DETAILED DESCRIPTION

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] The present application provides a new shift control scheme, which is implemented based on an electronic shifter. The electronic shifter has different shifting directions. The present application performs a shift operation based on a brake pedal state signal, a shifting direction, and the number of shifting directions. Among them, the electronic shifter includes various toggle-type electronic shifters with different shifting directions, such as a toggle electronic shifter with a three-point structure (i.e., with three shifting points), etc., having a first shifting direction and a second shifting direction opposite to the first shifting direction, such as left shifting and right shifting, or up shifting or down shifting, without specific limitation. Taking one of the electronic shifters used in the shift control method provided by the present application as an example, first introduce one of the electronic shifters involved in the present application.

[0069] Please also read Figure 1-Figure 9 The present embodiment provides an electronic shifter, which includes a housing 1, an operating lever 2 and a sliding rod 3. The two sides of the middle of the operating lever 2 also extend along a first rotating end 202 and a second rotating end 203 respectively. The operating lever 2 is rotatably arranged in the housing 1 through the first rotating end 201 and the second rotating end 202. The end of the operating lever 2 located above the middle portion forms an upper rod portion 203 and extends from the housing 1 to form an operating end. The end of the operating lever 2 located below the middle portion forms a lower rod portion 204. One end of the sliding rod 3 extends into the lower rod portion 204 and can move in coordination with the lower rod portion 204. The other end of the sliding rod 3 can swing and rotate in a sliding groove 103 formed in the housing 1 as the operating lever 2 deflects.

[0070] It should be noted that the electronic shifter also includes a circuit board 9 and a magnetic part 10 required for operation. The magnetic part 10 is used to generate a magnetic field. For example, the magnetic part 10 can be a magnet and be cylindrical, which is not specifically limited. The magnetic part 10 is arranged on the joystick 2. When the sliding rod 3 is in operation, the relative position of the magnetic part 10 and the circuit board 9 will change, so that the circuit board 9 senses the change in magnetic flux Φ caused by this position change through a sensing sensor such as a Hall sensor, and generates an electronic shift signal corresponding to the change. It is also worth noting that the circuit board 9 includes the basic circuit module of the required electronic shifter, and the functions that can be realized can be very complete, including or even exceeding the functions used by the current shifter, for example, it can include a wear alarm function for the shrapnel, which is not specifically limited. The main function of the circuit board 9 is to respond to the position change of the magnetic part 10 to generate an external electrical signal, and the circuit board 9 is not specifically described in detail.

[0071] It can be seen that in this embodiment, a new electronic shifter is provided, which utilizes the shaft rotation to swing left and right to generate a shift signal. Compared with the traditional electronic shifter, the electronic shifter only forms a yaw rotation by rotating the two rotating ends around the shaft. The structure is simple, which is conducive to reducing the volume of the electronic shifter, thereby making the shifter miniaturized and universal, and thus suitable for various requirements of more vehicle layout and styling.

[0072] In one embodiment, the shell 1 includes an upper shell 101 and a lower shell 102. The upper shell 101 and the lower shell 102 can be detachably assembled and installed. The upper shell 101 and the lower shell 102 are installed to form the shell 1. Other components such as the circuit board 9 are installed in the accommodating space inside the shell 1. As an example, the shell 1 as a whole can be a rectangular parallelepiped. The rectangular parallelepiped shape can be made into a rectangular or partially avoided structure without affecting the internal parts. The specific structural shape is not limited.

[0073] In one embodiment, the electronic shifter further includes a sleeve 4 and a sleeve seat 5; the sleeve seat 5 is detachably mounted at both ends of the housing 1, and the first rotating end 201 and the second rotating end 202 are respectively sleeved with the sleeve 4 and respectively fixed to the sleeve seats 5 at both ends of the housing 1.

[0074] In this embodiment, a structure for fixing two sleeve seats 5 is provided in the accommodation space formed by the housing 1, and the two sleeve seats 5 are fixedly installed on the structure, and sleeves 4 are respectively provided on both sides of the middle of the joystick 2 along the first rotating end 201 and the second rotating end 202, so that the rotating end with the sleeve 4 can be installed in the sleeve seat 5 to form a deflectable rotating structure. For example, the sleeve 4 can be cylindrical, and the sleeve seat 5 can be cylindrical with a hanging ear, which is not specifically limited.

[0075] It should be noted that, in a specific implementation, the sleeve seat 5 , the upper shell 101 and the lower shell 102 can be fixed by self-tapping screws 14 , and the specific details are not limited thereto. The sleeve seat 5 not only serves as the installation position of the sleeve 4 , but also provides a fixing point for the joystick 2 .

[0076] In this embodiment, the structure of the shaft sleeve 4 and the shaft sleeve seat 5 can reduce the friction coefficient when the joystick 2 rotates at the two rotating ends, thereby improving the stability and durability of the rotating structure.

[0077] In one embodiment, if Figure 3 As shown, the shaft sleeve 4 is provided with an opening 41 on its peripheral wall.

[0078] In this embodiment, the shaft sleeve 4 for rotating the joystick 2 is designed to be open, which can absorb the impact of poor mold precision to the greatest extent, thereby avoiding rotation problems such as inability to return to the original position and large resistance caused by the joystick 2 being locked when the electronic shifter is working, thereby improving the practicality of the electronic shifter.

[0079] In one embodiment, if Figure 2 As shown, a reset member 11 is provided between the lower portion 204 of the joystick 2 and the sliding rod 3. One end of the reset member 11 acts on the sliding rod 3, and the other end acts on the lower portion 204 of the joystick 2. Under the action of the reset member 11, when the other end of the sliding rod 3 deflects to any angle along the sliding groove 103, it returns to the initial state of the sliding rod 3.

[0080] Exemplarily, the reset member 11 can be implemented by a spring or other reset structure, and the specifics are not limited. Taking the spring as an example, the middle part of the joystick 2 is in the form of a rectangular parallelepiped as a whole, and along the length direction, the two ends extend a first rotating end 201 and a second rotating end 202 respectively, and the end of the joystick 2 located above the middle part forms an upper rod 203 and extends from the shell 1 to form a joystick end, and the end of the joystick 2 located below the middle part forms a lower rod 204, wherein the lower rod 204 of the joystick 2 is provided with a through hole, one end of the sliding rod 3 is placed in the through hole opened in the lower rod 204, and the other end of the sliding rod 3 is located in the sliding groove 103 in the shell 1, and the sliding rod 3 is sleeved with a spring 11, one end of the spring 11 abuts against the lower wall of the lower rod 204 of the joystick 2, and the other end of the spring 11 abuts against the step opened at the other end of the sliding rod 3, and the deformation of the spring is used to generate the sliding recovery ability of the sliding rod 3.

[0081] In one embodiment, the end of the lower rod portion 204 of the joystick 2 is sleeved with a buffer ring 6. Specifically, illustratively, the end of the lower rod portion 204 of the joystick 2 is provided with a groove edge 2041, and the buffer ring 6 is embedded in the groove edge 2041. Exemplarily, the cross-section of the end of the lower rod portion 204 of the joystick 2 can be circular, and the corresponding buffer ring 6 can be circular, which is not specifically limited. In this embodiment, by providing the buffer ring 6 at the end of the lower rod portion 204 of the joystick 2, due to the effect of the buffer ring 6, the polarization process of the joystick 2 can be damped and noise can be reduced, thereby reducing the noise of the electronic shifter.

[0082] In one embodiment, if Figure 4 As shown, the electronic shifter also includes a dial button 7, and the upper rod portion 203 of the joystick 2 is placed in the accommodating space of the dial button 7, and the dial button 7 and the upper rod portion 203 are fixed by an open lock pin 8. Exemplarily, one end 71 of the dial button 7 is in the shape of a fish fin 71, and the other end extends out of the surrounding wall 72. The surrounding wall 72 forms an accommodating space for the dial button 7. A through hole is provided on the surrounding wall 72, and a corresponding mounting hole is also provided on the upper rod portion 203. After the upper rod portion 203 is installed in the accommodating space of the dial button 7, the open lock pin 8 penetrates the through hole of the surrounding wall 72 and the mounting hole of the upper rod portion 203 to be fixed. The installation process is relatively simple. In the first step, the dial button 7 is first inserted into the upper rod portion 203 along the direction of the arrow, and in the second step, the open lock pin 8 is inserted into the dial button 7 along the direction of the arrow.

[0083] Exemplarily, the opening lock pin 8 may be cylindrical in shape, which is not particularly limited.

[0084] In this embodiment, since the open lock pin 8 is designed to be open, the maximum outer diameter of the open lock pin 8 is slightly smaller than the mounting hole on the upper rod portion 203. During the assembly of the open lock pin 8, the dial button 7 and the upper rod portion 203 of the joystick 2, the open lock pin 8 will be compressed to generate a radial elastic force, which generates a radial clamping force and an axial friction force, thereby firmly fixing the dial button 7 and the upper rod portion 203 of the joystick 2. The mounting structure is extremely simple, which is more conducive to the miniaturization of the electronic shifter.

[0085] In one embodiment, the electronic shifter also includes a bullet head 31, and the bullet head 12 is fixedly mounted on the other end of the sliding rod 3. The sliding rod 3 slides in cooperation with the sliding groove 103 through the bullet head 12. The bullet head shape can effectively reduce the friction between the sliding rod 3 and the sliding groove 103 and improve the sliding feel.

[0086] In one embodiment, a spring piece 121 is provided between the other end of the sliding rod 3 and the circumference of the connection between the bullet head 12. Exemplarily, three spring pieces 121 are provided between the other end of the sliding rod 3 and the circumference of the connection between the bullet head 12, and the spring pieces 121 are evenly distributed at 1020°. It should be noted that in addition to providing three spring pieces 121, other numbers and / or angles may be provided, such as 6 spring pieces 121, etc., which are not specifically limited.

[0087] In this embodiment, the design of the bullet head is further refined. The contact portion between the bullet head 12 and the sliding rod 3 is optimized from the previous cylindrical contact design to a spring-shaped shape. The springs are evenly distributed, which can eliminate the gap between the joystick 2 and the inner wall of the sliding groove 103 and maintain the friction at a good level.

[0088] In one embodiment, the sliding groove 103 is in the shape of a rack groove, and the depth of the middle portion of the sliding groove 103 is the largest, and the groove depth gradually decreases from the middle portion to the two ends of the sliding groove 103. In this way, the left and right swing range of the sliding rod 3 is limited by the positional relationship between the rack groove 103 and the housing 1, thereby forming the required gear position and swing range.

[0089] In one embodiment, the electronic shifter further includes a protective film 13 that matches the shape of the circuit board 9 . The protective film 13 covers the circuit board 9 and is used to cover the circuit board 9 to prevent dust and water, thereby ensuring the safety of the circuit board 9 .

[0090] For example, in actual use, the circuit board 9 can adopt a multi-layer design, such as a four-layer design, in which the four-layer board is stacked from top to bottom according to layer 1, layer 2, layer 3, and layer 4. Compared with the previous PCB, its size in the Z direction is slightly increased, but the size in the X and Y directions can be greatly reduced. Therefore, the size of the electronic shifter can be further reduced as a whole.

[0091] The above describes the structure of an electronic shifter provided in an embodiment of the present application, and the working principle and working process thereof are described below.

[0092] like Figure 6 As shown, Figure 6 The left schematic diagram in the middle shows the initial state of the electronic shifter, and the right schematic diagram shows one of the working states of the electronic shifter. When the joystick 2 rotates around the axis by a certain angle α, the sliding rod 3 will be driven to slide along the sliding groove 103. The end of the sliding rod 3 is squeezed by the sliding groove 103, and the spring 11 is deformed to generate an axial force. The force diagram at this time is as shown in FIG. Figure 7As shown, it can be seen that when the driver operates the dial button 7 to rotate a certain angle α, at this time: β is the bevel angle of the tooth shape on the sliding groove 103, N is the elastic force on the sliding rod 3, μ is the friction coefficient of the sliding groove 103 on the sliding rod 3, F is the rod force of the driver operating the joystick 2, f is the friction force on the curved surface of the sliding groove 103 on the sliding rod 3, G is the gravity of the sliding rod 3, Ft is the spring force on the sliding rod 3, k is the spring stiffness, and x is the spring compression. The following relationship exists:

[0093] Ft = kx;

[0094] N = G*cosβ+Ft*cos(β-α);

[0095] f = N * μ;

[0096] G*sinβ+Ft*sin(β-α)=f+F*cosβ

[0097] It can be seen that in static balance, the force F felt by the driver is mainly generated by Ft. When the driver lets go, F disappears, as shown in Figure 8 As shown, at this time, G*sinβ+Ft*sin(β-α)>f, and the joystick 2 will deflect to the initial position.

[0098] like Fig. 9 As shown, when the joystick 2 rotates around the axis by a certain angle α, the Hall sensor on the circuit board 9 senses the change in magnetic flux φ1<φ, and the change in magnetic flux will cause a change in the potential of the signal collection circuit inside the sensor in the circuit board 9, thereby generating an external electrical signal to form a shift request signal.

[0099] like Fig.10 As shown, illustratively, the electronic shifter in the embodiment of the present application is a three-point structure, which can be limited by the groove shape of the sliding groove 103, thereby forming a three-point sliding structure. When the joystick 2 rotates to the left around the axis by a certain angle α, it is the L1 gear, when the joystick 2 rotates to the right around the axis by a certain angle α, it is the R1 gear, and when the joystick 2 rotates around the axis, it is the 0 gear, that is, the electronic shifter is in the initial state. This is the case of left and right shifting. Of course, when the arrangement relationship of the electronic shifter changes accordingly, the above-mentioned first shifting direction and the second shifting direction can also be understood as up and down shifting, and there is no specific limitation. Here, only the left and right are used as examples for explanation.

[0100] Based on the electronic shifter provided above, such as Fig.11 As shown, an embodiment of the present application provides a shift control method, which can be applied to a vehicle controller VCU of a car, including:

[0101] S10: Detecting a brake pedal state signal and a gear position signal, wherein the gear position signal includes a gear shifting direction and a number of times the gear shifting direction is shifted;

[0102] S20: Execute a gear shifting operation according to the brake pedal state signal, the shifting direction and the number of times the shifting direction is performed.

[0103] In this embodiment, the brake pedal of the automobile is provided with a pedal sensor, and the brake pedal status signal can be collected by the pedal sensor. The brake pedal status signal indicates whether the brake pedal is pressed. The vehicle controller can detect the brake pedal status signal through the pedal sensor. In addition, the vehicle controller can also receive a gear position signal, which includes the gear shifting direction and the number of times the gear shifting direction is pressed. For example, Fig.10 Taking the shifting diagram shown as an example, the shifting directions include left and right. The vehicle controller will detect the driver's shifting direction and the corresponding number of shifting times, and then perform the gear shifting operation according to the brake pedal status signal, the shifting direction and the number of shifting directions.

[0104] It can be seen that in this embodiment, a shift control method is provided. The shift control method is based on a shift strategy with a simple toggle type electronic shifter. The shift operation can be performed according to the brake pedal state signal, the toggle direction and the number of toggle directions. The method is simple and efficient and is also applicable to Figure 1 The three-point shift structure of the electronic shifter shown.

[0105] It should be noted that if Fig.10 In the example of the present application, the electronic shifter includes two shifting directions: left shifting and right shifting. Based on this, different shifting strategies are proposed according to the actual shifting situation of the driver, which are described below.

[0106] In one embodiment, if Fig.12 As shown, in the above step S20, that is, according to the brake pedal state signal, the shifting direction and the number of times the shifting direction is performed, the shifting operation includes:

[0107] When the brake pedal is pressed and the first preset number of times is moved in the first moving direction, when the moving interval is less than the first preset time, a request to enter the N gear is executed;

[0108] When the brake pedal is pressed and the first preset number of times is moved in the first moving direction, when the moving interval is greater than or equal to the first preset time, a P gear request is executed;

[0109] When the brake pedal is pressed and the second preset number of times is moved in the first direction, the request to enter the R gear is executed.

[0110] Exemplarily, taking the three-point electronic shifter structure exemplified in the present application as an example, the first拨动 direction can be a leftward拨动, and the second拨动 direction can be a rightward拨动, which specifically depends on the structure of the拨动-type electronic shifter and is not limited herein.

[0111] Exemplarily, the first preset number of times is 2, and the second preset number of times is 1. Of course, the first preset number of times and the second preset number of times can also be other numbers of times, which are also set in advance according to needs. Similarly, the first preset duration T1 can also be pre-configured according to experience or needs, and is not specifically limited.

[0112] For simplicity of processing and to improve the shifting feeling and shifting convenience, the first preset number of times is 2, and the second preset number of times is 1. Taking this as an example, that is to say, a shifting control strategy for leftward拨动 is provided in this embodiment, namely:

[0113] When the driver presses the brake pedal and拨向左 twice, and the interval duration t between these two leftward拨 is less than T1, then a request to shift into N gear is executed;

[0114] When the driver presses the brake pedal and拨向左 twice, and the interval duration t between these two leftward拨 is greater than or equal to T1, then a request to shift out of P gear is executed;

[0115] When the driver presses the brake pedal and拨向左 once, then a request to shift into R gear is executed.

[0116] In this embodiment, a shifting control method for the leftward拨 case is provided. In combination with the拨动-type electronic shifter, by leftward拨 and the number of拨 of one / two times, it is possible to quickly switch among N gear, P gear, and R gear, which is fast, simple, and has high practicality, providing a new shifting idea for the miniaturized electronic shifter.

[0117] In one embodiment, in S20, that is, according to the brake pedal state signal, the拨动 direction, and the number of times of the拨动 direction, a shifting operation is performed, and it further includes:

[0118] When in the state of pressing the brake pedal and拨向 the second拨动 direction for the third preset number of times, when the拨动 interval duration is less than the second preset duration, then a request to shift into N gear is executed;

[0119] When in the state of pressing the brake pedal and拨向 the second拨动 direction for the third preset number of times, when the拨动 interval duration is greater than or equal to the second preset duration, then a request to shift out of P gear is executed;

[0120] When in the state of pressing the brake pedal and拨向 the second拨动 direction for the fourth preset number of times, then a request to shift into D gear is executed.

[0121] Exemplarily, taking the three-point electronic shifter exemplified in this application as an example, the first拨动 direction can be a leftward拨, and the second拨动 direction can be a rightward拨, which specifically depends on the toggle-type electronic shifter and is not limited here.

[0122] Exemplarily, the third preset number of times is 2, and the fourth preset number of times is 1. Of course, the third preset number of times and the fourth preset number of times can also be other numbers of times, which can be set in advance according to needs. Similarly, the second preset duration T2 can also be pre-configured according to experience or needs, and is not specifically limited.

[0123] It should be noted that the second preset duration T2 and the first preset duration T1 can be the same, and are not specifically limited.

[0124] For simplicity of processing, to improve the shifting feeling and shifting convenience, the third preset number of times is 2, and the fourth preset number of times is 1. Taking this as an example, that is to say, a shifting control strategy for rightward拨 is provided in this embodiment, that is:

[0125] When the driver presses the brake pedal and拨rightward twice, and the interval duration t between these two rightward拨s is < T2, then execute the N gear request;

[0126] When the driver presses the brake pedal and拨rightward twice, and the interval duration t between these two rightward拨s is ≥ T2, then execute the P gear request;

[0127] When the driver presses the brake pedal and拨rightward once, then execute the D gear request.

[0128] In this embodiment, a shifting control method for the rightward拨 case is provided. Combining with the toggle-type electronic shifter, by rightward拨 and the number of拨s of one / two times, it is possible to quickly switch between N gear, P gear, and D gear, which is fast, simple, and has high practicability, providing a new shifting idea for the miniaturized electronic shifter.

[0129] It should be noted that, exemplarily, the above R gear refers to the reverse gear, the P gear refers to the parking gear, the N gear refers to the neutral gear, and the D gear refers to the forward gear.

[0130] In addition, it should also be noted that the above-mentioned execution of the request for the corresponding gear is also to switch the current gear of the vehicle to the gear corresponding to the request. For example, executing the D gear request means switching the current gear of the vehicle to the D gear. For example, when the current is the P gear and after switching to the D gear, the operation of entering the D gear and exiting the P gear is realized.

[0131] In addition, as Fig.12 shown, when the vehicle does not trigger the P gear button, the steps of the shifting operation can be executed according to the brake pedal state signal, the拨direction, and the number of拨s of the拨direction.

[0132] In one embodiment, the method further comprises:

[0133] S30: when the P gear button is in a triggered state, determining whether a joystick of an electronic gear shifter is operated;

[0134] S40: when the joystick of the electronic shifter is not operated, determining the relationship between the driving speed and the first preset driving speed;

[0135] S50: When the vehicle speed is greater than or equal to the first preset vehicle speed, a request to enter the N gear is executed;

[0136] S60: When the vehicle speed is less than the first preset vehicle speed, a request to enter the P gear is executed.

[0137] In this embodiment, a P gear button is provided on the center console or steering wheel of the car. The P gear button can be a physical button or a virtual button, and there is no specific limitation. When the P gear button is triggered, the car generally enters the P gear state.

[0138] In this embodiment, if Fig.13 As shown, for example, after executing the N gear request, the R gear request or the R gear request, the vehicle drives according to the driver's intention. Then, when the P gear button is triggered, the driver may mistakenly trigger the electronic shifter, that is, mistakenly operate the joystick of the electronic shifter. In view of this situation, the embodiment of the present application provides a corresponding processing strategy, namely:

[0139] When the joystick of the electronic shifter is not operated, the relationship between the driving speed and the first preset driving speed will be judged. When the driving speed is greater than or equal to the first preset driving speed, the request to enter the N gear will be directly executed. When the driving speed is less than the first preset driving speed, the request to enter the P gear will be executed.

[0140] Among them, the first preset driving speed S 1 It can be obtained through calibration of the actual vehicle, and there is no specific limitation.

[0141] It should also be noted that, in one embodiment, when the vehicle speed is greater than or equal to the first preset vehicle speed, after executing the N gear request, the relationship between the vehicle speed and the first preset vehicle speed will continue to be judged. When the vehicle speed is greater than or equal to the first preset vehicle speed, the N gear request will continue to be executed. When the vehicle speed is less than the first preset vehicle speed, the P gear request will be executed.

[0142] In this embodiment, when the P gear button is in the triggered state and the electronic shifter is not accidentally touched, when the driving speed is greater than or equal to the first preset driving speed, it means that parking is not required at this time, so it is necessary to execute the N gear entry request to realize the N gear entry, so as to ensure the vehicle's driving; when the driving speed is less than the first preset driving speed, it means that the driving speed is relatively low at this time, and the probability of being in a working condition requiring parking is high, so the P gear entry request is executed, thereby realizing the P gear entry to ensure successful parking.

[0143] In one embodiment, after S30, that is, after determining whether the joystick of the electronic shifter is operated, the method further includes:

[0144] S70: when the joystick of the electronic shifter is operated, determining the relationship between the driving speed and the second preset driving speed;

[0145] S80: When the driving speed is greater than or equal to the second preset driving speed, maintaining the driver's current intended driving state;

[0146] S90: When the vehicle speed is less than the second preset vehicle speed, a request to enter the P gear is executed.

[0147] In this embodiment, when the P gear button is triggered and the electronic gear shifter is operated, the embodiment of the present application provides a corresponding processing strategy for this situation, namely:

[0148] Please continue reading Fig.13 As shown, when the P gear button is pressed and the joystick of the electronic shifter is operated, the relationship between the driving speed and the second preset driving speed will be judged. When the driving speed is greater than or equal to the first preset driving speed, the driver's current intended driving state must be maintained. When the driving speed is less than the first preset driving speed, it means that there is a current parking demand, and the request to enter the P gear will be executed.

[0149] Similarly, the second preset driving speed S 2 It can be obtained through calibration of the actual vehicle, and there is no specific limitation.

[0150] It should be noted that the first preset driving speed S 1 and the second preset driving speed S 2 The same vehicle speed may be used without any specific limitation.

[0151] In this embodiment, when the P gear button is in the triggered state and the joystick of the electronic shifter is operated, when the driving speed is greater than or equal to the second preset driving speed, it means that parking is not required at this time, and it is necessary to drive according to the driver's wishes. At this time, the driver's current intended driving state is maintained, that is, driving in response to the driver's operation, such as driving in response to the driver's acceleration, shifting and other operation intentions, to ensure the driver's normal driving needs; when the driving speed is less than the first preset driving speed, it means that the driving speed is relatively low at this time, and the probability of being in a working condition requiring parking is high. In this way, the request to enter the P gear is directly executed according to the state of the P gear button, thereby realizing entering the P gear to ensure successful parking.

[0152] In one embodiment, when the vehicle speed is greater than or equal to a second preset vehicle speed, the method further includes:

[0153] S100: The control instrument issues an alarm indication of false triggering of the electronic shifter.

[0154] In this embodiment, when the P gear button is in the triggered state and the joystick of the electronic shifter is operated, when the driving speed is greater than or equal to the second preset driving speed, it means that parking is not required at this time, and it is necessary to drive according to the driver's wishes. At this time, the driver's current intended driving state is maintained, that is, driving in response to the driver's operation, such as driving in response to the driver's acceleration, shifting and other operation intentions, to ensure the driver's normal driving needs, and the instrument can also be controlled to issue an alarm indication of the false triggering of the electronic shifter to prompt the driver.

[0155] In one embodiment, if Fig.14 As shown, before step S20, that is, before performing the gear shifting operation according to the brake pedal state signal, the toggle direction and the number of toggle directions, the method further includes:

[0156] S101: After the vehicle is powered on, triggering the execution of the vehicle gear position inspection;

[0157] S102: When the vehicle gear position inspection passes, the electronic gear shifter is controlled to perform a self-inspection;

[0158] S103: After the electronic shifter passes the self-check, the vehicle gear is switched to the P gear, and it is determined whether the P gear button is in a triggered state;

[0159] S104: when the P gear button is not in the triggered state, triggering the step of executing the gear shifting operation according to the brake pedal state signal, the toggle direction and the number of toggle directions;

[0160] S105: When the P gear button is in the triggered state, the P gear is maintained.

[0161] After the car is powered on, that is, after the on gear is turned on, the vehicle controller will trigger the execution of the car gear inspection, including checking whether the communication between the vehicle controller and the electronic shifter is normal, to determine whether the vehicle controller can receive the gear request, etc. When the car gear inspection cannot be passed, it means that the car cannot be ready (Ready), and the shift control method provided by this application is not executed at this time. When the car gear inspection is passed, the electronic shifter is controlled to perform self-inspection, and the electronic shifter self-inspection includes whether the circuit board function of the electronic shifter can be realized, etc. When the electronic shifter self-inspection cannot pass, it means that there is a problem with the electronic shifter, and the shift operation cannot be realized based on the electronic shifter. The instrument can prompt that the electronic shifter has a fault. When the electronic shifter self-inspection passes, a P gear request is executed, and then the P gear button is continuously judged whether it is in a triggered state. When it is in a triggered state, the P gear state is maintained; when it is not in a triggered state, it can trigger the step of performing the shift operation according to the brake pedal state signal, the toggle direction and the number of toggle directions.

[0162] In this embodiment, before executing the gear shift, the gear position inspection and the self-check of the electronic gear shifter are first performed to ensure the normal implementation of the subsequent gear shift control, and when an error occurs, a prompt will be given to ensure that the problem can be quickly detected and resolved.

[0163] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution.
