[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0029] The utility model relates to the technical field of electric bicycle electronics and wireless communications, in particular to a vehicle controller for quickly copying parameters based on a Bluetooth device.

[0030] The vehicle controller for quickly copying parameters based on a Bluetooth device provided by the utility model is suitable for maintenance and debugging scenarios of electric bicycles.

[0031] Example 1

[0032] like Figure 1As shown, a vehicle controller parameter fast copy device based on Bluetooth device includes a vehicle controller and a

[0033] Input interface module 1, used to receive user operation actions;

[0034] Output interface module 2, used to indicate the current operation status and guide the user to perform parameter copy operations;

[0035] Bluetooth communication module 3, used to establish a Bluetooth link with the vehicle controller and transmit digital signals;

[0036] Memory module 4, used to store parameters of the vehicle controller;

[0037] Main controller module 5, used for executing the logic control of parameter copy;

[0038] The main controller module 5 is connected to the input interface module 1 , the output interface module 2 , the Bluetooth communication module 3 and the memory module 4 respectively.

[0039] like Figure 2 As shown, Bluetooth communication module 3 includes a search unit 31, a matching unit 32, and an HIC interface 34. Search unit 31 is used to scan and identify nearby Bluetooth devices; matching unit 32 is used to pair and connect with the identified Bluetooth device. A successful connection is achieved only when the vehicle controller and the controller with the adjusted parameters are the same model and system. HIC interface 34 is used to facilitate data exchange between main controller module 5 and Bluetooth communication module 3. In this embodiment, Bluetooth communication module 3 is a HY-40R201P, a Bluetooth 4.2 BLE protocol module based on the TI CC2640R2F chip. It features a programmable ARM-Cortex-M3 processor, which implements the functions of Bluetooth communication module 3 in this embodiment.

[0040] like Figure 2 As shown, the Bluetooth communication module 3 further includes a mode switching unit 33 for controlling the Bluetooth communication module 3 to enter the host mode or the slave mode; the mode switching unit 33 can switch between the host mode and the slave mode according to user operation actions.

[0041] Input interface module 1 includes a brake signal receiver, which receives signals generated by the user's braking action and converts them into electrical signals, which are then input to main controller module 5 to trigger or confirm the parameter copy operation. In this embodiment, the brake signal receiver is a Honeywell SS49E Hall-effect sensor, housed in a compact package. It is installed within the vehicle controller and connected to the electric vehicle's brake system via wires.

[0042] The output interface module 2 includes a buzzer for emitting sound to indicate the parameter copying status. In this embodiment, a non-LED buzzer with a model of YMZ16C-C1A-2, a mounting hole size of φ16 and a sound pressure of 75dB (1m) is used.

[0043] The memory module 4 includes a non-volatile memory unit, a storage management circuit, a cache unit and an interface circuit; the non-volatile memory unit uses a FLASH EPROM to store the parameter settings and firmware data of the vehicle controller; the storage management circuit is used to control the read and write operations of the data; the cache unit is used to temporarily store recently accessed data; and the interface circuit is used to connect the memory module 4 and the main controller module 5.

[0044] The main controller module 5 includes a central processing unit and an I / O interface. The central processing unit is connected to the input interface module 1, the output interface module 2, the memory module 4, and the Bluetooth communication module 3 through the I / O interface for data transmission. In this embodiment, the central processing unit adopts a Siemens S7-200 SMART series processor.

[0045] The main controller module 5 also includes a trigger timer, which generates a timing signal to control the time sequence of the copy process. In this embodiment, the trigger timer adopts an Agilent 53200 series radio frequency and universal frequency counter.

[0046] like Figure 1 As shown, the vehicle controller further includes a safety verification module 6 connected to the main controller module 5 for performing safety verification during the parameter copying process. In this embodiment, the safety verification module 6 adopts OMRON's G9SP safety controller, which has multiple safety input and output specifications.

[0047] like Figure 1 As shown, the vehicle controller also includes a log recording module 7 connected to the main controller module 5, for recording data information and operation during parameter copying. The log recording module 7 in the present embodiment uses the mode of STM32 mounting SD card record log, and STM32 is configured to mount TF card by CUBE to realize the recording and storage of data. STM32 is connected with the SD card module through its built-in SDIO interface, operates using HAL library function, and realizes the writing and reading of data.

[0048] When the utility model is in use, it is ensured that all modules, including the input interface module 1, the output interface module 2, the Bluetooth communication module 3, the memory module 4 and the main controller module 5, are correctly connected and installed in the vehicle controller.

[0049] Power on and start the vehicle controller with adjusted parameters, wait for 10 seconds, and the adjusted parameter controller will enter the slave mode. At the same time, power on and start the vehicle controller, let the main controller module 5 complete the self-test and initialize all connected modules, and start the Bluetooth communication module 3. Within the first 10 seconds of powering on and starting the vehicle controller, the user triggers the brake signal receiver in the input interface module 1 through the braking action, and it lasts for 3 seconds, then the mode switching unit 33 switches the Bluetooth communication module 3 to the host mode, automatically searches and scans the nearby adjusted parameter controllers in the slave mode, and identifies whether the model and system of the adjusted parameter controller are consistent with that of this controller. If they are consistent, use the matching unit 32 to pair and connect. After receiving the trigger signal, the main controller module 5 exchanges data with the Bluetooth communication module 3 through the HIC interface 34 and starts the parameter copy process. The central processing unit copies the parameters to the cache unit of the memory module 4. If the user triggers the brake signal receiver in input interface module 1 by braking for 3 seconds, the CPU will load the copied parameters into the original running memory, but will not overwrite the original parameters in the FLASH memory. The system will then enter driving mode to experience the effects of the copied parameters and wait for the user to confirm the operation. If the user triggers the brake signal receiver in input interface module 1 by braking for 10 seconds, the CPU will retain the copied parameters and overwrite the original parameters. Memory module 4 will ultimately save these parameters to the FLASH EPROM. Otherwise, the CPU will delete the temporary parameter data in the cache unit and FLASH EPROM and reload the original parameter settings.

[0050] When the vehicle controller is powered on, the buzzer emits a short beep to indicate the system is ready. When the vehicle controller is successfully paired with the parameter-adjusted controller, the buzzer emits two short beeps to confirm the Bluetooth connection has been established. When copying parameters begins, the buzzer emits a continuous, steady beep to indicate the copy process is in progress. After the parameter copy is complete, the buzzer emits a two-syllable beep-beep to alert the user that the copy process has been successfully completed. When user confirmation is required, the buzzer emits a single beep to request whether to retain or not retain the parameters. Before the system shuts down or resets, the buzzer emits a long beep to indicate that the system is about to shut down or reset. Additionally, if an error or abnormality occurs during the copy process, the buzzer emits a rapid, continuous beep to alert the user and allow them to take appropriate action.

[0051] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
