The two sets of source data of elevation and latitude and longitude used in this method are not affected by the acceleration and deceleration of the vehicle, and are not affected by whether the sensor is installed horizontally. The elevation derived slope calculated by the two does not have the problem of calibrating the initial installation angle. There is no need to calibrate the initial installation angle of the sensor; however, due to the slow update frequency of the elevation and latitude and longitude, the elevation-derived slope is only the average slope between two GPS points, and the numerical accuracy is low. It is impossible to obtain the subtle road gradient in time during the fast driving of the vehicle. Change, that is, the update frequency is slow and the data accuracy is insufficient

Description
technical field [0001] The invention relates to the technical field of slope measurement, in particular to a road slope measurement method and a computer-readable storage medium. Background technique [0002] With the rapid development of cities and the increasing number of cars, energy saving and emission reduction has become the theme of transportation development. As a common road form, ramps are scattered in the traffic network, which has a great impact on the fuel consumption of vehicles during driving. The demand for establishing a real-time monitoring road slope model is becoming more and more urgent. [0003] In the actual project application scenario, it is required to install a set of integrated navigation sensors on the vehicle to measure the road slope in real time. The output of the sensor contains information such as attitude angle, latitude and longitude, and elevation. There are currently two ways to obtain the road slope from it: [0004] Mode 1, directly ...
