Vehicle independent risk avoiding system and method for operation passenger car driver under abnormal condition

Abstract

The invention belongs to the field of carrying tool application engineering, and discloses a vehicle independent risk avoiding system and method for an operation passenger car driver under the abnormal condition. By performing real-time collection data monitoring on the rotating angle of the rotating angle speed of a vehicle steering wheel, and performing calculation analysis on the collected data, whether a driver loses normal control for a car or not is judged, a signal instruction is sent out, and the car is controlled to steer and brake; meanwhile, alarm prompting is performed, and alarm information is sent to a monitoring center. After the vehicle driver is invaded by passengers and emergency diseases/damage or loses normal control over the car due to operation errors, according to the real-time traffic condition, the car is controlled to perform reasonable steering, braking and parking motions; an alarm can be given to passengers and surrounding cars; an alarm can be given to related departments through a GPS monitoring system to start an emergency plan in time, and the probability that operation cars have great accidents can be greatly lowered.

Description

technical field [0001] The invention belongs to the field of vehicle operation engineering, and in particular relates to a system and method for vehicle autonomous safety avoidance when the driver of an operating passenger vehicle is abnormal. Background technique [0002] At present, the commonly used existing technologies in the industry are as follows: in recent years, hundreds of regulations have been updated to adapt to the rapid development of the industry. Among them, the "Safety Technical Conditions for Commercial Buses" (JT / T1094-2016) clearly stipulates that the vehicles within the scope need to be equipped with intelligent systems such as automatic emergency braking system and lane keeping assist system to assist the driver to drive the vehicle safely. Assisted driving has basically reached the L1 level of unmanned driving technology, and the safety level will also be greatly upgraded. However, the driver is still the key to safe driving of the vehicle, but the dr...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the driver of an operating passenger car needs to fully control the vehicle. The automatic system required by JT / T1094 can sometimes assist the driver to complete certain driving tasks, but it cannot effectively prevent the driver from suffering sudden illness / injury, passenger When the normal control of the vehicle is lost due to malicious interference, or the operation is wrong, the vehicle is out of control and seriously threatens the safety of passengers

[0005] The difficulty of solving the above technical problems mainly lies in the fact that under the current technical conditions of vehicles and the requirements of relevant regulations and standards on the safety technology of passenger cars in operation, the driver is required to control the vehicle, and the driver suffers from sudden illness / injury, passenger harassment, How to ensure the safety of passengers when the vehicle loses the control of the driver due to an operation error
