Sõidukiandurid

Sõidukiandurid, also known as vehicle sensors, are electronic devices used in modern automobiles to monitor and measure various aspects of the vehicle's performance and environment. These sensors play a crucial role in the operation of numerous vehicle systems, including engine management, safety features, and driver assistance technologies. They collect data that is then processed by the vehicle's onboard computer, or ECU (Electronic Control Unit), to make real-time adjustments or trigger specific actions.

Common types of sõidukiandurid include the oxygen sensor (lambda sensor) which measures oxygen in the exhaust, the mass air flow sensor which determines the amount of air entering the engine, and the throttle position sensor which indicates how much the accelerator pedal is pressed. Wheel speed sensors are vital for anti-lock braking systems (ABS) and traction control, while temperature sensors monitor engine coolant and ambient air. Other important sensors include knock sensors to detect engine knocking, and various pressure sensors for oil and fuel systems.

The data gathered by these sensors enables the ECU to optimize fuel efficiency, reduce emissions, enhance engine power, and ensure the proper functioning of safety systems like airbags and stability control. Modern vehicles can contain dozens of individual sensors, each contributing to a more efficient, safer, and comfortable driving experience. Faulty sensors can lead to warning lights on the dashboard, poor performance, and increased fuel consumption, highlighting their importance in vehicle maintenance.
