Description

Technical Field

[0001] The present invention relates to the technical field of automotive data storage, and particularly to a method, a system and a vehicle for storing the cruising range data of an intelligent connected vehicle. Background Art

[0002] The cruising range data of a new energy vehicle is an important display data of the vehicle. Usually, the driver will plan his travel plan and select a reasonable driving route according to the cruising range data of the vehicle. In order to accurately display the cruising range parameter of the vehicle, the vehicle controller will calculate the cruising range parameter of the vehicle in real time when the vehicle is powered on and update the display parameter. However, due to the limitation of the EEPROM write-erase times, usually only the latest cruising range parameter is sent to the EEPROM for storage when the vehicle is powered off. Before the next successful high-voltage power-on of the vehicle system, the cruising range parameter displayed by devices such as the instrument is the cruising range parameter stored in the EEPROM at the previous power-off. However, when the vehicle is abnormally powered off and does not complete the normal power-off process, it may cause abnormal storage of the cruising range parameter at power-off, which may further cause abnormal display of the cruising range parameter and also have a great impact on the calculation of other related parameters. This usually affects the driver's travel plan and driving route selection, brings a bad user experience to the vehicle owner, and further affects the brand image. To solve the above problems, the present invention proposes a new energy cruising range parameter storage, reading system and method. By widely collecting relevant patents and literatures, it is found that there are already many patented technologies for automotive data storage.

[0003] For example, a method for remotely monitoring the driving mileage of a hybrid vehicle disclosed in patent document CN102156471B processes the total vehicle mileage data by using the method of power-off storage and power-on reading. When the vehicle is powered on, the vehicle controller reads the total mileage of the vehicle at the previous power-off moment from the vehicle mileage storage area in the EEPROM. When the vehicle is powered off, the vehicle controller stores the total mileage traveled by the vehicle at the power-off moment in the vehicle mileage storage area.

[0004] Another example is a new energy vehicle driving data power-on / power-off storage system and control method disclosed in patent document CN109130866B. The key signal module provides power-on / power-off signals to the vehicle controller VCU. When the vehicle controller VCU reads the power-off signal, the vehicle controller VCU will store the current driving data of the vehicle in the data storage module EEPROM for calling when the vehicle is powered on next time; when the vehicle controller reads the power-on signal, the vehicle controller VCU calculates the cruising range of the vehicle under the current SOC according to the driving data provided by the data storage module EEPROM and displays it on the instrument in real time as the SOC changes.

[0005] For another example, the electric vehicle data storage device, its control method, and monitoring system disclosed in patent document CN111993891B propose a method for storing vehicle data and uploading vehicle data to a server at a specific fault moment of the whole vehicle. This method uses a battery management system to monitor the state of the vehicle's power battery in real time, generates a battery fault signal when the state of the vehicle's power battery is faulty, the vehicle controller is used to generate a control instruction according to the battery fault signal and the vehicle state, the remote communication module is used to obtain vehicle data according to the battery fault signal, store the vehicle data, and transmit the vehicle data to the server, thereby providing data support for subsequent fault analysis and fault determination.

[0006] The above three methods mainly use the method of storing when powering off and reading when powering on. This method can sufficiently meet the storage requirements of the cruising range parameters under normal power-on and power-off conditions of the vehicle. However, none of the above methods mention the impact of abnormal storage of the vehicle's cruising range data under abnormal power-on and power-off conditions. Cloud storage is usually used for big data storage and analysis, and cloud storage can only be realized when the network is in good condition. When the vehicle is in remote areas, basements and other places with poor signals, cloud storage cannot be realized. Improving the storage method of the vehicle's cruising range data under abnormal power-on and power-off conditions has a positive effect on improving the user experience and avoiding some abnormal calculations.

[0007] Therefore, it is necessary to develop a new storage method, system and vehicle for the cruising range data of intelligent connected vehicles. Summary of the Invention

[0008] The purpose of the present invention is to provide a storage method, system and vehicle for the cruising range data of intelligent connected vehicles to avoid abnormal display of the vehicle's cruising range parameters and related calculation anomalies under abnormal power-off conditions, and to improve the experience of the vehicle.

[0009] In a first aspect, a storage method for the cruising range data of an intelligent connected vehicle according to the present invention includes the following steps:

[0010] Step 1: When the vehicle is in a normal operation state with high-voltage power-on, the vehicle calculates the cruising range parameters of the vehicle in different modes, where the cruising range parameters at least include the total mileage;

[0011] Step 2: Determine whether the increase in the total mileage in this round reaches the preset storage interval mileage of the cruising range parameters. If it reaches the preset storage interval mileage of the cruising range parameters, send a cruising range parameter storage request flag bit to trigger external storage, send the cruising range parameters to the mobile phone for storage, and at the same time start the next round of mileage and time interval calculation; if it does not reach the preset storage interval mileage of the cruising range parameters, go to Step 3;

[0012] Step 3: Determine whether the time increment in this round reaches the preset storage interval time of the cruising range parameter. If it reaches the preset storage interval time of the cruising range parameter, send a flag bit for storing the cruising range parameter to trigger external storage, send the cruising range parameter to the mobile phone for storage, and at the same time start the calculation of the next round of mileage and time interval; if it does not reach the preset storage interval time of the cruising range parameter, return to Step 1;

[0013] Step 4: Detect in real time whether the vehicle has a power-off request. When it is detected that the vehicle powers off, send the cruising range parameter to the mobile phone for storage, and at the same time the vehicle terminal stores the cruising range parameter at the power-off moment; if it is not detected that the vehicle has a power-off request, return to Step 1.

[0014] Optionally, the calculation method of the total mileage increment is as follows:

[0015] Total mileage increment = total mileage calculated at the current moment - total mileage at the time of triggering external storage in the previous round;

[0016] If the vehicle has not triggered external storage after this power-on, the total mileage at the time of triggering external storage in the previous round is the total mileage stored at the last power-off moment.

[0017] Optionally, the calculation method of the time increment is as follows:

[0018] Time increment = current time - time at the time of triggering external storage in the previous round;

[0019] If the vehicle has not triggered external storage after this power-on, the time at the time of triggering external storage in the previous round is the time at the moment of this power-on.

[0020] Optionally, the sending the cruising range parameter to the mobile phone for storage is specifically as follows:

[0021] Step a1: When sending a request for storing the cruising range parameter, determine whether the Bluetooth of the in-vehicle terminal is connected to the Bluetooth of the mobile phone;

[0022] Step a2: When the Bluetooth of the in-vehicle terminal is connected to the Bluetooth of the mobile phone, the vehicle terminal sends the cruising range parameter to the mobile phone through the established Bluetooth connection; when the Bluetooth of the in-vehicle terminal is not connected to the Bluetooth of the mobile phone, the vehicle terminal sends the cruising range parameter to the TBOX, and the TBOX uploads the cruising range parameter to the cloud, and then synchronizes the cruising range parameter to the mobile phone through the cloud;

[0023] Step a3: The mobile phone receives the cruising range parameter and stores it in the mobile phone; during the data transmission process of storing the cruising range parameter, the priority of Bluetooth transmission is higher than that of cellular network transmission.

[0024] Optionally, in Step 1, it further includes:

[0025] When a vehicle power-on signal is detected, obtain the remaining mileage parameter stored on the mobile phone side and the remaining mileage parameter stored on the vehicle side, and determine the latest remaining mileage parameter according to the stored time and total mileage, which can ensure that the read remaining mileage parameter is more accurate.

[0026] Optionally, when the vehicle is in the power-off and sleep state, when the Bluetooth of the mobile phone side associated with the vehicle side is turned on and the distance between the vehicle side and the mobile phone side is less than the preset distance, the in-vehicle side and the mobile phone side automatically establish a Bluetooth connection.

[0027] The mobile phone side transmits the remaining mileage parameter stored on the mobile phone side most recently to the vehicle side through the established Bluetooth connection. Before the vehicle is powered on, the Bluetooth connection is automatically completed and data can be automatically obtained, which can improve the user experience.

[0028] Optionally, in step 1, calculate the remaining mileage parameter of the vehicle in different modes in real time according to the vehicle power battery power state, vehicle fuel state, and vehicle power consumption.

[0029] For pure electric new energy vehicles, the remaining mileage parameter includes pure electric driving range, remaining power, and total mileage.

[0030] For hybrid and range-extended new energy vehicles, the remaining mileage parameter includes pure electric driving range, remaining power, total mileage, fuel driving range, and remaining fuel.

[0031] In a second aspect, an intelligent network-connected vehicle remaining mileage data storage system according to the present invention includes a vehicle side and a mobile phone side.

[0032] The vehicle side and the mobile phone side establish a communication connection.

[0033] The intelligent network-connected vehicle remaining mileage data storage system is configured to be able to execute the steps of the intelligent network-connected vehicle remaining mileage data storage method according to any one of claims 1 to 3.

[0034] Optionally, the vehicle side includes an instrument, a CDC, a VCU, a TBOX, a BDC, an EEPROM, and an in-vehicle Bluetooth module. The VCU is respectively connected to the CDC, the EEPROM, the TBOX, and the BDC. The CDC is connected to the instrument, and the BDC is connected to the in-vehicle Bluetooth module.

[0035] The mobile phone side establishes a communication connection with the TBOX through the cloud, and the mobile phone Bluetooth module of the mobile phone side establishes a communication connection with the in-vehicle Bluetooth module.

[0036] The VCU is used to calculate the remaining mileage parameter of the vehicle in real time, send storage requests and data, and arbitrate the read parameters.

[0037] The TBOX is used to implement data transmission between the vehicle side and the cloud side;

[0038] The cloud side is used to receive data from the TBOX and forward it to the mobile phone side;

[0039] The in-vehicle Bluetooth module is used to receive data from the mobile phone side and send data to the mobile phone side;

[0040] The BDC is a relay for the communication signal between the VCU and the in-vehicle Bluetooth module;

[0041] The EEPROM serves as a local memory when the vehicle is powered off and stored;

[0042] The mobile phone side serves as an external memory for real-time storage;

[0043] The intelligent connected vehicle driving range data storage system is configured to be able to execute the steps of the intelligent connected vehicle driving range data storage method as described in the present invention.

[0044] In a third aspect, a vehicle according to the present invention adopts the intelligent connected vehicle driving range data storage system as described in the present invention.

[0045] Advantages of the present invention:

[0046] (1) Based on the power-off EEPROM storage and the external storage of the mobile phone side in the vehicle, external storage on the mobile phone side is performed according to the mileage change amount or the time change amount, that is, external storage is triggered every time the total driving mileage increases by a certain value; when the vehicle is in high-voltage activation and has a low speed or is stationary for a long time, external storage is triggered every certain time.

[0047] (2) When the vehicle owner approaches the vehicle with the mobile phone Bluetooth connected to the in-vehicle Bluetooth, the mobile phone will send the most recent driving range parameter stored in the mobile phone to the vehicle through the in-vehicle Bluetooth module. When the vehicle is powered on, the VCU will simultaneously read the data from the mobile phone Bluetooth and the data in the EEPROM memory, and obtain the latest driving range parameter through arbitration based on the storage time or the total mileage, and then send the arbitrated data to the instrument display or for other controller calculations.

[0048] (3) Selecting the total mileage as the basis for judging the interval mileage can avoid the judgment complexity caused by the variable driving range parameters of new energy vehicles. Selecting some important driving range parameters for external storage reduces the data transmission load and the load of the external mobile phone memory.

[0049] In summary, through the present invention, it is possible to effectively solve the abnormal storage of the remaining mileage parameter during power-off when the vehicle abnormally loses power and does not complete the normal power-off process without increasing the storage burden of the EEPROM. Compared with directly uploading data to the cloud for storage via the cellular network, it can avoid the adverse effects caused by network delay and poor network conditions, and at the same time ensure the efficiency of vehicle data storage and reading.

[0055] The following will illustrate the implementation manners of the technical solutions of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, rather than for limiting the protection scope of the present invention.

[0056] As Figure 2 shown, a method for storing the remaining mileage data of an intelligent connected vehicle includes the following steps:

[0057] Step 1: When the vehicle is in a normal operation state with high-voltage power on, the VCU calculates the cruising range parameters of the vehicle in different modes in real time according to the state of the vehicle's power battery, the state of the vehicle's fuel, and the power consumption of the vehicle. For pure electric new energy vehicles, among them, the cruising range parameters at least include the pure electric cruising range, the remaining power, and the total mileage. For hybrid and range-extended new energy vehicles, the fuel cruising range and the remaining fuel parameters are added as storage parameters on the basis of the above parameters.

[0058] Step 2: Determine whether the increase in the total mileage in this round reaches the preset cruising range parameter storage interval mileage (such as 5 km). If it reaches the preset cruising range parameter storage interval mileage, the VCU sends a cruising range parameter storage request flag bit to trigger external storage. The VCU sends the cruising range parameters to the mobile phone for storage, and at the same time, the VCU starts the next round of mileage and time interval calculation; if it does not reach the preset cruising range parameter storage interval mileage, go to Step 3.

[0059] Step 3: Determine whether the increase in time in this round reaches the preset cruising range parameter storage interval time (such as 5 min). If it reaches the preset cruising range parameter storage interval time, the VCU sends a cruising range parameter storage request flag bit to trigger external storage. The VCU sends the cruising range parameters to the mobile phone for storage, and at the same time, the VCU starts the next round of mileage and time interval calculation; if it does not reach the preset cruising range parameter storage interval time, return to Step 1.

[0060] Step 4: Detect in real time whether the vehicle has a power-off request. When it is detected that the vehicle is powered off, the VCU sends the cruising range parameters to the mobile phone for storage (trigger the Bluetooth or cellular network transmission module to transmit the cruising range parameters at the current moment to the mobile phone APP for storage), and at the same time, the vehicle stores the cruising range parameters at the power-off moment; if it is not detected that the vehicle has a power-off request, return to Step 1. That is, the external storage of the cruising range parameters is cyclically executed according to the mileage interval storage and time interval storage methods.

[0061] In this embodiment, the calculation method of the increase in the total mileage is as follows:

[0062] Increase in total mileage = total mileage calculated at the current moment - total mileage at the time of triggering external storage in the previous round;

[0063] If the external storage has not been triggered after the vehicle is powered on this time, the total mileage at the time of triggering external storage in the previous round is the total mileage stored at the previous power-off moment.

[0064] In this embodiment, the calculation method of the increase in time is as follows:

[0065] Increase in time = current time - time at the time of triggering external storage in the previous round;

[0066] If external storage has not been triggered after the vehicle is powered on this time, the time when external storage was triggered last time is the time of this power-on moment.

[0067] As Figure 3 shown, in this embodiment, the sending of the remaining driving range parameter to the mobile phone for storage is specifically as follows:

[0068] Step a1: When the remaining driving range parameter storage request flag bit sent by the VCU indicates a request, external data storage is triggered, and the VCU determines whether the Bluetooth of the in-vehicle device is connected to the Bluetooth of the mobile phone; during the data transmission of the remaining driving range parameter storage, the priority of Bluetooth transmission is higher than that of cellular network transmission.

[0069] Step a2: When the Bluetooth of the in-vehicle device is connected to the Bluetooth of the mobile phone, the VCU sends the remaining driving range parameter to the in-vehicle Bluetooth module through the BDC, and the in-vehicle Bluetooth module sends the remaining driving range parameter to the mobile phone APP through the mobile phone Bluetooth according to the Bluetooth communication protocol. If the Bluetooth of the in-vehicle device is not connected to the Bluetooth of the mobile phone, the VCU of the vehicle sends the remaining driving range parameter to the TBOX, and the TBOX uploads the remaining driving range parameter to the cloud, and then synchronizes the remaining driving range parameter to the mobile phone through the cloud;

[0070] Step a3: The mobile phone receives the remaining driving range parameter and stores it on the mobile phone.

[0071] As Figure 4 shown, the method for reading the remaining driving range parameter is as follows:

[0072] Step 1: When the vehicle is in the power-off and sleep state, when the vehicle owner approaches the vehicle with the mobile phone Bluetooth turned on, the in-vehicle Bluetooth module and the vehicle owner's mobile phone Bluetooth module will automatically connect.

[0073] Step 2: When the vehicle owner's mobile phone Bluetooth module is connected to the in-vehicle Bluetooth module, the mobile phone will transmit the remaining driving range parameter stored locally on the mobile phone most recently to the vehicle-related controller through the connected in-vehicle Bluetooth module and mobile phone Bluetooth module.

[0074] Step 3: The VCU continuously detects the high-voltage and low-voltage power-on signals of the vehicle. When the power-on signal is detected, the VCU reads the remaining driving range parameter from the in-vehicle Bluetooth module and the remaining driving range parameter from the EEPROM simultaneously.

[0075] Step 4: The VCU arbitrates the actual latest remaining driving range parameter according to the stored time and total mileage in the read remaining driving range parameter, and sends the latest remaining driving range parameter to the CDC and displays it on the instrument, and at the same time sends it to other controllers for use in the calculation of other parameters.

[0076] In this embodiment, the VCU arbitrates to obtain the actual latest remaining mileage parameter based on the stored time or total mileage parameter read from the remaining mileage parameter, specifically:

[0077] First, compare the remaining mileage parameters from the in-vehicle Bluetooth module and the remaining mileage parameters from the EEPROM. The larger total mileage is the latest stored remaining mileage data. When the total mileage is the same, judge the storage time, and the one with the closer storage time is the latest stored remaining mileage data.

[0078] As Figure 1 shown, an intelligent connected vehicle remaining mileage data storage system includes a vehicle side and a mobile phone side (with a vehicle control APP installed therein for receiving and storing remaining mileage parameters); the vehicle side and the mobile phone side establish a communication connection; the intelligent connected vehicle remaining mileage data storage system is configured to execute the steps of the intelligent connected vehicle remaining mileage data storage method described in this embodiment.

[0079] As Figure 1 described, in this embodiment, the vehicle side includes an instrument, a CDC (intelligent cockpit domain controller), a VCU (vehicle controller), a TBOX (in-vehicle communication controller assembly), a BDC (body domain controller), an EEPROM (electrically erasable programmable read-only memory), and an in-vehicle Bluetooth module. The VCU is respectively connected to the CDC, the EEPROM, the TBOX, and the BDC. The CDC is connected to the instrument, and the BDC is connected to the in-vehicle Bluetooth module. The mobile phone side establishes a communication connection with the TBOX through the cloud, and the mobile phone Bluetooth module of the mobile phone side establishes a communication connection with the in-vehicle Bluetooth module. Among them, the VCU is used to calculate the remaining mileage parameter of the vehicle in real time, send storage requests and data, and arbitrate the read parameters. The TBOX is used to realize data transmission between the vehicle side and the cloud. The cloud is used to receive data from the TBOX and forward it to the mobile phone side. The in-vehicle Bluetooth module is used to receive data from the mobile phone side and send data to the mobile phone side. The BDC is a transfer of the communication signal between the VCU and the in-vehicle Bluetooth module. The EEPROM serves as a local memory when the vehicle is powered off and stored. The mobile phone side serves as an external memory for real-time storage.

[0080] Through the above storage method, it is possible to effectively solve the abnormal storage of the remaining mileage parameter during power-off when the vehicle abnormally loses power and does not complete the normal power-off process without increasing the storage burden of the EEPROM. Compared with directly uploading data to the cloud for storage using a cellular network, it can avoid the adverse effects caused by network delay and poor network, and at the same time ensure the efficiency of vehicle data storage and reading.

[0081] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
