[0067] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for illustrating and explaining the present application, and are not used to limit the present application.

[0068] Figure 1 Flowchart of an electric front cover control method in an embodiment of the present application. As Figure 1 shown, the method can be implemented as the following steps S101 - S105:

[0069] In step S101, a trigger signal for opening the front cover is received;

[0070] In step S102, it is determined whether the vehicle currently meets the front cover opening condition;

[0071] In step S103, when the vehicle currently meets the front cover opening condition, control the electric front cover lock to perform an unlocking action;

[0072] In step S104, after the electric front cover lock performs the unlocking action, the front cover is popped up to a preset height by a pop-up spring;

[0073] In step S105, when the front cover is popped up to the preset height, start the mechanical drive device to fully open the front cover.

[0074] A trigger signal for opening the front cover is received. The trigger signal includes at least one of the following: a physical button trigger signal in the cab; a remote control key trigger signal; a mobile phone APP remote control signal; a voice control trigger signal.

[0075] It is determined whether the vehicle currently meets the front cover opening condition. The gear state of the vehicle and the current state of the front cover are obtained; the system will obtain the gear state of the vehicle and the current state of the front cover in real time through the sensor network and communication bus inside the vehicle. The gear state information can accurately reflect whether the vehicle is currently in the P gear (parking gear), R gear (reverse gear), N gear (neutral gear), or D gear (forward gear), etc. The front cover state information can determine whether the front cover is in the open state or the closed state.

[0076] When the vehicle is in the P gear and the front hood is in the closed state, it is determined that the vehicle currently meets the front hood opening condition; this is because the P gear is a safety gear when the vehicle is parked. In this gear, the vehicle's transmission system is separated from the engine, and the vehicle will not move accidentally, thus providing safety protection for the front hood opening operation. At the same time, the fact that the front hood is in the closed state indicates that the front hood has not been opened yet and normal opening operations can be carried out.

[0077] When the vehicle is not in the P gear or the front hood is already in the open state, it is determined that the vehicle currently does not meet the front hood opening condition. If the vehicle is not in the P gear, for example, during driving or in other non-parking gears, opening the front hood may affect the vehicle's stability and even pose a safety hazard. And if the front hood is already in the open state, it is obviously unnecessary to perform the opening operation again.

[0078] When the vehicle currently meets the front hood opening condition, control the electric release of the front hood lock to perform the unlocking action. To ensure vehicle safety and prevent illegal opening of the front hood, before controlling the electric release of the front hood lock to perform the unlocking action, the system will start a strict vehicle anti-theft authentication process. When the vehicle currently meets the front hood opening condition, start the vehicle anti-theft authentication; the system will obtain the anti-theft status information of the vehicle through the communication interface with the vehicle anti-theft system and verify the legality and validity of the trigger signal. After obtaining the instruction of successful anti-theft authentication, the system will perform an electric operation on the front hood to switch the front hood lock from the locked state to the unlocked state, thus preparing for the front hood to pop up.

[0079] After the electric release of the front hood lock performs the unlocking action, use the pop-up spring to pop up the front hood to a preset height. After the electric release of the front hood lock successfully performs the unlocking action, the pop-up spring inside the front hood exerts an upward thrust on the front hood, causing the front hood to gradually pop up from the closed state to reach the preset height. This preset height is carefully designed and tested to ensure that the front hood has enough opening angle for subsequent user operations and will not interfere with other vehicle components due to excessive popping up.

[0080] When the front hood pops up to the preset height, start the mechanical drive device to fully open the front hood to ensure that the front hood can be stably and reliably opened to the position required by the user, providing a good user experience.

[0081] When it is detected that the front cover fails to pop up properly, stop the operation of the mechanical drive device, send a fault prompt signal, and record the fault log. For example, when the popping-up height does not reach the preset value or there is a jam during the popping-up process, it indicates that the front cover fails to pop up properly. The system will quickly send a stop command to the mechanical drive device, cut off the power supply of the motor, and stop the mechanical drive device from operating to avoid more serious faults or damages caused by continuous driving. At the same time, the system will send a fault prompt signal to the user through the prompt device inside the vehicle (such as the warning light on the dashboard, the sound alarm, etc.), informing the user that there is an abnormality during the opening process of the front cover and the user needs to pay attention and handle it in time. To facilitate subsequent fault troubleshooting and repair, the system will record the relevant information of this fault (such as the fault occurrence time, fault type, trigger signal source, etc.) in detail in the fault log. The maintenance personnel can quickly locate the cause of the fault by reading the fault log, improving the repair efficiency.

[0082] To ensure that the front cover does not hit an obstacle during the popping-up process and does not affect the normal use of the user, this application can also perform real-time obstacle monitoring during the process of the popping-up spring popping up the front cover to the preset height or the mechanical drive device fully opening the front cover, and dynamically determine the opening height according to the monitoring result. Specifically, during the opening process of the front cover, obtain the obstacle monitoring information, where the opening process of the front cover includes the process of the popping-up spring popping up the front cover to the preset height and the process of starting the mechanical drive device to fully open the front cover, and the obstacle monitoring information includes whether there is an obstacle and the obstacle position information; when there is an obstacle, determine the opening height of the front cover according to the obstacle position information; when there is no obstacle, fully open the front cover.

[0083] Judge whether there is an obstacle according to the preset safety distance threshold (for example, 10 cm). If the distances detected by all sensors are greater than the safety distance threshold, the front cover continues to pop up at the normal speed and angle. When a sensor detects that the distance is less than the safety distance threshold, the control algorithm will immediately reduce the popping-up speed of the front cover and recalculate the popping-up angle of the front cover. After adjusting the popping-up angle and speed, if the sensor detects that the distance to the obstacle gradually increases, it means that the front cover is successfully avoiding the obstacle. At this time, the control algorithm will gradually restore the normal popping-up speed and angle of the front cover until the preset opening angle is reached. If after multiple adjustments of the popping-up angle and speed, the sensor still detects that the distance is less than the safety distance threshold, it means that the front cover cannot avoid the obstacle. At this time, the control algorithm will stop the popping-up action of the front cover and send a fault prompt signal to inform the user that an obstacle is encountered during the opening process of the front cover and needs to be handled manually.

[0084] In addition, an emergency stop button can be set in the vehicle cab / remote control key / mobile phone APP. When the user discovers that an obstacle may be encountered or an abnormal situation occurs during the process of the front hood popping up, the user can press this button to immediately stop the action of the front hood popping up. Furthermore, a way of manual intervention is provided for the user, increasing the safety and reliability of the system.

[0085] The beneficial effects of this application are as follows: receiving a trigger signal for opening the front hood; determining whether the vehicle currently meets the front hood opening condition; when the vehicle currently meets the front hood opening condition, controlling the electric release of the front hood lock to perform an unlocking action; after the electric release of the front hood lock performs the unlocking action, making the front hood pop up to a preset height through a pop-up spring; when the front hood pops up to the preset height, starting a mechanical driving device to fully open the front hood. This application can realize the electric opening of the front hood, effectively improving the convenience of using the front trunk. Moreover, by replacing the electric strut with a mechanical driving device, compared with the traditional electric front hood release device, the cost is saved.

[0086] In one embodiment, the above step S102 can be implemented as the following steps A1 - A3:

[0087] In step A1, obtain the gear state of the vehicle and the current state of the front hood;

[0088] In step A2, when the vehicle is in the P gear and the front hood is in the closed state, determine that the vehicle currently meets the front hood opening condition;

[0089] In step A3, when the vehicle is not in the P gear, or the front hood is already in the open state, determine that the vehicle currently does not meet the front hood opening condition.

[0090] In one embodiment, the trigger signal includes at least one of the following:

[0091] Trigger signal of a physical button in the cab;

[0092] Trigger signal of the remote control key;

[0093] Remote control signal of the mobile phone APP;

[0094] Trigger signal of voice control.

[0095] In one embodiment, before controlling the electric release of the front hood lock to perform the unlocking action, the method can also be implemented as the following steps B1 - B2:

[0096] In step B1, start the vehicle anti-theft authentication;

[0097] In step B2, when the vehicle anti-theft authentication passes, allow the unlocking action to be performed.

[0098] In one embodiment, the method can also be implemented as the following steps:

[0099] When it is detected that the front cover fails to pop up normally, stop the mechanical drive device and

[0100] send out a fault prompt signal,

[0101] and record the fault log.

[0102] Figure 2 FIG. is a schematic structural diagram of an electric front cover in an embodiment of the present application, which is used for the electric front cover control method described in any of the above embodiments. As Figure 2 shown, the electric front cover includes:

[0103] An electrically released front cover lock 201, which is used for locking and electrically unlocking the front cover, and is provided with a pop-up spring to raise the front cover to a preset height after the lock is unlocked;

[0104] A mechanical drive device 202, which is used to apply a lifting force greater than the self-gravity of the front cover to the front cover after the lifting height of the front cover reaches the preset height, so that the front cover automatically lifts;

[0105] A signal acquisition device 203, which is arranged on the electrically released front cover lock and is used to detect the switch state signal of the front cover;

[0106] An electrically opened front cover controller 204, which is connected to the signal acquisition device to judge the switch state of the front cover, is connected to the vehicle gear control system to judge the gear information of the vehicle, and is connected to the electrically released front cover lock to control the rotation of the motor on the lock, so as to realize the electric unlocking of the front cover;

[0107] An auxiliary front cover closer 205, which is arranged on the inner panel of the front cover and helps to close the front cover through manual operation. The auxiliary front cover closer is manifested as making a flanging feature on the inner panel of the front cover and then sleeving a rubber protective cover to form a rubber handle for the user to manually operate to close the front cover.

[0108] Figure 3 FIG. is a flow chart of the opening of the electric front cover in an embodiment of the present application. In combination with Figure 2 the device, when the user sends an instruction to open the front cover to the electrically opened front cover control device in the form of a mobile phone / central control screen / key / voice / gesture instruction, etc., after receiving the instruction to open the front cover, the vehicle electrically opened front cover controller judges whether the vehicle state meets the front cover opening condition. For the specific judgment process, detect information such as the switch state of the front cover through the signal acquisition device, and connect to the vehicle gear control system to judge the gear information of the vehicle. Of course, it is also possible to judge whether there is a heavy object placed on the vehicle front cover according to the information collected by the pressure sensor or camera, etc.

[0109] If the conditions are met, that is, when the front cover is in the closed state, the current vehicle is in the P gear, and there is no heavy object placed on the vehicle front cover, then the front cover lock release motor is energized to unlock the front cover. After the front cover is unlocked, it is bounced up by the locking spring to a preset height. After the front cover bounces up to the preset height, the mechanical driving device applies a lifting force greater than the self-gravity of the front cover to automatically lift the front cover.

[0110] If the front cover opening conditions are not met, corresponding reasons are feedback according to the reasons for not meeting the opening. When the front cover is already in the open state, "the front cover is already open" is feedback; when the vehicle is not in the P gear, then "please place the vehicle in the P gear and then open the front cover" is feedback; when there is a heavy object placed on the vehicle front cover, then "please remove the heavy object and then open the front cover" is feedback.

[0111] In one embodiment, to ensure that the front cover does not hit an obstacle during the bouncing process and does not affect the normal use of the user, a plurality of obstacle sensors, such as ultrasonic radars, infrared sensors or cameras, etc., can be installed at the edge of the front cover and key positions that may come into contact with obstacles. The signal acquisition device is also used to collect the monitoring information of the plurality of obstacle sensors, determine whether there is an obstacle within a preset safe distance threshold range for the opening / closing of the front cover according to the opening / closing state of the front cover, and obtain the obstacle position information. The electric opening front cover controller can also be used to, when it is determined that there is an obstacle within the safe distance threshold range, determine the opening height of the front cover according to the obstacle position information. When the front cover opening conditions are met, the front cover is controlled to open according to the opening height. In addition, an emergency stop button can be set in the vehicle cab / remote control key / mobile phone APP. When the user finds that the front cover may hit an obstacle or abnormal situation during the bouncing process, the button can be pressed to immediately stop the bouncing action of the front cover. Furthermore, a manual intervention method is provided for the user, increasing the safety and reliability of the system.

[0112] Through the present application, the electric opening of the front cover can be realized, effectively improving the convenience of using the front trunk. And, by replacing the electric strut with a mechanical driving device, compared with the traditional electric front cover release device, the cost is greatly saved. In addition, by setting an auxiliary cover closing device, the bad use experience such as dirty hands brought to the user when manually pressing the front cover to close is avoided.

[0113] In one embodiment, the signal acquisition device can send the switch state signal of the front cover to the electric opening front cover controller so that the electric opening front cover controller controls the unlocking of the electric release front cover lock according to the signal.

[0114] In one embodiment, after receiving the front cover opening instruction, the electric opening front cover controller first determines whether the vehicle state meets the front cover opening conditions. If it is met, the front cover lock release motor is energized to unlock the front cover.

[0115] In one embodiment, the form of the auxiliary front cover closer is to create a flanging feature on the inner panel of the front cover and then put on a rubber protective cover to form a rubber handle for the user to manually operate to close the front cover.
