Abstract
A method of coast regenerative brake cooperation control for rear wheels of an environment-friendly vehicle is provided. The method actively adjusts the generation amount of a braking force when distributing the braking force to front and rear wheels in response to reception of coast regeneration generation amount information that changes in real time.
Claims9
A method of coast regenerative brake cooperation control for rear wheels of an environment-friendly vehicle that adjusts braking forces of front wheels and rear wheels to adjust an S-braking value, which is the sum of a coast regenerative brake value and a rear-wheel regenerative brake value that are generated at the rear wheels, to be within a critical value set in advance for each deceleration section, the method comprising:
- adjusting, by a controller, the S-braking value in a first section that is a section from an initial deceleration to a first reference deceleration such that a coast regenerative brake value that has been generated is fully allowed;
- adjusting, by the controller, the S-braking value in a second section that is a section from the first reference deceleration to a second reference deceleration to decrease the coast regenerative brake value generated in the first section;
- and
- adjusting, by the controller, the S-braking value in a third section that is a section from the second reference deceleration to a third reference deceleration to maintain or decrease the coast regenerative brake value decreased in the second section.
