Vehicle inside passenger dangerous state alarming device and alarming method

Abstract

The invention discloses a vehicle inside passenger dangerous state alarming device and alarming method. The device comprises a microprocessor, a plurality of left side infrared sensors, a plurality of right side infrared sensors, a left camera, a right camera and signal lamps, wherein the left side infrared sensors and the right side infrared sensors are used for obtaining whether a limb of a passenger stretches out of a corresponding vehicle window or not, the left camera and the right camera are used for collecting images of the limb of the passenger and images of an obstacle, and the signal lamps are used for conducting alarming according to alarming signals given out by the microprocessor. The infrared sensors installed on the upper edges of outer portions of vehicle windows and used for obtaining whether the situation that the limb of the passenger stretches out of the corresponding vehicle window exists or not, in the situation that the limb of the passenger stretches out of the corresponding vehicle window, the cameras installed on vehicle rearview mirrors obtain images of the rear portion of the vehicle, the microprocessor processes the images through the image processing technology, the gap between the part, stretching out of the vehicle window, of the limb of the passenger and the obstacle is identified, the state safety of the passenger is evaluated, evaluation results are divided into a dangerous type, a slight dangerous type and a safety type, and a driver is prompted with the evaluation results through the signal lamps with different colors.

Description

technical field [0001] The invention relates to the field of occupant protection in a vehicle, in particular to an alarm device and an alarm method for the dangerous state of an occupant in a vehicle. Background technique [0002] At present, the number of motor vehicles is increasing rapidly, and in the case of limited road resources, congestion is becoming more and more common. In order to alleviate congestion and achieve the purpose of fast passage, vehicles often have congestion or multiple vehicles in a lane; however, the safety awareness of the occupants is not high, and there are often dangerous behaviors where the occupants' heads or limbs stick out of the window ; In cities, especially in areas with city gates, bridge piers and three-dimensional traffic, if the above-mentioned vehicles are blocked or there are multiple vehicles in parallel in the same lane, the distance between vehicles, city gates, bridge piers and other vehicles and other obstacles If the occupan...

Problems solved by technology

During driving, the rearview mirror is used to obtain information such as whether the occupant is sticking out the window, but the field of view of the rearview mirror is limited, and the driver's gaze point is only one at a time, and too much observation of the rearview mirror will cause the driver to be confused. The reduction in the acquisition of traffic information ahead is not conducive to driving safety. Under such circumstances, the development of a system that automatically recognizes whether the occupant's limbs are sticking out of the window and prompts the driver has practical application value
