Abstract
Interest in hybrid-electric vehicles (H-EV) and fully electric vehicles (EV) is undoubtedly growing as the motor industry and consumers look to find an environmentally friendlier and more cost effective alternative to vehicles powered solely by internal combustion engines.
Although widespread use of pure EVs as routine daily consumer transport remains a vision for the future, fully electric recreational vehicles such as off-road motorcycles are practical and can offer equivalent or better user experiences.
The KTM Freeride E electric motocross bike is one of the first such machines to be made publicly available. Quieter than a conventional 2-stroke off-road bike, it produces zero emissions, is significantly lighter, and not only offers similar peak power but enhances driveability by producing high torque even from very low motor speeds.
TT electronics was involved in the development of the KTM Freeride E from an early stage. The bike has already been ridden by impressed motorbike trade journalists and is scheduled for market launch in 2014. Since becoming involved in the project in 2008, TT electronics has taken responsibility for transforming the bike’s main electronic control unit from the prototype built by KTM in conjunction with its research partner into a robust and reliable module suitable for series production.
To create the production-ready design, the team built on its competencies in hardware design and packaging, including sensor integration, thermal management, software design, ISO 26262 safety-critical automotive systems, and ISO 16949 automotive Quality–Management System (QMS), and enhanced its in-house facilities for simulation, testing and maintenance of highvoltage power systems.
