The SR73F large-angle obstacle avoidance 77GHz millimeter-wave radar independently developed by Nanoradar Technology adopts the advanced MIMO radar system, which can output up to 1920 obstacle information per second, with a detection distance of 0.2-40 meters, a detection angle of 112°, and ranging accuracy. ±0.1 meters. It can effectively detect moving/stationary targets, output obstacle distance, speed, angle and other information, and fully meet the needs of training and simulation tests in specific environmental areas (subject second driving test).

business challenge

As a traditional industry, motor vehicle driving training has a history of decades. In the past decade or so, the industry has adopted a training mode of hands-on teaching by coaches, which can no longer meet the needs of young students at this stage, and needs to adopt more intelligent, humanized and digital methods to solve the demands of students.

The comprehensive driving training mode equipped with ADAS (millimeter wave radar, camera, display screen) has begun to replace the traditional oral instruction mode, and the ADAS system is used to complete standardized, safe and efficient driving training without a coach in a specific environmental area (subject 2) Teaching tasks, so as to achieve the goals of reducing costs, increasing efficiency, saving energy and reducing emissions.

solution

Nanoradar provides a set of millimeter wave radar SR73F (front 1 rear 1, front 2 rear 1 or front 2 rear 2) for the coach car. SR73F is a 77GHz large-angle obstacle avoidance radar sensor specially developed by Nanoradar for the application of advanced driver assistance system (ADAS) in coach vehicles. It uses millimeter wave radar to monitor the environment in front and behind the vehicle, and detects surrounding pedestrians and obstacles in real time. Determine whether the obstacle is within the range of the driving track of the vehicle.

The timing of the braking action is determined according to the current vehicle speed, ensuring safety while reducing wrong braking actions and improving driving safety. It avoids the inconvenience for students to observe under objective and harsh weather conditions such as night, fog, and heavy rain, which may lead to the danger of collision in the blind area of ​​”vision”, and successfully guarantees the safety of students and vehicles.
