Description

Technical Field

[0001] This utility model mainly relates to the technical field of electric control systems for electric loaders, specifically an electric loader locking control system. Background Technology

[0002] Electric loaders are being used more and more frequently. As electric loaders become more feature-rich, the application of features such as one-button start modules and large-screen instruments makes it possible to prevent theft of the entire machine by entering a password.

[0003] Traditional loaders are powered on by turning the ACC and ON positions with a key, and the entire vehicle immediately enters working mode. If the machine is stolen, there are no preventative measures, which poses a high risk.

[0004] Traditional loaders lack a touch screen; the instrument panel only displays information and cannot be used for password input. Furthermore, the machine cannot be powered on via software using a password, making it easy to steal once the key is inserted, posing a significant risk.

[0005] Therefore, it is necessary to add a password input function to the instrument module to enable the VCU to monitor passwords and thus prevent the theft of the entire vehicle. Utility Model Content

[0006] Therefore, the purpose of this utility model is to provide an electric loader locking control system to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an electric loader locking control system, including a one-button start module, wherein the one-button start module is electrically connected to an instrument operation module, a vehicle control module, a battery system module, and a vehicle electronic control module; the vehicle control module is connected to the instrument operation module, the battery system module, and the vehicle electronic control module via a CAN bus.

[0008] According to one embodiment of the present invention, the battery system module includes a BMS unit and a main and negative relay.

[0009] According to one embodiment of the present invention, the vehicle electronic control module includes a main positive relay, a precharge relay, a precharge resistor, a T-MCU, a P-MCU, a DC-DC converter, and an ACM.

[0010] According to one embodiment of the present invention, the precharge relay is connected in series with the precharge resistor, and the precharge relay and the precharge resistor are connected in parallel with the main positive relay.

[0011] According to one embodiment of the present invention, both the main positive relay and the main negative relay are electrically connected to the T-MCU, P-MCU, DCDC, and ACM.

[0012] According to one embodiment of the present invention, both the main positive relay and the main negative relay are electrically connected.

[0013] According to one embodiment of the present invention, the T-MCU is used to control the T-Motor, the P-MCU is used to control the P-Motor, the DC-DC converter is used to control the battery, and the ACM is used to control the air pump motor.

[0014] In summary, the present invention has the following main advantages:

[0015] The electric loader locking control system of this utility model effectively prevents unauthorized personnel from starting the loader through a password verification mechanism, avoiding the risk of potential misoperation and theft.

[0016] The vehicle control module continuously monitors the instrument panel password flag five times via the CAN bus. Only when the password monitoring flag is 1 for five consecutive times is the password considered correct and the next operation proceeded. This multi-monitoring mechanism effectively avoids erroneous operations caused by accidental factors, further improving the system's reliability.

[0017] When the password monitoring flag is 0, the vehicle control module does not enable the T-MCU and P-MCU, so the drive motor and the work motor cannot work. At the same time, the air conditioner is not enabled, but the ACM air pump control module is enabled, so that the vehicle air brake system works normally. It also enables the DC-DC converter, which steps down the battery voltage to a low voltage working voltage to power the vehicle's low voltage equipment.

[0018] This avoids the situation where the vehicle's low-voltage electrical equipment continues to operate without a password being entered for an extended period, leading to a depletion of the low-voltage battery. This extends the lifespan of the low-voltage battery and reduces problems such as difficulty in starting equipment due to a depleted battery. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Example

[0026] Please refer to the appendix carefully. Figure 1 As shown, in a preferred embodiment of this utility model, an electric loader locking control system includes a one-button start module 1, which is electrically connected to an instrument operation module 2, a vehicle control module 3, a battery system module 4, and a vehicle electronic control module 5; the vehicle control module 3 is connected to the instrument operation module 2, the battery system module 4, and the vehicle electronic control module 5 via a CAN bus.

[0027] It should be noted that in this embodiment, after the one-button start operation is performed through the one-button start module 1, the instrument operation module 2, the vehicle control module 3, the battery system module 4, and the vehicle electronic control module 5 are all awakened. After the self-test is successful: the instrument operation module 2 enters the password input interface and waits for the password to be entered: if no password is entered or the password is entered incorrectly, the password monitoring flag is at position 0; if the password is entered correctly, the password monitoring flag is at position 1. The above password monitoring flag values ​​are sent to the vehicle control module 3 through the CAN line.

[0028] Please refer to the appendix carefully. Figure 1-3 As shown, in another preferred embodiment of this utility model, the battery system module 4 includes a BMS unit and a main and negative relay, and the vehicle electronic control module 5 includes a main positive relay, a precharge relay, a precharge resistor, a T-MCU, a P-MCU, a DC-DC converter, and an ACM. The precharge relay is connected in series with the precharge resistor, and the precharge relay and the precharge resistor are connected in parallel with the main positive relay. The main positive relay and the main negative relay are both electrically connected to the T-MCU, P-MCU, DC-DC converter, and ACM. The main positive relay and the main negative relay are both electrically connected. The T-MCU is used to control the T-Motor, the P-MCU is used to control the P-Motor, the DC-DC converter is used to control the battery, and the ACM is used to control the air pump motor.

[0029] It should be noted that in this embodiment, the vehicle control module 3 requests the battery system module 4 to power on, and after completing the control of the main and negative relays in the battery system module 4, it feeds back the power-on completion status.

[0030] The vehicle control module 3 requests the vehicle electronic control module 5 to complete the control of the main positive precharge relay and the main positive relay, and to provide feedback on the power-on completion status. The vehicle control module 3 monitors the status of the instrument password flag bit 5 times through the CAN line and finds it to be 1. At this time, it enables the T-MCU (traction motor control unit) and P-MCU (power motor control unit) through the CAN line, and the travel motor and the work motor start working.

[0031] The vehicle control module 3 monitors the instrument password flag status via the CAN bus. When the status is 0, the T-MCU and P-MCU are not enabled, and neither the drive motor nor the work motor can operate. The air conditioner is also disabled and cannot operate. The ACM air pump control module is enabled, allowing the vehicle's air brake system to operate normally. The DC-DC converter is enabled, and it steps down the battery voltage to a low-voltage operating voltage to power the vehicle's low-voltage equipment. This prevents the low-voltage equipment from continuously operating without a password input, which could lead to battery depletion.

[0032] Furthermore, the password monitoring flag is sent to the vehicle control module 3 via the CAN bus, allowing the vehicle control module 3 to determine whether to proceed with the next operation. Continuous monitoring of the flag (e.g., all five times being "1") can be used to prevent accidental operation.

[0033] Furthermore, the CAN bus has advantages such as strong real-time performance, strong anti-electromagnetic interference capability, and long transmission distance, making it suitable for communication within vehicles.

[0034] Furthermore, the BMS unit is the battery management system, the T-Motor is the traction motor, and the P-Motor is the drive motor.

[0035] Based on the above embodiments, a control method for an electric loader locking control system will also be provided, including the following steps:

[0036] Step 1: One-button start; Perform a one-button start operation through the one-button start module 1 to wake up the instrument operation module 2, vehicle control module 3, battery system module 4, and vehicle electronic control module 5;

[0037] Step 2: Password verification; Instrument operation module 2 enters the password input interface, waits for the password to be entered, the password monitoring flag determines the password and sends it to the vehicle control module 3 via the CAN bus;

[0038] Step 3: Main and negative relay control; Based on the determination result of the password monitoring flag, the vehicle control module 3 requests the battery system module 4 to power on, and after completing the main and negative relay control in the battery system module 4, it feeds back the power-on completion status.

[0039] Step 4: Main positive relay control; Based on the determination result of the password monitoring flag, the vehicle control module 3 requests the vehicle electronic control module 5 to complete the control of the main positive pre-charge relay and the main positive relay, and feed back the power-on completion status;

[0040] Step 5: Electronic control adjustment; The vehicle control module 3 enables or disables the T-MCU, P-MCU, DC-DC, ACM, and air conditioning based on the determination result of the password monitoring flag bit.

[0041] When the password is entered correctly, the password monitoring flag is set to 1. When the password is entered incorrectly or no password is entered, the password monitoring flag is set to 0. The vehicle control module 3 continuously monitors the password monitoring flag status sent by the instrument operation module 2 via the CAN bus. When the password monitoring flag is continuously monitored to be 1, the T-MCU and P-MCU are enabled via the CAN bus. When the password monitoring flag is monitored to be 0, the T-MCU and P-MCU are not enabled, the air conditioning is not enabled, and the ACM and DC-DC converter are enabled.

[0042] The working principle of this utility model is as follows:

[0043] After a one-button start operation is performed via the one-button start module 1, the instrument operation module 2, vehicle control module 3, battery system module 4, and vehicle electronic control module 5 are all awakened. After a self-test without any problems, the instrument operation module 2 enters the password input interface and waits for the password to be entered. If no password is entered or the password is entered incorrectly, the password monitoring flag is set to 0. If the password is entered correctly, the password monitoring flag is set to 1. The above password monitoring flag values ​​are sent to the vehicle control module 3 via the CAN bus.

[0044] The vehicle control module 3 requests power to the battery system module 4, and after completing the control of the main and negative relays in the battery system module 4, it reports back that the power-on is complete.

[0045] The vehicle control module 3 requests the vehicle electronic control module 5 to complete the control of the main positive precharge relay and the main positive relay, and to provide feedback on the power-on completion status. The vehicle control module 3 monitors the status of the instrument password flag bit 5 times through the CAN line and finds it to be 1. At this time, it enables the T-MCU (traction motor control unit) and P-MCU (power motor control unit) through the CAN line, and the travel motor and the work motor start working.

[0046] The vehicle control module 3 monitors the instrument password flag status via the CAN bus. When the status is 0, the T-MCU and P-MCU are not enabled, and neither the drive motor nor the work motor can operate. The air conditioner is also disabled and cannot operate. The ACM air pump control module is enabled, allowing the vehicle's air brake system to operate normally. The DC-DC converter is enabled, and it steps down the battery voltage to a low-voltage operating voltage to power the vehicle's low-voltage equipment. This prevents the low-voltage equipment from continuously operating and causing the low-voltage battery to deplete if the password is not entered for an extended period of time.

[0047] The password monitoring flag is sent to the vehicle control module 3 via the CAN bus, allowing the vehicle control module 3 to determine whether to proceed with the next operation. Continuous monitoring of the flag (e.g., 5 consecutive "1"s) can prevent accidental operation.

[0048] The CAN bus has advantages such as strong real-time performance, strong resistance to electromagnetic interference, and long transmission distance, making it suitable for communication within vehicles.

[0049] The BMS unit is the battery management system, the T-Motor is the traction motor, and the P-Motor is the drive motor.
