At the same time, both fuel economy and driving comfort requirements, there will be more automatic transmission assembly in the truck, there will be more than 60% of the survey forecasts 8 kind of car will use AMT, and more than 15% of the 8 trucks and more than 70% category 6 and 7 will be more and more use of hydraulic automatic transmission.

Peter bildt, chief engineer, believes that within three to five years, using active cruise technology, 3D GPS navigation maps and other technologies, the vehicle's fuel economy will be further improved by predicting terrain, which has been proven in the supertruck project.In a similar vein, navistar is moving in that direction.

Peter bildt expects the next phase of their project to take a leap forward in aerodynamics, trying to integrate the tractor and trailer, and optimize the flow of air between the tractor and trailer, underneath and behind the trailer, to achieve better fuel consumption.

Isuzu, which a few years ago had a lightweight, composite and aerodynamic body, is also embracing aerodynamic optimisation.The recession has forced a halt, but they believe the project will be supported and restarted in the near future.

At the same time, many truck manufacturers are using various technologies to achieve further fuel economy.They are trying to capture and improve even subtle factors that affect fuel economy in order to further optimize vehicle fuel consumption.

Volvo believes that the next phase of federal greenhouse gas emissions regulations will encourage the development of low-rolling tyres, and may even see such tyres mandated for use on roads, for example, where single tyres with wide sections are more widely used.

Navistar's horizon project concept car, unveiled at the 2013 mid-america truck show, demonstrated an intelligent dynamic intake grille system that can be turned on or off depending on the vehicle's cooling needs, meeting the vehicle's cooling needs while moving and reducing airflow resistance.

Engine idle stop function will continue to develop and continue to improve and optimize, we can even see the widespread use of solar idle stop system.

Auxiliary power units, auxiliary heater units, electric air conditioning systems, and automatic start-stop battery management systems are now widely used and will continue to be used in future trucks.In the survey, battery-powered, diesel-powered and even fuel-cell-powered systems are expected to play a major role in the future.

Feature 2: more optimized vehicle and engine efficiency

Logistics fleets are realizing that they can save fuel and lower upfront purchase costs by choosing smaller, more powerful, more application-friendly vehicles, and this trend will continue.For example, the current 13l-15l engine is used in the 8 class (total vehicle weight rated above 14,969 kg) road truck, and they hope that the engine engineers can develop the 11L engine to achieve the same working efficiency.

Class 5 international TerraStar medium truck

In medium-sized trucks, a lot of the team is gradually pour choose lower level vehicles, people are re-examining evaluating them, the power demand for trucks, they always used a level 6 (gross vehicle weight rating of 8846-11793 kg) or 7 (11794-14969 kg) rated gross vehicle weight truck and now they choose to level 5 (gross vehicle weight rating of 7258-8845 kg) of the truck, before they will always buy big enough heavy trucks to meet the power demand of security;Now they are considering how to choose more fuel-efficient vehicles for different transportation routes.

It is a trend to choose more suitable trucks for different working conditions to make the most of everything.Keep the load level at 90% and have more trucks than you do. If it's peak season, choose to lease the trucks you need.

五十铃表示,从以往传统的经验分析,如果车辆每年只有25000英里或者更少的运营里程,那么汽油机将是一个不错的选择,但是,现在却看到他们的客户一年运营里程在25000,30000甚至35000英里的,仍然表示可以接受汽油,因为相对于柴油机而言,汽油机不需要增加柴油为了满足排放要求各种尾气后处理成本。


●  特点五:驾驶室内部优化 更加舒适

未来的仪表板将会集成更多的车辆驾驶技术信息,福莱纳和彼得比尔特已经表示在概念车配备了可拆卸的平板电脑,它可以显示虚拟仪表,导航和瞬时燃油消耗和危险驾驶提醒功能。并且可以在车辆没有行驶,执行电子系统检查和其他驾驶愿驾驶的时候移除。

这项技术我们可以称之为转向补光技术,其实在乘用车领域很多车上已经配有AFS随动转向大灯功能,其目的和纳威司达概念车一样。而且此项技术已经非常成熟,对于没有AFS功能的车辆,随着CAN-BUS技术的快速发展,这个转向补光功能想要实现也非常简单,例如早期大众的速腾等车型,只需要通过VAS 5051或5053诊断仪进行简单的编码,就能让车辆在夜里转向的时候,转向侧的雾灯开启,以达到补光功能。对于国内卡车来讲这项技术很容易实现,但是当你看到有些车型连雾灯都没标配的时候,谈这个,的确有点遥远。

●  特点七:长头中卡遇冷 更多的平头中型卡车应用

日产扶桑卡车预测,将看到更多的平头中型卡车会在城市运输中广泛运用。事实上,目前已经有了越来越多的低平头中卡被广泛应用,相对于传统长头卡车,低平头卡车拥有更好的机动性,视线范围和城市运输效率。
