To suppress current fluctuations upon commencement of driving and prolong lifespan by reducing electric stress caused by current fluctuations.A glow plug 1, a glow switch 2, and a stabilizing coil 3 are series-connected, and upon commencement of the driving of the glow plug 1, a repetition frequency of PWM signals that control the opening and closing of the glow switch 2 is made into a higher frequency than a repetition frequency in a normal drive state and the opening and closing of the glow switch 2 is controlled (S104), and when a predetermined drive shift condition has been met (S106), the repetition frequency of the PWM signals is returned to the frequency during normal driving and the opening and closing of the glow switch 2 is controlled (S108), whereby the current upon commencement of driving is smoothed and the occurrence of an instantaneous large current is suppressed.

The accuracy in controlling the heating temperature of a glow plug and the reliability of the control operation are improved.An electronic control unit 101 is configured such that a standard applied voltage for glow plugs 50-1 to 50-n is set according to the engine speed and the load conditions of the engine. In addition, a correction coefficient set in advance according to the temperature classification of the mounted glow plugs 50-1 to 50-n is readably stored in the electronic control unit 101 as a correction coefficient map. By multiplying the standard applied voltage by a correction coefficient K read from the correction coefficient map and applying a voltage of the multiplication result to the glow plugs 50-1 to 50-n as a driving voltage through the power circuit 102 to perform driving control, stable and reliable heating temperature control can be realized regardless of variations in the heating temperature characteristics.

A glow plug is provided that can be easily determined as to whether or not it is a new article. An additional circuit formed by connecting a diode, a fuse, and an adjusting resistor in series in this order is connected in parallel to a heating element of a glow plug. The diode is provided so as to have an anode located on the positive electrode side of the heating element and a cathode located on the fuse side. In the case of a unit inspection, by applying a positive voltage for test to a heating element negative electrode connecting portion, it is possible to determine whether or not the glow plug is normal without blowing the fuse before the glow plug is used in a vehicle.

There is provided a new glow plug that can be easily determined as to whether or not it is a new article.An additional circuit 12 formed by connecting a diode 13, a fuse 14, and an adjusting resistor 15 in series in this order is connected in parallel to a heating element 11 of a glow plug 1. The diode 13 is provided so as to have an anode located on the positive electrode side of the heating element 11 and a cathode located on the fuse 14 side. In the case of a unit inspection, by applying a positive voltage for test to a heating element negative electrode connecting portion 3a, it is possible to determine whether or not the glow plug 1 is normal without blowing the fuse 14 before the glow plug 1 is used in a vehicle.
摘要:
The presence or absence of degradation and abnormality is determined with high reliability by measuring a resistance value of a glow plug, which is in an operating state, as a latest resistance value. A method then determines whether or not the rate of the change of the latest resistance value with respect to an initial resistance value of the glow plug exceeds a first predetermined value. The method also determines whether or not the rate of the change of the latest resistance value with respect to a last resistance value that is a resistance value of the glow plug, which has been recently measured at the time of the acquisition of the latest resistance value, exceeds a second predetermined value when the rate of change of the latest resistance value with respect to the initial resistance value of the glow plug exceeds the first predetermined value. The method determines that the glow plug is in an abnormal degradation state when the rate of the change of the latest resistance value with respect to the last resistance value exceeds the second predetermined value.

In order to evaluate the service quality of an application, there are methods which acquire various types of events which occur upon a Web browser upon which an application is operating in order to analyze thereof. On this occasion, if all events are acquired/collected, a load is placed thereby upon the Web browser or a server which records the events. In the present invention, when the Web browser starts the application, a connection is made to an event handler which acquires events related to user operations or application responses. When the event handler detects the occurrence of an event, if the event has not been recorded in the past, the event is recorded as a log. In the case of another event, in case a script has been executed or in case data has been modified, the event is recorded as a log.
摘要:
Operability of a web application comprising dynamic contents is evaluated continuously with high precision. In a web application execution system 1000, a web server apparatus 121 responsive to a request from a client apparatus 101 and a log server apparatus 141 are connected via a network 161. The log server apparatus 141 stores an operation log obtained when the web application is operated on the web browser in accordance with a manual having a description of an operation method of the web application, as a first operation log, stores another operation log obtained when the web application is operated in the client apparatus 101, as a second operation log, and transmits difference information between the first and second operation logs to the web server apparatus 121, the client apparatus 101 or a different external apparatus 181 to cause the difference information to be at least displayed or recorded.
