The third generation of automatic driving test prototype car has just been released for more than a year, and Ford has completed the iteration again. The new fourth generation test car is definitely the most changed generation since the project started in 2013. With Ford and Argo.ai The commercial operation time of automatic driving in 2022 is approaching, and the modified sensor suite and computing platform have been installed on the escape hybrid platform. < / P > < p > before escape, Ford had been using fusion hybrid (the domestic Mondeo) as the automatic driving platform. In the past few years, this model has been the standard configuration of other developers. Not only is its product strength mature, many technicians and engineers also know how to use electronic structure to obtain power, control steering, thrust and brake < / P > < p > however, fusion has stopped production in North America, and many developers have decided to follow waymo and buy Chrysler Pacifica The plug-in hybrid car acts as the test platform of automatic driving. Don’t forget, as MPV, it is more suitable for robotaxi and distribution services. The intimate FCA has even specially built a “finely decorated” Pacifica, with redundant systems, interfaces and locations of various hardware reserved. Unfortunately, Ford can’t choose. However, the latest Escape is not bad, after all, its flexible integrated body structure will also be used in Ford’s special autopilot car in the future. But the autopilot is more like a van than a Escape like SUV. Of course, this is not important, because the focus of the moment is not the test car, but all kinds of hardware. < / P > < p > “we’re looking forward to escape. Of course, mass production vehicles need a lot of modifications to integrate automatic driving technology, and more efforts are needed to ensure the industry’s first-class experience. ” Said John Davis, chief engineer of Ford’s automatic driving division. “Escape will strengthen our foundation and help Ford gain some advantages.”

in view of the growing proximity of Ford’s self driving system from the mass production version, they also upgraded the sensor suit on Escape. First, the roof structure was greatly improved, and Ford introduced a new Tiara sensor array. On the third generation test vehicle, Tiara system includes 9 cameras and 2 lidar sensors. In the fourth largest model, the original 32 line velodyne ultra pucklidar is upgraded to 128 line alpha primelidar (also velodyne’s product). Alpha prime has a detection range of more than 200 meters and a field of view of 40 degrees. < / P > < p > in addition to the core Tiara system, Ford has also added rear-view sensors to the vehicle. All the roof cameras have been replaced with high-resolution models, and two of them have been moved back to work with the rear-view radar. < / P > < p > in addition to cameras and radars, the rear-view sensor package is also equipped with short-range lidar and near-field cameras. In addition, four short-range lidars and cameras are symmetrically installed in the new pod (at the front wheel arch). All these sensors work together to achieve a 360 degree field of view, covering 30-40 meters around. < / P > < p > in the third generation, Ford introduced the sensor cleaning system for the first time. Based on last year’s experience, Ford enhanced the system again with high pressure and new spray mode to achieve higher speed cleaning. In addition, the protective cover of the sensor is also coated with a new waterproof coating. < / P > < p > with more sensors and higher resolution, the processing capacity will be stronger. Although Ford and Argo did not elaborate on the choice of computing hardware, the CPU and GPU were customized from Intel and NVIDIA. < / P > < p > finally, Ford needs to prepare a stronger power supply to drive all this. To this end, Ford directly upgraded the battery pack of the escape hybrid. Ordinary commercial car batteries are only 1.1 kwh, but now they are upgraded to 1.5 kwh, and their power output is also higher. < / P > < p > at present, Ford’s fourth generation automatic driving model has been put into test, and will gradually become the backbone of Argo test team in the next few months. By next spring, residents of Miami, Austin, Washington, D.C., Pittsburgh and Detroit will be able to see them on the streets.
