CAN-bus is one of the most widely used vehicular buses, so the CAN-bus driver program was programmed to the vehicle terminal based on Android operating system in this paper. The programmed CAN-bus driver program included application software framework of car terminal, implementation of CAN-bus driver module, and call of Android hardware abstraction layer (HAL), etc. The research makes the vehicle terminal connect with the vehicle body network tightly, optimize the driving experience and the driving safety.

Purpose The purpose of this paper is to investigate the influence of driver demographic characteristics on the driving safety involving cell phone usages. Design/methodology/approach A total of 1,432 crashes and 19,714 baselines were collected for the Strategic Highway Research Program 2 naturalistic driving research. The authors used a case-control approach to estimate the prevalence and the population attributable risk percentage. The mixed logistic regression model is used to evaluate the correlation between different driver demographic characteristics (age, driving experience or their combination) and the crash risk regarding cell phone engagements, as well as the correlation among the likelihood of the cell phone engagement during the driving, multiple driver demographic characteristics (gender, age and driving experience) and environment conditions. Findings Senior drivers face an extremely high crash risk when distracted by cell phone during driving, but they are not involved in crashes at a large scale. On the contrary, cell phone usages account for a far larger percentage of total crashes for young drivers. Similarly, experienced drivers and experienced-middle-aged drivers seem less likely to be impacted by the cell phone while driving, and cell phone engagements are attributed to a lower percentage of total crashes for them. Furthermore, experienced, senior or male drivers are less likely to engage in cell phone-related secondary tasks while driving. Originality/value The results provide support to guide countermeasures and vehicle design.

Component-based approaches are prevalent in software development for robotic applications due to their reusability and productivity. In this article, we present an Embedded modular Software framework for a networked ro BoTic system (EmSBoT) targeting resource-constrained devices such as microcontroller-based robots. EmSBoT is primarily built upon μCOS-III with real-time support. However, its operating system abstraction layer makes it available for various operating systems. It employs a unified port-based communication mechanism to achieve message passing while hiding the heterogeneous distributed environment from applications, which also endows the framework with fault-tolerant capabilities. We describe the design and core features of the EmSBoT framework in this article. The implementation and experimental evaluation show its availability with small footprint size, effectiveness, and OS independence.

This paper designed and implemented a driver of CAN bus based ARM Cortex-M3. Combined with CAN bus technology, the paper introduces the hardware design based on STM32F205, a latest 32 bits microchip and CAN transceiver SN65HVD232. The design of CAN communication protocol and the program of software are described. The relevant key technology such as initialization, interrupt and data structure are illuminated. Experiments have verified the CAN bus driver is feasible, stabile and reliable.

Lightweight Authentication

The design of the Controller Area Network (CAN bus) did not account for security issues and, consequently, attacks often use external mobile communication interfaces to conduct eavesdropping, replay, spoofing, and denial-of-service attacks on a CAN bus, posing a risk to driving safety. Numerous studies have proposed CAN bus safety improvement techniques that emphasize modifying the original CAN bus method of transmitting frames. These changes place additional computational burdens on electronic control units cause the CAN bus to lose the delay guarantee feature. Consequently, we proposed a method that solves these compatibility and security issues. Simple and efficient frame authentication algorithms were used to prevent spoofing and replay attacks. This method is compatible with both CAN bus and CAN-FD protocols and has a lower operand when compared with other methods.

Developmental Factors

Adolescent and young adult (AYA) drivers are at high risk for automobile accidents and fatalities (1–3). Unintentional accidents were the leading cause of death in 2017 of individuals aged 15– 19 years in the United States (4). Factors that increase driving safety risk associated with AYA drivers include lack of driving experience, developmental factors such as poor executive function, and propensity for risk-taking behaviors (5,6). Furthermore, cognitive abilities such as self-control and emotional regulation are continuing to develop through late adolescence and into young adulthood, making AYA drivers particularly vulnerable to practicing unsafe driving behaviors (7). Brain development—in particular the prefrontal cortex, which relates to impulse control—is known to continue well into young adulthood, not reaching adult dimensions until the mid-20s (8,9).
