[0054] As described above, most electric vehicle hoods currently still use the manual opening and closing control method of the engine hood of a fuel vehicle, with the hood kept open by a hydraulic rod or a mechanical strut. Compared with the widespread use of electric tailgates, electric hoods are less commonly used. The original operation method of the hood is inconvenient for electric vehicle users.
[0055] In view of the above problems, the inventors have proposed a control method and device for a car hood after research, which receive a hood control signal of a vehicle to be controlled; obtain hood status information of the vehicle to be controlled, and determine a control strategy for the hood of the vehicle to be controlled based on the hood status information and the control signal; the control strategy includes driving the hood to open, driving the hood to hover, adjusting the opening angle of the hood or driving the hood to close; and controlling the hood of the vehicle to be controlled according to the control strategy.
[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0057] See also Figure 1 , which is a flow chart of a method for controlling a front hood of an automobile provided in an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:
[0058] S101, receiving a front hood control signal of a vehicle to be controlled.
[0059] Users can send control signals for the front hatch in a variety of ways, such as the display screen, remote control key or physical buttons in the car, and the vehicle is equipped with a corresponding communication module to receive these signals. It can be wireless radio frequency (RF), Bluetooth, Wi-Fi or other types of short-range wireless communication technology, or it can be a command transmitted through the vehicle's internal network (such as CAN bus). Normally, the front hatch's operating mode defaults to electric mode, and for safety reasons, the front hatch is controlled when the vehicle is stationary.
[0060] S102: Acquire hood status information of the vehicle to be controlled, and determine a control strategy for the hood of the vehicle to be controlled based on the hood status information and the control signal.
[0061] The control strategy includes driving the front hood to open, driving the front hood to hover, adjusting the opening angle of the front hood, or driving the front hood to close.
[0062] Use various sensors installed on the hood (such as position sensors, angle sensors, gravity sensors, etc.) to collect the current angle of the hood and whether it is completely closed or open. Determine the control strategy based on the acquired hood status information and the received control signal. For example, when the user presses a physical button in the car, the hood controller of the vehicle receives the control signal sent by the physical button in the car and obtains that the hood is in the closed state, then the control strategy is determined to drive the hood to open.
[0063] S103: Control the front hood of the vehicle to be controlled according to the control strategy.
[0064] According to the determined control strategy, the front hood of the vehicle is controlled by controlling related components, for example, the state of the front hood is changed by controlling a support rod or a hydraulic system.
[0065] The control method of the automobile hood provided in this embodiment only needs to send a control signal, for example, by sending a control signal through a display screen or a remote control key, and the system can control the hood according to the vehicle's hood status information and the control signal, thereby improving the convenience of controlling the vehicle's hood through automated means and enhancing the user experience.
[0066] See also Figure 2 , which is a flow chart of another method for controlling a front hood of a vehicle provided in an embodiment of the present application. In this embodiment, the control signal is sent via a display screen. Figure 2 As shown, the method comprises the following steps:
[0067] S201, receiving a front hood control signal of a vehicle to be controlled.
[0068] The control signal is sent via the display screen.
[0069] The display has built-in capacitive or resistive touch sensing technology, which can accurately capture the user's touch actions and convert them into digital signals. In addition to simple clicks, it can also support more complex gesture operations, such as sliding, long pressing, etc., to increase the flexibility of interaction. When the control signal is sent through the display, it means that the user can control the vehicle's front hatch through the in-vehicle display (such as the touch screen of the center console or the dashboard display).
[0070] Optionally, the operating mode of the front hatch can be set through the display screen, for example, changing the electric mode to the manual mode via the display screen.
[0071] Optionally, a default opening angle of the vehicle's front hood is set via a display screen.
[0072] S202: Determine a control strategy for the front hood of the vehicle to be controlled based on the front hood state information and the control signal sent through the display screen.
[0073] The control signal sent by the display screen includes a first turn-on signal, a first hovering signal, a target angle setting signal or a first turn-off signal; the target angle is within a preset angle range.
[0074] The user selects the desired operation (such as opening, closing, hovering or adjusting the angle of the front hood, etc.) by touching the button or icon on the display screen. Figure 3 As shown, the user controls the front hood through the display icon, wherein the user can control the angle of the front hood to a target angle by sliding the display screen, the target angle is within a preset range, and the display screen can show the actual opening angle of the front hood and the process of adjusting the opening angle.
[0075] S203: Control the front hood of the vehicle to be controlled according to the control strategy.
[0076] According to the determined control strategy, the front hatch of the vehicle is controlled by controlling relevant components.
[0077] This embodiment provides another method for controlling the front hood of a car, in which the user sends a control signal through a display screen. This method provides an intuitive operation interface and improves the convenience of user operation.
[0078] See also Figure 4 , which is a flow chart of another method for controlling a front hood of a car provided by an embodiment of the present application. The control signal in this embodiment is sent via a remote control key. Figure 4 As shown, the method comprises the following steps:
[0079] S301, receiving a front hood control signal of a vehicle to be controlled.
[0080] The control signal is sent via a remote control key.
[0081] The remote control key sends control signals through wireless communication technologies such as radio frequency (RF) or Bluetooth low energy (BLE). Through the remote control key, the front hatch of the vehicle can be controlled within an effective distance range.
[0082] S302: Determine a control strategy for the front hood of the vehicle to be controlled based on the front hood state information and a control signal sent by a remote control key.
[0083] The control signal sent by the remote control key includes a second opening signal, a second hovering signal or a second closing signal.
[0084] The operation of the remote control key is set according to the preset rules to distinguish different control signals. The process of controlling the front hatch by the remote control key is as follows:
[0085] After receiving the long press signal sent by the remote control key, if it is obtained that the front hood of the vehicle to be controlled is in the closed state, the control strategy is determined to drive the front hood to open;
[0086] After receiving the long press signal sent by the remote control key, if it is obtained that the front hood of the vehicle to be controlled is in the open state, the control strategy is determined to drive the front hood to close;
[0087] After receiving the short press signal sent by the remote control key, if it is obtained that the front hood of the vehicle to be controlled is in the running state, the control strategy is determined to drive the front hood to hover;
[0088] After receiving the long press signal sent by the remote control key, if it is obtained that the front hood of the vehicle to be controlled is in a hovering state, the control strategy is determined to drive the front hood to run in the opposite direction before the hovering.
[0089] S303: Control the front hood of the vehicle to be controlled according to the control strategy.
[0090] According to the determined control strategy, the front hatch of the vehicle is controlled by controlling relevant components.
[0091] Optionally, the present embodiment also provides a remote control key mislocking process. When the vehicle's hood changes from a half-locked state to a fully locked state, the hood control module will detect whether the key is located inside the front cabin by locating the remote control key's RFID or low-power Bluetooth (BLE) signal. If it is located in the front cabin, the hood will be driven to unlock and a sound and light request will be sent (for example, the horn will sound twice (each cycle is 30ms and paused for 970ms), and the turn signal will flash twice (each cycle is 500ms on and 500ms off)).
[0092] Another method for controlling a car hood provided in this embodiment realizes remote control of the hood in the process of controlling the hood based on a control signal sent by a remote control key, thereby improving the convenience and intelligence level of operation and further improving the user experience.
[0093] See also Figure 5 , which is a flow chart of another method for controlling a front hood of a vehicle provided in an embodiment of the present application. The control signal in this embodiment is sent via a touch switch. Figure 5 As shown, the method comprises the following steps:
[0094] S401, receiving a front hood control signal of a vehicle to be controlled.
[0095] The control signal is sent via a touch switch.
[0096] A touch switch is a touch-sensitive device installed on the outside of the vehicle that allows the user to send control signals by tapping or sliding. For example, a TouchPad switch uses capacitive or resistive touch sensing technology to detect the user's touch and convert it into a digital signal. The control signal sent by the touch switch is transmitted to the central control system or a module dedicated to the front hood control through the vehicle's internal network (such as the CAN bus).
[0097] S402: If the first preset condition is met, a control strategy for the front hood of the vehicle to be controlled is determined based on the front hood state information and the control signal sent through the touch switch.
[0098] The control signal sent by the front hatch includes a third opening signal, a third hovering signal or a third closing signal; the first preset condition is that the user is within a preset range.
[0099] The user can confirm that the touch is within the preset range in a variety of ways, such as by using the remote control key carried by the user. The touch or slide action detected by the touch switch is set according to the preset rules to distinguish different control signals. The process of controlling the front hatch by the touch switch is as follows:
[0100] After receiving the control signal sent by the touch switch, if it is obtained that the front hatch of the vehicle to be controlled is in a closed state, the control strategy is determined to drive the front hatch to open;
[0101] After receiving the control signal sent by the touch switch, if it is obtained that the front hood of the vehicle to be controlled is in an open state, the control strategy is determined to drive the front hood to close;
[0102] After receiving the control signal sent by the touch switch, if it is obtained that the front hatch cover of the vehicle to be controlled is in the running state, the control strategy is determined to drive the front hatch cover to hover;
[0103] After receiving the control signal sent by the touch switch, if it is obtained that the front hood of the vehicle to be controlled is in a hovering state, the control strategy is determined to drive the front hood to run in the opposite direction before the hovering.
[0104] Optionally, the default opening angle of the front hood can be adjusted by a touch switch to meet the requirements of different groups of people for the opening height of the front hood.
[0105] S403: if the first preset condition is not met, based on the front hatch state information indicating that the front hatch is closed, and upon receiving a control signal sent by the mobile device, the front hatch is unlocked;
[0106] If the third opening signal sent by the touch switch is received within a preset time, the control strategy for the front hood of the vehicle to be controlled is determined to drive the front hood to open.
[0107] For example, when the user is far away from the vehicle, that is, the remote control key and Bluetooth key cannot control the vehicle, if someone beside the vehicle (such as a friend or courier, etc.) needs to take something from the front hood and cannot open the door, the owner can disarm the front hood through the mobile device APP. After disarming, the vehicle flashes lights and buzzes to remind. At this time, the person beside the vehicle short presses the TouchPad switch, and the front hood controller drives the front hood to open;
[0108] If the person next to the vehicle does not operate to open the front hood within 30 seconds, the front hood will exit the disarmed state and can no longer be opened by the TouchPad switch.
[0109] S404: Control the front hood of the vehicle to be controlled according to the control strategy.
[0110] According to the determined control strategy, the front hatch of the vehicle is controlled by controlling relevant components.
[0111] Optionally, the operating mode of the front hatch is manually reset to electric mode by touching a switch.
[0112] Another method for controlling a car hood provided in this embodiment can meet the user's control needs in different scenarios by sending a control signal through a touch switch, greatly improving the user's experience and the convenience of the user in controlling the car hood.
[0113] See also Figure 6 , which is a flow chart of another method for controlling the front hood of an automobile provided in an embodiment of the present application. The control signal in this embodiment is sent via a foot switch. Figure 6 As shown, the method comprises the following steps:
[0114] S501: Receive a front hood control signal of a vehicle to be controlled.
[0115] The control signal is sent via a foot switch.
[0116] The foot switch is a sensor (such as an infrared sensor, ultrasonic sensor, etc.) installed at the bottom of the vehicle or a specific location to detect the user's kicking action. These sensors can recognize different kicking modes (for example, single kick, double kick, etc.) to distinguish different control commands. For example, when the user is unable to manually open the front hatch (such as carrying something, etc.), the user can control the front hatch to open or close by kicking the foot switch outside the vehicle. During the opening or closing process, the foot switch is kicked again to make the front hatch hover.
[0117] S502: Determine a control strategy for the front hood of the vehicle to be controlled based on the front hood state information and the control signal sent by the foot switch.
[0118] The control signal sent by the foot switch includes a fourth on signal, a fourth hovering signal or a fourth off signal.
[0119] The kicking action detected by the foot switch is set according to a preset rule to distinguish different control signals. The process of controlling the front hatch by the foot switch is as follows:
[0120] After receiving the control signal sent by the foot switch, if it is obtained that the front hatch of the vehicle to be controlled is in a closed state, the control strategy is determined to drive the front hatch to open;
[0121] After receiving the control signal sent by the foot switch, if it is obtained that the front hood of the vehicle to be controlled is in an open state, the control strategy is determined to drive the front hood to close;
[0122] After receiving the control signal sent by the foot switch, if it is obtained that the front hatch cover of the vehicle to be controlled is in the running state, the control strategy is determined to drive the front hatch cover to hover;
[0123] After receiving the control signal sent by the foot switch, if it is obtained that the front hood of the vehicle to be controlled is in a hovering state, the control strategy is determined to drive the front hood to run in the opposite direction before the hovering.
[0124] S503: Control the front hood of the vehicle to be controlled according to the control strategy.
[0125] According to the determined control strategy, the front hatch of the vehicle is controlled by controlling relevant components.
[0126] The control method of the automobile hood provided in this embodiment can meet the user's control needs in different scenarios by sending a control signal through a foot switch, greatly improving the user's usage experience and the convenience of the user in controlling the automobile hood.
[0127] See also Figure 7 , which is a flow chart of another method for controlling the front hood of an automobile provided in an embodiment of the present application. The control signal in this embodiment is sent via a driver side switch. Figure 7 As shown, the method comprises the following steps:
[0128] S601: Receive a front hood control signal of a vehicle to be controlled.
[0129] The control signal is sent via a driver-side switch.
[0130] The driver's side switch is usually a physical button installed on the door lining or the center console. Once the user operates the driver's side switch, the generated control signal will be transmitted to the central control system or the module specifically responsible for the front hood control through the vehicle's internal network (such as the CAN bus).
[0131] S602: Determine a control strategy for the front hood of the vehicle to be controlled based on the front hood state information and the control signal sent through the driver-side switch.
[0132] The control signal sent by the driving side switch includes a fifth on signal, a fifth hovering signal or a fifth off signal.
[0133] The use of the driver's side switch is set according to preset rules to distinguish different control signals. The process of controlling the front hatch through the driver's side switch is as follows:
[0134] After the driver's side switch is pressed, a control signal is sent. If the front hood of the vehicle to be controlled is in a closed state, the control strategy is determined to drive the front hood to open;
[0135] After the driver's side switch is pressed, a control signal is sent. If the front hood of the vehicle to be controlled is obtained to be in an open state, the control strategy is determined to drive the front hood to close;
[0136] After the driver's side switch is pressed, a control signal is sent. If it is obtained that the front hood of the vehicle to be controlled is in the running state, the control strategy is determined to drive the front hood to hover;
[0137] After the driver side switch is pressed, a control signal is sent. If it is obtained that the front hood of the vehicle to be controlled is in a hovering state, the control strategy is determined to drive the front hood to run in the opposite direction before the hovering.
[0138] S603: Control the front hood of the vehicle to be controlled according to the control strategy.
[0139] According to the determined control strategy, the front hatch of the vehicle is controlled by controlling relevant components.

[0147] According to the change of the Hall number of the front hatch cover support rod, the operation state of the front hatch cover is determined;
[0148] The front hatch support rod is controlled according to the operating state of the front hatch.
[0149] In one feasible implementation, in the electric mode, when the user manually closes or opens the front hood, the front hood control module will assist in driving the front hood to close or open electrically.
[0150] Optionally, according to the Hall signals of the left and right electric struts of the front hood, if there is an obstacle during the movement of the front hood, when the Hall signal change speed reaches the anti-pinch threshold, the front hood support rod is controlled. For example, the electric strut motor is driven to reverse 5% and then stop. After the front hood anti-pinch reaches 5 times within 30 seconds, the front hood control module enters the anti-pinch protection, that is, the electric strut output is prohibited, and an abuse protection reminder is sent to remind the customer. After the front hood control module executes the anti-pinch protection, if it detects that the front hood is opened to the set angle threshold or switched to the fully locked state, the front hood controller exits the anti-pinch protection and can operate normally.
[0151] Optionally, the front hood control module activates thermal protection for the front hood according to preset rules. For example, when a control signal such as a remote control key or a touch switch is received, and the front hood is operated 10 times within 30 seconds and the front hood is operated continuously without reaching the fully locked position and the opening setting position, thermal protection is entered, the electric support rod output is disabled, and an abuse protection reminder is sent through the display screen, instrument panel and buzzer;
[0152] When the front hood controller continuously drives the electric support rod for 40 seconds, it enters thermal protection, disables the electric support rod output, and sends an abuse protection reminder, which is reminded by the large screen, instrument and buzzer;
[0153] During the thermal protection period, if the status information of the front hood obtained satisfies any of the following conditions: the front hood is opened to the set angle threshold, the front hood is switched to the fully locked state, or the front hood is in the thermal protection state, and any of these conditions lasts for more than 10 seconds, the thermal protection is exited and a new control signal is responded to.
[0154] Optionally, the control method of the automobile front hood provided in the above embodiment further includes:
[0155] Receive multi-dimensional data; the multi-dimensional data includes battery voltage and power data, vehicle exterior temperature data, vehicle longitudinal acceleration data, vehicle front hood weight data, and driving force data at various angles of the vehicle front hood support rod;
[0156] Based on the multi-dimensional data, adjusting the pulse width modulation signal using an algorithm;
[0157] The driving force of the front hood support rod is controlled according to the adjusted pulse width modulation signal.
[0158] Pulse Width Modulation (PWM) is a technology used to control power output. It can effectively adjust the speed or torque of the motor by changing the ratio of "on" and "off" of the signal (i.e., the duty cycle). Here, the PWM signal is used to finely control the motor of the support rod, thereby achieving smooth and precise front hood control. The adjusted PWM signal is sent to the drive circuit, which is responsible for directly controlling the motor or hydraulic device in the support rod. This allows the driving force provided by the support rod to be adjusted in real time according to actual needs, whether it is increased or decreased, to keep the front hood at the desired position or angle.
