Embodiment Construction
[0136] The present invention will be further described below in conjunction with accompanying drawing.
[0137] Such as figure 1 The sensor module of the automatic driving system shown includes a front camera 10 , a rear camera 16 , a millimeter wave radar set 30 and an ultrasonic radar set 31 . The front camera 10 is used to recognize lane lines, traffic markings, traffic signs and obstacles in front of the vehicle. The rear camera 16 is used to identify lane lines and obstacles behind the vehicle. The millimeter-wave radar group 30 includes a plurality of short-range millimeter-wave radars and one or more medium-range millimeter-wave radars, and each short-range millimeter-wave radar can cover all areas of 360° around the vehicle for detecting obstacles, and judge the position and speed of the obstacles. The medium-range millimeter-wave radar is used to detect obstacles in front of the vehicle and determine the position and speed of the obstacles. The ultrasonic radar gr...

Abstract
The invention discloses a sensor module of an automatic driving system, an automatic driving system and an automatic driving method. The sensor module comprises a front camera, a rear camera, a millimeter-wave radar group and an ultrasonic-wave radar group, and is characterized in that the front camera is used for recognizing lane lines, traffic marking lines, traffic signs and obstacles in front of a vehicle; the rear camera is used for recognizing lane lines and obstacles in rear of the vehicle; the millimeter-wave radar group comprises a plurality of short-range millimeter-wave radars and one or more middle-range millimeter-wave radars, the short-range millimeter-wave radars can cover all areas around the vehicle within 360 degrees and are used for detecting obstacles within the coverage scope and judging the position and the speed of the obstacles, and the middle-range millimeter-wave radars are used for detecting obstacles in front of the vehicle and judging the position and the speed of the obstacles; and the ultrasonic-wave radar group comprises a plurality of ultrasonic-wave radars, can cover all areas around the vehicle within 360 degrees and are used for detecting obstacles. The sensor module disclosed by the invention improves the reliability of the automatic driving system and reduces the security risk.
Description
technical field [0001] The invention belongs to automatic driving technology, and in particular relates to a sensor module of an automatic driving system, an automatic driving system and a method. Background technique [0002] The automatic driving system is an active safety system that can automatically control the operation of the vehicle, including driving, changing lanes, parking, etc., which improves the driving experience and comfort while ensuring driving safety. At present, the automatic driving system mainly uses sensors installed in the vehicle, such as: millimeter-wave radar, lidar, camera and ultrasonic radar, etc., to detect and recognize the driving environment, including lane lines, surrounding vehicles, pedestrians, obstacles, traffic lights, traffic signs, etc. , Safely and efficiently automatically control vehicle driving while obeying traffic rules. [0003] Specifically, when driving, use the front camera of the vehicle to identify the lane line and cont...
