6.7.3 System Working Principle
6.7.3.1 System Working Principle
TMPS Function Description
1. Reset
During the initial power-up or the voltage is below the reset
threshold, TPMS control unit will be in a non-operational
services status, in reset status. Once the voltage reaches
an acceptable value, TPMS control unit will be released
from the reset status, the module will enter the normal
status.
2. Initialization Mode (System Self-test)
When the ignition is turned to ON, the initialization starts.
The system will initialize I / O ports, registers, internal
variables, data storage address.
3. Start Mode
In the start mode, TPMS supports systems running:
a. Receive WE Sensors RF Data Frame
TPMS control unit continuously receives and deals with
TPMS sensors RF data frame.
b. Verify Sensor Received WE Frame Data
Upon receiving a radio frequency emitted by the WE
sensor data frame, TPMS control unit will firstly verify
the legitimacy of the message received. Sensor
information will be sent through an early warning
algorithms for processing.
c. Process Each Received Valid TPMS Sensor Message
Once a low tire pressure is detected, tire pressure
warning lamp will be lit (TREAD).
d. Continuously Monitors The K-Bus Request
TPMS control unit must be activated prior to use of the
K-bus.
e. Vehicle Moving (Wheel Speed Sensor)
Monitor whether there is a tire without speed sensor or
the spare tire is used on the vehicle.
4. Diagnostic Mode
When connecting scan tool to communicate through the K-
bus, TPMS control unit enters into the diagnostic mode.
5. Sleep Mode
When the system enters into sleep mode, it will enter a low
power consumption mode. When entering sleep mode, it
does not receive and process sensor information, or the
diagnosis command, until the ignition is detected turned on,
the system exits sleep mode.
–
Wake-up Condition
When the ignition input signal changes from the ignition
off (OFF) to ignition on (ON), the TPMS control unit exits
sleep mode.
–
Sleep Condition
When the TPMS control unit detects that the ignition
input information is off (OFF) and no pending received
RF information, TPMS control unit will enter into sleep
mode.
