Recently, representatives of Google corporation , which has been developing automated driving systems, reported about the desire to reduce dependence of robocar on wireless interfaces, which can transmit the necessary information for decision-making.
However, as explained Reuters resources available autopilot system for cars are heavily dependent not only on accurate digital maps, but also on the availability of road markings, traffic signs and the correct placement of traffic lights. For example, Volvo specialists were unpleasantly surprised by the condition of road markings on some American roads, which is why the Swedish prototype car with automatic pilot was not able to move independently . Incidentally, in the US, about 65% of the roads are in poor condition, so robocar will have to rely on multiple channels to obtain the necessary navigation information along the roads. Interestingly, the German engineers have learned sedan Mercedes-Benz E-Class held in his band in the absence of road markings - Automation focuses on road barriers and trajectory neighbors downstream. 23 sensor system is able to keep the car in its lane at speeds up to 135 km / h.
Excessive number of sensors, allowing with some confidence to guarantee adequate "orientation of the vehicle on the ground," significantly increases the value of the vehicle - according to some estimates, $ 4,000 only in terms of cost. Car manufacturers will have to spend in the next decade at least $ 1 billion. For the development of the autopilot functions, and these costs will be gradually passed on to customers budget. Even accurate digital maps will force automakers to pay $ 50-60 for each machine, with the most conservative estimates, not covering the actual cost of map compilers.
Fortunately, the sensors become cheaper and more compact. If the first generation of optical sensors ( "LIDAR"), which uses Google's company on their prototypes, worth under $ 75,000 for the system, now under development device for $ 250, and by 2018 the cost will drop to $ 100. In the US, by the way, navigation robocar complicated by the fact that different states can use their tradition road marking and traffic lights. Related Products :
