The mobility sector has a large number of attainable to deliver connectivity into the automobile, making it a fascinating area for builders of IoT programs. The researchers on the Bosch IoT Lab are running on quite a lot of subjects with the purpose of bringing the mobility area and the IoT nearer in combination. Timo Gessmann, Director of the Bosch IoT Lab, supplies an outline of the analysis he and his colleagues are accomplishing.
STEFANIE KOWALLICK: On the Bosch IoT Lab, you’re running on a number of analysis subjects in reference to mobility. Your purpose is to leverage the auto as a sensor. Are you able to provide an explanation for what that suggests?
Timo Gessmann is the director of the Bosch IoT Lab. Along side his workforce he’s running on IoT-enabled new trade fields with a focal point on mobility, power and well being in addition to IoT trade fashions, synthetic intelligence and blockchain era.
TIMO GESSMANN: The IoT is all about connecting issues. These days there are lots of sensors in a automotive that may measure temperature, automobile pace, how a lot force you set at the brakes, and a lot more. With the assistance of the IoT it is possible to measure and analyze relevant car data. Automobile sensor knowledge is the important thing to offering motive force help, bettering protection, and making riding extra sustainable. We observe the main of “privateness by way of design” in our IoT tasks. In different phrases, knowledge is encrypted and transmitted anonymously.
What attached mobility analysis subjects are you now running on?
We’re specializing in 3 analysis subjects. The primary is eco-driving. We need to be informed extra about peoples’ riding conduct and work out how drivers can also be motivated to modify their conduct and pressure extra eco-responsibly. The purpose is to cut back gas or power intake by way of examining knowledge this is to be had in a automotive. We will be able to then strengthen drivers by way of offering customized eco-feedback. The second one matter is protection on public roads or extra exactly coincidence hot-spot warnings and prediction. We’re researching techniques to forestall site visitors injuries. We goal to strengthen drivers with new services and products and new purposes to give a boost to street protection. The 3rd is customized mobility and motive force well being & well-being. The point of interest here’s on bettering motive force and passenger convenience by way of enabling the auto to evolve to their wishes. In each and every of those fields, we’re cooperating with universities to be able to deliver the most recent medical analysis wisdom at the side of the sensible subjects Bosch is recently running on.
What’s eco-driving all about?
We’re running at the side of psychologists from ETH Zurich and the College of St. Gallen. Our analysis can also be summed up within the query: “How are we able to give a boost to a automotive and its infotainment gadget to inspire drivers to act extra eco-responsibly?” So, from a systematic point of view it’s all about behavioral alternate. This in flip is dependent upon non-public motivation. We’re taking a look on the components that affect automobile power intake and what can also be achieved to steer particular person drivers to undertake a extra eco-friendly technique to riding.
How do you inspire drivers to pressure extra eco-responsibly?
You’ll be able to’t alternate a motive force’s conduct just by appearing them their present power intake. Lately, vehicles provide you with a sign of ways a lot power you utilize in line with 100 kilometers. That is normally displayed as simple textual content at the dashboard, which isn’t motivating. We subsequently evolved a smartphone app that presentations a so-called “eco-tree.” When you pressure eco-responsibly, the tree grows and produces purple apples. When you don’t pressure eco-responsibly, the tree stops rising and the apples fall from the tree. On this approach, we need to give drivers extra visible suggestions. The theory at the back of our app is analogous to a health tracker that screens your job, offers you direct suggestions and optimistically motivates you to take extra workout.
We evolved a number of apps with the assistance of psychology mavens. Then we examined those apps within the box with real-life drivers, who in overall drove just about 1 million kilometers in Switzerland. We came upon that the eco-tree is a lot more motivating for a motive force than simple textual content, as an example.
How is the eco-driving app attached to the auto?
In our box research in Switzerland we used a so-called OBD dongle. This software is hooked up to the auto and collects knowledge at the automobile’s pace and gas intake, amongst different issues. This information is then transmitted to our smartphone app which supplies suggestions to the driving force.
Bosch IoT Lab
The Bosch Web of Issues Lab has been officially opened in September 2012. This is a cooperation between the College of St. Gallen, ETH Zurich and the Bosch Team. The Bosch IoT Lab is exploring new IoT-enabled product and trade fields with a focal point on mobility, sustainable residing and dealing, blockchain era, and IoT trade fashions.
Let’s discuss accident-free mobility. Are you able to give a basic review of this matter?
We requested ourselves: “How can the IoT lend a hand cut back injuries on public roads?” When an coincidence occurs, the police most often write up a file. In Switzerland this file knowledge is to be had in virtual shape in a database held by way of the Swiss public street government. We got get right of entry to to this information, which covers round 270,000 coincidence studies over a length of six years. With the assistance of synthetic intelligence, we analyzed them and came upon that there are places in Switzerland the place the frequency of injuries is upper than moderate. We name those places “coincidence hotspots”. We then fed the coincidence hotspot knowledge into our smartphone app, referred to as Avertu. In line with this information, the app warns drivers if they’re within the neighborhood of such an coincidence hotspot.
Are there use cases apart from driver warnings where the accident-free mobility concept can be applicable?
Yes, the data can also be used to improve the public infrastructure. In St. Gallen, for example, we detected a high number of accidents at a particular intersection. We asked the local traffic department to take a closer look at this intersection. They found out that the traffic lights were switching too fast. The city then changed the timing of the traffic lights and therefore improved the infrastructure to make traffic safer. This shows that there is potential to collaborate with different interest groups.
The third research topic you are working on is personalized mobility and driver health & wellbeing. Can you tell us something more about this topic?
It doesn’t take much intelligence to realize that car data can provide insights into the technical aspects of driving. Think about mobile diagnostics: Your car can, for instance, tell you when the next oil change is due. However, in our view, the technical aspects are just one part of a wider issue. It’s also important to take the driver and the passengers into consideration. They are an essential part of the system and we want to optimize the collaboration, so to say, between a driver or a passenger and the car.
One of our current research projects aims to find out how cars can be better designed to accommodate the needs of the driver and passengers. We want to develop a service that takes the user’s individual requirements into account. This could be in the form of setting the right temperature or providing you with the infotainment offering you desire. That’s what we call personalized mobility.
What specific aspects are you are dealing with as part of this topic?
Currently, we are conducting research on the stress level of drivers. The goal is for the car to detect your stress level and respond in a way that will reduce it. Building on this, the logical next step for us is to take the general health status of the driver into consideration and support the driver in critical situations.
How do you approach detecting the stress level of drivers?
We are collaborating with universities and medical professionals. In our field tests we used wearables that can be attached to the wrist or arm. We also measured drivers’ blood pressure and vehicle parameters such as speed, acceleration and deceleration. Then, we tried to find correlations in the data we gathered, to find out which driving situation is stressful for a specific person.
Are there specific topics you are working on regarding drivers’ health?
A relatively new topic is diabetes, where we are collaborating with a Swiss hospital. We want to find out if a car can provide insights into the blood sugar level of the driver. The driver could then be informed to take a break to take their insulin medication. It’s ongoing research we started a few months ago. All our research projects are based on the “privacy by design” approach and conducted in close collaboration with the ethics commission.
Do you already have ideas how car data can provide insights into the blood sugar level of the driver?
The participants in our tests measured their blood sugar level in the same way as usual. We then compared the measured blood sugar level to the car data. We used the sensor data to look for correlations. We noticed that low blood sugar levels appear to have an impact on vehicle speed and steering angle. And there may be other correlations between the driver’s blood sugar level and the car data, but it’s too soon to tell because this research is still at a very early stage.
What next steps do you have planned concerning personalized mobility solutions and driver health monitoring?
We want to conduct more field tests, since there are still many unanswered questions. We also want to collaborate with OEMs and other external partners. We cannot influence the design of a vehicle interior by ourselves. By collaborating with an OEM, we would be able to make changes to the interior of a car to make it more comfortable and safer for drivers and passengers.
