Structure and features
|
• |
Wheel angular velocity of wheels are different from each other in the
following cases:
|
1) |
Slip for each axis occurs differently.
|
2) |
Rotation radius (the radius of curve) for each wheel is different.
|
3) |
Tire wear, internal pressure, tire specifications, etc. for each 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 on receiving
RF signals from the sensor.
|
• |
Every time RF signals from sensor IDs 1, 2, 3, and 4 are received, the
ID with the highest correlation among the phase of each collected wheel
is transmitted. (In other words, each time RF signal is received, the
phase of the tire is transmitted to the most constant wheel.)
|
• |
TPMS sensor transmits the RF signal at intervals of 16 seconds in the
learning mode.
|
• |
After stopping or parking for more than 19 minutes, automatic learning
function in every driving position is performed.
|
• |
The sensor is converted to Parking Mode when stopped or parked for more
than 15 minutes. When acceleration of over 4g (15-20km/h) is detected
in Parking Mode, it is converted to First Block Mode.
