1. A refuse vehicle comprising:
a drive motor configured to operate according to (i) a drive mode wherein the drive motor consumes electrical energy to drive a tractive element to transport the refuse vehicle, or (ii) a regenerative braking mode wherein the drive motor is driven by the tractive element to generate electrical energy and provide regenerative braking;
a battery configured to provide the electrical energy to the drive motor for transportation and receive electrical energy from the drive motor and charge using the electrical energy during regenerative braking of the refuse vehicle;
a pedal configured to be depressed by an operator of the refuse vehicle, wherein depression of the pedal across a first range of positions causes the drive motor to operate according to the drive mode to drive the tractive element for transportation, and depression of the pedal across a second range of positions causes the drive motor to operate according to the regenerative braking mode to be driven by the tractive element for generation of electrical energy and regenerative braking; and
processing circuitry configured to:
compare an amount of depression of the pedal to a transition point;
in response to the amount of depression of the pedal exceeding the transition point by at least a deadband amount, use a linear relationship and the amount of depression of the pedal to determine a requested amount of acceleration and operate the drive motor according to the drive mode to provide the requested amount of acceleration for transportation.
