“…The measured result shows variations of 0.5-17 dB in the channels with different cable routings, despite that the cable was consistently left hanging downwards (orientation with minimum field disturbance) in the vicinity of the receiving antenna. This phenomenon highlights the role of the invehicle reverberation environment [9] in creating a fading environment where the cable (a scattering object) interacts with multiple regions of strong electric fields to result in a modified field distribution [8], [16]. Similar reverberation effects were also identified inside a bus [8] and an aircraft [9].…”

As the demand for connectivity and infotainment services increases in the automotive world, the need to measure and characterize the propagation channels inside vehicles also increases. In this work, a measurement study was performed to investigate the influence of RF cables on in-vehicle channels. It was found that, for the same transmit and receive antenna positions, the routing of the measurement cables can significantly affect the channel impulse response. This result points to the need for alternative strategies or solutions to obtain accurate and repeatable in-vehicle channel measurements.

“…Traditionally, the automotive industry uses optimisation methods in various areas during vehicle development. Business management questions (e. g. cost models [6,8,9,78]), questions concerning mechanics and electrics (e. g. car body optimization [86], hybrid powertrain [31], or EMC [80]) were often addressed and answered, to name only a few. In recent years, however, researchers and practitioners have also been concerned with the reliability of automotive E/E architectures and automatic mapping software components to available ECUs, also referred to in the literature as deployment or allocation.…”

Context Automotive software architectures describe distributed functionality by an interaction of software components. One drawback of today’s architectures is their strong integration into the onboard communication network based on predefined dependencies at design time. The idea is to reduce this rigid integration and technological dependencies. To this end, service-oriented architecture offers a suitable methodology since network communication is dynamically established at run-time. Aim We target to provide a methodology for analysing hardware resources and synthesising automotive service-oriented architectures based on platform-independent service models. Subsequently, we focus on transforming these models into a platform-specific architecture realisation process following AUTOSAR Adaptive. Approach For the platform-independent part, we apply the concepts of design space exploration and simulation to analyse and synthesise deployment configurations, i. e., mapping services to hardware resources at an early development stage. We refine these configurations to AUTOSAR Adaptive software architecture models representing the necessary input for a subsequent implementation process for the platform-specific part. Result We present deployment configurations that are optimal for the usage of a given set of computing resources currently under consideration for our next generation of E/E architecture. We also provide simulation results that demonstrate the ability of these configurations to meet the run time requirements. Both results helped us to decide whether a particular configuration can be implemented. As a possible software toolchain for this purpose, we finally provide a prototype. Conclusion The use of models and their analysis are proper means to get there, but the quality and speed of development must also be considered.

“…According to this standard, the radio disturbance produced by the electronic components in a vehicle should be measured in the anechoic chamber to shield the noise from outside [5][6][7][8]. Figure 1(a) illustrates our specific implementation according to the general description in IEC/CISPR25.…”

Abstract-In this paper, a low cost measurement system with high accuracy for radiated emission evaluation has been proposed. By combining the test data of the current probe at different positions on the harness, the measurement accuracy is improved compared with conventional single probe method. For the sake of high accuracy, a transfer function is built to map the relationship between anechoic chamber method and current probe method. Based on experiments for evaluation, the final estimation of radiated emission agrees well with the measured results in anechoic chamber. For the cases tested, the difference between the current probe method and the anechoic chamber method is less than 3 dB.
