UPS said its venture capital arm, UPS Ventures, has made a minority investment in autonomous driving company TuSimple. Together, both companies are testing self-driving tractor trailers on a route in Arizona to determine whether the vehicles can improve service and efficiency in the UPS network. This is an extension of the ongoing commercial relationship between UPS and TuSimple in which UPS has purchased transportation services from TuSimple.

The work with autonomous driving company TuSimple began with the goal of helping UPS better understand the requirements for Level 4 Autonomous trucking in its network. L4 Autonomous means the vehicle’s onboard computer is in complete control at all times, eliminating manual intervention. Currently, however, laws regulating L4 Autonomous driving require a driver in the vehicle at all times to take over operation if needed.

Throughout the ongoing tests, UPS has been providing truckloads of goods for TuSimple to carry on a North American Freight Forwarding route between Phoenix and Tucson, Arizona. The company initiated self-driving service in May, 2019, with a driver and engineer in the vehicle. TuSimple and UPS monitor distance and time the trucks travel autonomously, safety data and transport time.

Founded in 2015, TuSimple’s mission is to bring the first self-driving truck to market, to increase safety, decrease transportation costs and reduce carbon emissions. TuSimple develops technology that will allow shipping companies to operate self-driving class 8 tractor-trailers – those that exceed 33,000 pounds and typically have three or more axles.
