[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] It is understandable that when the hood lock is open, after the car is ignited, the DA screen of the vehicle usually displays a prompt that the front hood is open, and a prompt sound is played when the vehicle speed exceeds 5km / h, reminding the user to close the hood. If the user does not notice the prompt or ignores the prompt, there is a risk of high-speed driving; and if the hood lock fails during driving, it cannot be identified and responded to in time, which poses a greater safety risk. In order to solve the problem of the risk of the hood flipping up when the hood lock of the above vehicle is opened. Figure 1 A first embodiment of a vehicle control method of the present invention is provided. Figure 1 This is a flow chart of the first embodiment of the vehicle control method proposed by the invention.

[0048] In this embodiment, the vehicle control method includes:

[0049] Step S10: Detect the hood lock status of the vehicle.

[0050] It should be understood that in this embodiment and the following embodiments, the vehicle control system can be used as the execution subject, and the vehicle control system can execute processes such as data collection, processing, analysis, model building, etc. The vehicle control system can also establish a connection with an external device, such as a mobile terminal, for transmitting relevant data.

[0051] It should be noted that the hood lock is a structure used to lock the vehicle hood to the front of the vehicle body. The hood lock states include unlocked state and locked state. In the unlocked state, the hood can be opened directly with a certain external force, for example, the user can directly lift the hood to repair and clean the inside of the hood; in the locked state, the hood cannot be opened by ordinary external force because the structure of the hood lock fixes the hood to the front of the vehicle. The state switching of the hood lock is mainly controlled by the hood lock controller in the vehicle control system.

[0052] It is understandable that in order to determine whether there is a risk of the hood flipping up, it is necessary to first detect the main state of the hood lock. When the hood lock is in a locked state, there is no risk of the hood flipping up; when the hood lock is in an unlocked state, there may be a risk of the hood flipping up if there is an external force.

[0053] In a specific implementation, the detection can be performed by detecting the structural change of the hood lock or by detecting the distance between the hood and the front end of the vehicle. For example, the hood lock state can be determined by directly detecting the structural change of the hood lock through the hood lock sensor, or by detecting the distance between the hood and the front end of the vehicle through the distance sensor. If the distance is large, it is determined that the hood lock is in the unlocked state.

[0054] Step S20: When the hood lock state is in the unlocked state, detecting the current running state of the vehicle.

[0055] It should be understood that whether there is a risk of the hood flipping up depends not only on the hood lock state, but also on the running state of the vehicle. When the vehicle is stationary, the hood will not flip up; while when the vehicle is in motion, the hood of the vehicle is likely to flip up due to external forces caused by movement. Therefore, in order to determine whether there is a risk of the hood flipping up, in this embodiment, it is also necessary to detect the movement state of the vehicle.

[0056] It should be noted that the current operating state refers to the operating state of the vehicle when the hood is detected to see if there is a risk of it flipping up. The current operating state includes a stationary state and a driving state. During the specific detection process, the current operating state of the vehicle can be obtained through the vehicle speed sensor, the accelerator pedal opening sensor inside the vehicle, etc.

[0057] Step S30: When the current operating state is in the driving state, controlling the vehicle speed to be lower than a preset vehicle speed.

[0058] It should be noted that the preset speed is the maximum speed value at which the external force generated will not flip up the hood. When the vehicle is traveling at a speed less than the preset speed, the external force generated will not flip up the hood of the vehicle due to the low speed; when the vehicle is traveling at a speed greater than or equal to the preset speed, the external force generated may cause the hood of the vehicle to flip up. When the vehicle speed is greater than the preset speed, the greater the speed value, the greater the probability of the hood flipping up. In the specific control process, the preset speed can be set according to the actual vehicle. For example, when the vehicle is a small passenger car, the preset speed can be set to 42 kilometers per hour.

[0059] It should be understood that if the vehicle is in a driving state, the hood may be lifted. Therefore, in order to prevent the hood from being lifted, the vehicle speed can be controlled to be lower than a preset speed. When the vehicle speed is lower than the preset speed, the external force generated by the vehicle driving will not cause the hood to be lifted.

[0060] In a specific implementation, when it is determined that the current running state of the vehicle is the driving state, the vehicle can be controlled to continue driving at a speed lower than a preset speed until the vehicle completely stops. In a specific implementation, the preset speed can be set as an upper limit value, and when the vehicle speed reaches the preset speed, the vehicle is controlled to stop accelerating.

[0061] In this embodiment, a vehicle control method is provided, which includes: detecting the hood lock state of the vehicle; when the hood lock state is in the unlocked state, detecting the current running state of the vehicle; when the current running state is in the driving state, controlling the speed of the vehicle to be lower than a preset speed. In the present invention, by detecting the hood lock state and the current running state of the vehicle, when it is determined that the vehicle may have a risk of the hood flipping up, the speed of the vehicle is controlled to keep the vehicle in a low-speed driving state, thereby effectively avoiding the risk of the hood flipping up and reducing the probability of the vehicle colliding.

[0062] Furthermore, after step S10, this embodiment further includes: when the cover lock state is in the unlocked state, sending third prompt information to the mobile terminal to prompt the user.

[0063] It should be understood that when it is detected that the hood lock of the vehicle is in an unlocked state, regardless of whether the vehicle is in driving state, it is necessary to prompt the user to close the hood lock to avoid safety risks.

[0064] It should be noted that the third prompt information is a prompt information that prompts the user that the hood lock of the vehicle is in an unlocked state. In order to avoid the user not being able to know that the hood lock is in an unlocked state when he is not in the vehicle, the third prompt information is directly sent to the mobile terminal to prompt the user.

[0065] In a specific implementation, when the vehicle control system detects that the hood lock is in an unlocked state, it can directly send a third prompt message to the connected mobile terminal through the remote information controller, so that the user knows that the hood lock is in an unlocked state when receiving the third prompt message and can adjust the hood lock state in time.

[0066] In addition, when the hood lock is in the locked state, the hood of the vehicle is locked by the hood lock, and no prompt is required, and the vehicle control system will not limit the vehicle speed.

[0067] Based on the above first embodiment, a second embodiment of the vehicle control method of the present invention is proposed. Figure 2 , Figure 2 This is a schematic diagram of the first flow chart of the second embodiment of the vehicle control method proposed by the invention.

[0068] In this embodiment, the step S30 further includes:

[0069] Step S301: When the current operating state is in a driving state, detecting the current speed of the vehicle.

[0070] It is understandable that during the driving of the vehicle, there may be emergencies such as the user's false triggering or abnormal driving of the hood lock, at which time there is a greater risk of collision. When the vehicle is currently in the driving state, the main factor affecting whether the hood is flipped up is the vehicle's speed. The higher the speed, the greater the external force that the hood is subjected to flipping up, and the greater the risk of the hood flipping up. Therefore, in the process of controlling the vehicle's speed, it is also necessary to understand the vehicle's speed during driving.

[0071] It should be noted that the current vehicle speed refers to the vehicle speed value corresponding to the moment when the vehicle control system detects that the vehicle hood lock is in an unlocked state and the vehicle is in a driving state.

[0072] In a specific implementation, when it is determined that the current running state of the vehicle is in the driving state, the current speed of the vehicle can be obtained through a speed sensor installed in the vehicle; of course, other sensors can also be used to collect parameter values ​​related to the vehicle speed, and then the current speed of the vehicle can be obtained through calculation. For example, the rotation speed of the vehicle wheels can be detected, and then the vehicle speed can be determined based on the rotation speed and the specific size of the wheels.

[0073] Step S302: When the current vehicle speed is greater than a preset vehicle speed, a first prompt message is output and the current vehicle speed is controlled to decrease to the preset vehicle speed.

[0074] It should be noted that after determining the current vehicle speed, there may be two situations: the current vehicle speed is greater than the preset speed and the current vehicle speed is less than the preset speed. When the current vehicle speed is greater than the preset speed, there is a risk that the hood may flip up at any time, and the vehicle needs to be controlled in time to reduce the speed.

[0075] Among them, the first prompt information is used to remind the user that the hood of the vehicle may be opened at any time. The first prompt information has the highest prompt level, which can be achieved by lighting up the DA screen fault light and issuing a prompt sound to directly prompt the user to close the hood lock. For example, the fault light on the DA screen in the vehicle keeps flashing, and the speaker inside the vehicle will issue a prompt sound of "Please lock the hood lock immediately".

[0076] In a specific implementation, when it is detected that the current vehicle speed is greater than the preset speed, the vehicle control system can actively use the automatic emergency braking system to reduce the vehicle speed and output the corresponding first prompt information to prompt the user. During this process, if the user actively accelerates, the vehicle control system will ignore the user's acceleration operation until the current vehicle speed is reduced and maintained below the preset speed.

[0077] The step S302 specifically includes:

[0078] Step S3021: When the current vehicle speed is greater than a preset vehicle speed, detecting whether the hood of the vehicle is flipped up.

[0079] It is understandable that when the vehicle is in the driving state and the current speed is greater than the preset speed, the hood may have been raised during the detection of the current running state and the current speed. In this case, the probability of safety risks due to limited user vision is greatly increased. During the detection of the current running state and the current speed, the hood may not be raised. In this case, timely controlling the current speed of the vehicle to be lowered to below the preset speed can reduce the risk of the hood being raised.

[0080] Step S3022: If not, output a first prompt message and control the current speed of the vehicle to decrease to the preset speed within a first preset time.

[0081] It is understandable that when the hood is not opened, since there is always a risk of the hood opening, it is necessary to control the vehicle speed to be reduced in the shortest possible time. In this embodiment, a first preset time can be set, and the vehicle control system reduces the current vehicle speed to below the preset speed within the first preset time. Among them, the first preset time is the emergency braking time, and the first preset time can be within 30 seconds. For example, the vehicle control system can actively use the automatic emergency braking system to reduce the current vehicle speed to the preset speed within 30 seconds and output the corresponding first prompt information to prompt the user.

[0082] After step S3021, the following steps are also included:

[0083] Step S3023: If yes, obtain environmental perception information of the environment in which the vehicle is located.

[0084] It should be understood that when it is determined that the current speed of the vehicle is greater than the preset speed and the hood has been raised, the vehicle speed is high and the user's driving field of vision is severely limited. The user can no longer drive the vehicle normally, which can easily lead to a collision.

[0085] It should be noted that the environmental perception information is information about other vehicles, obstacles, etc. in the environment that the vehicle is currently in. The environmental perception information can be obtained through devices such as laser radar and ultrasonic sensors.

[0086] Step S3024: Initiate assisted driving to control the driving state of the vehicle based on the environmental perception information.

[0087] In order to avoid the risk of collision caused by the user's inability to drive the vehicle normally, in this embodiment, environmental perception information of the vehicle's environment can be obtained, and then assisted driving can be used to control the vehicle's driving state to avoid possible collisions.

[0088] In specific implementation, environmental perception information of the vehicle's environment can be obtained through devices such as laser radar and ultrasonic sensors installed on the vehicle, and then assisted driving can be started. The assisted driving can directly control the vehicle's driving according to the environmental perception information until the vehicle is no longer at risk of collision. The assisted driving reduces the speed of the vehicle and controls the vehicle to stop safely.

[0089] Reference Figure 3 , Figure 3 The second flowchart of the second embodiment of the vehicle control method proposed by the invention further includes the following steps after step S301:

[0090] Step S303: When the current vehicle speed is not greater than the preset vehicle speed, a first prompt message is output, and the current vehicle speed is maintained not greater than the preset vehicle speed.

[0091] In addition, in this embodiment, the current speed of the vehicle may not be greater than the preset speed. In this case, the risk of the hood of the vehicle flipping up is very small. The current speed of the vehicle is maintained at a speed not greater than the preset speed, and the vehicle can still be driven normally until it stops. At the same time, a prompt message is output to remind the user that the hood lock of the vehicle is in an unlocked state and needs to be adjusted to a locked state in a timely manner. For example, when the vehicle is driving at a low speed, the vehicle speed is detected in real time, and the vehicle speed is controlled to be maintained below the preset speed until the user stops normally according to the first prompt message.

[0092] Based on the above-mentioned first embodiment or second embodiment, a third embodiment of the vehicle control method of the present invention is proposed. Figure 4 , Figure 4 This is a flow chart of the third embodiment of the vehicle control method proposed by the invention.

[0093] In this embodiment, after step S20, the following steps are further included:

[0094] Step S40: when the current running state is in a stationary state, output a second prompt message and detect a gear change of the vehicle.

[0095] It should be understood that when the hood lock of the vehicle is in an unlocked state and the current running state of the vehicle is in a stationary state, the vehicle is not moving, and the hood will not be flipped up by a large external force, the second prompt information can be output to prompt the user. After the second prompt information is output, in order to prevent the user from starting the vehicle when the hood lock is unlocked, the gear position of the vehicle can also be detected.

[0096] It should be noted that the second prompt information may be at least one of lighting up the hood fault light in the display panel, a prompt sound, etc. The gear change includes switching from the parking gear to the driving gear, or switching from the driving gear to the parking gear.

[0097] In a specific implementation, when it can be determined that the hood lock is in an unlocked state, the body controller can output a prompt signal through the CAN bus to provide a hood lock prompt in the display panel. For example, the hood logo flashes a yellow warning light. After the second prompt information is output, it is also necessary to detect the gear change of the vehicle in real time to avoid the vehicle starting to drive when the hood lock is in an unlocked state. In this embodiment, since the vehicle is stationary, it is mainly necessary to detect whether the gear of the vehicle is switched from the parking gear to the driving gear. For example, it is detected whether the gear of the vehicle is switched from the P gear to the D gear, or from the P gear to the R gear.

[0098] Step S50: when the gear position is changed from the parking gear position to the driving gear position, outputting inquiry information on whether to continue the operation, and receiving an operation instruction fed back by the user according to the inquiry information.

[0099] It should be understood that when the hood lock is in the unlocked state, the user may still need to use the vehicle, for example, the hood lock fails to lock normally and the user needs to drive the vehicle to a repair center; or the user continues to use the vehicle and may not know that the hood lock is in the unlocked state. In this embodiment, the vehicle can also be controlled to travel when the hood lock is in the unlocked state.

[0100] It should be noted that the inquiry information is output to the user to inquire whether to continue using the vehicle when the hood lock is in the unlocked state. The operation instruction is the instruction fed back by the user according to actual needs. The operation instruction may include a continue operation instruction and a stop operation instruction. In the case of receiving the continue operation instruction, the vehicle control system may control the vehicle to start and drive according to the instruction input by the user. In the case of receiving the stop operation instruction, the vehicle control system no longer controls the vehicle according to the instruction input by the user and maintains the current static state of the vehicle.

[0101] In a specific implementation, when the vehicle control system detects that the gear has changed from the parking gear to the driving gear, it can send an inquiry message to the user through the DA device or the remote control unit, and then receive an operation instruction from the user in response to the inquiry message.

[0102] Step S60: When the operation instruction is a continue operation instruction, a first prompt message is output, and the current speed of the vehicle is controlled not to be greater than the preset speed.

[0103] It should be understood that when the operation instruction received from the user is a continue operation instruction, it means that the user needs to continue using the vehicle with the hood lock unlocked. In order to avoid the risk of the hood flipping up, the speed of the user driving the vehicle can be controlled to keep the speed below the preset speed, and output a first prompt message to prompt the user that the hood lock is unlocked. The prompt level of the first prompt message is greater than the prompt level of the second prompt message. The higher the prompt level, the more types of prompts and the stronger the prompt intensity.

[0104] After step S50, the method further includes:

[0105] Step S70: When the operation instruction is a stop operation instruction, the driving gear position of the vehicle is switched to a parking gear position.

[0106] It is understandable that when the user gives a stop operation instruction according to the inquiry information, the user is not in urgent need of using the current vehicle, and the vehicle control system can also automatically switch the vehicle gear position to the parking gear position. For example, when the user can use other vehicles or other modes of transportation, the user may forget to switch the gear position to the parking gear position after giving a stop operation instruction, which may cause the vehicle not to park, thus causing risks. Therefore, in this embodiment, when receiving a stop operation instruction, the vehicle's driving gear position can be directly switched to the parking gear position to avoid other accidents.

[0107] In addition, to achieve the above purpose, refer to Figure 5 The present invention also provides a vehicle control system, which is used to execute the vehicle control method recorded in any of the above embodiments.

[0108] The vehicle control system comprises:

[0109] Body controller BCM;

[0110] A hood lock sensor 10, an environment sensing sensor 20, a hood lock controller 30, a speaker controller 40, a warning light controller 50, an emergency brake controller 60 and a vehicle computer 70 connected to the vehicle body controller BCM;

[0111] A remote information controller 80 connected to the vehicle computer 70 .

[0112] Among them, the body controller BCM can be connected to the speaker controller 40, the warning light controller 50 and the hood lock controller 30 through the LIN bus, and connected to the environment perception sensor 20, the emergency brake controller 60 and the vehicle computer 70 through the CAN bus.

[0113] It should be understood that the body controller BCM can connect the connected speaker controller 40, the warning light controller 50 and the hood lock controller 30 according to the collected information and the instructions output by the user, and control the status of the environment perception sensor 20, the emergency brake controller 60 and the vehicle computer 70 through the CAN bus. The speaker controller 40 is a controller for controlling the prompt sound in the output prompt information, and the warning light controller 50 is a controller for controlling the light information in the prompt information. The hood lock controller 30 is a controller for controlling the state of the hood lock, which can control the hood lock to switch from the unlocked state to the locked state, or from the locked state to the unlocked state. The environment perception sensor 20 is a sensor for sensing the environmental information near the vehicle, and the environment perception sensor 20 can be an ultrasonic sensor or a laser radar. The vehicle computer 70 can be a DA device in the vehicle, which is used for information exchange between the vehicle and the mobile terminal. The remote information controller 80 is a controller for controlling the information transmission between the vehicle and the mobile terminal.

[0114] In a specific implementation, the body controller BCM can detect the hood lock state through the hood lock sensor 10; when the hood lock state is in the unlocked state, the body controller BCM can detect the current running state of the vehicle; and when the current running state is in the driving state, the body controller BCM controls the vehicle speed to be reduced to a preset speed through the emergency brake controller 60. Of course, when the hood lock is in the unlocked state, the body controller BCM can also send a third prompt message to the mobile terminal through the vehicle machine 70 and the remote information controller 80. The body controller BCM can also output the second prompt message by controlling one of the speaker controller 40 and the prompt light controller 50 to be in the working state, and output the first prompt message by controlling the speaker controller 40 and the prompt light controller 50 to be in the working state. When the hood lock has been flipped up, the environmental perception information of the environment in which the vehicle is located can also be detected through the environmental perception sensor 20; then the body controller BCM starts the assisted driving based on the environmental perception information to control the driving state of the vehicle.

[0115] In addition, to achieve the above-mentioned purpose, the present invention also provides a vehicle, in which the above-mentioned vehicle control system is arranged.

[0116] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
