摘要:
During a shut-down period of an engine based on an idle stop control, a computer estimates a power stroke cylinder and a compression stroke cylinder when the engine is stopped. A fuel is injected into the power stroke cylinder and the compression stroke cylinder in an intake stroke just before the engine is stopped. An air-fuel mixture is hold in each cylinder with the engine stopped. When an auto start is required while the engine is stopped, a spark ignition is performed in the power stroke cylinder to start cranking of the engine by combustion energy. At nest ignition timing, a spark ignition is performed in the compression stroke cylinder to start the engine without an aid of a starter.

An engine stopping and starting control device includes a prediction means, a control means, and a start control means. The prediction means predicts a cylinder on a compression stroke upon a stop during a process for stopping an engine. The control means controls a fuel injection upon a stop that injects fuel into the cylinder during the process for stopping the engine to seal an air-fuel mixture therein. The start control means fires the cylinder to generate a first explosion to start the engine.

An information analysis unit of a management apparatus searches for a device existing within a predetermined distance from a portable terminal, namely a device positioned near the portable terminal, based on terminal position information received from the portable terminal by a radio communication unit and device position information stored in an information storage unit. The information analysis unit reads, from the information storage unit, energy usage information of the searched device existing near the portable terminal, and transmits it from the radio communication unit to an information acquisition unit of the portable terminal. Thus, the information acquisition unit acquires only the energy usage information of the device positioned near the portable terminal, so that a display unit displays only the energy usage information of the device positioned near the portable terminal.

The apparatus management system includes a plurality of environmental control apparatuses, a power supply regulation device and a mobile terminal. Each of the environmental control apparatuses is assigned first identification information for physically distinguishing and logical second identification information. The power supply regulation device regulates the respective power supply to the environmental control apparatuses according to apparatus operation information. The mobile terminal includes a terminal-side storage section for storing a conversion table indicative of the correspondence between the first identification information and the second identification; and a conversion section for extracting, from the conversion table, the second identification information corresponding to the inputted first identification information. The mobile terminal includes an apparatus operation setting section for setting the apparatus operation information in association with the second identification information; and a terminal-side communication section for transmitting the apparatus operation information to the power supply regulation device via wireless communication.
摘要:
In a microcomputer, a signal processing device computes a control signal, such as an accelerator position, a throttle position, based on a sensor output signal, such as an output signal of an accelerator position sensor, an output signal of a throttle position sensor. A torque control device executes a torque control operation to coincide an actual torque with a requested torque based on the control signal. Furthermore, a torque monitor device determines whether a torque increase abnormality exists based on the control signal. A signal abnormality diagnosis device determines whether an operational abnormality of the signal processing device exists based on a relationship between the sensor output signal and the control signal. A monitor IC monitors operational states of the torque monitor device and of the signal abnormality diagnosis device and determines whether an operational abnormality of the torque monitor device or of the signal abnormality diagnosis device exists.

A fuel cut failsafe function monitoring section of a microcomputer sets a fuel cut failsafe function diagnosis period in a period, in which an operation of an engine is stopped (e.g., a period before engine start), and sends a fuel cut failsafe execution command signal to a fuel cut failsafe execution section of an abnormality monitoring device during the fuel cut failsafe function diagnosis period. Thus, the fuel cut failsafe execution section is caused to output a fuel cut failsafe signal to an injector driver to stop an operation of the injector driver. The fuel cut failsafe function monitoring section monitors an output level of a disablement port of the injector driver at the time, thereby performing abnormality diagnosis of a fuel cut failsafe function.

A reference voltage generating circuit is constituted by resistors RE and RF each having a resistance not influenced by an application of pressure. The reference voltage generating circuit is connected between one and the other ends of a bridge circuit. A failure judgement of the bridge circuit is performed based on a comparison of a voltage difference VBC between two midpoints B and C of the bridge circuit and voltage differences VCE and VBE between a reference voltage level of the reference voltage generating circuit and the voltage levels of two midpoints B and C.

Apparatus control system includes control device controlling operation of apparatuses and portable mobile terminal communicable with the control device. In the control device, control unit controls each apparatus in accordance with control schedule stored in device-side storage unit and control request from the mobile terminal. In the mobile terminal, date and time setting unit sets arbitrary date and time as set date and time. Terminal-side storage unit stores terminal-side schedule in which control contents are associated with control dates and times for each apparatus. Simulation unit simulates operating state of each apparatus assuming that the apparatus is operating at the set date and time set by the date and time setting unit, using the terminal-side schedule. Apparatus state reflection unit outputs control request to the control device to cause the control device to control each apparatus such that the apparatus is in the operating state simulated by the simulation unit.

An energy conservation diagnosis system manages electrical device K which consumes electricity to operate based on control schedule information, and includes acquiring unit 14a, rule information generation unit 14b, operating determination unit 14c and display unit 12. Acquiring unit acquires operating information obtained by relating an operating condition of electrical device to a clock time. Rule information generation unit generates rule information by relating a rule on use of electrical device to a clock time, based on one or more predetermined time slots depending on a benefit of electricity consumed by electrical device. Operating determination unit acquires control schedule information of electrical device, and generates an image data by superimposing acquired control schedule information and rule information onto operating information so that each clock time is fitted to a clock time of operating information. Display unit displays the image data.

Apparatus administration system includes control device that controls operation of apparatuses and display device communicable with the control device. In the control device, control unit controls each apparatus in accordance with operation schedule stored in schedule storage unit. Operation history storage unit stores operation history in which past operation states are associated with operated dates and times. In the display device, information acquisition unit acquires the operation schedule and the operation history from the control device. Date and time setting unit specifies past date and time to set as set date and time. Estimation unit estimates operation state at the set date and time through the operation schedule. Extraction unit extracts actual operation state at the set date and time from the operation history. Display unit displays the operation state under schedule control and the actual operation state adjacently.
