Obstacle Avoidance Driving Guidance System and Guidance Method Based on Visibility

Abstract

The invention provides a visibility-based obstacle avoidance driving guidance system and a guiding method thereof. The system comprises a microwave sensor, a vehicle-mounted interior sensor, a centralprocessor, a vehicle-mounted unit, a vehicle-mounted GPS and a communication network device which are respectively mounted on a vehicle, comprises a visibility sensor and a roadside unit which are mounted on the both sides of a lane, and further comprises a signal transmitter connected to the visibility sensor; the microwave sensor, the vehicle-mounted interior sensor and a vehicle-mounted display are connected to the central processor, and the vehicle-mounted unit and the roadside unit are in communication with the communication network device. According to the visibility-based obstacle avoidance driving guidance system and the guiding method, the driver reaction time is considered in environments such as nighttime and rainy days when the visibility is low, the defect of the driver sightdistance discrimination ability is offset by means of sound, video display and the like, the driving behavior of the vehicle in a road is effectively guided, the driving behavior characteristics of the driver are met, the requirements of the vehicle for obstacle avoidance are met, and the driving safety is ensured to the maximum degree.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and more specifically, to a driving guidance system for avoiding obstacles based on visibility and a guidance method thereof. Background technique [0002] When the vehicle is driving at night, in rainy weather and other bad weather, due to the limited working distance of the vehicle headlights, the driver cannot see the road conditions ahead, and does not have enough time to react to sudden obstacles, which may easily cause traffic accidents; When an approaching vehicle turns on its high beams, the strong light will blind the driver for a short time and cause traffic accidents. With the development of intelligent vehicles, many vehicles already have obstacle detection function and anti-collision safety system, for example: 2018 Volvo XC60, 2018 Audi A4 Driver Assistance Package optional package includes preventive overall safety system, automatic high beam Lights and ...

AI Technical Summary

Problems solved by technology

The active safety and driving assistance systems of intelligent vehicles have made great progress, but there are still the following problems: First, the early warning systems of existing vehicles do not take into account the driving characteristics of the driver in the human-machine co-driving environment. Due to the influence of visibility, the early warning of the vehicle should consider giving the driver sufficient time to respond to the operation; second, the early warning system of the existing vehicle is mostly aimed at the detection of obstacles within a certain range from the vehicle, but does not pay attention to the obstacle Whether it is a static obstacle or a moving obstacle, if it is a moving obstacle, since both of them are continuously moving, the early warning of the vehicle should also be judged according to the moving trajectory of the object; the third is as a driving assistance system, in addition to driving In addition to the early warning of the police, the guidance strategy for vehicle driving should be put forward
