Road roller without cab
In September 2020, Liugong launched an intelligent unmanned road roller 6626E, which is a new member of Liugong’s many intelligent equipment, but what is different is that this time Liugong has thrown away the cab. .
Construction machinery is somewhat different from passenger cars. Generally, only the driver is in the cab. Since it is unmanned, the cab is simply cancelled.
This cab-less road roller can replace manual labor and can operate continuously around the clock to maximize user benefits; automatic obstacle avoidance, automatic route planning, automatic lane change, real-time monitoring of compactness; intelligent control compaction, high quality and efficiency.
The cab-less road roller is not the first of Liugong, and XCMG also demonstrated its cab-less road roller at the beginning of this year.
Machinery Finance believes that if unmanned driving is to be promoted in the field of construction machinery, road rollers are the most promising and relatively simple model.
First of all, the work of the road roller is single, and most of the time it travels in a straight line under the rated power. The flow and pressure of the hydraulic system such as the hydraulic vibration motor and the walking motor are also stable at a value.
Secondly, the working conditions are simple, the roads that press the road are smooth and barrier-free, and can be planned and managed to prevent other vehicles and people from entering. This reduces various obstacles in the operation of the roller.
The work is single and the working conditions are simple, so that the unmanned driving system of the road roller can be made very simple. It is not necessary to increase the panoramic camera and only use the millimeter wave radar to monitor the road conditions. External control to prevent people and vehicles from entering, then the unmanned driving only needs to plan the path for the roller, and then let it run at full capacity.
In short, the control system of the unmanned road roller can be relatively simple
Heavy truck without cab
In addition to the unmanned driving in the field of construction machinery, even the cab has been cancelled, several companies in the field of heavy trucks have also launched trucks without cab
In April 2017, FAW Jiefang officially released its “Zhitu” commercial vehicle strategy, and completed the field test of intelligent driving commercial vehicles for the first time, which attracted widespread attention in the industry. In October 2017, the L3 level smart truck was successfully tested on the highway. This is the first time that a Chinese commercial vehicle has completed a smart driving function test in a highway environment.
FAW’s heavy-duty truck without a cab is more like an automatic logistics truck. It has completely reinvented the original appearance of the truck, although it is currently only conducting conceptual tests in a port with a single road condition. But it has also taken an important step towards unmanned driving.
On September 24, 2019, Scania officially released the new driverless truck AXL. This fully autonomous concept truck was developed for mines and large enclosed construction sites. This concept truck does not have a cab.cv
As a milestone for Scania in the development of heavy self-driving trucks, even without a cab, Scania looks domineering.
Scania’s driverless and FAW’s design concept is very different. AXL retains almost all system assemblies except the cab, but realizes automatic control in operation. In fact, it can be clearly seen from the picture that the chassis of the Scania AXL self-driving truck is still from an ordinary dump truck. The front double steering axle adopts a drum brake axle, and the rear double drive axle adopts a Scania wheel-side reduction axle.
When it comes to heavy trucks without a cab, I have to mention Sweden’s EINRIDE Technology Company
EINRIDE has launched the first mass-produced unmanned truck, and this vehicle has now obtained a license for unmanned driving on the road in Sweden, which means that this truck can already achieve fully autonomous driving.
EINRIDE’s cab-less heavy truck is simply the Tesla of heavy trucks. It is a spoiler in the field of heavy trucks. Both the appearance and the automatic driving technology directly subvert people’s perception of heavy trucks. Although the current level of autonomous driving has not completely got rid of people, Einride’s T-Pod electric self-driving truck has reached the level of L4, second only to L5, and is the second highest level. At present, it can pass a few miles away. The operator of the company can monitor and control up to 10 trucks.
The Swedish manufacturer of Volvo Trucks has also launched a cabless heavy truck Vera, which is a self-driving truck that will operate in restricted areas such as ports and warehouse areas to transport heavy loads along fixed routes.
Machinery Finance Comments: These several non-driving heavy trucks are used in restricted areas to realize point-to-point logistics transportation. The selected area is also a place where road conditions and working conditions are relatively simple, such as Scania heavy trucks used in designated mining areas On the route, Einride is driving on a public road in an industrial area in Jönköping in central Sweden, and speed is also restricted. Volvo operates on a fixed route in restricted areas such as ports and warehouse areas.
However, we have to see that unmanned driving technology in the field of heavy trucks can also be completely without a cab, and only retain the carrying function of heavy trucks.
Unmanned Cab Tractor
In the article “5G + unmanned driving + hydrogen fuel cell + big data, tractors can also be tall” introduced a tractor independently developed by my country.
In order to realize the driverless function, ET504-H adopts advanced technologies such as mushroom GPS antenna, millimeter wave radar, and big data cloud platform.
The operator can plan the route on the tablet, and the ET504-H can run along the line. When there is an obstacle in front, it will actively sound the whistle to slow down and avoid the obstacle, without human intervention during the whole process.
Flexible obstacle avoidance
Driving on a planned route
This tractor is led by the National Agricultural Machinery Equipment Innovation Center and the tractor jointly built by the Luoyang Advanced Manufacturing Industry R&D Base of Tianjin High-end Equipment Research Institute of Tsinghua University. It combines 5G, unmanned driving, Beidou navigation, hydrogen fuel cell and other current cutting-edge technologies. When used, it really changed the silly temperament of agricultural machinery and pushed the tractor to the forefront of science and technology.
When everyone is focusing on unmanned driving technology on passenger cars, construction machinery, heavy trucks, and agricultural machinery are also secretly making efforts to avoid dragging their feet on unmanned roads, and Machinery Finance believes that compared with passenger cars, construction machinery , Heavy trucks, agricultural machinery may be easier to popularize unmanned driving.
First of all, working conditions. Construction machinery, heavy trucks, and agricultural machinery can find some very simple operating conditions and operating equipment, which reduces the difficulty of unmanned driving technology, reduces safety risks, and is easier to develop unmanned driving technology.
Second, demand. Construction machinery, heavy trucks, and agricultural machinery can find some large customers who have a relatively large demand for demanualization, such as ports, mines, and large farms. They have a relatively large willingness to popularize unmanned operations.
Finally, the special harsh environment. The high dust in the mine, the stench of the high-speed asphalt, and the dust and debris from the farm are all in a harsh environment, and there are hidden safety hazards. Many drivers no longer like to work in such an environment, which brings more to unmanned driving. Boost.
In summary, because construction machinery, heavy trucks, and agricultural machinery have some special working conditions and requirements, there is an objective and subjective willingness to popularize unmanned driving technology, so these areas may be the most thorough application areas of unmanned driving.
