The invention discloses an intersection emergency braking system. Three sensing assemblies for sensing front obstacle information are installed on an automobile, each sensing assembly comprises a radar and a camera, the sensing assemblies output sensing signals to a domain controller, the domain controller outputs a control signal to an executing mechanism, one sensing assembly is fixed at the middle position in front of the automobile, the collecting direction is towards the front of the automobile to obtain the front obstacle information of the automobile, one sensing assembly is fixed at the left front position of the automobile, the collecting direction is towards the left front of the automobile to obtain the left front obstacle information of the automobile, the last sensing assemblyis fixed at the right front position of the automobile, and the collecting direction is towards the right front of the automobile to obtain the right front obstacle information of the automobile. Thesystem has the advantages that the cameras and the microwave radars can be used for large-range and long-distance detection, so that the safety of automobiles passing through an intersection is ensured, and accidents caused by human negligence and blind areas of visual fields are avoided.
Description
technical field [0001] The invention relates to the field of automobile electronic control, in particular to an intersection emergency braking system based on microwave radar and camera fusion. Background technique [0002] With the continuous development of automotive electronics technology, cars have gradually become the main means of transportation for people to travel, and there are higher standards for driving safety and comfort, so that intelligent driving of vehicles has received more and more attention. The microwave radar has a long detection distance and high precision, and can identify the relative position of objects, which can meet the requirements of the vehicle's all-weather adaptability; the camera has a long detection distance, and can perform object recognition, and the recognition rate of the target is high and accurate; the two The fusion of various sensor types can well judge the current road position of the vehicle and the real-time environment around t...
