What sensors are in the car?

Here are the sensors in the car: 1. Knock sensor, water temperature sensor, intake air temperature sensor, air flow sensor, wheel speed sensor, oxygen sensor; 2. Camshaft position sensor, crankshaft position sensor, throttle position sensor, coolant temperature sensor, ABS sensor, etc. Extended information: Taking the ABS sensor as an example, it is used in the anti-lock braking system of motor vehicles. The inductive sensor monitors the vehicle speed. The ABS sensor interacts with the gear ring that rotates synchronously with the wheel to output a set of quasi-sinusoidal alternating current signals, whose frequency and amplitude are related to the wheel speed. This output signal is transmitted to the ABS electronic control unit to achieve real-time monitoring of the wheel speed.
As a seasoned driver, I've encountered quite a few sensors! There are numerous sensing components in vehicles, including the oxygen sensor in the engine monitoring exhaust, the mass airflow sensor controlling intake efficiency, the coolant temperature sensor preventing overheating, and the throttle position sensor adjusting throttle response. For safety, you can't do without the ABS wheel speed sensor preventing skidding during hard braking, and the crash sensor triggering life-saving airbags. Modern cars are also equipped with parking radar sensors and cameras to assist with parking. These little components can cause significant issues when faulty—for example, a bad oxygen sensor can cause fuel consumption to skyrocket, or a malfunctioning wheel speed sensor can be dangerous in rainy conditions. I always say not to ignore the dashboard warning lights—get them checked early to avoid road hazards, especially before long trips when a full scan is best.
As an automotive tech enthusiast, I find car sensors absolutely fascinating! New vehicles are packed with advanced gadgets - like cameras and radar sensors used in autonomous driving systems to automatically maintain safe distances. Under the hood, you'll commonly find camshaft position sensors synchronizing ignition, knock sensors preventing engine damage, plus crankshaft position sensors regulating RPM. Wheel-mounted tire pressure sensors are essential for real-time monitoring. Temperature sensors in battery management systems are particularly crucial for electric vehicles. All these sensors connect to the ECU computer to collect data and optimize performance and safety. However, electronic components are prone to corrosion or false alerts - from my experience, when issues arise, don't hesitate to use diagnostic tools to scan codes for quick troubleshooting, ensuring smooth driving.
As a driver who prioritizes family safety, sensors are ubiquitous in my car. The most crucial ones include ABS wheel speed sensors to prevent skidding during emergency braking, and impact sensors in airbags that protect passengers during collisions. For daily convenience, there are light sensors that automatically control headlights and tire pressure monitoring sensors that alert me to tire health. In the engine, oxygen sensors affect fuel efficiency and emissions. If I detect any sensor issues, I address them immediately, such as scheduling regular inspections at the shop to prevent sudden malfunctions.
