Fig. 1 shows a block diagram of a door sound effect simulation apparatus 100 according to an embodiment of the present invention, and as can be seen from the figure, the door sound effect simulation system 100 includes a door actuator 101, a sensor 102, an on-board processor 103, and a speaker 104. Wherein, the sensor 102 is connected with the door actuator 101 in a communication way, the door actuator 101 is connected with the vehicle-mounted processor 103 in a communication way, and the vehicle-mounted processor 103 is connected with the loudspeaker 104 in a communication way.
In the embodiment of the present application, the sensor 102 is an original sensor of the vehicle, and more specifically, the sensor 102 is already assembled at the time of the vehicle shipment, and is not added to the original equipment of the vehicle. The sensor 102 is configured to collect a sensing signal of the vehicle door during opening or closing, and send the sensing signal to the vehicle door actuator 101. The door actuator 101 generates a position signal indicative of a real-time position of the door during opening or closing based on the sensor signal and sends the position signal to the onboard processor 103. The on-board processor 103 receives the position signal, generates a sound effect signal from the position signal, and outputs the sound effect signal in real time based on the speaker 104. Thus, based on the interaction among the door actuator 101, the sensor 102, the onboard processor 103 and the speaker 104, the real-time simulation of the door sound can be continuously realized in the opening or closing process of the door, and the acoustic performance of the door is improved. The interaction between the door actuator 101, the sensor 102, the onboard processor 103 and the speaker 104 will be described in detail below. In the embodiment of the application, the vehicle door is an electrically driven vehicle door and does not need to be opened or closed manually.
Fig. 2 shows a flowchart of a door sound effect simulation method according to an embodiment of the present invention, where the door sound effect simulation method is applied to the door sound effect simulation apparatus 100, and specifically includes the following steps:
and S21, receiving the sensing signal collected by the sensor by the vehicle door actuator in the opening or closing process of the vehicle door.
In this application embodiment, the vehicle can realize comparatively ripe car networking technology on 5G, marginal calculation and artificial intelligence's basis, for example, the user can pass through the opening or closing of door physics button, mobile terminal, wearing equipment or on-vehicle screen trigger door. Specifically, the vehicle door actuator 101 is configured to control opening or closing of a vehicle door, and the vehicle door actuator 101 may receive a trigger signal transmitted by a vehicle door physical key, a mobile terminal, a wearable device, or an on-board screen, and control opening or closing of the vehicle door according to the trigger signal.
It should be understood that the embodiments of the present application are interactions during the opening or closing of the vehicle door, and not at the instant of opening or closing of the vehicle door.
Specifically, the door opening process refers to: the door lock is unlocked, the door is gradually opened outwards from a closed state, and the door is stopped when the door is opened to a set angle (the door moves from a stationary state to a stationary state).
Specifically, the door closing process refers to: when the vehicle door is in an opened state, a set angle exists between the vehicle door and the vehicle body, the vehicle door is gradually close to the vehicle body from the opened state, the set angle is gradually reduced until the vehicle body is buckled with the vehicle door, and the vehicle door lock is locked (the vehicle door moves from a static state to a static state).
Further, the sensor 102 collects a sensing signal in real time during the opening or closing process of the vehicle door, wherein the sensing signal is a kind of original signal for reflecting the position of the vehicle door. In the implementation process, the types of the sensing signals can be many, and the embodiments of the present application exemplify two types of sensing signals, but of course, in the implementation process, the embodiments of the present application are not limited to the two types of sensing signals enumerated in the embodiments of the present application:
first-type sensing signals: for characterizing the real-time length value of the hydraulic lever during opening or closing of the vehicle door.
In this embodiment, the vehicle door actuator 101 further includes a hydraulic rod, where the hydraulic rod may be disposed at a living hinge of the vehicle door, it can be understood that when the vehicle door is opened or closed, there may be rotation (of a small vehicle) or movement (of seven or more vehicles), when the vehicle door is rotated or moved, the length of the hydraulic rod may be changed, and when the vehicle door is rotated or moved to different positions, the lengths of the hydraulic rods are different, so that a sensing signal acquired by the sensor 102 may be used to represent a real-time length value of the hydraulic rod during the opening or closing process of the vehicle door, and the real-time length value may reflect a real-time position where the vehicle door is located during the opening or closing process.
Second-type sensing signals: the method is used for representing the real-time potential difference value on the Hall semiconductor wafer in the opening or closing process of the vehicle door.
In this case, the sensor 102 is a hall sensor, wherein the hall sensor includes a hall semiconductor chip, based on the hall effect, the hall semiconductor chip has a variable potential difference during the opening or closing process of the vehicle door, and when the vehicle door rotates or moves to different positions, the potential difference existing on the hall semiconductor chip is different, so that the sensing signal collected by the sensor 102 can be used for representing the real-time potential difference value on the hall semiconductor chip during the opening or closing process of the vehicle door, and the real-time potential difference value can reflect the real-time position of the vehicle door during the opening or closing process.
In the embodiment of the present application, the sensor 102 may be disposed at the vehicle door, or may be disposed at other positions in the vehicle, as long as the acquisition of the sensing signal can be realized in the opening or closing process of the vehicle door.
For example, in the implementation, the sensor 102 may be disposed at a door, the sensor 102 may be disposed at the door actuator 101, and the sensor may be disposed at a center console position of the vehicle, and it should be understood that the above examples are not limited to the position of the sensor 102.
And S22, the vehicle door actuator generates a position signal according to the sensing signal and sends the position signal to the vehicle-mounted processor.
Specifically, the door actuator 101 may generate the position signal in two ways:
1) the sensing signals are of a first type.
The vehicle door execution mechanism 101 obtains a real-time length value according to the sensing signal, determines a real-time position where the vehicle door is located in the opening or closing process according to the real-time length value, and generates a position signal according to the real-time position.
For example, taking the closing process of the vehicle door as an example, when the vehicle door is changed from the open state to the closed state, the length of the hydraulic rod is gradually reduced, and for example, when the vehicle door is in the fully open state, the length of the hydraulic rod is LmaxWhen the vehicle door is in a closed state, the length of the hydraulic rod is Lmin. As another example, the real-time length value may be LtWherein L ismin≤Lt≤Lmin. Wherein, can be according to LtA real-time position at which the door is in the process of closing is determined.
For another example, the sensing signal may be a digital signal, such as a binary digital signal, which is received by the door actuator 101 and then analyzed by the door actuator 101 to obtain LtAnd determining L according to the linear relation between the real-time length value and the position of the vehicle doortThe corresponding (car door) real-time position, and the determined real-time position can also be a digital signal.
Further, the door actuator 101 generates a position signal from the real-time position and sends the position signal to the onboard processor 103.
2) The sensing signals are second type sensing signals.
The vehicle door actuating mechanism 101 obtains a real-time potential difference value according to the sensing signal, determines a real-time position where the vehicle door is located in the opening or closing process according to the real-time potential difference value, and generates a position signal according to the real-time position.
For example, taking the closing process of the vehicle door as an example, when the vehicle door is changed from the open state to the closed state, the potential difference across the hall semiconductor chip is gradually decreased or gradually increased, and for example, when the vehicle door is in the fully open state, the potential difference is U1When the door is closed, the potential difference is U2. As yet another example of an implementation of the method,real-time potential difference value UtWherein, U1≤Ut≤U2Or U2≤Ut≤U1. Wherein, can be according to UtA real-time position at which the door is in the process of closing is determined.
For another example, the sensing signal may be a digital signal, such as a binary digital signal, which is received by the door actuator 101 and then analyzed by the door actuator 101 to obtain UtAnd determining U according to the linear relation between the real-time potential difference value and the position of the vehicle doortThe corresponding (car door) real-time position, and the determined real-time position can also be a digital signal.
Further, the door actuator 101 generates a position signal from the real-time position and sends the position signal to the onboard processor 103.
And S23, the vehicle-mounted processor receives the position signal, generates a sound effect signal according to the position signal and outputs the sound effect signal in real time.
It can be understood that the position signal is used for representing the real-time position of the vehicle door in the opening or closing process, and after the vehicle-mounted processor 103 receives the position signal, the position signal can be analyzed, so that the real-time position of the vehicle door is determined, then the sound effect signal is generated according to the real-time position of the vehicle door, and the sound effect signal is output in real time. The sound effect signal is a simulated sound of the vehicle door during opening or closing, and more specifically, the sound effect signal is not a sound actually generated by the vehicle door during opening or closing.
Specifically, the onboard processor 103 receives the position signal, generates an audio signal according to the position signal, and then processes the audio signal according to the set sound effect mode to obtain the sound effect signal.
In the embodiment of the present application, the setting of the sound effect mode is performed by the on-board processor 103 according to a user operation, for example, the user selects the sound effect mode through a mobile phone, a wearable device, or an on-board screen, and the on-board processor 103 receives a sound effect mode selection instruction sent by the mobile phone, the wearable device, or the on-board screen, and sets the setting of the sound effect mode according to the sound effect mode selection instruction. For example, the set sound effect mode may be a sound effect generated by a wooden door panel during opening or closing, or a sound effect generated by a cabin door during opening or closing. Therefore, various optional car door acoustic special effects can be provided for a user, sound effect updating in the later period is supported, the acoustic performance of the car door is effectively improved, the interactivity of the car is improved, and the user experience and the added value of products are enhanced.
Further, the on-board processor 103 outputs the sound effect signal to the speaker 104 in real time, so that the speaker 104 amplifies the sound effect signal, and then plays the amplified sound effect signal in real time, thereby realizing sound simulation of the vehicle door in the opening or closing process, and thus continuously realizing real-time simulation of the vehicle door sound in the opening or closing process of the vehicle door, and improving the acoustic performance of the vehicle door in the using process.
In the embodiment of the present application, the speaker 104 may be disposed at the door, or may be disposed at other positions in the vehicle, as long as the method and the real-time output of the sound effect signal can be realized during the opening or closing process of the door.
For example, in an implementation, the speaker 104 may be disposed at a vehicle door, and the speaker 104 may be disposed at a seat, and it should be understood that the above examples are not limiting on the location of the speaker 104.
It will be appreciated that the acoustic effect signal may be blended with noise actually generated by the door during opening or closing to improve the acoustic performance of the door. The noise that the door actually produced in opening or closing process receives the motor, the influence of factors such as body structure material, more specifically, the noise is difficult to eliminate completely to a certain extent, the mode of noise needs to increase extra equipment to the common reverse sound wave of adoption counteracts the noise, the manufacturing cost of vehicle has been improved, and adopt the door sound effect simulation method that the embodiment of this application provided, not only can improve the door acoustic performance of vehicle, can also carry out effectual integration with the noise that the door actually produced in opening or closing process, need not to increase extra equipment, also need not to improve the original body structure of vehicle, not only can realize the noise treatment, can also improve the door acoustic performance in opening or closing process, the cost of noise treatment has effectively been reduced.
In addition, because the sound effect signal is generated according to the set sound effect mode, the on-board processor 103 can switch the set sound effect mode, and the interactivity of the vehicle is further improved.
It should be understood that the sound effect simulation method for the vehicle door provided by the embodiment of the application is to perform continuous sound effect simulation on the whole process of opening or closing the vehicle door, so that the acoustic performance of the vehicle door can be improved, and the sound effect signal can be improved and optimized, so that the vehicle door has simulation sound with high recognition degree in the whole process of opening or closing, and data basis is provided for optimization of the acoustic performance of the vehicle. For example, before the on-board processor 103 sends the sound effect signal to the speaker 104, the sound effect signal may be optimized without changing the sound spectrum composition of the sound effect signal, specifically referring to fig. 3, fig. 3 shows a sound effect simulation diagram during the opening process of the vehicle door, where the abscissa is frequency and the unit is Hz, and the ordinate is decibel of sound and the unit is db (a).
As can be seen from fig. 3, the frequency spectrum signal a close to the abscissa axis is the sound effect signal after optimization, the frequency spectrum signal B located above the sound effect signal after optimization is the sound effect signal before optimization, and when the vehicle door is just opened, the decibel of the frequency spectrum signal a is higher than that of the frequency spectrum signal B, so that the sound simulation when the vehicle door is just opened can be enhanced, thereby realizing the optimization of the sound effect signal and further improving the acoustic performance of the vehicle door.
The embodiment of the present invention further provides a car door sound effect simulation apparatus 100, which includes a memory, a processor, and a computer program stored in the memory and executable on the processor, and when the processor executes the computer program, the car door sound effect simulation method is implemented.
An embodiment of the present invention also provides a computer-readable storage medium, which includes a computer program. The computer program controls the door sound effect simulation apparatus 100 in which the readable storage medium is located to execute the door sound effect simulation method described above when running.
On the basis, an embodiment of the present invention further provides a car door sound effect simulation method, which is applied to the vehicle-mounted processor 103, and the method includes:
in the opening or closing process of the vehicle door, the vehicle-mounted processor receives a position signal sent by a vehicle door actuating mechanism; the position signal is used for representing the real-time position of the vehicle door in the opening or closing process, the position signal is generated by the vehicle door actuating mechanism according to the received sensing signal, and the sensing signal is acquired by the sensor in the opening or closing process of the vehicle door.

On the basis of the above, as shown in fig. 4, an embodiment of the present invention provides a block diagram of modules of an on-board processor 103, where the on-board processor 103 includes: a location signal receiving module 1031, and a sound effect signal output module 1032.
