Embodiment 1

[0053] A comfort-based vehicle optimization method such as figure 1 shown, including the following steps:

[0054] S1: Obtain the road surface data of the road section to be optimized and the historical vehicle data when the vehicle is driving on the road section to be optimized. The road surface data includes the road surface wavelength and road surface amplitude of the road section to be optimized, which are pre-measured by the road spectrum measurement vehicle. The value range of L is from 0.1-100m, and the value range of A is generally from 1-200mm. Historical vehicle data includes X-axis, Y-axis and Z-axis acceleration and GPS information data when driving on road sections.

[0055] S2: Extract historical vehicle data at different speeds, and obtain upper and lower limits of objective comfort at different speeds based on historical vehicle data and road surface data. Specifically, the upper and lower bounds are:

[0056] The upper limit of objective comfort is the mean...

Embodiment 2

[0088] The present invention also provides a vehicle optimization system based on comfort, including a data acquisition module, an objective comfort calculation module, a subjective comfort extraction module, an optimal speed range acquisition module, and a reminder module,

[0089] The data acquisition module is used to obtain the road surface data of the road section to be optimized and the historical vehicle data when the vehicle is running on the road section to be optimized. The historical vehicle data includes X-axis, Y-axis and Z-axis acceleration and GPS information data when driving on the road section;

[0090] The objective comfort calculation module is used to extract historical vehicle data at different speeds, and obtain upper and lower limits of objective comfort at different speeds according to historical vehicle data and road surface data;

[0091] The subjective comfort extraction module is used to obtain the historical subjective comfort data of passengers tr...

Abstract

The invention relates to a comfort-based vehicle optimization method and system. The method comprises the following steps: S1, obtaining road surface data of a to-be-optimized road section and historical vehicle data when a vehicle runs on the to-be-optimized road section; s2, extracting historical vehicle data at different speeds, and obtaining an upper limit value and a lower limit value of objective comfort at different speeds according to the historical vehicle data and the road surface data; s3, acquiring historical subjective comfort data of passengers driving the vehicle at different speeds on the to-be-optimized road section; s4, comparing the historical subjective comfort data at different speeds with the upper and lower limit values of the objective comfort, and obtaining the optimal speed range of the to-be-optimized road section; and S5, acquiring real-time speed information of a vehicle driving on the to-be-optimized road section, and reminding the vehicle speed according to the optimal speed range. Compared with the prior art, the method has the advantages of high accuracy, good optimization effect, high efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a comfort-based vehicle optimization method and system. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of national income and living standards, the number of urban motor vehicles and residents' travel volume has increased rapidly. In pursuit of higher travel quality, people are constantly improving ride comfort and timeliness. Existing data processing for evaluating ride comfort is generally done manually, that is, by collecting test riders to test ride The recorded ride experience information is manually counted and analyzed for a large amount of ride experience information to obtain the comfort level of the vehicle. [0003] However, the method of manually analyzing the comfort level is highly subjective and the data processing process is cumbersome, and the processing efficiency is not high. , payment,...
