Abstract

The invention discloses an electric braking effect evaluation method and device, and belongs to the technical field of automobile electronic products. The method includes the steps of obtaining braking data; grouping the obtained braking data according to the braking processes, wherein each group of braking data include the braking data belonging to the same braking process; calculating the change rate of the braking data in each group; obtaining the time when the change rate of the braking data in each group arrives at the preset section and the time duration when the change rate is located in the preset section according to the change rate of the braking data in each group. The scheme is used for effectively evaluating parameters of an electric braking controller.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method and device for evaluating electric braking effects. Background technique [0002] With the rise of oil prices and the general trend of national energy conservation and emission reduction, the fuel consumption of automobiles has gradually become an issue that everyone pays more and more attention to. How to reduce fuel consumption and improve the power and economy of the vehicle is a major topic of practical significance for vehicle manufacturers and users. [0003] Electric braking (also known as: regenerative braking) can convert the kinetic energy of the vehicle into electrical energy and store it when braking. The use of electric braking can greatly improve the fuel efficiency of the vehicle, especially in urban working conditions where frequent braking is required, and the fuel efficiency has been greatly improved. In the process of product design, t...
