Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the wide use of automobiles, a large amount of energy is consumed, the serious traffic jam problem, the environmental pollution problem and the like are often caused in the life scene of people, more and more troubles are caused to people, and the convenience of the automobiles is greatly influenced. In order to solve these problems, we need to perform specific analysis on specific scenes, and then solve specific problems. A very typical specific scenario of a problem is that, during driving of a vehicle, especially in a city, since a driver does not know the traffic condition of a road section to be reached, during passing through the road or during sudden turning of the vehicle, the vehicle may be subjected to relatively frequent operations, such as acceleration, deceleration, stopping and starting, which may cause a large waste of energy and exhaust emissions. Analysis of the Essen philosophy asset life-cycle cost structure shows that the purchase cost of a truck only accounts for 11% of the operation cost in the whole life cycle, but the oil consumption cost accounts for 30% of the operation cost, so that the energy consumption of the vehicle is controlled to be saved, the environment is protected, the energy is saved, and the driving cost is saved. In the prior art, the research on vehicle energy conservation is mainly carried out from two aspects of 'open source' and 'throttling'. But there has been no significant research effort. Meanwhile, researches show that when the vehicle is in an economical driving state, fuel oil can be saved by about 15% through operation of an accelerator, a gear and braking, and the fuel consumption of the vehicle is different by 2% -12% due to different driving habits. Even under the same conditions and with the same vehicle, the fuel consumption can be different by 15% -25% according to different operation levels of drivers. Therefore, the cultivation of the habit of the driver to operate the vehicle well is forced to be needed at the present stage. The invention provides a vehicle energy-saving processing method, which aims to solve the problems.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a vehicle energy saving processing method according to an embodiment of the invention. As shown in fig. 1, a vehicle energy saving processing method includes the steps of:
s101: presetting electronic map information;
the preset electronic map information includes, but is not limited to, an electronic navigation map and a high-precision map, and the preset electronic map information includes at least information data such as road curvature radius data, road gradient data, and road extending direction data. The expression form of the electronic navigation map is inclined to a structure of a 'directed graph', roads are abstracted into one edge, and the communicated relation of all edges forms the integral directed graph. Similar electronic navigation maps comprise a Baidu electronic navigation map, a Gauder electronic navigation map, a Google electronic map and the like; the navigation map is used for providing directional guidance for the driver, and specific identification marks on roads, complex conditions of entrances and exits, whether pedestrians are nearby and the like are judged by the driver. The absolute coordinate precision of the high-precision electronic map is higher. Absolute coordinate accuracy refers to the accuracy between an object on a map and a real world-outside thing. On the other hand, the road traffic information elements contained in the high-precision map are more abundant and detailed. The high-precision map can clearly help the driver to identify the geographic information, and the extremely high precision of the high-precision map is enough for the use of the unmanned vehicle.
The specific preset electronic map information may be one of an electronic navigation map or a high-precision map, or more than one kind of electronic map information may be preset at the same time. In this embodiment, a preset high-precision map is selected.
S102: acquiring vehicle information data;

It should be noted that the collected specific vehicle information data is collected according to specific needs, and the specific content of the driving data mentioned above is only an example and is not a limitation to the present invention.
S103: matching the vehicle information data with preset electronic map information to obtain road information data of the vehicle;

it should be noted that the vehicle driving strategy described in the present application includes, but is not limited to, the optimal driving speed of the vehicle, the engine output torque, the fuel injection output amount, and the like.
For example, the optimal vehicle running speed in the vehicle running strategy is calculated according to the road information data, the vehicle tire friction coefficient data (mu) is extracted from the vehicle information data and the road information data, and the road curvature radius data (r) is calculated according to the expression of the vehicle running strategy calculated according to the road information data to calculate the speed in the vehicle running strategy:
v2＝(μr)
wherein v is the speed in the vehicle driving strategy, namely the optimal driving speed of the vehicle;
if the vehicle speed information data is larger than the speed in the calculated vehicle running strategy, the running vehicle should be decelerated;
if the vehicle speed information data is smaller than the speed in the calculated vehicle running strategy, the running vehicle should be decelerated and accelerated;
and if the vehicle speed information data is equal to the speed in the calculated vehicle running strategy, maintaining the current vehicle running speed to continue running.
By considering the factors of economy, energy conservation and the like, a series of vehicle speed state quantities can be planned according to the gradient, curvature, speed limit and traffic scene information of the current road information data to meet the requirement of optimal economy. Exemplarily, when the vehicle turns, the speed of the vehicle is too large, the driver can step on the brake at the moment, the kinetic energy can be converted into the brake energy at the moment, the energy waste is caused, and the waste caused by the energy conversion can be avoided by controlling the speed of the vehicle in advance. And when the vehicle ascends a slope, judging whether the vehicle can stably ascend the slope according to the current speed and the power of the vehicle. When the output power is insufficient, the gear is switched in advance, so that the situation that a driver steps on the accelerator suddenly can be avoided. So as to achieve the purpose of vehicle energy conservation.
