TPMS Automatic location Learning
• |
Wheel angular velocity of each wheel is different when the two
following reasons:
|
1. |
Slip per each axis will occurs different.
|
2. |
Rotation radius(the radius of curve) per each wheel is different.
|
3. |
Tire wear, internal pressure, tire specifications, etc per tire
are different.
|
• |
TPMS sensor is transmitred 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(15~20km/h).
