Volvo’s DriveMe project towards autonomous driving

The name of the project is “DriveMe – Self-driving cars for sustainable future”.

Autonomous vehicles are an integrated part of Volvo Cars’ vision of zero traffic fatalities.

The project will start in 2014 with customer research and technology development, as well as the development of a user interface (UI) and cloud functionality. The first self-driving vehicles are expected to be on the roads in the home town of Volvo Car Group by 2017.

The project will involve 100 self-driving cars using approximately 50 kilometres of selected roads. These roads are typical commuter arteries and include motorway conditions and frequent queues.

The project also includes fully automated parking, without a driver in the car. This allows the driver to walk away from the car at the parking entrance while the vehicle finds a vacant spot and parks by itself.

A prototype vehicle has already been developed. At the touch of a button the vehicle takes over the braking, the accelerating and the steering. The vehicle though needs to be supervised by the driver on the grounds that the system is in development.

On-Line Electric Vehicle (OLEV)

The On-Line Electric Vehicle (OLEV) is an electric vehicle that can be charged wirelessly while standing still (static charging) or in-motion (dynamic charging). OLEV receives power from the road wirelessly thanks to a new technology known as Shaped Magnetic Field In Resonance (SMFIR). Power Lines are buried 15 cm under the road surface. These electrical cables generate a magnetic field. There is a power Pick-up Module (coils sets) under the OLEV. The power transfer is only effective between two resonant coils – Road-Embedded primary Power Track coil and vehicle attached secondary Pick-up coil. OLEV’s battery is smaller comparing to the battery pack of the conventional EV. The distance gap between the road surface and the vehicle is 20 cm.
