Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth such as the particular system architecture, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

The technical scheme of the application is described below through specific examples.

Referring to fig. 1, a schematic diagram of a vehicle according to an embodiment of the present application is shown. As shown in fig. 1, a vehicle 1 may include an in-vehicle terminal 11 and a gear control module 12. The first signal output port of the vehicle-mounted terminal 11 may be connected to the first signal input port of the gear control module 12. After the user has started the automatic parking function, the in-vehicle terminal 11 can acquire the driver-side seatbelt state and the driver-side door state in the vehicle of the vehicle in the start state of the vehicle. The vehicle-mounted terminal 11 may execute the gear control method provided in the embodiment of the method according to the obtained safety belt state and the vehicle door state, so as to realize the gear control function. When the in-vehicle terminal 11 determines that the pedal state satisfies the preset condition, the seat belt state is the unbuckled state, and the door state is the open state, the in-vehicle terminal 11 may send a corresponding parking instruction to the gear control module 12 to switch the gear of the vehicle to the parking gear. The shift control module 12 may switch the shift position of the vehicle to the parking position in response to the parking instruction transmitted from the in-vehicle terminal 11.

Referring to fig. 2, a schematic diagram of a vehicle gear control method provided by an embodiment of the present application may specifically include the following steps:

S201, acquiring a state of a seat belt on a driver side and a state of a vehicle door.

In the present embodiment, when the driver needs to use the automatic parking function of the vehicle, the driver may enable the automatic parking function of the vehicle through an automatic parking button on the vehicle, or enable the automatic parking function of the vehicle through an automatic parking control on a vehicle main control screen. After the user starts the automatic parking function, the vehicle-mounted terminal can acquire a plurality of state information of the vehicle in a starting state of the vehicle, so that when the state information meets a parking condition preset by a developer, the vehicle gear is automatically switched to the parking gear. The status information acquired by the vehicle-mounted terminal may include, but is not limited to, a pedal status of the vehicle, a seat belt status on the driver side, and a door status on the driver side. Specifically, the in-vehicle terminal may continuously acquire a pressure value of the pedal through a pressure sensor mounted on the pedal, and determine a pedal state of the vehicle according to the acquired pressure value. When the pressure value obtained by the vehicle-mounted terminal is greater than zero, the vehicle-mounted terminal can determine that the pedal is in a depressed state. The vehicle-mounted terminal can acquire the state of the safety belt at the driver side through the safety belt signals transmitted by the air bag control module. The vehicle-mounted terminal can also acquire the door state of the driver side through the door signal transmitted by the vehicle body control module on the vehicle.

In one possible implementation, after the vehicle transitions from the running state to the stopped state, i.e., after the running speed of the vehicle transitions from greater than 0 to less than or equal to the speed threshold, the vehicle-mounted terminal may acquire the driver-side seatbelt state and the driver-side door state to determine whether the driver is ready to leave the driving seat. The vehicle-mounted terminal can acquire the running speed of the vehicle through a wheel speed sensor on the vehicle or an electronic stability system (Electronic Stability Program, ESP) on the vehicle.

In one possible implementation, the vehicle-mounted terminal may acquire the gear information in the current state of the vehicle after the vehicle transitions from the running state to the stopped state. When the shift information acquired by the vehicle-mounted terminal is any other shift than the parking shift (P-shift), the vehicle-mounted terminal may acquire a pedal state, a seat belt state, and a door state of the vehicle to perform an automatic parking function. Specifically, when the in-vehicle terminal determines that the shift position information of the vehicle is any other shift position other than the parking shift position, such as a forward shift position (D-shift position), a reverse shift position (R-shift position), a manual shift position (M-shift position), a motion shift position (S-shift position), a low shift position (L-shift position), the in-vehicle terminal may acquire a pedal state, a driver-side seatbelt state, and a driver-side door state of the vehicle to perform an automatic parking function according to the pedal state, the seatbelt state, and the door state. The state of the seat belt on the driver side may be an unbuckled state or a buckled state. The driver-side door state may be an open state or a closed state.

In one possible implementation manner, when the vehicle is shifted from the driving state to the stop state and the gear information of the vehicle is any other gear except the parking gear, the state information acquired by the vehicle-mounted terminal may further include a driving state of the driver, and the vehicle-mounted terminal may perform the automatic parking function according to the driving state of the driver. Specifically, the vehicle-mounted terminal may continuously acquire a driving photograph of the driver through the vehicle-mounted camera on the vehicle. After the vehicle-mounted terminal acquires the driving photo of the driver, the acquired driving photo can be input into a state model preset by a developer, so that a driving state corresponding to the driving photo can be generated through the state model. When the driving state output by the state model is a state of preparing to get off, the vehicle-mounted terminal can send a parking instruction to a gear control module of the vehicle so as to switch the gear of the vehicle into a parking gear. The state model may be trained by any neural network model known to those skilled in the art, and the embodiment of the present application is not limited to the state model specifically.

S202, if the pedal state meets the preset pedal condition, the state of the safety belt on the driver side is in an unbuckled state and the state of the vehicle door is in an open state, the gear of the vehicle is switched to the parking gear.

In this embodiment, after acquiring the pedal state, the seat belt state and the door state of the vehicle, the vehicle-mounted terminal may determine whether the pedal state of the vehicle satisfies a pedal condition set in advance by a developer, and determine whether the seat belt state on the driver side is an unbuckled state and the door state on the driver side is an open state. If the vehicle-mounted terminal determines that the pedal state meets the pedal condition, the state of the safety belt on the driver side is an unbuckled state, and the state of the vehicle door on the driver side is an open state, the vehicle-mounted terminal can determine that the driver is in a pre-release state, and the vehicle-mounted terminal can send a parking instruction to a gear control module of the vehicle so as to switch the gear of the vehicle into a parking gear.

In one possible implementation manner, if the state information acquired by the vehicle-mounted terminal is at least one of the pedal state not meeting the pedal condition, the door state of the driver side being in the closed state, and the seat belt state being in the fastened state, the vehicle-mounted terminal may determine that the driver is not in the pre-off state, and the vehicle-mounted terminal may maintain the current gear of the vehicle unchanged. In addition, the vehicle-mounted terminal can continuously acquire the pedal state of the vehicle, the door state of the driver side and the safety belt state of the driver side so as to continuously judge whether the driver is in a pre-off state or not, and whether the gear needs to be switched to the parking gear or not.

In one possible implementation, the vehicle-mounted terminal may acquire the gradient value of the current position of the vehicle through a gradient sensor on the vehicle after determining that the pedal state satisfies the pedal condition, the state of the seat belt on the driver side is an unbuckled state, and the state of the door on the driver side is an open state. After the vehicle-mounted terminal acquires the gradient value, the vehicle-mounted terminal can judge whether the gradient value of the current position of the vehicle is larger than or equal to a gradient threshold preset by a developer. If the vehicle-mounted terminal determines that the gradient value of the current position of the vehicle is greater than or equal to the gradient threshold value, the vehicle-mounted terminal can switch the gear of the vehicle to the parking gear. If the vehicle-mounted terminal determines that the gradient value of the current position of the vehicle is smaller than the gradient threshold value, the vehicle-mounted terminal can maintain the current gear of the vehicle unchanged and generate second text prompt information and/or second sound prompt information. The vehicle-mounted terminal can display the second text prompt information through display equipment preset by a developer and/or play the second text prompt information through sound equipment preset by the developer so as to inform a driver that the vehicle is at a sliding risk. The vehicle-mounted terminal can also generate second icon information so as to flash a driving icon corresponding to the second icon information on the instrument panel, so that a driver is informed of the risk of sliding the vehicle.

In one possible implementation, the vehicle-mounted terminal may also acquire a gradient value of the current position of the vehicle through a gradient sensor on the vehicle before acquiring the pedal state, the seat belt state, and the door state. If the vehicle-mounted terminal determines that the gradient value of the current position of the vehicle is greater than or equal to the gradient threshold value, the vehicle-mounted terminal can acquire the pedal state, the safety belt state and the vehicle door state so as to execute the automatic parking function through the acquired state information. If the vehicle-mounted terminal determines that the gradient value of the current position of the vehicle is smaller than the gradient threshold value, the vehicle-mounted terminal can not acquire state information such as pedal state, safety belt state, vehicle door state and the like. By the method provided by the embodiment, the vehicle-mounted terminal can determine whether the automatic parking function needs to be executed according to the gradient value, so that parameters needing to be acquired by the vehicle-mounted terminal are reduced, and energy consumption is reduced.

In this embodiment, when the gradient value is greater than or equal to the gradient threshold value, the vehicle-mounted terminal may switch the vehicle gear to the parking gear, so as to avoid a sliding event caused by forgetting to switch the vehicle gear to the parking gear when the driver gets on or off the ramp, improve the safety coefficient of the vehicle, and avoid the user injury caused by the movement of the vehicle.

In one possible implementation, after the vehicle terminal shifts the vehicle gear to the parking gear, a third text prompt message and/or a third voice prompt message may be generated. The vehicle-mounted terminal can display the third text prompt information through display equipment preset by a developer and/or play the third sound prompt information through sound equipment preset by the developer so as to inform a driver that the vehicle-mounted terminal executes automatic parking operation, and the current gear of the vehicle is a parking gear. The vehicle-mounted terminal can also generate third icon information so as to flash a driving icon corresponding to the third icon information on the instrument panel to inform a driver that the vehicle-mounted terminal executes automatic parking operation, and the current gear of the vehicle is a parking gear.

In the present embodiment, the in-vehicle terminal can determine whether the driver is ready to leave the driving position, that is, whether the driver is in the pre-unseated state, through the door state on the driver side, the seatbelt state on the driver side, and the pedal state. When the vehicle-mounted terminal determines that the vehicle door state is an open state, the safety belt state is an unbuckled state and the pedal state meets the pedal condition, the vehicle-mounted terminal can determine that the driver is about to leave the driving position, and at the moment, the vehicle-mounted terminal can switch the gear of the vehicle into the parking gear. By the method provided by the embodiment, when a driver is ready to leave a driving position, the vehicle-mounted terminal timely switches the gear of the vehicle to the parking gear so as to avoid a sliding event.

In practice, when the driver gets off the vehicle, the driver may open the door on the driver side and unwind the seat belt on the driver side. At the same time, the driver may have one foot lightly stepped on the brake pedal and the other foot already left the vehicle, at which point no rolling event will occur even if the vehicle is parked on a hill because the driver lightly steps on the brake pedal. However, if the driver does not shift the vehicle into the park position at this time, a slip event occurs when the driver leaves the brake pedal. In this embodiment, since the vehicle-mounted terminal can switch the gear of the vehicle to the parking gear when the brake pedal is in the depressed state, the method provided in this embodiment can avoid a sliding event caused by the above scenario, thereby improving the safety factor of the vehicle.

Fig. 3 shows a flowchart of a specific implementation of a control method S202 for a vehicle gear according to a second embodiment of the present application. Referring to fig. 3, compared to the embodiment shown in fig. 2, in the method for controlling a vehicle gear provided in this embodiment, S202 includes: s301 to S302 are specifically described below:

s301, acquiring a first pedal state of a brake pedal and a second pedal state of an accelerator pedal.

In this embodiment, the pedal states acquired by the in-vehicle terminal may include a first pedal state corresponding to a brake pedal of the vehicle and a second pedal state corresponding to an accelerator pedal of the vehicle. The vehicle-mounted terminal can determine a first pedal state of the first pedal through an opening value of the first pedal, and determine a second pedal state of the second pedal through an opening value of the second pedal. Specifically, when the opening value of the first pedal is greater than the opening threshold value preset by the developer, the vehicle-mounted terminal may determine that the first pedal state is a depressed state; when the opening value of the first pedal is smaller than or equal to the opening threshold value preset by the developer, the vehicle-mounted terminal can determine that the first pedal state is an un-depressed state. When the opening value of the second pedal is larger than an opening threshold value preset by a developer, the vehicle-mounted terminal can determine that the state of the second pedal is a stepped state; when the opening value of the second pedal is smaller than or equal to the opening threshold value preset by the developer, the vehicle-mounted terminal can determine that the second pedal state is an un-depressed state. Illustratively, the opening threshold may be 0.

S302, if the first pedal state is a depressed state, the seat belt state on the driver side is an unbuckled state and the vehicle door state is an open state, switching the gear of the vehicle to a parking gear; or alternatively, the first and second heat exchangers may be,

In the present embodiment, when a brake pedal and/or an accelerator pedal of a vehicle fail, even if the driver releases the pedal, the opening value of the failed pedal may be larger than the opening threshold value. Therefore, in order to further improve the safety of the user when the vehicle-mounted terminal determines that the state of the seat belt on the driver side is the unbuckled state and the state of the door is the open state, if the vehicle-mounted terminal determines that the first pedal state or the second pedal state is the depressed state, the vehicle-mounted terminal can switch the gear of the vehicle to the parking gear and keep the vehicle power supply in the started state.

In this embodiment, because the brake pedal and/or the accelerator pedal of the vehicle fail, or the driver steps on the brake pedal and/or the accelerator pedal by mistake when preparing to get off the vehicle, or the opening sensor of the brake pedal and/or the accelerator pedal fails, the brake pedal or the accelerator pedal may be in a stepped state when preparing to get off the driving position, so that in order to further ensure the safety of the user when getting off the vehicle, the vehicle-mounted terminal may switch the gear of the vehicle to the parking gear, and keep the whole vehicle power supply in a starting state, so as to ensure that the vehicle is in a stable state when the user gets off the vehicle.

In one possible implementation, when the state of the seat belt on the driver side is an unbuckled state and the state of the door is an open state, if the in-vehicle terminal determines that the first pedal state or the second pedal state is a depressed state, the in-vehicle terminal may acquire the running speed of the vehicle. Specifically, the in-vehicle terminal may acquire the running speed of the vehicle through a wheel speed sensor or an electronic stability system on the vehicle.

After acquiring the running speed of the vehicle, the vehicle-mounted terminal can judge whether the current running speed of the vehicle is smaller than or equal to a speed threshold preset by a developer. Wherein the speed threshold may be greater than 0. If the vehicle-mounted terminal determines that the current running speed of the vehicle is less than or equal to the speed threshold, the vehicle-mounted terminal may shift the gear of the vehicle to a neutral gear (N-gear).

If the vehicle-mounted terminal judges that the current running speed of the vehicle is greater than the speed threshold, the vehicle-mounted terminal can maintain the current gear of the vehicle unchanged and generate fourth text prompt information and/or fourth voice prompt information. The vehicle-mounted terminal can display the fourth text prompt information through display equipment preset by a developer and/or play the fourth sound prompt information through sound equipment preset by the developer so as to inform a driver that a safety belt on the driver side is not tied and/or a vehicle door on the driver side is not closed.

In one possible implementation manner, the vehicle-mounted terminal may further determine whether the current running speed of the vehicle is 0 after determining that the first pedal state and/or the second pedal state is the depressed state. If the vehicle-mounted terminal determines that the current running speed of the vehicle is 0, the vehicle-mounted terminal can directly switch the gear of the vehicle to the parking gear. If the vehicle-mounted terminal determines that the current running speed of the vehicle is not 0, the vehicle-mounted terminal can switch the gear of the vehicle to the neutral gear. After the vehicle gear is switched to the neutral gear by the vehicle-mounted terminal, the duration of the neutral gear of the vehicle can be acquired through a timer preset by a developer. The vehicle-mounted terminal can continuously judge whether the acquired duration is greater than or equal to a time threshold preset by a developer. If the vehicle-mounted terminal judges that the currently acquired duration is greater than or equal to the time threshold, the vehicle-mounted terminal can switch the gear of the vehicle to the parking gear. The in-vehicle terminal may also activate a parking brake of the vehicle after switching to the parking gear to further stabilize the vehicle.

In one possible implementation, if the vehicle-mounted terminal determines that the duration currently acquired is less than the time threshold, the vehicle-mounted terminal will maintain the neutral gear unchanged and continue to acquire the duration of the neutral gear.

In this embodiment, when the vehicle-mounted terminal determines that the running speed of the vehicle is less than or equal to the speed threshold and is not 0, the vehicle-mounted terminal may first switch the vehicle gear to the neutral gear, and switch the vehicle gear to the park gear after the vehicle continues to be in the neutral gear for a period of time. The method provided by the embodiment can effectively avoid rollover events caused by the fact that the vehicle-mounted terminal directly switches the gear into the parking gear in the vehicle running state, and further improves the safety of the vehicle and the feasibility of automatic parking.

Referring to fig. 4, a schematic block diagram of an automatic parking control system according to an embodiment of the present application is shown. As shown in fig. 4, the automatic parking control system may include a gear calculating module, a state judging module, a parking activating module, and a display and speaker module. The gear calculation module may be configured to obtain gear information in a current state of the vehicle. When the gear calculation module determines that the currently acquired gear information is any other gear except the parking gear, the automatic parking control system can judge whether the driver is ready to leave the driving gear or not through the state judgment module, namely, whether the driver is in a pre-off state or not.

The state determination module may determine whether the driver is in a pre-unseated state based on a pedal state of the vehicle, a seat belt state on the driver side, and a door state on the driver side. However, when the state judgment module determines that the driver is in the pre-off state, the automatic parking control system can execute automatic parking operation through the parking activation module. The park activation module may shift a gear of the vehicle to a park gear and activate a park brake of the vehicle. After the automatic parking control system switches the gear into the parking gear and starts the parking brake, the corresponding text prompt information can be displayed and the corresponding sound prompt information can be played through the display of the speaker module.

In one possible implementation manner, after the vehicle-mounted terminal performs the automatic parking operation, if the driver needs to continue driving in the current state, the driver may initiate a gear control instruction to the vehicle-mounted terminal through a gear controller on the vehicle. The vehicle-mounted terminal can respond to a gear control instruction initiated by a driver to switch the gear of the vehicle to a target gear corresponding to the gear control instruction. The vehicle-mounted terminal can also respond to a gear control instruction initiated by a driver to generate first text prompt information and/or first voice prompt information. The vehicle-mounted terminal can display the first text prompt information through display equipment preset by a developer and/or play the first sound prompt information through sound equipment preset by the developer so as to inform a driver that the vehicle door is not closed and/or the safety belt is not tied.

In this embodiment, when the driver needs to continue traveling in the current state, the vehicle-mounted terminal may switch the gear of the vehicle to the target gear corresponding to the gear control instruction in response to the gear control instruction issued by the driver. By the method provided by the embodiment, when the driver needs to continue running in the pre-off state, the vehicle-mounted terminal can be switched to the corresponding target gear so as to allow the driver to continue running. Therefore, the method provided by the embodiment can improve the usability of the scheme, and the driving function of the vehicle is not affected while the safety of the driver is protected.

Fig. 5 shows a flowchart of a specific implementation of a control method S202 for a vehicle gear according to a third embodiment of the present application. Referring to fig. 5, compared to the embodiment of fig. 2, in the method for controlling a vehicle gear provided in this embodiment, S202 includes: s501 to S502 are specifically described below:

S501, acquiring a first pedal state of a brake pedal and a second pedal state of an accelerator pedal.

Since the content of S501 is the same as that of S301 in the second embodiment of the present application, the specific implementation please of S501 is referred to the second embodiment of the present application, and will not be described here again.

S502, if the driver-side seatbelt state is an unbuckled state, the door state is an open state, the first pedal state is an un-depressed state, and the second pedal state is an un-depressed state, the shift position of the vehicle is switched to the park position, and the vehicle is controlled to be powered down.

In this embodiment, when the state of the seat belt on the driver side is the unbuckled state and the state of the door on the driver side is the open state, if the vehicle-mounted terminal determines that the first pedal state of the vehicle is the un-depressed state and the second pedal state is the un-depressed state, the vehicle-mounted terminal may switch the gear of the vehicle to the parking gear and send a power-down instruction to the vehicle controller to control the power down of the vehicle.

In the present embodiment, since the in-vehicle terminal can determine that the driver is ready to leave the vehicle at this time when the first pedal state is the non-depressed state and the second pedal state is the non-depressed state, the in-vehicle terminal can switch the gear of the vehicle to the parking gear and control the vehicle to be powered down. By the method provided by the embodiment, the situation of sliding caused by the fact that the vehicle is in a power gear can be effectively avoided.

It should be noted that, the sequence number of each step in the above embodiment does not mean the sequence of execution sequence, and the execution sequence of each process should be determined by its function and internal logic, and should not limit the implementation process of the embodiment of the present application in any way.

Referring to fig. 6, a schematic diagram of a control device for a vehicle gear according to an embodiment of the present application may specifically include a state obtaining module 601 and a gear control module 602, where:
