On the ZF Know-how Day, held on Oct. 11 on the Transportation Analysis Middle outdoors of Columbus, Ohio, ZF engineers showcased its newest slate of latest business car merchandise. These included a supercharged, autonomous-based, superior driver security system and an all-electric energy steering system that the corporate feels might be the following commonplace in steering management methods for heavy-duty vehicles.
On show was ZF’s new eBeam, an electrical drive axle slated for medium-duty purposes, in addition to the newest variations of the Powerline computerized transmission.
ZF additionally launched its OnGuardMax autonomous emergency braking system. OnGuardMax is a fruits of a Wabco security management system merged with ZF’s autonomous car management applied sciences.
Based on Dan Williams, ZF’s director of ADAS and Autonomy, the system makes use of complimentary digital camera and radar sensors that are refined sufficient to detect and react to pedestrians, bicyclists and bikes.
OnGuardMax can also be designed to assist drivers handle advanced driving conditions with superior object detection and classification.
OnGuardMax may be paired with OnGuardActive, which detects transferring, stopped and stationary objects and offers visible, audible and haptic warnings. If obligatory, OnGuardActive will apply the brakes to keep away from or mitigate a ahead collision.
OnGuardActive additionally options adaptive cruise management, which tracks and displays intervals with automobiles in entrance of the truck. The system then stays a secure (3.6 seconds) following distance behind a car and routinely will regulate its chosen pace to stay that very same distance behind. The system can detect automobiles as much as 650 ft forward, and, Williams mentioned, it’s dependable anytime, together with inclement climate.
ZF’s blind spot detection system, dubbed OnSide, will also be built-in with OnGuardMax and OnGuardActive. It is a radar-based blind spot detection system that helps drivers merging into adjoining, passenger facet lanes by checking them for clearance.
OnSide prompts and alerts drivers of transferring automobiles within the blind spot at speeds of 15 mph and above, whereas the radar constantly detects all kinds of stationary and transferring objects within the car’s blind spot. The algorithm filters out the stationary objects to permit the system to warn the driving force solely of transferring objects. The system is calibrated to supply a 160-degree subject of view with attain of as much as 33 ft rearwards.
“We felt it was essential to supply these methods in order that fleets can decide and select which choices greatest match their wants,” Williams mentioned. “Each fleet has particular security wants and price range issues. However we’re assured that when they go for one system, the worth of integrating further ZF ADAS into their automobiles will turn out to be obvious in a short time.”
Electrical Energy Steering System: A Entire New Option to Steer
ZF can also be excited concerning the prospects for it’s new electrical energy steering (EPS) system, which Williams believes has the potential to fully remodel business car steering methods by transferring away from hydraulic-boosted controls to full drive-by-wire electrical steering management.
“Hydraulic energy steering is 75-year-old expertise,” Williams defined. “We predict the time has come for a brand new approach to steer business automobiles. Furthermore, we see EPS as a cornerstone expertise for the trade’s transformation in the direction of electrification, whereas offering a constructing block for subsequent technology superior driver help methods, supporting the trade’s ambitions in the direction of autonomous driving. The system is relevant to all powertrain ideas, whereas seamlessly matching the necessities of electrical business automobiles and matches to a broad vary of medium- and heavy-duty vehicles and buses.”
Williams mentioned the EPS builds off of the Reax electric-over-hydraulic steering system, which he mentioned ZF additionally thought-about a stepping-stone expertise on the trail to full digital steering management for Class 8 vehicles.
From an OEM perspective, Williams factors out hydraulic energy steering methods are advanced, heavy and maintenance-intensive.
“From a car meeting standpoint, we’re taking the necessity to put wherever from seven to 12 totally different parts – together with pumps, belts, brackets and hoses – on the car,” he explains. “From the fleet perspective, this can be a wholly secure and redundant system that may be adjusted to supply the steering management fleets need. And it’s a 100% maintenance-free system for the lifetime of the truck.”
Hydraulic energy steering methods do most of their work at decrease speeds, Williams added.
“However at freeway speeds, you’re losing horsepower to easily hold that pump spinning – whereas it’s not contributing something to manage of the truck,” he says.

That’s why Williams mentioned ZF believes EPS can be notably enticing to OEMs as the following spherical of U.S. Environmental Safety Company diesel exhaust and greenhouse fuel emissions requirements take impact in 2027.
“It’s true that you simply’re not dropping a substantial amount of parasitic horsepower loss at highways speeds,” he mentioned. “However even two or three horsepower recouped at these speeds could make a contribution to general gas financial system and emissions reductions. Furthermore, changing hydraulic steering removes waste warmth generated by the system from the engine bay whereas taking complexity and weight out of the powertrain. It’s only a extra environment friendly and maintenance-friendly strategy to business car steering.”
Williams mentioned EPS is at present slated for manufacturing someday within the 2025 – 2026 timeline.
“However, frankly,” he added, “about 10 years after that, we consider you’ll need to look lengthy and arduous to discover a new truck with hydraulic steering within the trade. There could also be a number of severe-duty fashions that retain hydraulic steering. However we predict the overwhelming majority of line-haul vehicles can be utilizing electrical steering management like EPS.”
