Description

Technical Field

[0001] This invention relates to the field of remote control communication technology, and more specifically, to a two-way wireless remote control system and method for suspension damping control. Background Technology

[0002] In dynamic suspension damping control, the damping of each shock absorber hardware can be changed by the change of current. The vehicle's real-time onboard signals and sensor signals interact to collect a large amount of real-time road condition information. The CDC software calculates the current vehicle attitude based on this information. The debugging engineer decouples the software parameters according to the actual situation and obtains the optimal damping setting by combining algorithms or control strategies. Different current ranges correspond to different damping forces, and the vehicle's driving mode (comfort, sport, energy-saving, standard, etc.) is divided according to different current ranges.

[0003] During the debugging process, debugging engineers typically modify software parameters via a host computer or app and send commands to switch the vehicle's sport mode. The host computer and app are usually installed on a computer carried by the debugging engineer or on a handheld LCD screen. Alternatively, suspension sport modes can be switched via buttons or rotary switches, but like the host computer and app, these require connection to the circuit debugging communication harness. Furthermore, buttons and knobs only provide one-way communication and cannot return information on whether the vehicle's suspension is in the desired mode. When testing the vehicle suspension, various road surfaces are selected, causing the vehicle to experience bumps. While switching sport modes via a host computer or app provides two-way data interaction, it is inconvenient in practice.

[0004] Furthermore, although the method of switching suspension motion modes between the host computer and the APP can achieve two-way communication, it must be connected to the debugging communication harness and requires an external serial port or CAN communication line. Because the harness affects the freedom of operation for debugging personnel, it is inconvenient to operate manually on the computer or LCD screen when the vehicle is bumpy, which can easily lead to misoperation.

[0005] Furthermore, switching suspension modes via push-button or rotary switches requires external serial or CAN communication lines, which restricts operator freedom due to wiring constraints. This communication method is generally unidirectional, making it impossible to determine if the suspension mode switch was successful; sometimes, a host computer is needed for verification. It's also difficult to intuitively identify the suspension mode upon vehicle startup, typically requiring a default mode. Over time, drivers may forget the suspension mode, causing inconvenience and confusion for operators. Summary of the Invention

[0006] In view of this, the present invention provides a two-way communication wireless remote control system and method for suspension damping control, so as to facilitate the debugging personnel to debug the dynamic control of vehicle suspension damping.

[0007] To address the above technical problems, this invention provides a two-way communication wireless remote control system for suspension damping control, comprising:

[0021] On the other hand, the present invention also provides a two-way communication wireless remote control method for suspension damping control, comprising:

[0022] Remote control terminal, receiver terminal, main control unit and vehicle body; the remote control terminal and receiver terminal are integrated on the remote control transmitter, which is connected to the main control unit, and the main control unit is connected to the vehicle body.

[0024] The buttons are used for mode switching. The remote control has a first button, a second button, and a third button. Each button area is equipped with a corresponding mode indicator light.

[0025] The first wireless transceiver unit is used to receive circuit communication information from the receiver and convert it into electrical commands from the remote control.

[0026] The data processing unit is used to read key information and convert it into communication commands to be output, and send the communication commands through the first wireless transceiver unit; and to perform software decoding on the circuit communication information received by the first wireless transceiver unit from the receiving end to drive the LED indicator to switch on and off.

[0027] The second wireless transceiver unit is used to receive circuit communication information from the remote control terminal and send response information from the receiving terminal circuit.

[0028] The software decoding control unit is used to decode the information transmitted by the second wireless transceiver unit and to send response and / or instruction information through the second wireless transceiver unit to control the working state of the voice unit; then, it exchanges data instructions with the main control unit.

[0029] The main control unit is used to exchange data and commands with the receiving end and the vehicle ECU, and to control the hardware current output of the damping device to achieve dynamic control of the suspension damping.

[0030] The vehicle's ECU is an electronic control unit used to transmit vehicle operating data;

[0031] Its remote control method is as follows:

[0032] S1: Check the operating mode of the remote control. If it is in low power mode, activate it by pressing the first button. If not, proceed to step S2. When any button is pressed, the button indicator light shows the successful triggering status of the button.

[0033] S2: Determine whether a button is pressed within a preset time after the remote control is activated. If a button is pressed, proceed to steps S4, S5 and S6, but do not proceed to step S7. If no button is pressed, proceed to step S3.

[0034] S3: Enter automatic wake-up mode and low power mode; the automatic wake-up mode wakes up once every second and loops 100 times to check if there is a button trigger. If a button trigger is detected, proceed to steps S4, S5 and S6; if no button trigger is detected, proceed to step S7.

[0035] S4: Identify the triggering method of the button, including single click, long press, and no trigger;

[0036] When the button is triggered by a single click, the corresponding button indicator light illuminates, and the single click and long press event query loop count is reset to 100. After the command is sent, the remote control switches to receiving mode. If a response is received from the receiving end while in receiving mode, the corresponding mode indicator light illuminates and the current mode is announced via voice. If no response is received, the mode indicator light remains off, and the voice unit performs a strategy response. Then, step S2 is executed.

[0037] When the button is triggered by a long press, proceed to step S5;

[0038] S5: If a long press of the second button is detected, a mode query command is sent, and the number of button click and long press event query cycles is reset to 100; after the command is sent, the remote control switches to receiving mode; if a response is received from the receiver in receiving mode, the corresponding mode indicator light is turned on and the current mode is announced via voice; if no response is received, the mode indicator light remains off, and the voice unit performs a strategy response; then, step S2 is executed; otherwise, step S6 is executed.

[0039] S6: If a long press of the third button is detected, the button indicator light in the corresponding area will light up, exit and turn off the automatic wake-up mode, and proceed to step S1; otherwise, proceed to step S7.

[0040] S7: Repeat steps S4, S5, and S6 a preset number of times. If no button is triggered, stop the loop. Or, press and hold button 7 for 100 cycles, and the remote control enters the transmit mode, the button indicator light illuminates, and a mode query command is sent. After the command is sent, the remote control switches to the receive mode. If a response is received from the receiver in the receive mode, the corresponding mode indicator light illuminates and the current mode is announced via voice. If no response is received, the mode indicator light remains off, and the voice unit performs a strategy response. Then, step S3 is executed.

[0041] As an optional feature, the first button has a wake-up function and can be recognized as a single click and / or a long press; the second and third buttons can also be recognized as single clicks and / or long presses.

[0042] As an optional approach, the main control unit is equipped with a first CAN communication port and a second CAN communication port, which communicate with the receiving end and the vehicle ECU respectively. After receiving the mode switching information, the main control unit integrates the received vehicle operation data with the preset current range value for each mode to obtain the current output value of each suspension shock absorber hardware.

[0043] As an optional method, when the remote control sends a query command, the receiving end interacts with the main control unit. The main control unit transmits the current mode information to the receiving end, and the receiving end sends the mode information to the remote control through the second wireless transceiver unit. The remote control decodes the information and lights up the corresponding mode indicator light.

[0044] As an optional approach, each instruction transmission triggers the voice unit to broadcast a pattern, where the voice unit's strategy response is to broadcast abnormal communication information.

[0045] The beneficial effects of this invention are as follows:

[0046] 1. Freed from the constraints of connecting wires, it allows for remote control, providing greater operational freedom and ensuring personal safety in certain testing scenarios;

[0047] 2. The suspension mode switching is more convenient, and it is less likely to cause misoperation when the vehicle body is violently bumpy, making operation more time-saving and labor-saving;

[0048] 3. Data can achieve two-way interaction. The current mode can be determined in real time based on the LED light on the remote control transmitter. Combined with voice broadcast, it can be determined whether the current operation is successful. Other data information can also be judged through software program adjustments.

[0052] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to specific embodiments.

[0053] Example

[0054] Please see Figure 1 This embodiment provides a two-way communication wireless remote control system for suspension damping control, including:

[0055] The system includes a remote control unit, a receiver unit, a main control unit, and the vehicle body. The remote control unit communicates with the receiver unit, and the main control unit is connected to both the receiver unit and the vehicle body.

[0056] The remote control unit includes a first wireless transceiver unit, buttons, a data processing unit, and LED indicators; the receiving unit includes a second wireless transceiver unit, a software decoding control unit, and a voice unit; the vehicle body includes a body ECU and body suspension hardware circuitry; the LED indicators include button indicators and mode indicators. The body ECU is an electronic control unit used to transmit vehicle operating data, including but not limited to vehicle speed, steering wheel angle, brake pressure, and other vehicle information. The main control unit is used to exchange data and commands with the receiving unit and the body ECU, and to control the hardware current output of the damping devices to achieve dynamic control of the suspension damping.

[0057] Please see Figure 2 , Figure 2 This embodiment provides an optional remote control transmitter for use with the aforementioned system, representing a visual implementation of the remote control. The receiver can be configured as a circuit board mounted on one end of the vehicle body under test, establishing a transmission path with the vehicle's ECU according to preset electrical and / or communication connections. LED mode indicators 1, 2, 3, and 4 on the remote control transmitter correspond to different modes. The onboard antenna is located in area labeled 5, LED button indicator 6 is labeled 6, and buttons 7, 8, and 10 correspond to the first, second, and third buttons, respectively. This embodiment describes at least three buttons on the remote control, but the specific number is not limited. Please refer again. Figure 2 In this embodiment, a button labeled 9 is also provided. The four buttons correspond to four modes: comfort, energy saving, sports, and standard. These four buttons can be modified in the software to represent other data information as needed.

[0058] In this embodiment, the first wireless transceiver unit receives circuit communication information from the receiving end and converts it into electrical commands from the remote control end; the second wireless transceiver unit receives circuit communication information from the remote control end and sends response information from the receiving end circuit. Both the first and second wireless transceiver units use the CMT2300A RF chip manufactured by Huapu Microelectronics Co., Ltd., a domestic company. The CMT2300A chip is connected to the data processing unit in the remote control circuit via an SPI-like communication mode through its I / O port. The CMT2300A is an ultra-low power, high-performance OOK, (G)FSK RF transceiver suitable for various 127 to 1020MHz wireless applications. It supports multiple data packet formats and encoding / decoding methods, allowing it to flexibly meet the needs of various applications for different data packet formats and encoding / decoding. The CMT2300A operates from 1.8V to 3.6V. When reaching a sensitivity of -121dBm, it consumes only 8.5mA of current; the ultra-low power receiving mode further reduces the chip's receiving power consumption; at a 13dBm output, it consumes only 23mA of transmitting current.

[0059] The data processing unit is used to read key information and convert it into communication commands to be output, and then send the communication commands through the first wireless transceiver unit; it also performs software decoding on the circuit communication information received by the first wireless transceiver unit to drive the LED indicator to switch on and off. The data processing unit uses an STM32F103C8T6 chip, and completes information interaction with the first wireless transceiver unit through IO-simulated SPI communication mode, and parses the transmitted and received information through software decoding.

[0060] The software decoding control unit is used to decode the information transmitted by the second wireless transceiver unit and to issue response and / or command information through the second wireless transceiver unit to control the working state of the voice unit; afterwards, it exchanges data commands with the main control unit. Optionally, the software decoding control unit uses an MCU chip configured with a CAN interface. In this embodiment, the MCU chip is of the APM32F103RCT7 type from Jihai, which has two CAN interfaces.

[0061] Therefore, the main controller can exchange data and command information with the receiving circuit and the vehicle's ECU via the CAN communication port, controlling the hardware current output of the vehicle's shock absorbers, thereby dynamically controlling the suspension damping. This achieves remote control and adjustment.

[0062] Please see Figure 3 , Figure 3 The two-way wireless remote control method for suspension damping control provided in this embodiment includes the following steps:

[0063] S1: Check the operating mode of the remote control. If it is in low power mode, activate it by pressing button 7. If not, proceed to step S2. When any button is pressed, the button indicator light shows the successful triggering status of the button.

[0064] S2: Determine whether a button is pressed within a preset time, such as 5 seconds, after the remote control is activated. If a button is pressed, proceed to steps S4, S5, and S6, but do not proceed to step S7; otherwise, proceed to step S3.

[0065] S3: Enter automatic wake-up mode and low power mode; automatic wake-up mode wakes up once per second and initializes the key single and long press event query loop count to 100. Loop 100 times to check if a key is triggered. If a key is triggered, execute steps S4, S5 and S6; if no key is triggered, execute step S7.

[0066] S4: Identify the triggering method of the button, including single click, long press, and no trigger;

[0067] When the button is triggered by a single click, the corresponding button indicator light illuminates, a mode switching command is sent, and the single click and long press event query loop count is reset to 100. After the command is sent, the remote control switches to receiving mode. If a response is received from the receiver in receiving mode, the corresponding mode indicator light illuminates and the current mode is announced via voice. If no response is received, the mode indicator light remains off, and the voice unit responds according to the strategy. Then, step S2 is executed.

[0068] When the button is triggered by a long press, proceed to step S5;

[0069] S5: If a long press of button 8 is detected, a mode query command is sent, and the loop count for button click and long press events is reset to 100. After the command is sent, the remote control switches to receiving mode. If a response is received from the receiver while in receiving mode, the corresponding mode indicator light is turned on and the current mode is announced via voice. If no response is received, the mode indicator light remains off, and the voice unit responds according to the strategy. Then, step S2 is executed. Otherwise, step S6 is executed.

[0070] S6: If it is detected that button 10 has been pressed for a long time, the button indicator light in the corresponding area will light up, exit and turn off the automatic wake-up mode, and proceed to step S1; otherwise, proceed to step S7.

[0071] S7: Repeat steps S4, S5, and S6 a preset number of times. If no button is triggered, stop the loop. Or, press and hold button 7 for 100 cycles, and the remote control enters the transmit mode, the button indicator light illuminates, and a mode query command is sent. After the command is sent, the remote control switches to the receive mode. If a response is received from the receiver in the receive mode, the corresponding mode indicator light illuminates and the current mode is announced via voice. If no response is received, the mode indicator light remains off, and the voice unit performs a strategy response. Then, step S3 is executed.

[0072] In this embodiment, button 9 will only be recognized as a single click, while buttons 7, 8, and 10 can be recognized as both single clicks and long presses. There are three ways to send mode query information: 1. If button 7 is long-pressed 100 times without detecting any other button presses, mode query information will be sent. 2. If no button press is detected 100 times after entering automatic wake-up mode, mode query information will be sent. 3. Initially, automatic wake-up mode is not enabled, and the remote control is in low-power mode by default. Pressing button 7 exits low-power mode; maintaining a long press during this period will directly send mode query information. This design of button 7 is to handle the situation where the current mode needs to be directly queried after the initial wake-up.

[0073] The mode indicator light can turn on and off once per second. The remote control does not record mode information; it obtains the current mode information each time it receives information from the receiver. Each communication is considered a transmit / receive message. The receiver obtains mode information from the main control unit via CAN communication, and all wireless communication information is recorded in the main control unit. Each wireless communication triggers the receiver's voice unit, which can announce the current mode and abnormal communication information. In addition to determining the current mode from the mode indicator light on the remote control, the information announced by the voice unit can also be used to assist in determining the current mode.

[0074] Thus, using the above scheme, when the remote control sends a query command, the receiving end interacts with the main control unit. The main control unit transmits the current mode information to the receiving end, which then sends the mode information back to the remote control via the second wireless transceiver unit. The remote control decodes the information and illuminates the corresponding mode indicator light. If the main control unit receives mode switching information, it integrates the received vehicle operating data with the preset current range value for each mode to obtain the current output value of each suspension shock absorber hardware, facilitating the next step of the debugging process.

[0075] In implementing this embodiment, a button battery can be used to power the remote control transmitter at 3V. The data processing unit simulates SPI communication mode through the IO port to complete information interaction with the first wireless transceiver unit, and uses software decoding to parse the transmitted and received information. Then, it controls the LED indicator lights 1, 2, 3, 4, and 6 to turn on and off to indicate whether the button was successfully triggered. The data processing unit parses which button was pressed, then executes the operation command corresponding to that button, and activates the transmitting function of the first wireless transceiver unit to send command information. After the command is successfully sent, the receiving function of the first wireless transceiver unit is activated, the transmitting function is turned off, and the remote control is put into sleep mode, waking up once every once in a while to reduce power consumption.

[0076] Furthermore, the remote control is in low-power mode by default and can be woken up by a button or a timed automatic wake-up. Button 7 has a wake-up function. Press button 7 to wake up, then press button 8 to send mode switching information through the first wireless transceiver unit. Press and hold button 8 to send mode query information through the first wireless transceiver unit. In the wake-up state, if any button is pressed for 5 seconds without any operation, the timed automatic wake-up mode will be automatically activated, and the device will enter low-power mode. In this mode, it will exit low-power mode after 1 second, first performing a button-triggered query, and the query process will be executed 100 times. If no button is detected after 100 button presses or if no other button is detected after pressing button 7 for 100 times, mode query information will be sent, the corresponding mode indicator light will be lit, and the device will enter low-power mode again, and this cycle will repeat. Pressing and holding button 10 will exit the timed automatic wake-up mode, and the remote control will always be in low-power mode to reduce power consumption and extend battery life.

[0077] This embodiment frees operators from the constraints of wiring harnesses, allowing for remote control and greater operational freedom. It also enhances personal safety in certain testing scenarios. Furthermore, suspension mode switching is more convenient, reducing the risk of misoperation during severe vehicle vibrations, and saving time and effort. Additionally, data can be exchanged bidirectionally. The current mode can be determined in real-time by the LED lights on the remote transmitter, and voice prompts can indicate the success of the operation. Other data information can also be adjusted and evaluated through software.

[0078] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be considered as limitations on the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

If a response is received from the receiving terminal while in receiving mode, the corresponding mode indicator light is turned on and the current mode is announced via voice. If no response is received, the mode indicator light remains off, and the voice unit performs a strategy response. Then, step S2 is executed. Otherwise, step S6 is executed. S6: If a long press of the third button is detected, the button indicator light in the corresponding area will light up, exit and turn off the automatic wake-up mode, and proceed to step S1; otherwise, proceed to step S7. S7: Repeat steps S4, S5, and S6 a preset number of times. If no button is triggered, stop the loop; or if the first button is pressed and held for 100 cycles, the remote control enters the transmission mode, the button indicator light illuminates, and a mode query command is sent; after the command is sent, the remote control switches to the receiving mode; if a response information is received from the receiving end while in the receiving mode, the corresponding mode indicator light illuminates and the current mode is announced via voice; if no response information is received, the mode indicator light remains off, and the voice unit performs a strategy response; then, step S3 is executed.
