Parking assist system

Customizable 3D surround view

Renesas and Cogent Embedded cooperate in developing a parking system based on the R-Car V3M system-on-chip. The hardware platform features two CAN FD ports.

The announced 3D surround view solution is intended to assist drivers during parking or low-peed maneuvers. The system was designed for parking assist systems in entry- and mid-level cars. It combines the Renesas R-Car V3M system-on-chip (SoC), which incorporates a dedicated image-rendering unit (IMR) that delivers 360-degree surround view, with Cogent’s software on a reference board. The jointly developed system eliminates the need to use a dedicated GPU. On-demand customization services can also be provided by Cogent to enable system developers to concentrate on developing application software to differentiate their systems. The hardware platform by the Japanese chipmaker provides two CAN FD interfaces to connect it to the in-vehicle networks.

“As in-vehicle infotainment and ADAS systems converge, automotive system designers require technologies that deliver predictable performance for safety while securing the flexibility to customize,” said Shinichi Yoshioka from Renesas. “Renesas is expanding its relationship with software expert Cogent Embedded to deliver new solutions that address both of these growing markets with our R-Car V3M SoC that delivers 3D function and performance comparable to other surround view SoCs, at lower power and cost levels.”

“We are excited about the opportunity our cooperation with Renesas provides. The R-Car V3M SoC provides the right set of functions for entry-to-mid level surround view to run efficiently our state of the art 3D surround view with pedestrian detection, cross-traffic-alert and lane tracking algorithms, an ideal combination of surround view and computer vision features,” said Artemi Ivanov, President of Cogent Embedded.

It is necessary for next-generation 3D surround view systems to achieve not only display functionality but also object recognition. Surround view is a vehicle camera system that provides an all-round panorama view and assists the driver when parking. A control display on the vehicle’s interior control panels shows data from surround view cameras and offers the driver a realistic 360-degree surround view to assist in maneuvering the vehicle to park and to alert the driver to obstacles in its path that may not be immediately visible.

The R-Car V3M is equipped with an integrated image signal processor (ISP), the IMR for low-power image rendering and the IMP-X5 computer vision engine. It features functional safety and high-performance at low-power consumption required for use in smart camera applications, surround view systems, and lidars, including NCAP (New Car Assessment Program) features.
