Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and in particular to a vehicle gear shifting control method and a vehicle gear shifting device. Background Art

[0002] When driving a vehicle, sometimes there will be some emergency situations that require the driver to react quickly and shift into reverse gear. However, in an emergency, the time left for the driver to react is usually very short, and people may be in a hurry and shift into the wrong gear when facing danger, especially in today's automatic transmission vehicles. There is no significant positional difference between the reverse gear and the forward gear. Some automatic transmission vehicles have P gear, R gear, N gear, D gear, and M gear all in a straight line. In an emergency, the driver will quickly push the gear lever, and it is very likely that due to excessive force, too fast operation speed or nervousness, it will be difficult to accurately position the gear in the R gear position in a very short time, thus losing the best opportunity to escape.

[0003] There is currently no effective solution to the above technical problems. Summary of the invention

[0016] In some of the embodiments, when the shift lever is located at the reverse gear position of the transmission mechanism and it is detected that the shift lever is subjected to a continuous thrust, the vibration intensity generated by the vibration device is increased.

[0017] In some of the embodiments, when the shift lever is located at the reverse gear position of the transmission mechanism, it is determined that the first button is released and the first electromagnetic force device stops generating magnetic force.

[0018] In some of the embodiments, when the gear lever is in the reverse gear position of the transmission mechanism, it is determined that the first button is released, and the first electromagnetic force device continues to generate magnetic force; after a first preset time period, the first electromagnetic force device stops generating magnetic force, and / or when it is detected that the first button is pressed twice in succession within a second preset time period, the first electromagnetic force device stops generating magnetic force.

[0019] In a second aspect, the present invention provides a vehicle gear shifting device, comprising:

[0026] The first electromagnetic force device is used to generate a magnetic force when the first button is pressed and the shift lever is located in the reverse gear position of the transmission mechanism;

[0027] When the gear lever is located at the reverse gear position of the speed change mechanism, the gear lever cannot move due to the attraction of the magnetic force generated by the first electromagnetic force device.

[0028] In some of the embodiments, a vibration device is further included, located on the gear lever;

[0029] The vibration device is used to generate vibration when the shift lever moves to the reverse gear position of the speed change mechanism;

When the driver quickly moves the gear lever to the reverse gear position of the transmission mechanism, the gear lever cannot be moved further under the attraction of the magnetic force generated by the first electromagnetic force device. As a result, the driver can quickly and accurately position the gear lever in the reverse gear position in an emergency, and will not be unable to accurately position the gear in the reverse gear position in a very short time due to excessive force, too fast operating speed or tension, thereby buying time for the driver and passengers to avoid danger.

[0051] See also Figure 1 , Figure 2 , Figure 1 A schematic top view of a vehicle gear shifting device provided by an embodiment of the present invention is shown in FIG. Figure 2 A partial cross-sectional schematic diagram of a reverse gear position of a vehicle gear-engaging device provided in an embodiment of the present invention when the gear lever is in the reverse gear position of the transmission mechanism. The vehicle gear-engaging device comprises a transmission mechanism 1, a gear lever 2, a first electromagnetic force device 3, a first button 4, a vibration device 5, and an electromagnetic force shielding device 6.

[0052] The gear lever 2 of the vehicle gear shifting device provided in this embodiment is provided with a first button 4;

[0053] Furthermore, the first button 4 is located at an upper position of the gear lever 2, which is a position that can be touched by the thumb when the driver holds the top of the gear lever, so that the driver can quickly press the first button 4 when holding the top of the gear lever.

[0054] The transmission mechanism 1 of the vehicle gear shifting device provided in this embodiment has a total of five gears, namely P gear, R gear (i.e., reverse gear position), N gear, D gear, and M gear; wherein a first electromagnetic force device 3 is provided at the R gear position (i.e., reverse gear position), and the first electromagnetic force device 3 is composed of two electromagnets, which are respectively located on the left and right sides of the R gear position (i.e., reverse gear position), and the two electromagnets of the first electromagnetic force device 3 have a side facing the gear lever 2 that is an arc surface. When the gear lever 2 is in the R gear position (i.e., reverse gear position), the gear lever 2 is located between the two electromagnets of the first electromagnetic force device 3. Under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., reverse gear position) and cannot be moved.

[0055] Furthermore, an electromagnetic force shielding device 6 is provided around the two electromagnets of the first electromagnetic force device 3 in the R gear position (i.e., the reverse gear position), and the electromagnetic force shielding device 6 can constrain the electromagnetic force within the R gear position (i.e., the reverse gear position), that is, Figure 3The area A filled with dotted lines as shown prevents the electromagnetic force from acting on other positions, thereby preventing the gear lever 2 from being attracted by the two electromagnets of the first electromagnetic force device 3 that have generated electromagnetic force when the gear lever 2 is in the P gear position, the N gear position, the D gear position, and the M gear position, causing the gear lever 2 to be in the R gear position (i.e., the reverse gear position), thereby improving driving safety and controllability.

[0056] In one embodiment, when the vehicle needs to be reversed in some emergency situations, when the driver presses the first button 4, the two electromagnets of the first electromagnetic force device 3 generate magnetic force. Due to the electromagnetic force shielding device 6, the two electromagnets of the first electromagnetic force device 3 will not generate attraction to the gear lever 2. When the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved. In this embodiment, before the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the two electromagnets of the first electromagnetic force device 3 generate magnetic force. When the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), it is immediately attracted by the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, effectively ensuring that the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) in a timely manner.

[0057] In another embodiment, when reversing is required in some emergency situations, when the driver presses the first button 4 and the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the two electromagnets of the first electromagnetic force device 3 generate magnetic force. Under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved. Since the two electromagnets of the electromagnetic force device 3 can generate electromagnetic force in a very short moment after being energized, the electromagnetic force is generated only when the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), which can also ensure that the gear lever 2 is stabilized in the R gear position (i.e., the reverse gear position) in a timely manner. More importantly, when the driver has no intention of shifting to the R gear (reverse gear) and the gear lever 2 is in other gears (P gear, N gear, D gear, M gear), this embodiment can prevent the driver from accidentally pressing the first button 4, which causes the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 to suck the gear lever 2 to the R gear position (i.e., the reverse gear position). In particular, in special circumstances, for example, when the two electromagnets of the first electromagnetic force device 3 in the R gear position (i.e., the reverse gear position) are not properly electromagnetically shielded or the shielding function of the electromagnetic force shielding device 6 fails, the gear lever 2 may be sucked to the R gear position (i.e., the reverse gear position) by the two electromagnets of the first electromagnetic force device 3, thereby affecting the driving safety and controllability.

[0058] Furthermore, in order to better ensure that when the driver has no intention to shift to the R gear (reverse gear) and the gear lever 2 is in other gears (P gear, N gear, D gear, M gear), the driver mistakenly presses the first button 4, causing the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 to suck the gear lever 2 to the R gear position (i.e., the reverse gear position), in another embodiment, as Figure 4 As shown, the distance L1 between the R gear position (i.e., the reverse gear position) and its adjacent gear position (e.g., the P gear and the N gear) is greater than the distance L2 between other adjacent gear positions, and the distance L1 is sufficient to ensure that the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 cannot generate sufficient attraction to the gear lever when it is in other gear positions (e.g., the P gear and the N gear). In this embodiment, the electromagnetic force shielding device 6 can also be provided at the same time, thereby playing a double insurance role.

[0059] Furthermore, the vibration device 5 is located at the top of the gear lever 2. When the driver pushes the gear lever 2 to the R gear position (i.e., the reverse gear position) after pressing the first button 4, the vibration device 5 generates vibration. Since the driver holds the top of the gear lever 2, the driver can feel the vibration at this time, thereby prompting the driver that the gear lever 2 is currently in the R gear position (i.e., the reverse gear position).

[0060] Furthermore, when the gear lever 2 is already in the R gear position (i.e., the reverse gear position), if the driver continues to push the gear lever 2, the vibration intensity generated by the vibration device 5 increases to remind the driver that the gear lever 2 is already in the R gear position (i.e., the reverse gear position) and is stabilized in the R gear position (i.e., the reverse gear position) under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 and cannot be moved, reminding the driver not to forcefully push the gear lever 2.

[0061] Furthermore, the position where the gear lever 2 cooperates with the first electromagnetic force device 3 is made of ferromagnetic material.

[0062] In another embodiment, a second electromagnetic force device (not shown in the figure) is provided at the position where the gear lever 2 cooperates with the first electromagnetic force device 3. The second electromagnetic force device can generate a magnetic force that attracts the magnetic force generated by the first electromagnetic force device 3, so as to ensure that the gear lever 2 can be stably fixed in the R gear position (i.e., the reverse gear position) and cannot be moved. The second electromagnetic force device can generate magnetic force in the following two situations: (1) when the first button 4 is pressed, the second electromagnetic force device generates magnetic force; (2) when the first button 4 is pressed and the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the second electromagnetic force device generates magnetic force.

[0063] See also Figure 5 , Figure 5 A schematic diagram of a vehicle gear shift control method provided by an embodiment of the present invention, the method is applied to Figure 1-4The specific structure of the vehicle gear-engaging device is as described above and will not be described in detail here. The method comprises the following steps:

[0064] Step 501, determine that the first button is pressed, and execute step 502;

[0065] Specifically, when the driver presses the first button 4 , the vehicle control system may detect that the first button 4 is pressed through a sensor.

[0066] In step 502 , the first electromagnetic force device generates magnetic force, and then step 503 is executed.

[0067] Specifically, the vehicle control system can detect through the sensor that the first button 4 is pressed, and then control the two electromagnets of the first electromagnetic force device 3 to generate magnetic force.

[0068] In this embodiment, the first button is pressed, which includes at least the following two situations:

[0069] (1) The first electromagnetic force device will generate magnetic force only when the first button is pressed and not released. If the first button is released, that is, the first button is reset, the first electromagnetic force device stops generating magnetic force;

[0070] (2) When the first button is pressed, the first electromagnetic force device will continue to generate magnetic force regardless of whether it is released, that is, regardless of whether the first button is reset.

[0071] Step 503: When the gear lever is located at the reverse gear position of the transmission mechanism, the gear lever cannot move due to the attraction of the magnetic force generated by the first electromagnetic force device.

[0072] Specifically, after the driver presses the first button 4, when the driver pushes the gear lever 2 to the R gear position (i.e., the reverse gear position), under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved.

[0073] By adopting the vehicle gear shifting control method provided by this embodiment, when reversing is required in some emergency situations, the driver can press the first button 4, and the first electromagnetic force device 3 generates magnetic force. When the driver quickly moves the gear lever 2 to the R gear position (i.e., the reverse gear position) of the transmission mechanism, the gear lever 2 cannot be moved further under the attraction of the magnetic force generated by the first electromagnetic force device 3, so that the driver can quickly and accurately position the gear lever 2 in the R gear position (i.e., the reverse gear position) in an emergency situation, and will not be unable to accurately position the gear position 2 in the R gear position (i.e., the reverse gear position) in a very short time due to excessive force, too fast operation speed or tension, thereby buying time for the driver and passengers to avoid danger. In addition, the vehicle gear shifting control method provided by this embodiment can generate magnetic force before the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), and when the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), it is immediately attracted by the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, effectively ensuring that the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) in a timely manner.

[0074] See also Figure 6 , Figure 6 A schematic diagram of another vehicle gear shift control method provided by an embodiment of the present invention, wherein the method is applied to Figure 1-4 The specific structure of the vehicle gear-engaging device is as described above and will not be described in detail here. The method comprises the following steps:

[0075] Step 601, determine that the first button is pressed, and execute step 602;

[0076] Specifically, when the driver presses the first button 4 , the vehicle control system may detect that the first button 4 is pressed through a sensor.

[0077] Step 602, determining that the gear lever is in the reverse gear position of the transmission mechanism, and executing step 603;

[0078] Specifically, when the driver presses the first button 4 , the vehicle control system can detect through the sensor that the shift lever 2 is pushed to the R gear position (ie, the reverse gear position).

[0079] In step 603 , the first electromagnetic force device generates magnetic force, and then step 604 is executed.

[0080] Specifically, the vehicle control system detects that the first button 4 is pressed, at which time the two electromagnets of the first electromagnetic force device 3 do not generate magnetic force. When the vehicle control system further detects that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the two electromagnets of the first electromagnetic force device 3 are controlled to generate magnetic force.

[0081] In this embodiment, the first button is pressed, which includes at least the following two situations:

[0082] (1) The first electromagnetic force device will generate magnetic force only when the first button is pressed and not released. If the first button is released, that is, the first button is reset, the first electromagnetic force device stops generating magnetic force;

[0083] (2) When the first button is pressed, the first electromagnetic force device will continue to generate magnetic force regardless of whether it is released, that is, regardless of whether the first button is reset.

[0084] Since the two electromagnets of the electromagnetic force device 3 can generate electromagnetic force in a very short moment after being energized, the electromagnetic force is generated only when the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), which can also ensure that the gear lever 2 is stabilized in the R gear position (i.e., the reverse gear position) in a timely manner. More importantly, when the driver has no intention of shifting to the R gear (reverse gear) and the gear lever 2 is in other gears (P gear, N gear, D gear, M gear), this embodiment can prevent the driver from accidentally pressing the first button 4, which causes the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 to suck the gear lever 2 to the R gear position (i.e., the reverse gear position). In particular, in special circumstances, for example, when the two electromagnets of the first electromagnetic force device 3 in the R gear position (i.e., the reverse gear position) are not properly electromagnetically shielded or the shielding function of the electromagnetic force shielding device 6 fails, the gear lever 2 may be sucked to the R gear position (i.e., the reverse gear position) by the two electromagnets of the first electromagnetic force device 3, thereby affecting the driving safety and controllability.

[0085] Step 604: When the gear lever is located at the reverse gear position of the transmission mechanism, the gear lever cannot move due to the attraction of the magnetic force generated by the first electromagnetic force device.

[0086] Specifically, after the driver presses the first button 4, when the driver pushes the gear lever 2 to the R gear position (i.e., the reverse gear position), under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved.

[0087] By adopting the vehicle gear shifting control method provided by this embodiment, when reversing is required in some emergency situations, the driver can press the first button 4, and the first electromagnetic force device 3 generates a magnetic force. When the driver quickly moves the gear lever 2 to the R gear position (i.e., the reverse gear position) of the transmission mechanism, the gear lever 2 cannot be moved further under the attraction of the magnetic force generated by the first electromagnetic force device 3, so that the driver can quickly and accurately position the gear lever 2 in the R gear position (i.e., the reverse gear position) in an emergency, and will not be unable to accurately position the gear 2 in the R gear position (i.e., the reverse gear position) in a very short time due to excessive force, too fast operating speed or tension, thereby buying time for the driver and passengers to avoid danger.

[0088] See also Figure 7 , Figure 7 A schematic diagram of another vehicle gear shift control method provided by an embodiment of the present invention, wherein the method is applied to Figure 1-4 The specific structure of the vehicle gear-engaging device is as described above and will not be described in detail here. The method comprises the following steps:

[0089] Step 701, determine that the first button is pressed, and execute step 702;

[0090] Specifically, when the driver presses the first button 4 , the vehicle control system may detect that the first button 4 is pressed through a sensor.

[0091] Step 702, determining that the gear lever is in the reverse gear position of the transmission mechanism, and executing steps 703 and 704;

[0092] Specifically, when the driver presses the first button 4 , the vehicle control system can detect through the sensor that the shift lever 2 is pushed to the R gear position (ie, the reverse gear position).

[0093] In step 703 , the first electromagnetic force device generates magnetic force, and then step 705 is executed.

[0094] Specifically, the vehicle control system detects that the first button 4 is pressed, at which time the two electromagnets of the first electromagnetic force device 3 do not generate magnetic force. When the vehicle control system further detects that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the two electromagnets of the first electromagnetic force device 3 are controlled to generate magnetic force.

[0095] In this embodiment, the first button is pressed, which includes at least the following two situations:

[0096] (1) The first electromagnetic force device will generate magnetic force only when the first button is pressed and not released. If the first button is released, that is, the first button is reset, the first electromagnetic force device stops generating magnetic force;

[0097] (2) When the first button is pressed, the first electromagnetic force device will continue to generate magnetic force regardless of whether it is released, that is, regardless of whether the first button is reset.

[0098] Since the two electromagnets of the electromagnetic force device 3 can generate electromagnetic force in a very short moment after being energized, the electromagnetic force is generated only when the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), which can also ensure that the gear lever 2 is stabilized in the R gear position (i.e., the reverse gear position) in a timely manner. More importantly, when the driver has no intention of shifting to the R gear (reverse gear) and the gear lever 2 is in other gears (P gear, N gear, D gear, M gear), this embodiment can prevent the driver from accidentally pressing the first button 4, which causes the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 to suck the gear lever 2 to the R gear position (i.e., the reverse gear position). In particular, in special circumstances, for example, when the two electromagnets of the first electromagnetic force device 3 in the R gear position (i.e., the reverse gear position) are not properly electromagnetically shielded or the shielding function of the electromagnetic force shielding device 6 fails, the gear lever 2 may be sucked to the R gear position (i.e., the reverse gear position) by the two electromagnets of the first electromagnetic force device 3, thereby affecting the driving safety and controllability.

[0099] Step 705: When the gear lever is located at the reverse gear position of the transmission mechanism, the gear lever cannot move due to the attraction of the magnetic force generated by the first electromagnetic force device.

[0100] Specifically, after the driver presses the first button 4, when the driver pushes the gear lever 2 to the R gear position (i.e., the reverse gear position), under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved.

[0101] In step 704 , the vibration device generates vibration, and then step 706 is executed.

[0102] Specifically, the vehicle control system can detect through the sensor that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), and at this time the vehicle control system controls the vibration device 5 to generate vibration. Since the driver holds the top of the gear lever 2, the driver can feel the vibration at this time, thereby prompting the driver that the gear lever 2 is currently in the R gear position (i.e., the reverse gear position).

[0103] Step 706: When it is detected that the gear lever is subjected to a continuous thrust, the vibration intensity generated by the vibration device is increased.

[0104] Specifically, the vehicle control system can detect whether the gear lever 2 is continuously pushed through the sensor. When the gear lever 2 is already in the R gear position (i.e., the reverse gear position), the vehicle control system detects through the sensor that the gear lever 2 is continuously pushed, and then controls the vibration intensity generated by the vibration device 5 to be strengthened. Furthermore, according to the duration of continuous thrust application or the magnitude of thrust application, different levels of vibration intensity are set, that is, the longer the duration of continuous thrust application, the greater the vibration intensity, or the greater the continuous thrust application, the greater the vibration intensity. Through this technical solution, the driver can be prompted that the gear lever 2 is already in the R gear position (i.e., the reverse gear position), and is stabilized in the R gear position (i.e., the reverse gear position) under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 and cannot be moved, and the driver is prompted not to forcefully push the gear lever 2.

[0105] Further, after executing step 702, step 703 and step 704 may be executed simultaneously, or step 703 may be executed first and then step 704, or step 704 may be executed first and then step 703, and there is no limitation here.

[0106] Further, in this embodiment, step 702 may not be executed before step 703 is executed, that is, after step 701 is executed, step 703 is directly executed, that is, the execution order of steps 701→703→705 is the same as Figure 5 The steps of the vehicle gear shifting control method provided are the same and will not be repeated here.

[0107] By adopting the vehicle gear shifting control method provided by this embodiment, when reversing is required in some emergency situations, the driver can press the first button 4, and the first electromagnetic force device 3 generates a magnetic force. When the driver quickly moves the gear lever 2 to the R gear position (i.e., the reverse gear position) of the transmission mechanism, the gear lever 2 cannot be moved further under the attraction of the magnetic force generated by the first electromagnetic force device 3, so that the driver can quickly and accurately position the gear lever 2 in the R gear position (i.e., the reverse gear position) in an emergency, and will not be unable to accurately position the gear 2 in the R gear position (i.e., the reverse gear position) in a very short time due to excessive force, too fast operating speed or tension, thereby buying time for the driver and passengers to avoid danger.

[0108] See also Figure 8 , Figure 8 A schematic diagram of another vehicle gear shift control method provided by an embodiment of the present invention, wherein the method is applied to Figure 1-4 The specific structure of the vehicle gear-engaging device is as described above and will not be described in detail here. The method comprises the following steps:

[0109] Step 801, determine that the first button is pressed, and execute step 802;

[0110] Specifically, when the driver presses the first button 4 , the vehicle control system may detect that the first button 4 is pressed through a sensor.

[0111] Step 802, determining that the gear lever is in the reverse gear position of the transmission mechanism, and executing steps 803 and 804;

[0112] Specifically, when the driver presses the first button 4 , the vehicle control system can detect through the sensor that the shift lever 2 is pushed to the R gear position (ie, the reverse gear position).

[0113] In step 803 , the first electromagnetic force device generates magnetic force, and then step 805 is executed.

[0114] Specifically, the vehicle control system detects that the first button 4 is pressed, at which time the two electromagnets of the first electromagnetic force device 3 do not generate magnetic force. When the vehicle control system further detects that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the two electromagnets of the first electromagnetic force device 3 are controlled to generate magnetic force.

[0115] Since the two electromagnets of the electromagnetic force device 3 can generate electromagnetic force in a very short moment after being energized, the electromagnetic force is generated only when the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), which can also ensure that the gear lever 2 is stabilized in the R gear position (i.e., the reverse gear position) in a timely manner. More importantly, when the driver has no intention of shifting to the R gear (reverse gear) and the gear lever 2 is in other gears (P gear, N gear, D gear, M gear), this embodiment can prevent the driver from accidentally pressing the first button 4, which causes the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 to suck the gear lever 2 to the R gear position (i.e., the reverse gear position). In particular, in special circumstances, for example, when the two electromagnets of the first electromagnetic force device 3 in the R gear position (i.e., the reverse gear position) are not properly electromagnetically shielded or the shielding function of the electromagnetic force shielding device 6 fails, the gear lever 2 may be sucked to the R gear position (i.e., the reverse gear position) by the two electromagnets of the first electromagnetic force device 3, thereby affecting the driving safety and controllability.

[0116] Step 805: When the gear lever is located at the reverse gear position of the transmission mechanism, the gear lever cannot move due to the attraction of the magnetic force generated by the first electromagnetic force device.

[0117] Specifically, after the driver presses the first button 4, when the driver pushes the gear lever 2 to the R gear position (i.e., the reverse gear position), under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved.

[0118] Step 807 , when the shift lever is in the reverse gear position of the transmission mechanism, determine that the first button is released, and then execute step 808 .

[0119] Specifically, when the shift lever 2 is in the R position (ie, the reverse position), if the driver releases the first button 4, the vehicle control system can detect through the sensor that the first button 4 is released, ie, the first button is reset.

[0120] Step 808: the first electromagnetic force device stops generating magnetic force.

[0121] Specifically, when the driver releases the first button 4, the vehicle control system can detect that the first button 4 is released through the sensor, that is, the first button is reset, and at this time, the vehicle control system controls the first electromagnetic force device 3 to stop generating magnetic force. By pressing and releasing the first button 4 to control whether the first electromagnetic force device 3 generates magnetic force, the driver can quickly and flexibly control the gear lever 2 to be stabilized in the R gear position (i.e., the reverse gear position) or change to other required gears in time according to the environment in which the vehicle is located.

[0122] In step 804 , the vibration device generates vibration, and then step 806 is executed.

[0123] Specifically, the vehicle control system can detect through the sensor that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), and at this time the vehicle control system controls the vibration device 5 to generate vibration. Since the driver holds the top of the gear lever 2, the driver can feel the vibration at this time, thereby prompting the driver that the gear lever 2 is currently in the R gear position (i.e., the reverse gear position).

[0124] Step 806: When it is detected that the gear lever is subjected to a continuous thrust, the vibration intensity generated by the vibration device is increased.

[0125] Specifically, the vehicle control system can detect whether the gear lever 2 is continuously pushed through the sensor. When the gear lever 2 is already in the R gear position (i.e., the reverse gear position), the vehicle control system detects through the sensor that the gear lever 2 is continuously pushed, and then controls the vibration intensity generated by the vibration device 5 to be strengthened. Furthermore, according to the duration of continuous thrust application or the magnitude of thrust application, different levels of vibration intensity are set, that is, the longer the duration of continuous thrust application, the greater the vibration intensity, or the greater the continuous thrust application, the greater the vibration intensity. Through this technical solution, the driver can be prompted that the gear lever 2 is already in the R gear position (i.e., the reverse gear position), and is stabilized in the R gear position (i.e., the reverse gear position) under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 and cannot be moved, and the driver is prompted not to forcefully push the gear lever 2.

[0126] Further, after executing step 802, step 803 and step 804 may be executed simultaneously, or step 803 may be executed first and then step 804, or step 804 may be executed first and then step 803, and there is no limitation here.

[0127] Further, in this embodiment, step 802 may not be executed before step 803 is executed, that is, after step 801 is executed, step 803 is directly executed, that is, the execution order of steps 801→803→805 is the same as Figure 5 The steps of the vehicle gear shifting control method provided are the same and will not be repeated here.

[0128] By adopting the vehicle gear shifting control method provided by this embodiment, when reversing is required in some emergency situations, the driver can press the first button 4, and the first electromagnetic force device 3 generates a magnetic force. When the driver quickly moves the gear lever 2 to the R gear position (i.e., the reverse gear position) of the transmission mechanism, the gear lever 2 cannot be moved further under the attraction of the magnetic force generated by the first electromagnetic force device 3, so that the driver can quickly and accurately position the gear lever 2 in the R gear position (i.e., the reverse gear position) in an emergency, and will not be unable to accurately position the gear 2 in the R gear position (i.e., the reverse gear position) in a very short time due to excessive force, too fast operating speed or tension, thereby buying time for the driver and passengers to avoid danger.

[0129] See also Fig. 9 , Fig. 9 A schematic diagram of another vehicle gear shift control method provided by an embodiment of the present invention, wherein the method is applied to Figure 1-4 The specific structure of the vehicle gear-engaging device is as described above and will not be described in detail here. The method comprises the following steps:

[0130] Step 901, determine that the first button is pressed, and execute step 902;

[0131] Specifically, when the driver presses the first button 4 , the vehicle control system may detect that the first button 4 is pressed through a sensor.

[0132] Step 902, determining that the gear lever is in the reverse gear position of the transmission mechanism, and executing steps 903 and 904;

[0133] Specifically, when the driver presses the first button 4 , the vehicle control system can detect through the sensor that the shift lever 2 is pushed to the R gear position (ie, the reverse gear position).

[0134] In step 903 , the first electromagnetic force device generates magnetic force, and then step 905 is executed.

[0135] Specifically, the vehicle control system detects that the first button 4 is pressed, at which time the two electromagnets of the first electromagnetic force device 3 do not generate magnetic force. When the vehicle control system further detects that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), the two electromagnets of the first electromagnetic force device 3 are controlled to generate magnetic force.

[0136] Since the two electromagnets of the electromagnetic force device 3 can generate electromagnetic force in a very short moment after being energized, the electromagnetic force is generated only when the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), which can also ensure that the gear lever 2 is stabilized in the R gear position (i.e., the reverse gear position) in a timely manner. More importantly, when the driver has no intention of shifting to the R gear (reverse gear) and the gear lever 2 is in other gears (P gear, N gear, D gear, M gear), this embodiment can prevent the driver from accidentally pressing the first button 4, which causes the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 to suck the gear lever 2 to the R gear position (i.e., the reverse gear position). In particular, in special circumstances, for example, when the two electromagnets of the first electromagnetic force device 3 in the R gear position (i.e., the reverse gear position) are not properly electromagnetically shielded or the shielding function of the electromagnetic force shielding device 6 fails, the gear lever 2 may be sucked to the R gear position (i.e., the reverse gear position) by the two electromagnets of the first electromagnetic force device 3, thereby affecting the driving safety and controllability.

[0137] Step 905: When the gear lever is located at the reverse gear position of the transmission mechanism, the gear lever cannot move due to the attraction of the magnetic force generated by the first electromagnetic force device.

[0138] Specifically, after the driver presses the first button 4, when the driver pushes the gear lever 2 to the R gear position (i.e., the reverse gear position), under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) and cannot be moved.

[0139] Step 907 , when the shift lever is in the reverse gear position of the transmission mechanism, determine that the first button is released, and then execute step 908 .

[0140] Specifically, when the shift lever 2 is in the R position (ie, the reverse position), if the driver releases the first button 4, the vehicle control system can detect through the sensor that the first button 4 is released, ie, the first button is reset.

[0141] Step 908: the first electromagnetic force device continues to generate magnetic force, and then steps 909 and 910 are executed.

[0142] Specifically, when the driver releases the first button 4, the vehicle control system can detect that the first button 4 is released through the sensor, that is, the first button is reset, and at this time the vehicle control system controls the first electromagnetic force device 3 to continue to generate magnetic force. Through the technical solution provided by this embodiment, the gear lever 2 can be stabilized in the R gear position (i.e., the reverse gear position) without the driver continuously pressing the first button 4.

[0143] Step 909: After a first preset time period, the first electromagnetic force device stops generating magnetic force.

[0144] Specifically, when the driver releases the first button 4, the vehicle control system can detect through the sensor that the first button 4 is released, that is, the first button is reset. At this time, the vehicle control system starts timing and determines whether a first preset time period has passed, for example, 5 seconds. After 5 seconds, the first electromagnetic force device 3 is controlled to stop generating magnetic force.

[0145] Step 910: When it is detected that the first button is pressed twice in succession within a second preset time period, the first electromagnetic force device stops generating magnetic force.

[0146] Specifically, when the driver releases the first button 4, the vehicle control system can detect through the sensor that the first button 4 is released, that is, the first button is reset. At this time, the vehicle control system controls the first electromagnetic force device 3 to continue to generate magnetic force. After that, when the vehicle control system detects that the time interval between two consecutive presses of the first button 4 does not exceed a second preset time period, for example, 0.5 seconds, the vehicle control system regards the two consecutive presses of the first button 4 as a valid double-click command of the first button 4, and the vehicle control system controls the first electromagnetic force device 3 to stop generating magnetic force.

[0147] It should be noted that there is no sequential relationship between step 909 and step 910, that is, the execution order between the two is not interdependent, but can be executed independently. For example, within the first preset time period (for example, within 5 seconds), if it is detected that the first button 4 is pressed twice with an interval of the second preset time period (for example, 0.5 seconds), then even if the first preset time period (for example, 5 seconds) has not arrived, the vehicle control system will control the first electromagnetic force device 3 to stop generating magnetic force. The technical solution provided by this embodiment can prevent the driver from accidentally pushing the gear lever 2 to other gears (P gear, N gear, D gear, M gear) due to nervous release of the first button 4 in an emergency, and can also provide the driver with the release of the magnetic attraction of the gear lever 2 before the first preset time period arrives, so that the driver can flexibly change the gear as needed.

[0148] In step 904 , the vibration device generates vibration, and then step 906 is executed.

[0149] Specifically, the vehicle control system can detect through the sensor that the gear lever 2 is pushed to the R gear position (i.e., the reverse gear position), and at this time the vehicle control system controls the vibration device 5 to generate vibration. Since the driver holds the top of the gear lever 2, the driver can feel the vibration at this time, thereby prompting the driver that the gear lever 2 is currently in the R gear position (i.e., the reverse gear position).

[0150] Step 906: When it is detected that the gear lever is subjected to a continuous thrust, the vibration intensity generated by the vibration device is increased.

[0151] Specifically, the vehicle control system can detect whether the gear lever 2 is continuously pushed through the sensor. When the gear lever 2 is already in the R gear position (i.e., the reverse gear position), the vehicle control system detects through the sensor that the gear lever 2 is continuously pushed, and then controls the vibration intensity generated by the vibration device 5 to be strengthened. Furthermore, according to the duration of continuous thrust application or the magnitude of thrust application, different levels of vibration intensity are set, that is, the longer the duration of continuous thrust application, the greater the vibration intensity, or the greater the continuous thrust application, the greater the vibration intensity. Through this technical solution, the driver can be prompted that the gear lever 2 is already in the R gear position (i.e., the reverse gear position), and is stabilized in the R gear position (i.e., the reverse gear position) under the attraction of the electromagnetic force generated by the two electromagnets of the first electromagnetic force device 3 and cannot be moved, and the driver is prompted not to forcefully push the gear lever 2.

[0152] Further, after executing step 902, step 903 and step 904 may be executed simultaneously, or step 903 may be executed first and then step 904, or step 904 may be executed first and then step 903, and there is no limitation here.

[0153] Further, in this embodiment, step 902 may not be executed before step 903 is executed, that is, after step 901 is executed, step 903 is directly executed, that is, the execution order of steps 901→903→905 is the same as Figure 5 The steps of the vehicle gear shifting control method provided are the same and will not be repeated here.

[0154] By adopting the vehicle gear shifting control method provided by this embodiment, when reversing is required in some emergency situations, the driver can press the first button 4, and the first electromagnetic force device 3 generates a magnetic force. When the driver quickly moves the gear lever 2 to the R gear position (i.e., the reverse gear position) of the transmission mechanism, the gear lever 2 cannot be moved further under the attraction of the magnetic force generated by the first electromagnetic force device 3, so that the driver can quickly and accurately position the gear lever 2 in the R gear position (i.e., the reverse gear position) in an emergency, and will not be unable to accurately position the gear 2 in the R gear position (i.e., the reverse gear position) in a very short time due to excessive force, too fast operating speed or tension, thereby buying time for the driver and passengers to avoid danger.
