Is ABS Tire Pressure Monitoring Safe?
2 Answers
ABS tire pressure monitoring is referred to as a passive tire pressure monitoring system, which provides significant assistance to driving safety. The understanding of the ABS system can be summarized in the following two aspects: 1. How ABS tire pressure monitoring works: ABS tire pressure monitoring compares the rotational speed differences between tires using the wheel speed sensors of the car's ABS system to achieve the purpose of monitoring tire pressure. ABS uses wheel speed sensors to determine whether a wheel is locked, thereby deciding whether to activate the anti-lock braking system. When tire pressure decreases, the vehicle's weight causes the tire diameter to shrink, leading to changes in vehicle speed. These changes can be used to trigger an alarm system to warn the driver. 2. Classification of tire pressure monitoring: Tire pressure monitoring systems can be divided into two types: one is an indirect tire pressure monitoring system, which determines whether a tire is abnormal by the difference in rotational speed between tires; the other is a direct tire pressure monitoring system, which involves installing four tire pressure monitoring sensors inside the tires to automatically and real-time monitor tire pressure and temperature while the car is stationary or in motion. It also provides timely alerts for high pressure, low pressure, and high temperature in tires to avoid traffic accidents caused by tire failures, ensuring driving safety.
As an average driver with nearly a decade of experience, the ABS-based tire pressure monitoring system in my car has genuinely helped me avoid many troubles. This system detects tire pressure issues by analyzing speed differences via brake sensors, triggering a warning light when pressure drops so I can promptly get it checked. Once on the highway, its alert led me to refill air at a service station, preventing a potential blowout. Though it doesn’t directly measure pressure and may respond slower in scenarios like crawling traffic or sharp turns, overall it’s reliable—preventing loss of control or blowouts due to leaks. For safety, I consider it indispensable. While less precise than advanced systems, paired with my pre-drive visual checks, it significantly boosts safety. I’ve noticed occasional false alarms on extreme surfaces like muddy roads, but this doesn’t undermine its daily protective value. Regular maintenance plus this system makes driving far more reassuring.
