Tire pressure monitoring
System description
■ It’s an auxiliary system installed on the vehicle to real-time monitor the parameters
such as tire pressure and display and alarm by visual and acoustic signals, in order to
improve the driving safety and comfort of vehicle and reduce the accelerated wear of
tires and power consumption of vehicle due to insufficient air pressure.
■
The tire pressure monitoring system is composed of tire pressure monitoring module,
tire pressure monitoring control module, and display part. The tire pressure monitoring
module is installed at the air valves of radial tires (Vacuum tires). The tire pressure
monitoring control module is installed within the vehicle and the display part is realized
by the instruments.
■
The instrument information is divided into driving information and prompt information.
If there is no prompt information, the driving information is constantly displayed. The
user can use the button on the steering wheel to enter the menu, switch over
to driving information interface by buttons and , and select the tire pressure
display by buttons , and .
■
Refer to 8-1 Vehicle Specification for the standard pressure of this vehicle.
■
The pressure value is displayed in different units and three units are provided at your
choice, namely kPa~psi~bar. The display accuracy is 1 for values in unit of kPa or psi
and is 0.1 for values in unit of bar. Among these units, 1(psi)=6.895(kPa) and
1(bar)=100(kPa). The pressure unit is switched over simultaneously for four tires.
■
The temperature value is displayed in different units and two units are provided at your
choice, namely °C ~ °F, with the display accuracy at 1. The conversion relationship
between Centigrade and Fahrenheit degrees is n°C =(9/5•n+32) °F. The temperature
unit is switched over simultaneously for four tires.
The features of this system are as below:
■
Humanized design and human-machine interface. The information is displayed by
instrument LCD screen, featuring high reliability, beauty, practicability, and
simpleness.
■
Alarm in event of under-low tire pressure and quick leakage.
■
Simultaneous display of air pressure for 4 tires.
■
Real-time monitoring on variation of tire pressure.
