Scania range to incorporate Electrically Assisted Steering

The operation of heavy-duty trucks requires skill and care to avoid disaster. Customers and manufacturers alike want to have their trucks delivered with a myriad of driver support systems to make operation of the machine safer, more controlled, and more enjoyable. This creates value in supply chains and creates confidence in the automotive brand. With this in mind, Scania are introducing EAS (Electrically Assisted Steering) as an option on their trucks. According to Scania, the electrically assisted steering will enhance the driving experience and enable new or improved driver support systems. The EAS-based ADAS (Advanced Driver Assist System) functions are active at speeds above 60 km/h, although drivers must still keep their hands on the steering wheel. This is an example of active driver assistance which makes operation of the vehicle safer for both the driver and other road-users

“EAS and the support systems should be exactly that, supportive,” said Stefan Dorski, Senior Vice President and Head of Scania Trucks. “We have no intention to take away our renowned road-handling capabilities or the great feel of driving a Scania. Additionally, it is important to understand that the driver is still responsible and in command, despite the comfort and safety functions.”

The introduction of EAS has made the following possible in the Scania truck range:

LKA – Lane Keep Assist

LKA constantly monitors the lane markings to keep the vehicle centered in the lane by utilizing active steering. LKA provides support when it is activated and the activation conditions (speed of at least 60 km/h) are met.

LDW AS – Lane Departure Warning with Active Steering

This is an extension to the standard LDW function. It not only detects potential lane departures but also intervenes by steering the vehicle back into the lane. Intended lane changes, when the driver makes use of the direction indicator lamp, are not affected.

LCP – Lane Change Collision Prevention

LCP works together with Scania’s Blind Spot Warning (BSW) system to avoid lane change incidents. When BSW triggers its most intense warning, for example by detecting another vehicle, LCP uses active steering to stop the lane change (even if the direction indicator lamps are activated) and bring the truck back to its former lane. “EAS brings more capabilities than you might first think of,” said Dorski. “Not only does it add comfort and relief for all kinds of normal driving, but it can also help mitigate incidents. The ADAS features help by taking out some of the concrete stress factors, such as blind spots, which is highly beneficial for truck drivers.”

Auto Trendy’s take:

Scania trucks are taking a step in the right direction with the introduction of this active system. They are clearly focusing on road safety and the enhancement of the driver experience. ADAS systems continue to evolve and the technology behind them is both fascinating to tech enthusiasts and critically beneficial to the automotive industry and to society at large. We at Auto Trendy are always excited to see the implementation of these new life-saving technologies.
