    Abstract: Crawl operations for four-wheel steering vehicles are described herein. An example vehicle described herein includes four wheels, a front steering actuator to turn the front wheels, a rear steering actuator to turn the rear wheels, a front drive motor to drive the front wheels, and a rear drive motor to drive the rear wheels. The vehicle also includes an electronic control unit (ECU) to activate the front steering actuator to turn the front wheels in a first direction, activate the rear steering actuator to turn the rear wheels in a second direction opposite the first direction such that the front wheels and the rear wheels are turned in opposite directions, activate the front drive motor to drive the front wheels in a reverse direction, and activate the rear drive motor to drive the rear wheels in a forward direction while the front wheels are driven in the reverse direction.

    Abstract: The disclosure generally pertains to systems and methods for assigning alternative energy vehicles to travel routes based on vehicle wear-and-tear ratings. Wear-and-tear ratings may be influenced by factors such as, for example, road grade, travel speed, electric motor use, and battery use, on various travel routes. An example method for determining a wear-and-tear rating of an alternative energy vehicle may involve determining an amount of stress imposed upon an electric motor of an alternative energy vehicle due to a grade of a road on a travel route, and an amount of energy consumed from a battery of the alternative energy vehicle due to a speed of travel on the travel route. The wear-and-tear rating of the alternative energy vehicle may then be determined based on the amount of stress imposed upon the electric motor and/or the amount of energy consumed from the battery on the travel route.
