For intelligent traffic, Toyota blends infrastructure and vehicle electronics

November 12, 2013 // By Christoph Hammerschmidt
"Harmonic Mobility" (Ha:mo) is the name of Toyota's future-oriented traffic concept currently tested in Japan. At a special exhibition within the upcoming Tokyo Motor Show, the carmaker will introduce several elements of its concept. According to Toyota's believe, these elements will significantly change the face of individual mobility.

At Toyota's booth at the show, alternative vehicles such as the i-Road three-wheeler will meet an intelligent infrastructure and sophisticated assistant systems which will equally reduce the risk of an accident and environmental burden.

In detail, Toyota will present three futuristic vehicles. The i-Road is an ultra-compact electric vehicle with wheel hub drive and a driving range of 40 to 60 kilometres. It combines the properties of a bicycle with the comfort and stability of a car and thus will offer a completely new driving experience, Toyota promises. In addition, Toyota will showcase fro the first time a two-seater version of its COMS electromobile. The T-COMS, as the two-seater has been christened has been developed by Toyota Auto Body Co. and will integrated into the company's Ha:mo project by mid-December. The third vehicle at the Toyota booth will be the Winglet, an ultra-compact two-wheeler that resembles the popular Segway. To control the Winglet, a sensor electronic control unit developed on the basis of robot technology is at the driver's disposition.

In addition, Toyota plans to demonstrate a number of driver assistance systems and technologies for automated driving which enable the vehicles to automatically communicate with the infrastructure, pedestrians and other vehicles. A car-to-infrastructure driving simulator will illustrate how ambient-consciousness assistant systems can minimise the risk of an accident by utilizing car-to-infrastructure, car-to-car or pedestrian-to-infrastructure communications. In this context, the carmaker attaches great importance to smart driver assistance systems, in particular the company's new Automated Highway Driving Assist (AHDA). This system combines the functionalities of a cooperative-adaptive cruise control system (C-ACC) with a lane-keeping assistant (LZC). While the C-ACC communicates with vehicles in front as well as with following ones to keep safe distance to them, the LTC utilizes sensors-based date to keep the vehicle in the centre of the lane.

The third major element in Toyota's future traffic vision is a smart infrastructure. This infrastructure will embrace elements that collect
