Autonomous Waste Collection Truck

Номер: US20210024068A1
Принадлежит: Robotic Research, LLC

Waste collection is performed at regular intervals around the world. The process currently is performed by a team consisting of a waste collection truck that carries the refuse that is driven around urban areas at slow speeds. This waste collection truck usually contains a large opening in the back. A team of humans controls this truck and collects the bins dumping the refuse on the back of the truck and returning the bins to the curb. Usually, the driver (human) of the truck positions the truck so as to minimize the distance that the human garbage collectors need to walk with the loaded bins, and slowly drives a route that take the truck to the collections sites. Because currently most residential neighborhoods and some commercial neighborhoods do not use bins and pick up locations that are easy to automatically lift, it is likely that the process of picking up the bins, depositing the refuse on the truck, and returning the bins to the curb will be performed by humans for some time to come. However, the driver of the truck and the control mechanism to make sure that the truck minimizes the work performed by the humans picking up the bins, can be readily and economically performed using current technology. The invention being presented here automates the functions of the driver of the garbage truck. It involves a waste collection truck designed to follow routes to collect waste using a human to pick up the bins with refuse or other material comprising a truck that includes a drive-by-wire kit, a database storing the collection routes, a mechanism for detecting the position of the human which collects the waste bins and empties them on the back of the truck and a control mechanism that follows the assigned route and speeds or slows down the truck as to minimize the distance that the human will need to walk to empty the trash in the back of the waste collection truck. In addition, robots will replace the human workers who empty the bins. 1. An autonomous waste ...

The method comprises: obtaining an initial torque limit from a torque limit profile providing operating constraints that fall within the primary operating constraints. The method further comprises: implementing a torque limit that corresponds to the initial torque limit value such that in an event that a torque demand exceeds the torque limit then the engine speed will drop below the desired engine speed. The method further comprises, in an event that torque converter speed ratio between engine and ground propulsion drops below a speed ratio threshold, removing the torque limit profile and reverting to primary operating constraints.
