Abstract
Disclosed herein are vehicle control devices and methods including a signal processor responsive to a signal proportional to dynamo speed and a second signal proportional to desired torque. The signal processor provides a control signal for suitable armature voltage control means which controls the armature voltage so as to adjust dynamo torque with respect to the desired torque signal. The signal processor further in response to the dynamo speed signal and in response to a signal proportional to brake pedal position provides a control signal to chopper means for adjusting the power generated by the dynamos in response to the brake pedal position. The signal processor further controls the dynamo field with respect to dynamo torque and speed so as to maximize dynamo operating efficiency. Various related devices and methods are also disclosed.
