Problems solved by technology

From a practical point of view, the emergence of a dangerous state already means that there is a greater risk of accidents. Although this type of safety warning system can avoid some accidents, it cannot completely avoid the occurrence of dangerous driving states of commercial buses.

Abstract

The invention relates to the vehicle safety running technology and discloses a device and a method for identifying the abnormal running state of a commercial vehicle. The device comprises a single chip, a liquid crystal display screen, a data collector connected with a vehicle bus, a microwave radar used for measuring the relative distance between a vehicle and a vehicle ahead, and a visual sensor used for measuring the distance between a vehicle tire and a lane line, wherein the corresponding I / O (input / output) input end of the single chip are connected with the output ends of the microwave radar, the visual sensor and the data collector respectively; and the I / O output end of the single chip is connected with the liquid crystal display screen. According to the device, the driver operation behavior bias and the vehicle running state bias can be automatically collected, and a driver can be timely prompted when the vehicle is in the abnormal running state, so that the vehicle is prevented from entering the dangerous running state and the running safety of the vehicle is guaranteed.

Description

technical field [0001] The invention relates to vehicle safety driving technology, in particular to an identification device and an identification method for an abnormal operating state of a commercial vehicle. Background technique [0002] Many traffic accidents occur every year, resulting in casualties and a large amount of property loss, especially for long-distance commercial buses, which have long driving distances on high speeds, some reaching 1,000 kilometers or even more than 2,000 kilometers. Long-term continuous driving and fatigue driving will cause The driver's concentration state deteriorates, and the driver's ability to perceive the road traffic environment and the ability to operate the vehicle will also decline to a certain extent, so that the operating safety of commercial buses cannot be guaranteed to the greatest extent. According to the operating characteristics of commercial buses, some technicians have proposed various commercial passenger car safety mo...
