Freescale Radar chipset makes ADAS more affordable

June 25, 2013 // By Christoph Hammerschmidt
In the automated driving scenarios of the future and in many other safety-oriented advanced driver assistance systems (ADAS), Radar is one of the central sensor technologies. Chipmaker Freescale now has introduced a comprehensive system-level solution for automotive radar based advanced driver assistance systems. The new Qorivva MPC577xK microcontroller (MCU) and MRD2001 77 GHz radar transceiver chipset provide the embedded technology necessary for affordable radar based ADAS solutions with fewer components, helping increase the adoption of such features in mainstream vehicles.

The Qorivva MPC577xK MCU, built on Power Architecture technology, provides high-level digital and analog integration in a single-chip solution for radar applications, removing up to four additional major printed circuit board (PCB) components and reducing system-level cost, PCB space and software complexity. The MCU also provides high performance for intense computational tasks with key integrated digital accelerators and features a state-of-the-art signal processing toolbox that contains all of the hardware modules required for processing sampled signals from short-, medium- and long-range radar applications.

Performance data from the European New Car Assessment Programme (Euro NCAP ) suggests that safety systems, such as Autonomous Emergency Braking (AEB), can reduce accidents by up to 27% and can lead to a considerable reduction in road injuries. Euro NCAP plans to incorporate the AEB assessment for cars sold in Europe into its five star rating scheme beginning 2014.

Using Freescale's new radar transceiver chipset, automakers can implement long-range and mid-range frontal radar for adaptive cruise control and autonomous emergency braking systems, as well as manage blind spot and side-impact detection – all through a single, scalable, multi-channel solution.

Designers can pair the radar transceiver chipset with the Qorivva MCU to achieve a total system solution for both low-end and high-end radar modules. By utilizing a single, scalable solution, automakers can avoid purchasing and reconfiguring various solutions across vehicle models, saving time and material costs.

“ADAS solutions continue to proliferate and are no longer exclusive to high-end luxury vehicles. Automakers are now looking to implement these sophisticated safety features across their entire lineups and, to do so, they need more integrated, cost-optimized solutions,” said Ian Riches, Director – Global Automotive Practice, Strategy Analytics. “Freescale’s radar solution offers automakers virtually everything they need for scalable ADAS applications, as no other semiconductor or components are needed to complete the system. This will enable consumers to benefit from safer, more advanced and reliable vehicles beyond the luxury market.”
