Vehicle control technology enables auto evasive manoeuvres

Evasive manoeuvre assist technology

Collision avoidance and steering control technology combination results in Evasive Manoeuvre Assistance for autonomous control of commercial vehicles.

WABCO has demonstrated the prototype of a breakthrough collision avoidance technology for commercial vehicles. Jointly developed by WABCO and ZF, the Evasive Manoeuvre Assist (EMA) combines WABCO’s braking, stability and vehicle dynamics control systems on trucks and trailers with ZF’s top active steering technology – an industry first. EMA marks yet another critical step toward enabling autonomous driving in the commercial vehicle industry.

Evasive Manoeuvre Assist uses the capabilities of WABCO’s OnGuardACTIVE, its most advanced, radar-only collision mitigation system. A radar sensor identifies moving or stationary vehicles ahead and alerts the driver via visual, audio and haptic signals of impending rear-end collisions. Should the driver determine that the system cannot avoid a rear-end collision by driver-initiated or autonomous braking alone, Evasive Manoeuvre Assist engages to help the driver to safely steer around an obstructing vehicle and to bring truck and trailer to a complete and safe stop. In such situations, this new collision avoidance function is connecting WABCO’s proven electronic braking system (EBS), advanced emergency braking system (AEBS), electronic stability control (ESC) and vehicle dynamics control systems to ZF’s electrohydraulic ReAX power steering system.

Evasive Manoeuvre Assist controls both the longitudinal and lateral movements of heavy-duty trucks and trailers in challenging driving situations at high-speed, thereby helping to avoid rear-end collisions. Critical driving situations may include traffic jams that appear suddenly after curves or when driving on wet, low friction road surfaces.

“Today’s Evasive Manoeuvre Assist prototype demonstration is a powerful example of WABCO’s and ZF’s abilities in developing advanced safety technology for commercial vehicles,” said Jacques Esculier, Chairman and Chief Executive Officer, WABCO, “Evasive Manoeuvre Assist connects WABCO’s braking and stability control systems with ZF’s active steering system for the first time and marks an important step toward realising the transportindustry’s vision of autonomous driving.”

“I’m excited that ZF and WABCO joined forces to combine their steering and braking technologies to create a new collision avoidance function for commercial vehicles,” said Dr Stefan Sommer, Chief Executive Officer, ZF Friedrichshafen AG. “Evasive Manoeuvre Assist is yet another innovation that has the potential to significantly advance commercial vehicle and road safety worldwide.”

WABCO and ZF demonstrated Evasive Manoeuvre Assist for the very first time at the test track of RWTH Aachen University in Aldenhoven, Germany.
