Higher speeds, more sensors This brings us to the Cab’s sensor suite, which is more comprehensive than the Shuttle’s. “In the big cities you cannot imagine developing an autonomous vehicle without Lidar,” Sapet says. “Of course you need everything – onboard cameras, radars and Lidars – but in big cities the accuracy necessary for the measurement of distances is very high and cannot be achieved with cameras alone.” The Cab also places major demands on its sensor suite because of the higher speeds involved. Travelling at up to 90 kph, it will need very accurate, precise and rapidly updated range perception out to 100 m – anything less than that, Sapet says, risks problems with braking distances. Navya wants the Cab’s braking performance to be on a par with conventional modern cars, and describes the tests it has done so far as satisfactory in terms of reaction times and stopping distances. The sensor suite must also provide all- round situational awareness, particularly at junctions and crossings. At the same time, it needs a vehicle-to-everything (V2X) infrastructure comms system to confirm signs and signals seen through the camera – traffic lights in particular. Solutions developed for the Cab can also be applied to future versions of the Shuttle and other vehicles, Sapet says.
