This paper presents the advantages of modelling an application destined for automotive using automotive standard architecture (AUTOSAR). This standard is structured in layers and is trying to make the software application independent from the microcontroller unit (MCU) specifications. By structuring an application in this way, it reduces the time and the cost of developing new ones for a different microcontroller or for creating new applications with a similar purpose for the same microcontroller. Also, the diagnosis for the errors is improved a lot, because it provides mechanisms to detect them, and, having a very structured form, it is easy to find them in comparison with the older procedures used for the soft-ware development that are different from one producer to another. This standard architecture helps to get better results in software development and embedded systems for the automotive area. Here is presented a primitive implementation for an electric automatic gearbox that can be developed more when new features are required.
TopIntroduction
The functionality of vehicle guidance systems is now the focus of research and development for autonomous vehicles. Several experimental vehicle demonstrations have demonstrated the outstanding capabilities described above, with the most recent ones listed first. (Reschka, 2016)
As an illustration, the drive on the Bertha-Benz route completed by the Karlsruhe Institute for Technology and Daimler AG (Urmson, 2012 & Reschka, 2016), the Stadtpilot project of the Technische Universität Braunschweig (Nothdurft 2011 & Wille 2010), the operations of Google Inc. (Chatham, 2013; Reschka, 2016; Urmson, 2012), the BRAiVE Research Institute and the VIAC Project of the VisLab Institute of the University of Parma (Bertozzi, 2013 & Broggi, 2013), the research activities of the Collaborative Research Centre 28 of the German Research Foundation (DFG) (Stanek, 2010; Stiller, 2007; Kammel, 2008 & Thuy 2008) and the results of the DARPA Urban Challenge (Singh, 2008).
A safety driver was always present in the experimental vehicles on public roads and in traffic to keep an eye on the technical system. This person was required to step in if a technical issue developed, rendering the current scenario outside the scope of the vehicle or if a different circumstance called for it.
According to [20], the recommended test drives on public highways are categorised as semi-automated due to the technical system's requirement for constant monitoring. Future vehicle guiding strategies with increased levels of automation will strive to operate autonomously in every circumstance without human supervision.
Therefore, a safety concept covering the many stages of the development process, such as the specification, design, development, and functional tests, is needed when developing vehicle guiding systems. Additionally, the system must have safety components that can reach or try to maintain a so-called safe condition.
Automated vehicles (AVs) are automobiles in which at least one aspect of driving control, such as steering or speed control, operates independently of the driver. Avs use a variety of sensors to acquire data.
Assisted driving is a field that is growing very fast nowadays. Most majority of car constructors are trying to improve the safety of the drivers and to make driving to be more accessible.
The car’s gearbox is one of the first parts of a vehicle which was shifted from manual to automatic. This happened for the safety of the drivers and users but also in terms of quality because of how components.
