Definitions
- the invention relates to a device for determining the position of an internal combustion engine comprising a rotary member. More specifically, the invention aims to improve the starting of internal combustion engines with several cylinders in order to reduce the starting time of these engines, or even to allow direct starting of the engine without starter, by better knowledge of the position of each piston. to select the cylinders to be supplied with fuel.
- engine control means calculate the quantity of fuel to be injected, the moment when it must be injected into each cylinder and the moment when the ignition must be ordered. To do this, the position of the motor must be precisely determined.
- EP-A-0 017 933 describes a device comprising contactless sensors of the incremental type mounted on a crankshaft and on a camshaft of an internal combustion engine. These sensors each include a disc, the surface of which has regularly arranged marks (angularly offset by an increment) and reference marks. Probes detect the passage of successive marks relating to an incremental rotation of the crankshaft and camshaft and the reference marks. However, after switching off the engine, the position of the engine is no longer known, so it is necessary to carry out a synchronization procedure comprising at least one rotation of the engine crankshaft. On the other hand, devices are known comprising an absolute type contactless sensor.
- DE-A-197 22 016 describes a device comprising a sensor of this type comprising a Hall effect type probe and a magneto-resistive type probe arranged at the end of the camshaft and subjected to a rotating magnetic field with the shaft with cams.
- a device of this type does not make it possible to know precisely the position of the crankshaft insofar as on the one hand there is a play in the mechanism connecting the camshaft and the crankshaft and where on the other hand the camshaft and the crankshaft can find themselves angularly offset with respect to each other for engines fitted with a device for varying the time and the opening amplitude of the valves.
- the invention therefore aims to provide a device of moderate cost solving the aforementioned problems and in particular allowing to know precisely the position of the crankshaft at any time including after a prolonged stop of the engine.
- the device comprises: - an incremental type sensor comprising a rotary part linked to the rotary member and a fixed part comprising: • from the first means for detecting a reference position of the member rotary and detecting the rotation of an increment between the mobile part and the fixed part, said first means generating a first signal, • second means for detecting the direction of rotation between the mobile part and the fixed part generating a second signal, • analysis means connected to the first means and to the second means for determining the angular position of the rotary member with respect to the reference position, from the first signal and the second signal, and generating a third signal which is a function of said position angle of the rotary member, - engine control means connected to the sensor analysis means, said engine control means comprising a idle state in which they are not electrically supplied and a live operating state during which they generate actions on engine operating members, such as fuel injectors or spark plugs, according to the third signal , in which device the sensor is electrically powered permanently, including when the control means are in
- the sensor comprises: - an economical mode of operation comprising successively and at regular intervals an activity phase during which the first means and the second means are supplied with electricity and a phase of inactivity during which the first means and the second means are not supplied with electricity and - a normal operating mode during which the first means and the second means are supplied electrically continuously.
- the rotation of the motor is supposed to be reduced when the sensor is in economic operating mode than when the sensor is in normal operating mode, the motor control means being advantageously not electrically supplied when the sensor is in operating mode. economical operation.
- the first means and the second means can therefore operate intermittently to consume less electricity without losing their ability to move the engine.
- the duration of the inactivity phases is at least 10 times longer. long that the duration of the activity phases and the duration of an activity phase added to that of a consecutive inactivity phase is less than 1 second.
- the analysis means generate the third signal only after reception of a fourth signal emitted by the engine control means. Thus, the work of the analysis means and their electrical consumption are reduced to a minimum.
- the analysis means transmit to the engine control means a signal corresponding to the first signal.
- the engine control means can know the displacement of the engine relative to the position transmitted by the third signal and thus deduce the position of the engine in real time.
- the device has the following characteristics: - the first signal comprises at least two levels, - the sensor further comprises a counter incremented or decremented at each change of level of the first signal according to the direction of rotation detected by the second means, and - the counter is reset to zero after detection by the first means of the reference position of the rotary member.
- the internal combustion engine comprises a crankshaft
- the rotary member is constituted by the crankshaft of the engine
- the counter is reset only once every second after detection by the first means from the reference position of the rotary member.
- the position of the crankshaft is known over 720 °, therefore the position of the engine is perfectly known.
- the device has the following characteristics: - the internal combustion engine comprises a crankshaft and a camshaft, - the rotary member consists of the crankshaft of the engine, the device also comprises an angular position sensor placed on the camshaft generating a binary signal.
- FIG. 1 is a schematic representation of a device according to the invention, comprising in particular a sensor and a motor control
- - Figure 2 is a detailed view of the fixed part of the sensor belonging to the device shown in Figure 1
- - Figure 3 represents the current consumption of the sensor
- - Figure 4 represents signals transmitted by the sensor to the engine control unit
- - Figure 5 illustrates an alternative embodiment of the device of Figure 1.
- Figure 1 illustrates a device 1 essentially comprising a sensor 2 and a motor control unit 4.
- the sensor 2 is connected to the engine control unit 4 by a single wire 48.
- the engine control unit 4 is connected to engine operating members, such as spark plugs 50 and injectors 52.
- the sensor 2 comprises a rotary part 8 secured to an engine crankshaft and a fixed part 6 intended to raise the displacements of the rotary part 8 and shown more precisely in FIG. 2.
- the rotary part consists of a disc 8 consisting of a succession of 60 teeth and 60 recesses uniformly distributed, so that the teeth (respectively the recesses) are arranged periphery of the disc every 6 degrees, which corresponds to an increment of displacement of the crankshaft.
- the fixed part 6 comprises an assembly 10 for detecting the displacement of the rotary part 8, an analysis unit 12 and a memory 14.
- the analysis unit 12 integrates means for processing analog signals, a microprocessor, a program analysis, internal counter and clock.
- the assembly 10 for detecting the displacement of the rotary part 8 comprises a magnet 16, three probes 18, 20, 22 and a signal conditioning assembly 26.
- the magnet 16 generates a magnetic field which is modified by the presence of the teeth of the disc 8, so that the voltage detected by the probes 18, 20, 22, here of the Hall effect type, is a function of the presence or not of a tooth facing the probe.
- the probes 18 and 20 are offset by a distance less than the width of a tooth.
- the voltages from the probes 18 and 20 are entered in a first part of the signal conditioning circuit 26, which transmits to the analysis unit 12 a first signal 28 having a first value when the probes 18, 20 are opposite 'a tooth and a second value when the probes 18, 20 are opposite a hollow.
- the analog signal processing means, the microprocessor and the analysis program of the analysis unit 12 process the signal 28 and detect the passage of the signal 28 from the first value to the second value corresponding to a rotation of one crankshaft increment.
- the processing of the first signal 28 by the analysis unit 12 makes it possible to detect the reference position 24.
- the probe 22 is offset by a distance less than the width of a tooth relative to the probe - 20.
- the voltages from the probes 20 and 22 have entered a second part of the signal conditioning assembly 26, which transmits to the analysis unit 12 a second signal 30 having a first value when the probes 20, 22 are opposite a tooth and a second value when the probes 20, 22 are opposite a hollow.
- the analysis program and the processor of the analysis unit 12 process the signals 28, 30 and determine the direction of rotation of the crankshaft. Depending on the direction of rotation determined, the analysis unit 12 increments or decrements the internal counter in accordance with the displacement of the crankshaft by an increment.
- the internal counter When the internal counter reaches a value corresponding substantially to two turns of the crankshaft, the internal counter is brought back to a determined initial value (advantageously zero) when the reference position 24 is detected. Thus, if an error occurs during a count, it is corrected by the detection of the reference position 24 and does not influence the following count.
- the power supply to the engine control unit 4 is cut off when the user of the vehicle on which the device is mounted switches off the ignition 32, on the other hand the sensor 2 is permanently supplied with current from the vehicle battery 34. More specifically, the analysis unit 12 is permanently supplied by the vehicle battery and manages the electrical supply 36, 37 of the assembly 10 for detecting the movement of the rotary part 8 and of the memory 14.
- the engine control unit 4 When the engine is in operation, the engine control unit 4 is electrically powered, as is the assembly 10 for detecting the displacement of the rotary part 8 and the memory 14. On the other hand, when the engine control unit 4 does not is no longer electrically powered, the engine stops and after a determined period during which no rotation of the engine is detected from the signal 28, the analysis unit 12 stores the value of the internal counter in the memory 14, then places the sensor in an economical mode of operation 38. As illustrated in FIG. 3, in the economical mode of operation 38 of sensor 2, the assembly 10 for detecting the displacement of the rotary part 8 is periodically electrically supplied for a time t advantageously here of approximately 100 ⁇ s, then not supplied for a time T advantageously here approximately 10 ms.
- the analysis unit 12 If the analysis unit 12 does not detect any rotation of the crankshaft from the first signal 28, the economic mode of operation is continued. On the other hand, if a displacement of the crankshaft is detected, the analysis unit 12 places the sensor 2 in normal operating mode 40, the assembly 10 for detecting the displacement of the rotary part 8 and the memory 14 then being supplied with electricity. permanently, the value of the memory 14 is read, modified according to the movement detected and transmitted to the internal counter. The analysis unit again places the sensor 2 in economic operating mode after the determined period during which no rotation of the crankshaft is detected from the first signal 28.
- the analysis unit 12 When the analysis unit 12 receives a determined signal of the engine control unit 4, advantageously just before starting the engine, the analysis unit 12 transmits for a short instant 42 the value 46 of the internal counter, here framed by two parity bits, to the unit 4 of engine control. In order to count the 116 positions of the discs (58 teeth on two turns), the counter here has 7 bits-.
- the analysis unit 12 transmits to the engine control unit 4 a square signal 54 (alternately having two values) corresponding substantially to signal 28 or to signal 30 received from the packaging assembly. of the signal 26, each falling edge of the square signal 54 representing an increment of displacement of the crankshaft detected by the assembly 10 for detecting the displacement of the rotary part 8.
- the engine control unit 4 thus always knows precisely the position of the front engine to act on the operating members of said engine. If the analysis unit 12 detects a power cut, when it receives the determined signal from unit 4, instead of transmitting the value of the counter, it transmits a signal defined for this purpose (by for example the value 116 or the value 127 in binary) to the engine control unit 4, in order to carry out a preliminary initialization procedure.
- the memory 14 is of the read only memory type so as not to consume current when the sensor is in economic operating mode. One could however also provide a memory type RAM low consumption that would be supplied electrically permanently.
- FIG. 5 illustrates a device 101. This device 101 differs from the device 1 shown in FIGS.
- the angular position sensor 156 is connected to the engine control unit 4.
- the movable part 158 having a half-moon shape, the angular position sensor 156 generates a binary signal 162 having a first value when the camshaft occupies a position between 0 ° and 180 ° and a second value when the camshaft occupies a position between 180 ° and 360 °.
- the engine control unit 4 receives a signal the position of the engine on 720 ° of the crankshaft.
- the internal counter is therefore reset (for example reset to zero) each time it passes through the reference position.
