Abstract

The present application discloses a speed prediction method, device and electronic device, and relates to the field of intelligent transportation. The specific implementation scheme is: obtaining data through the IMU; obtaining a prediction result based on the data, wherein the prediction result includes at least one of predicted acceleration and predicted state information, and the predicted state information is used to indicate whether the vehicle is zero speed state; according to the prediction result, determine the target predicted speed. In this way, the vehicle-mounted terminal can use the IMU to predict the speed of the vehicle in a scenario where the satellite signal cannot be obtained, thereby improving the accuracy of the vehicle speed prediction.

Description

technical field [0001] The present application relates to intelligent transportation technology in the field of computer technology, and in particular to a speed prediction method, device and electronic equipment. Background technique [0002] During the driving process of the vehicle, the vehicle speed is an important data that the vehicle terminal needs to obtain. For example, the vehicle terminal can remind the driver of speeding according to the vehicle speed, and calculate the pose of the vehicle according to the vehicle speed. [0003] At present, the vehicle speed obtained in some scenarios is not accurate. For example, in the rear-mounted scenarios such as car boxes or rearview mirrors, it is often impossible to obtain accurate real-time vehicle speed. In this case, satellite signals can be used. For example, Global Positioning System (GPS for short) signal to obtain the speed of the vehicle. However, in tunnels, underground passages and other underground sections, ...
