CONTROLLERLESS ELECTRIC DRIVE SYSTEM
First Claim
1. In an automotive system comprising one or more powered wheels, a controllerless electric drive system configured to power the one or more powered wheels, the system comprising:
- a battery;
a substantially constant-speed electric motor;
an infinitely variable transmission; and
one or more powered wheels, wherein the battery is coupled to the substantially constant-speed electric motor, and wherein the substantially constant-speed electric motor is coupled to the infinitely variable transmission, such that the battery provides power for the electric motor to drive the infinitely variable transmission which turns the one or more powered wheels, without implementing a controller to vary the current between the battery and the motor.

Abstract
Embodiments described herein are directed to a controllerless electric drive system, a controllerless hybrid drive system and a method for controlling drive system characteristics based on received drive system inputs. In one instance, a controllerless electric drive system is configured to power one or more powered wheels. The controllerless electric drive system includes a battery, a substantially constant-speed electric motor, an infinitely variable transmission and one or more powered wheels. The battery is coupled to the substantially constant-speed electric motor, and the motor is coupled to the infinitely variable transmission. As such, the battery provides power for the electric motor to drive the infinitely variable transmission which turns the one or more powered wheels, without implementing a controller to vary the current or voltage between the battery and the motor.

15. At a computing device, a method for controlling drive system characteristics based on one or more received drive system inputs, the drive system including at least a motor and an infinitely variable transmission (IVT), the method comprising:
-
an act of receiving one or more inputs from a vehicle user indicating that at least one of an acceleration rate and a deceleration rate is to be adjusted, the acceleration and deceleration rates being adjustable using an actuator configured to vary the rpm of the output shaft of the IVT; an act of determining, based on the received inputs, the degree to which the acceleration rate or the deceleration rate is to be adjusted; and an act of adjusting at least one of the acceleration rate and the deceleration rate by varying the rpm of the output shaft of the IVT using the actuator. - View Dependent Claims (16, 17, 18, 19, 20)
