Hybrid Vehicle Having Multi-Mode Controller
First Claim
1. A control system for controlling operating modes of a hybrid vehicle, the vehicle having an internal combustion engine, a first electric motor-generator, an electric traction motor, and battery pack, the control system comprising:
- a vehicle controller operative to;
receive a gear mode indicator, an electric-only power mode indicator, and a present battery storage capacity;
compare the present battery storage capacity with a battery threshold;
select an operating mode based on the gear-mode indicator, the electric-only power mode indicator, and a result of the comparison; and
output a selected operating mode to control the engine, the first electric motor-generator, and the electric traction motor, so that the vehicle operates according to the selected mode.

Abstract
A control system for a hybrid vehicle controls the various operating modes of the hybrid vehicle. Operating modes of the hybrid vehicle include an electric-only power mode, a series hybrid mode, a series hybrid dual-power mode, and a parallel hybrid tri-power mode. The control system selects one of the operating modes for the hybrid vehicle based on one or more inputs and comparisons. Examples of inputs for the control system include a gear-mode, a present battery storage capacity, a present velocity of the hybrid vehicle, and the previous operating mode of the hybrid power system. The control system may also take into account whether a user has selected the electric-only power mode. The control system may also control the operations of one or more components of the hybrid vehicle while operating in one of the operating modes.
