2019-01-1078
In the past, research on blockchain technology has addressed security and privacy concerns within intelligent transportation systems for critical V2I and V2V communications that form the backbone of Internet of Vehicles. Within trucking industry, a recent trend has been observed towards the use of blockchain technology for operations. Industry stakeholders are particularly looking forward to refining status quo contract management and vehicle maintenance processes through blockchains. However, the use of blockchain technology for enhancing vehicle performance in fleets, especially while considering the fact that modern-day intelligent vehicles are prone to cyber security threats, is an area that has attracted less attention. In this paper, we demonstrate a case study that makes use of blockchains to securely optimize the fuel economy of fleets that do package pickup and delivery (P&D) in urban areas.

Total Vehicle Integration and Design - Journey to Electrification, Digitization and Connectivity Leading to Autonomy

2018-04-03
2018-01-0003
Total vehicle integration and design is a complex process and deals with interactions of many subsystems. The subsystems in a vehicle not only have to perform their role but interfaces between the subsystems must be well understood to design for all the interactions. The global automotive market is following electrification, digitization and connectivity trends that eventually lead to Autonomy. Therefore, the vehicle integration design process needs to include these new use cases of these trends. The process starts with establishing the top-level vehicle metrics relative to key deliverables of the vehicle ranging from providing comfortable environment to the driver to good performance. The process of establishing vehicle level metrics is not trivial and quite often must be derived from the customer verbatim. Frequently, there are conflicting requirements and priority must be given to one over another.
