An intelligent identification and warning system and method for safe driving of motor vehicles

Abstract

The invention discloses an intelligent identification and warning system and method for safe driving of a motor vehicle. The system includes a video image acquisition and processing unit, a main control unit, a gear handle pressure sensor unit and a voice or sound and light reminder and warning unit; the video image acquisition and processing unit The unit is used for live video image acquisition, image processing and driving feature information extraction during the driver's driving process; the gear handle pressure sensor unit is used to obtain real-time perception and confirmation of the driver's actions of pushing, pulling and holding the gear handle; the main control unit, It is used to judge whether the driver is in an unsafe driving state based on the extracted information of the video image acquisition and processing unit and the sensing information provided by the gear pressure sensor unit; the voice or sound and light reminding and warning unit is used for the driver to be in an unsafe driving state. Status alerts. The present invention comprehensively utilizes various sensing / perception units to perform information fusion to determine whether the driver is in an unsafe driving state, and if so, a warning reminder is given, which can monitor the driving state of the motor vehicle in real time and improve driving safety.

Description

technical field [0001] The invention belongs to the technical field of safe driving of motor vehicles, and in particular relates to an intelligent identification and warning system and method for safe driving of motor vehicles. Background technique [0002] The safe way of driving a motor vehicle has been learned during driver training. Safe driving requirements: The driver holds his hands at the 9 o'clock and 3 o'clock (3-9 o'clock) directions of the steering wheel, looks ahead, and properly observes the left and right rearview mirrors; when starting, parking and shifting gears, the driver's right hand You need to leave the steering wheel, operate the gear lever and cooperate with the pedals to complete the relevant operations. [0003] In real life, some drivers cannot drive safely in strict accordance with the above requirements, for example: one hand off the steering wheel without doing any driving-related operations; instead of looking directly at the road ahead, looki...
