Slope recognition method, device, equipment, readable storage medium and program product

Abstract

The application discloses a slope recognition method, device, equipment, readable storage medium and program product, and relates to the technical field of communication. The method includes: acquiring ephemeris data and terminal sensing data within a target time period, wherein the terminal sensing data includes acceleration data of the terminal within the target time period; determining the cumulative distance increment of the satellite based on the ephemeris data; Incremental and terminal sensing data are estimated to obtain the motion acceleration of the terminal within the target time period; the acceleration data in the terminal sensing data is adjusted with the motion acceleration to obtain the slope angle; based on the slope angle, the terminal is determined to be within the target time period Inside the ramp road segment. Through the above method, the acceleration data is adjusted with the motion acceleration to obtain a terminal acceleration with higher accuracy, so as to more accurately identify that the terminal is located on a slope road section. This application can be applied to various scenarios such as cloud technology, artificial intelligence, intelligent transportation, maps, travel navigation, and automatic driving.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular to a slope identification method, device, equipment, readable storage medium, and program product. Background technique [0002] Road slope is an important parameter that affects the safe driving and stable handling of vehicles. Correct slope recognition can effectively judge whether the current vehicle is in the state of going uphill or downhill or going up and down the viaduct, so as to assist driving safety. [0003] In related technologies, the sensors mounted on the vehicle are usually used to obtain data information such as wheel speed, brake master cylinder pressure, and engine torque change rate when the vehicle is in motion, and determine the acceleration of the vehicle during motion, thereby identifying the location of the vehicle. The slope of the road. [0004] However, in the above method, the data information acquired by the sens...

Problems solved by technology

[0004] However, in the above method, the data information obtained by the sensors mounted on the vehicle itself cannot adapt to environmental changes in real time, for example: in rainy weather, slippery roads will reduce the friction between the tires and the ground

Correspondingly, the misjudgment rate of the data information obtained by the vehicle sensor is high, and it is impossible to accurately identify the slope.
