[0002] With the continuous increase in road traffic volume, vehicle driving safety has become an increasingly prominent issue, and the effectiveness of warning systems during emergency braking is directly related to driving safety. Currently, most vehicles' emergency braking warning systems rely primarily on the vehicle's existing electrical circuits or battery power, which has the following technical shortcomings:

[0003] Reliance on external power source: Traditional warning systems require connection to the vehicle battery or circuit, which involves complex wiring and occupies the vehicle's original resources. When the battery is low or the circuit fails, the warning function may fail, posing a safety hazard.

[0004] Insufficient response speed: Some systems trigger warnings via brake light signals, but there is a delay in signal transmission and processing, making it difficult to respond quickly during emergency braking, resulting in insufficient reaction time for drivers of following vehicles.

[0005] Limited warning effect: Traditional warning lights have poor brightness and synchronization, especially in bad weather (such as rain, fog, strong light) or complex road conditions, the warning effect is significantly reduced, and it is difficult to attract the attention of following vehicles.

[0006] Limited functionality: Existing systems mostly consist of independent warning lights, lacking multi-point linkage capabilities, and cannot achieve simultaneous warnings at different locations on the vehicle (such as the roof, rear, and sides), thus reducing the warning coverage area.

[0038] Figure 2 This is a circuit connection diagram of the control module of this utility model. Detailed Implementation

[0039] like Figure 1 Figure 2 As shown, this utility model discloses an intelligent vehicle emergency braking warning device based on solar power supply, comprising a solar power supply module, a control module, a wireless communication module, a sensor module, and a remote warning module. The solar power supply module is electrically connected to the control module to provide power to the control module. The sensor module is electrically connected to the control module to collect vehicle acceleration and vibration signals and transmit them to the control module. The wireless communication module is used to establish a communication connection between the control module and the remote warning module. The control module is used to control the local warning light and the remote warning module to issue warning signals based on the acceleration signals collected by the sensor module.

[0040] The solar power module includes a solar panel, a charging management chip, a lithium battery, and a power management module. The output of the solar panel is connected to the input of the charging management chip, the output of the charging management chip is connected to the input of the lithium battery, the output of the lithium battery is connected to the power management module, and the power management module is connected to the control module. The solar panel converts solar energy into electrical energy, the charging management chip manages the charging and discharging of the lithium battery to ensure a stable power supply, the lithium battery provides power to the entire device, and the power management module converts the voltage output from the lithium battery into the voltage required by the control module, providing a stable power supply to the control module.

[0041] The sensor module includes an acceleration sensor and a vibration sensor, both of which are electrically connected to the control module. The acceleration sensor monitors changes in vehicle acceleration in real time to determine if emergency braking has occurred (e.g., negative acceleration exceeding a set threshold). The vibration sensor detects vehicle vibration in real time to assist in determining emergency braking conditions (e.g., vehicle body vibration during sudden braking).

[0042] The control module includes a microcontroller, a warning light driver module, an LED warning light, and a data storage module. The warning light driver module and data storage module are electrically connected to the microcontroller, and the LED warning light is electrically connected to the warning light driver module. The microcontroller reads data from the sensor module in real time to determine if emergency braking conditions are met (e.g., acceleration < -0.5g and a high-level vibration signal). Based on the emergency braking conditions, it controls the LED warning light to operate via the warning light driver module and simultaneously sends a signal to a remote warning module via a wireless communication module. If emergency braking is detected, the warning light driver module immediately controls the LED warning light to flash and sends an ALERT_ON signal via the wireless communication module. If the vehicle deceleration ends, the warning light driver module immediately stops flashing and returns the LED warning light to standby mode, while simultaneously sending an ALERT_OFF signal via the wireless communication module. The data storage module records relevant emergency braking data to provide a basis for subsequent safety analysis.

[0043] The wireless communication module includes a wireless communication module one connected to the control module and a wireless communication module two connected to the remote warning module.

When microcontroller one detects emergency braking, it broadcasts an ALERT_ON signal, causing the remote warning module to synchronously trigger the warning light to flash.

[0044] The remote warning module may include one or more units, installed at different signal lights on the vehicle. It includes a microcontroller, a warning light driver module, and an LED warning light.

[0045] The device of this utility model also includes a manual control module, which is a button SW1. The button SW1 is electrically connected to the microcontroller and is used to issue a stop warning signal. When the user presses the button SW1, the microcontroller immediately stops the LED warning light from flashing and broadcasts an ALERT_OFF signal.

[0046] Key module selection:

[0047]

[0048] System workflow:

[0049] During normal vehicle operation (IDLE state): The solar panels convert solar energy into electrical energy and charge the built-in lithium battery via the charging management chip. Under normal driving conditions, the vehicle is in a stable state, and the acceleration and vibration sensors output low-level signals, which are transmitted to microcontroller one. Microcontroller one does not detect vibration signals exceeding the set threshold and does not issue any warning commands. LED warning lights one and two remain off, and the system is in monitoring standby mode.

[0050] During emergency braking (ALERTING): When the vehicle undergoes emergency braking, the acceleration sensor detects a rapid deceleration exceeding a set negative acceleration threshold. Simultaneously, the vehicle vibration sensor detects a vibration signal and outputs a high-level signal to microcontroller one. Microcontroller one reads the signal and determines it is an emergency braking state. It immediately sends a control signal to warning light driver module one, driving a high-brightness red LED warning light one to flash, and broadcasts an ALERT_ON signal via the wireless communication module. Upon receiving the ALERT_ON signal, the remote warning module's microcontroller two controls LED warning light two to flash, achieving synchronized alarm across multiple modules and sending warning signals to following vehicles. Simultaneously, the data storage module records relevant emergency braking data, providing a basis for subsequent safety analysis.

[0051] RECOVERING (Recovery Status) during system recovery: When the vehicle deceleration ends and button SW1 is pressed, microcontroller 1 receives the signal from button SW1 and determines that the emergency braking behavior has ended. It then broadcasts the ALERT_OFF signal through the wireless communication module. After receiving the ALERT_OFF signal, microcontroller 1 and all remote warning modules stop flashing LED warning light 1 and LED warning light 2, thus deactivating the warning status.
