摘要:
If it is determined that a brake pedal is pressed while an accelerator pedal is pressed, accelerator position limit control for bringing an accelerator position for engine control to a limit value corresponding to vehicle speed is performed, thereby securing safety at the time when both of the accelerator pedal and the brake pedal are pressed. If it is determined that the accelerator pedal is pressed after the brake pedal is pressed, the accelerator position limit control is prohibited, thereby responding to driver's intention to accelerate. If it is determined that the pressing of the brake pedal is cancelled during execution of the accelerator position limit control, accelerator position recovery control for returning the accelerator position for the engine control to an actual accelerator position is performed, thereby recovering normal running corresponding to the driver's intention to accelerate.

According to the present invention, a monitoring system for an internal combustion engine includes a fuel injection control means for outputting a fuel injection signal to an injector based on a target fuel injection quantity and a target fuel injection timing according to a driving condition of the engine. The monitoring system further includes a computation means for computing an actual fuel injection quantity and an actual fuel injection timing based on the fuel injection signal, and a determination means for determining whether a fuel injection malfunction exists by comparing the actual fuel injection quantity and the target fuel injection quantity and comparing the actual fuel injection timing and the target fuel injection timing.

An environmental apparatus control system assures a consistent temperature control for realizing a comfortable residential environment based upon demands from the residents, yet in an energy-saving manner. The system includes an apparatus for controlling a residential space, and an initializer which provides an initial target value for control of the residential space at the start of operating the system. Comfortableness demands from residents are analyzed in order modify the initial target value to a working target value. The initial target value is shifted in a direction of saving the energy such that the working target value can always approach from and settle on the energy-saving side as the demands from the residents are analyzed. The working target values within a past time period are weighted to give a corrected target value which replaces the initial target value for the start of next operation cycle of the system.

An environmental apparatus control system provides and transmits a message voluntarily to each resident as to the current control being made to residential space or environment in which the residents are presence. The system includes an apparatus for controlling the residential environment and a plurality of personal terminals belonging to individual residents in the residential environment. Each terminal is utilized to enter one of opposed demands with regard to the residential environment. The system analyzes which one of the opposed demands is predominant and determines a control project of controlling the apparatus in a direction of satisfying the predominant demand. An information provider is included in the system to provide a message indicating the number of each one of the opposed demands, and transmit the message to the personal terminals voluntarily. Thus, each resident can be regularly informed of the control project or how the control is made in consideration of the demands from the individual residents without making any particular requesting action.
摘要:
An environmental apparatus control system for a comfortable residential environment based upon demands from the residents. The system includes a project composer which relies upon a first reference (R1) and a second reference (R2) to determine a control project based upon the demands. The references are each determined by a first proportion of the count of the temperature lowering demands in the total number of the residents, and a second proportion of the count of the temperature raising demands in the total number of the resident. A first proportion of the count of the first demands in the number of the residents, and a second proportion of the count of the second demands in the number of the residents are obtained to give a current demand ratio which is compared with first and second references for determination of the control project. The first and second references and are defined respectively as different ratios of the first proportion to the second proportion.
摘要:
A control apparatus for an engine increases an intake air quantity just before engine stop to increase a compression pressure in a compression stroke. As the compression pressure is increased, a negative torque in the compression stroke increases and obstructs engine rotation, and brakes the engine rotation. Thus, a range of crank angle, in which torque is below engine friction, that is, in which engine rotation can be stopped, is reduced. As a result, variation in engine rotation stop position is reduced to be within a small range of crank angle. Information of engine rotation stop position is stored, and the stored information of engine rotation stop position is used at the start of an engine to accurately determine an initial injection cylinder and an initial ignition cylinder to start the engine.

A pressure sensor for detecting a pressure such as a brake oil pressure in an automobile is composed of a cylindrical stem, a sensor chip and a circuit board for processing an electrical signal from the sensor chip. The cylindrical stem includes a thin diaphragm formed at an axial end and an opening formed at the other axial end. The sensor chip is mounted on the diaphragm, and the circuit board is mounted on a flat side surface formed on the outer periphery of the cylindrical stem so that the circuit board is positioned perpendicularly to the sensor chip, thereby reducing a size of the pressure sensor in the radial direction of the stem. The pressure to be detected is introduced into the cylindrical stem from its opening, and the pressure is detected by the sensor chip mounted on the diaphragm.

A terminal device sets a beneficial use time slot for regarding the electrical consumption in the beneficial use time slot as the beneficial, a waste use time slot for regarding the electrical consumption in the waste use time slot as the waste, and an efficiency improvement time slot for regarding the electrical consumption in the efficiency improvement time slot as the electrical consumption to be reduced. On the basis of the data of an amount of the electrical consumption of the device to be monitored, calculating an amount of the electrical consumption in each the time slot and displaying an amount of the electrical consumption in each time slot are preformed.

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.

An energy conservation diagnosis system manages electrical device K which consumes electricity to operate based on control schedule information, and comprises acquiring unit 14a, rule information generation unit 14b, operating determination unit 14c and display unit 12. Acquiring unit acquires operating information obtained by means of relating an operating condition of electrical device to a clock time. Rule information generation unit generates rule information by means of 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 means of 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.
