Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and specifically to a system and method for integrating the vehicle's electricity with navigation path constraints for driving behavior. Background Art

[0002] With the development of technology, new energy vehicles have an increasing demand for intelligence. Regarding the driving range of electric vehicles, most of the driving range calculations are based on the power consumption at the user's driving speed. This calculation mode is seriously affected by the driver and road information and cannot solve the driver's range anxiety. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a system and method for integrating the vehicle's electricity with navigation path constraints for driving behavior, which can calculate the appropriate speed to complete the driving on the driving route according to the navigation path, can check whether the vehicle's electricity can support the completion of the driving, and can check the remaining electricity of the vehicle after the driving is completed.

[0004] To solve the above problems, the technical solution of the present invention is: A system for integrating the vehicle's electricity with navigation path constraints for driving behavior includes a calculation control module for controlling, receiving, and processing information. The calculation control module is connected to an information collection module for collecting driving route information and vehicle electricity information, an information display module for presenting the calculation results of the control module to the user, and an execution module for executing the power parameter values calculated by the control module.

[0005] Further, the calculation control module includes a vehicle control unit (VCU).

[0006] Further, the information collection module includes a battery management system (BMS), an in-vehicle infotainment system (IVI), and a vehicle-mounted communication system (T-BOX).

[0007] Further, the in-vehicle infotainment system (IVI) is also used as the information display module.

[0008] Further, the execution module includes a drive system motor control unit (MCU).

[0009] A method for integrating the vehicle's electricity with navigation path constraints for driving behavior includes the following steps:

[0010] (1) The user confirms to start navigation and inputs the destination information from the interface of the in-vehicle infotainment system (IVI) in the information collection module. The navigation system of the in-vehicle infotainment system (IVI) in the information collection module combines the positioning information of the communication system (T-BOX) in the information collection module, integrates the traffic lights, vehicle flow, and slope on the driving route, and sends them to the vehicle through the vehicle CAN network;

[0011] (2) In the calculation and control module, the vehicle control unit (VCU) in the vehicle control system combines the vehicle power information and navigation route information sent by the battery management system (BMS) and in-vehicle infotainment system (IVI) in the information acquisition module. By querying and calling the calibration data of the drive system MCU in the previous execution module and assuming a fuzzy algorithm that takes the intermediate value of the road condition information, it calculates the driving speed, driving time, and total power consumption. By comparing with the remaining power of the battery management system (BMS) in the current information acquisition module, it determines whether it meets the driving requirements and the remaining power information after driving. The vehicle control unit (VCU) in the calculation and control module of the vehicle control system feeds back the calculation results to the in-vehicle infotainment system (IVI) in the information acquisition module through the vehicle CAN communication;

[0012] (3) The user combines their own driving needs and selects the driving mode information fed back by the vehicle control unit (VCU) in the calculation and control module to the in-vehicle infotainment system (IVI) through the driving mode selection interface of the in-vehicle infotainment system (IVI) in the information display module. After confirming the selection, the in-vehicle infotainment system (IVI) sends the selection result to the vehicle control unit (VCU) through CAN communication;

[0013] (4) The vehicle control unit (VCU) in the calculation and control module calls out the corresponding power parameters of the driving mode calculated previously according to the driving mode confirmed by the user, controls the modification of the vehicle's power parameters, and the drive system MCU in the execution module executes according to the selected driving mode parameters, and the vehicle enters the navigation mode to ensure that the power consumption meets the customer's needs;

[0014] (5) During driving, the information acquisition module continuously collects the navigation path information and compares it with the currently running data. If the error is not greater than the threshold, no processing will be performed; if the error is greater than the threshold, steps (2) and (3) will be repeated until the user confirms the information result. The vehicle control unit (VCU) in the calculation and control module and the drive system MCU in the execution module confirm whether to execute according to the original driving mode or according to the result of step (4) based on the feedback from the in-vehicle infotainment system (IVI) 4 in the information display module.

[0015] The advantages of the present invention compared with the existing technology are as follows: According to the road information from the departure place to the destination and the vehicle power status in advance, the present invention calculates various driving modes and whether the vehicle can reach the destination and the remaining power under a certain driving mode. During driving, it calculates and corrects the currently selected driving mode according to the real-time road conditions. It presents to the driver in the most intuitive way, allowing the driver to clearly know the current remaining power, whether it meets the travel requirements of this trip, and which driving mode can maximize the satisfaction of the driving requirements of this trip.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment

[0019] As Figure 1 shown, a system for integrating vehicle power and navigating path to constrain driving behavior includes a computing control module for controlling, receiving, and processing information. The computing control module is connected to an information collection module for collecting driving route information and vehicle power information, an information display module for presenting the calculation results of the control module to the user, and an execution module for executing the power parameter values calculated by the control module. The information collection module, the information display module, the computing control module, and the execution module 4 are connected by a communication harness and can interact with each other for information.

[0020] The main function of the information collection module is to collect the driving route information and vehicle power information of the vehicle user to provide to the control module for calculating the driving model.

[0021] The function of the information display module is to present the calculation results of the control module to the user for the user to select and confirm, so that the user can clearly know the satisfaction relationship between the driving destination and the current remaining power.

[0022] The main tasks of the control module include controlling, receiving, and processing the signals of the information collection module, calculating and analyzing various driving models that currently meet the driving requirements, the remaining power, and controlling and modifying the driving mode of the entire vehicle to limit the driving power parameters.

[0023] The main task of the execution module is to execute the power parameter values calculated by the control module to drive the vehicle to travel.

[0024] As Figure 1-2 shown, the computing control module includes a vehicle control system VCU. The vehicle control system VCU is installed inside the vehicle compartment, detects the vehicle condition, communicates with vehicle components, and is used for calculating, selecting, and controlling the driving mode of the entire vehicle.

[0025] As Figure 1-2As shown in the figure, the information collection module includes a battery management system BMS, an in-vehicle infotainment system IVI, and an in-vehicle communication system T-BOX. The in-vehicle infotainment system IVI exchanges information with the vehicle control unit VCU and the in-vehicle communication system T-BOX. Based on the destination information input by the driver, the in-vehicle infotainment system IVI provides the vehicle control unit VCU with the road information for the driver's travel according to the positioning of the current location provided by the in-vehicle communication system T-BOX through its built-in navigation system. The vehicle control unit VCU calculates the driving mode based on the provided road information and feeds it back to the in-vehicle infotainment system IVI for the driver to select. The in-vehicle infotainment system IVI then feeds back the selection result to the vehicle control unit VCU for execution control. The battery management system BMS communicates with the vehicle control unit VCU to provide the current remaining battery power of the vehicle and the working current of other vehicle body components for the vehicle control unit VCU to calculate the driving mode model.

[0026] As Figure 1-2 shown in the figure, the in-vehicle infotainment system IVI is also used for the information display module. It calculates the driving mode and feeds it back to the in-vehicle infotainment system IVI, which then displays it for the driver to select.

[0027] As Figure 1-2 shown in the figure, the execution module includes a drive system MCU. The drive system MCU exchanges information with the vehicle control unit VCU. Based on the previous power calibration, the drive system MCU stores and plots the four-dimensional coordinates of the power model (voltage, current, speed, torque) for the vehicle control unit VCU to select the driving mode power and outputs power according to the instructions of the vehicle control unit VCU.

[0028] In specific use:

[0029] First, based on vehicle model parameters, power parameters such as voltage, motor speed, and torque, the power consumption data of the driving mode speed corresponding to these parameters can be calculated and analyzed, and these power parameter data are formed into a multi-dimensional matrix table and stored in the vehicle control unit VCU in the form of binary code for the vehicle control unit VCU to calculate, analyze, and call.

[0030] Second, the driver inputs the driving destination information through the in-vehicle infotainment system IVI. The built-in navigation system plans the best navigation route. The in-vehicle communication system T-BOX confirms the navigation positioning information and collects the road gradient information. The in-vehicle infotainment system IVI generates binary code of the navigation route information for the vehicle control unit VCU to analyze and calculate.

[0031] Again, the vehicle control unit (VCU) calculates multiple driving models based on the navigation information provided by the in-vehicle infotainment system (IVI), and collects the remaining power information provided by the battery management system (BMS) and the power requirements of other vehicle components currently.

[0032] Then, the in-vehicle infotainment system (IVI) receives the multiple driving models provided by the vehicle control unit (VCU) and displays them on the screen for the driver to select.

[0033] Finally, the vehicle control unit (VCU) distributes the mode parameters to the whole vehicle according to the driver's selected mode fed back by the in-vehicle infotainment system (IVI), and controls the drive system motor control unit (MCU) and the battery management system (BMS) to output and drive the vehicle to travel according to the model parameter instructions.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
