Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobiles, in particular to a coordinate information confirmation method based on an asymmetric shift hub and the asymmetric shift hub. BACKGROUND

[0002] In the field of mechanical engineering, especially in the field of vehicle engineering and transmission, the design and optimization of shift mechanisms is an important research direction. The quality of the shift mechanism directly affects the driving experience of the vehicle and the efficiency of the transmission system. Among them, the dog clutch, as a commonly used shift mechanism, is widely used in various DHD vehicles due to its convenient control, long service life, and low cost.

[0003] However, in the shift process of the dog clutch, especially in the stationary state of the vehicle, the position of the shift hub needs to be determined in advance to complete the engagement of the forward gear. In the prior art, one is to determine the position of the shift hub by arranging a position sensor. However, this method has a high cost and it is not easy to arrange the sensor. The second is to continuously apply force to the gear direction during shifting until the shift is successful. This method does not require the installation of a sensor, but the noise (NVH) during the shift process is poor, and the jerk during the shift is strong. The third is to use a call motor to assist the forward gear. This method requires high pressure before self-learning, which has certain safety hazards.

[0004] Therefore, the existing solutions either require additional sensors, which have high costs, or have strong noise and jerk during the shift process, which has poor user experience, or require the use of a motor to assist, which has certain safety hazards. SUMMARY

[0005] Therefore, the present application provides a coordinate information confirmation method based on an asymmetric shift hub and the asymmetric shift hub to solve the technical problems of high cost, strong noise and jerk, and safety hazards in the background art when the position of the shift hub is confirmed in the stationary state of the vehicle.

[0006] The first aspect of the present application provides a coordinate information confirmation method based on an asymmetric shift hub. The confirmation method is applied to a vehicle with a shift hub.

[0016] The data of the coordinate information in the second gear sticking point is less than the data of the coordinate information in the second gear stop point.

[0017] Further, in the step of respectively confirming a plurality of preset stroke parameters between the stop points, between the sticking points, and between each of the stop points and each of the sticking points, it includes:

[0020] constructing a third preset stroke parameter according to the coordinate information in the first gear stop point and the coordinate information in the second gear sticking point;

[0021] According to the coordinate information in the first gear stop point and the coordinate information in the second gear stop point, a fourth preset stroke parameter is constructed.

[0022] Further, the stroke parameter data in the first preset stroke parameter, the stroke parameter data in the second preset stroke parameter, the stroke parameter data in the third preset stroke parameter, and the stroke parameter data in the fourth preset stroke parameter are all different.

[0023] Further, in the step of comparing the actual stroke parameter with a plurality of preset stroke parameters to confirm the coordinate information of the shift hub,

[0024] comparing the actual stroke parameter with the first preset stroke parameter, the second preset stroke parameter, the third preset stroke parameter, and the fourth preset stroke parameter;

[0025] when it is determined that the actual stroke parameter corresponds to one of the first preset stroke parameter, the second preset stroke parameter, the third preset stroke parameter, and the fourth preset stroke parameter, the coordinate information of the shift hub is confirmed.

[0026] Further, after the step of confirming the coordinate information of the shift hub, it further includes:

[0027] when the actual stroke parameter does not correspond to any one of the first preset stroke parameter, the second preset stroke parameter, the third preset stroke parameter, and the fourth preset stroke parameter;

[0046] First Embodiment

[0047] Please see Figure 1 The figure shows a coordinate information confirmation method based on an asymmetric shift hub in the first embodiment of the present invention. The confirmation method is applied to a vehicle with a shift hub. The groove in the shift hub is asymmetrically arranged, so that the preset stroke parameters between the multiple dead points and multiple stuck points formed by the shift hub during operation are different. It should be noted that, in this embodiment, the stuck point is the dead point position of the shift hub during operation, indicating that the shift hub must not pass. The stuck point is the stuck position of the shift hub during operation, indicating that the shift hub is stuck when passing, but can pass.

[0048] Specifically, the confirmation methods include:

[0049] S01, obtain the coordinate information of each stop point and the coordinate information of each jamming point.

[0050] It should be noted that the stop point and the stuck point are actual states of the shift hub in operation.

[0051] S02, the coordinate information of each stop point and the coordinate information of each stuck point are analyzed to respectively confirm a plurality of preset travel parameters between the plurality of stop points, between the plurality of stuck points, between each stop point and each stuck point.

[0052] It should be noted that in step S02, in the step of respectively confirming a plurality of preset travel parameters between the plurality of stop points, between the plurality of stuck points, between each stop point and each stuck point, the plurality of stop points include a first-gear stop point and a second-gear stop point, and the plurality of stuck points include a first-gear stuck point and a second-gear stuck point.

[0053] In some preferred embodiments, the first-gear stop point and the second-gear stop point are not limited to the number of stop points, and the first-gear stuck point and the second-gear stuck point are not limited to the number of stuck points.

[0054] In addition, in the step of respectively confirming a plurality of preset travel parameters between the plurality of stop points, between the plurality of stuck points, between each stop point and each stuck point, the data of the coordinate information in the first-gear stop point is less than the data of the coordinate information in the first-gear stuck point; the data of the coordinate information in the first-gear stuck point is less than the data of the coordinate information in the second-gear stuck point; and the data of the coordinate information in the second-gear stuck point is less than the data of the coordinate information in the second-gear stop point.

[0055] That is, in step S02, the plurality of preset travel parameters are respectively:

[0056] a first preset travel parameter is constructed according to the coordinate information in the first-gear stuck point and the coordinate information in the second-gear stuck point;

[0057] a second preset travel parameter is constructed according to the coordinate information in the first-gear stuck point and the coordinate information in the second-gear stop point;

[0058] a third preset travel parameter is constructed according to the coordinate information in the first-gear stop point and the coordinate information in the second-gear stuck point;

[0059] a fourth preset travel parameter is constructed according to the coordinate information in the first-gear stop point and the coordinate information in the second-gear stop point;

[0060] Among them, the travel parameter data in the first preset travel parameter, the travel parameter data in the second preset travel parameter, the travel parameter data in the third preset travel parameter and the travel parameter data in the fourth preset travel parameter are all different.

[0061] For the convenience of understanding the case, please refer to Figure 2As shown, p1 is the first gear stop point, p2 is the first gear jam point, p3 is the second gear stop point, and p4 is the second gear jam point. According to the coordinate information of p1, p2, p3, and p4, the preset forming parameters of the shift hub can be obtained, which are d1, d2, d3, and d4, respectively. d1, d2, d3, and d4 are not equal.

[0062] S03, controlling the shift hub to perform at least two operations, so that the shift hub passes through the stop point or the jam point in the two operations, and at least two operation coordinate information corresponding to the stop point or the jam point is formed, respectively, wherein the directions of the two operations are opposite.

[0063] Specifically, when the vehicle is in a stationary state, the shift hub is controlled to perform two operations, which can be forward rotation and reverse rotation of the shift hub, respectively. For example, when the first operation is forward rotation, the shift hub touches the first gear jam point during the operation, and the first operation coordinate information, that is, the coordinate information of p2, is recorded. When the second operation is reverse rotation, the shift hub touches the second gear stop point during the operation, and the second operation coordinate information, that is, the coordinate information of p3, is recorded.

[0064] S04, confirming the actual stroke parameter of the shift hub according to the at least two operation coordinate information.

[0065] According to the coordinate information of p2 and p3, the actual stroke parameter of the shift hub, that is, the first preset stroke parameter d1, can be determined.

[0066] S05, comparing the actual stroke parameter with the plurality of preset stroke parameters to confirm the coordinate information of the shift hub.

[0067] According to S04, when the actual stroke parameter is d1, the actual stroke parameter corresponds to the first preset stroke parameter, and the coordinate information of the shift hub when the vehicle is in a stationary state is determined.

[0068] In addition, in order to facilitate understanding of the difference between the asymmetric shift hub in the embodiment and the shift hub in the prior art, please refer to Figure 3 As shown, it should be noted that the groove body of the shift hub in the prior art is designed symmetrically, and the shift hub in the prior art also has p1 as the first gear stop point, p2 as the first gear jam point, p3 as the second gear stop point, and p4 as the second gear jam point. Correspondingly, d1 is the first preset stroke parameter, d2 is the second preset stroke parameter, d3 is the third preset stroke parameter, and d4 is the fourth preset stroke parameter.

[0069] Please refer to Figure 4As shown, the black thick solid line represents the state of the asymmetric shift hub in the present embodiment when d2 is the second preset stroke parameter. Since the groove body in the prior art shift hub is symmetrically designed, then

[0070] d1≠d2≠d3≠d4

[0071] However, the groove body in the shift hub of the present application is asymmetrically designed, then

[0072] d1≠d2≠d3≠d4

[0073] That is, by changing the design of the groove body in the shift hub, the corresponding preset stroke parameters in the actual operating state of the shift hub are different, thereby making the position of the asymmetric shift hub more reliable and stable.

[0074] In summary, the coordinate information confirmation method based on the asymmetric shift hub shown in the present embodiment has at least the following beneficial effects compared with the prior art method of determining the position of the shift hub:

[0075] In the coordinate information confirmation method based on the asymmetric shift hub provided by the present application, the confirmation method is applied to a vehicle with a shift hub, and the groove body in the shift hub is asymmetrically arranged. By changing the design of the groove body in the shift hub, the preset stroke parameters between the multiple stop points and the multiple stuck points formed by the shift hub during operation are different, i.e. the confirmation method comprises: first, obtaining the coordinate information of each stop point and the coordinate information of each stuck point; then, analyzing the coordinate information of each stop point and the coordinate information of each stuck point to confirm the multiple preset stroke parameters between the multiple stop points, between the multiple stuck points, and between each stop point and each stuck point, respectively; controlling the shift hub to operate at least twice so that the shift hub forms at least two operating coordinate information corresponding to the stop points or the stuck points when passing through the stop points or the stuck points during the two operations, wherein the directions of the two operations are opposite; confirming the actual stroke parameters of the shift hub according to the at least two operating coordinate information; and finally comparing the actual stroke parameters with the multiple preset stroke parameters to confirm the coordinate information of the shift hub. Firstly, by adopting the design of the asymmetric shift hub, the position of the shift hub can be confirmed without the need to install sensors or call for motor assistance, and by the different preset stroke parameters, the design of the shift mechanism is simpler and the maintenance is more convenient, thereby reducing the cost. Secondly, the noise (NVH) during the shifting process is smaller and the jerk is weaker, thereby improving the driving experience of the user. Thirdly, the present application does not need to be under high pressure during self-learning, avoiding the safety hazards existing in the prior art which needs to be under high pressure. At the same time, the confirmation of the coordinate information of the shift hub can be completed within 3 seconds, which is fast and efficient, further improving the safety.

[0076] Second embodiment

[0077] In another aspect, the present invention also provides a method for confirming coordinate information based on an asymmetric shift hub. The steps of the coordinate information confirmation method in this embodiment are the same as those in the first embodiment. However, in S05 of this embodiment, after the step of comparing the actual stroke parameters with multiple preset stroke parameters to confirm the coordinate information of the shift hub, the method further includes:

[0078] When the actual travel parameters do not correspond to any of the first preset travel parameters, the second preset travel parameters, the third preset travel parameters, and the fourth preset travel parameters;

[0079] The shift hub is controlled to run twice more, so that when the shift hub passes the dead point or jamming point during the two runs, at least two running coordinate information corresponding to the dead point or jamming point are generated again, and the two runs are in opposite directions.

[0080] Confirm the actual stroke parameters of the shift hub based on at least two operating coordinate information;

[0081] The actual stroke parameters are compared with multiple preset stroke parameters to confirm the coordinate information of the shift hub.

[0082] In other words, by controlling the shift hub to run at least twice more, the shift hub can acquire two more running coordinates during operation. The position of the shift hub can then be confirmed based on these two running coordinates, thereby further improving the reliability of the shift hub position confirmation.

[0086] To facilitate understanding that the tanks in this embodiment are asymmetrically arranged, please refer to [link / reference]. Figure 6 The image shows a symmetrical shift hub in the prior art. The symmetrical shift hub also includes a shift hub body 100 and a groove provided in the shift hub body. Specifically, the groove includes a first sub-groove 110 and a second sub-groove 120, and the first sub-groove 110 and the second sub-groove 120 are symmetrically arranged.
