Modern automobiles are equipped with various sensors integrated into the engine and other systems to monitor performance, detect issues, and enhance comfort, efficiency, and safety. These sensors can manage and assess factors such as oil pressure, temperature, pollution levels, and coolant levels, among others. Key types include LiDAR sensors, which use light detection for applications like Adaptive Cruise Control and lane variation, ultrasonic sensors that assist in safe parking by measuring distances using sound pulses, and proximity sensors, which use electromagnetic waves to warn drivers of potential collisions. These advanced sensor technologies enable precise monitoring and response to internal and external conditions, improving the overall driving experience and vehicle functionality.
