  • Publication number: 20180017004
    Abstract: Provided is a knock detecting device capable of ensuring knock detection accuracy irrespective of fuel injection conditions even when a period during which injection-valve noise occurs overlaps with a knock determination period. An ECU 9 subjects signals output from a knock sensor, which detects vibrations of an internal combustion engine, to frequency analysis to calculate frequency components (501). The ECU 9 calculates a background level that indicates the average of the frequency components (503). The ECU 9 stores, in association with each other, the number of fuel injections, which indicates the number of fuel injections in a predetermined time period during one combustion cycle, with a learning value, which indicates a frequency-component correction amount (507).

  • Publication number: 20170227971
    Abstract: Infrastructure clarity of a planned section that is a road section included in a planned travel route is specified based on infrastructure clarity information. The infrastructure clarity is clarity of a road infrastructure that is used as a detection object by a lane detection apparatus. The infrastructure clarity information is information recording the infrastructure clarity for a plurality of lanes for one-way traffic on a per road section basis. A road link used in a map database is adopted as the road section. Control contents of autonomous travel in the planned travel route are set based on the infrastructure clarity of the planned section and an autonomy level condition. The autonomy level condition is a condition by which control contents at a higher level are selected among a plurality of autonomy levels as the infrastructure clarity becomes higher.

  • Publication number: 20160234089
    Abstract: A wireless communication system includes a machine to machine (M2M) device, and a base station that performs wireless communication with the M2M device. The M2M device includes a check-signal transmitting unit that transmits, after a bearer in a wireless section between itself and the base station is released, a check signal to the base station every first period by wireless communication using a frequency that is used in the bearer. The base station includes a determining unit and a notifying unit. The determining unit determines whether there is an abnormality in wireless connection between itself and the M2M device based on whether a check signal is received from the M2M device within a second period. The notifying unit notifies, when the determining unit determines that there is an abnormality in the wireless connection between itself and the M2M device, the abnormality to a predetermined notification destination.

  • Patent number: 9097194
    Abstract: Control device of an internal combustion engine that determines whether or not to perform sensor element heating control of an air-fuel ratio sensor with high accuracy based on the mass of condensed water in an exhaust pipe. The control device computes the rate of change of condensed water mass in an exhaust pipe based on the saturated water vapor pressure and the water vapor partial pressure of exhaust gas, and computes the rate of change of evaporation mass in the exhaust pipe based on the amount of heat which the condensed water receives in the exhaust pipe. The control device updates the mass of condensed water based on the rate of change of condensed water mass and the rate of change of evaporation mass, and determines whether or not to perform heating control by a heating controlling unit based on the updated mass of condensed water.

  • Patent number: 8136344
    Abstract: At the start-up of an engine, the ignition timing and the air-fuel ratio are controlled to prevent overload onto the volume of ISC air and decreased torque and torque difference. The fuel condition based on the amount of ignition timing correction to inhibit rotational fluctuation during idling is determined and the fuel quantity based on the result is corrected. Right after an engine has started and until a pilot burner is created in the heat spot of the catalyst, the ignition retard control is mainly executed, and at the time when it is determined that a pilot burner has been created in the catalyst's heat spot, the lean air-fuel ratio control is to be executed instead of the ignition retard control. Furthermore, when the ignition retard control changes to the lean air-fuel ratio control, the state transition control is executed along the equivalent ISC air volume line so as not to cause torque fluctuation.

  • Patent number: 7679666
    Abstract: In a solid-state image-sensing device, after completion of image sensing by individual pixels, in each pixel, a signal ?VRB fed to a capacitor C1 connected to the gate of a first MOS transistor T1 is turned to a high level to make it easy for a negative electric charge to flow into the MOS transistor T1. This permits quick recombination of the positive electric charges accumulated at the drain and gate of the MOS transistor T1, at the gate of a MOS transistor T2, at the anode of a photodiode, and in a capacitor C2, and thereby makes quick resetting possible.

  • Patent number: 7495271
    Abstract: In a solid-state image-sensing device, when image sensing is performed, in each pixel, MOS transistors T1 and T5 are turned on and a MOS transistor T6 is turned off so that a MOS transistor T2 operates in a subthreshold region. When resetting is preformed, in each pixel, the MOS transistors T1 and T5 are turned off and the MOS transistor T6 is turned on so that the gate voltage of the MOS transistor T2 is kept constant. In this state, the MOS transistor T2 is brought first into a conducting state and then, by turning a signal ?VPS to a high level, into a cut-off state. This permits a signal proportional to the threshold value of the MOS transistor T2 to be output as compensation data.

  • Publication number: 20080045244
    Abstract: A radio base station apparatus includes a plurality of call processing controllers for call processing control, a supervision controller supervising the call processing controllers, and a system data memory storing system data necessary for restarting. Each call processing controller includes a plurality of function portions and a memory storing data necessary for restarting. One function portion in one call processing controller includes a reset type recorder recording either an overall radio base station reset, one call processing controller reset only, or one function portion reset in the one call processing controller. Depending on the above recorded reset type, the one function portion initiates by reading data necessary for restarting from the system data memory or the memory in the one call processing controller.

  • Publication number: 20080045206
    Abstract: For each of a plurality of call processing control units constituting the radio base station equipment, an initiation condition minimally necessary for restarting call processing is set. A maintenance supervision and control unit in the base station decides whether each call processing control unit satisfies the above initiation condition. Even when the entire plurality of call processing control units do not satisfy the initiation condition, the call processing control is made to restart only in the call processing control unit having satisfied the initiation condition. Thus, the suspension time in the base station is reduced, restraining the influence upon users to the minimum.
