When it comes to smart or unmanned driving, it seems that few people associate it with commercial vehicles. Imagine a large truck with a load of several tens of tons moving fast on a highway. The driver's cockpit is not operated by the driver. The first impression may be very unsafe.
In fact, this is just a deviation in people's understanding. When passenger car manufacturers are rushing to release their vision of smart or driverless driving, as early as last year's Hannover Auto Show, Daimler demonstrated that it can be realized on the highway. The self-driving FutureTruck2025 (Future Truck) is known to be expected to be mass-produced by 2025.
“The inherent impression of commercial vehicles has affected the perception and understanding of new technologies on commercial vehicles to some extent,†said a commercial vehicle company who asked not to be named. Xu Baoping, president of Knorr-Bremse Commercial Vehicle Systems China, believes that “compared to passenger cars, commercial vehicles supplemented with smart driving technology can bring tangible efficiency gains and benefits.†He gave a report to the “First Financial Daily†reporter. As an example, if a commercial vehicle can achieve automatic driving on a special road segment such as a highway, the driver can use the leisure time to communicate more with the outside world. For example, telling the logistics center how much time is available for its own vehicles. In this process, the logistics center can prepare the goods to be delivered in advance, and the trucks can be loaded and shipped as soon as they arrive, greatly improving the logistics efficiency. At the same time, the addition of the driverless system can also reduce the driver's fatigue, thereby reducing operational errors and safety hazards caused by driver fatigue.
In Xu Baoping's view, from the technical point of view, the development of intelligent driving technology in the field of commercial vehicles is no less than the passenger car. For example, the lane departure warning system (which is based on advanced camera technology, which can continuously monitor the position of the vehicle in the lane marking and warn the driver when the vehicle exceeds this position) is being used in the passenger vehicle field. Commercial vehicle suppliers including WABCO are promoting. It is understood that WABCO has signed an intention cooperation agreement with Dongfeng, Yutong and BYD to equip the next-generation trucks and buses exported to Europe with WABCO's OnGuardACTIVETM emergency braking system and OnLane lane departure warning system.
"In fact, the whole unmanned process comes down to three parts. One is to perceive the external environment through radar, the other is to brake the whole vehicle when necessary, and the third is the steering system. If the three parts can be tacitly carried out, then the entire driverless process will be completed.†Xu Baoping told reporters, “At present, our driver assistance system can not only provide drivers with vehicle deviation warning, but also can do further Automatic brakes in case of emergency."
According to the introduction, this automatic brake system can provide different braking modes for the vehicle according to the speed. For example, the first stage may only provide the alarm function. If the alarm is not taken seriously, the vehicle will automatically decelerate. Brake if necessary.
As the world's largest commercial vehicle market, China's commercial vehicle market is in a critical period of transformation and upgrading. This provides a favorable opportunity for commercial vehicle suppliers to promote and popularize new technologies in China. For this reason, large parts suppliers such as Knorr-Bremse, China, and Bosch are accelerating the process of localization in the Chinese market, and innovative technologies based on intelligent driving are also recognized as important driving factors for future development.
However, even so, the large-scale promotion of intelligent and unmanned systems in the commercial vehicle sector will obviously lag behind passenger cars in time. “Technology promotion in the commercial vehicle sector is more subject to cost,†Xu Baoping explained. This is not the same as the passenger car is subject to regulations and infrastructure. However, in his view, if the passenger vehicle adopts the intelligent auxiliary system on a large scale, it will further shorten the time period of intelligent driving in the commercial vehicle field.
Woven wire screen mesh is woven with crimped wires, it normally used in the mining, coal, gravel, quarry, gabbro aggregate, slag, stone. It always be called square mesh wire cloth, Woven Wire Cloth screens, woven wire fabric or woven wire screens etc. This decoration wire mesh material should be high tensile steel wire, or manganese steel wire, and stainless steel wire. for this woven Quarry Screen Mesh, clients can choose material, wire thickness and other datas based on their own requirements.
Woven Mining Screen Mesh material:
Carbon steel wire, manganese steel wire, stainless steel wire etc.
Woven wire screen mesh wire diameter:
We can do from 1.2mm to 22mm above. All can be customized.
There are three types Vibrating Screen Mesh. Light types, middle type, and heavy types, these hole sizes for different wire diameter, according to the users` fact condition, choose different.
