[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 31, 2024, with application number 2024101398486 and application name “Electronic shift control method, device, electronic device and storage medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] With the advancement of electrification, more and more mechanical structures in vehicles are being replaced by electronic ones, and the electronic shift unit (ESU) is one of them. The ESU's function is to transmit user-controlled shifting operations (forward, reverse, and parking) to the vehicle control unit (VCU). The VCU then performs logical analysis and controls the motor to execute the corresponding operation. Simultaneously, the VCU transmits the motor's operating status to the ESU, which requires communication between the ESU and the VCU.

[0004] Currently, the pins of the electronic shift unit and the pins of the vehicle control unit are often connected through three wiring 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 that the gear is valid, and when it is set to a low level, it means that the gear is invalid; and the actual vehicle operating gear is transmitted from the vehicle control unit to the electronic shift unit through the controller area network CAN network.

[0005] However, when changing the vehicle's operating gear through 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 operating gear to the electronic shift unit, due to the complex communication logic and physical structure of the CAN network communication, and the need for corresponding functional programming and network management development based on the vehicle communication architecture, the electrical signal has poor anti-interference ability and instability when transmitting the electrical signal corresponding to the actual vehicle operating gear.

[0037] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0038] In the technical solution of this application, the user personal information involved and the collection, storage, use, processing, transmission, provision and disclosure of data are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0039] 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, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0040] FIG1 is a diagram of an application scenario of the electronic shift control method provided in an embodiment of the present application. The electronic shift control method provided in an embodiment of the present application can be applied to a scenario in which a user shifts gears of a vehicle. For example, as shown in FIG1 , the execution subject of the method provided in an embodiment of the present application 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 generates a corresponding vehicle shift instruction in response to the user's shift operation. Then, according to the corresponding vehicle shift instruction, the vehicle control unit changes the operating state of the vehicle motor to achieve the vehicle gear switching. After the vehicle completes the gear switching, 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.

[0041] Currently, three wires are typically used to connect the pins of the electronic shift unit (ESU) to the pins of the vehicle control unit (VCU) to transmit information about reverse, neutral, and forward gears. When the ESU sets the reverse, neutral, or forward gear pins to a high level, the gear is active; when they are set to a low level, the gear is inactive. The actual vehicle gear position is then transmitted from the VCU to the ESU via the CAN network.

[0042] However, when changing the vehicle's operating gear through 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 operating gear to the electronic shift unit, due to the complex communication logic and physical structure of the CAN network communication, and the need for corresponding functional programming and network management development based on the vehicle communication architecture, the electrical signal has poor anti-interference ability and instability when transmitting the electrical signal corresponding to the actual vehicle operating gear.

[0043] The technical solution of the present application is described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0044] FIG2 is a flow chart of an electronic shift control method provided by an embodiment of the present application. As shown in FIG2 , the electronic shift control method provided by this embodiment may be executed by a vehicle-mounted device or an electronic control unit. By way of example, this embodiment is described using a vehicle-mounted device as the execution subject of the method of this embodiment. The method provided by this embodiment of the present application is applied to an electronic shift system, which includes an electronic shift unit and a vehicle control unit. The electronic shift control method provided by this embodiment includes the following steps:

[0045] In step S101, in response to a first user shifting operation, a level control signal is generated by an electronic shifting unit. The level control signal includes a first level value and a second level value. The combined level value of the first level value and the second level value is used to represent the target electronic gear position corresponding to the first user shifting operation.

[0046] For example, in communication coding, the definition of the target electronic gear position of the vehicle is realized by coordinating the high and low levels corresponding to the two wiring harnesses, that is, a combined level value is formed by the first level value corresponding to the first wiring harness and the second level value corresponding to the second wiring harness, and then four level value combinations are obtained. These four level value combinations can correspond to the four electronic gear positions of the vehicle, and then in response to the first user's gear shifting operation, the electronic gear shifting unit generates a corresponding level control signal, that is, the target electronic gear position corresponding to the first user's gear shifting operation is obtained. More specifically, for example, Table 1 is a schematic table of the correspondence between target electronic gear positions and combined level values. As shown in Table 1, "0" represents a low level of the wiring harness, and "1" represents a high level of the wiring harness. The physical forms corresponding to the vehicle's electronic gear shift unit include button-type, knob-type, hand-shift-type, and handle-type. This embodiment takes a button-type electronic gear shift unit as an example. The first user gear shift operation is that the user depresses the "brake pedal" and presses the gear position corresponding to the "electronic gear shift unit" at the same time. Then, in response to the first user gear shift operation, the electronic gear shift unit generates a combined level value, that is, generates a corresponding level control signal. For example, when the user depresses the "brake pedal" and presses the "reverse gear" corresponding to the "electronic gear shift unit" at the same time, the electronic gear 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". Then, the level control signal generated by the electronic gear shift unit is "0, 1".

[0047] Table 1

[0048] In step S102, the vehicle control unit obtains a level control signal and obtains user-requested gear information according to a preset level coding table. The level coding 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 perform electronic gear switching on the vehicle motor.

[0049] For example, the level coding table is used to characterize the mapping relationship between the combined level value and the electronic gear position, and the user-requested gear position information is used to drive the vehicle control unit to perform electronic gear switching on the vehicle motor. That is, the vehicle control unit parses and processes the acquired level control signal according to the level coding table to obtain the target electronic gear position corresponding to the first user shift operation, that is, the user-requested gear position information is obtained, and then the vehicle control unit can be driven to perform electronic gear switching on the vehicle motor according to the user-requested gear position information. More specifically, for example, Table 1 is a level coding 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. The vehicle control unit parses and processes the acquired level control signal according to the level coding table to obtain the user-requested electronic gear position, that is, the user-requested gear position information.

[0050] In one possible implementation, the electronic shift unit and the vehicle control unit are connected through two wiring harnesses (a first wiring harness and a second wiring harness) to realize the transmission of the level control signal. For example, in response to the first user shifting operation, the level control signal "0, 1" is generated by the electronic shift unit; 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, 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"; then the level control signal "0, 1" is obtained through the vehicle control unit, and then according to the level coding table, the electronic gear requested by the user is obtained as "reverse gear", that is, the gear information requested by the user is obtained.

[0051] In step S103, the vehicle control unit determines the vehicle operating gear according to the user requested gear information and the first motor operating information. The first motor operating information represents the operating state of the vehicle motor after the vehicle control unit responds to the user requested gear information.

[0052] Exemplarily, the first motor operation information represents the operating status 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 switch the electronic gear of the vehicle motor according to the user's request for gear information, and then the operating status of the vehicle motor is obtained through the vehicle control unit, that is, the first motor operation information is obtained; then, the vehicle operating gear can be determined by parsing the first motor operation information through the vehicle control unit. In one possible implementation, if the current operating gear of the vehicle is "forward gear", the user requested gear information is determined to be "reverse gear" according to the level control signal "0,1". If the vehicle control unit is driven according to the "reverse gear" to switch the electronic gear of the vehicle motor to "reverse gear", and the operating state of the vehicle motor is "reverse", the first motor operating information info_1 is obtained, and the first motor operating information info_1 corresponding to the "reverse" state is parsed by the vehicle control unit to determine that the vehicle operating gear is "reverse gear"; if the vehicle control unit is driven according to the "reverse gear" and the electronic gear of the vehicle motor is not switched to "reverse gear", and the operating state of the vehicle motor is still "forward", the first motor operating information info_2 is obtained, and the first motor operating information info_2 corresponding to the "forward" state is parsed by the vehicle control unit to determine that the vehicle operating gear is still "forward gear".

[0053] Step S104: converting the vehicle operating gear into first pulse width modulation duty cycle information through the vehicle control unit.

[0054] Exemplarily, PWM duty cycle information is used to indicate the state of a level signal, where the state of the level signal 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 a 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 a complete data cycle. By defining a correspondence between the PWM duty cycle and the vehicle's operating gear, the vehicle's operating gear can be converted into the first PWM duty cycle information by the vehicle control unit based on a predefined correspondence between the first PWM duty cycle and the vehicle's operating gear. More specifically, the vehicle operating gear includes at least a first operating gear and a second operating gear; the vehicle operating gear is converted into a first pulse width modulation duty cycle information through the vehicle control unit, including: obtaining the first gear duty cycle information according to the first operating gear through the vehicle control unit; or, obtaining the second gear duty cycle information according to the second operating gear through the vehicle control unit; obtaining the first pulse width modulation duty cycle information according to the first gear duty cycle information or the second gear duty cycle information.

[0055] In one possible implementation, Table 2 is a schematic table of the correspondence between the first pulse width modulation duty cycle and the vehicle operating gear. As shown in Table 2, the vehicle operating gear includes no request, reverse gear, neutral gear, forward gear and low speed 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 between 10%≤X<30%, that is, the first pulse width modulation duty cycle information is obtained, wherein X is the specific value of the first pulse width modulation duty cycle generated by the vehicle control unit according to the vehicle operating gear.

[0056] Table 2

[0057] Step S105 , analyzing the first pulse width modulation duty cycle information through the electronic shift unit to obtain the vehicle operating gear.

[0058] For example, based on the correspondence between the first pulse width modulation duty cycle and the vehicle operating gear shown in Table 2, the electronic shift unit analyzes the first pulse width modulation duty cycle information to determine the vehicle operating gear. More specifically, for example, based on the numerical range of the first pulse width modulation duty cycle determined by the vehicle control unit, the first pulse width modulation duty cycle information is determined, and then the electronic shift unit analyzes the first pulse width modulation duty cycle information. That is, based on the correspondence between the first pulse width modulation duty cycle and the vehicle operating gear shown in Table 2, the electronic shift unit determines the vehicle operating gear based on the numerical range of the first pulse width modulation duty cycle. For example, based on the first pulse width modulation duty cycle being between 10% ≤ X < 30%, the vehicle operating gear is determined to be "reverse gear."

[0059] Optionally, if the user presses the "forward gear" corresponding to the "electronic shift unit" while the user steps on the "brake pedal", the electronic shift unit transmits the corresponding level control signal "1,1" to the vehicle control unit, and the vehicle control unit electronically switches the vehicle motor according to the user-requested gear information determined based on the level control signal "1,1"; then, the actual operating state of the vehicle motor is obtained through the vehicle control unit, that is, the numerical range of the first pulse width modulation duty cycle determined by the vehicle control unit is 10%≤X<30%, then the vehicle operating gear is obtained as "reverse gear", and the vehicle operates according to the actual vehicle operating gear "reverse gear".

[0060] In this embodiment, an 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 shift operation, the electronic shift unit generates a level control signal, the level control signal including a first level value and a second level value. The combined level value of the first level value and the second level value is used to represent a target electronic gear position corresponding to the first user shift operation. The vehicle control unit obtains the level control signal and obtains user-requested gear position information according to a preset level coding table. The level coding table is used to represent a mapping relationship between the combined level value and the electronic gear position. The user-requested gear position information is used to drive the vehicle control unit to electronically switch the gear position of the vehicle motor. The vehicle control unit determines the vehicle operating gear position based on the user-requested gear position information and first motor operating information, the first motor operating information representing the operating state of the vehicle motor after the vehicle control unit responds to the user-requested gear position information. The vehicle control unit converts the vehicle operating gear position 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 position. By using the level signals corresponding to the two wiring harnesses to form a combined level value and then determining the level control signal, the problem of pin resource waste caused by three wiring harnesses occupying three pins of the electronic shift unit is solved. At the same time, by establishing a corresponding relationship between the first pulse width modulation duty cycle and the vehicle operating gear, the vehicle control unit can transmit the actual vehicle operating gear to the electronic shift unit, which solves the problem of poor anti-interference ability and instability of the electrical signal when transmitting the electrical signal corresponding to the actual vehicle operating gear due to the complex communication logic and physical structure of the CAN network communication and the need for corresponding functional programming and network management development according to the vehicle communication architecture.

[0061] Optionally, the electronic shift unit can also transmit the shift fault information of the electronic shift unit to the vehicle control unit via a pulse width modulation duty cycle signal, and then transmit the shift fault information to the vehicle display unit via the vehicle control unit, so as to provide feedback of the shift fault information of the electronic shift unit to the user. FIG3 is a schematic diagram of the specific steps of transmitting and displaying the shift fault information of the electronic shift unit according to an embodiment of the present application. As shown in FIG3, the specific steps of transmitting and displaying the shift fault information of the electronic shift unit include:

[0062] Step S106 : converting the shift fault information of the electronic shift unit into second pulse width modulation duty cycle information through the electronic shift unit.

[0063] For example, by defining a correspondence between a pulse width modulation duty cycle and shift fault information, the electronic shift unit can convert the shift fault information of the electronic shift unit into second pulse width modulation duty cycle information. 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 based on the first fault information by the electronic shift unit; or obtaining second fault duty cycle information based on the second fault information by the electronic shift unit; and obtaining second pulse width modulation duty cycle information based on the first fault duty cycle information or the second fault duty cycle information.

[0064] In a possible implementation, Table 3 is a schematic table of the correspondence between the second pulse width modulation duty cycle and the status information of the electronic shift unit. As shown in Table 3, the status 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. A reserved position is used to establish a new correspondence between the second pulse width modulation duty cycle and the status information of the electronic shift unit. Among them, the shift fault 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. 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; further, according to the correspondence between the second pulse width modulation duty cycle and the shift fault information, if the electronic shift unit detects that the power supply voltage of the vehicle equipment to the electronic shift unit is high, the second pulse width modulation duty cycle obtained by the electronic shift unit is between 40%≤Y<50%, that is, the second pulse width modulation duty cycle information is obtained, wherein Y is the specific value of the pulse width modulation duty cycle generated by the electronic shift unit according to the shift fault information.

[0065] Table 3

[0066] Step S107 : The vehicle control unit analyzes the second pulse width modulation duty cycle information to obtain the shift fault type of the electronic shift unit and displays it.

[0067] For example, according to the correspondence between the second pulse width modulation duty cycle and the status information of the electronic shift unit shown in Table 3, the vehicle control unit parses the second pulse width modulation duty cycle information to determine the status information of the electronic shift unit, and also to determine whether the electronic shift unit has a fault. If the electronic shift unit has a fault, the type of shift fault of the electronic shift unit can be determined and displayed. More specifically, for example, according to 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, and then the second pulse width modulation duty cycle information is parsed by the vehicle control unit. That is, 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 vehicle control unit determines the status of the electronic shift unit according to the numerical range of the second pulse width modulation duty cycle. That is, if there is a fault in the electronic shift unit, the shift fault type of the electronic shift unit can be determined. For example, according to the second pulse width modulation duty cycle being between 40%≤Y<50%, the fault of the electronic shift unit is obtained as "the power supply voltage of the vehicle-mounted equipment to the electronic shift unit is high", and then the vehicle display unit corresponding to the vehicle control unit displays specific fault information, that is, it displays "the power supply voltage of the vehicle-mounted equipment to the electronic shift unit is high".

[0068] In the steps of this embodiment, by establishing a corresponding relationship between the second pulse width modulation duty cycle and the status information of the electronic shift unit, the corresponding relationship between the shift fault information of the electronic shift unit and the second pulse width modulation duty cycle is determined, and then the shift fault information is converted into the second pulse width modulation duty cycle information by the electronic shift unit, so that the specific fault information of the electronic shift unit is displayed on the vehicle display unit corresponding to the vehicle control unit, which solves the problem of poor anti-interference ability and instability of the electrical signal when transmitting the electrical signal corresponding to the shift fault information due to the complex communication logic and physical structure of the CAN network communication and the need to perform corresponding functional programming and network management development according to the vehicle communication architecture.

[0069] FIG4 is a flow chart of an electronic shift control method provided in another embodiment of the present application. As shown in FIG4 , the electronic shift control method provided in this embodiment is a further refinement of the electronic shift control method provided in the embodiment shown in FIG2 . The electronic shift control method provided in this embodiment includes the following steps:

[0070] Step S201: In response to a first user shifting operation, a level control signal is generated by an electronic shifting unit. The level control signal includes a first level value and a second level value. The combined level value of the first level value and the second level value is used to represent the target electronic gear position corresponding to the first user shifting operation.

[0071] In step S202, the vehicle control unit obtains a level control signal and obtains user-requested gear information according to a preset level coding table. The level coding 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 perform electronic gear switching on the vehicle motor.

[0072] In step S203, the vehicle control unit determines the vehicle operating gear according to the user requested gear information and the first motor operating information. The first motor operating information represents the operating state of the vehicle motor after the vehicle control unit responds to the user requested gear information.

[0073] Step S204: converting the vehicle operating gear into first pulse width modulation duty cycle information through the vehicle control unit.

[0074] Step S205 , analyzing the first pulse width modulation duty cycle information through the electronic shift unit to obtain the vehicle operating gear.

[0075] Step S206 , in response to a second user shifting operation, generating a forced control signal through the electronic shifting unit, wherein the second user shifting operation is a shifting operation in which the user actively changes the vehicle gear position only through the electronic shifting unit during use of the vehicle.

[0076] For example, during a user's use of a vehicle, a conventional shift operation involves the user depressing the "brake pedal" while simultaneously pressing the corresponding gear position on the "electronic shift unit" to achieve a shift. In unconventional situations, a user can actively change the vehicle's gear position simply by pressing the corresponding gear position on the "electronic shift unit." Furthermore, to prevent active changes in the vehicle's gear position due to user error, a second user shift operation is determined by setting a threshold for the number of times the gear position corresponding to the "electronic shift unit" must be pressed. Specifically, within a preset time period, a second user shift operation is determined based on the number of times the user operates the gear position corresponding to the electronic shift unit exceeding the preset operation threshold. In response to the second user shift operation, the electronic shift unit generates a corresponding forced control signal based on the correspondence between the target electronic gear position and the combination level value shown in Table 1.

[0077] More specifically, for example, Figure 5 is an application scenario diagram of actively changing the vehicle gear provided by an embodiment of the present application. As shown in Figure 5, while vehicles A and B are waiting to travel at an intersection, user user_B in vehicle B finds that the vehicle in front of it, vehicle A, is slipping (reversing backward). At this time, within 2 seconds, user user_B only presses the "reverse gear" corresponding to the "electronic shift unit" on the electronic shift unit 4 times in succession to obtain the second user shift operation, and then the electronic shift unit is combined with the correspondence between the target electronic gear and the combination level value shown in Table 1 to generate the corresponding forced control signal "0, 1", where the preset press count threshold is 3 times.

[0078] Step S207 : The vehicle control unit responds to the forced control signal to obtain a forced operating gear, and converts the forced operating gear into first pulse width modulation duty cycle information.

[0079] For example, the vehicle control unit responds to the forced control signal and parses and processes the forced control signal based on the correspondence between the target electronic gear position and the combined level value shown in Table 1, thereby obtaining the gear position information corresponding to the second user shift operation. Based on the gear position information corresponding to the second user shift operation, the vehicle control unit is driven to electronically switch the gear position of the vehicle motor, thereby obtaining the forced operating gear position. The forced operating gear position is converted into first pulse width modulation duty cycle information, and the process then returns to step S205 to determine the vehicle operating gear position corresponding to the forced operating gear position. In one possible implementation, the forced control signal is "0, 1." The vehicle control unit parses and processes the forced control signal "0, 1" based on the correspondence shown in Table 1, thereby obtaining the "reverse gear" corresponding to the second user shift operation. The vehicle control unit is driven to electronically switch the gear position of the vehicle motor, thereby obtaining the forced operating gear position. The forced operating gear position is converted into first pulse width modulation duty cycle information, and the process then returns to step S205 to determine the vehicle operating gear position corresponding to the forced operating gear position as "reverse gear."

[0080] In another possible implementation, FIG6 is a schematic diagram of specific implementation steps of step S207 in the embodiment shown in FIG5 . As shown in FIG6 , the user-requested gear information includes forced-requested gear information. The forced-requested gear information represents the vehicle gear type after the user actively changes the vehicle gear only through the electronic shift unit during use of the vehicle. The specific implementation steps of step S207 include:

[0081] Step S2071, 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 time corresponding to the forced control signal generated by the electronic shift unit when the user actively changes the vehicle gear only through the electronic shift unit within the preset time.

[0082] For example, within a preset timeframe, the electronic shift unit records the time a user actively changes vehicle gears solely through the electronic shift unit, yielding the cumulative duration of the electronic shift unit's generation of mandatory control signals. This means that the user request duration is captured simultaneously with the vehicle control unit's response to the mandatory control signals. More specifically, for example, within two seconds, user user_B presses the "Reverse" button on the electronic shift unit four times in a row. The electronic shift unit generates the mandatory control signal "0, 1," and the corresponding user request duration is 1.2 seconds, given a preset threshold of three presses.

[0083] Step S2072: The vehicle control unit determines the mandatory requested gear information according to the user request duration, the preset request duration and the level coding table.

[0084] For example, to prevent user misoperation resulting in an active gear change, a threshold for the number of times the gear corresponding to the "electronic shift unit" is pressed is set. After determining a second user shift operation, the second user shift operation is further verified using a preset request duration. Specifically, if the user request duration is greater than or equal to the preset request duration, it indicates that the user has continuously performed the second user shift operation to change the vehicle's current state. Thus, combined with the level coding table, the mandatory requested gear information can be determined. If the user request duration is less than the preset request duration, the user may have misoperated. More specifically, for example, if user_B only presses the "Reverse" gear corresponding to the "electronic shift unit" four times in a row, the electronic shift unit generates the corresponding mandatory control signal "0, 1" and obtains a corresponding user request duration of 1.2 seconds. If the preset request duration is 1 second, then based on the user request duration of 1.2 seconds being greater than the preset request duration of 1 second, it is determined that the user's active gear change operation was not an error. Furthermore, combined with the level coding table, the mandatory requested gear information can be determined.

[0085] Step S2073, the vehicle control unit obtains the forced operating gear according to the forced request gear information and the second motor operating information, where the second motor operating information represents the operating state of the vehicle motor after the vehicle control unit responds to the forced request gear information.

[0086] Exemplarily, the second motor operating information represents the operating state of the vehicle's 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's motor gear according to the forced gear request information, and the vehicle control unit then obtains the operating state of the vehicle's motor, thereby obtaining the second motor operating information. Furthermore, the vehicle control unit analyzes the second motor operating information to obtain the forced operating gear. More specifically, in the scenario shown in FIG5 , the vehicle's current operating gear is "neutral," and the forced gear request information is determined to be "reverse" according to the forced control signal "0,1." If the vehicle control unit is driven to electronically switch the vehicle's motor gear to "reverse" according to the "reverse" state, the operating state of the vehicle's motor is "reverse," thereby obtaining the second motor operating information. The vehicle control unit then analyzes the second motor operating information corresponding to the "reverse" state to determine that the forced operating gear is "reverse."

[0087] In the steps of 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 situation to ensure the user's safety; optionally, to ensure the reliability of the quick gear shifting method, an operation number threshold and a preset request time are introduced to verify the second user's gear shifting operation to ensure the user's safety.

[0088] In this embodiment, the implementation method of steps S201 to S205 is the same as the implementation method of steps S101 to S105 in the embodiment shown in Figure 2 of this application, and will not be repeated here.
