[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] like Figure 1-3 As shown, this application relates to a multi-functional indicator light control system. The multi-functional indicator light control system includes: a vehicle frame, on one side of which a multi-functional indicator light 10 is provided;
[0029] The light switch module 20 is located in the cab of the vehicle frame and is used to turn on various light signals. By selecting the side marker lights already installed on the original chassis as the multi-function indicator lights 10, there is no need to install new lights, thus avoiding increased costs and complex control circuits.
[0030] The vehicle body controller module 30 is electrically connected to the light switch module 20;
[0031] The vehicle controller module 40 is electrically connected to the body controller module 30; as a central controller, it is responsible for receiving signals from various parts of the vehicle, including driving status signals, charging status signals, intelligent charging status signals, etc., and controlling the on / off state of the multi-function indicator light 10 according to preset logic.
[0032] The relay controller module 50 is electrically connected to the vehicle controller module 40;
[0033] Specifically, the body controller module 30 collects the signal from the light switch module 20, converts the collected light hardwire signal into a CAN signal, and sends it to the vehicle controller module 40. The vehicle controller module 40 sends a high-level hardwire control signal based on the feedback electrical signal to control the relay controller module 50 to operate, so that the multi-function indicator light 10 is turned on or off.
[0034] Specifically, the frame, as one of the main structures of the vehicle, supports the installation and connection of multiple electrical modules and indicator lights. A multi-functional indicator light 10 is provided on one side of the frame to display different vehicle statuses.
[0035] The light switch module 20 is mounted on the vehicle frame or directly near the multi-function indicator light 10; this module allows the driver to manually control the on and off of different lights; the state of the light switch generates a hard-wired electrical signal indicating the driver's intention to operate the lights.
[0036] Body Controller Module 30 (BCM): The Body Controller Module 30 is directly electrically connected to the Light Switch Module 20; it collects the hard-wired signals from the Light Switch Module 20 and processes these signals.
[0037] The BCM converts these hard-wired signals into CAN bus protocol signals, enabling them to be transmitted and shared throughout the vehicle network. Different modules within the vehicle can receive these signals via the CAN bus, simplifying the vehicle wiring harness and enhancing the stability and reliability of signal transmission. The BCM then sends the converted CAN signals to the vehicle controller module 40, allowing the vehicle controller to perform corresponding control based on the driver's intentions.
[0038] Vehicle Controller Module 40 (VCU): The Vehicle Controller Module 40 receives the lighting CAN signals sent by the BCM. Its responsibility is to analyze the CAN signals, determine the status of the lighting signals, and decide on the next step.
[0039] The vehicle controller sends commands to the relay controller module 50 based on the lighting signals, causing it to perform corresponding actions. For example, if it receives a signal to turn on the turn signal, the vehicle controller will issue a control command so that the relay controller module 50 activates the circuit for the corresponding light.
[0040] The relay controller module 50 is connected between the vehicle controller module 40 and the multi-function indicator light 10; according to the instructions issued by the vehicle controller, it controls the multi-function indicator light 10 to turn on or off.
[0041] For example, when the vehicle controller module 40 issues an "on" command, the relay controller module 50 connects the circuit to illuminate the multi-function indicator light 10; if the command is "off", the relay controller module 50 disconnects the circuit to turn off the light.
[0042] System workflow summary:
[0043] When the driver operates the light switch, the light switch module 20 is triggered, generating a corresponding hard-wired signal.
[0044] BCM acquires and converts signals: Body Controller Module 30 (BCM) receives the hardwired signal and converts it into a CAN signal.
[0045] VCU Analysis Command: The vehicle controller module 40 receives the CAN signal, parses it, and sends a command to the relay controller.
[0046] Light control: The relay controller module 50 controls the on / off state of the multi-function indicator light 10 according to the instructions, so that it lights up or turns off.
[0047] This application proposes a multi-functional indicator light 10, which not only redefines the function of the side marker lights on the original vehicle chassis, but also realizes multiple functions such as driving indication, charging status indication and intelligent charging indication through intelligent control of the vehicle control unit (VCU). It eliminates the need to add additional indicator lights, effectively reducing costs and improving the vehicle's intelligence level.
[0048] The left front chassis light is used as a multi-functional indicator light and is independently controlled. This indicator light is controlled by the parking light signal (message, sent by BCM), the high-voltage charging status signal, and the intelligent charging status signal. A label is added to indicate: when the light is OFF, it indicates that the vehicle is under high voltage and you should not repair the vehicle to avoid electric shock.
[0049] As can be seen from the above description, this application achieves the following technical effects:
[0050] In this embodiment, an indicator light is used to display different states. The body controller module 30 collects signals from the light switch module 20 and converts the collected light hardwire signals into CAN signals, which are then sent to the vehicle controller module 40. The vehicle controller module 40 issues control commands based on the feedback electrical signals to control the relay controller module 50 to operate, thereby turning the multi-functional indicator light 10 on or off. This achieves the purpose of multi-functional indicator light display, thus reducing production costs and meeting diversified usage needs. It also solves the technical problem that existing new energy commercial vehicles have a wide variety of indicator lights, which increases manufacturing costs and maintenance difficulty. Furthermore, traditional indicator lights have limited functions and cannot meet the diversified information display needs of new energy vehicles in terms of charging status, intelligent charging status, high voltage status, and nighttime indication status.
[0051] Furthermore, it also includes a power battery management module, which is electrically connected to the vehicle controller module 40. The power battery management module is used to monitor the charging status of the power battery and send the charging status signal to the vehicle controller module 40.
[0052] Specifically, the Battery Management System (BMS) is directly connected to the battery and is responsible for monitoring several key battery parameters in real time, including but not limited to: State of Charge (SOC): the current remaining percentage of battery charge; Charging voltage and current: ensuring that charging and discharging currents are within safe ranges; and Temperature monitoring: preventing the battery from overheating or becoming too cold.
[0053] The power battery management module collects these parameters and comprehensively analyzes the battery's status and health condition, thereby providing accurate charging status information.
[0054] Once a change in charging status is detected, the BMS will generate a corresponding signal and send this status signal to the vehicle controller module 40 via the CAN bus or other communication methods.
[0055] Vehicle Controller Module 40 (VCU): This module serves as the central control unit of the vehicle and is responsible for receiving signals from various sub-modules, including the power battery management module.
[0056] After receiving the charging status signal from the BMS, the VCU can adjust the vehicle's energy management strategy accordingly. For example, when the battery level is low, the VCU can trigger a low battery warning or limit some of the vehicle's high-energy-consuming functions to extend the driving range.
[0057] When the battery is near full charge or the temperature is too high, the VCU may limit the charging current to protect the battery.
[0058] The VCU can also provide charging reminders to the driver or adjust driving modes when the battery is in a suitable charging state to optimize battery usage and range performance.
[0059] The workflow of the power battery management module is as follows:
[0060] Battery monitoring: The BMS monitors the battery's charging status, temperature, voltage, current, and other information in real time.
[0061] Status signal transmission: When the charging status changes, the BMS will generate a status signal and send it to the VCU via an electrical connection (usually CAN communication).
[0062] VCU parsing and response: The VCU receives and parses the charging status signal and makes control adjustments based on the current battery status (e.g., limiting energy consumption, triggering warnings, and optimizing driving modes).
[0063] Information feedback: When necessary, the VCU will feed back key battery status information to the driver interface or work in conjunction with other system modules.
[0064] Furthermore, it also includes an alarm module, which is electrically connected to the vehicle controller module 40. It is understood that this enables a good alarm effect, thereby improving safety.
[0065] Furthermore, the multi-functional indicator light 10 includes: driving indicator light status, charging indicator light status, and intelligent charging indicator light status. It can be understood that it can display multiple statuses.
[0066] Specifically, 1. Driving indicator light mode:
[0067] When the driver turns the headlight switch to the parking light position, the BCM receives the parking light activation signal from the headlight switch, converts it into a message signal, and sends it to the VCU.
[0068] After receiving the parking light status message, the VCU immediately recognizes it as a signal to start the driving indicator light mode.
[0069] The VCU sends a lighting command to the multi-function indicator light 10 via the relay controller, and the multi-function indicator light 10 then lights up as a driving indicator light, improving driving safety at night or in low visibility conditions.
[0070] 2. Charging indicator light mode:
[0071] During the charging process of the power battery, the BMS continuously monitors the charging status and sends the charging status signal to the VCU in real time.
[0072] After receiving the charging status signal, the VCU determines whether it is currently in a charging state.
[0073] If the charging status is confirmed, the VCU will illuminate the multi-function indicator light 10 via the relay controller to serve as a charging indicator, allowing the driver and charging personnel to intuitively understand the charging progress.
[0074] 3. Intelligent power replenishment indicator mode:
[0075] When the vehicle starts the intelligent charging program, the VCU will receive a charging start signal from the vehicle's low-voltage lithium battery.
[0076] After confirming that the power-charging procedure has been initiated, the VCU will control the vehicle's high-voltage system to enter a ready state. Simultaneously, the VCU will illuminate the multi-function indicator light 10 via the relay controller, serving as an intelligent power-charging indicator light to notify the driver or maintenance personnel that the vehicle is undergoing intelligent power-charging operation, ensuring the safety and transparency of the process.
[0077] This utility model also has the following beneficial effects:
[0078] 1. It has significant technological advantages and application prospects in the field of new energy commercial vehicles, and can effectively reduce vehicle manufacturing costs, improve the level of intelligence, and enhance safety and convenience. It is worth promoting and applying in the industry.
[0079] 2. Reduce costs: Utilize the original side marker lights that come with the vehicle chassis as multi-functional indicator lights, avoiding the cost of installing additional lights.
[0080] 3. Enhanced intelligence level: Through the intelligent control of VCU, multiple functions such as driving instructions, charging status display and intelligent charging instructions are realized, which enhances the intelligence level of the vehicle.
[0081] 4. Enhanced safety and convenience: Clear indicator light signals help drivers and maintenance personnel understand the vehicle status in a timely manner, improving the safety and convenience of operation.
