Covid-19 caused a backlog of driving test appointments. The driving test waiting time estimator tool will tell when you are invited to book a car driving test.
On the Android end, AlcoDroid is another feature-packed drinks logger, with personalized user profiles, drink logging and a BAC estimator. You can also set long term drinking goals and view your consumption habit and expenses over time. It's main weakness is that it doesn't have the same ...
The FC rate under the China Light-Duty Vehicle Test Cycle (CLTC) shows a 13.5% higher value than WLTC test results [24]. The acceleration and deceleration modes of WLTC show relatively more aggressive driver behaviour due to their large time proportions [25]. Ma et al. (2019), indicate ...
The following subsection presents the authors’ proposition toward a speed estimator using their BL-detector device that provides better accuracy for the speed of the moving vehicles than using the Friis formula. 3.2. End-Node Speed Estimation and Validation Process The authors propose a new ...
The time length of the collected signals was 20 s for each test. 2.3.3. Post-Processing of Data The estimator H1H1 [43] was used to estimate the AM curves. The frequency resolution of the resulting AM curves was 0.5 Hz because sub-records of 2 s were extracted from the whole time-...
The PSD estimator method used in the driving fatigue detection experiment was Welch’s method. The estimation of PSD was analyzed into five frequency bands: ultralow frequency (ULF)—under 0.003 Hz, very low frequency (VLF)—between 0.003 Hz and 0.04 Hz, low frequency (LF)—between 0.04 Hz...
which facilitates the accurate estimation of the road surface adhesion coefficient and at the same time feeds back the information to the driving state estimator for continuous correction, so as to consider the dynamic characteristics of the road surface, thus enhancing adaptability and stability and ...
