Abstract

The invention discloses a method for predicting the brake pressure of an electric vehicle, and belongs to the technical field of electric vehicles. The method comprises the steps of acquiring the brake pressure of a brake master cylinder of an experimental vehicle under various working conditions and parameters influencing the brake pressure; based on the parameters influencing the brake pressureand the brake pressure, training a nonlinear autoregressive dynamic neural network model to obtain a trained nonlinear autoregressive dynamic neural network model; and acquiring parameters influencingthe brake pressure in actual driving of the electric vehicle, and predicting the brake pressure of a brake master cylinder in the electric vehicle based on the parameters influencing the brake pressure in the actual driving and the trained nonlinear autoregressive dynamic neural network model. The technical problem that a method for predicting the brake pressure of the electric vehicle is lackedin related technologies can be effectively solved.

Description

technical field [0001] The present application belongs to the technical field of electric vehicles, and in particular relates to a method and equipment for predicting braking pressure of electric vehicles. Background technique [0002] The braking system of an electric vehicle is generally an electromechanical composite braking system, which is composed of a hydraulic braking system and a regenerative braking system. For a part of the braking force, the regenerative braking system provides another part of the braking force for the electric vehicle. The regenerative braking system provides a fixed braking force, and the braking force of the electric vehicle can be adjusted by adjusting the braking force generated by the hydraulic braking system. [0003] In the prior art, the pressure sensor on the brake master cylinder is used to collect the brake pressure of the brake master cylinder, and the brake pressure of the brake master cylinder is adjusted according to the collected...
