Angular displacement when to the effect that adopting Hall element non-contactly the transaxle pedal to be moved of the present utility model is converted to the voltage signal output of 0.5V～4.5V, to satisfy the required EFI control signal voltage of car engine control module (ECU).It comprises the following content:
The actuating range of transaxle pedal is about about 0 °～19 °, and in order to increase the dynamic range that is converted to rotating magnetic field, the way by machinery can expand 0 °～19 ° angular displacement to about 0 °～60 ° anglec of rotation.
The angle rotation of this amplification drives a rectangular permanent-magnet steel around its rectangular central shaft rotation by rotor 9, to produce vertical this central shaft plane with a left side, the magnetic field of right rotation.
In the rotating range on this rotating magnetic field plane, determine a centre position, parallel plane therewith two magnetic field induction iron plates (being magnetic conductor 10,11) up and down are set, this rotating magnetic field can transfer the magnetic field of vertical direction to, and this induced field will change size and positive-negative polarity along with the rotation of permanent-magnet steel.
Use Hall element that this is rotated the magnetic field intensity that changes size and Orientation with permanent-magnet steel and change voltage signal output into.If selected change of magnetic field strength scope drops on the linear work district of Hall element, then the voltage signal of being changed will be linear with the angle of rotating magnetic field.
The output signal of Hall element is through the discharge circuit amplification and consider the adjustment of putting in addition with full scale value, can produce the output voltage signal that satisfies engine control unit (ECU) EFI input request signal.
Amplifying circuit must satisfy low-power consumption, the requirement of great dynamic range and anti-power supply undesired signal.The making of circuit board also need be satisfied the requirement that is installed in the limited bulk extremely simultaneously.
Because ECU (engine control unit) requires accelerator pedal when action two independent but identical voltage signal of signal simultaneously, the utility model can realize allowing a rotating magnetic field produce the function of two vertical magnetic fields simultaneously, use two independently Hall element and signal amplification and treatment circuits, to satisfy the requirement of ECU.
Utilize the analog voltage signal of being exported, whether the switching signal that can produce-be exported by optocoupler by a comparator circuit has the generation of action to indicate accelerator pedal, and this switching signal can be used for the operating state of ECU judgement pedal.The load capacity of switching signal is the load that can load 28V voltage, can drive R=6.8K Ω and C=2 * 4.7nF, maximum load current ability 10Ma, complete alternative old-fashioned Mechanical Contact formula limit switch, the serviceable life of improving position switch greatly.

Fig. 4 is signals collecting converting means 6 part decomposition texture synoptic diagram.The action of pedal 1 drives throttle axle 5 and rotates, and has enlarged the slewing area of angular displacement range by physical construction, to adapt to the variation of using Hall element to detect magnetic field non-contactly.The rotation of throttle axle 5 has driven the rotation of rotor 9 again.The afterbody of rotor 9 is equipped with permanent-magnet steel 12, and along with the rotation of rotor 9 and permanent-magnet steel 12, the angle of rotation will be converted to rotating magnetic field. Magnetic conductor 10,11 in the outside of permanent-magnet steel 12 will go out the vertical magnetic field relevant with the anglec of rotation along with the rotation of permanent-magnet steel 12 is sensed, and this will convert magnetic field intensity to electric signal by Hall element non-contactly with magnetic field that angle changes.Fig. 5 has illustrated the installation site planimetric map of permanent-magnet steel 12, magnetic conductor 10,11 and Hall element 16,17, from figure, can understand the situation that permanent-magnet steel 12 rotates intuitively, magnetic conductor 10,11 will be converted to magnetic field perpendicular to rotational plane to this rotary magnetic field, Hall element 16,17 will be converted to electric signal to this magnetic field intensity that induces, again by the subsequent conditioning circuit processing and amplifying.
The latter half among Fig. 6 is the graph of relation between pedal 1 rotational angle and sensor circuit signal (the being control circuit) output voltage, and the first half is the graph of relation between pedal 1 turned position and the make and break contact (being produced by the optocoupler output terminal).Can see that output voltage that pedal 1 begins to step on is about about 0.8 volt from the figure of the latter half, (rotational angle is 18 degree) output voltage was about 4.2 volts when total travel was stepped on, should be linear between rotational angle and the output voltage, error should be less than ± 2%.Can see when pedal from the figure of the first half beginning to step on and rotating 1 degree and when spending greater than 1, the output terminal impedance of optocoupler will change conducting into from open circuit that this signal will offer ECU (engine control unit) and do to judge whether accelerator pedal has action usefulness.
Fig. 7 is the block scheme of control circuit of the present utility model.Sensor 16,17 has adopted hall device, above-described induced field is converted to voltage signal by hall device, magnetic field is for elsewhere, the voltage (is 5 volts based on added operating voltage) that hall device output is 2.5 volts, the voltage that to export greater than 2.5 volts the magnetic field hall device 16,17 of positive dirction, enhancing output voltage rising along with magnetic field enters the saturation region until hall device; To export voltage less than 2.5 volts to reciprocal magnetic field hall device, along with reciprocal magnetic field increases, the output voltage of hall device drops to and enters cut-off state.The amplifying circuit that the output signal of hall device is formed via operational amplifier amplifies the back and exports ECU to by filtering circuit.Amplifying circuit can be transferred in addition and transfer full scale, and its output signal is also delivered to the level comparator circuit, and the output of comparator circuit will be controlled the conducting of optocoupler and end, and judges for ECU whether pedal moves usefulness.Processing and amplifying to electric signal makes output signal level meet the requirement of ECU to the accelerator pedal output signal level.Because ECU (engine control unit) needs input two-way analog level signal, so side circuit has two sensors and two-way voltage amplification.Concrete circuit diagram as shown in Figure 8.U1 is a four-operational amplifier among Fig. 8.U2 is a Hall element, and its output signal is delivered to discharge circuit U1B in-phase end after dividing potential drop, and U1B is the in-phase amplifier circuit, and its enlargement factor is adjusted by V R1, and (promptly adjusting full scale value) makes it to meet the requirement of Fig. 5.U1D is a follower, and its output level is through R10, VR1 to U1B end of oppisite phase, and the center tap terminal of VR2 potentiometer is transported to U1D with adjustable positive level, make U1B other put to adjust and use.The output signal of U1B exports ECU to after filtering circuit R14 and C1 filtering.The R1 role is just in case discharge circuit damages, and lower voltage signal output still can be arranged, and guarantees that ECU can continue to drive the engine tick-over.
U1C constitutes comparator circuit, and R6, R8 produce the output of fixed partial pressure value, in case pedal has action slightly, magnitude of voltage that U1B produces can drive the U1C upset, thereby drives photoelectric coupled circuit U3 action, produces switching value output signal as shown in Figure 5.
The second road amplification output circuit principle of work that ECU needs is same as described above, repeats no more.
