5G Event - Future mobility

The project

5G Ride is a concept for self-driving, 5G-connected electric vehicles used in public transport. In the autumn of 2020, the vehicles were tested in traffic at Djurgården in Stockholm. In 2021 the project continues, focusing on the development of the Connected Control Tower. Urban ICT Arena manages the project in close partnership with Ericsson, Keolis, Telia, Intel and T-engineering.

 

The purpose of the project is to demonstrate safe monitoring with 5G, transfer the driver to an outside position of the vehicle and releasing resources for improved public transports. The 5G network’s unique technical features, including enhanced security, extremely high data speeds combined with low latency, means that the connected buses can respond in real time to commands from the centralized control tower. The project got a lot of positive media coverage see some of the links below.

What kind of challenges is it in a project like this?

There were several challenges in a project like this with many different technologies and providers that needed to work together to create a complete working system. In 5G Ride a demonstration system was made for public testing to show capabilities of autonomous vehicles and how they can benefit from a 5G connection. However, besides technology improvements needed, it is also customer acceptance and legal frameworks for autonomous driving on public roads that deserve great attention and remain a challenge for the future.

The automotive industry in the world is currently in a very exciting time with the 4 main focus areas: Autonomous, Connected, Electrical and shared vehicles. T-engineering is with this and other projects a small part of shaping the future of transportation.

High Feature Body Electronics

The project

Development of Body Domain electronics and functionality for High End Luxury Vehicle. SOP 2018.

Why is a company as T-engineering qualified/the best fit for a project like this?

T-engineering uses its unique capability of combining electronics and software development that results in a high end and high quality product.

What does the future hold in this area at T-engineering?

T-engineering has a full product portfolio for Body Electronics. It contains Body Computer, Door Modules, Trunk Modules, Central Gateways etc. We have the capability to tailor-made the hardware and software for the customers needs whether it is a smaller vehicle, special vehicle or luxury vehicle.

  • Advanced Vehicle State Manager controlling the function availability on the vehicle through a set of ”terminals “and vehicle modes.
  • Advanced scenario / situation based control and handling of body function (Panic Alarm, Pre- Post Crash).

Autonomous Transportation

The project

Different job sectors have a different needs when it comes to transporting goods and people. At T-engineering we take part of different concept studies to investigate what technical solutions could be used to improve performance and also be more environment-friendly. One sector is in building and road construction where for instance a lot of workers need to move to and from the building sites; which requires a lot of vehicles and temporary parking space today.

 

One solution could be automated vehicles that moves the workers between worksites as well as transporting goods. These vehicles could work more efficiently since they are shared and used by many people and with several purposes. One study and concept film was made with PEAB Trollhättan to show this kind of automated vehicle, where workers were picked up from their office and then driven automatically to the worksite. We see in the future that people onboard can sit together at a table and prepare for the upcoming site work, instead of driving.

The race car story

The project

The Race Car project was to take a standard car, in this case DongFeng Fengshen A60, turn it into a fast, high power, 4-wheel drive stylish car, ready for both movies in Hollywood and the race course. The purpose was to show the knowledge and possibilities T-engineering has both within the company itself but also in the area where we are stated. To do this with the base of a car from DFM is also a great opportunity to show the possibilities with our collaboration.

 

Never the less – it is an awesome project to do!

What kind of challenges is it in a project like this?

In a project like this there are many challenges and great moments to be as creative as you can to solve it. Like how do you fit an engine that require more space in the car’s body than the existing car has and no supplier can produce the parts in time? This time we bought a large 3D-printer and printed out the parts ourselves. It is all the twists and turns along the way that is the fun part and we can use our experience and integrate with others to make it work.

Why is a company as T-engineering qualified/the best fit for a project like this?

T-engineering has a past in Swedish automotive industry where integration challenges are a day-to-day business. With our small but competent organization and agile and problem solving mindset we are ready to take on challenges like this. We like to have a close collaboration to our suppliers to get just the right things done and don’t waste time or money for our costumer and that is why we in this advanced project decided to use as many local suppliers as possible without compromising on our vision.

Fire extinguisher

The project

The goal of the project was to redesign the Engine Management System controlling a 1.0 liter 3 cylinder direct injected 96 kW engine. All this with modern Emission Control systems from a passenger vehicle to instead power the water pump on a mobile fire extinguisher trailer. This particular application is very helpful when fighting wild fires by pumping water from nearby water sources like rivers or lakes to the location of the fire fighters.

Compared to an in-vehicle engine application the project had a number of new requirements:

  • Dashboard with very few but intuitive interfaces to the operator
  • Closed loop control of engine torque and engine speed with water pressure as feedback
  • Removal of auxiliary components like AC Compressor and power steering generator

Our engineering team at T-engineering have expert skills in Engine Management System development specifically and emission system control in general, proven from a vast number of projects within the automotive industry. By transferring this knowledge from the automotive area into the non-mobile machinery area we can enable the most environmentally friendly technology to be used not only in passenger vehicles.

 

Electric motors are great in many ways but a huge drawback is that the battery needs to be charged, which takes time. For applications where you need to power things for a long time far away from the power grid electric motors is not an option. Under these circumstances a combustion engine with state of the art emission control is the best choice.

Shared mobility

The project

Sharing Cars is a project we work on to implement and evaluate shared mobility service using electric microcars. The vehicles have been part of demonstrations and tests in Kista and in Trollhättan. The microcars are much cheaper and more environmental friendly to use than a full size car; and these small vehicles could handle the majority of the mobility needs for many people.

Why shared mobility?

Today cars are parked approx. 95% of the time. We spend a lot of money on something we use for just a small portion of the day. The vehicle also takes a lot of space, just think about all the parking lots that exists, and often we still find it hard to find a place to park. This is a problem in almost any city in the world. To share vehicles and other things are also a more environmental friendly way to manage our natural resources.

How does it work?

Today there is a clear trend when apartment houses and new areas are developed that less space is allocated for parking. Instead of every apartment having their own car space or two; other sharing mobility solutions will be available for instance bikes, electric scooters, small/medium/large cars etc. The vehicles are booked in app when to be used, and payment is included in rent or pay-per-use. Many real-estate companies see the mobility services needs to be part of the offer to attract tenants in the near future, basically something you expect to be easy available in your everyday life.

Technology now and in the future

There are several technical features that needs to be developed to make vehicle sharing service work smoothly for the end-user, and T-engineering is part of this development. The vehicles must be cloud connected to be able to be booked, found and with keyless unlock/lock functionality. We also work with wireless charging solution to simplify the usage of the vehicles even more than today, you just park the vehicle at a dedicated wireless parking spot and the vehicle charges efficiently using inductive technology, no need for the cables anymore. One feature for the near future is also the automatic driving to the charging spot, you just park where you want to, leave it, and the cars slowly drives back and parks on its pickup spot all by itself.
