| 摘要： | The sheer amount of data being produced by vehicles and trailers is staggering: for example, telematics provider Michelin Connected Fleet covers more than 700,000 assets (of all types), and these are monitored in around 2.5 billion positions a month. Incidentally, this is the brand, just launched in the UK, which comprises the former companies Masternaut in Europe, NexTraq in North America, and Sascar in South America. "But that's just positions," says chief technology officer Laurent Castellani. "We are also capturing 300 million frames a day. We take the information from the vehicle, we aggregate that into a small packet of data - the frame - and we send that, secure and encrypted, to the platform. "We push data between every 30 seconds and every two minutes, to make sure we don't increase our telecoms costs. But the sampling of the data is happening with higher frequency: normally between one and five times a second, but we could go up to 400 times a second if needed." Another tyre-related telematics company is Bridgestone Mobility Solutions, which owns Webfleet. At its recent mobility conference, Bridgestone's vice president of data solutions & innovation, Raghunath Banerjee, said: "Connected vehicle data is vastly underutilised," but the firm is trying to change that. |
