Mercedes F1 to use Qualcomm 5 GHz WiFi for its tire data

In Formula 1 you need more of everything. More speed, more grip, more hospitality, more money. And you need data, reams and reams of data. The Mercedes-AMG Formula 1 team – the guys with the silver cars driven by 2015 F1 champion Lewis Hamilton and his teammate Nico Rosberg – need so much information that they've teamed with Qualcomm to wirelessly upload thermal imaging data of its tires. During a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Live telemetry has been a feature of Formula 1 for 20 years, though there are more restrictions on it than in the past. (In the days leading up to last weekend's United States Grand Prix in Texas, Formula 1 major domo Bernie Ecclestone said that F1 needs to cease being an engineering war and return more responsibility to the drivers.) Nevertheless, F1 teams gather vast amounts of data during a race weekend, particularly in practice sessions during which restrictions on what they can upload from cars – from engine/power unit parameters to aerodynamic loads – are less prohibitive. For example, during a typical race weekend Mercedes's two racecars will generate approximately half a terabyte of data. Mercedes F1 technical director Paddy Lowe points out that the standard telemetry system simply doesn't have the bandwidth to handle the thermal tire imaging data that the onboard thermal cameras generate. Why do you want a thermal video of the tires? Because it tells the engineers and drivers precisely how much temperature there is across the surface of a tire during a lap, in corners and on the straights. It also indicates how quickly the tires come up to temperature and when they potentially overheat. Understanding the temperature variations allows the team to set the cars up optimally for grip and tire life during a stint. Qualcomm's system works with the race cars like this: Each car has forward- and rear-facing cameras in a winglet mounted on the left side of the engine intake behind the driver's head, which continuously record thermal images of the tires. As a Mercedes enters the pit lane, it passes a Qualcomm 802.11ac WiFi receiver to which it uploads the thermal data. As the car nears the garage, another receiver takes over the upload. Several Qualcomm Snapdragon 805 processors crunch the raw data as it uploads. The data is encrypted – there are always prying eyes in Formula 1.

Germany is finally getting serious about self-driving cars

Germany cleared the way for its giant automotive industry to develop and test self-driving cars, when the upper house of its parliament approved on Friday a law setting out the conditions under which they could take to German roads. Under the law, first mooted by Chancellor Angela Merkel last year, a driver must be sitting behind the wheel at all times ready to take back control if prompted to do so by the autonomous vehicle. Germany is home to some of the world's largest car companies, including Volkswagen, Daimler and BMW, all of which are investing heavily in a technology seen by transport minister Alexander Dobrindt as the "greatest mobility revolution since the invention of the car." That's not to say that German automakers have been standing still in the face of autonomous technology. VW recently outlined its vision for autonomous vehicles. BMW has already demonstrated self-driving vehicles in the United States, and Mercedes-Benz has partnered up with German auto supplier Bosch on autonomous technology. The new legislation allows German car companies to road-test vehicles in which drivers will be allowed to take their hands off the wheel and their eyes off the road to browse the web or check e-mails while the vehicle handles steering or braking autonomously. The legislation requires that a black box record the journey underway, logging whether the human driver or the car's self-piloting system was in charge at all moments of the ride. This will be crucial for apportioning blame in accidents. The driver will bear responsibility for accidents that take place under his or her watch, under the legislation, but if the self-driving system is in charge and a system failure is to blame, the manufacturer will be responsible. The law will be revised in two years' time in the light of technological developments, with data protection and the use of the data collected during rides a key point that has yet to be fully addressed. Companies around the globe are working on prototypes for self-driving vehicles, but such cars are not expected to be available for the mass market before 2020.

Race recap: 2016 Australian F1 Grand Prix a rowdy start to season

The three brief Formula 1 tests ahead of the current season belied how much had gone on since the last race in November: Infiniti subbed out for Tag Heuer, Renault is back, the all new Haas F1 team, a revamped Manor, three brand new drivers and two returning drivers, a raft of regulation changes among the newly tilled soil. The four engine manufacturers spent a combined 67 tokens among the 138 in the kitty, Renault using just seven of their 32. The only conclusive proof to come from the annual intermission was the otherworldly capability of Mercedes-AMG Petronas. The Silver Arrows didn't even try the super- and ultra-soft tires, focusing on reliability instead of speed. The result? They ran more than 19 race distances, obliterating the lap totals of every other team. There are certainly a few people who enjoyed the complicated new rolling-elimination qualifying format fast-tracked to approval just a few weeks ago. They were wildly outnumbered by those who thought it was awful, including the same team heads who voted for it. We'd probably have to go back to the debacle at the 2005 Indianapolis Grand Prix for an equivalent fiasco when Michelin pulled its teams over safety fears, leaving six cars out of 20 to qualify. In Australia, within 24 hours of the conclusion of qualifying, the new format had itself been eliminated. Nevertheless, qualifying also taught us what didn't happen over the winter: any other team progressing enough to outduel Mercedes. After admitting that he dropped off after winning the championship last year, then getting questioned in the press for some dubious off-season activities, Lewis Hamilton proved he can still turn it on when he wants to. The Brit smoked the Albert Park track in 1:23.837, more than three-tenths of a second ahead of teammate Nico Rosberg in second place. Ferrari did make strides during the off-season, but only enough to keep the same gap it had to Mercedes last year: Sebastian Vettel lined up third, a half-second behind Rosberg, teammate Kimi Raikkonen another four-tenths back in fourth place. Max Verstappen said Toro Rosso is the best of the rest, the Dutchman taking fifth place in front of Felipe Massa for Williams in sixth and Toro Rosso teammate Carlos Sainz in sixth. Daniel Ricciardo – who wasn't smiling after qualifying – kept Red Bull and its new "Tag Heuer" engines in the conversation with eighth on the grid.
