Embodiment Construction
[0038] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.
[0039] Such as figure 1 , Table 2 and figure 2 As shown, a smart phone-based road driving quality detection method includes the following steps:
[0040] 1. Install the driving vibration data collection application on the smartphone Huawei P10, and fix the smartphone on the front windshield of the Honda CRV vehicle in a bracket state;
[0041] 2. The smart phone collects road driving data at a frequency of 10Hz through the built-in acceleration sensor and GPS, mainly including driving time time; driving speed v′; driving three-axis vibration acceleration a′ x , a' y , a' z ;Real-time driving position information latitude, longitude;
[0042] 3. The mobile phone system filters the original data, rejects the collected data with a driving speed of less than 20km / h and greater than 85km / h, and uses 100 meters as the basic unit to calculate th...

The invention provides a method for detecting road driving quality based on a smart phone, and belongs to the field of transportation engineering. A road driving quality evaluation result based on smart phone vibration data is obtained through the triaxial vibration acceleration, time, speed, position and other information generated in the road driving and collected by a built-in sensor of the smart phone and the processing and analysis of data according to the road driving quality evaluation method of China. The method realizes the intelligent detection and evaluation of road driving qualityby utilizing the vibration detection auxiliary function of the smart phone, and improves the level of intelligent detection of road driving quality. The method for detecting and evaluating the road driving quality has high intelligence and low detection cost and is convenient to use. The evaluation result can be used for the real-time monitoring of road driving quality, and the aid decision makingfor road maintenance and management.
Description
technical field [0001] The invention relates to the field of traffic and transportation engineering, in particular to a method for detecting road surface running quality based on smart phones collecting driving vibration. Background technique [0002] With the development of my country's highway traffic and the improvement of people-oriented concepts, road users are paying more and more attention to road service quality. Driving comfort is the most direct reflection of road service level. It is mainly affected by the smoothness of the road surface. On the one hand, the speed affects the comfort of driving, and on the other hand, it also directly affects the safety of driving and the fuel consumption, mechanical wear, exhaust emission, and driving speed of the car. [0003] The road quality index RQI (Riding Quality Index) in the current "Highway Technical Condition Evaluation Standard" (JTG 5210-2018) is a technical index that characterizes the road surface driving quality an...
