Abstract

A start control device of an internal combustion engine capable of realizing a more efficient start control of the engine by recognizing the absolute angle of an engine crank shaft, wherein the absolute angle of the crankshaft (13) is calculated based on the ignition reference signal of the engine and the commutation position pulse signal of a starter motor (10) and the starter motor (10) is controlled based on the absolute angle. The starter motor (10) is rotated reversely based on the calculated absolute angle, and rotated forwardly to start the engine after the crankshaft (13) is temporarily rotated reversely to an expansion stroke, whereby, because the timing of the crankshaft (13) from reverse to forward rotation is controlled accurately by the absolute angle to enable an efficient engine start control, an efficient inertia start control can be realized, and the absolute angle of the crankshaft (13) of the engine can be recognized accurately by a crank angle detector without increasing the number of reluctors (40).

Description of the Invention (I) Field of the Invention The present invention relates to a starting device and a starting control device for an internal combustion engine, and is suitable for starting an internal combustion engine of a two-wheeled vehicle or a four-wheeled vehicle. In particular, it relates to a crank angle detection device for an internal combustion engine of a two-wheeled vehicle or a four-wheeled vehicle. BACKGROUND OF THE INVENTION The starting of an engine (internal combustion engine) has a mixture of fuel intake gas, compression and explosion, and uses a battery as a drive source, and then uses the rotation of the crankshaft axis to maintain the rotational external force required when the engine starts. The conventional starting method is a transmission device that transmits the rotation of the crankshaft axis between the decelerating devices when the engine is rotating, and is directly connected to the engine with the crankshaft axis. The crankshaft axis rotation device intervening in the speed reduction mechanism is provided on the periphery of the engine flywheel, and the auxiliary gear meshes with the ring gear. The auxiliary gear moves forward and backward along the engine axis. When starting, the meshing of the pinion and the ring gear will transmit the rotational force of the crankshaft axis deceleration. After the starting is completed, the disengagement position returns to the original position. Normally, when the engine is stopped, the crankshaft axis will rotate inertly, and during the compression stroke of the engine, the brake acts to generate a compressive load. Once the rotation is stopped, the compressive load will provide a small reaction force in the opposite direction, making the The stop position near the lower end point has receded a little. Also, when the engine is started, the crankshaft axis starts to rotate from a position near the end point under the compression stroke, so it will start from a more retracted position. However, when the crankshaft axis started to rotate from this position and the crankshaft is twisted, when the engine gate is started directly after starting to rotate, the nearby current flows into the crankshaft axis, which adds a compressive load and a maximum of 4 papers.

Description of the invention (>) The compression reaction force is set, which causes the speed of the crankshaft axis to increase. At this time, the torque generation gate torque exceeds the end point on the same torque. And the starting engine may have a torque exceeding the necessary capacity of the gate torque. In particular, the reduction mechanism is a case where the ACG engine is directly connected to the crankshaft axis and the engine is started. Since a large gate torque must occur, there is no problem in using a large and expensive engine. However, when it is used in the case of a magnetic boundary with a magnet, a strong magnetic boundary is bound to occur. Therefore, when ACG operation is performed, the rotation will have a large rotational resistance, which will cause the reduction of fuel consumption and output energy, which will cause problems. In addition, a general engine (internal combustion engine) has a continuous stroke such as a mixture of fuel intake, compression, ignition, burst, and exhaust, which can be obtained through rotation output of a crankshaft axis. Therefore, the control of the ignition timing and the timing of opening the valve, or the control of the number of engine revolutions must be controlled by signals. Therefore, most engines use a reference signal composed of the following columns, such as impedance, a protrusion called iron, or a pulse coil as a signal generating device to obtain a pulse signal. This type of engine is formed by the flywheel, the rotor that starts the engine, the crankshaft axis, and the impedance at a specific position of the rotating body that rotates together. On the other hand, a pulse coil is provided on the horizontal side, and the impedance is arranged at a position near the pulse coil. Therefore, when the impedance accompanies the rotation of the crankshaft axis through the vicinity of the pulse line ，, the close contact distance can cause an electrical signal in the opposite direction to the pulse coil to output a pulse signal. Generally, a pulse signal is output at a predetermined crank angle position, which is used as an ignition reference signal to control the ignition timing. Also, it is shaped on the rotating body.

Invention Explanation (3) In the case where one of the aforementioned impedance systems constitutes the mainstream, the pulse signal is output once when the crankshaft axis is rotated once. Therefore, the interval of this pulse signal is calculated based on the number of engine revolutions. This calculation is used to perform various processes such as fuel injection amount control. However, in recent years, as engines have become increasingly high-performance, with the complication of control patterns, the number of rotations of the controller has changed during one rotation of the crankshaft center, so corresponding fine control is necessary. When the aforementioned impedance number is increased, it is necessary to output pulse signals at small angular intervals to obtain high-performance control performance. However, increasing the number of impedances will lead to an increase in the number of processing steps, and it is necessary to use a precise control process to increase the impedance, so the problem of cost increase will occur. The purpose of the present invention is to propose the use of identifying the absolute angle of the crankshaft axis of the engine to implement the engine starting control with better efficiency. In addition, the object of the present invention is to provide identification of a crank angle inspection device without increasing the number of impedances, so as to accurately obtain the absolute angle of the crank axis of the engine. The new regulatory features of the foregoing and other objects of the present invention are clearly described in this specification and the drawings.

The pulse signal uses the above-mentioned absolute angle as a basis to control the characteristics of the aforementioned control device for starting the engine, etc. In the present invention, the absolute angle of the crankshaft axis is used to obtain existing signals such as the ignition reference signal and the pulse signal of the rectified position, and Based on this, the engine is started and controlled. Therefore, the crankshaft angle detector is used to detect the absolute angle of the crankshaft axis. Start the control correctly to achieve better engine starting efficiency. At this time, the aforementioned control device is located at the crankshaft position determined by the aforementioned crankshaft center based on the aforementioned absolute angle. The internal combustion engine is started well. Therefore, the correct timing of the reverse rotation and forward rotation of the crankshaft axis does not help the engine start control, but can perform inertial start control with better efficiency. The crankshaft axis is well inspected, and it is checked that the crankshaft axis has reached a predetermined crank angle position, and then starts to rotate forward. In addition, the aforementioned internal combustion engine is added with the two stroke engines.

Description of the invention (t) The starting point of the absolute angle. When the internal combustion engine is restarted, the position of the crankshaft center is determined based on the absolute angle after stopping. The internal combustion engine can be started well. The control device is stopped after exceeding the compression stroke of the internal combustion engine, and the next time it is started, the target is determined based on the absolute angle obtained before the internal combustion engine is stopped. The crankshaft position of the crankshaft axis can start the internal combustion engine as soon as the forward rotation is applied after the reverse rotation is applied. In addition, the control device first selects a position point during the reverse rotation. At this time, it is preferable to perform preliminary rotation at a position where the crankshaft axis is located on the side of the forward rotation direction where the ignition reference signal is generated. In this way, when the crankshaft axis is reversed, the ignition reference signal generation position is inevitably obtained to obtain the ignition reference signal reliably. In addition, the aforementioned control device uses at least one of battery voltage or engine temperature as a basis to adjust the appropriate reverse stop energization stop position and forward rotation start position of the aforementioned crankshaft axis. In this way, detailed start control based on battery or engine status can shorten start time.

Based on the control of starting the engine, a crank angle detector is attached to accurately control the start using the absolute angle of the crankshaft axis, and achieve better engine starting. At this time, the engine control instruction device is based on the absolute angle, and once the crankshaft position determined by the crankshaft axis is reversely energized, and after the crankshaft angular position determined by the crankshaft axis is reached, or after the inspection After the aforementioned crankshaft axis starts to rotate forward, the forward rotation is appropriately conducted. Further, the aforementioned start control device is provided with a battery voltage detection device for detecting a battery voltage and an engine detection device for detecting an engine temperature. The aforementioned engine control indicating device is adapted to control the aforementioned starting engine based on at least any one of the aforementioned battery voltage or engine temperature and the aforementioned absolute angle. In this way, detailed start control based on battery or engine status can shorten start time. In addition, the forward rotation mentioned herein refers to the normal rotation direction of the engine, and the reverse rotation refers to the rotation direction opposite to the normal rotation direction. The crankshaft angle detection device of the internal combustion engine of the present invention uses a crankshaft angle detection device of the internal combustion engine connected to the crankshaft axis to start the engine by brush starting. An impedance is formed on the rotating body provided on the crankshaft axis, and the aforementioned A reference signal generating device for generating electrical signals according to the aforementioned crankshaft angle and electrical signals generated by the above-mentioned impedance is arranged near the rotating body, and the start of engine rotation is accompanied by the rectified position signal for the start of engine control. 9 Standard (CNS) A4 specification (21〇X 297 public love) (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs.

In the present invention, the absolute angle of the axis of the crankshaft is calculated based on the angle pulse formed by the electrical signal generated by the reference signal generating device and the rectified position signal. Here, you do not need to add impedance or attach a crank angle detector to grasp the current crank angle, and then use the crank angle to implement high-precision engine control. Therefore, there are no factors that increase costs such as increasing the number of processing workers or increasing the number of parts, and they can have corresponding high-performance engine control.

In the state where the engine is stopped and when the engine starts to rotate at 10, the stroke position at which the engine is started is different from the load when starting as shown in Figure 5 (a). During the exhaust stroke or the suction stroke, the suction valve and the exhaust valve are respectively opened to move the piston up and down, and the load when the crankshaft axis 13 is rotated is small. In contrast, when the engine is started in the compression stroke, the suction valve and the exhaust valve are both closed, which makes it difficult for the piston to rise, and increases the rotational load of the crankshaft axis 13. This point is the largest near the upper end point. In the foregoing, when the engine is stopped, the piston usually stops at a position near the end point below the compression stroke. The conventional starting device is to start the engine at this position. When starting, the load of the compression stroke exceeds the crankshaft axis 13 and the necessary energy for starting the engine as shown by the dashed line in Figure 5. The starting device of the present invention starts the engine in a stopped state at the stop position Pa in the normal stop range P shown in FIG. 5 (c). Once the engine reverses through the positions of the intake stroke and the exhaust stroke, it bursts. The crankshaft axis 13 is reversed during the stroke. During this reversal, the piston moves in the opposite direction to the direction indicated by the arrow in the upper column of Figure 5. The piston moves upward at the end point when it is in the position of the suction stroke, and moves downward at the end point when it is in the position of the exhaust stroke. At the position of the burst stroke, it moves up to the end point. Then 'when this reverses to the burst stroke, the suction valve and exhaust valve are both closed.

Invention Description ((G) In the closed state, the gas remaining in the combustion chamber is compressed and the energy of positive rotation is accumulated using the compression reaction force in the combustion chamber. Section 5 (b) The two dotted lines in the figure indicate the energy accumulated by gas compression. Therefore, when the piston is in the normal stop range P when starting, the piston stops at the position of the intake stroke or exhaust stroke, and then starts from this position. Start the engine and perform the same reverse operation described above. When the crankshaft axis 13 is in the forward rotation start range Q of the burst stroke, for example, after the reverse position is finally reversed to the forward rotation position Qa, the crankshaft axis 13 in the engine Starts to turn forward. At this point, burning The positive rotation energy accumulated by the gas compression in the inside is released by the rotation system containing the flywheel of the crankshaft elbow 13, and the energy of the compression reaction force released in the rotation system is added to the energy added by the engine 10. In Section 5 (b ) In the figure, the energy change of the engine added by the crankshaft axis 13 during the normal rotation of the engine 10 is shown by a solid line, and the change of the inertial energy accumulated in the rotating system is shown by a dashed line. The gas energy accumulated in the compression of the rotary system is higher than the inertial energy generated by the reaction force of rapid compression. In the process of the rotational force of the engine 10 from the explosion stroke of the rotary system to the compression stroke, the inertial energy slowly increases. But In the compression stroke, the combined energy of the inertial energy accumulated by the rotating system and the energy of the engine 10 is represented by a thick solid line, and the crankshaft axis 13 is not added. The crankshaft axis 13 is accompanied by a reduction in the number of rotations. It releases the inertia energy consumed in the compression stroke and drives the rotational torque of the engine 10. The maximum overriding torque T is used The maximum energy released by the torque is the maximum of Ti and the maximum torque of the engine.

Description of the invention (η) The load after the initial compression stroke. Figures 6 and 7 Shown is a flow chart of the engine startup control sequence of the present invention. Here, the CPU 32 turns on the ignition switch 39 as usual in step S1, and determines in step S2 whether to turn on the start switch 34. After the start switch 34 is turned on, Proceed to step S3, once the engine reverses. That is, the engine is reversed from the stop position Pa in FIG. 5 to the burst stroke. Next, it is determined in step S4 whether an ignition reference signal is input when the engine is reversed. The ignition reference signal at this time is inputted every time the crankshaft axis 13 is rotated. Please refer to Figure 5 (e), the engine starts to reverse from the stop position Pa in Figure 5, and the ignition reference signal is input from the start of the intake stroke to the exhaust stroke. When the ignition reference signal is obtained in step S4, the process proceeds to step S5. Use the absolute position of the piston to identify and correct the absolute angle of the crankshaft axis. At this time, the rotation control of the engine 10 is obtained by using the rectified position pulse signal shown in FIG. Figure 8 illustrates the relationship between the rectified position pulse signal and the ignition reference signal. Please refer to FIG. 8, the engine 10 is divided into three positions, and a rectification position detection detector 25 is provided to detect the input of the three-phase rectification detection signals U, V, and W. That is, each signal is captured at the beginning to form a rectified position pulse signal with a predetermined period. At this time, the ignition reference signal is input when the impedance 40 passes through the pulse coil 41, and the obtained crank angle is always maintained constant (before the upper end point). The rectified position pulse signal is obtained at a predetermined crank angle interval. Next, after the ignition reference signal is obtained, input the rectified position pulse signal into the calculator, and then distinguish according to the rotation angle starting from the set crankshaft angle. The correct paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the notes on the back before filling out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. ·· -------- Order _________ Line — ·! 1 !!: ί ______ 479106 A7 B7 6951pif.doc / 008 V. Description of the invention ((¾) Grasp the current crankshaft angle. After grasping the absolute angle of the crankshaft axis, proceed to step S6, and use the crankshaft angle controller to determine whether the piston has reached the explosion stroke. In the intermediate position, when it is recognized that the intermediate position of the burst stroke is reached, step S7 is performed to stop the reverse power. On the other hand, if the intermediate position of the burst stroke is not reached, step S8 is performed to determine whether the piston has reached the reverse compression state. That is, before the crankshaft axis reaches the intermediate position of the burst stroke during the reversal, it is judged whether there is a state of receiving a compressive load. At this time, the reverse compression state of step S8 The judgment is made by capturing the amount of change in the crankshaft angle. The cycle of detecting the rectified position pulse signal is obtained by comparing the number obtained this time with the number obtained last time. When the difference is within the predetermined number At this time, it is judged that the piston is affected by the compression force to reduce the amount of change in the crankshaft angle, and then it is determined to be the reverse compression state. Then it can be compared with the number calculated using the cycle speed, and it can also be compared with the acceleration change obtained using the predetermined value. Compare. However, the determination method using the suspected acceleration change in the foregoing cycle has the advantage of reducing the load on the CPU 32. In the case where the reverse compression state is detected in step S8, step S7 is performed to stop the reverse power supply. Otherwise, When no reverse compression is checked, step S9 is performed to determine whether the set maximum reversal time has passed. When the maximum reversal time has passed, step S7 is performed to stop the reversal power without the maximum reversal. The time returns to step S6 to perform the aforementioned operation sequence. When the reverse rotation is stopped in step S7, the crankshaft axis 13 will have an inertia.

Description of the invention (Η) The rotation is then switched to the forward rotation drive. The control system of the present invention uses an absolute angle • The three conditions of operation and time are (1) the rotation of the crankshaft axis at the reverse rotation allowable position (before compression to the upper end point), (2) the start of forward rotation, and (3) the switching between stopping the energization after a predetermined time, etc. Judge. The identification of the absolute angle of the crankshaft center in step S5 'will affect the determination of whether the maximum allowable position of the crankshaft angle reversal (reversal allowable position) is reached in step S10. That is, when the reverse rotation allowable position is reached (Qa shown in Fig. 5 (c)), step S11 is performed, and the crankshaft axis 13 starts a normal forward rotation operation. The allowable reverse position can be adjusted based on engine temperature (water temperature, air temperature, unit temperature, or engine temperature) or battery voltage status. That is, based on the engine temperature or battery voltage, the judgment of the most suitable reversal allowable position that exceeds the torque is set to start in a relatively short time. For example, when the engine is restarted after stopping, high battery voltage and high engine temperature are used as starting conditions to return to the exhaust stroke. When the battery voltage is low or the engine is not warmed up, the forward rotation will return to the burst stroke. In addition, when the voltage is low or the engine temperature is low, the compression reaction force of the burst stroke can be used to forward rotation. And in the case of low voltage or low temperature of the engine, the reaction force of the reverse compression stroke used in the forward rotation is activated by the reaction force of the compression stroke. Furthermore, the main purpose of the warning light is to let the operator know that the starting action must meet the predicted conditions, and the starting action will act on its own. In step S10, if it is recognized that the reverse rotation allowable position has not been reached, step S12 is performed to determine whether the crankshaft axis 13 is in a forward rotation state. That is to say, it is determined that the Chinese paper standard (CNS) A4 (210 X 297 mm) is applied to the 22 paper sizes (Please read the precautions on the back before filling this page) Printed by the Intellectual Property Bureau Staff Consumer Cooperative of the Ministry of Economic Affairs I Γ k I -r— IIIIII · 111-I —-IIIIII J- III-I-I--I ------ A7 B7 Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 479106 6 9 5 lp if. doc / 0 0 8 V. Description of the invention () u) Whether the compression force before the allowable position starts to rotate forward. If the forward rotation has been started, step S11 is performed to start the forward rotation operation. If no forward rotation is detected in step S12, then step S13 is performed to determine whether or not the predetermined time for stopping power (for example, 100ms) has passed. That is, the predetermined maximum value is set to the inert rotation time after reversal. At time, and before reaching the forward rotation allowable position, step S11 is performed to start forward rotation. Conversely, if the situation before the power-on stop time has elapsed, return to step 10 'to return to the aforementioned operation sequence. The starting control of the present invention uses the ignition reference signal and the rectified position pulse signal to determine the correct crank angle. In particular, a crankshaft angle is detected by a separately provided detector, and the reverse rotation control is surely performed based on the absolute angle of the crankshaft axis. In addition, by setting the maximum time to reverse the power-on time or power-off time to prevent the start-up hysteresis that occurs when the reversal at start-up exceeds a predetermined time. On the other hand, when the engine is stopped, the piston will not be near the end point of the compression stroke. For example, when the Pb position in Fig. 5 (c) is stopped near the stopping point below the exhaust stroke, the ignition reference signal is not obtained. That is, in the case where the ignition reference signal is not obtained in step S4, the aforementioned absolute angle cannot be controlled. The above points are not without mentioning too much about this situation. The control device determines the right turn timing in the aforementioned determination of the suspected acceleration change. When the ignition reference signal is not obtained in step S4, step S14 in FIG. 7 is performed to determine whether there is the reverse compression state similar to that in step S8. When it is detected that there is no reverse compression, go to step S16 to judge 23 this paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) (Please read the precautions on the back before filling this page)

Description of the invention p 1) Determine whether the set maximum reversal time has passed. When the maximum reversal time has elapsed, step S15 is performed to stop the reverse power supply. If the maximum reversal time has not elapsed, the process returns to step S4 to perform the above-mentioned sequence. In step S15, the power supply is stopped, and at the same time, the crankshaft axis 13 performs inertia rotation. Next, step S17 is performed to determine whether the crankshaft axis 13 is in the forward rotation state. That is, it is determined whether the return compression force of the piston and the crankshaft axis 13 start to rotate forward. When the forward rotation is started, step S18 is performed to start the forward rotation operation. If the forward rotation is not checked in step S17, step S19 is performed to determine whether the predetermined power-off time has passed. When the power-off time has elapsed, before the forward rotation is checked, step S18 is performed to start the forward rotation. On the other hand, if the power-off time has not elapsed, the process returns to step S17 and repeats the foregoing sequence. This action makes the engine 10 start to rotate forward. At this time, the crankshaft axis 13 rotates under the low load of the exhaust stroke and the intake stroke. Before the piston 10 enters the compression stroke, the engine 10 has reached the maximum number of rotations under almost no-load rotations. Then, the crankshaft axis 13 has reached the maximum possible number of rotations of the engine 10 before the compression stroke is performed. This rotation system enters the compression stroke in a state where the inertial mass accumulates the inertia energy to the maximum. In the compression stroke shown in FIG. 4 (b), the crankshaft axis 13 is rotated using a synthetic energy (thick solid line) synthesized by inertia and energy (a dotted line) and engine energy (solid line). In addition, the driving energy of the engine 10 shown in Fig. 4 (b) is provided by using the crankshaft axis 13 more than two times to drive. Then, the compression stroke load that can be supplied by one energy exceeds the energy that a conventional engine can supply, so the engine energy can be increased. 2 This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) ( Please read the precautions on the back before filling this page); ________Order ______ line — • i — Ji i — li! 479106 A7 B7 6951pif.doc / 008 i. Description of the invention () 1) Efficient use . After the initial compression stroke has been exceeded, the inertial energy accumulation has been followed by the compression stroke which can easily exceed the load. In this way, the engine can be started by using the appropriate ignition line 圏 35 to generate splash sparks. In this way, the engine 10 of the present invention drives the piston once when the engine starts, and then returns to the burst stroke to start the engine. Then, after the first compression stroke, the inertial energy held by the crankshaft axis 13 will become higher and higher. That is, the interval of the crankshaft axis 13 to assist in walking is set. This interval can be used to accumulate energy, and a torque smaller than the conventionally used engine torque can be used to exceed the first compression stroke. In this way, the engine can be miniaturized or painted at low cost, and the power consumed by the generator can be reduced. In addition, when the piston returns to the burst stroke, the absolute position of the piston (the absolute angle of the crankshaft axis) can be grasped using the ignition reference signal and the rectified position pulse signal, and based on this, the engine 10 is controlled to stop the reverse rotation or a moderate positive turn. Therefore, there is no need to use other detectors such as cam angle detector or crank angle detector, and only the existing detector can be used to correctly control the reverse rotation-forward rotation. In addition, based on the absolute angle, the reverse rotation and forward rotation of the crankshaft axis can be controlled accurately and moderately, and an inertia starting control method with good efficiency can be obtained. This starting operation starts from the ignition exceeding the compression stroke, and when stopping afterwards, the absolute angle obtained is used as the basis to control the reverse rotation and forward rotation of the engine 10 at the next start. This can prevent the engine 10 from failing to start, and can start with better efficiency. Also, stop idling while waiting for the signal, stop the engine starting when the vehicle starts. 25 This paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 public love) (Please read the precautions on the back before filling this page) Ministry of Economy Printed by the Intellectual Property Bureau employee consumer cooperative i #________ t ____! _____ ^ — φ ____ · ί ._____!

Description of the Invention ) Or start, and in the process from engine stop to restart, the absolute angle can be identified in less than the number of rotations set by the engine, and when the engine is started, the absolute angle at stop is used as a reference Perform reverse and forward motions to start with better efficiency. As described above, the engine can be controlled to start by obtaining a rotation pulse including a starting rectification pulse or a direct crankshaft rotation signal, an ignition reference signal, and an absolute angle. (Second preferred embodiment) The next second preferred embodiment is to perform a preliminary forward operation before the reverse operation at the start of the first preferred embodiment, in order to reliably obtain the control pattern of the absolute angle. Be explained. In the case where the control mode of the first preferred embodiment is that the aforementioned piston is stopped at the Pb position in FIG. 5, an appropriate reverse-forward rotation setting is set by the determination of the suspected acceleration change in FIG. 7, To get the ignition reference signal. However, when the output position of the ignition reference signal is at 1 degree without stopping at the Pb position, the absolute angle of the crank shaft axis cannot be controlled by the ignition reference signal. Therefore, in the second preferred embodiment, the pre-reverse rotation is performed to the extent that the driving force of the compression stroke does not exceed the driving force of the compression stroke before the reverse operation of the first preferred embodiment, that is, once the piston in the suction stroke is in the direction of the compression stroke No matter where the piston is stopped, the piston can output the ignition reference signal until the reverse rotation is performed. Figure 9 shows a schematic diagram of the starting principle of the second preferred embodiment of the present invention: (a) starting load of each stroke '(b) starting energy, (c) piston position during starting operation, (d) rectification Pulse signal from the position detector, (e) 2 6 This paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) • ϋ H ϋ ϋ ϋ ϋ ϋ I ϋ I ϋ ϋ ϋ ϋ ^ 1 n I ϋ ϋ 1 1 ϋ H ϋ .1 II ϋ ϋ I n ϋ I ϋ n ϋ ϋ nn IIIIH ϋ I n I (Please read the notes on the back before filling this page) 479106 A7 B7 6951pif.doc / 008 V. Description of the invention (Represents the ignition reference signal. Figure 10 shows the flow chart of the control sequence. Please refer to Figure 10. In this embodiment, when the CPU 32 is in step S20, the ignition switch 39 is turned on as usual. In step S21, it is determined whether to start the start switch 34. After the start switch 34 is turned on, the process proceeds to step S22, and the engine performs a forward rotation process as soon as the engine rotates forward. Figure 11 shows a flowchart of the sequence of the preliminary forward rotation process The forward rotation process starts from Pb in Fig. 5 to the stop position on the compression stroke side. The engine prepares a forward rotation by Pa. The aforementioned pseudo acceleration change determination is used to determine the optimal reverse rotation switching. That is, the engine 10 performs a preliminary forward rotation in step S41. In this case, the forward rotation operation is performed by the piston. All driving forces starting near the end point below the exhaust stroke to move near the end point below the compression stroke, and the engine 10 outputs a rotation that is lower than the normal forward start. Then, step S42 is performed to determine whether the piston is compressing in the forward direction. In the state, that is, when the crankshaft axis is ready to rotate forward, it is judged whether the piston enters the compression stroke under a compression load state. The determination of the forward rotation compression state in step S42 is determined by using the aforementioned suspected acceleration change. When a positive check is detected in step S42 In the case of the compression state, step S43 is performed to stop the forward rotation. Otherwise, if the condition of the forward compression state is not checked, step S44 is performed to determine whether the set maximum pre-forward time has passed. When the maximum pre-forward time has elapsed Step S43 to stop the forward rotation, if it has not passed, return to step S42 before repeating After stopping the forward power supply in step S43, leave the paper according to the rules. 27 27 This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (Please read the precautions on the back before filling out (This page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs!

Description of the invention (〇 ( Please read the precautions on the back before filling this page), and perform the reverse operation of step S23 in Figure 10. This is the reverse rotation of the crankshaft axis 13 to obtain the ignition reference signal in step S24. At this time, at the start of the reverse operation in step S23, the piston system exists near the end point under the suction stroke in the compression stroke, thereby driving toward the burst stroke side, and the ignition will inevitably pass near the end point on the exhaust stroke. Reference signal occurrence position. That is, even if the piston is stopped at the position of Pb, once the piston moves to the compression stroke side, it will inevitably pass the ignition reference signal generation position. Therefore, in step S24, the ignition reference signal can be reliably obtained, and thereafter, the crank reference angle can be accurately grasped by using the ignition reference signal and the rectified position pulse signal. After obtaining the ignition reference signal, step S25 is performed to identify and correct the absolute angle of the crankshaft axis using the absolute position of the piston. Thereafter, using this absolute angle as a basis, the reverse rotation-forward rotation control of steps S26 to S33 is performed. Since the control of steps S26 to S33 is the same as steps S6 to S13 in the first preferred embodiment, detailed description is omitted here. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs before performing the reverse operation in this embodiment, a preliminary forward operation will be performed first, so that the ignition reference signal generation position will surely be obtained during the reverse operation, and it will be reliably obtained Ignition reference signal to accurately identify and control the absolute angle of the crankshaft axis. Since it is stopped at the Pb point, it is close to the ignition reference signal generation position and burst stroke, so the secondary ignition reference signal can be obtained for the control of any absolute angle. When the reference signal is obtained, it is preferable to directly stop the power supply for the forward rotation and perform the reverse rotation.

In the engine 10, the ignition reference signal is constituted by outputting the crankshaft center 13 every time it rotates. In the case where the two-stroke engine has only one revolution and one ignition, it cannot be controlled by using the reference signal of the inertia start-up assisted walking zone. In a two-stroke engine, the aforementioned ignition reference signal is added, and an additional second impedance is used to provide a signal that occurs during the inertial start assist. A reference signal (a second reference signal) obtained by identifying the crank angle is used to implement the control mode of the present invention. At this time, the additional impedance 'is set at the reference signal output position between the time when the mixed gas is inhaled and the end point below the start of the exhaust gas is not reached. This ignition signal does not affect the combustion behavior of the engine. Add an appropriate impedance at a position other than the above, and the reference signal output at this time must be processed to prohibit ignition. In addition, precise ignition control can be performed by arranging multiple impedances, and appropriate control can be performed based on signals generated by the impedances. On the other hand, it is more appropriate to use an additional pulse coil instead of the additional impedance. That is, the pulse line 圏 41 'shown in the first figure is added, and a second pulse coil is provided at the position of the non-compressed stroke (about 90 degrees to 270 degrees of BTDC) to output two reference signals when the crankshaft axis rotates once. . The two pulse wires 2 are preferably made of the same material. In this way, similar to the normal pulse coil 41, the signal of the additional pulse coil can also be used for ignition. Ignition near the end point under the burst stroke does not interfere with the combustion action 'and does not affect the ignition energy. It also uses the recognition result of the absolute position as a basis to make a better judgment on the lower end point side.

Description of the invention (ο) The polarity (order of voltage change) of the added pulse coil is two different signals from the official pulse line 圏 41, so that the CPU 32 can easily determine. Therefore, it is possible to suppress the ignition operation other than the official ignition position, prevent ignition that is harmful to the combustion operation, and save the cost of shared energy. (Fourth preferred embodiment) Next, a fourth preferred embodiment will be described in a case where the crank angle detecting device is suitable for use in a start-up engine in an engine (internal combustion engine). Here, the same materials as those of the first preferred embodiment are used, and therefore the descriptions using the same symbols are omitted. The starting engine of the fourth preferred embodiment is constituted by the same method as in Figs. 1 to 3, so the description of Figs. 1 to 3 is omitted. The CPU 32 is provided with the following functional devices. Fig. 13 is an explanatory diagram showing a related functional constitution device suitable for utilizing the CPU 32 as a crank angle detecting process according to the present invention. The CPU 32 is an ignition reference signal acquisition device 51 for calculating the absolute angle of the crankshaft shaft center based on the ignition reference signal and the angle pulse, and the ignition reference signal of the engine is obtained by using the pulse coil 41, and the detection is performed by using the rectified position. The generator 25 obtains an angle pulse forming device 152 for detecting a rectified position detection detection signal (rectified position signal) for controlling the engine 10 to form an angle pulse described later, and calculates the absolute value of the crankshaft axis 13 based on the ignition reference signal and the angle pulse. The crank angle calculation device 153 and the absolute angle of the crank shaft center 13 calculated by the crank angle calculation device 153 are configured as an engine control instruction device 154 for controlling the engine 10 based on the absolute angle. 30 This paper size is applicable to China National Standard (CNS) A4 (210 X 297 cm) (Please read the precautions on the back before filling this page)

Description of invention d) On the other hand, the rotation control of engine 10 is detected by the rectified position shown in Figure 14. Measurement signal. Figure 14 illustrates the relationship between the detection signal for the rectified position detection, the angular pulse formed by detecting the detection signal with the rectified position, and the ignition reference signal. Referring to Fig. 14, the engine 10 is divided into three positions, and a rectifying position detection detector 25 is provided to detect the input of three-phase rectifying position detection signals U, V, and W. That is, each signal is captured to form an angular pulse with a predetermined period. Fig. 14 shows a state where the three-phase rectified position detection detection signals U, V, and W are used to form an angle pulse at intervals of 20 degrees based on the edges. At this time, the ignition reference signal is input when the impedance 40 passes through the pulse line 圏 41, and the obtained crank angle is always maintained constant (before the upper end point). That is, the crank angle of the ignition reference signal output is 0. Often remain constant. In addition, an angular pulse is formed at a certain crank angle interval (20 degrees in FIG. 14). Then, the crank angle 0 is obtained by using the ignition reference signal. After that, the angle pulse is input into the calculator, and then distinguished according to the crank angle (the rotation angle starting from 90) to grasp the current crank angle. Then, without adding the impedance 40, the crank angle can be grasped by using one impedance. When multiple impedances are provided In this case, the same impedance is used for control, and the number of labor required to increase the impedance may reduce the cost. Since no other detectors such as a cam angle detector or a crank angle detector are needed, only Need to use the existing detector to accurately grasp the crank angle, so it can suppress the increase in production costs.

Using the read-only memory 37 that summarizes various control programs, it can perform engine start control and moderate fuel injection control. Various energy controls such as fuel injection amount control, etc. The accuracy of crankshaft angle detection can be distinguished from Fig. 14, and the period change of the angle pulse can be appropriately changed. Fig. 15 and Fig. 16 are based on the angle pulse interval. An explanatory diagram of the relationship between the angle pulse and the ignition reference signal in the case of 60 degrees and 10 degrees. In Figure 15, the rectified position detection detection signal is expressed by the first phase division (U phase), As a result, an angle pulse starts to form, and the interval is longer than the interval shown in Fig. 14. Therefore, in the case of Fig. 15, the detection accuracy of the crank angle itself will not be much lower than that in the case of Fig. 14. But it can be This reduces the burden on the CPU 32, which is very effective in general engine control that does not require strict control. In contrast, in the case of Figure 16, the three-phase signal formation from the rectified position detection detector 25 is performed from the beginning to the end. The angle pulses used on both sides are shorter than the interval shown in Figure 14. Therefore, the accuracy is higher than that of the crank angle detected in the case of Figure 15. High-performance engine under strict control. Figure 16 shows the case where the rectified position detection detector 25 is used with the entire integrated circuit of the unipolar detection type. At this time, the entire product of the unipolar detection type is used. The high power ratio of the body circuit is greater than 50%. The narrow and wide pulse intervals interact to form the two sides of the starting edge and the ending edge of the angle pulse. At this time, the period measurement of the angle pulse is an even number The average of the cycle (for example, 2 cycles).

However, when the rectified position detection detector 25 is used with the entire integrated circuit of the bipolar detection type, the power ratio of the entire integrated circuit of the bipolar detection type may be slightly lower. In addition, the rectified position detection detection signal uses the CPU 32 to appropriately process the angle pulse forming device 52 to optimize the angle pulse. In Figure 17 (a), in order to improve the control accuracy, the angular rectification can be used to obtain the physical rectified position to detect the change point of the detection signal. For example, where there is no physical signal, the angle pulse can be used to form . In Fig. 17 (a), a 10-degree interval formed on both sides of the start edge and the end edge is used, and then the angular pulse is used to form an angular pulse with a 5-degree interval. In this way, angle pulses will be formed at the positions where the angle pulses at the original 10 degree interval do not exist. The number of rectified position detection detectors 25 need not be changed, that is, the detection accuracy corresponding to the software of the circuit can be made. rise. On the other hand, one pulse is divided into several cycles, which can form angle pulses at 15-degree intervals as shown in Figure 17 (b). In this way, in the original position where the angle pulses at 10-degree intervals do not exist Angular pulses are formed. Furthermore, the shorter the interval (period) of the angle pulses in the high rotation area of the engine, it may cause the calculation processing capacity of the CPU 32 to be exceeded. The software that forms the physical angle pulse loop in Figure 17 (c) can moderate the pulse interval. In this way, when the predetermined rotation is exceeded, a phase of the detection signal can be detected by using the rectified position to control switching to the corresponding signal.

Furthermore, although the present invention has been described as being applied to a four-stroke engine, the present invention is not limited to a four-stroke engine and may be applied to a two-stroke engine. Although the internal combustion engine starting control device of the present invention uses the ignition reference signal and the rectified position pulse signal as the basis to obtain the absolute angle of the crankshaft axis, and then uses this absolute angle as the basis to control the start of the engine, it can also directly use the ignition reference signal and the rectified position. Existing signals such as pulse signals are used to start the engine. Therefore, the crank angle detector and the like do not need to be separately attached, that is, they can use the absolute angle of the crankshaft axis as the basis to perform correct start control for efficient engine starting. In addition, based on the absolute angle of the crankshaft axis once reversed, and based on the normal rotation of the internal combustion engine, the crankshaft axis can be properly reversed, and the forward rotation can be accurately controlled. Therefore, it is possible to perform high-efficiency inertial start control without performing useless start control. In addition, before the start of reverse rotation, the crankshaft axis can also be properly prepared for forward rotation. In this way, the crankshaft axis will definitely pass the ignition reference signal generation position during reverse rotation, and the ignition reference signal can be reliably obtained. In addition, at least one of the battery voltage and the engine temperature is used as the basis. The amount of crankshaft axis reversal is adjusted. In this way, the battery or the engine state is used to properly start the control to shorten the start time.

The absolute angle calculation device for the absolute angle of the invention description (M), and the engine that starts the engine based on the absolute angle control Control indicating device. It is also possible to control the starting of the engine based on the absolute angle of the crankshaft axis using existing signals such as the ignition reference signal or the rectified position pulse signal. Therefore, there is no need to attach a crank angle detector, etc., that is, accurate starting control can be performed based on the absolute angle of the crankshaft axis to perform efficient engine starting. In addition, the start-up control device is provided with a battery voltage detection device and an engine temperature detection device. The engine control instruction device may also control the start-up engine based on at least one of the battery voltage and the engine temperature. In this way, moderate start-up control based on the state of the battery or engine can shorten the start-up time. In addition, the crank angle detecting device of the present invention detects the absolute angle of the crankshaft axis using an electrical signal obtained by a pulse coil or a rectified position detection detection signal. Therefore, no additional impedance or crank angle detector is needed to grasp the absolute angle of the crankshaft axis. Therefore, it will not increase the number of processing workers or parts, and use the crankshaft angle as the basis for engine control. It will not increase the cost, and it will not be impossible to apply it to high-performance engine control. As mentioned above, the absolute angle of the crankshaft axis is detected using the reference pulse and the rectified pulse started by ACG. Therefore, it is possible to accurately perform the measurement without adding an impedance (except for the ignition reference) or a crank angle detector.
