14.1.1. Overview

The Tire Pressure Monitoring Controller component monitors the tire pressure and temperature signals from the tire pressure sensors. It detects low pressure, high pressure, high temperature and leakage conditions and provides warnings to the driver. The component also performs optimum pressure monitoring based on configuration parameters.

14.1.2. Functions

Title

Description

1

Tire Pressure and Temperature Monitoring

Monitors the tire pressure and temperature signals from the tire pressure sensors. Detects low pressure, high pressure, high temperature and leakage conditions based on configurable thresholds.

2

Optimum Pressure Monitoring

Monitors if the tire pressure is within an optimum range defined by configuration parameters. Provides a warning if pressure goes outside the optimum range.
