A Pothole Road Early Warning Method Based on Smartphone and Navigation Application

Abstract

The invention relates to the technical field of automobile navigation. The invention provides a bumpy pavement early warning method based on a smart phone and navigation application. The bumpy pavement early warning method can complete identification and early warning of bumpy pavements without increasing any vehicle-mounted sensors, and has the advantages of being simple and practical, being lowin cost, and being high in universality. The technical scheme of the bumpy pavement early warning method based on a smart phone and navigation application is that a map application is installed on a smart phone, and the smart phone is fixed in a vehicle at will. The bumpy pavement early warning method based on a smart phone and navigation application can perform detection with high efficiency andstability on the pavement condition by means of a social vehicle, and the coverage of detection is wide and the blind area of detection is small. The bumpy pavement early warning method based on a smart phone and navigation application does not need to install various sensors and detection devices on the vehicle, can be directly implemented by means of the smart phone, is simple and practical, isconvenient for promotion, and is low in cost. The bumpy pavement early warning method based on a smart phone and navigation application directly uses the map application on the smart phone to realizedetection and early warning of the pavements, and detection and early warning can be carried out at the same time, and the functions are diversified.

Description

technical field [0001] The invention relates to the technical field of car navigation, in particular to a pothole road early warning method based on a smart phone and a navigation application. Background technique [0002] In the daily driving process, we found that when the driver suddenly finds the potholes ahead, there are usually two situations: 1. Unable to brake at a reasonable deceleration to a safe passing speed, causing the vehicle to pass through the potholes at high speed, Damage or shorten the life of vehicle components. 2. Brake with a relatively large deceleration to a safe speed to pass. However, due to the large braking deceleration, it is very easy to cause safety accidents such as rear-end collisions. Therefore, if the pothole road ahead can be known in advance, the driver of the vehicle can safely reduce the speed and pass through it earlier, effectively avoiding damage to the vehicle and the impact on the comfort of the driver and passengers.

However, because this method requires professional modification of the vehicle, the cost is usually high. The cheap road inspection vehicle costs hundreds of thousands of vehicles, while the expensive ones reach millions.

At the same time, the use of professional inspection vehicles to detect road conditions, due to limited coverage, can easily lead to missed inspections
