension parameters received from the network device.

  • Patent number: 7788006
    Abstract: In a rollover stability method for a vehicle in a situation which is critical with respect to the driving dynamics, a critical rollover situation is detected by analyzing a control variable and the stabilization intervention is activated or de-activated as a function of the control variable. The regulation intervention is maintained even in driving situations featuring relatively low transverse acceleration if the control variable or a characteristic property of the stability algorithm is calculated as a function of the steering angle and/or the longitudinal vehicle velocity.

  • Patent number: 7756619
    Abstract: An active vibration insulator includes an electromagnetic actuator, a controller, and a bad-roads processor. The electromagnetic actuator generates vibrating forces depending on electric-current supplies. The controller carries out vibrating-forces generation control. In the vibrating-forces generation control, the electric-current supplies are made variable so as to actively inhibit vibrations generated by an on-vehicle vibration generating source of a vehicle from transmitting to a specific part of the vehicle based on cyclic pulsating signals output from the on-vehicle vibration generating source. Thus, the controller lets the electromagnetic actuator generate the vibrating forces. The bad-roads processor stops the vibrating-forces generation control effected by the controller when the vehicle travels on bad roads.
