Heavy Duty Trucking, January 2021

HDT JANUARY 2021 14 WWW TRUCKINGINFO COM Hotline TRUCKINGS MOST RESPECTED BUSINESS REPORT technology for commercial vehicles called Evasive Maneuver Assist EMA leveraged the capabilities of Wabcos OnGuardActive radar only collision mitigation system its electronic braking system advanced emergency braking system electronic stability control and vehicle dynamics control systems with ZFs electro hydraulic ReAx power steering system In electrification ZF has a full range of electric drivelines shifting strategies and energy recuperation but recovering energy during braking depends on the right tuning between the electric motor and the foundation brakes Thats where Wabcos braking expertise comes in Mohr explained ZF has been demonstrating several advanced technologies where the ZF Wabco synergies are put to use Advanced Reversing Assist Uses cameras and radars combined with trailer brakes pedestrian detection and active braking system to help the driver in tractor trailer reversing maneuvers Automated Coupling Assist Take reversing assist to the next level and you get the industrys first fully automated coupling assist system for a heavy duty tractor trailer combination It can cut coupling time in half ZF said while increasing safety and helping less experienced drivers Adopt Control Building still further on this technology is Autonomous Driving Open Platform Technology or Adopt which provides intelligent autonomous vehicle chassis control This is designed to help autonomous driving systems from the likes of Waymo or TuSimple contend with hard to detect situations such as wet roads or oil on the road ETrailer Adding an electric motor to a trailer axle can be used in several ways including turning the whole tractor trailer combination into a hybrid using it to power refrigeration systems or adding additional performance to a fully electrified tractor Because they rely heavily on high tech trailers most of these technologies will be seen in Europe before North America What we will see soon in addition to the PowerLine transmission is ZFs ReAx steering with lane keeping functionality to be launched in 2021 with a yet to beannounced truck maker ZF is also working on next generation full electric steering targeted for 2024 This will help in developing future Level 4 autonomous vehicles but it also helps improve fuel consumption which helps optimize electrically driven vehicles In addition ZF has been working with Daimler Trucks North America on its eCascadia field testing Mohr explained that the electric drive motors currently being used are adapted from ZFs bus experience but the next generation is in preparation We are working to have a complete portfolio of central and axle electric drives from medium to heavy duty Deborah Lockridge On the tractor side the ZF Wabco acquisition brought together a lot of complementary expertise For instance Wabcos brake and stability control solutions dovetail with ZFs steering systems in ways that will help make autonomous trucks possible The Wabco acquisition brought a host of trailer technology to ZF including foundation brakes aerodynamic solutions suspension control stability control and trailer telematics PHOTO ZF
