[0027] Embodiment 1

[0028] Figure 1This is a flow chart of a vehicle electronic parking control method provided in the first embodiment of the present invention. This embodiment is applicable to wheeled vehicles that can carry work tools. The method can be executed by a vehicle electronic parking control device. The vehicle electronic parking control device can be implemented in the form of hardware and / or software. The vehicle electronic parking control device can be configured in a vehicle controller or an independent electronic device. Figure 1 As shown, the vehicle electronic parking control method of the present invention specifically includes:

[0029] S1: Acquire the vehicle's operating mode and vehicle driving data.

[0030] The operation mode is the operation mode of the vehicle with or without the operation machine. The operation modes of the present invention include but are not limited to: field operation mode and road transport mode. Typically, the operation content of the field operation mode includes but is not limited to: sowing, harvesting or plowing. In the road transport mode, the vehicle does not perform any operation content.

[0031] The vehicle driving data is data associated with the vehicle braking state and the driver's driving intention. Optionally, the vehicle driving data includes, but is not limited to: the driver's seat leaving state, slope detection data, vehicle speed detection data, brake detection data, gear detection data, parking instructions and driving instructions. The slope detection data of the present invention includes, but is not limited to, a flat ground mode and a ramp mode. In the flat ground mode, the inclination angle of the vehicle body is equal to 0; in the ramp mode, the inclination angle of the vehicle body is greater than 0.

[0032] Specifically, the vehicle's operating mode may come from physical button signals (such as operating mode button signals), human-computer interaction module signals (such as operating mode configuration signals provided by the touch screen), CAN bus signals (such as CAN bus signals provided by the vehicle controller), etc.; the driver's seat departure status may come from seat pressure sensors, camera sensors, CAN bus signals, etc.; slope detection data may come from inclination sensors, inertial navigation sensors, CAN bus signals, etc.; vehicle speed detection data may come from speed sensors, CAN bus signals, etc.; braking detection data may come from brake pressure sensors, brake travel switches, CAN bus signals, etc.; parking instructions may come from physical button signals (such as parking button signals), human-computer interaction module signals (such as parking configuration signals provided by the touch screen), CAN bus signals, etc.

[0033] S2: Determine the parking control threshold according to the operation mode and slope detection data.

[0034] The parking control threshold may be a critical value in a specific parking control strategy for deciding whether to trigger automatic parking. In this embodiment, the parking control strategy includes a parking combination control strategy and a parking release control strategy. Typically, the parking combination control strategy includes but is not limited to: parking command triggers automatic parking, driver leaving the seat triggers automatic parking, and vehicle parking triggers automatic parking. The parking release control strategy includes but is not limited to: parking command releases parking and driving command releases parking.

[0035] Optionally, the parking control threshold includes a time threshold for leaving the seat and a time threshold for parking. The time threshold for leaving the seat indicates the minimum waiting time for the driver to leave the seat and trigger the automatic parking; the time threshold for parking indicates the minimum waiting time for the vehicle to park and trigger the automatic parking.

[0036] In some embodiments, the parking control threshold is determined according to the operation mode and the slope detection data, including: determining the leave-seat time threshold according to the operation mode; and / or determining the parking time threshold according to the operation mode and the slope detection data. Specifically, the leave-seat time threshold and the parking time threshold corresponding to different operation modes and slope detection data can be established by calibration or user customization. It should be noted that, in the same operation mode (such as the field operation mode), the leave-seat time threshold and the parking time threshold are positively correlated with the road friction, that is, in the same operation mode (such as the field operation mode), the smaller the road friction (for example, an icy and snowy road), the smaller the corresponding leave-seat time threshold, and the smaller the corresponding parking time threshold.

[0037] S3: Parking control is performed on the vehicle according to the vehicle driving data and the parking control threshold.

[0038] In this embodiment, parking control is performed on the vehicle based on vehicle driving data and parking control thresholds, including: determining whether to activate any parking control strategy based on vehicle driving data and parking control thresholds (such as an absence time threshold and a parking time threshold), and controlling parking engagement or parking release according to the corresponding parking control strategy. Specifically, when the vehicle driving data and the parking control threshold meet the conditions for activating the "parking command triggering automatic parking" control strategy, the parking brake is controlled to engage and the automatic parking brake is applied to the vehicle; when the vehicle driving data and the parking control threshold meet the conditions for activating the "driver leaving the seat triggering automatic parking" control strategy, the parking brake is controlled to engage and the automatic parking brake is applied to the vehicle; when the vehicle driving data and the parking control threshold meet the conditions for activating the "vehicle parking triggering automatic parking" control strategy, the parking brake is controlled to engage and the automatic parking brake is applied to the vehicle; when the "parking command release parking" control strategy is activated based on the parking command, the parking brake is controlled to be released and the parking brake on the vehicle is released; when the "driving command release parking" control strategy is activated based on the driving command, the parking brake is controlled to be released and the parking brake on the vehicle is released.

[0039] Therefore, the technical solution of the present invention solves the problem that the existing parking control strategy is easily affected by differences in operating conditions, resulting in false triggering of parking and poor reliability of parking brakes. By identifying the vehicle operating mode, automatically adjusting the parking control threshold in combination with the operating mode and slope detection data, and automatically switching the vehicle parking state in combination with the vehicle driving data and the adjusted threshold, the technical solution of the present invention solves the problem that the existing parking control strategy is easily affected by differences in operating conditions, resulting in false triggering of parking and poor reliability of parking brakes. By identifying the vehicle operating mode, automatically adjusting the parking control threshold in combination with the operating mode and slope detection data, and automatically switching the vehicle parking state in combination with the vehicle driving data and the adjusted threshold, the adaptability of the parking brake system to different operating conditions is improved, the reliability of parking brakes is improved, and the safety and convenience of vehicle driving are improved.

[0040] Figure 2 A flowchart of another vehicle electronic parking control method provided in Embodiment 1 of the present invention. Figure 1 On the basis of the illustrated embodiment, a specific implementation method of a parking strategy under different operating conditions is exemplarily shown.

[0041] See also Figure 2 As shown, in the above step S3, parking control is performed on the vehicle according to the vehicle driving data and the parking control threshold, including:

[0042] S301: When the vehicle is in a parking release state and receives a parking instruction, a first parking engagement instruction is triggered.

[0043] In this embodiment, the first parking engagement instruction may be set to be triggered by a rising edge of the parking instruction.

[0044] Specifically, the initial state of the first parking engagement instruction may be set to FALSE; if the current vehicle is in the "parking release" state and a rising edge of the parking instruction is received, the first parking engagement instruction is set to TRUE to trigger the first parking engagement instruction.

[0045] S302: Determine a second parking combination instruction according to the driver's seat leaving state and a seat leaving duration threshold.

[0046] In this embodiment, the seat leaving time threshold may be defined as t1. The seat leaving time threshold t1 is not a fixed value and may be adaptively adjusted based on the vehicle's operating mode.

[0047] Specifically, the initial state of the second parking engagement instruction can be set to FALSE. When the driver's seat leaving state changes from "not leaving the seat state" to "leaving the seat state", and when the duration of the "leaving the seat state" exceeds the seat leaving duration threshold t1, the second parking engagement instruction is set to TRUE to trigger the second parking engagement instruction.

[0048] S303: Determine a third parking combination instruction according to the slope detection data, the vehicle speed detection data, the braking detection data and the parking time threshold.

[0049] In this embodiment, the parking time threshold may be defined as t2. The parking time threshold t2 is not a fixed value, and it may be adaptively adjusted based on the vehicle's operating mode and slope detection data.

[0050] In some embodiments, the driver's driving intention can be identified based on the vehicle speed detection data and the brake detection data to determine whether the vehicle needs to park. In other embodiments, the driver's driving intention can be identified based on the vehicle speed detection data, the brake detection data, and the gear detection data to determine whether the vehicle needs to park.

[0051] Specifically, the initial state of the third parking engagement instruction can be set to FALSE. When the vehicle speed detection data is less than the vehicle speed threshold v1, and the brake detection data corresponds to the brake being pressed, and the above conditions are maintained to exceed the parking time threshold t2, the third parking engagement instruction is set to TRUE to trigger the third parking engagement instruction. Preferably, the vehicle speed threshold v1 is the vehicle speed value when the vehicle is almost parked, for example, 0.1 km / h.

[0052] S304: Performing parking control on the vehicle according to any one of the first parking combination instruction, the second parking combination instruction, or the third parking combination instruction.

[0053] In some embodiments, the parking combination control of the vehicle can be performed based on the order of command triggering of the first parking combination command, the second parking combination command or the third parking combination command. Specifically, if the parking command is responded to first, that is, the first parking combination command is triggered, the parking brake is controlled to be engaged based on the first parking combination command, and the automatic parking brake is applied to the vehicle; if the automatic parking control for leaving the seat is responded to first, that is, the second parking combination command is triggered, the parking brake is controlled to be engaged based on the second parking combination command, and the automatic parking brake is applied to the vehicle; if the automatic parking control for parking is responded to first, that is, the third parking combination command is triggered, the parking brake is controlled to be engaged based on the third parking combination command, and the automatic parking brake is applied to the vehicle.

[0054] In other embodiments, before performing parking engagement control on the vehicle, it also includes: obtaining an upper parking speed threshold that allows parking to be executed, and when any one of the first parking engagement instruction, the second parking engagement instruction or the third parking engagement instruction is triggered, and the vehicle speed detection data is less than the upper parking speed threshold, performing parking engagement control on the vehicle to avoid damaging the parking brake by performing parking braking at high speed, thereby improving the reliability of parking braking.

[0055] See also Figure 2As shown, in the above step S3, parking control is performed on the vehicle according to the vehicle driving data and the parking control threshold, and further includes:

[0056] S305: When the vehicle is in the parking engagement state and receives a parking instruction, triggering a first parking release instruction.

[0057] In this embodiment, the first parking release instruction may be set to be triggered by a rising edge of the parking instruction.

[0058] Specifically, the initial state of the first parking release command may be set to FALSE; if the current vehicle is in the "parking engagement" state and a rising edge of the parking command is received, the first parking release command is set to TRUE, and at this time, the first parking release command is triggered.

[0059] S306: When receiving the driving instruction, triggering a second parking release instruction.

[0060] In this embodiment, the second parking release instruction may be triggered by a rising edge of the driving instruction.

[0061] Specifically, the initial state of the second parking release command can be set to FALSE; after receiving the rising edge of the driving command, the second parking release command is set to TRUE, at which time, the second parking release command is triggered. In this embodiment, the driving command can be a signal corresponding to the driver's driving intention determined by the brake pedal, the shift command signal, the accelerator pedal signal, the cruise speed handle signal, etc.

[0062] S307: Performing parking release control on the vehicle according to the first parking release command or the second parking release command.

[0063] In some embodiments, the parking release control of the vehicle may be performed based on the order of triggering the first parking release command or the second parking release command. Specifically, if the parking command is first responded to when the vehicle is parked, that is, the first parking release command is triggered, then the parking brake is controlled to be released based on the first parking release command to release the parking brake of the vehicle; if the driving command (such as releasing the brake pedal or stepping on the accelerator pedal) is first responded to when the vehicle is parked, that is, the second parking release command is triggered, then the parking brake is controlled to be released based on the second parking release command to release the parking brake of the vehicle.

[0064] Therefore, the technical solution of the present invention automatically adjusts the parking control threshold and the parking control strategy in combination with the operating conditions of the vehicle, thereby improving the adaptability of the parking brake system to different operating conditions and improving the reliability of the parking brake.

[0065] In some embodiments, the first seat-leaving time threshold in the field operation mode is greater than the second seat-leaving time threshold in the road transportation mode. Exemplarily, the first seat-leaving time threshold can be set to 10 seconds, and the second seat-leaving time threshold can be set to 3 seconds.

[0066] In some embodiments, when the operation mode is the field operation mode and the slope detection data is the flat mode, the vehicle has a first parking time threshold t21; when the operation mode is the field operation mode and the slope detection data is the ramp mode, the vehicle has a second parking time threshold t22; when the operation mode is the road transport mode and the slope detection data is the flat mode, the vehicle has a third parking time threshold t23; when the operation mode is the road transport mode and the slope detection data is the ramp mode, the vehicle has a fourth parking time threshold t24; the first parking time threshold t21 is greater than the third parking time threshold t23, and the third parking time threshold t23 is greater than or equal to the second parking time threshold t22, and the second parking time threshold t22 is greater than the fourth parking time threshold t24. Exemplarily, the first parking time threshold t21 can be set to 15 seconds; the second parking time threshold t22 can be set to 5 seconds; the third parking time threshold t23 can be set to 10 seconds; and the fourth parking time threshold t24 can be set to 3 seconds.

[0067] Figure 3 A flowchart of another vehicle electronic parking control method provided in the first embodiment of the present invention is shown in FIG. Figure 1 Based on the embodiment shown, a specific implementation method for arbitrating and managing parking instructions is exemplarily shown. Figure 3 As shown, the vehicle electronic parking control method of the present application includes:

[0068] S1: Acquire the vehicle's operating mode and vehicle driving data.

[0069] S2: Determine the parking control threshold according to the operation mode and slope detection data.

[0070] S3: Parking control is performed on the vehicle according to the vehicle driving data and the parking control threshold.

[0071] S4: Customize the parking strategy priorities for different operation modes.

[0072] Among them, the parking strategy priority is used to limit the response order of different parking commands in a specific operating mode.

[0073] S5: Arbitrating the parking engagement command and the parking release command according to the parking strategy priority.

[0074] Specifically, the human-computer interaction module can be used to display a parking strategy priority customization window, and the parking strategy priorities in different operation modes can be adjusted accordingly in response to the user's operation instructions. For example, in the field operation mode, the priority of the automatic parking instruction when leaving the seat can be set higher than the priority of the automatic parking instruction when parking, that is, the automatic parking control strategy when leaving the seat is given priority; in the road display mode, the priority of the automatic parking instruction when parking can be set higher than the priority of the automatic parking instruction when leaving the seat, that is, the automatic parking control strategy when parking is given priority. By customizing and expanding the automatic parking control strategy and its priority, the adaptability of the automatic parking control strategy to different operation conditions is optimized, and the user experience is improved.

[0075] In some embodiments, the parking strategy priority can be set as follows: the priority of the first parking engagement instruction is higher than the priority of the first parking release instruction; the priority of the first parking release instruction is higher than the priority of the second parking engagement instruction; the priority of the second parking engagement instruction is higher than the priority of the third parking engagement instruction; the priority of the third parking engagement instruction is higher than the priority of the second parking release instruction.

[0076] Figure 4 A schematic diagram of the control logic of a parking command arbitration method provided by an embodiment of the present invention.

[0077] See also Figure 4 , different parking commands are arranged in descending order of priority as follows: parking button command > automatic parking command when leaving the seat > automatic parking command when parking > parking release command when driving, that is, each parking command is analyzed in the following order: first parking combination command → first parking release command → second parking combination command → third parking combination command > second parking release command, and the parking state is switched based on the parking command. By configuring the parking command arbitration strategy, redundant control between multiple parking commands is realized, and the reliability of automatic parking brake is improved.
