M. Priyanka, Mahindra & Mahindra, India Sai Himaja Nadimpalli , Mahindra & Mahindra, India Keywords-Safety, Connectivity, GPS Research and/or Engineering Questions/Objective: There are many times the driver or co-passenger can experience emergency conditions whenever the vehicle is running or it is in static. These kind of situations are tough to handle even if one is victimized . The victim can be rescued on time if proper information about the situation would reach his friends or family . Limitations: In existing system, if the accidental crash happens then signal from airbag unit will wake up the mobile, Once this wake up call happens,it will activate the gsm module. The emergency contacts stored in the mobile will be dialed up and the victim can convey his emergency situation through that. The driver will be rescued only if crash happens. There is no system to rescue the driver if heart attack happens when he is driving. The additional problem which the system has is emergency contact is out of town,the victim will not be rescued Methodology: In order…

High Tech Comes to Fitness Monitoring

Wearable devices have been limited to sensing signals either on the surface of the skin or right beneath it. A new wearable ultrasound patch non-invasively monitors blood pressure in arteries as deep as four centimeters (more than one inch) below the skin, helping to detect cardiovascular problems earlier on and with greater precision. In tests, the patch performed as well as some clinical methods to measure blood pressure.

Prenatal App Reduces In-person Visits During Pregnancy

Using a mobile app reduced in-person prenatal care visits while maintaining patient and provider satisfaction. The Babyscripts app was built to deliver educational content and remotely monitor blood pressure and weight. The app gave patients information on topics like nutrition and breastfeeding, but also gave patients and providers early warnings about hypertension or abnormal weight gain, which could indicate gestational diabetes, nutritional deficiency, or edema associated with preeclampsia.

Situational Awareness, Driver’s Trust in Automated Driving Systems and Secondary Task Performance

SAE International Journal of Connected and Automated Vehicles

University of Michigan, USA-Luke Petersen, Lionel Robert, Xi Jessie Yang, Dawn Tilbury
  • Journal Article
  • 12-02-02-0009
Published 2019-05-16 by SAE International in United States
Driver assistance systems, also called automated driving systems, allow drivers to immerse themselves in non-driving-related tasks. Unfortunately, drivers may not trust the automated driving system, which prevents either handing over the driving task or fully focusing on the secondary task. We assert that enhancing situational awareness (SA) can increase a driver’s trust in automation. SA should increase a driver’s trust and lead to better secondary task performance. This study manipulated drivers’ SA by providing them with different types of information: the control condition provided no information to the driver, the low condition provided a status update, while the high condition provided a status update and a suggested course of action. Data collected included measures of trust, trusting behavior, and task performance through surveys, eye-tracking, and heart rate data. Results show that SA both promoted and moderated the impact of trust in the automated vehicle (AV), leading to better secondary task performance. This result was evident in measures of self-reported trust and trusting behavior.

Sensations Associated with Motion Sickness Response during Passenger Vehicle Operations on a Test Track

University of Michigan-Monica Lynn Haumann Jones, Sheila Ebert, Matthew Reed
Published 2019-04-02 by SAE International in United States
Motion sickness in road vehicles may become an increasingly important problem as automation transforms drivers into passengers. The University of Michigan Transportation Research Institute has developed a vehicle-based platform to study motion sickness in passenger vehicles. A test-track study was conducted with 52 participants who reported susceptibility to motion sickness. The participants completed in-vehicle testing on a 20-minute scripted, continuous drive that consisted of a series of frequent 90-degree turns, braking, and lane changes at the U-M Mcity facility. In addition to quantifying their level of motion sickness on a numerical scale, participants were asked to describe in words any motion-sickness-related sensations they experienced. Prior to in-vehicle testing, participants were shown a list of sensations that are commonly experienced during motion sickness: head sensations, body temperature change, drowsiness, dizziness, mouth sensations, nausea, or other sensations, which refer to difficulty focusing, irritability, eyestrain, or difficulty concentrating. Participants were instructed not to limit themselves to the list, but rather to report in their own words how they felt throughout the drive. For each sensation, they were also…

Analyzing the Limitations of the Rider and Electric Motorcycle at the Pikes Peak International Hill Climb Race

Brunel University-Koen Matthys
Eric Wu Engineering-Eric Wu
Published 2019-04-02 by SAE International in United States
This paper describes a post-race analysis of team KOMMIT EVT’s electric motorcycle data collected during the 2016 Pikes Peak International Hill Climb (PPIHC). The motorcycle consumed approximately 4 kWh of battery energy with an average and maximum speed of 107 km/h and 149 km/h, respectively. It was the second fastest electric motorcycle with a finishing time of 11:10.480. Data was logged of the motorcycle’s speed, acceleration, motor speed, power, currents, voltages, temperatures, throttle position, GPS position, rider’s heart rate and the ambient environment (air temperature, pressure and humidity). The data was used to understand the following factors that may have prevented a faster time: physical fitness of the rider, thermal limits of the motor and controller, available battery energy and the sprocket ratio between the motor and rear wheel. Even though the rider’s heart rate implied a vigorous exercise intensity level, throttle values indicated that the rider wanted to go faster ~33% of the time. The motor reached a steady-state temperature that was approximately 30°C below the maximum allowable temperature and thus could have handled…
