Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of a vehicle equipped with a driving cart according to an embodiment of the present invention, where the technical solution of this embodiment is applicable to a situation where a fuel power generation device is flexibly configured, the vehicle may be implemented in a software and/or hardware manner, and the vehicle may be formed by two or more physical entities, or may be formed by one physical entity.
Referring to fig. 1, the vehicle in the present embodiment includes: driving the vehicle 10; the driving vehicle 10 includes: a vehicle main controller 101, a hydrogen fuel power generation device 102 and/or an alcohol fuel power generation device 103, wherein the vehicle main controller 101 is respectively connected with the hydrogen fuel power generation device 102 and the alcohol fuel power generation device 103;
the vehicle main controller 101 is used for starting the hydrogen fuel power generation device 102 and/or the alcohol fuel power generation device 103 according to the vehicle running mode;
the hydrogen fuel power generation device 102 is used for converting hydrogen fuel into electric energy to generate electricity for the vehicle; the alcohol fuel power generation device 103 is used to convert alcohol fuel into electric energy to generate electricity for the vehicle.
In an embodiment, the vehicle travel mode includes: an alcohol power mode, an alcohol-hydrogen hybrid mode, and a hydrogen power mode. It should be understood that the vehicle travel pattern may be divided according to the fuel currently being used by the vehicle. Specifically, when the vehicle running mode is the alcohol power mode, the fuel adopted by the vehicle is alcohol fuel, and only the alcohol fuel power generation device is in the running state; when the vehicle running mode is an alcohol-hydrogen hybrid mode, the fuel adopted by the vehicle is alcohol fuel and hydrogen fuel, and the alcohol fuel power generation device and the hydrogen fuel power generation device are required to be in a running state; when the vehicle running mode is the hydrogen power mode, the fuel adopted by the vehicle is hydrogen fuel, and only the hydrogen fuel power generation device is in an operating state.
Of course, when the vehicle is in different vehicle travel modes, the corresponding fuel costs are also different. In other words, the vehicle driving modes can be classified into economy, normal, and environment-friendly according to the level of fuel cost. The economy type corresponds to an alcohol power mode, the ordinary type corresponds to an alcohol-hydrogen hybrid mode, and the environment-friendly type corresponds to a hydrogen power mode. It can be understood that the fuel cost corresponding to economy is the lowest, and the fuel cost corresponding to environment protection is the highest; it is also understood that economical emissions are the highest level of pollution, while environmentally friendly emissions are the lowest level of pollution.
In an embodiment, the vehicle driving mode is determined by the vehicle weight, the total mileage to be driven, the vehicle operating conditions, and the driving area. Of course, the vehicle weight, the total mileage to be driven, the vehicle operating conditions, and the driving area may be recorded as the current operating parameters of the vehicle. The vehicle bearing weight can be understood as the total weight of the cargo currently carried by the vehicle, and can be fixed or variable in the actual running process of the vehicle. For example, the departure point of the vehicle is a1, and the destination is B1, but the vehicle needs to unload part of the cargo at the transfer station C1 between the departure point a1 and the destination B1, and the vehicle has less load weight. The total mileage to be driven can be understood as the total route required for the vehicle to travel from the departure point to the destination.
In an embodiment, the total mileage to be traveled by the vehicle is counted to determine whether the vehicle is allowed to reach the destination by analyzing the current total amount of fuel remaining on the vehicle. If the destination can not be reached, the position information of the fuel supply station needs to be searched in time so as to supply fuel in time, and the situation that the destination can not be reached due to insufficient fuel is avoided. Of course, in order to detect the location of the fueling station in real time, the inquiry may be made by a Global Positioning System (GPS). Meanwhile, a display screen is installed in a carriage where a vehicle driver is located and used for displaying vehicle positioning information in real time, so that a user can know road condition information of a running road and position information of a nearby fuel supply station in time.
The vehicle running condition refers to the working condition of the vehicle in the running process. In an embodiment, vehicle operating conditions may be divided according to vehicle operating mode, driver control mode, and load conditions. For example, the operation mode of the vehicle can be divided into working conditions such as starting, accelerating, decelerating, turning, ascending and descending, parking and the like; according to the control mode of a driver, working conditions such as gear shifting, speed changing, sliding (gear-out sliding, neutral sliding, accelerating sliding and parking sliding), braking (emergency braking, speed control braking and brake braking), accelerator speed control, steering, reversing and the like can be respectively carried out; according to the load condition, the method mainly comprises the following steps: no-load, full load (equal to rated load), overload (exceeding rated load) and other operation conditions. In the actual driving process, the vehicle running condition is related to the road condition information of the vehicle driving road. Illustratively, when the road condition information of the vehicle driving road is an uphill road, correspondingly, in order to ensure the normal driving of the vehicle, the vehicle working condition needs to be adjusted to be accelerated; for another example, when the road condition information of the vehicle driving road is a curve, the vehicle condition needs to be adjusted to a curve.
In an embodiment, the vehicle main controller 101 may determine a vehicle running mode according to the current operating parameters, and activate the corresponding fuel cell according to the vehicle running mode. For example, when the vehicle is in the alcohol power mode, the vehicle may be switched to the alcohol-hydrogen hybrid running mode as the loaded weight of the vehicle increases, and for example, if acceleration running is required to arrive at a destination for delivery as soon as possible, the running mode of the vehicle may also be switched to the alcohol-hydrogen hybrid running mode. It can be understood that, during the running process of the vehicle, the vehicle main controller 101 can control the vehicle to switch among the three vehicle running modes at any time according to the current running parameters of the vehicle, so as to achieve the effect of reasonably distributing the fuel.
In the actual operation process, before starting the vehicle, the vehicle bearing weight, the total driving mileage, the vehicle operation condition, the driving area and other preset operation parameters need to be determined. The total distance to be traveled may be a distance from the departure point to the destination. In the actual operation process, the destination can be the destination of goods delivery, and can also be a refueling station. Wherein, the total mileage to be driven and the vehicle running condition of the vehicle are related to the driving route adopted by the user.
It should be noted that, in order to facilitate accurate statistics of the total amount of fuel consumed according to the vehicle operating conditions during the vehicle driving process, the route traveled by the vehicle may be planned through a big data technology and a GPS. For example, assuming that the user plans to go from the departure point A to the destination point B and there are N (N ≧ 6) driving routes between the departure point A and the destination point B, the total driving distance between the same departure point and the destination point may be different due to different driving routes. In order to accurately count the preset total fuel consumption, the driving route adopted by the user needs to be determined. Assuming that the user selects the travel route 6, various conditions in the travel route 6 that need to be passed are counted up by the GPS positioning, for example, a total travel distance required for the vehicle, an emission level of a travel area, road surface unevenness, and the like are counted up by the GPS positioning.
Specifically, the sum of the total amount of fuel required by the respective fuel power generation devices is a preset total amount of consumed fuel required by the vehicle. It is understood that the preset total fuel consumption amount may be understood as a total amount of fuel required for the vehicle from the departure point to the destination. Meanwhile, the preset total fuel consumption is in a functional relation with the vehicle bearing weight and the required total driving mileage. It is understood that the more the vehicle is loaded with weight, the more its corresponding preset total amount of consumed fuel; when the total driving mileage required by the vehicle is longer, the corresponding preset total fuel consumption amount is also larger. Of course, the preset total fuel consumption is also related to the vehicle operating condition. The running conditions of the vehicle can be divided into starting, accelerating, decelerating, constant speed or idling and the like; when the vehicle running condition is starting, decelerating, uniform speed or idling, the preset total fuel consumption amount is less, and conversely, when the vehicle running condition is accelerating, the preset total fuel consumption amount is more. For example, if the traveling distance from the departure point to the destination is a large number of uphill roads, the vehicle operation condition needs to be accelerated, and accordingly, the total amount of fuel required to be consumed is large. Of course, the preset total fuel consumption is related not only to the preset operating parameters but also to the vehicle model. Wherein, according to the vehicle load capacity, the vehicle can be divided into a micro card, a light card, a medium card, a heavy card and the like; vehicles can be classified into tractors, trailers, and the like according to the category of the vehicle. In the actual operation process, a display screen is configured in the head of the driving vehicle where the driver is located for viewing the running parameters of the vehicle and the related information of the vehicle in real time. It is understood that the driver can determine the model of the vehicle by inputting the license plate information of the vehicle on the display screen. For example, when the vehicle is a heavy truck, the vehicle weight is relatively the largest, and the corresponding trailer weight is also the largest, i.e., the total amount of fuel consumption is the largest.
After the vehicle model and the preset operation parameters are determined, the total fuel amount required by each fuel subsystem can be determined according to the vehicle bearing weight, the vehicle operation condition in the adopted driving route, the required total driving mileage and the emission level of the driving area. Wherein the fuel power generation device includes: an alcohol fuel power generation device and a hydrogen fuel power generation device. During the running process of the vehicle, when the vehicle adopts different preset operation parameters, the types of the fuels required to be consumed by the vehicle are different, and according to the classification of the fuel power generation device, the fuels required by the vehicle in the embodiment are hydrogen fuels and/or alcohol fuels. The hydrogen fuel is high in cost and is generally suitable for a driving area with high emission level of vehicles; the cost of the alcohol fuel is relatively low, and the alcohol fuel is generally suitable for the condition that the vehicle bears more weight or the vehicle runs under the condition of acceleration.
In the embodiment, the current operation parameters of the vehicle can be monitored in real time through each monitoring device in the vehicle during the running process of the vehicle, and the vehicle running mode is determined according to the current operation parameters. The driving mode of the vehicle can be determined according to the bearing weight of the vehicle, the total mileage to be driven, the running condition of the vehicle and the driving area. For example, when the vehicle carrying weight is empty, the vehicle running condition is starting and the emission level of the running area is low, the vehicle running mode can be determined to be economical (alcohol power mode); when the vehicle bearing weight reaches a preset bearing weight threshold (for example, the preset bearing weight threshold can be set to be 90% of the weight which can be borne by the vehicle), the vehicle operates in an accelerating mode, and the emission level of the driving area does not reach the preset emission level threshold (for example, the preset emission level threshold can be set according to pollutant emission standards), the driving mode of the vehicle can be determined to be a normal mode (alcohol-hydrogen hybrid mode); when the emission level of the driving region in which the vehicle is located is high, it is determined that the driving mode of the vehicle is the eco-friendly mode (hydrogen power mode). After the vehicle main controller 101 transmits a start instruction to the corresponding fuel power generation device, so that each fuel power generation device receives the start instruction, each fuel power generation device then starts its own control module to operate to convert its own fuel into electric energy by the power generation devices (the hydrogen fuel power generation device and the alcohol fuel power generation device) to perform power generation control on the vehicle to drive the vehicle to travel.
Certainly, the emission level of the driving area where the vehicle is located is related to the position information, for example, when the position information is in the urban area range and the emission level of the driving area is higher, the driving mode of the vehicle needs to be switched to the environment-friendly mode to reduce pollution emission and ensure the health of urban users; when the position information is in a suburban area and the emission level of the driving area is low, the driving mode of the vehicle can be switched to an economical type or a normal type so as to reduce the acquisition cost of the vehicle.
The technical scheme of the embodiment is that a vehicle main controller, a hydrogen fuel power generation device and/or an alcohol fuel power generation device are configured on a driving vehicle, the hydrogen fuel power generation device and/or the alcohol fuel power generation device are started by the vehicle main controller according to a vehicle running mode, if the hydrogen fuel power generation device is started, hydrogen fuel is converted into electric energy to generate power for the vehicle, if the alcohol fuel power generation device is started, alcohol fuel is converted into electric energy to generate power for the vehicle, if the hydrogen fuel power generation device and the alcohol fuel power generation device are started simultaneously, both the hydrogen fuel and the alcohol fuel are converted into electric energy to generate power for the vehicle, flexible configuration of each fuel power generation device according to the vehicle running mode is realized, thereby each fuel power generation device is switched to generate power, emission pollution of the vehicle is controlled according to the vehicle running mode, the vehicle can reach the destination under the full load condition, and the safety feasibility in the long-distance driving process is ensured.
Of course, when the vehicle needs to travel for a long distance, or the vehicle bears a heavy load, or the road is in a poor condition, in order to ensure that the fuel carried by the vehicle can allow the vehicle to reach the destination, a trailer can be lapped on the vehicle on the basis of the above embodiment. Fig. 2 is a schematic structural diagram of a vehicle equipped with a trailer and a driving cart according to an embodiment of the present invention.

In actual operation, the trailer 20 may be provided with the hydrogen fuel power generation device 102 or the alcohol fuel power generation device 103. Specifically, the type of the fuel cell power plant provided in the trailer 20 is related to the fuel cell power plant provided in the driver's vehicle 10 to which the trailer 20 is electrically connected. For example, when only the alcohol fuel power generation device 103 is provided on the driving vehicle 10, the hydrogen fuel power generation device 102 is provided on the trailer 20 in order to ensure that the vehicle can be switched to the hydrogen power mode; when the hydrogen fuel power generation device 102 and the alcohol fuel power generation device 103 are simultaneously arranged on the driving vehicle 10, the hydrogen fuel power generation device 102 can be arranged on the trailer 20; when only the hydrogen fuel power generation device 102 is provided on the driving vehicle 10, the alcohol fuel power generation device 103 may be provided on the trailer 20 in order to ensure that the vehicle can be switched to the alcohol power mode.
