Regenerative Braking Cooperation Control (RBC)
The brake force application is distributed by controlling hydraulic braking and the total brake force (hydraulic + regenerative brake) output that the driver requires is generated. In the case of regenerative brake failure, the total brake force that the driver requires is supplied by the hydraulic brake system.
The AHB system is composed of the Integrated Electronic Booster (IEB).
First, the IEB generates the hydraulic pressure required for braking.
Similar to the boosting effect when the driver steps on the brake pedal in a system equipped with a vacuum booster, the hydraulic pressure stored in the cylinder is supplied to provide pressure throughout the entire brake line. Second, the IEB delivers pressure that is generated by the IEB to a caliper on each wheel. It is connected to the brake pedal to detect the brake force that is required by the driver, and to generate a brake feeling. The IEB carries out the ABS, TCS, and ESP functions as in conventional vehicles.
