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

Abstract

The invention discloses a ramp identification method and device, equipment, a readable storage medium and a program product, and relates to the technical field of communication. The method comprises the following steps: acquiring ephemeris data and terminal sensing data in a target time period, wherein the terminal sensing data comprises acceleration data of a terminal in the target time period; determining a cumulative distance increment of the satellite based on the ephemeris data; estimating the motion acceleration of the terminal in the target time period through the accumulated distance increment and the terminal sensing data; acceleration data in the terminal sensing data are adjusted according to the motion acceleration, and a ramp inclination angle is obtained; and determining that the terminal is located on the ramp section in the target time period based on the ramp dip angle. Through the above mode, the acceleration data is adjusted according to the motion acceleration, the terminal acceleration with higher precision is obtained, and the condition that the terminal is located on the ramp road section is identified more accurately. The method and the device can be applied to various scenes such as cloud technology, artificial intelligence, intelligent traffic, 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.
