The Chinese company Baidu test robocar on the streets of Beijing had to create a three-dimensional map of the area with a positioning accuracy of a few centimeters. Security concerns forced not only to preserve the familiar controls and allow the test driver to intervene in an emergency, but also to duplicate channels of information about road conditions. In particular, a kit of ultrasonic sensors are added optical ("lidar"), as well as camera, some of which operates in the infrared spectrum to guarantee the recognition of objects in poor lighting conditions.
As reported by Reuters, advanced by the number admitted to the streets prototypes robo car American state of California is trying to formulate a common set of rules for testing such vehicles. The final version of the rules still have to go through the procedure of public hearings, but it is already known that the presence of the wheel of a certified driver is a requirement for carrying out such tests in the streets of the Californian city. By the way, Google, which boasts the largest test in California , was forced to agree to the installation of the steering wheel and pedals prototypes, although ideally the corporation would like to get rid of these authorities, as human intervention is not always safe during the transition of authority from autopilot.
The second important point - the automakers will specify the list of information to be collected is tested in California counterparts. US authorities do not want to automakers collected some "extra" information that does not affect directly or indirectly the need to ensure safety. Before admission to the road prototypes must undergo an independent examination and certification, and the information they receive during the first three years of operation must be transferred to the transport department DMV processing and systematization.
