WPG World Peace launches ADAS domain controller solution based on NXP

On October 22, 2019, WPG Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market , announced that its subsidiary WPI has launched an ADAS domain controller system solution based on NXP S32V234 + MPC5744P.

Traditional cars use a distributed electrical and electronic architecture, and the various ECUs in the car are connected together through CAN or LIN buses. Now the number of ECUs in cars has increased to dozens or even hundreds, and the distributed architecture is therefore facing challenges. With the advent of the era of autonomous driving , the perception, control, and decision-making systems involved in car driving are becoming more and more complex, and the information interaction and control between systems are also increasing. All parties hope that it can become a modular , portable, and easy-to-manage automotive subsystem, and the concept of automotive domain controller DCU has therefore been proposed. According to different functions, the automotive network architecture can be divided into body domain, power domain, chassis domain, ADAS domain, external network domain, and infotainment domain.

As an important component of future smart cars, ADAS domain controllers have functions such as multi -sensor fusion, positioning, path planning, decision control, wireless communication, and high-speed communication. They can flexibly configure and adjust the required functions according to customer requirements, and facilitate platform-based and modular production and manufacturing . Vehicle manufacturers can integrate platforms with similar structures across platforms, which not only facilitates production, but also increases the protection of information security, killing two birds with one stone for vehicle manufacturers.

The ADAS domain controller solution based on NXP S32V234 + MPC5744P launched by WPG World Peace requires the use of a powerful core processor to control most of the functions originally belonging to each ECU in the domain, thereby replacing the traditional distributed architecture. The S32V234 used in this solution is a core processor designed for safe computing-intensive applications in the field of vision and sensor fusion, with a quad-core Cor te x-A53 + Cortex-M4 processor, two APEX-2 vision accelerators, 3D  GPU , and built-in ISP.

ADAS domain controller meets the safety function level requirements of automobiles. The SIP ADAS domain controller solution baseboard uses the MCU  MPC5744P that meets the ISO-26262 ASIL requirements. It can manage and monitor the system power supply and handle system functional failures in real time, making the entire system reach ASIL-D level.

Core technology advantages

S32V234 has super processing power, Cortex-M4 + 4-core Cortex-A53, main frequency reaches 1GHz, including GPU, APEX 2 professional image acceleration processing unit, which can meet the visual application needs of different fields such as automobile, industry and consumer;

Built-in ISP image signal processing module, supporting up to 8-way camera image input simultaneously;

The MPC574xP series of automotive-grade MCUs is the industry's first automotive-grade MCU to achieve functional safety ISO-26262 ASIL-D Qualification certification , a new generation of the MPC5643L.

Connect related sensors or modules, such as ultrasonic sensors for parking assistance, and report status to the gateway (eg HDC2080 is to simulate sensor reading);

Software update: Update the software of ADAS domain controller through vehicle communication protocol;

Functional safety: strictly monitor the power management of the ADAS domain controller and handle system dysfunctions accordingly. Even if a system operation error occurs, the ADAS domain control function can still be maintained within the normal operating range, reducing the damage caused by system failures.

ADAS-related intelligent driving functions are concentrated into DCU, and connected to the central gateway through a variety of interfaces such as Ethernet and CAN bus for information exchange and functional operations.
