Are mutinous resistors and Hall's accelerator pedal common?

Not the same, not universal. The electric car sends a signal to the controller by the Hall sensor, and the motorcycle is a carburetor operated by the throttle line. You can ask me any other questions.

Extended data:

The permanent magnet is linked with the accelerator pedal. When the accelerator pedal is depressed, the accelerator shaft drives the permanent magnet to rotate together, which changes the relative position between the magnet and the Hall element, thus changing the angle of magnetic field lines entering the Hall element and the voltage value output by the Hall element. There is a linear relationship between the output voltage of the Hall element and the position of the accelerator magnet, and the angular displacement of the accelerator pedal can be measured by measuring this Hall voltage. As can also be seen from Figure A, the sensor * * * has four pins, one of which is a male * * iron tapped pin and the other is a 5V male * * power supply. The other two pins are respectively connected with the electronic control unit to send their respective Hall signals to the electronic control unit, and the electronic control unit judges the throttle opening according to the two input signals of the Hall sensor. If ECU judges that there is something wrong with a Hall sensor, it will remember the fault code, but the fault light will not light up. If both Hall sensors have problems, the ECU will not only remember the fault code and make the fault light flash, but also start the protection function to make the engine only idle, that is, start the home function.

Figure b shows the magnetic ring Hall effect throttle position sensor.

As can be seen from Figure B, the magnetic ring Hall effect throttle position sensor is composed of a rotatable magnetic ring rotor composed of a permanent magnet, and several fixed magnets and Hall blocks. As can be seen from the figure, the Huole block is sandwiched between two semi-circular magnets, and the periphery of the two semi-circular magnets is a rotor magnetic ring composed of permanent magnets. The magnetic lines of the magnetic field generated by the magnetic ring can pass through the Hall block through two semicircular magnetizers, so that the Hall block generates voltage. If the magnetic ring rotates with the throttle opening, the angle of the magnetic field generated by the magnetic ring passing through the Hall block will change. Therefore, the output voltage of the Hall element will change accordingly. Through reasonable structural design, the Hall voltage can change linearly with the rotation of the magnetic ring.

Hall throttle position sensor should be provided with stable power by electronic control unit, and its voltage value is generally 5V or 8V. The output voltage signal is very weak and needs to be amplified by an amplifier circuit. If this analog signal needs to be converted into digital signal, an A/D conversion circuit is often needed in the integrated circuit.

Generally, a sensor has three pins, namely, a power input pin, a signal output pin and a male ground pin. This kind of sensor is non-contact, so it has no wear, high precision and long service life, and is widely used in diesel engines.

Crankshaft position sensor and camshaft position sensor

The crankshaft position sensor and camshaft position sensor only provide crankshaft speed signal, crankshaft position signal and cylinder judgment signal to the electronic control unit, so that the power control unit can determine the fuel injection quantity and fuel injection timing. Some diesel engines do not need cylinder judgment signals, and the accurate distribution of high-pressure fuel to each cylinder depends on the correct installation of the engine and fuel pump. As long as it is installed according to the installation mark, the fuel injection will not be disordered. However, most electronically controlled diesel engines need camshaft to provide cylinder judgment signal.
