Description

Technical Field

[0001] This utility model relates to the field of circuit technology, specifically to a control circuit for active pedestrian recognition in automobiles. Background Technology

[0002] A blind spot, also known as a vehicle blind spot, refers to the area that a driver cannot directly observe from their normal driving position due to obstruction by the vehicle's body. Simply put, it's the area a driver cannot see while sitting in the driver's seat. Blind spots are typically divided into interior blind spots and exterior blind spots. Interior blind spots are sometimes caused by the vehicle's structure, and sometimes by human error. Exterior blind spots are caused by fixed or moving objects and lighting conditions; the size of these blind spots varies depending on the vehicle model.

[0003] In existing technologies, people typically adjust the side mirrors on the exterior of the car or install streaming rearview mirrors inside the vehicle to observe blind spots and improve driving safety. However, current streaming rearview mirrors are generally single-camera systems, usually installed at the rear of the car. Theoretically, the camera's field of view cannot exceed 180 degrees (due to obstruction by the vehicle body), and in practice, the maximum field of view is no more than 150 degrees. This means they cannot completely capture all the situations behind and to the sides of the car, nor can they monitor blind spots on the sides. Moreover, neither streaming rearview mirrors nor the side mirrors can actively alert users to avoid obstacles or pedestrians in blind spots, thus failing to meet user needs and providing a less than satisfactory user experience.
