MOTOR VEHICLE POWER MANAGEMENT SYSTEM AND METHOD
First Claim
1. A power management system for a vehicle having at least one motor, comprising:
- a user interface for receiving a desired destination;
a global positioning system input for receiving the instant geographical position of the vehicle;
an energy management system input for receiving information regarding the energy reserves of the vehicle;
a motor controller operatively connected to the at least one motor; and
a power controller operatively connected to the user interface, the global positioning system input, the energy management system input and the motor controller, the power controller being configured to compute a maximum available power estimate based on the desired destination, the instant geographical position of the vehicle and the information regarding the energy reserves of the vehicle;
wherein the power controller limits power available to the at least one motor though the motor controller based on the maximum available power estimate.

Abstract
A power management system for a vehicle having at least one motor, comprising a user interface, a global positioning system input, an energy management system input, a motor controller operatively connected to the at least one motor and a power controller operatively connected to the user interface, the global positioning system input, the energy management system input and the motor controller, the power controller being configured to estimate a maximum available power value based on information provided by the user interface, the global positioning system input and the energy management system input. The power controller limits power available to the motor though the motor controller based on the estimated maximum available power.
