The AUTOOL X91 TPMS is a Tire Pressure Monitoring System that combines TPMS, GPS Head Up Display, and Vehicle Slope Meter functionalities into a single device. It is designed to enhance driving safety and provide comprehensive vehicle information to the driver.
Function Description
The X91 TPMS integrates several key features:
- TPMS (Tire Pressure Monitoring System): Monitors tire pressure and temperature in real-time, providing alerts for low pressure, high pressure, and high temperature. It supports up to four tires and displays individual tire data.
- GPS Head Up Display (HUD): Displays essential driving information such as speed, altitude, longitude, latitude, and compass direction directly in the driver's line of sight, reducing the need to look down at the dashboard.
- Vehicle Slope Meter: Measures the vehicle's roll and pitch angles, providing real-time data on the vehicle's inclination. This is particularly useful for off-road driving or navigating uneven terrain.
- Automatic Monitoring of Vehicle Driving Conditions: The device automatically monitors various driving parameters and provides alerts for potential issues.
- Adjustable Screen Brightness: The display brightness automatically adjusts based on ambient light intensity, ensuring optimal visibility day and night.
- Free-Wheel Rotation Feature: The device features a free-wheel rotation design, allowing for flexible positioning and viewing angles.
- High-Definition Display: Equipped with a high-resolution colored screen for clear and crisp data presentation.
- Carbon Fiber Exterior: The device boasts a carbon fiber exterior body design, offering durability and a sleek aesthetic.
- Auto On/Off (Sleep Mode): The device automatically turns on when the engine starts and enters sleep mode when the engine is off, conserving power.
The display interface includes several key indicators:
- Roll Angle Display (A): Indicates the real-time reading of the vehicle's roll angle, with a range of -40° to +40°.
- Pitch Angle Display (B): Shows the real-time reading of the vehicle's pitch angle, with a range of -40° to +40°.
- Digital Pitch Angle Display Area (C): Displays the numerical value of the pitch angle.
- Digital Roll Angle Display Area (D): Displays the numerical value of the roll angle.
- Ound Indication Icon (E): An instrument status icon that illuminates and stays on when a normal sound level is detected, and flashes when a hidden sound is detected.
- TPMS Tire Pressure Monitoring Area (F): Displays real-time tire pressure and temperature, with an alarm function for 4 tires.
- One-Speed Alarm Indication Icon (G): Flashes and emits an audible sound when the vehicle speed exceeds the preset speed limit (default is 120KM/H).
- GPS Satellite Speed Display Area (H): Shows the live vehicle speed.
- Latitude and Longitude Display Area (I): Displays real-time updates of vehicle coordinates.
- Fatigue Driving Alarm Indication Icon (J): Illuminates when the instrument keeps on working for over 4 hours.
- Compass Display Area (K): Provides real-time updates of directional position.
- Satellite Signal Indication Icon (L): Flashes continuously when there is no satellite signal or searching for pending signals, and stays on after receiving the signal.
- Altitude Display Area (M): Displays real-time updates of vehicle altitude.
- GPS Satellite Time Display Area (N): Shows real-time updates of clock information.
- Battery Voltage Display Area (O): Displays the current battery voltage value.
