Stabilized electric distribution system for use with a vehicle having electric assist

This invention describes a control method for hybrid vehicles that use an electric motor for traction assist. It manages the flow of electricity between the electric assist components, like an ultracapacitor and motor/generator, and the vehicle's standard accessory power system. The core idea is to regulate the accessory power voltage, protecting it from fluctuations caused by the electric assist system, particularly during vehicle startup and when the electric motor is actively assisting.

Why it matters: Filed when hybrid vehicle technology was still maturing, this control method for voltage stability is more relevant today due to the widespread adoption of vehicle electrification. Modern embedded systems and advanced power electronics now offer significantly more robust and cost-effective platforms for implementing such sophisticated energy management controllers.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
