Safety Development Trend of the Intelligent and Connected Vehicle



WCX SAE World Congress Experience
Authors Abstract
Automotive safety is always the focus of consumers, the selling point of products, the focus of technology. In order to achieve automatic driving, interconnection with the outside world, human-automatic system interaction, the security connotation of intelligent and connected vehicles (ICV) changes: information security is the basis of its security. Functional safety ensures that the system is operating properly. Behavioral safety guarantees a secure interaction between people and vehicles. Passive security should not be weakened, but should be strengthened based on new constraints.
In terms of information safety, the threshold for attacking cloud, pipe, and vehicle information should be raised to ensure that ICV system does not fail due to malicious attacks. The cloud is divided into three cloud platforms according to functions: ICVs private cloud, TSP cloud, public cloud. The transmission side classifies three APNs based on usage: enterprise-owned APN, public network APN, and public network customized APN. The vehicle end ensures information security through the vehicle firewall, border firewall, PKI password system, key management, and security chip.
In terms of functional safety, ICV function security needs to systematically consider factors such as vehicle, system and architecture. ISO 26262 design flow, AUTOSAR software architecture and perceptual information fusion are fully discussed in this section.
In terms of behavioral safety, the driving mode change of the Level 3 ICV changes the driver's responsibility. Identify driving patterns to ensure that the driver can take over and clearly communicate driver responsibility as a prerequisite for safety. In the design and evaluation, it is necessary to consider the vehicle dimension, transition dimension and driver dimension to systematically guarantee vehicle behavior safety.
In terms of passive safety, ICVs significantly reduce accidents. This can reduce some of the passive security configuration, but the reduction means integration rather than cancellation. New interior layout and constraints require the integration of passive safety and travel cabin. Active and safe sensors make passive safety intelligent. Passive safety is transformed into a combination of hardware and software
In response to changes in the connotation of automotive safety of the ICV, a new research and development concept for enterprises covering six parts was proposed. A new research development architecture for enterprises covering four parts at the same time was proposed.
