Regenerative Braking Cooperation Control (RBC)
The brake force apportion 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 following are the details of regenerative braking cooperative control.
- The red wire in the diagram indicates hydraulic pressure change.
- "I": Braking is conducted by the regenerative braking (Initial stage of braking).
- "II": Braking is conducted by the hydraulic brake.
- "III": Regenerative braking range extends as hydraulic brake decreases.
- "IV": Rapidly increasing of hydraulic pressure to meet the required brake amount because the regenerative braking is dropping due to very low kinetic energy when the vehicle almost comes to a stop.
