For the convenience of understanding, the voice control method of the steering wheel of the vehicle will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart illustrating a voice control method for a steering wheel of a vehicle according to an embodiment of the present invention.
The method comprises the following steps:
s1, receiving a voice instruction to be recognized;
in the embodiment of the invention, in order to realize the interaction between a person and a steering wheel, electronic equipment (hereinafter referred to as the electronic equipment) for executing the method can be installed in the steering wheel of the passenger car. The voice command to be recognized is a rotation command sent by the driver to the electronic device through voice, and in practical application, the rotation command may be a left rotation angle of 500 degrees, a right rotation angle of 600 degrees, a rotation angular speed of 100 degrees per second, and the like, and is not limited specifically.
And S2, recognizing the voice command to be recognized and generating an operation command.
In the embodiment of the invention, in order to realize better interaction between a person and a vehicle, after a voice instruction to be recognized sent by a driver is received, the voice instruction to be recognized is recognized firstly, and then an operation instruction is generated based on a recognition result of the voice instruction to be recognized, wherein the operation instruction is a command for controlling the motor to operate, such as controlling the motor to rotate forwards and backwards and the like, and is not limited specifically.
As to the specific process of recognizing the voice command to be recognized, detailed description will be given later, and will not be repeated here.
And S3, sending the operation instruction to a motor so that the motor controls the steering wheel based on the operation instruction.
In the embodiment of the invention, in order to control the rotation of the motor, the motor is communicated and sends an operation instruction to the motor, and the motor controls the rotation of the steering wheel of the passenger car according to the operation instruction after receiving the operation instruction.
In practical application, the rotating direction and the current magnitude of the motor can be controlled through PID, so that the passenger car steering wheel reaches a target steering angle and a target steering angle speed.
In the embodiment of the invention, the voice instruction is received, recognized and generated, and then sent to the motor, and the motor controls the steering wheel to rotate according to the operation instruction; the rotation of the steering wheel can be controlled through voice commands without manual operation of a driver, so that the workload of the driver is reduced, and intelligent steering is realized.
Fig. 2 shows another voice control method of a steering wheel of a vehicle. As shown in figure 2 of the drawings, in which,
in the embodiment of the invention, the passenger car steering wheel has two working modes, namely a manual control mode and a voice control mode. In actual work, a liquid crystal display screen can be arranged on a steering wheel of a passenger car, and a driver can select a manual control mode or a voice control mode through the touch of the liquid crystal display screen to switch the manual control mode and the voice control mode; or the driver directly rotates the steering wheel by hand, and the voice control mode can be automatically exited and switched to the manual control mode.
In practical application, the liquid crystal display screen can also display the rotation condition of the steering wheel and whether the steering wheel is in a zero position, so that a driver can conveniently check the steering wheel at any time.
When a passenger car is started, the working mode of the steering wheel is the manual control mode by default; in the manual control mode, the motor can not control the rotation of the steering wheel of the passenger car through a voice command, the motor manually shifts the steering wheel to assist with the speed, and meanwhile, a corner sensor and a rotating speed sensor in the steering system feed back the actual corner and the actual corner speed of the steering wheel detected in real time to the electronic equipment and display the actual corner and the actual corner speed on a liquid crystal display screen in real time; the target steering angle and the target steering angle speed of the steering wheel may be displayed on the liquid crystal display at the same time.
After the passenger car is started, a driver can select a voice control mode through touch operation of the liquid crystal display screen, and at the moment, the voice control mode is activated. In practical application, when a voice command to be recognized is received, whether the voice command to be recognized is sent by a driver or not is judged firstly; then, in some possible embodiments, the method further comprises:
judging whether the voice command to be recognized is sent by a driver;
if yes, executing the steps of recognizing the voice command to be recognized and generating an operation command;
if not, the flow ends.
It can be understood that whether the voice command to be recognized is sent by the driver or not can prevent people except the driver from sending the voice command to be recognized to the electronic equipment, and driving safety is ensured. In practical application, any method may be adopted to determine whether the voice command to be recognized is sent by the driver, for example, performing voiceprint comparison on the voice command to be recognized, and the like, which is not limited specifically. Then, in some possible embodiments, determining whether the voice command to be recognized is issued by the driver includes:
extracting the voiceprint features to be recognized of the voice command to be recognized;
matching the voiceprint features to be identified with preset voiceprint features in a prestored voiceprint library;
if the preset voiceprint features matched with the voiceprint features to be recognized exist in the voiceprint library, judging that the voice command to be recognized is sent by a driver, executing the step of recognizing the voice command to be recognized and generating an operation command;
and if the preset voiceprint characteristics matched with the voiceprint characteristics to be recognized do not exist in the voiceprint library, judging that the voice command to be recognized is not sent out by the driver, and ending the process.
In order to judge whether the voice command to be recognized is sent by the driver, a voiceprint library containing voiceprint characteristics of all drivers of the passenger car can be stored in the electronic equipment in advance. And after receiving the voice command to be recognized, matching the voiceprint characteristics of the voice command to be recognized with the voiceprint characteristics stored in the voiceprint library. The voiceprint refers to a sound wave spectrum which carries speech information and is displayed by an electro-acoustic instrument, and the voiceprint characteristics comprise characteristics such as tone color, tone length, tone intensity and tone pitch. In order to facilitate the distinguishing description, the voiceprint features of the semantic instruction to be recognized are defined as the voiceprint features to be recognized, and the voiceprint features in the voiceprint library are defined as the preset voiceprint features.
The corresponding relation between the preset voiceprint features and the drivers exists in the voiceprint library, namely, the corresponding voiceprint features can be found out in the voiceprint library by the voices of all the drivers of the passenger car. In practical application, a voiceprint library can be established by adopting a mode of training a neural network model. Pre-extracting voiceprint characteristics of all drivers of the passenger car as training data, and training a neural network by taking the drivers corresponding to all the voiceprint characteristics as training labels to obtain a voiceprint characteristic model; and pre-extracting the voiceprint characteristics of all drivers of the passenger car, namely the preset voiceprint characteristics. And after receiving the voice command to be recognized, extracting the voiceprint features to be recognized of the voice command to be recognized, inputting the voiceprint features to be recognized into the voiceprint feature model, and outputting a driver corresponding to the voiceprint features to be recognized if the voiceprint features to be recognized can be successfully matched with the preset voiceprint features.
In order to judge whether the voiceprint features to be recognized are the voiceprint features of the passenger car driver, matching the voiceprint features to be recognized with preset voiceprint features in a voiceprint library; if the voiceprint features to be recognized can be successfully matched with the preset voiceprint features, the voiceprint features to be recognized are judged to be the voiceprint features of the driver, the voice command to be recognized is sent out by the driver, the driver can be determined to send out the voice command to be recognized according to the corresponding relation between the preset voiceprint features and the driver, the voice command to be recognized can be recognized, and the step of generating the operation command can be executed. And if the voiceprint features to be recognized cannot be successfully matched with the preset voiceprint features in the voiceprint library, judging that the voiceprint features to be recognized are not the voiceprint features of the passenger car driver, if the voice command to be recognized is not sent by the driver, not executing the step of recognizing the voice command to be recognized and generating an operation command, and ending the process.
It can be understood that whether the voice command to be recognized is sent by the passenger car driver can be judged based on the comparison between the voiceprint feature to be recognized and the preset voiceprint feature in the voiceprint library, so that a person except the driver is prevented from sending the voice command to be recognized to the electronic device according to the intention, and the driving safety is ensured. In practical application, after the voice command to be recognized is confirmed to be sent by a passenger car driver, the voice command to be recognized needs to be further recognized; then, in some possible embodiments, recognizing the voice instruction to be recognized and generating an operation instruction includes:
recognizing the voice command to be recognized and generating text information corresponding to the voice command to be recognized;
and generating an operation instruction according to the text information.
In order to further execute the voice command to be recognized, the voice command to be recognized needs to be recognized, text information corresponding to the voice command to be recognized is generated, and then an operation command is generated according to the text information. The operation command is a command for controlling the operation of the motor, such as controlling the motor to rotate forward, rotate backward, and the like, and is not limited in particular.
It can be understood that the voice command to be recognized is recognized to generate the text information corresponding to the voice command, and the operation command is generated according to the text information, so that the voice command to be recognized can be converted into the operation command for the motor, and the control of the steering wheel by the voice command is realized. In practical application, the voice command to be recognized can be recognized in any mode, and text information corresponding to the voice command can be generated; then, in some possible embodiments, recognizing the voice command to be recognized, and generating text information corresponding to the voice command to be recognized includes:
identifying a feature vector to be identified contained in the voice command to be identified;
matching the feature vector to be identified with a preset feature vector in a pre-stored feature library;
and generating text information corresponding to the voice instruction to be recognized based on the matching result.
In order to recognize the voice command to be recognized, the feature vector included in the voice command to be recognized may be recognized first, and a semantic library including the feature vector may be stored in advance in the electronic device for the purpose of recognizing the feature vector included in the voice command to be recognized. In practical applications, the feature vector may include isolated words, connected words, keywords, and the like, and is not limited specifically. For the convenience of description differentiation, the feature vector included in the speech instruction to be recognized is defined as the feature vector to be recognized, and the feature vector included in the semantic library is defined as the preset feature vector.
In practical application, in order to improve the probability of correct recognition, for the same feature to be recognized, a plurality of preset feature vectors containing keywords can be set in a feature library, and the language features of different languages or different dialects are considered at the same time. For example, the left turn angle of the steering wheel may be set by using a plurality of preset feature vectors, such as "left turn XXX/right turn XXX/left turn XXX … …", without limitation.
The corresponding relation between the preset feature vector and the text information exists in the feature library, and in practical application, the feature library can be established in a mode of training a neural network model; pre-extracting feature vectors as training data, and training a neural network by taking text information respectively corresponding to all the feature vectors as training labels to obtain a feature model; the pre-extracted feature vector is the preset feature vector. When the feature vector to be recognized is input into the feature model, the preset feature vector with the highest similarity to the feature vector to be recognized can be determined, and then the text information corresponding to the preset feature vector is output.
In order to generate text information corresponding to the voice command to be recognized, matching a feature vector to be recognized contained in the voice command to be recognized with a preset feature vector in a semantic library; and obtaining a preset feature vector corresponding to the feature vector to be recognized according to the matching result, and obtaining text information corresponding to the voice command to be recognized based on the corresponding relation between the preset feature vector and the text information in the feature library.
It can be understood that the accurate operation instruction is favorably generated by recognizing the voice instruction to be recognized and obtaining the text information corresponding to the voice instruction to be recognized. In practical applications, the voice command to be recognized may include various desired operations on the steering wheel, such as, for example, turning left 300 °, turning right 400 °, turning angular velocity of 300 degrees per second, and the like, and is not limited specifically. Then, in some possible embodiments, the text information includes a target corner and a target corner speed;
generating an operation instruction according to the text information, wherein the operation instruction comprises the following steps:
receiving an actual corner and an actual corner speed;
performing difference operation on the target corner and the actual corner to obtain a corner difference value, and performing difference operation on the target corner speed and the actual corner speed to obtain a corner speed difference value;
and generating an operation instruction based on the turning angle difference value and the turning angle speed difference value.
In order to generate an operation instruction according to the target corner and the target corner speed, based on the received actual target corner and the target corner speed, performing difference operation on the target corner and the actual corner to obtain a corner difference value, and performing difference operation on the target corner speed and the actual corner speed to obtain a corner speed difference value; and generating an operation instruction according to the rotation angle difference and the rotation angle speed difference, wherein the operation instruction comprises the rotation angle difference and the rotation angle speed difference, and the motor rotates according to the rotation angle difference and the rotation angle speed difference so as to drive the steering wheel to rotate.
In practical application, the rotatable angle range of the steering wheel of the passenger car is [ -1000 °, +1000 ° ], namely the target rotation angle range can be [ -1000 °, +1000 ° ], and the angle value is negative and indicates that the steering wheel is turned left; the angle value is positive, indicating that the steering wheel is turned right. The steering wheel rotational angular velocity may range from 0/s, 500/s, i.e., the greater the target angular velocity range may be from 0/s, 500/s, indicating faster steering wheel rotation.
The method has the advantages that the target corner and the actual corner are subjected to difference operation, the target corner speed and the actual corner speed are subjected to difference operation, and the operation instruction is generated based on the corner difference and the corner speed difference, so that the motor can rotate more accurately, and the passenger car steering wheel is driven to reach the target corner and the target corner speed.
After receiving the operation instruction, the motor rotates according to the operation instruction, so that the steering wheel is driven to rotate; when the actual turning angle of the steering wheel reaches the target turning angle and the actual turning speed of the steering wheel reaches the target turning speed, stopping the rotation of the motor; and if the actual turning angle of the steering wheel does not reach the target turning angle or the actual turning speed of the steering wheel does not reach the target turning speed, the motor continues to rotate to drive the steering wheel to rotate until the steering wheel reaches the target rotating part and the target turning speed, and the motor stops rotating.
Fig. 3 shows a diagram of a hardware architecture, and fig. 4 shows an operation principle of the hardware architecture of fig. 3.

At a low speed, the electro-hydraulic power-assisted steering system can provide large steering power, so that the steering portability of the vehicle is guaranteed; when the speed of a vehicle is improved, the steering power provided by the electro-hydraulic power-assisted steering system is gradually reduced, the steering force required by a driver is gradually increased during steering, and the stability of the vehicle is improved.
The electric power steering system can apply certain additional aligning torque or damping torque, so that the steering wheel can accurately return to the middle position at low speed, the oscillation and the overshoot of the steering wheel in the high-speed aligning process can be inhibited, and the aligning performance of the vehicle at high and low speeds is considered.
