Since 1984, the American association of truck technology and maintenance of the board of directors has been dedicated to the study the future development trend of the truck, they put forward a the opinions of the development of a period of time the truck we can clearly see from the inside the truck manufacturers and other industry company in the next five to 10 years or longer, trucks for the future development of a reasonable expectations.Eight technical features are summarized.

Feature 1: multiple technologies optimize for better fuel economy

Trucks in the United States association in the process of the technology and maintenance of the council's survey, more than half of the team think we will see in the investigation of tow truck fuel consumption will reach 9 miles per gallon (26 L per hundred kilometer) levels, or even better than this, there have been some teams even have reached this level, and transport company in the United States says it wants to see 10-15 miles per gallon of fuel consumption for tractor (relative to the 15.7 to 23.5 L per hundred kilometers).And they say it's not impossible in the field of tractors.

Peter bildt, a member of the U.S. department of energy's supertruck program, has focused on finding solutions to improve the efficiency of tractor-trailer freight.Peter bildt, chief engineer of the first generation of his "super truck" concept tractor-trailer, achieved fuel consumption of nearly 10 MPG (23.5l / 100km) and expects the second generation of trucks to have better performance when ready in the first quarter of 2014.It should be pointed out that the load - bearing mass in the United States is lower than that in China.

In addition to the needs of the fleet of transportation companies, the federal government's policies and regulations to reduce greenhouse gas emissions are driving the development of vehicle fuel economy in order to protect the environment.The first phase of regulations to reduce greenhouse gas emissions will be implemented on trucks in 2014, while more stringent regulations are being developed and are expected to be implemented in 2019.

To this end, truck manufacturers are constantly carrying out technological innovation.Reduce the demand of cruise power and reduce the engine displacement, carry out aerodynamic optimization on the cab, and further popularize the tractor after 6×2.

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.

Survey to dynamic control of trailer clearance and body height, lightweight materials and technology helps to save fuel and increase vehicle payload, we are likely to see vehicles in the future external antenna will disappear, these has has been applied on many vehicles, in addition a digital camera will replace the rearview mirror.These have been used in the flayner concept truck.

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.

● features three: a number of new technology applications more durable

In the future, trucks will be more reliable and oil change cycles will continue to increase, with more than 60,000 miles (96,560 kilometers) predicted, according to the survey.More and more teams are opting for pneumatic disc brakes, which require very little maintenance compared to traditional drum brakes.

In addition, 80 percent or more of the vehicles will be equipped with tire pressure monitoring and inflating systems, as well as tread depth sensors to help the tires last longer and save fuel.

Electrical equipment will continue to improve, with all LED lighting already in use on navistar's horizon trucks.

The use of computer technology and electronic vehicle inspection remote information processing system may play the greatest role during the normal running time of the vehicle.In the future, a more perfect truck remote information processing network will be built, through which vehicle data can be analyzed and judged to make the vehicle run more efficiently.

● feature four: diverse alternative fuels and gasoline are used

Volvo says alternative fuels will become very popular in the coming years, especially natural gas, and believes ethane and dimethyl ether fuels will be the future of choice.Hybrids, electric, propane, liquefied natural gas, will power future trucks.

相比较目前卡车大多数都采用柴油发电机作为动力,但是,在中型卡车中,未来我们将有可能会看到汽油发动机在6级(车辆总重额定8846–11793 kg)和7级(车辆总重额定11794–14969 kg)卡车上被应用。

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。
