Automatic driving of trains can significantly reduce the energy cost and enhance the operating efficiency and safety. The automatic train driving system has to be an embedded system that can run onboard with low power, which necessitates an efficient inference model. In this article, a level-wise driving knowledge induction approach is proposed for embedded automatic train driving systems. The coincident driving patterns in the records of drivers with different experience levels suggest the suitability of a driving experience knowledge rule induction approach. We design a two-level learning approach to obtain both the driving experience pattern in fuzzy rule-based knowledge form and the detailed parameters of velocity and gear by regression learning methods. With 8.93% energy consumption reduction compared with average human drivers, the experiments indicate the effectiveness of our approach.

Driving Scenario

This article describes a drink-driving scenario where a woman was apprehended for driving under the influence (DUI) with a blood alcohol concentration (BAC) of 256mg/dl1 The correctness of this result was vigorously challenged by a medical expert witness for the defence, who was actually a specialist in alcohol diseases. Despite reanalysis to confirm the BAC as well as a DNA profile to prove the identity of the blood specimen, the woman was acquitted of the charge of drunk driving by the lower court. However, she was subsequently found guilty in the High Court of Appeals with a unanimous decision and sentenced to four weeks imprisonment. This case report illustrates some of the problems surrounding the use of expert medical evidence by the defence to challenge the validity of the prosecution evidence based solely on a suspect's BAC. In situations such as these, an expert witness should be called by the prosecution to clarify and, if necessary, rebut medical and/or scientific opinions that might mislead the court and influence the outcome of the trial.

To enhance the stability and accuracy of the digital-physical hybrid simulation system of a modular multilevel converter-based high voltage direct current (MMC-HVDC) system, this paper presents an improved power interface modeling algorithm based on ideal transformer method (ITM). By analyzing the stability condition of a hybrid simulation system based on the ITM model, the current of a so-called virtual resistance is added to the control signal of the controlled current source in the digital subsystem, and the stability of the hybrid simulation system with the improved power interface model is analyzed. The value of the virtual resistance is optimized by comprehensively considering system stability and simulation precision. A two-terminal bipolar MMC-HVDC simulation system based on the proposed power interface model is established. The comparisons of the simulation results verify that the proposed method can effectively improve the stability of the hybrid simulation system, and at the same time has the advantages of high simulation accuracy and easy implementation.

Distance measurement methodologies based on the digital camera usually require time-consuming calibration procedures, some are even derived from complicated image processing algorithms resulting in low picture frame rates. In a dynamic camera system, due to the unpredictability of intrinsic and extrinsic parameters, odometric results are highly dependent on the quality of extra sensors. In this paper, a simple and efficient algorithm is proposed for relative distance estimation in robotic active vision by using a monocular digital camera. Accuracy of the estimation is achieved by judging the 2D perspective projection image ratio of the robot labels obtained on a TFT-LCD (Thin Film Transistor – Liquid Crystal Display) monitor without the need of any additional sensory cost and complicated calibration effort. Further, the proposed algorithm does not contain any trigonometric functions so that it can be easily implemented on an embedded system using the Field Programmable Gate Array (FPGA) technology. Experimental results are included to demonstrate the effectiveness of the technique.

Objectives: The present review of literature examines the relationship of alcohol consumption and fitness to drive. The legal limit (1,6 ‰) for establishing fitness to drive by means of a medical-psychological assessment (MPA) in Germany is analyzed on the background of published empirical research to present recommendations for the improvement of the current legal situation and administrative practice. Methods: 103 published articles have been analysed (inclusion criteria: completeness, comprehensibility, and experimental manipulation of the blood alcohol concentration [BAC]). The number of alcohol-induced impairments is to be shown in a quantitative analysis. The qualitative analyses of the studies will reveal the impaired areas of psychological and medical functioning. Results: It appears that 97 % of the documented impairments occur at a maximum BAC of 1,1 ‰. Numerous skills are impaired by low doses of alcohol (e. g. attention, memory, perception). Conclusion: Alcohol-induced impairments arise at a BAC far below 1.6 ‰, which marks the legal limit for a medical-psychological assessment (MPA) after drunk driving in Germany. The BAC limit in the current ordinance for assigning a medical-psychological fitness assessment cannot be confirmed on the basis of research findings. A reduction of this BAC limit to 1,1 ‰ is proposed.

An experiment was conducted to investigate the feasibility of developing an in-vehicle skill-based drunk driver detection and deterrence system. The experiment compared two well-developed psychomotor test devices, the Tracometer and the Critical Tracking Task (CTT), for their ability to detect alcohol intoxication. The Tracometer employed a pursuit tracking task whereas the CTT employed a compensatory tracking task. Twenty male subjects, aged 19 − 30 were trained on the Tracometer and the CTT over a three day period. On two subsequent test days, they were treated with either placebo or alcoholic beverages designed to bring their peak Blood Alcohol Concentration (BAC) to 1.2% (1200 mg/L). On each day, the subjects were tested once before treatment and six times after treatment at hourly intervals as their BAC levels declined. The results indicate that the Tracometer was more sensitive than the CTT to the the effects of alcohol over a wide range of BAC levels. At a BAC level of .08%, performance on the Tracometer deteriorated by 16% whereas performance on the CTT deteriorated by only 7%. Using optimized pass/fail protocols, the Tracometer failed 60% of subjects with BAC in the range .08–1.0%, whereas the CTT failed 34%. At BAC levels above 1.0%, the Tracometer failed about 85% whereas the CTT failed 40%. These results clearly illustrate the potential of the Tracometer as a test of alcohol intoxication. Although the impetus behind the study was the development of drunk-driving countermeasures, the technology can be easily extended to include other applications.
