A novel regenerative braking algorithm based on continuously variable transmission is proposed to make effective and maximum use of the brake energy in order to improve fuel economy. In the braking torque distribution of the novel regenerative algorithm, the regenerative torque is determined by considering the vehicle velocity, the maximal generation torque and state of the electric motor, the maximal charging power and voltage of the energy storage component. The actual driven wheels braking pressure which is reduced by the amount of the regenerative braking force is supplied from the electronic hydraulic brake system. The novel regenerative baking algorithm maximizes the actual regenerative power recuperated by the energy storage component. The simulation results show that actual regenerative power recuperation by the novel algorithm is more than the conventional one, and life-span of brake disks is also prolonged.
