Definitions
- the present invention relates to a self-diagnosis display device (diag display device) provided in an automobile or a motorcycle.
- FIG. 2 shows the configuration and operation flow of a conventional self-diagnosis display device.
- detection signals from various sensors for detecting the operating state of the engine, on / off signals from the start switch, and the rotation of the crankshaft are used to detect the engine speed and the crankshaft speed.
- the crank pulse signal for calculating the angle is input to the ECU (engine control unit).
- the ECU controls operation such as ignition timing and fuel injection based on a predetermined program or map in response to these signals, and when an abnormality is detected due to disconnection or short circuit, an abnormality display signal Is output to turn on the display lamp to indicate that an abnormal condition has occurred.
- an abnormal condition is detected by itself at the time of starting, a start impossible display is performed.
- this start impossible display operation determines whether an abnormality has occurred due to self-diagnosis (step Sl), and determines whether or not the start switch has been turned on in the abnormal state, depending on whether or not the start switch has been turned on. It is determined whether or not the engine has started (step S2), and if it is a start, a start impossible display is performed (step S3).
- the present invention has been made in consideration of the above-described prior art, and is directed to a self-diagnosis display device capable of performing a start impossible display at the start when an abnormal state is self-detected without using an on / off signal from a start switch. It is intended to be provided. Disclosure of the invention
- signals from various sensors for detecting an operation state and a crank pulse signal for detecting rotation of a crankshaft are input to an ECU, and an operation control signal is output from the ECU.
- a self-diagnosis display device that outputs a start-disabled display signal at the time of start-up in a state where the abnormal state is self-detected, and a start-disabled display signal when a crank pulse signal is input in a state where the abnormal state is self-detected.
- a self-diagnosis display device that outputs a self-diagnosis display.
- abnormality display means for displaying the self-detected abnormal state, and the display mode of the abnormality display means is changed according to the start impossible display signal to display the start impossible state.
- the display lamp when an abnormal state is self-detected, the display lamp is turned on to display the abnormal state, and when an attempt is made to start in this abnormal state, the display mode of the display lamp is changed, for example. To blink The start impossible state can be displayed more.
- FIG. 1 is an explanatory diagram of the configuration and operation flow of the embodiment of the present invention.
- FIG. 2 is an explanatory diagram of the configuration and operation flow of a conventional abnormality display device.
- FIG. 1 is an explanatory diagram of the configuration and operation flow of the embodiment of the present invention.
- detection signals from various sensors for detecting the operating state of the engine for example, intake pressure sensor, throttle opening sensor, cooling water temperature sensor, atmospheric pressure sensor, intake temperature sensor, etc.
- a crank pulse signal for detecting the rotation of the crankshaft and calculating the engine speed and the crank angle is input to an ECU (engine control device).
- the ECU performs operation control such as ignition timing and fuel injection based on a predetermined program or map according to these signals, and outputs an abnormality display signal when any abnormality is detected due to disconnection or short circuit. Turns on the indicator lamp to indicate that an error has occurred.
- a start impossible display is performed.
- step Tl it is determined whether or not the abnormality is caused by the self-diagnosis. This is a step for determining whether a disconnection, a short circuit, or some other failure of the sensor has been detected. If it is determined in step # 1 that there is an abnormality, an abnormality is displayed by, for example, lighting a red lamp.
- step T2 it is determined whether or not there is a crank pulse signal, that is, whether or not the engine is rotating (step T2). This allows the engine to start Determine whether it is in a state. If the engine is in the starting state (YES at T2), a start impossible display is performed (step T3).
- the start impossible display is changed to, for example, a blinking display by changing the display mode of the red lamp for the abnormality display by the self-diagnosis. This allows the user to know that the engine is in an inoperable state.
- the rotation of the engine is detected by the crank pulse signal. It is possible to detect that there is, and output a start impossible display signal to indicate that the engine cannot be started. This makes it possible to perform a non-startable display with a simple configuration using a simple and inexpensive wiring or circuit without using a start switch on / off signal.
