Abstract

A system used in conjunction with a hybrid flywheel drive. The hydraulic service brake system is conventional. The continuously variable transmission, flywheel, and control system for hybrid operation is super-imposed on the hydraulic system. A pressure transducer added to the master cylinder provides a voltage control signal. A solenoid valve added to the hydraulic circuit for the front service brakes, activated by the hybrid control system, may be closed during regenerative braking to trap the front hydraulic brake pressure, thereby enhancing energy recovery by regeneration. The flywheel clutch is closed to begin regeneration.
