step S10, surrounding environment information of a target vehicle is collected in real time, and road information is determined according to the surrounding environment information;
because the current automobile energy management solution does not consider the practical factors such as electric balance, NVH (Noise, vibration, harshness, noise, vibration and harshness), driving conditions and the like, when the automobile is running, an engine in the automobile cannot always run at an optimal efficiency point. Therefore, in this embodiment, according to the real-time road condition information, the lane information, the driving habit of the driver, the relations among the fuel consumption, the NVH, the electric balance and the power of the whole vehicle are more intelligently balanced, so that when the vehicle runs, the purpose of enabling the engine to always run at the optimal efficiency point and improving the energy-saving effect of the vehicle is achieved through continuous adjustment and optimization.
Therefore, in this embodiment, it is required to detect whether the target vehicle is in a running state, and detect and collect the surrounding environment information of the target vehicle in real time when the target vehicle is in a running state, where the manner of collecting the surrounding environment information of the target vehicle may be obtained according to a sensor installed in the target vehicle itself or may be obtained through third party software. And, the surrounding environment information may include road information, an area in which the target vehicle is located, and the like.
After the surrounding environment information is collected, the driving road driven by the target vehicle can be directly determined according to the surrounding environment information, the current situation of vehicle congestion in a certain range away from the target vehicle on the driving road is determined, and at the moment, the driving road driven by the target vehicle and the current situation of vehicle congestion can be used as road information. And because the target vehicle is in a motion state, the collected surrounding environment information is continuously updated, namely the current situation of vehicle congestion is continuously updated.
In another scenario, it is also possible to determine a driving road on which the target vehicle is driving and two side roads distributed on the left and right sides of the target vehicle based on surrounding environment information, and detect whether an obstacle (such as a vehicle, a pedestrian, or the like) exists within a certain range from the target vehicle in the driving road, the two side roads, and use it as road information. In a scene, a driving road on which the target vehicle drives is determined according to surrounding environment information, whether a traffic signal indicator lamp exists in front of the driving road is detected, and if the traffic signal indicator lamp exists, road information is determined according to the color of the traffic signal indicator lamp.
The road information comprises road condition information and lane information, the road condition information and the lane information can be obtained according to map information in a vehicle machine, and the road condition information can be information such as congestion, smoothness or speed limit.
Step S20, monitoring the opening degree of an accelerator pedal of the target vehicle in real time, and determining initial required power corresponding to the opening degree of the accelerator pedal;
in this embodiment, after determining road information near the target vehicle, the accelerator pedal in the target vehicle is monitored in real time, whether the accelerator pedal opening is updated is detected, if the accelerator pedal opening is detected to be updated, it is determined that the user is not satisfied with the running speed of the target vehicle at this time, the running speed of the target vehicle needs to be adjusted, after the user adjusts the accelerator pedal, the opening change rate of the accelerator pedal is obtained, the updated accelerator pedal opening is obtained, and the driver required power corresponding to the updated accelerator pedal opening, that is, the initial required power is determined. The mode of determining the driver demand power may be to set in advance a map of driver demand power corresponding to different accelerator pedal opening ranges, and determine the driver demand power corresponding to the accelerator pedal opening updated at the current time in the map. And it should be noted that, because there are two completely opposite actions of up-and-down adjustment of the accelerator pedal, when the updated accelerator pedal opening is obtained, the opening direction corresponding to the accelerator pedal opening is required, the positive and negative values of the driver demand power are determined according to different opening directions, and whether the whole vehicle power increase adjustment is required or the whole vehicle power decrease adjustment is required is determined according to the positive and negative values of the driver demand power.
The accelerator pedal opening is the opening of the accelerator pedal, namely the accelerator opening, the accelerator opening is the throttle opening, the throttle opening is controlled by the accelerator pedal, and the gasoline engine controls the fuel injection amount according to the throttle opening.
Step S30, determining the residual electric quantity of the target vehicle, and determining a target driving style according to the residual electric quantity and the road information;
after detecting that the accelerator pedal opening is updated and obtaining the updated accelerator pedal opening, the remaining capacity (i.e. the capacity for the vehicle) of the target vehicle at the current moment is required to be obtained, and the target driving style of the driver in the target vehicle is determined according to the updated accelerator pedal opening, the remaining capacity and the road information.
And step S40, adjusting the initial required power according to the target driving style to obtain target required power, and controlling the target vehicle to run according to the target required power.
In this embodiment, the driver demand power is obtained through the updated accelerator pedal opening, the demand power of the engine is determined according to the driver demand power, then the engine demand power gear is obtained according to the engine demand power and 5 engine power gear factors, and then the engine demand power (i.e. the initial demand power corresponding to the engine demand power gear) is adjusted according to the target driving style and the residual electric quantity of the target vehicle, such as the engine point position offset. And after the adjustment, when the target required power is obtained, the target vehicle is controlled to run according to the target required power.
It should be noted that, in this embodiment, a device for identifying and judging the driver style is further provided, the driver style is set to 10 levels in advance, the remaining power of the battery pack is also set to 10 levels, and then 5 engine power gear factors, namely "power following", "shutdown", "NVH", "north", "fast", are obtained according to the identified conditions of the target driver style and the remaining power of the target vehicle. And adding the five engine power gear factors to obtain target required power, namely an optimal efficiency point of the engine.
In addition, in the embodiment, when a driver needs high-power driving, the maximum power performance of the whole vehicle can be more intelligently exerted; when the driver needs better oil, the engine is more intelligently operated at the optimal oil consumption point, and the driver drives more smoothly, so that the engine is more intelligently maintained at the optimal NVH and the optimal efficiency point.
In the embodiment, road information is determined according to the collected surrounding environment information, initial required power is determined according to the monitored opening degree of the accelerator pedal, a target driving style is determined according to the residual electric quantity of the target vehicle and the road information, the initial required power is adjusted according to the target driving style to obtain the target required power, and the vehicle is operated according to the target required power, so that the problem that the engine cannot always operate at an optimal efficiency point due to the fact that the actual situation of the vehicle is not considered in the prior art is avoided, the phenomenon of low energy saving efficiency is caused, and the energy saving effect of the vehicle is improved.
Further, based on the first embodiment of the present invention, a second embodiment of the method for managing energy of an automobile of the present invention is provided, in this embodiment, step S20 in the foregoing embodiment, the step of determining the initial required power corresponding to the opening degree of the accelerator pedal is further refined, including:
step a, if the accelerator pedal opening is updated, determining the engine demand power according to the updated accelerator pedal opening;
in this embodiment, when it is detected that the accelerator pedal opening is updated, it is necessary to determine the required power of the driver of the driving target vehicle according to the updated accelerator pedal opening, and take the power of the engine corresponding to the driver required power as the engine required power. And in this embodiment, the correspondence between the driver demand power and the engine demand power may be set in advance.
And b, determining power values of all engine power gears in the target vehicle according to the engine demand power, calculating a sum of the power values of all the engine power gears, and taking the sum as initial demand power.
In this embodiment, it is necessary to set each of the engine power stages (e.g., "power follow", "stop", "NVH", "north", and "fast") in advance, and determine the initial value of each of the engine power stages in the current running state of the target vehicle. And determining whether the initial value of each engine power gear is required to be adjusted according to the engine demand power obtained by the updated accelerator pedal opening, if so, adjusting each initial value according to the engine demand power to obtain the power value of each engine power gear, calculating the sum of each power value, and taking the sum as the initial demand power of the target vehicle.
In this embodiment, after the accelerator pedal opening is updated and the corresponding engine power demand is determined, the sum of the power values of the power gears of each engine is calculated and is used as the initial power demand, so that the accuracy of the obtained initial power demand is ensured.
Further, the step of determining a target driving style according to the remaining power and the road information includes:
step c, determining all historical driving styles in a preset style driving list, and determining a matched driving style matched with the updated accelerator pedal opening in each historical driving style;
in this embodiment, when determining the target driving style, since a device for identifying and judging the driver style is set in advance in the target vehicle and the driver style is set to at least 10 levels, a style driving table with each history driving style may be constructed first, parameters such as the driver style, an electric quantity requirement range required by the driver style, a road requirement, and an accelerator pedal opening are set in the style driving table, and corresponding association relations are set between the parameters.
Then, a history driving style matched with the updated accelerator pedal opening is determined in each history driving style in the style driving table and used as a matched driving style.
And d, determining a target driving style according to the residual electric quantity, the road information and the matched driving style.
After the matching driving style is obtained, the residual electric quantity of the target vehicle and whether the road information of the road where the target vehicle is located meet the requirement of the matching driving style are detected, and the matching driving style is taken as the target driving style under the condition that the requirement is met.
In the embodiment, the target driving style is determined according to the residual electric quantity, the road information and the matched driving style by acquiring the matched driving style matched with the updated accelerator pedal opening in the style driving table, so that the accuracy of the acquired target driving style is ensured.
Specifically, the step of determining the target driving style according to the remaining power, the road information, and the matching driving style includes:
step e, determining an electric quantity demand range corresponding to the matched driving style, and determining whether the residual electric quantity is within the electric quantity demand range;

And f, if the residual electric quantity is in the electric quantity demand range, determining a target driving style according to the road information and the matched driving style.
When the residual electric quantity is found to be in the electric quantity demand range through judgment, the electric quantity of the target vehicle can be determined, and the target vehicle can be supported to run in a matched driving style. But at this time, it is necessary to consider the road information of the road on which the target vehicle is located, and take the matching driving style as the target driving style when the road information allows the target vehicle to perform the matching driving style. However, if the remaining power is not within the power demand range, the matching driving style is not taken as the target driving style, and the prompting information of insufficient power is output.
In the embodiment, when the residual electric quantity is in the electric quantity requirement range corresponding to the matched driving style, the target driving style is determined according to the road information and the matched driving style, so that the effectiveness of the obtained target driving style is ensured.
Specifically, the step of determining the target driving style according to the road information and the matching driving style includes:
step g, determining the road requirement corresponding to the matched driving style, and detecting whether the road information is matched with the road requirement;
in the present embodiment, it is necessary to determine the road demand corresponding to the matching driving style, such as the traffic flow of the road, the travel speed limit of the road, and the like. And detecting whether the road information acquired by the target vehicle is matched with the road requirement, and executing different operations according to different detection results.
And h, if the road information is matched with the road requirement, taking the matched driving style as a target driving style.
When the road information acquired by the target vehicle is judged to be matched with the road demand, the road information is determined to be just in the road demand range, namely, when the target vehicle runs, the road is in the road demand range, and the matched driving style can be directly used as the target driving style. However, if the road information and the road requirement are not matched, it is determined that the current road of the target vehicle is limited, and the target vehicle cannot be driven according to the matched driving style.
In this embodiment, when the road information is matched with the road requirement corresponding to the matched driving style, the matched driving style is taken as the target driving style, so that the effectiveness of the acquired target driving style is ensured.
Further, the step of adjusting the initial required power according to the target driving style includes:
step k, detecting whether the initial required power is in a power range corresponding to the target driving style;
in this embodiment, when the initial required power is adjusted, it is necessary to first detect whether the initial required power is within a power range corresponding to the target driving style.
And step l, if the initial required power is not in the power range corresponding to the target driving style, adjusting the initial required power according to the power range corresponding to the target driving style.
And when the initial required power is not in the power range corresponding to the target driving style, the initial required power is adjusted, namely 5 engine power gear factors are adjusted, and the sum of the adjusted power of the engine power gear factors is used as the adjusted initial required power, namely the target required power.
In this embodiment, when the initial required power is not within the power range corresponding to the target driving style, the initial required power is adjusted, so that the energy of the target vehicle is adjusted in real time, and the energy saving effect is improved.
Further, the step of determining road information according to the surrounding environment information includes:
m, determining a driving road on which the target vehicle drives in the surrounding environment information;
in this embodiment, when the road information is acquired, the driving road on which the target vehicle is driving in the surrounding environment information acquired in real time may be determined first, or the driving road and the two-side roads on the two sides of the target vehicle may be acquired.

If the number of other vehicles in the preset range is greater than the preset number, determining that the vehicle congestion level is congestion, and if the number of other vehicles in the preset range is less than or equal to the preset number, determining that the vehicle congestion level is smooth. And takes the vehicle congestion level as road information.
In this embodiment, the road information is obtained by determining the road on which the target vehicle travels, obtaining the congestion level of the vehicle within a preset range from the target vehicle, and using the congestion level as the road information, thereby ensuring the validity of the obtained road information.
