[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0018] This embodiment provides a method for measuring the real-time speed of a car. When the car is moving, the vehicle speed signal n from the speed sensor is collected within a period of time Δt, and the distance traveled by each pulse is Δd. The real-time vehicle speed can be measured, and the variable sampling rate algorithm is applied to make the output displayed real-time vehicle speed value fast The ground reflects the actual change of the vehicle speed, and can make the displayed data stable and reliable. It greatly reduces the visual fatigue of viewing the display while driving, and facilitates the driver to understand the speed of the vehicle.
