[0062] In order to solve the problem of low actual utilization rate of electric scooters for the elderly, existing small new energy electric vehicles specially developed for the elderly are usually characterized by low speed, easy operation, high safety, etc., which are suitable for short-distance travel in small cities or suburbs; however, due to operational limitations, the adaptability of electric scooters for the elderly is not high compared to the elderly group.

It is usually necessary to set up other modules for reminders. During driving, it is easy to cause safety accidents due to lack of concentration on the normal operation of the electric scooter.

[0063] To solve the above technical problems, please refer to Figure 1 As shown, the present invention is a running control system for a new energy vehicle for elderly people, comprising:

[0064] A signal input unit is used to obtain the control command signal corresponding to each historical start and end route, and analyze multiple control command signals to obtain the operation control strategy; the start and end routes include the operation starting point, end point and operation direction line;

[0065] The speed control unit is used to start the automatic execution operation program of the current vehicle through the controller according to the operation control strategy, and output the vehicle speed control parameters in real time according to the automatic execution operation program; the vehicle speed control parameters include the speed control time point, the speed control number and the speed control road condition level; the speed control road condition level is set comprehensively according to the road surface flatness and traffic safety information;

[0069] If it is safe, continue to automatically execute the running program or interrupt the current program;

[0070] The display unit is used to display vehicle operating parameters.

[0071] In the above technical scheme, this embodiment designs the operation control system of the elderly mobility scooter by setting five parts, namely, a signal input unit, a speed control unit, an analysis unit, a fault feedback unit and a display unit, to achieve the design goal of stable operation, simple operation, safety and reliability of the elderly mobility scooter. In order to improve and promote the realization of this goal, the specific unit contents include:

[0072] Firstly, the present embodiment obtains the running track law of the mobility vehicle by setting a signal input unit, and obtains the corresponding control command signal according to the running data. Based on the high regularity of the daily life of the elderly, the frequency of activities in the surrounding environment is high, and the life in the surrounding city generally includes: shopping in the supermarket, seeing a doctor in the hospital, and going to the elderly activity places, and the routes of these activity areas are relatively fixed; the present design matches the corresponding according to its running law, obtains the running routes of several fixed activity places in the daily life of the elderly and obtains the control command signal corresponding to each route according to the running route analysis, forms an overall running control strategy of the control command signal, and ensures the accurate acquisition of the running analysis information such as the road conditions of the vehicle running law.

[0073] The specific implementation method is: by obtaining the control command signal corresponding to each historical start and end route, and parsing multiple control command signals, confirming and judging whether to start the current start control command signal to generate an operation control strategy through the analysis result of the control command signal; among them, according to the general operation rules of the new energy electric vehicle for elderly people's commuting and obtaining its start and end routes, the specific reference of the start and end routes that need to be obtained for the simulation operation of this embodiment includes the operation starting point, end point and operation direction line.

[0074] In order to achieve the above purpose, the process of analyzing, confirming and judging the control command signal to generate the operation control strategy in this embodiment is specifically as follows:

[0075] First, the actuator obtains the kinetic energy parameters, potential energy parameters, equipment temperature change, and equipment power consumption required for each start-end route; the actuator here mainly needs to obtain various parameters required by the vehicle during operation based on the statistics of the current start-end route. Therefore, the actuator of this design includes collecting data on its running execution equipment, and also needs to obtain the roadbed stability coefficient based on the kinetic energy parameters and potential energy parameters, and obtain the equipment performance coefficient based on the equipment temperature change and equipment power consumption.

[0076] Secondly, the real-time roadbed stability parameters and real-time equipment performance parameters of the vehicle in the continuous working cycle are collected to obtain the real-time operation control signal conversion value; by collecting the real-time roadbed stability parameters and real-time equipment performance parameters during the vehicle operation process, the real-time operation state of the current vehicle can be analyzed. Different operation states reflect different states of operation control signals. Therefore, based on the existing machine simulation algorithm, the real-time roadbed stability parameters and real-time equipment performance parameters are input into the control program to convert the operation control signal through simulation, and the operation control signal conversion value is output through the existing network model simulation;

[0077] Finally, based on the analysis of the real-time operation control signal conversion value, it is determined whether to start the control command signal and generate an operation control strategy.

[0078] In the above technical scheme, a signal input unit is set to obtain the running trajectory of the elderly scooter, so as to ensure that the corresponding control command signal is obtained according to the running data, and the basic running control signal under different routes is obtained according to the vehicle running status under different control command signals, and the signal is converted to ensure that a control strategy is formed for the current real-time trajectory signal, improve the accuracy of the combination of vehicle functions and actual running trajectories, and ensure the high adaptability of the elderly scooter new energy electric vehicle to the surrounding activity range of the elderly group.

[0079] As an implementation mode of the present invention, the method for obtaining the operation control signal conversion value in this embodiment is:

[0080] By formula Calculate and obtain the real-time operation control signal conversion value ;

[0081] in, is the number of continuous working cycles of the vehicle, ∈ ; For the Real-time roadbed stability parameters for consecutive working cycles; For the Real-time equipment performance parameters for a continuous working cycle; is the first conversion function; is the second conversion function; For the Route position coefficient for consecutive working cycles; is the preset time period, where 0< < .

[0082] In the above technical solution, the operation control signal conversion value is obtained to confirm the operation control signal range of the vehicle, and the specific real-time operation control signal conversion value is The acquisition is based on the periodic calculation and comprehensive acquisition of real-time roadbed stability parameters and real-time equipment performance parameters. The stable change of the operation control signal can be reflected through the roadbed stability and equipment performance, and the operation control signal conversion value is obtained according to the size of the stable change, so as to ensure the determination of the operation control signal range under the vehicle operation state, so as to further judge its rationality.

[0083] Among them, the first conversion function in the formula , the second conversion function All of them are obtained by fitting the test data under the normal operation of the current vehicle. Real-time roadbed stability parameters for consecutive working cycles and Real-time equipment performance parameters for a continuous working cycle , and then obtain the operation control signal conversion value under the position of the route of the current continuous working cycle by means of integral summation, and analyze the range of the position operation control signal.

[0084] As an implementation mode of the present invention, the size of the conversion value of the real-time operation control signal is determined:

[0085] Convert real-time control signals into values Conversion threshold interval with preset operation control signal To compare:

[0086] like ∈ , it is judged that the current vehicle operation reaches the control signal range and the control command signal is started;

[0087] like < , it is judged that the current vehicle operation does not reach the control signal range;

[0088] like > , it is determined that the current vehicle operation exceeds the control signal range, and a first warning signal is issued.

[0089] In the above technical solution, the determination of the operation control signal range in this embodiment is specifically: by converting the real-time operation control signal into a value The size is compared with the preset operation control signal conversion threshold interval, and the current vehicle operation is judged to exceed the control signal range based on the comparison result. The first signal warning notification is issued for exceeding the control signal range; the start control command signal is sent when the current vehicle operation reaches the control signal range.

[0090] As an embodiment of the present invention, the method for starting the control instruction signal to generate the operation control strategy is:

[0091] Collect the number of start control command signals of each working cycle under the current start and end route and the operation control signal conversion value corresponding to the start control command signal;

[0092] Obtain the change curve of the operation control signal conversion value of the start control command signal over time under all working cycles , and recorded as a set ;

[0093] Obtain the standard change curve of the operation control signal conversion value of the start control command signal over time under the same number of historical working cycles , and recorded as a set ;

[0094] Calculating Collections With Collection The coincidence degree of the curve that meets the standard change The ratio of the number of slope intervals to the total number;

[0095] Judgment Set With Collection Whether the overlap degree meets the standard threshold range:

[0096] If it meets the requirements, the automatic execution program will be started;

[0097] If it does not meet the requirements, debug the start and end routes.

[0098] In the above technical solution, according to further analysis of the operation control signal conversion value, firstly, by obtaining the operation control signal conversion value change curve of the start control command signal under all working cycles over time , and recorded as a set ; Then, obtain the standard change curve of the operation control signal conversion value of the start control command signal over time under the same number of working cycles in history , and recorded as a set Next, calculate the set With Collection The coincidence degree, that is, the curve that conforms to the standard change The ratio of the number of slope intervals to the total number; finally, the judgment set With Collection Whether the overlap degree meets the standard threshold range: if it does, the automatic execution program is started; if it does not, the start and end routes are debugged.

[0099] The operation control strategy is used to ensure whether the control state of the current vehicle operation state meets the requirements of self-operation, that is, by judging the dynamic change of the operation control signal conversion value under the current working state and the fluctuation range of the standard change, and then choosing the next step.

[0100] Secondly, this embodiment sets a speed control unit, which is used to start the automatic execution operation program of the current vehicle through the controller according to the operation control strategy, and output the vehicle speed control parameters in real time according to the automatic execution operation program; the vehicle speed control parameters include the speed control time point, the number of speed adjustments and the speed control road condition level; the speed control road condition level is set comprehensively according to the road surface flatness and traffic safety information. Different road conditions require speed adjustment, especially when performing automatic execution operation control. The factors affecting the vehicle control speed adjustment generally include road surface flatness, traffic volume, and changes in traffic operation rules, etc., and the corresponding speed adjustment processing is performed according to the real-time situation. The vehicle speed control parameters selected and obtained in this embodiment mainly include: the speed control time point, the number of speed adjustments and the speed control road condition level that can directly reflect the speed control status; and the real-time vehicle speed control parameters are output according to the historical settings during the automatic execution of the operation program.

[0101] As an embodiment of the present invention, please refer to Figure 2 As shown, the automatic execution program in this embodiment is:

[0102] Initialization start: The signal input unit interface calls the running starting point data, end point data and running direction line data of the current starting and ending routes, and the operating device sends a running instruction to the controller;

[0103] Start automatic operation: The controller receives the operation instruction, and the controller specifies the execution unit to call the speed PID control program to automatically operate the vehicle;

[0104] Start timer: obtain the three-dimensional simulation model of the vehicle's automatic operation state, input historical operation parameters for simulation, and determine the timing period according to the simulation results;

[0105] Interrupt request: Determine whether there is an interrupt request during the timing period:

[0106] If yes, the interrupt subroutine is executed to end the automatic operation;

[0107] If not, the current automatic operation will continue until the timing period ends.

[0108] In the above technical scheme, the intelligent control process is ensured according to the existing route conditions by automatically executing the operation program. Specifically, the initialization is first performed, and the operation starting point data, end point data and operation direction line data of the current start and end route are called through the signal input unit interface, and the operating device sends an operation instruction to the controller; the operating device here is mainly a device that can realize the operation of the wheels and generators of the vehicle, generally including buttons, keys and identifiers that can realize the movement of the vehicle at the operating handle; then the automatic operation process is started, including receiving the operation instruction through the controller, and the controller specifies the execution unit to call the speed PID control program to automatically operate the vehicle; further, the timer is started: a three-dimensional simulation model of the automatic operation state of the vehicle is obtained, the historical operation parameters are input for simulation, and the timing period is determined according to the simulation results. The three-dimensional simulation model here is obtained by simulation analysis based on ADAMS software, and by using ADAMS The system uses its own road and tire data files to simulate the driving conditions of the elderly scooter (turning, climbing, acceleration / deceleration), and makes corresponding evaluations on the simulation results. Then, the system uses existing machine learning methods to input historical operating parameters such as the operating route and operating speed for simulation, and outputs the time information from the start to the end of the operation. Finally, an interrupt request is set to determine whether there is an interrupt request within the timing period. If so, the interrupt subroutine is executed to end the automatic operation. If not, the current automatic operation continues until the timing period ends.

[0109] The above automatic execution running program can ensure that the elderly can operate the scooter in a normal environment, providing a more convenient "autonomous driving" program, but it is different from the "autonomous driving" feature of a fully automatically controlled motor vehicle. Usually, the program is started by confirming the button to ensure the daily route operation needs of the elderly. For the elderly, there is an additional simplified driving option. By simplifying the interface and the technical difficulty of handlebar operation, the possibility of safety accidents is reduced, and other operating obstacles in road operation are avoided to ensure driving smoothness. The above design can simplify the driving operation steps of new energy electric vehicles for the elderly and reduce the difficulty of operation.

[0110] It should also be noted that the automatic execution program is also equipped with a GIS system to obtain real-time route conditions to ensure that other roadblock information is predicted in advance.

[0111] Thirdly, the present embodiment sets up an analysis unit for obtaining a vehicle driving strategy based on a time-dependent trend analysis of the vehicle speed control parameters in a preset period of time. Since different speed control changes are set based on the overall road safety situation, the magnitude of the change also reflects the current safety changes in the surrounding environment of the vehicle, thereby ensuring real-time prediction of factors affecting safety accidents and elimination of fault factors during the driving operation of the automatic execution of the running program. By setting the vehicle driving strategy, it is ensured that the current change trend reflects the vehicle driving environment, and appropriate fault prediction and adjustment are made.

[0112] Specifically, as an implementation mode of the present invention, the vehicle driving strategy is:

[0113] Get the time-varying trend of vehicle speed control parameters during a preset period:

[0114]

[0115] in, The preset duration; is the preset weight coefficient, and >0; It is the real-time vehicle speed control parameter; Dynamic coefficient for vehicle speed control.

[0116] In the above technical solution, the dynamic coefficient of vehicle speed control is obtained by calculation through the formula , and by judging the dynamic coefficient of vehicle speed control The size is used to reflect the change in the vehicle operation range, and the safety of the vehicle operation environment is reflected according to the change in the vehicle operation range. Among them, the preset weight coefficient In order to select settings based on empirical data, adaptive adjustments can be made according to the specific vehicle operation and speed configuration.

[0117] Fourthly, this embodiment sets up a fault feedback unit to judge the safety of the current vehicle operating environment according to the vehicle driving strategy: if it is unsafe, an early warning notification is issued, and the current early warning notification is fed back to the signal input unit to adjust the start and end routes; if it is safe, the automatic execution of the running program continues or the current program is interrupted.

[0118] As an implementation mode of the present invention, a fault feedback unit is specifically provided:

[0119] The vehicle speed control dynamic coefficient The threshold range of the dynamic coefficient of vehicle speed control is preset To compare:

[0120] like < ≤ , it is judged that the current vehicle operating environment is relatively safe, and the automatic execution of the operating program continues;

[0121] like ≤ , then the current vehicle operating environment is judged to be safe, and the automatic execution of the running program continues, or the current program is interrupted;

[0122] like > , if the current vehicle operating environment is judged to be unsafe, a second warning signal is issued and the start and end routes are adjusted.

[0123] Fifthly, this embodiment provides a display unit for displaying vehicle operating parameters.

[0124] In the above technical solution, the display unit is used to display reminders, interruption reminders, manual operations and other display data of the vehicle's automatic execution of the running program, including brightness display, etc., to ensure the normal use needs of the elderly.

[0125] A control and display terminal for a new energy vehicle for elderly mobility commuters is a display terminal based on an operation control system of the new energy vehicle for elderly mobility commuters. The display terminal comprises a front display and a loudspeaker.

[0126] In the above technical solution, the display of the display terminal includes a display unit and a carrier of the corresponding display unit, etc.; a loudspeaker is also provided to remind the elderly with poor eyesight or hearing, thereby ensuring a certain safety reminder effect.

In particular, for the device, equipment, and non-volatile computer storage medium embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
