Abstract

A hybrid vehicle controller operates to use GPS navigation information to determine how much energy should be delivered from or sent to, the battery. The battery charge can be better managed by using knowledge of the future path of the vehicle.

Claims

1. A hybrid vehicle, comprising:

a battery;

a motor, operating from power stored in said battery;

a GPS navigator, that allows determination of future trip information;

a controller, including a monitoring port, which monitors a state of charge of the battery, and also receives information from said GPS navigator, and controls how much energy is received by and delivered by said battery, based on both of said state of charge of said battery, and said information.

2. A vehicle as in claim 1, wherein said controller determines a contour of a road ahead that will be traveled, based on said information, and uses said contour to determine an amount of charge to be delivered.

3. A vehicle as in claim 1, further comprising a catalytic converter, and said controller detects a temperature of said catalytic converter, and uses said temperature to determine energy delivery by said battery.
