Description

technical field [0001] The invention relates to the field of vehicle-mounted radar systems for smart cars, in particular to a miniature photoelectric integrated radar sensor for smart cars. Background technique [0002] With the ever-changing development of the smart car electronics industry, advanced smart driving assistance systems have become an essential configuration to bring people a more comfortable, convenient and safe driving experience. Advanced driving assistance system refers to the use of sensing, communication, decision-making and execution devices installed on the vehicle to monitor the driver, the vehicle and its driving environment and assist the driver through images, lights, sounds, tactile prompts / warnings or controls. The general term for various systems used by the driver to perform driving tasks or actively avoid / mitigate collision hazards. For the driving environment of smart cars, there are currently many monitoring and alarm methods, such as microw...

AI Technical Summary

Problems solved by technology

For the driving environment of smart cars, there are currently many monitoring and alarm methods, such as microwave radar, video monitoring, ultrasonic monitoring, etc., and the single monitoring method has certain defects, so the information obtained is not comprehensive and cannot realize intelligent monitoring. At the same time, the use of multiple detection and alarm methods will inevitably introduce multiple detection sensors, which put forward higher requirements for the low cost and installation complexity of the smart car monitoring system.
