[0022] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.

[0023] ​The description such as "first", "second" and the like in the present application is only for the purpose of description and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features with "first", "second" can be explicitly or implicitly included at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or cannot be realized, it should be considered that the combination of technical solutions does not exist, nor within the protection scope required by the present application.

[0024] The embodiment of the present application provides a control method of a vehicle hood, the vehicle comprises a hood, an electric support rod, a hood lock motor, a support rod motor and a hood lock, the electric support rod is used for providing driving force for opening and closing of the hood, the hood lock is used for locking the opening and closing position range of the hood, the hood lock motor is used for driving the hood lock to switch between locking and unlocking, and the support rod motor is used for providing driving force for the electric support rod. Referring to Figure 1 As shown in the figure, the method comprises the following steps:

[0025] S101: in response to receiving an opening and closing instruction for the hood lock, determining a target locking position of the hood lock, and obtaining vehicle control information, the vehicle control information is used to represent the current running state of the vehicle.

[0026] It should be noted that the vehicle control information includes an opening and closing signal of the hood lock, a current locking position of the hood lock, a current hood position and a vehicle state.

[0027] It should be noted that the opening and closing signal includes a full lock opening signal and a half lock opening signal, the full lock opening signal is used to indicate that the hood lock is switched from the full lock position to the half lock position, and the half lock opening signal is used to indicate that the hood lock is switched from the half lock position to the full open position.

[0028] It should be noted that the hood lock in the full lock position represents that the hood is in the completely closed position. The hood lock in the half lock position represents that the hood is in the position of opening a certain angle, but at this time the hood is still limited by the hood lock and cannot be opened. The hood lock in the full open position represents that the hood lock no longer limits the opening of the hood, and at this time the hood can be freely opened.

[0029] S102: based on the vehicle control information, controlling the hood lock to switch from the current locking position to the target locking position, and the current locking position and the target locking position satisfy a pre-set switching sequence.

[0030] It should be noted that based on the vehicle control information, the hood lock is controlled to switch from the current locking position to the target locking position, which can realize the switching of the hood lock from full open to full lock, or from full lock to full open. Taking the switching of the hood lock from full lock to full open as an example, the hood lock can be switched from full lock to full open through 1 time, 2 times, 3 times or 4 times of opening.

[0031] Specifically, when the number of unlocking times is 2, the unlocking process of the hood lock comprises the following steps S1021-S1022:

[0032] S1021: If the switch lock signal is the full lock unlocking signal, and the current locking position is the full lock position, and the vehicle state is the first vehicle state, and the target locking position is the half lock position, then the hood lock is controlled to switch from the full lock position to the half lock position; wherein the switching from the full lock position to the half lock position is a pre-set switching sequence.

[0033] It should be noted that the first vehicle state refers to a vehicle state suitable for switching the hood lock from the full lock position to the half lock position, which can be that the vehicle speed is zero and the vehicle gear is P gear.

[0034] It can be understood that if the switch lock signal is the full lock unlocking signal and the current locking position is not the full lock position, then the process is ended, because the switch lock signal does not correspond to the current locking position.

[0035] It can be understood that if the vehicle state is not the first vehicle state, the user should be reminded to adjust the vehicle state to the first vehicle state, and then determine whether the vehicle state is adjusted to the first vehicle state after a period of time. If the vehicle state is adjusted to the first vehicle state, the hood lock is controlled to switch from the full lock position to the half lock position. If the vehicle state is not adjusted to the first vehicle state, the process is ended.

[0036] S1022: If the switch lock signal is the half lock unlocking signal, and the current locking position is the half lock position, and the vehicle state is the second vehicle state, and the target locking position is the full open position, then the hood lock is controlled to switch from the half lock position to the full open position, wherein the switching from the half lock position to the full open position is a pre-set switching sequence.

[0037] It should be noted that the second vehicle state refers to a vehicle state suitable for switching the hood lock from the half lock position to the full open position, which can be that the vehicle speed is zero and the vehicle gear is P gear.

[0038] It can be understood that if the switch lock signal is the half lock unlocking signal and the current locking position is not the half lock position, then the process is ended, because the switch lock signal does not correspond to the current locking position.

[0039] It can be understood that if the vehicle state is not the second vehicle state, the user should be reminded to adjust the vehicle state to the second vehicle state, and then determine whether the vehicle state is adjusted to the second vehicle state after a period of time. If the vehicle state is adjusted to the second vehicle state, the hood lock is controlled to switch from the half lock position to the full open position. If the vehicle state is not adjusted to the second vehicle state, the process is ended.

[0040] It should be noted that the steps S1021-S1022 achieve the hood lock from full lock to full open by 2 times of unlocking, and the hood lock from full lock to full open can also be achieved by multiple times of unlocking. Similarly, the hood lock from full open to full lock can be achieved by 1 time, 2 times, 3 times or 4 times of locking, so that the hood lock from full open to full lock.

[0041] It can be understood that in the process of controlling the hood lock to switch from the current locking position to the target locking position, the following steps 1-6 are also included:

[0042] Step 1: Determine whether the hood lock motor is in a running state.

[0043] Step 2: If the hood lock motor is not in a running state, start the hood lock motor.

[0044] Step 3: If the hood lock motor is in a running state, determine whether the hood lock is successfully switched from the current locking position to the target locking position.

[0045] Step 4: If the hood lock is not switched from the current locking position to the target locking position, monitor the first running current and the first running duration of the hood lock motor.

[0046] It can be understood that if the hood lock is switched from the current locking position to the target locking position, the hood lock motor is stopped and the process is ended.

[0047] Step 5: If the first running current exceeds the first current threshold or the first running duration exceeds the first duration threshold, it is determined that the hood lock is failed to switch from the current locking position to the target locking position, and the hood lock motor is restarted.

[0048] It should be noted that the first current threshold can be 200mA and the first duration threshold can be 2s. The reason why the first running current exceeds the first current threshold or the first running duration exceeds the first duration threshold can be that the hood lock encounters an obstacle, so that the running current and the running duration increase. Therefore, monitoring the first running current and the first running duration of the hood lock motor can protect the hood lock motor and prolong the service life.

[0049] Step 6: If the number of times that the hood lock fails to switch from the current locking position to the target locking position exceeds the first number threshold, the hood lock motor is turned off.

[0050] It should be noted that the first number threshold can be 2 times.

[0051] It can be understood that after the hood lock motor is turned off, the user can be prompted that the operation fails, the number of failures is cleared to zero, and the process is ended.

[0052] It should be noted that when the target locking position of the hood lock needs to meet certain conditions, the electric support rod is controlled to drive the hood to open and close to the target opening and closing position, so as to realize the hierarchical control of the hood lock and the electric support rod on the hood, and avoid the problem of hood opening due to false triggering. Therefore, after step S102, step S103 is further included.

[0053] S103: If the target locking position does not meet the target opening and closing position of the hood, re-trigger the switch lock instruction for the hood lock until the target locking position meets the target opening and closing position of the hood.

[0054] It should be noted that the target opening and closing position can be the maximum opening position, the closing position or the user-defined position of the hood.

[0055] It should be noted that the case that the target locking position does not meet the target opening and closing position of the hood includes the case that when the target locking position of the hood lock is the half-lock position, the electric support rod cannot be controlled to drive the hood to open and close to the maximum opening position. The target locking position meets the target opening and closing position of the hood, which includes the case that when the target locking position of the hood lock is the full-open position, the electric support rod can be controlled to drive the hood to open and close to the maximum opening position.

[0056] S104: If the target locking position meets the target opening and closing position of the hood, the electric support rod is controlled to drive the hood to open and close to the target opening and closing position based on the vehicle control information.

[0057] It can be understood that the method of controlling the electric support rod to drive the hood to open and close to the target opening and closing position based on the vehicle control information includes steps S1041-S1042:

[0058] S1041: If the current hood position is not at the target opening and closing position, and the vehicle state is the third vehicle state, the electric support rod is controlled to drive the hood to open to the target opening and closing position.

[0059] It should be noted that the third vehicle state refers to a vehicle state suitable for controlling the electric support rod to drive the hood to open to the target opening and closing position, which can be that the vehicle speed is zero and the vehicle gear is P gear.

[0060] Specifically, the target opening and closing position can be the maximum opening position of the hood. Therefore, when the target locking position of the hood lock is the full-open position, the current hood position is not at the maximum opening position, and the vehicle state is the third vehicle state, the electric support rod is controlled to drive the hood to open to the maximum opening position.

[0061] S1042: If the current hood position is not at the target opening and closing position, the electric support rod is controlled to drive the hood to close to the target opening and closing position.

[0062] Specifically, the target opening / closing position can be a closed position of the hood. Then, in the case that the target locking position of the hood lock is the full locking position, and the current hood position is not in the closed position, the electric support rod is controlled to drive the hood to close to the closed position.

[0063] It can be understood that there are various cases of controlling the electric support rod to drive the hood to open / close. In addition to the case of opening / closing to the target opening / closing position in steps S1041-S1042, the following steps 1-2 can also be included:

[0064] Step 1: Obtain an angle increasing signal set for the hood; if the current position of the hood is not in the maximum opening position of the hood, and the vehicle state is the fourth vehicle state, control the electric support rod to drive the hood to open to the hood position defined by the angle increasing signal.

[0065] It should be noted that the fourth vehicle state refers to a vehicle state suitable for controlling the electric support rod to drive the hood to open to the hood position defined by the angle increasing signal, which can be that the vehicle speed is zero and the vehicle gear is P gear.

[0066] It should be noted that the angle increasing signal can be a signal issued by the user when the hood stops due to an obstacle and the user wants the hood to continue to open.

[0067] Step 2: Obtain an angle decreasing signal set for the hood; if the current position of the hood is not in the minimum opening position of the hood, control the electric support rod to drive the hood to open to the hood position defined by the angle decreasing signal.

[0068] It should be noted that the angle decreasing signal can be a signal issued by the user when the hood stops due to an obstacle and the user wants the hood to continue to close.

[0069] It can be understood that in the process of controlling the electric support rod to drive the hood to open / close to the target opening / closing position, the following steps 1-6 are also included:

[0070] Step 1: Determine whether the support rod motor is in a running state.

[0071] Step 2: If the support rod motor is not in a running state, start the support rod motor.

[0072] Step 3: If the support rod motor is in a running state, determine whether the hood has successfully opened / closed to the target opening / closing position.

[0073] Step 4: If the hood has not opened / closed to the target opening / closing position, monitor the second running current and the second running time of the support rod motor.

[0074] It can be understood that if the hood successfully opens / closes to the target opening / closing position, the support rod motor is stopped and the process is ended.

[0075] Step 5: If the second running current exceeds the second current threshold value, or the second running time length exceeds the second time length threshold value, it is determined that the hood opening and closing to the target opening and closing position fails, and the support rod motor is restarted.

[0076] It should be noted that the second current threshold value can be 400mA, and the second time length threshold value can be 2s. The reason why the second running current exceeds the second current threshold value or the second running time length exceeds the second time length threshold value can be that the hood encounters an obstacle, so that the running current and the running time length increase. Therefore, monitoring the second running current and the second running time length of the support rod motor can protect the support rod motor and prolong the service life.

[0077] Step 6: If the number of times that the hood opening and closing to the target opening and closing position fails exceeds the second number threshold value, the support rod motor is turned off.

[0078] It should be noted that the second number threshold value can be 2 times.

[0079] It can be understood that after the support rod motor is turned off, the user can be prompted that the operation fails, the number of failures is cleared, and the current position of the hood is recorded once for anti-collision and anti-pinch stop. If the number of anti-collision and anti-pinch stops at the current position exceeds a third number threshold value, it is determined that the current position is a user-defined position.

[0080] It should be noted that the purpose of recording the user-defined position is to control the electric support rod to drive the hood to open and close to the user-defined position, so that the hood can be stopped at any angle to meet the opening angle requirements of different users. The third number threshold value can be 3 times.

[0081] It should be noted that as shown in Figure 2 , the hood can include a hood assembly, a hood hinge, an electric support rod, a hood lock, a hood primary command device, a hood secondary command device, a hood closing command device, and a hood controller.

[0082] It should be noted that the hood assembly can rotate around the hood hinge. The electric support rod provides power for the rotation of the hood assembly around the hood hinge, and can provide signals of the rotation angle and the rotation speed of the hood.

[0083] The hood primary command device can provide an unlocking signal for the hood lock to switch from the full lock position to the half lock position, and provide a closing signal for the electric support rod. The hood primary command device can be a physical button arranged on the instrument panel, a physical button on the car key, or a virtual button on the central control screen.

[0084] The hood secondary command device can provide an unlock signal for switching the hood lock from the half-lock position to the fully open position, and the hood secondary command device can be arranged at the front of the vehicle, the lower part of the vehicle, or the front section of the hood. Considering safety factors, the arrangement position of the hood secondary command device should be arranged separately from the hood primary command device.

[0085] The hood controller can collect the vehicle speed, gear, rotation angle signal of the electric support rod, rotation speed signal, operating current of the support rod motor, operating time length of the support rod motor, operating current of the hood lock motor, operating time length of the hood lock motor current, unlock signal of the hood primary command device, close signal, and unlock signal of the hood secondary command device. At the same time, the hood controller can control the opening and closing of the hood by analyzing the above signals, and can realize the protection of electric opening false triggering, the identification protection of anti-collision and anti-pinch, and the user intention recognition and embodiment during the opening and closing process.

[0086] The embodiment of the application determines the target locking position of the hood lock in response to receiving the opening and closing command of the hood lock, and obtains vehicle control information, which is used to represent the current running state of the vehicle. Based on the vehicle control information, the hood lock is controlled to switch from the current locking position to the target locking position, and the current locking position and the target locking position satisfy the pre-set switching sequence. If the target locking position does not satisfy the hood opening and closing to the target opening and closing position, the opening and closing command of the hood lock is re-triggered until the target locking position satisfies the hood opening and closing to the target opening and closing position. If the target locking position satisfies the hood opening and closing to the target opening and closing position, the electric support rod is controlled to drive the hood to open and close to the target opening and closing position based on the vehicle control information. When the target locking position of the hood lock satisfies the hood opening and closing to the target opening and closing position, the electric support rod can be controlled to drive the hood to open and close to the target opening and closing position, so that the hierarchical control of the hood lock and the electric support rod on the hood is realized, and the problem of hood opening due to false triggering is avoided. Therefore, the safety of opening and closing the hood is improved to a certain extent, and the driving risk is reduced.

[0087] Based on the same inventive concept, reference is made to Figure 3As shown, this embodiment of the invention provides a vehicle hood control device 10. The vehicle includes a hood, an electric strut, and a hood lock. The electric strut provides driving force for opening and closing the hood, and the hood lock locks the range of hood opening and closing positions. The vehicle hood control device 10 includes: a response unit 110, used to respond to receiving an opening / closing command for the hood lock, determine the target locking position for the hood lock, and acquire vehicle control information, which characterizes the current operating state of the vehicle; a position switching unit 120, used to control the hood lock to switch from the current locking position to the target locking position based on the vehicle control information, wherein the current locking position and the target locking position satisfy a preset switching sequence; a trigger unit 130, used to re-trigger the opening / closing command for the hood lock if the target locking position does not satisfy the requirement to open / close the hood to the target opening / closing position, until the target locking position satisfies the requirement to open / close the hood to the target opening / closing position; and a drive unit 140, used to control the electric strut to drive the hood to open / close to the target opening / closing position based on the vehicle control information if the target locking position satisfies the requirement to open / close the hood to the target opening / closing position.

[0088] It should be understood that further implementation details of the vehicle hood control device 10 in the embodiments of the present invention are described in the foregoing vehicle hood control method, and will not be repeated here for the sake of brevity.

[0089] Based on the same inventive concept, embodiments of the present invention also provide a vehicle, such as Figure 4 As shown, the system includes a memory 404, a processor 402, and a computer program stored in the memory 404 and executable on the processor 402. The processor 402 executes the program to implement the steps described in any embodiment of the vehicle hood control method.

[0090] Among them, Figure 4 In this document, a bus architecture (represented by bus 400) is used. Bus 400 may include any number of interconnected buses and bridges, linking various circuits including one or more processors represented by processor 402 and memory represented by memory 404. Bus 400 may also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. Bus interface 405 provides an interface between bus 400 and receiver 401 and transmitter 403. Receiver 401 and transmitter 403 may be the same element, i.e., a transceiver, providing a unit for communicating with various other devices over a transmission medium. Processor 402 is responsible for managing bus 400 and general processing, while memory 404 can be used to store data used by processor 402 during operation.

[0091] In the embodiment of the present application, the electric supporting rod is controlled to drive the hood to open or close to the target opening or closing position only when the target locking position of the hood lock meets the condition of opening or closing the hood to the target opening or closing position, so that the hierarchical control of the hood lock and the electric supporting rod on the hood is realized, and the problem of opening the hood due to false triggering is avoided. Therefore, the safety of opening and closing the hood is improved to a certain extent, and the driving risk is reduced.

[0092] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions can be stored on or transferred over as one or more instructions or code on a computer-readable medium.
