Delphi’s integrated RACam (RAdar Camera) system will be introduced on the new Volvo SPA platform at the end of 2014. The system incorporates radar sensing, vision sensing and data fusion into a single module to enable a suite of active safety systems including full speed range adaptive cruise control; adaptive headlamp control; traffic sign recognition; forward collision warning; pedestrian detection; and autonomous braking.

At RACam’s core is Delphi’s electronically scanning radar. ESR makes it possible to provide mid- and long-range sensing with a single radar.
RACam’s design resulted in a module small enough to be positioned on the windscreen side of the rear view mirror (see image right). Although separate radar systems are traditionally mounted behind the vehicle’s front grille, RACam’s size makes it possible to locate the radar away from crush zone, helping to reduce repair costs following a frontal impact.
As a long-time partner with Volvo, Delphi supplied sensors to Volvo Car Group which was the only participating car manufacturer in the SARTRE (Safe Road Trains for the Environment) project, which was successfully completed in 2012. The SARTRE road train included a lead truck followed by three Volvo cars (S60, V60 and XC60) driven autonomously at speeds of up to 90 km/h (56 mph).
Delphi also is part of Non Hit Car and Truck project, a Swedish national research program in which Volvo Trucks and Volvo Car Group are developing next generation active safety and automated driving features.
Not only does this integrated sensor fusion system offer drivers an impressive bundle of advanced safety functionalities in their vehicles and help OEMs including Volvo meet new Euro NCAP 5-star ratings, it is also intelligently engineered to be significantly less expensive, lighter and smaller than non-integrated systems to benefit the OEM’s overall vehicle design.—Jugal Vijayvargiya, president, Electronics & Safety, Delphi
