Abstract

This invention provides a process for determining a desired torque (load) value for a load-dependent current generating system, such as a fuel cell system, in an electric vehicle. The process calculates load based on various driver demands such as accelerator position, brake position, Key on/off, Gear selector position, and system component temperatures. Additionally, the process considers the amount of current available from the load-dependent current generating system and matches that current to the current drawn by the electric motor. The process can be applied to a direct current (DC) electric traction motor or an alternating current (AC) induction motor.

Claims (6)

1. A process for controlling an output from a load-dependent current generating system in an electric vehicle, comprising the steps of:
reading vehicle sensors to determine driver torque demand;
calculating motor current demand (load) for an electric driving motor, based on the driver torque demand;
calculating a desired current output for the load-dependent current generating system based on said desired values for motor currents demand; and calculating available current output from the load-dependent current generating system.
2. The process of claim 1 further comprising the step of matching the desired current output with the available current output.
3. The process of claim 1 wherein the vehicle sensors comprise:

sensing accelerator position;
sensing brake position;
sensing key on:
sensing gear selector position;
sensing load-dependent current generating system temperature.
4. The process of claim 1 wherein the load-dependent current generating system is a fuel cell.
5. The process of claim 1 wherein the drive motor is any electric traction motor.
6. The process of claim 1 wherein the drive motor is an alternating current induction motor.
