Instead, they utilize existing wheel speed sensors from the vehicle’s anti-lock braking system (ABS) to monitor changes in tire pressure. The functionality of these sensors is grounded in relative wheel speed, which reflects tire deflation.
When a tire loses pressure, its diameter decreases, causing it to rotate faster than properly inflated tires. The indirect sensors detect these variations in rotation rates through a central control unit, interpreting the data to identify under-inflation.
Key components of indirect sensor functionality include:
- ABS Wheel Speed Sensors: They measure the speed of each wheel.
- Control Unit Assessment: The vehicle’s control system analyzes the wheel speed data.
- Alert System: If discrepancies are detected, the driver is notified through dashboard warnings.
This method, although less precise than direct sensors, provides a cost-effective solution for monitoring tire conditions effectively.
