The greatest number of patents in the field of pilotless technologies and autonomous driving among all other carmakers belongs to Toyota. Japanese have begun researchers in this area in 2005, and in 2006, the first results were already patented. Japanese, however, don’t try to escalate events. Toyota presented the automatic car with self-training function recently. The car is capable of remembering routes, pay for the place on the parking or to choose more convenient option of it.
A special emphasis of the program is put on opportunities of self-training and improvement of the car, its ability to be guided in road infrastructure and to contact with other participants of the movement. Using the system of light detection and definition of range, the radar and touch cameras allowed reducing the dependence of the system on high-precision navigation maps.
The basis of the system is made by two executive algorithms developed by Toyota known under the names Chauffeur (Driver) and Guardian (Keeper). Chauffeur is the mode of completely pilotless driving. It corresponds to the 5th and 4th levels of classification of SAE, the standardizing body of Community of automobile engineers.
Guardian is a help algorithm at driving, which constantly monitors a road situation and actions of the driver. At the emergence of potential threats, Keeper warns and takes measures to avoid road accident if it is necessary and possible.
‘It is the clever car, which becomes even cleverer eventually, – the managing director of TRI says. – It studies individual driver’s habits and preferences of the person driving and fills up knowledge base thanks to data exchange with other cars and infrastructure facilities. We expect that the algorithm can already be widely adopted in the near future on production models, helping drivers with difficult situations, reducing the risk of accident and saving lives.’
At the same time the Automatic Emergency Braking system, which is independently slowing down the car at risk of the crash will become the serial equipment of almost all Toyota and Lexus models presented at the market of North America already by the end of 2017. It will occur five years earlier than it is demanded by NHTSA (National Highway Traffic Safety Association), the principal regulating organ on road safety in the USA.
