In more detail, the present invention relates to An automatic detecting device for calculating the rotational speed and phase angle of the rotating mechanism is a corresponding rotational speed phase angle relationship and a rotational speed phase angle signal. [Prior Art] With the high environmental awareness, the internal combustion engine has gradually evolved into an electronic fuel injection control engine. In the electronic fuel injection unit (10), the electronic control unit (10) C〇ntr〇1 Unit; ECU), in order to achieve more Low pollution emissions, and step-by-step improvement of output efficiency, must be precisely controlled for the operating state of the engine. It is common practice to perceive the operating state of the engine through sophisticated sensors such as the crankshaft position sensor ( Crankshaft P〇siti〇n Sens〇r), Camshaft Position Sensor, Wheel Speed Sensor, Throttle Position Sensor, Intake Manifold Absolute Pressure Sensor, Temperature Sensing One of the most important foundations of the fuel supply and ignition timing of the engine ECU for the engine, the dump sensor, the oxygen sensor and the knock sensor is the engine speed and phase angle information. In general, the engine speed and phase angle information is obtained only by mounting a speed sensing component fixed to the engine crankshaft or camshaft. The speed sensing component can be a Hall element, variable magnetic. Variable Reiuctance, Pickup Coil, Magnet Resistor, Photointerrupter, Photocoupler, etc. and other equivalent components, the sensing object is a complex tooth rotation The mechanism has a plurality of recesses or protrusions, wherein each of the recesses may be one of a notch and a slot on the rotating mechanism 201135234, and each of the protrusions may be a protrusion on the rotating mechanism Tooth, one of the plurality of recesses and the protrusions will form a feature to allow the ECU to be identified as a specific angle of rotation, wherein the feature may be a recess of different width, a protrusion, a recess that does not exist And the convex portion is used as another feature for identifying, and the ECU can determine whether the rotating mechanism has rotated one turn and rotate to a specific phase angle through the sensing signal difference of the characteristic portion. Figure 1A is a schematic view of a 12&1 tooth rotation mechanism, comprising a rotating mechanism 10, eleven convex tooth portions 12, a feature portion 14A, and a rotational speed sensing element 16, wherein 丨2& The 1 tooth system represents that the rotating mechanism 1〇 is equally divided into 12 convex teeth, but one of the convex teeth does not exist, and becomes a characteristic portion of the rotating mechanism 1〇. When the rotating mechanism 10 rotates, if the characteristic portion 14 turns through the rotational speed sensing element 16, the rotational speed sensing element 16 will not output a pulse signal because the characteristic portion 14 is a non-existent convex tooth portion. Reacting, and when each of the other convex tooth portions 12 rotates through the rotational speed sensing member 16, a pulse signal is output, and the output pulse signal is electrically connected to an ECU (not shown) for following the feature. The part is a non-existent convex tooth portion 'no response of the output pulse signal to determine and calculate the rotational speed and phase angle of the rotating mechanism (7). Figure 4 shows a schematic diagram of a 2&2 tooth rotation mechanism, including a rotating mechanism 、), ten convex tooth portions 12, a feature portion 14A, and a rotational speed sensing element 16, wherein 12 & 2 teeth It represents the rotating mechanism. The knives such as the mound are 12 convex teeth, but two of the convex teeth are not present, which becomes the characteristic part of the rotating mechanism 1〇.

The first drawing shows a 6-toothed Η, and the fifth-Μ 12 — the mechanism ^ Including - a rotating mechanism, a solid characteristic portion 142 and a rotational speed sensing element 16, the eight-toothed eight-toothed system represents that the rotating mechanism 1Q is equal to (four) six convex teeth, and (four) one of the convex teeth is wider (or narrower) The characteristic portion (10) of the rotating mechanism 1G is preferably based on the difference between the positive and negative edges of the characteristic portion 142. The rotational speed and phase angle of the rotating mechanism ι are the same as those in the first FIG.

Encapsulating therein, for example, integrating the rotational speed sensing interface with the rotational speed and phase angle calculating unit into one of the same wafer and a package, and the convex teeth in the embodiment may be replaced by a notch, a groove or a magnetic pole. It is not intended to limit the scope of the invention by the mechanism material that is adapted to the sensing element. Furthermore, the storage unit 222 is configured to store a plurality of rotational speed phase angle relationships, and further, the rotational speed phase angle relationship is used to calculate the position of the characteristic portions of the various rotating mechanisms at the rotational phase angle signal thereof. The position of the characteristic portion calculates the rotational speed and phase angle of each rotating mechanism. Next, how the rotational speed and phase angle calculating unit 224 uses the above-described rotational speed phase angle relationship and the rotational speed phase angle signal 2200 will be described. The rotational speed and phase angle calculating unit 224 is electrically connected to the storage unit 222 and the rotational speed sensing interface 220, and then further determines the type of the rotating mechanism according to a waveform of the rotational phase angle signal 2200, and more specifically, different numbers of teeth. The rotation mechanism has different waveforms. The waveform is based on the difference in the number of convex teeth and the number of features of the rotating mechanism, so that the distance between the characteristic portion and the convex portion of the various phase angle signals of 201135234 is different from the width value of the characteristic portion. Differently, the rotational speed and phase angle calculating unit 224 further selects a corresponding rotational speed phase angle relationship from the rotational speed phase angle relationship according to the type, and finally, according to the corresponding rotational speed phase angle relationship and the The waveform of the rotational phase angle signal calculates the rotational speed and phase angle of the rotating mechanism. More specifically, the rotational speed and phase angle calculation unit 224 can be a central processing unit (CPU), a microcontroller (MCU), a digital signal processor (DSP), and a programmable logic array (FPGA). First, please continue to refer to Figures 3A to 3C, which are schematic diagrams of the 6&1 tooth rotation mechanism, the 6& 2 tooth rotation mechanism and the 6-tooth rotation mechanism of the rotational phase angle signal 2200, further illustrating the rotational speed and phase angle calculation. The unit 222 calculates the position of the feature of the rotating mechanism with different numbers of teeth, and further calculates the rotational speed and phase angle. First, the broken lines in the 3A and 3B drawings indicate that the convex tooth portion does not exist. In Fig. 3A, the difference between the rising edges of the rotational phase angle signals 2200 of the front and rear convex portions of the feature portion is b, the difference between the two convex tooth portions before the feature portion is a, and the two convex tooth portions after the feature portion The difference between the two is c, and the relationship between them can be expressed by the following formula: It should be emphasized that when a rotating mechanism is an M&1 tooth rotating mechanism, the value of Μ is not less than 3, the value of Ν is equal to 1 and Μ and Ν The difference is not less than 2. Where r is the error percentage of the engine engine running acceleration and deceleration, for example, r can be a value between 0% and 50%.
