Both technician A and technician B.<\/p>\n\n\n\n<p>Both technicians provide accurate information regarding the use of ultrasonic sensors in vehicles, particularly in the context of autonomous and driver-assist systems.<\/p>\n\n\n\n<p>Technician A is correct in stating that ultrasonic sensors are typically used in park assist applications. These sensors are a foundational technology for parking sensor systems. They are usually mounted on the front and rear bumpers of a vehicle. The system works by emitting high frequency sound waves, which are beyond the range of human hearing. When these waves encounter an obstacle, such as another car, a curb, or a wall, they bounce back to the sensor. The vehicle&#8217;s computer calculates the distance to the obstacle based on the time it takes for this echo to return. The driver is then alerted to the proximity of the object through a series of audible beeps that increase in frequency as the vehicle gets closer, or through a visual display on the infotainment screen. This application is crucial for low speed maneuvering and preventing minor collisions during parking.<\/p>\n\n\n\n<p>Technician B is also correct by describing the effective operating range as approximately two to four yards. This range, which is about 1.8 to 3.7 meters, accurately reflects the typical performance of these sensors in automotive applications. While some sensors may detect objects slightly farther away, their primary effective and reliable range for parking assistance is short. This limited range is actually advantageous for parking, as it allows the system to focus on the immediate surroundings without being triggered by distant, irrelevant objects. Compared to other sensor types like radar or LiDAR, which have much longer ranges and are used for functions like adaptive cruise control, the short range of ultrasound is what makes it perfectly suited for close quarters detection. Therefore, both statements are correct descriptions of the technology.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/08\/learnexams-banner5-88.jpeg\" alt=\"\" class=\"wp-image-278864\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The Correct Answer and Explanation is: The correct answer is A.
