The current vigorous development of new energy automotive products, in order to help customers quickly build to meet the vehicle controller Autosar and functional safety requirements, shorten customer development time, Shanghai Industrial Control Security Innovation Technology Co., Ltd. jointly owned enterprise Shanghai studio leather Road Electronic Technology Ltd., has developed a reference design of VCU. For the overall program controller of the vehicle, the car-based regulatory level MCU SPC574K72 PowerPC architecture as the core complemented by a highly integrated U-chip L9788 chip, to help customers quickly build a vehicle control system.
Hardware resources, in addition to the U-chip and the MCU, further comprising a multi-channel HSD / LSD output L9301 (SPI interface 12 can be arranged low side drive path) and L9305 (4-way high-precision current control can be high and low side driver configuration) , a brushed DC motor driver IC L9960T, see below.
Figure1 GPF1 VCU Reference Board
Software service that provides a complete reference design based on Autosar:
• SPC574 MCAL, Version 0.9.0
• Complete BSW programs and third-party integration of ETAS RTA
• complex drive for complete Autosar L9788, L9960, L9305, L9301 and other CDD
• basis for Matlab Simulink of ASW application layer model,
• for the a Sample commissioning non Autosar demo program source code;
development tool chains:
• ST can provide free SPC5 Studio environment
• customers can also choose tools business to pay, such as Tasking / Hightec and other BSW / ASW compiler tool chain, PLS UDE / Lauterbach and other debugging emulator, as well as the environment Autosar
The figure is based on a demonstration of the reference solutions:

Based on the complexity of the device driver software Component, leather road safety control, joint TUV NORD, were functional safety assessment of the software components (Function Safety Assessment), 5.24 started Kick Off Meeting. Including on the following topics in-depth communication:
(1) L9788 Complex Device Driver Software Arch
(2) L9788 CDD Function Safety Assessment List
(3) L9788 CDD Function Safety Assessment Plan
specific issues the two sides to assess and review conducted in-depth exchanges.
[Shanghai Shanghai control security is to create a global technology innovation center, one of the first to promote the development of the construction and transformation of functional platform, to build the Shanghai Municipal Government and the Putuo District government levels linkage. Platform chaired by ××× He Jifeng Fellow, Chief Scientist, based in Shanghai, the Yangtze River Delta region to play industrial advantages, for automotive, rail, aerospace and other key state industries and critical information infrastructure, industrial control systems and information security core functions technology development and achievements, and joint upstream and downstream enterprises to provide technical research and development, standards development, simulation, monitoring and early warning, detection and evaluation, training, consulting, intellectual property, industry, docking and other services to help customers improve the industrial manufacturing and end-product life safe and reliable cycle, as well as strengthening information security industry and the internet of things, and research to create a connection "security +" eco-industry service platform with related subjects such as political capital. ]
