A driver’s most often utilized instrument is the steering wheel. It is used to steer the vehicle, but it also serves as an extension of the sense of touch.
The driver can feel the motion of the car, the road surface, and forces from the surroundings by gripping the steering wheel.
However, recent developments in steering system technology demonstrate that it is feasible to augment what is perceived in the steering wheel, therefore potentially assisting the driver. The true problem in this is the efficacy of the design, which rests in being cooperative with the human driver.
Increased electronic content in light-duty vehicles allows for the use of sophisticated steering systems. Vehicle electrification includes powertrain, infotainment, linked cars, safety systems, and electronics.
From classic manual steering and HPS, automotive steering systems have evolved into EPS and EHPS. Demand-side cost pressure is increasing on steering system makers.
Commercial-vehicle component makers and suppliers are currently confronting problems in maintaining quality while keeping costs down.
As a result, steering system manufacturers are trying to develop development strategies in order to remain profitable in this competitive market. OEM competition is fierce, and prices are rising.
In the most recent truck generation, technological innovation permitted a significant reduction in pollutants and increased fuel efficiency (through new engines, tyres, lighter materials, and so on).
Euro 6 applies to new trucks, not the previous Euro classes, which are less efficient and pollute the environment. There is also no assurance that the earlier Euro criteria will be met in the long run.
With Euro 6, this is required, however expertise with the most recent standards is obviously limited. Because of the rate of truck fleet turnover, it may take at least a decade to have a meaningful influence on the truck fleet utilizing key highways. However, truck emissions in cities continue to be a major issue.

When compared to a vehicle, the power required to steer a truck is quite significant. This is evident when one considers the relative difference in front axle weight, with a normal vehicle carrying 750 kg and most big trucks carrying up to 7,500 kg.
A hydraulic steering gear is the most typical front axle steering system for a large vehicle. A hydraulic steering gear offers a lot of power for its size. In general, rear drive axles are not guided.
However, steering is frequently found on other rear axles. The steering principles of these axles are frequently basic, with the goal of avoiding tyre wear or shortening the effective wheelbase. The rear axle steering affects vehicle responsiveness and maneuverability.
Steering system advancements have increased the safety of heavy-duty vehicles and are causing more OEMs to embrace the systems. As a result of these advances, the markets for heavy-duty vehicle steering systems are expanding.
Growing environmental concerns, such as air pollution, have prompted the development of strict rules for the automobile sector. The bulk of restrictions are aimed at medium and heavy-duty trucks, which contribute considerably to CO2 emissions while having smaller volumes than passenger vehicles and LCVs.
The market for medium and heavy-duty truck steering systems is highly concentrated, with intense rivalry among medium and heavy-duty truck steering system manufacturers.
Because the EPS system takes power from the battery, it is more fuel-efficient and dependable than HPS systems. Increased load-bearing capability would guarantee that this technology be used in commercial vehicles as well.
Volvo, for example, has created Volvo Dynamic Steering, which is driven by an electric motor. The steering is controlled by the motor 2,000 times per second. This technology was created using a ‘Torque Overlay’ platform.
Nexteer Automotive has also created a rack-assisted electric power steering system for pickup trucks. Robert Bosch, another prominent steering system maker, has launched the Servo twin electro-hydraulic steering system for large commercial vehicles.
The Europe Truck Steering Market can be segmented into following categories for further analysis.
Internet of Technology has been integrated into the systems of enhancement for the trucks moving across in Europe. The Internet of Things (IoT) is a network of gadgets, vehicles, and appliances that can actively communicate data.
Networks of sensors installed throughout the vehicle, for example, may monitor anything from tyre pressure to load stability. Truck systems that are semi-autonomous or platooned. This will result in even more data for carriers and shippers to handle and make choices with.
With larger cars such as full-sized trucks and SUVs leading the pack in terms of new vehicle sales, automakers want an EPS system that can handle bigger weights in order to deliver ADAS and enhanced safety features on their most popular vehicles.
Rack-assist electric power steering (REPS) is intended for larger cars in order to manage higher front-axle loads while maximizing packing space.
REPS also allows these larger cars to benefit from all of the advanced safety and performance features provided by EPS technology, including lane keeping, park assist, traffic jam assist, lane departure warning, and more. REPS systems are also crucial in Europe’s automakers’ shift to e-mobility.
Because of the additional weight of batteries in electric trucks, automakers are increasingly turning to our High-Output (HO) REPS systems, which almost quadruple the steering load capabilities of regular REPS.
In comparison to a normal REPS system, our High-Output REPS system can steer up to 24 kilonewtons (kN). REPS systems are also assisting manufacturers in ensuring that their cars retain the branded steering feel that customers have come to know and expect from that OEM during the transition to EVs.
REPS systems are at the core of heavier vehicles’ personality and performance, whether it’s ensuring an electric truck still feels like a truck or delivering a sporty steering feel in performance automobiles.
Several companies have developed and implemented camera monitor systems to provide the drivers with additional FOV. These systems can range from simple rear or front view cameras to 360 degrees bird view images to facilitate drivers’ awareness of the surroundings.
Continental, Volkswagen, and Stoneridge have developed concepts for digital rear-view mirrors with displays mounted inside the truck cab.
UD Trucks has most recently brought in the latest steering system technology within the global market including the European market of requirements. To provide additional torque when needed, UD Active Steering includes an electric motor placed above the hydraulic steering gear.
The electronic control unit (ECU) installed on the electric motor gets information from sensors throughout the vehicle 2,000 times per second, monitoring the driving environment as well as the driver’s own actions.
This system management provides adequate torque to the steering wheel weight, resulting in accurate and steady steering regardless of speed, payload, or road conditions. The simplicity and accuracy of steering contributes to reduced driver fatigue and safer roadways.
Independent studies were undertaken by UD Trucks to evaluate and compare driver tiredness in trucks equipped with and without UD Active Steering. An electroencephalogram (EEG) was utilised to assess driver attention and tension, while an electromyogram (EMG) was employed to assess muscular effort.
Volvo Trucks Group has brought in the latest Electric based truck propulsion system, which is focused on better levels of emission and efficiency control.
Volvo Trucks is currently testing the electric heavy-duty Volvo FH, Volvo FM, and Volvo FMX trucks, which will be utilised for regional transportation and urban development throughout Europe.
Volvo Dynamic Steering features an electric motor mounted on top of the hydraulic steering gear. Input from multiple vehicle sensors continuously monitors drivers’ actions, environmental factors and road conditions more than 2,000 times per second.
The system provides up to nine pound-feet of torque in the steering column. It features a return-to-center function for the wheel when the truck is in motion. That makes reversing and maneuvering in tight areas easier.
ZF Friedrichshafen offers a version of a light-touch steering system called ReAX. Robert Bosch will equip Nikola Motors’ fuel cell-powered Class 8 trucks with its Servo Twin electro-hydraulic steering system early in the next decade.
All three systems enable future automated driving, including lane keeping and centering. Daimler Trucks North America is producing the 2020 Freightliner Cascadia that includes Level 2 partial automation features.
