TK Engineering Oy is designing a telematics-based diagnostic system that will be used in the City of Tampere’s new Smart Trams. The development work is being carried out in close co-operation with Transtech Oy, which belongs to the Škoda Group.
The purpose of the diagnostic system is to collect information about the trams distributed control systems using, for example, CAN technology and other data networks. In developing the system, its scalability in the future, both in the short and long term, is being taken into account as much as possible. The collected data will be used to improve the reliability of the trams and to create services to improve passenger comfort.

Elways AB (Sweden) who develops a system that allows electric road vehicles to charge while driving, rather than having to stop and charge at a stationary location. They need some CAN based control system design and implementation support from TKE.
TKE provided the control system for detecting the rail and the power collector arm consists of a mobile PLC (both software and hardware) and sensors which are controlled via CAN bus. CANopen network and J1939 network are used in combination in the system.
Scania has used an Android driver developed by TK Engineering (TKE) and CAN interfaces from Kvaser to develop a user-friendly tablet solution for HGV driver training.
Until the launch of the HGV driver training tablet, Scania’s driver trainers had to perch between the front seats in order to see the instrument panel and determine exactly how the driver was operating the pedals. Whilst being ergonomically awkward, the practice presented a safety risk. “We realised that in worst case our trainers could be injured in a harsh braking situation,” says Magnus Andersson, Product manager at Scania’s E-Business and New Media.
TKE OY, specialized in CAN-technology, has supplied a control system for the Big Float 800 dredging excavator of REMU Ltd, which is leading supplier of innovative screening and excavation systems in Europe. This special excavator consists of a basic excavator, where the normal track system is replaced with floating pontoon/track-system. This helps the excavator to float on lakes or sludgy marshes and gives the Big Float excavators unique abilities to reach hard to get places.
TKE OY, specialized in CAN-technology, has supplied a Servicetool to Hybricon Bus Systems, Sweden who develops and manufactures the world’s most energy-efficient, clean and quiet system for public transport buses with an aim of delivering complete systems for electric public transportation in cities.
Hybricons electric buses are controlled with several ECUs steering the electrical motors, batterypacks and charging. These ECUs are using CAN as communication protocol. The Servicetool in PC was supposed to communicate via CAN to these ECUs so TKE used Kvasers CAN to USB-interface to connect the service computer to the bus communication system.
TKE supplied electronics for the 2010 Olympic winter games held in Vancouver, Canada. The lighting sequences of the Olympic rings that greet travelers to Vancouver international airport during the year that leads up to the Olympic Games are controlled through 5 TKE WCS-10 CAN-switches. The rings were lit by British Columbia Premier Gordon Campbell during festivities March 5, 2009.
During year 2016 TKE was contacted by a customer to renew their current Water Jet control system. The customer had reach a limit in their control system that made it time consuming to produce in large quantity. It was discussed with the customer that the new control system needs to be able to replace the old system with all it´s functionality but possible to manufacture in higher quantity with less man hours.
TKE started the process by gathering requirements and making a suggestion for the next generation control system. The core of the control system was designed to be hardware independent and can be reusable. Both CANopen and J1939 protocols were used for different communication purposes.
