WABCO and ZF demonstrate prototype of Evasive Maneuver Assist for commercial vehicles; connecting active braking and steering capability
WABCO Holdings and ZF have developed and demonstrated a prototype of a new collision avoidance technology for commercial vehicles. The Evasive Maneuver Assist (EMA) combines WABCO’s world-class braking, stability and vehicle dynamics control systems on trucks and trailers with ZF’s active steering technology—an industry first. EMA marks another step toward enabling autonomous driving in the commercial vehicle industry.
Evasive Maneuver Assist leverages the capabilities of WABCO’s OnGuardACTIVE, its 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 Maneuver 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.
Based on the core competencies of WABCO and ZF systems, Evasive Maneuver 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.
OnGuardACTIVE uses a 77GHz radar sensor that maintains the system’s high performance in all weather conditions. Its superior performance is particularly vital in poor visibility situations such as white outs, heavy rain, dense fog, blinding sunshine or night time driving when camera-based sensors used on other collision mitigation systems may be impaired.
OnGuardACTIVE’s radar offers up to five times higher bandwidth than 24GHz radar-based collision mitigation systems available in the market. The system’s dual mode function addresses both long range and adjacent lane views. This enables higher accuracy in object detection, and a more than 30% longer range than alternative systems. OnGuardACTIVE is capable of analyzing traffic up to 650 feet ahead, thus recognizing impending critical driving situations earlier.
WABCO and ZF demonstrated Evasive Maneuver Assist for the first time at the test track of RWTH Aachen University in Aldenhoven, Germany.
