At the 2020 China Automotive Forum held on August 13 - 15, Huawei Intelligent Vehicle BU CTO Cai Jianyong gave a detailed answer on Huawei VehicleStack digital system architecture in his presentation.
Cai Jianyong believes that in 5-10 years, intelligent driving will be the focus of competition, and the intelligent cabin will become the focus of differentiation for manufacturers.
He believes that the shape of the car and the usage scenarios of the car will change dramatically, and the experience inside the car will become very rich and very diverse. Therefore, all of Huawei's smart car solutions have taken into account possible future needs.
Huawei is building a digital system through CCA+VehicleStack, which looks at traditional vehicles from six perspectives: mechanical, high-voltage battery and electrical, low-voltage component, software, application and cloud service.
Cai Jianyong said the system architecture should be designed so that the software is scalable and can be reused and the hardware scalable and replaceable across models, software, and even across OEMs. Ideally, the sensors should be plug-and-play.
Cai Jianyong gave an initial analysis of the architecture's value, dividing it into four dimensions: cost optimization (saving 15-20 percent in harness weight and length, reducing the number of ECUs and assembly costs), time-to-market (verifying that all models are available at once, saving development time on a large scale), enabling continuous evolution of automated driving from L0 to L4 architectures, and a unified architecture that facilitates the development of new applications across different functional domains.
On May 27, Ren Zhengfei, founder of Huawei, issued a document on organizational changes in Huawei, approving the establishment of the Intelligent Vehicle Solutions BU, which is under the management of the ICT Management Committee.
