TPMS Automatic location Learning
- Wheel angular velocity of each wheel is different when the two following reasons:
- Slip per each axis will occurs different.
- Rotation radius (the radius of curve) per each wheel is different.
- Tire wear, internal pressure, tire specifications, etc per tire are different.
- TPMS sensor is transmitted to RF signal at only specific phase (the angle of the tire) in the learning mode.
- TPMS receiver checks each tire phase (tire angle) information from when receiving RF signals from the sensor.
- RF signal of sensor ID 1, 2.3, 4 is received every time, transmit to ID of the most highly correlation among the phase of each collected wheel. (RF signal reception every time, the phase of the tire is transmitted to the constant wheel.)
- TPMS sensor transmits the RF signal at intervals 16 seconds in the learning mode.
- After stop or parking more than 19 minutes, automatic learning for every driving position is performed function.
- The sensor is converted into Mode Parking when stopping or parking more than 15 minutes, and Mode Parking is converted into Mode First Block when detecting acceleration over 4g (15-20 km/h).
