Description

Technical Field

[0001] This application relates to the field of vehicle shift control technology, and in particular to an electronic shift control method, device, electronic equipment and storage medium. Background Technology

[0002] With the development of electrification, more and more mechanical structures in automobiles are being replaced by electronic structures, and the electronic shift unit is one of them. The function of the electronic shift unit is to transmit the user's control of the vehicle's forward, reverse, and parking shift operations to the vehicle control unit. After performing logical judgments, the vehicle control unit controls the motor to perform the corresponding operating actions. At the same time, the vehicle control unit transmits the motor's operating status to the electronic shift unit, which involves communication issues between the electronic shift unit and the vehicle control unit.

[0003] Currently, the pins of the electronic shift unit are usually connected to the pins of the vehicle control unit via three wire harnesses to transmit reverse, neutral, and forward gear information. When the electronic shift unit sets the reverse, neutral, and forward gear pins to a high level, it means the gear is valid; when it sets them to a low level, it means the gear is invalid. The actual vehicle gear position is transmitted from the vehicle control unit to the electronic shift unit via the CAN network.

[0004] However, when changing the vehicle's gear position via three wiring harnesses and CAN network communication, the three wiring harnesses occupy three pins of the electronic shift unit, resulting in a waste of pin resources. At the same time, when the vehicle control unit transmits the actual vehicle gear position to the electronic shift unit, the complex communication logic and physical structure of the CAN network, which requires corresponding functional programming and network management development based on the vehicle's communication architecture, leads to poor anti-interference capability and instability of the electrical signal corresponding to the actual vehicle gear position. Summary of the Invention

[0012] The vehicle control unit responds to the forced control signal to obtain the user request duration, wherein the user request duration is the cumulative generation duration corresponding to the forced control signal generated by the electronic shift unit when the user actively changes the vehicle's gear position only through the electronic shift unit within a preset time. The vehicle control unit determines the forced gear position information based on the user request duration, the preset request duration, and the level encoding table. The vehicle control unit obtains the forced operation gear based on the forced gear position information and the second motor operation information, wherein the second motor operation information represents the operating state of the vehicle motor after the vehicle control unit responds to the forced gear position information.

The vehicle control unit converts the vehicle operating gear into first pulse width modulation duty cycle information. The electronic shift unit parses the first pulse width modulation duty cycle information to obtain the vehicle operating gear. By using the level signals corresponding to two wire harnesses to form a combined level value, and then determining the level control signal, the problem of wasted pin resources caused by three wire harnesses occupying three pins of the electronic shift unit is solved. Furthermore, by establishing the correspondence between the first pulse width modulation duty cycle and the vehicle's operating gear, the vehicle control unit can transmit the actual vehicle operating gear to the electronic shift unit. This solves the problem of poor anti-interference capability and instability of electrical signals when transmitting the electrical signals corresponding to the actual vehicle operating gear, which is caused by the complexity of the communication logic and physical structure of CAN network communication and the need for corresponding functional programming and network management development based on the vehicle communication architecture.

[0041] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0043] The technical solution of this application involves the collection, storage, use, processing, transmission, provision and disclosure of user personal information and data, which comply with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0044] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals are provided for users to choose to authorize or refuse.

[0045] Figure 1 This diagram illustrates an application scenario of the electronic shift control method provided in this application. The electronic shift control method provided in this application can be applied to scenarios where a user shifts gears in a vehicle. For example, as shown... Figure 1 As shown, the execution subject of the method provided in this application embodiment can be a vehicle-mounted device or an electronic control unit. Taking the electronic control unit as an example, the electronic control unit includes an electronic shift unit and a vehicle control unit. The electronic shift unit responds to the user's shift operation and generates a corresponding vehicle shift command. Then, according to the corresponding vehicle shift command, the vehicle control unit changes the operating state of the vehicle motor to realize the vehicle's gear shift. After the vehicle completes the gear shift, the electronic shift unit obtains the actual vehicle operating gear from the vehicle control unit. If the actual vehicle operating gear is consistent with the gear corresponding to the user's shift operation, the vehicle operates according to the actual vehicle operating gear. If the actual vehicle operating gear is inconsistent with the gear corresponding to the user's shift operation, the user is prompted that the vehicle has not shifted successfully, and the vehicle operates according to the actual vehicle operating gear.

[0046] Currently, the pins of the electronic shift unit are typically connected to the pins of the vehicle control unit via three wire harnesses to transmit reverse, neutral, and forward gear information. When the electronic shift unit sets the reverse, neutral, or forward gear pins to a high level, it indicates that the gear is active; when it sets them to a low level, it indicates that the gear is inactive. The actual vehicle gear position is then transmitted from the vehicle control unit to the electronic shift unit via the CAN network.

[0047] However, when changing the vehicle's gear position via three wiring harnesses and CAN network communication, the three wiring harnesses occupy three pins of the electronic shift unit, resulting in a waste of pin resources. At the same time, when the vehicle control unit transmits the actual vehicle gear position to the electronic shift unit, the complex communication logic and physical structure of the CAN network, which requires corresponding functional programming and network management development based on the vehicle's communication architecture, leads to poor anti-interference capability and instability of the electrical signal corresponding to the actual vehicle gear position.

[0048] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0049] Figure 2 A flowchart of an electronic shift control method provided in one embodiment of this application is shown below. Figure 2 As shown, the execution subject of the electronic shift control method provided in this embodiment can be a vehicle-mounted device or an electronic control unit. For example, this embodiment uses a vehicle-mounted device as the execution subject for explanation. The method provided in this application embodiment is applied to an electronic shift system, which includes an electronic shift unit and a vehicle control unit. The electronic shift control method provided in this embodiment includes the following steps:

[0050] Step S101: In response to the first user's gear shifting operation, a level control signal is generated through the electronic gear shifting unit. The level control signal includes a first level value and a second level value. The combined level value formed by the first level value and the second level value is used to characterize the target electronic gear corresponding to the first user's gear shifting operation.

[0051] For example, in communication coding, the target electronic gear position of the vehicle is defined by the coordination of high and low levels corresponding to two wire harnesses. That is, the first level value corresponding to the first wire harness and the second level value corresponding to the second wire harness are combined to form a combined level value, thereby obtaining four level value combinations. These four level value combinations can correspond to the four electronic gear positions of the vehicle. In response to the first user's gear shifting operation, the electronic gear shifting unit generates the corresponding level control signal, that is, obtains the target electronic gear position corresponding to the first user's gear shifting operation. More specifically, for example, Table 1 is a schematic table showing the correspondence between target electronic gear positions and combined level values. As shown in Table 1, "0" represents the low level of the wiring harness, and "1" represents the high level of the wiring harness. The physical forms of the vehicle's electronic shift unit include button type, knob type, column shifter type, and lever type. In this embodiment, the button type electronic shift unit is used as an example. The first user shift operation is that the user presses the "brake pedal" and presses the corresponding gear position of the "electronic shift unit" at the same time. Then, in response to the first user shift operation, the electronic shift unit generates a combined level value, that is, generates the corresponding level control signal. For example, when the user presses the "brake pedal" and presses the "reverse gear" corresponding to the "electronic shift unit", the electronic shift unit sets the voltage of the pin connected to the first wiring harness to a low level and sets the voltage of the pin connected to the second wiring harness to a high level. That is, the first level value corresponding to the first wiring harness is "0" and the second level value corresponding to the second wiring harness is "1". Thus, the level control signal generated by the electronic shift unit is "0,1".

[0052] Table 1

[0053]

[0054] Step S102: Obtain the level control signal through the vehicle control unit, and obtain the user-requested gear information according to the preset level encoding table. The level encoding table is used to characterize the mapping relationship between the combined level value and the electronic gear. The user-requested gear information is used to drive the vehicle control unit to electronically switch the vehicle motor.

[0055] For example, the level encoding table is used to characterize the mapping relationship between combined level values ​​and electronic gear positions. The user-requested gear position information is used to drive the vehicle control unit to electronically switch the vehicle motor. That is, by parsing and processing the acquired level control signal according to the level encoding table, the vehicle control unit can obtain the target electronic gear position corresponding to the first user's gear shift operation, which is the user-requested gear position information. Then, the vehicle control unit can be driven to electronically switch the vehicle motor based on the user-requested gear position information. More specifically, for example, Table 1 is the level encoding table. As shown in Table 1, "0" represents the low level of the wiring harness, and "1" represents the high level of the wiring harness. By parsing and processing the acquired level control signal according to the level encoding table, the vehicle control unit can obtain the user-requested electronic gear position, i.e., the user-requested gear position information.

[0056] In one possible implementation, the electronic shift unit is connected to the vehicle control unit via two wiring harnesses (a first wiring harness and a second wiring harness) to transmit level control signals. For example, in response to a first user's shift operation, the electronic shift unit generates a level control signal "0,1". Then, on the vehicle control unit side, the voltage of the pin connected to the first wiring harness is set to a low level, and the voltage of the pin connected to the second wiring harness is set to a high level, i.e., the first level value corresponding to the first wiring harness is "0", and the second level value corresponding to the second wiring harness is "1". The vehicle control unit then obtains the level control signal "0,1", and according to the level encoding table, determines that the electronic gear requested by the user is "reverse gear", i.e., obtains the user-requested gear information.

[0057] Step S103: The vehicle control unit determines the vehicle's operating gear based on the gear information requested by the user and the first motor's operating information. The first motor's operating information represents the operating status of the vehicle motor after the vehicle control unit responds to the gear information requested by the user.

[0058] For example, the first motor operation information represents the operating state of the vehicle motor after the vehicle control unit responds to the user's request for gear information. That is, the vehicle control unit is driven to electronically switch the vehicle motor according to the user's request for gear information, and then the vehicle control unit obtains the operating state of the vehicle motor, that is, the first motor operation information is obtained; then, by parsing the first motor operation information, the vehicle operating gear can be determined. In one possible implementation, if the vehicle's current operating gear is "Drive", the user's requested gear information is determined to be "Reverse" based on the level control signal "0,1". If the vehicle control unit is driven to switch the electronic gear of the vehicle motor to "Reverse" based on the "Reverse" gear, the vehicle motor's operating state is "Reverse", thus obtaining the first motor operating information info_1. The vehicle control unit then parses the first motor operating information info_1 corresponding to the "Reverse" state to determine that the vehicle's operating gear is "Reverse". If the vehicle control unit is driven to not switch the electronic gear of the vehicle motor to "Reverse" based on the "Reverse" gear, the vehicle motor's operating state remains "Forward", thus obtaining the first motor operating information info_2. The vehicle control unit then parses the first motor operating information info_2 corresponding to the "Forward" state to determine that the vehicle's operating gear is still "Drive".

[0059] Step S104: The vehicle operating gear is converted into the first pulse width modulation duty cycle information through the vehicle control unit.

[0060] For example, pulse width modulation (PWM) duty cycle information is used to indicate the state of a level signal, which includes a high-level state and a low-level state. The PWM duty cycle indicates the ratio of the duration of the high-level state to the duration of the complete data cycle. That is, the PWM duty cycle information includes the duty cycle value corresponding to the PWM duty cycle, as well as the duration of the high-level state, the duration of the low-level state, and the duration of the complete data cycle. By defining the correspondence between the PWM duty cycle and the vehicle's operating gear, the vehicle control unit can convert the vehicle's operating gear into PWM duty cycle information based on the predefined correspondence between the first PWM duty cycle and the vehicle's operating gear. More specifically, the vehicle operating gears include at least a first operating gear and a second operating gear; converting the vehicle operating gears into first pulse width modulation duty cycle information through the vehicle control unit includes: obtaining first gear duty cycle information based on the first operating gear through the vehicle control unit; or, obtaining second gear duty cycle information based on the second operating gear through the vehicle control unit; and obtaining first pulse width modulation duty cycle information based on the first gear duty cycle information or the second gear duty cycle information.

[0061] In one possible implementation, Table 2 is a schematic diagram of the correspondence between the first pulse width modulation duty cycle and the vehicle operating gear. As shown in Table 2, the vehicle operating gears include no request, reverse gear, neutral gear, drive gear, and low gear. According to the correspondence between the first pulse width modulation duty cycle and the vehicle operating gear, if the vehicle operating gear is "reverse gear", the first pulse width modulation duty cycle is obtained by the vehicle control unit when it is between 10% ≤ X < 30%, which is the first pulse width modulation duty cycle information. Here, X is the specific value of the first pulse width modulation duty cycle generated by the vehicle control unit based on the vehicle operating gear.

[0062] Table 2

[0063] First pulse width modulation duty cycle vehicle gear 0≤X<10％ No request 10％≤X<30％ Reverse gear 30％≤X<50％ gap 50％≤X<70％ forward gear 70％≤X<100％ low gear

[0064] Step S105: The first pulse width modulation duty cycle information is analyzed by the electronic shift unit to obtain the vehicle's operating gear.

[0065] For example, based on the correspondence between the first pulse width modulation (PWM) duty cycle and the vehicle's operating gear as shown in Table 2, the vehicle's operating gear can be determined by analyzing the PWM duty cycle information through the electronic shift unit. More specifically, for example, the first PWM duty cycle information is determined based on the numerical range of the PWM duty cycle as determined by the vehicle control unit. Then, the first PWM duty cycle information is analyzed by the electronic shift unit. That is, based on the correspondence between the first PWM duty cycle and the vehicle's operating gear as shown in Table 2, the vehicle's operating gear is obtained by the electronic shift unit according to the numerical range of the PWM duty cycle. For example, if the PWM duty cycle is between 10% ≤ X < 30%, the vehicle's operating gear is determined to be "reverse gear".

[0066] Furthermore, if the user presses the "forward" gear corresponding to the "electronic shift unit" at the same time as pressing the "brake pedal", the electronic shift unit will transmit the corresponding level control signal "1,1" to the vehicle control unit. The vehicle control unit will then electronically switch the vehicle motor according to the user's requested gear information determined by the level control signal "1,1". Subsequently, the actual operating state of the vehicle motor can be obtained through the vehicle control unit. That is, if the value range of the first pulse width modulation duty cycle determined by the vehicle control unit is 10%≤X<30%, then the vehicle's operating gear is "reverse", and the vehicle will operate according to the actual vehicle operating gear "reverse".

[0067] In this embodiment, the electronic shift control method is applied to an electronic shift system, which includes an electronic shift unit and a vehicle control unit. In response to a first user's shift operation, the electronic shift unit generates a level control signal, which includes a first level value and a second level value. The combined level value formed by the first and second level values ​​characterizes the target electronic gear corresponding to the first user's shift operation. The vehicle control unit acquires the level control signal and obtains the user-requested gear information according to a preset level encoding table. The level encoding table characterizes the mapping relationship between the combined level value and the electronic gear. The user-requested gear information drives the vehicle control unit to electronically switch the vehicle motor. The vehicle control unit determines the vehicle's operating gear based on the user-requested gear information and the first motor's operating information. The first motor's operating information characterizes the vehicle motor's operating state after the vehicle control unit responds to the user-requested gear information. The vehicle control unit converts the vehicle's operating gear into first pulse width modulation duty cycle information. The electronic shift unit parses the first pulse width modulation duty cycle information to obtain the vehicle's operating gear. By using the level signals corresponding to two wire harnesses to form a combined level value, and then determining the level control signal, the problem of wasted pin resources caused by three wire harnesses occupying three pins of the electronic shift unit is solved. Furthermore, by establishing the correspondence between the first pulse width modulation duty cycle and the vehicle's operating gear, the vehicle control unit can transmit the actual vehicle operating gear to the electronic shift unit. This solves the problem of poor anti-interference capability and instability of electrical signals when transmitting the electrical signals corresponding to the actual vehicle operating gear, which is caused by the complexity of the communication logic and physical structure of CAN network communication and the need for corresponding functional programming and network management development based on the vehicle communication architecture.

[0068] Furthermore, the electronic shift unit can also send shift fault information of the electronic shift unit to the vehicle control unit through the pulse width modulation duty cycle signal, and then the vehicle control unit sends the shift fault information to the vehicle display unit to realize feedback of the shift fault information of the electronic shift unit to the user. Figure 3 This is a schematic diagram illustrating the specific steps for transmitting and displaying shift fault information of the electronic shift unit according to an embodiment of this application, as shown below. Figure 3 As shown, the specific steps for transmitting and displaying shift fault information from the electronic shift unit include:

[0069] Step S106: The shift fault information of the electronic shift unit is converted into the second pulse width modulation duty cycle information through the electronic shift unit.

[0070] For example, by defining the correspondence between pulse width modulation duty cycle and shift fault information, the shift fault information of the electronic shift unit can be converted into second pulse width modulation duty cycle information by the electronic shift unit. More specifically, the shift fault information includes at least first fault information and second fault information; converting the shift fault information of the electronic shift unit into second pulse width modulation duty cycle information by the electronic shift unit includes: obtaining first fault duty cycle information by the electronic shift unit based on the first fault information; or, obtaining second fault duty cycle information by the electronic shift unit based on the second fault information; and obtaining second pulse width modulation duty cycle information based on the first fault duty cycle information or the second fault duty cycle information.

[0071] In one possible implementation, Table 3 illustrates the correspondence between the second pulse width modulation duty cycle and the state information of the electronic shift unit. As shown in Table 3, the state information of the electronic shift unit includes: photoelectric switch failure, Hall sensor failure, gear synchronization failure, low power supply voltage to the electronic shift unit, high power supply voltage to the electronic shift unit, and normal / dormant state of the electronic shift unit. Reserved positions are used to establish a new correspondence between the second pulse width modulation duty cycle and the state information of the electronic shift unit. The shifting fault information of the electronic shift unit includes: photoelectric... The faults include switch malfunction, Hall sensor malfunction, gear synchronization failure, low supply voltage to the electronic shift unit, and high supply voltage to the electronic shift unit. Based on the correspondence between the second pulse width modulation duty cycle and shift fault information, if the electronic shift unit detects a high supply voltage from the vehicle's infotainment system to the electronic shift unit, then the second pulse width modulation duty cycle is obtained from the electronic shift unit if it is between 40% ≤ Y < 50%, thus obtaining the second pulse width modulation duty cycle information. Here, Y is the specific value of the pulse width modulation duty cycle generated by the electronic shift unit based on the shift fault information.

[0072] Table 3

[0073] Second pulse width modulation duty cycle Status information of electronic shift unit 0≤Y<10％ Photoelectric switch malfunction 10％≤Y<20％ Hall sensor failure 20％≤Y<30％ Gear synchronization failure 30％≤Y<40％ Low power supply voltage to the electronic shift unit 40％≤Y<50％ High power supply voltage to the electronic shift unit 50％≤Y<60％ Electronic shift unit status: normal / dormant 60％≤Y<100％ Reserved space

[0074] In step S107, the second pulse width modulation duty cycle information is analyzed by the vehicle control unit to obtain the shift fault type of the electronic shift unit and display it.

[0075] For example, based on the correspondence between the second pulse width modulation duty cycle and the status information of the electronic shift unit shown in Table 3, the status information of the electronic shift unit can be determined by parsing the second pulse width modulation duty cycle information by the vehicle control unit. In other words, it can be determined whether the electronic shift unit is faulty. If the electronic shift unit is faulty, the shifting fault type of the electronic shift unit can be determined and displayed. More specifically, for example, based on the numerical range of the second pulse width modulation duty cycle determined by the electronic shift unit, the second pulse width modulation duty cycle information is determined. Then, the vehicle control unit parses the second pulse width modulation duty cycle information. That is, based on the correspondence between the second pulse width modulation duty cycle and the state information of the electronic shift unit shown in Table 3, the vehicle control unit determines the state of the electronic shift unit according to the numerical range of the second pulse width modulation duty cycle. That is, if the electronic shift unit has a fault, the shifting fault type of the electronic shift unit can be determined. For example, based on the second pulse width modulation duty cycle being between 40% ≤ Y < 50%, the fault of the electronic shift unit is "high power supply voltage of the vehicle equipment to the electronic shift unit". Then, the vehicle display unit corresponding to the vehicle control unit displays the specific fault information, that is, displays "high power supply voltage of the vehicle equipment to the electronic shift unit".

[0076] In this embodiment, by establishing the correspondence between the second pulse width modulation duty cycle and the state information of the electronic shift unit, the correspondence between the shift fault information of the electronic shift unit and the second pulse width modulation duty cycle is determined. Then, the electronic shift unit converts the shift fault information into second pulse width modulation duty cycle information, so as to display the specific fault information of the electronic shift unit on the vehicle display unit corresponding to the vehicle control unit. This solves the problem of poor anti-interference capability and instability of electrical signals when transmitting the electrical signals corresponding to shift fault information, which is caused by the complexity of the communication logic and physical structure of CAN network communication and the need for corresponding functional programming and network management development according to the vehicle communication architecture.

[0077] Figure 4 A flowchart of an electronic shift control method provided in another embodiment of this application is shown below. Figure 4 As shown, the electronic shift control method provided in this embodiment is... Figure 2 Based on the electronic shift control method provided in the illustrated embodiment, the electronic shift control method provided in this embodiment includes the following steps:

[0078] Step S201: In response to the first user's gear shifting operation, a level control signal is generated through the electronic gear shifting unit. The level control signal includes a first level value and a second level value. The combined level value formed by the first level value and the second level value is used to characterize the target electronic gear corresponding to the first user's gear shifting operation.

[0079] Step S202: Obtain the level control signal through the vehicle control unit, and obtain the user-requested gear information according to the preset level encoding table. The level encoding table is used to characterize the mapping relationship between the combined level value and the electronic gear. The user-requested gear information is used to drive the vehicle control unit to electronically switch the vehicle motor.

[0080] Step S203: The vehicle control unit determines the vehicle's operating gear based on the gear information requested by the user and the first motor's operating information. The first motor's operating information represents the operating status of the vehicle motor after the vehicle control unit responds to the gear information requested by the user.

[0081] Step S204: The vehicle operating gear is converted into the first pulse width modulation duty cycle information through the vehicle control unit.

[0082] Step S205: The vehicle's operating gear is obtained by analyzing the first pulse width modulation duty cycle information through the electronic shift unit.

[0083] In step S206, in response to the second user's gear shifting operation, a forced control signal is generated through the electronic gear shifting unit. The second user's gear shifting operation is a gear shifting operation in which the user actively changes the vehicle's gear position solely through the electronic gear shifting unit during vehicle use.

[0084] For example, during vehicle use, the conventional gear shifting operation involves pressing the brake pedal while simultaneously pressing the corresponding gear position on the electronic shift unit. In unconventional situations, the user can actively change the vehicle's gear simply by pressing the corresponding gear position on the electronic shift unit. Furthermore, to prevent accidental gear changes due to user error, a threshold number of times the corresponding gear position on the electronic shift unit can be set to determine a second user gear shifting operation. Specifically, if the number of times the user presses the corresponding gear position on the electronic shift unit exceeds the preset threshold within a preset time, a second user gear shifting operation is determined. In response to this second user gear shifting operation, the electronic shift unit, using the correspondence between the target electronic gear position and the combined voltage level values ​​shown in Table 1, generates a corresponding forced control signal.

[0085] More specifically, for example, Figure 5 This is an application scenario diagram illustrating the active gear shifting of a vehicle, as provided in an embodiment of this application. Figure 5As shown, while vehicles A and B are waiting at an intersection, user_B in vehicle B notices that vehicle A in front of him is rolling backwards. At this time, within 2 seconds, user_B can obtain a second user shift operation by pressing the "reverse gear" corresponding to the "electronic shift unit" 4 times consecutively. Then, by combining the electronic shift unit with the correspondence between the target electronic gear and the combined level value shown in Table 1, the corresponding forced control signal "0,1" can be generated. The preset threshold for the number of presses is 3.

[0086] Step S207: The vehicle control unit responds to the forced control signal to obtain the forced operation gear and converts the forced operation gear into the first pulse width modulation duty cycle information.

[0087] For example, by responding to the forced control signal through the vehicle control unit and parsing the forced control signal based on the correspondence between the target electronic gear and the combined level value shown in Table 1, the gear information corresponding to the second user's gear shifting operation can be obtained. Then, based on the gear information corresponding to the second user's gear shifting operation, the vehicle control unit is driven to electronically switch the vehicle motor's gear, thus obtaining the forced operating gear. The forced operating gear is then converted into first pulse width modulation duty cycle information, and the process returns to step S205 to determine the vehicle operating gear corresponding to the forced operating gear. In one possible implementation, the forced control signal is "0,1". The vehicle control unit parses the forced control signal "0,1" based on the correspondence shown in Table 1 to obtain the "reverse gear" corresponding to the second user's gear shifting operation. This then drives the vehicle control unit to electronically switch the vehicle motor's gear, thus obtaining the forced operating gear. The forced operating gear is then converted into first pulse width modulation duty cycle information, and the process returns to step S205 to determine the vehicle operating gear "reverse gear" corresponding to the forced operating gear.

[0088] In another possible implementation Figure 6 for Figure 5 The schematic diagram of the specific implementation steps of step S207 in the illustrated embodiment is as follows: Figure 6 As shown, the user request for gear information includes a forced request for gear information. The forced request for gear information indicates the vehicle's gear type after the user actively changes the vehicle's gear solely through the electronic shift unit during vehicle use. The specific implementation steps of step S207 include:

[0089] Step S2071: The vehicle control unit responds to the forced control signal to obtain the user request duration. The user request duration is the cumulative generation duration corresponding to the forced control signal generated by the electronic shift unit when the user actively changes the vehicle's gear position only through the electronic shift unit within a preset time.

[0090] For example, within a preset time period, the electronic shift unit records the time the user actively changes the vehicle's gear solely through the electronic shift unit, thus obtaining the cumulative generation duration corresponding to the forced control signal generated by the electronic shift unit. In other words, the user's request duration is obtained simultaneously with the vehicle control unit responding to the forced control signal. More specifically, for instance, if user_B presses the "reverse" button on the electronic shift unit four times consecutively within 2 seconds, the electronic shift unit generates the corresponding forced control signal "0,1," and obtains a corresponding user request duration of 1.2 seconds, where the preset threshold for the number of presses is 3.

[0091] Step S2072: The vehicle control unit determines the forced request gear information based on the user request duration, the preset request duration, and the level encoding table.

[0092] For example, to prevent users from accidentally changing the vehicle's gear position, a threshold number of times the "electronic shift unit" is pressed is set to determine the second user's gear shifting operation. Further verification of the second user's gear shifting operation is performed using a preset request duration. That is, if the user's request duration is greater than or equal to the preset request duration, it proves that the user has performed a continuous second user gear shifting operation to change the vehicle's current state. Therefore, by combining this with the level encoding table, the forced gear request information can be determined. If the user's request duration is less than the preset request duration, the user may have made a mistake. More specifically, for example, if user_B presses the "reverse" gear corresponding to the "electronic shift unit" four times consecutively, the electronic shift unit generates the corresponding forced control signal "0,1," and the corresponding user request duration is 1.2 seconds. If the preset request duration is 1 second, then based on the fact that the user's request duration of 1.2 seconds is greater than the preset request duration of 1 second, it is determined that the user's operation to actively change the vehicle's gear is not a mistake. Therefore, by combining this with the level encoding table, the forced gear request information can be determined.

[0093] Step S2073: The vehicle control unit obtains the forced operation gear based on the forced request gear information and the second motor operation information. The second motor operation information represents the operating state of the vehicle motor after the vehicle control unit responds to the forced request gear information.

[0094] For example, the second motor operation information represents the operating state of the vehicle motor after the vehicle control unit responds to the forced gear request information. Specifically, the vehicle control unit is driven to electronically switch the vehicle motor's gear according to the forced gear request information, thereby obtaining the vehicle motor's operating state through the vehicle control unit, i.e., obtaining the second motor operation information. Furthermore, by parsing the second motor operation information, the forced operating gear can be obtained by the vehicle control unit. More specifically, as... Figure 5In the scenario shown, the vehicle's current operating gear is "neutral". Based on the forced control signal "0,1", the forced gear request information is determined to be "reverse". If the vehicle control unit drives the vehicle motor's electronic gear to switch to "reverse" based on "reverse", the vehicle motor's operating state will be "reverse", thus obtaining the second motor's operating information. Then, the vehicle control unit analyzes the second motor's operating information corresponding to the "reverse" state to determine that the forced operating gear is "reverse".

[0095] In this embodiment, by generating a forced control signal corresponding to the second user's gear shifting operation, a quick gear shifting method is provided to the user in an emergency. Furthermore, to ensure the reliability of the quick gear shifting method, an operation count threshold and a preset request duration are introduced to verify the second user's gear shifting operation, thereby ensuring user safety.

[0096] In this embodiment, the implementation of steps S201-S205 is the same as that in this application. Figure 2 The implementation methods of steps S101-S105 in the illustrated embodiment are the same, and will not be described in detail here.

[0109] In one possible implementation, the user-requested gear information includes forced gear information, which represents the vehicle gear type after the user actively changes the vehicle gear solely through the electronic gear shift unit during vehicle operation.
