Detailed Description
The technical solutions of the present application will be clearly and completely described below in connection with the embodiments, and it is obvious that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The application is realized by the following technical scheme:
an intelligent network-connected vehicle control method, comprising:
s1: the controller collects vehicle information;
the controller obtains and processes the current running information of the vehicle through a displacement sensor, a motor rotating speed sensor and the like to obtain related running data, and the related running data mainly comprise accelerator pedal displacement, an accelerator pedal displacement change rate and a motor rotating speed.
S2: judging the running state of the vehicle according to the pedal displacement change and the motor rotation speed and controlling the power output of the engine, specifically:
when the change rate A of the accelerator pedal displacement exceeds a preset threshold A 1 When the vehicle is judged to be in a state of needing larger acceleration in short time, the power output of the engine is provided at the moment;
when the accelerator pedal displacement B exceeds the set threshold B during the power output of the motor 1 And motor speed C is less than threshold C 1 When the vehicle is in a special road condition, judging that the vehicle is in the special road condition; providing an engine power output;
the special road condition is that the vehicle has larger resistance and needs stronger power to maintain the road condition of normal running, such as an ascending road section, etc.;
s3: adjusting the power output condition of the engine according to the running state of the vehicle and the power output frequency of the engine;
the method adjusts the preset threshold A by the number of times that the vehicle is in a state requiring larger acceleration in short time according to the vehicle positioning information and whether the vehicle is in a special road condition or not 1 The priority order is adjusted according to the times of the short time required larger acceleration state, whether the vehicle is positioned in a special road condition or not and the vehicle positioning information.
According to the short time requirement of the vehicleThe times of the larger acceleration state are used for adjusting the preset threshold A 1 The specific strategy of (a) is as follows: during time T, when the system determines that the vehicle is in the instantaneous high acceleration condition for a number of times greater than the frequency threshold N 1 When the system defaults that the driver has habit of high acceleration driving or the vehicle is in an environment where larger acceleration should be continuously carried out, the system automatically reduces the preset threshold A 1 The method comprises the steps of carrying out a first treatment on the surface of the Frequent switching of vehicle power is avoided;
during time T, when the system determines that the vehicle is in the instantaneous high acceleration condition for a number of times greater than the frequency threshold N 2 When N is 2 >N 1 The system defaults to the vehicle being in an environment where there is a continuous need for greater acceleration, the system is in period T 1 The power output of the engine is always kept in the engine, sufficient power is provided, and the frequent start and stop of the engine are avoided; during a period T when the system automatically maintains the power output of the engine 1 After the end, at time interval T 2 In this case, when the system determines that the vehicle again has a state in which a large acceleration is required, the system automatically starts the engine power output and the motor power output, and the duration is increased by Δt from the previous duration.
For example, assume a time interval T 2 1min, T1 was set to 3min, and ΔT was 30s, i.e., 0.5min. When the system judges that the vehicle is in a state of instantaneously needing larger acceleration again in the t+3+1, the vehicle automatically starts to keep the power output of the engine, and the current automatic duration is (3+0.5), and when the power output of the engine is ended, the time interval T after the end 2 In the process, when a state requiring larger acceleration occurs again, the vehicle automatically starts to keep the power output of the engine, the duration of the present time is (3+0.5+0.5), and so on.
When the system determines that the vehicle is in a special road condition, the system automatically switches to an engine power output state.
According to the vehicle positioning information, the power output condition of the engine is adjusted, and the specific strategy is as follows:

the present embodiment is exemplified by dividing the traffic flow and the number of vehicles into 2 location sub-areas:
the first location area is in an area range with a large number of vehicles and large people flow, and can be a school or a hospital; or near tourist attractions, trade areas, residential areas and the like;
the second location area is a region where the moving vehicles and the people flow are significantly reduced, and can be, for example, a region of a suburb, a part of a highway, etc. in the field.
When the vehicle is located in the first position area, the driver should reduce the driving speed or the required speed is lower, the driving requirement can be met without strong power output, and the system automatically increases the preset threshold A 1 Specifically, it can be represented by A 1 On the basis of the above, a certain fixed set value is added, so that the vehicle fully plays the clean energy advantage of the new energy power. When the vehicle positioning information is located in the second area, A can be properly lowered 1 。
In the method, all the threshold data can be set according to experience or combined with actual conditions in the initial setting process, and the method has the self-regulating capability, so that values can be randomly taken in a certain range during primary assignment, and the values are gradually and reasonably approached through automatic regulation of a system.
