Electric Vehicle Regenerative Braking Control Strategy Based on Braking Time Identification
Abstract: The angular velocity
and displacement variation of the brake pedal with time during braking is studied.
Using brake angular velocity as the judgment basis of the moving window
algorithm, established the function model between the brake pedal angular
velocity and displacement. Regenerative braking time was identified accurately,
using brake angular velocity integral quantity. On this basis, analyzed the
battery can accept the maximum charge current, with feedback cur-rent as the
control object, considering the reasonable distribution of regenerative braking
and hydraulic braking force, the regenerative braking control strategy based on
braking time was proposed. The tests verify the feasibility and effective-ness
of the braking time identification algorithms and the strategy for braking
force distribution.
