[0001] Cross-references to related applications
[0002] This application claims priority to Chinese Patent Application No. 202510141505.8, filed on February 8, 2025, the entire contents of which are incorporated herein by reference for all purposes. Technical Field
[0003] This application relates to the field of mining truck control technology, and in particular to a parking control method, device, system, electronic equipment and vehicle. Background Technology
[0004] In recent years, with the gradual advancement of green mining, more and more mining areas are using new energy mining trucks. Compared with traditional pure oil mining trucks, new energy mining trucks need to be connected to charging stations for charging. This requires the vehicle to be parked while charging; otherwise, if it rolls away, it will damage the charging equipment and cause a safety accident. At the same time, traditional mining trucks also need to ensure that the parking brake is applied when the vehicle is stopped and the power is off to prevent accidents such as rolling away or collisions. However, the driver, as an uncontrollable factor, cannot guarantee that the parking brake will be applied correctly every time. Therefore, ensuring that the mining truck is in a parked state during the power-off and power-on initialization phases is particularly important.
[0005] The inventors recognized that traditional parking strategies are typically purely mechanical, requiring the driver to manually control the parking switch. As the driver is an uncontrollable factor, there's a possibility they might forget to activate the parking switch, resulting in a low level of automation. Furthermore, existing technology doesn't adequately address serious malfunctions in unmanned systems. When the unmanned system cannot effectively control the vehicle, there's a risk of ineffective braking. Since there's no driver on board, the parking signal cannot be manually activated, potentially creating safety hazards. Application content

It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0033] In recent years, with the gradual advancement of green mining, more and more mining areas are using new energy mining trucks. Compared with traditional pure oil mining trucks, new energy mining trucks need to be connected to charging stations for charging. This requires the vehicle to be parked while charging; otherwise, if it rolls away, it will damage the charging equipment and cause a safety accident. At the same time, traditional mining trucks also need to ensure that the parking brake is applied when the vehicle is stopped and the power is off to prevent accidents such as rolling away or collisions. However, the driver, as an uncontrollable factor, cannot guarantee that the parking brake will be applied correctly every time. Therefore, ensuring that the mining truck is in a parked state during the power-off and power-on initialization phases is particularly important.
[0034] Traditional parking strategies are typically purely mechanical, requiring the driver to manually control the parking switch. As the driver is an uncontrollable factor, there's a possibility they might forget to activate the parking brake, resulting in a low level of automation. Furthermore, current technology doesn't adequately address serious malfunctions in unmanned systems. When the unmanned system fails to effectively control the vehicle, there's a risk of ineffective braking. Since there's no driver on board, the parking signal cannot be manually activated, potentially creating safety hazards.
[0035] To address the aforementioned technical problems, this application proposes an intelligent safety parking control system for mining trucks. This system includes a data acquisition system and a vehicle control unit (VCU). The data acquisition system collects vehicle monitoring data in real time, and the VCU autonomously determines whether the vehicle should enter a static safety monitoring mode or a dynamic active intervention mode based on this data. In safety monitoring mode, the VCU monitors in real time whether the driver operates the parking rocker switch or whether the parking command from the unmanned system changes, enabling or disabling the parking system to effectively prevent rollover caused by the driver forgetting to park. In active intervention mode, the VCU monitors the vehicle's operating status in real time. When it detects insufficient emergency braking force, an abnormal electric braking system, a malfunction in the Electronic Brake System (EBS), or a malfunction in the unmanned system with insufficient braking force, the VCU automatically enables the parking system, providing additional braking force to the vehicle and significantly improving overall vehicle safety. In addition, this patent applies for a detection method for determining the enabling and disabling conditions of the parking brake under different modes, based on changes in the parking rocker switch or the parking request command of the unmanned system, to ensure that the vehicle parking system is always safe and controllable.
[0036] The technical solution of this application will be described in detail below:
[0037] Figure 1 is a flowchart of a parking control method provided in an embodiment of this application. This method can be executed by a parking control method, but is not limited thereto. As shown in Figure 1, the method may include the following steps:
[0038] Step 110: Obtain vehicle monitoring data for the target vehicle.
[0039] The target vehicle is the vehicle to be parked; the vehicle monitoring data includes at least: power monitoring signals, electronic control unit communication status, sensor monitoring signals, and braking system component feedback signals.
[0040] In specific application scenarios, vehicle monitoring data of the target vehicle can be obtained through data acquisition systems, such as on-board diagnostic systems, direct sensor acquisition, vehicle network communication, and external testing equipment.
[0041] As one possible approach, when acquiring vehicle monitoring data of a target vehicle through an on-board diagnostic system (OBD), a hardware connection can be used. Diagnostic equipment compatible with the OBD interface can be employed to establish a physical connection with the vehicle's Electronic Control Unit (ECU) via the OBD-II interface. Alternatively, software operation can be used. This software can communicate with the vehicle's ECU, sending commands to request various monitoring data. Power monitoring signals can be read to understand battery voltage, current, and other information; the communication status of the ECUs can be obtained to check whether each ECU is working properly and whether communication between them is smooth; and fault codes and data related to the braking system can also be read, indirectly reflecting feedback signals from braking system components.
[0042] As another possible implementation, when using sensors to directly collect vehicle monitoring data of the target vehicle, power system sensors (such as voltage sensors, current sensors, etc.) of the vehicle can be used to obtain power monitoring signals, and various sensors on the vehicle, such as temperature sensors, pressure sensors, speed sensors, etc., can be used to perceive various physical state information of the vehicle in real time.
[0043] As another possible implementation, when acquiring vehicle monitoring data of a target vehicle based on vehicle network communication, the vehicle's internal systems typically use a Controller Area Network (CAN) bus for data communication. Various ECUs, sensors, and actuators are connected to the CAN bus, and power monitoring signals, electronic control unit communication status, sensor monitoring signals, and braking system component feedback signals are all transmitted on the CAN bus. The required vehicle monitoring data can be obtained by listening to and collecting data on the bus according to the CAN protocol through node devices connected to the CAN bus, such as onboard gateways or dedicated data acquisition units.
[0044] As another possible approach, when acquiring vehicle monitoring data for the target vehicle using external testing equipment, specialized braking system testing equipment, such as brake pressure testers and brake pedal travel testers, can be used. These devices can be directly connected to the corresponding parts of the braking system to measure and monitor parameters such as brake system pressure and travel in real time, obtaining accurate feedback signals from braking system components.
[0045] Step 120: Analyze the vehicle operating status based on vehicle monitoring data. The vehicle operating status can be any one of the following: vehicle power-off state, vehicle power-on state, or abnormal braking system state.
[0046] The vehicle's power-off state refers to the state where the vehicle's main electrical and power systems are shut down or not in operation. In this state, the vehicle's key switch is in the off position, or the start / stop button is pressed to cut off the power. In this state, the power system: except for reserving a small amount of power for some basic storage functions and anti-theft systems, the connection between the vehicle's main power source (such as the battery) and most electrical equipment is disconnected to reduce energy consumption. The power system: the engine stops running (for gasoline vehicles), the electric motor stops outputting power (for new energy vehicles), and the vehicle loses its ability to drive itself. Electrical equipment: most non-essential electrical equipment such as the instrument panel, multimedia system, and air conditioning system stops working; only some circuits with memory or standby functions maintain a weak current supply. For example, the vehicle's electronic control unit (ECU) may be in a dormant state but is still monitoring certain signals so that it can quickly resume operation when the vehicle is powered on again. The vehicle's power-on state, the opposite of the power-off state, refers to the state where the vehicle's electrical and power systems are activated and ready to work or are working. When the vehicle's key is turned to the start position or the start / stop button is pressed, the vehicle enters the power-on state. In this state, the power system (main power source, battery or accumulator) supplies power to the vehicle's various electrical systems and electronic control units, providing electrical support for vehicle operation. The power management system starts working, monitoring and adjusting parameters such as output voltage and current to ensure that each system can stably obtain the required electrical energy. The powertrain system starts and runs (in gasoline vehicles), or the electric motor is ready to output power (in new energy vehicles), providing power for vehicle movement. The powertrain control unit performs a series of self-checks and initialization operations to ensure that the engine or motor and related transmission components are in normal working condition. The electrical equipment: the instrument panel lights up, displaying various vehicle status information such as vehicle speed, engine speed, water temperature, and battery level; various electrical devices such as the multimedia system and air conditioning system also start working, and the driver can operate and set these devices as needed. The vehicle's electronic control unit communicates with various sensors and actuators, monitoring the vehicle's operating status in real time and controlling the operation of each system based on the driver's operation and the actual situation of the vehicle. An abnormal braking system condition refers to a malfunction or inability to function properly in the vehicle's braking system. The braking system is a crucial system for ensuring safe vehicle operation. The braking system can be considered to be in an abnormal state when the following conditions occur:
[0047] Decreased braking performance: The braking distance is significantly increased, meaning that after the driver presses the brake pedal, the vehicle requires a longer distance to stop than normal. This may be caused by insufficient braking pressure or poor transmission of braking force due to severely worn brake pads, brake fluid leakage, or blockage in the brake lines.
[0048] Braking deviation: During braking, the vehicle cannot decelerate and stop in a straight line, but instead veers to one side. This is usually caused by uneven braking force on the left and right sides, which may be due to uneven wear of the brake pads on one side, a faulty brake caliper, inconsistent tire pressure, or other reasons.
[0049] Brake noise: When the brake pedal is pressed, the braking system emits abnormal noises, such as screeching, friction, or impact sounds. This may be caused by foreign objects between the brake pads and the brake disc, excessive wear of the brake pads causing direct contact between the metal lining and the brake disc, or a loose brake caliper.
[0050] Abnormal brake pedal feel: Abnormal brake pedal feel, such as excessive pedal travel, soft pedal, or hard pedal. Excessive pedal travel may be due to air in the braking system or excessive brake pad clearance; a soft pedal may be due to brake fluid leakage or air in the brake lines; a hard pedal may be due to a malfunction in the brake booster system, requiring the driver to apply more force to press the brake pedal.
[0051] The malfunction indicator light illuminates: The brake system malfunction indicator light on the vehicle's dashboard illuminates, alerting the driver to a problem with the brake system. This could be due to a faulty component in the brake system, such as a faulty wheel speed sensor, a faulty electronic control unit (ECU), or low brake fluid level. The ECU detects the fault and triggers the malfunction indicator light to remind the driver to have it checked and repaired promptly.
[0052] Step 130: Determine the parking control mode that matches the vehicle's operating status.
[0053] In this embodiment of the disclosure, corresponding parking control modes can be configured specifically for the vehicle's power-off state, vehicle power-on state, and abnormal braking system state, so as to comprehensively consider multiple aspects such as safety, convenience, comfort, and vehicle protection, and provide drivers with a better driving experience and vehicle protection effect.
[0054] Step 140: Based on the parking control mode, control the execution of parking operations on the target vehicle.
[0055] In summary, the technical solution in this application, after acquiring vehicle monitoring data of the target vehicle, analyzes the vehicle's operating status based on the monitoring data. The vehicle's operating status can be any one of the following: vehicle power-off state, vehicle power-on state, or abnormal braking system state. Then, a parking control mode matching the vehicle's operating status is determined. Finally, based on the parking control mode, the parking operation on the target vehicle is controlled and executed. The technical solution in this disclosure can achieve parking control of the vehicle under different vehicle operating states, ensuring intelligent parking while comprehensively considering safety, convenience, comfort, and vehicle protection, providing drivers with a better driving experience and vehicle protection.
[0056] Based on the detailed description of the parking control method provided in Figure 2 above, and as shown in Figure 3, which is a flowchart illustrating a parking control method according to an exemplary embodiment, the method includes:
[0057] Step 210: Obtain vehicle monitoring data for the target vehicle.
[0058] The vehicle monitoring data includes at least: power monitoring signals, electronic control unit communication status, sensor monitoring signals, and feedback signals from braking system components.
[0059] For the specific implementation process of the embodiments disclosed herein, please refer to the relevant description in step 110 of the embodiment, which will not be repeated here.
[0060] Step 220: Analyze the vehicle's operating status based on vehicle monitoring data.
[0061] For the specific implementation process of the embodiments disclosed herein, please refer to the relevant description in step 120 of the embodiments, which will not be repeated here.
[0062] Step 230a: When the vehicle status information is that the vehicle is powered off, determine the first parking control mode corresponding to the vehicle power-off state. The first parking control mode is used to automatically enable parking.
[0063] When the vehicle is powered off, the system determines a specific parking control mode suitable for that state based on preset logic and procedures; this is termed the first parking control mode. This process is completed by the vehicle control system based on the recognition and judgment of the vehicle's current state. Automatic parking typically refers to the system automatically applying braking force to keep the vehicle stationary and prevent it from sliding or moving when certain conditions are met (such as the vehicle being completely stopped or in the appropriate gear). This automatic parking function works when the vehicle is powered off, providing users with a more convenient and safer parking experience and avoiding the risk of the vehicle rolling due to forgetting to engage the handbrake.
[0064] Step 240a: Send a parking brake enable signal. The parking brake enable signal is used to indicate that automatic parking control will be performed on the target vehicle after power-off.
[0065] In this embodiment of the present disclosure, the vehicle control unit can send a parking brake enable signal to the vehicle system. The vehicle system will automatically activate the relevant mechanism based on the received parking brake enable signal, and apply appropriate braking force through the braking system to keep the vehicle stationary, prevent the vehicle from moving due to various factors (such as uneven road surface), and ensure the safety of the vehicle in the parking state.
[0066] In step 230b of the embodiment, which is parallel to step 230a of the embodiment, when the vehicle status information is that the vehicle is powered on, a second parking control mode corresponding to the vehicle power-on state is determined.
[0067] When the vehicle's status information indicates that it is powered on, meaning that the vehicle's electrical and power systems have been activated and are ready to run or are running, the vehicle control unit will determine a parking control mode suitable for this state based on preset rules. This is called the second parking control mode. This mode is specifically designed for various situations when the vehicle is powered on and differs from the parking control mode corresponding to the vehicle's powered-off state.
[0068] After the vehicle is powered on, the automatic parking mode will remain in operation to maintain the vehicle's parked state as long as the preset conditions for releasing the parking brake are not met. For example, if the vehicle is stopped at a red light and the driver has started the vehicle (power on), but the preset conditions for releasing the parking brake, such as pressing the accelerator pedal or fastening the seatbelt, have not yet been met, the second parking control mode will keep the vehicle parked to prevent accidental movement. Once the preset conditions for releasing the parking brake are met, the second parking control mode will cancel the automatic parking control and hand over control of the target vehicle to the driver or autonomous system. These preset conditions may include various factors, such as the driver pressing the accelerator pedal, indicating the driver's intention to move forward; or the automatic transmission vehicle shifting from parking (P) to another driving gear. When the vehicle control system detects that these conditions are met, the second parking control mode will issue a command to cancel the automatic parking control and hand over control of the vehicle to the driver or autonomous system, who will then decide whether to release the parking brake.
[0069] Accordingly, for embodiments of this disclosure, the steps may include: determining the vehicle operating mode of the target vehicle, the vehicle operating mode including manned mode and unmanned mode; generating preset release conditions corresponding to the vehicle operating mode; determining a second parking control mode corresponding to the vehicle's power-on state based on the preset release conditions, the second parking control mode being used to maintain the parking state of the target vehicle before determining that the target vehicle meets the preset release conditions, and to cancel automatic parking control and hand over the parking control of the target vehicle to the driver or unmanned system when determining that the target vehicle meets the preset release conditions.
[0070] Accordingly, when generating the preset release conditions corresponding to the vehicle operation mode, the implementation steps may include: generating a first preset release condition for manned mode, wherein the first preset release condition is that the target vehicle is not plugged into the charging gun and the parking rocker switch is enabled or the parking rocker switch is manually operated; generating a second preset release condition for unmanned mode, wherein the second preset release condition is that the unmanned parking request is enabled or the unmanned system parking request changes.
[0071] In step 240b of embodiment 240a, which is parallel to step 240a of embodiment 240, the parking operation on the target vehicle is controlled to be performed based on the second parking control mode.
[0072] In step 230c of embodiment 230a, when the vehicle status information is an abnormal state of the braking system, a third parking control mode corresponding to the abnormal state of the braking system is determined. The third parking control mode is used to perform parking control on the target vehicle when it is determined that the target vehicle meets the parking control conditions.
[0073] If the vehicle's monitoring system detects a problem with the braking system—whether due to brake fluid leakage, excessive brake pad wear, brake sensor malfunction, or other reasons—the vehicle is in an abnormal operating state, requiring special measures to ensure the safety of the vehicle and its occupants. Upon detecting a braking system anomaly, the vehicle control unit, based on pre-set programs and logic, selects a parking control mode specifically designed for this particular braking system malfunction—the third parking control mode. This mode is specifically designed for the braking system malfunction and differs from parking control modes under normal or fault conditions; it considers various risks and special requirements arising from the braking system malfunction. The vehicle control system continuously monitors various vehicle status parameters and environmental information to determine if parking control conditions are met. These conditions may include whether the vehicle speed has decreased to a safe parking level, whether there is sufficient space around the vehicle for parking, and whether the vehicle is approaching the designated parking location. Parking control is only triggered when all conditions are met. Once the target vehicle meets the parking control conditions, the third parking control mode is activated and begins operation. It uses other available systems in the vehicle (such as electronic parking brake system, emergency braking system, etc.) to park the vehicle, bringing it to a stop and keeping it stationary as safely and smoothly as possible, in order to avoid dangerous situations such as loss of control or collisions that may occur due to abnormal braking system.
[0074] In specific application scenarios, when determining that a target vehicle meets the parking control conditions, the implementation steps may include: real-time monitoring of the actual deceleration of the target vehicle; when it is determined that the actual deceleration is less than the expected deceleration under abnormal braking system conditions and the duration reaches a preset duration, the target vehicle is determined to meet the parking control conditions.
[0075] In step 240c of the embodiment, which is parallel to step 240a of the embodiment, the parking operation on the target vehicle is controlled to be performed based on the third parking control mode.
[0076] In summary, the technical solution in this application, after acquiring vehicle monitoring data of the target vehicle, analyzes the vehicle's operating status based on the monitoring data. The vehicle's operating status can be any one of the following: vehicle power-off state, vehicle power-on state, or abnormal braking system state. Then, a parking control mode matching the vehicle's operating status is determined. Finally, based on the parking control mode, the parking operation on the target vehicle is controlled and executed. The technical solution in this disclosure can achieve parking control of the vehicle under different vehicle operating states, ensuring intelligent parking while comprehensively considering safety, convenience, comfort, and vehicle protection, providing drivers with a better driving experience and vehicle protection.
[0077] Based on the detailed description of the parking control method provided in Figures 1 and 2 above, and as shown in Figure 3, which is a block diagram of a parking control device according to an exemplary embodiment, the device includes:
[0078] The acquisition module 31 can be used to acquire vehicle monitoring data of the target vehicle. The vehicle monitoring data includes at least: power monitoring signal, electronic control unit communication status, sensor monitoring signal and braking system component feedback signal.
[0079] Analysis module 32 can be used to analyze the vehicle operating status based on vehicle monitoring data. The vehicle operating status can be any one of the following: vehicle power-off state, vehicle power-on state, and abnormal braking system state.
[0080] The determination module 33 can be used to determine the parking control mode that matches the vehicle's operating status;
[0081] The control module 34 can be used to control the execution of parking operations on the target vehicle based on the parking control mode.
[0082] In some embodiments of this application, when the vehicle status information is a vehicle power-off state, the determining module 33 can be specifically used to determine a first parking control mode corresponding to the vehicle power-off state. The first parking control mode is used to automatically enable parking. Based on the parking control mode, the parking operation on the target vehicle is controlled to be executed, including: sending a parking brake enable signal, which is used to indicate that automatic parking control is performed on the target vehicle after power-off is completed.
[0083] In some embodiments of this application, when the vehicle status information indicates that the vehicle is powered on, the determining module 33 can be used to determine the vehicle operation mode of the target vehicle, which includes a manned mode and an unmanned mode; generate a preset release parking condition corresponding to the vehicle operation mode; and determine a second parking control mode corresponding to the vehicle's power-on state based on the preset release parking condition. The second parking control mode is used to maintain the parking state of the target vehicle before determining that the target vehicle meets the preset release parking condition, and to cancel the automatic parking control and hand over the parking control of the target vehicle to the driver or the unmanned system when determining that the target vehicle meets the preset release parking condition.
[0084] In some embodiments of this application, when generating preset release conditions corresponding to the vehicle operation mode, the determining module 33 can be specifically used to generate a first preset release condition in manned mode, wherein the first preset release condition is that the target vehicle is not plugged into the charging gun and the parking rocker switch is enabled or the parking rocker switch is manually operated; and to generate a second preset release condition in unmanned mode, wherein the second preset release condition is that the unmanned parking request is enabled or the unmanned system parking request changes.
[0085] In some embodiments of this application, when the vehicle status information is an abnormal braking system state, the determination module 33 can be used to determine the third parking control mode corresponding to the abnormal braking system state. The third parking control mode is used to perform parking control on the target vehicle when it is determined that the target vehicle meets the parking control conditions.
[0086] In some embodiments of this application, as shown in FIG4, the device further includes: a monitoring module 35;
[0087] Monitoring module 35 can be used to monitor the actual deceleration of the target vehicle in real time;
[0088] The determination module 33 can also be used to determine that the target vehicle meets the parking control conditions when the actual deceleration is less than the expected deceleration under abnormal braking system conditions and the duration reaches a preset duration.
