Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle intelligent driving, and in particular to a driving posture monitoring method and device based on handlebar contact matrix sensing. Background Art

[0002] The handlebars of electric vehicles are the main regulating device for the power output of electric vehicles. Currently, there is no relevant safety mechanism on electric vehicles. Power can be output by turning the handlebars. If a child unconsciously plays with the handlebars and accidentally turns the handlebars, the vehicle will fly out of control because the child has no ability to control the vehicle, which may cause dangerous accidents to people and vehicles.

[0003] If an adult does not fully grasp the handlebars, but only slightly grasps or pinches them to turn them, the vehicle will have sufficient power but the person cannot maintain balance well, which can easily lead to dangerous accidents.

[0004] When the vehicle is driving normally, it is most stable for the driver to control the vehicle with both hands. Taking one or both hands off the handlebars are dangerous driving behaviors, which can easily lead to loss of control of the vehicle and cause dangerous accidents. Summary of the invention

[0005] In view of the above problems and technical requirements, the inventors have proposed a driving posture monitoring method and device based on handlebar contact matrix sensing. The technical solution of the present invention is as follows:

[0006] In a first aspect, the present application provides a driving posture monitoring method based on handlebar contact matrix sensing, comprising the following steps:

[0007] Based on the contact matrix sensing module wrapped on the left and right handlebars, the contact scanning pattern formed by the driver's hand contacting the left and right handlebars is obtained in real time;

[0008] According to the contact point scanning pattern of the left handlebar and the reference pattern of the left handlebar, and the contact point scanning pattern of the right handlebar and the reference pattern of the right handlebar, whether the grip postures of the left and right handlebars meet the specifications is determined, and the vehicle power output is adjusted accordingly;

[0009] The reference pattern is a minimum continuous effective contact matrix pattern formed on the contact matrix sensing module when simulating a normal adult grip.

[0010] A further technical solution is to determine whether the grip postures of the left and right handlebars meet the specification according to the contact scanning pattern of the left handlebar and the reference pattern of the left handlebar, and the contact scanning pattern of the right handlebar and the reference pattern of the right handlebar, including:

[0011] The contact scanning patterns and reference patterns of the left and right handlebars are converted into logic matrix forms, which are recorded as scanning logic matrix and reference logic matrix respectively, wherein the elements in the scanning logic matrix correspond one-to-one to the contacts of the contact matrix sensing module, and the element values ​​in the scanning logic matrix and the reference logic matrix are assigned according to whether the contacts are valid or not;

[0012] The scanning logic matrix of the left handlebar and the reference logic matrix of the left handlebar, and the scanning logic matrix of the right handlebar and the reference logic matrix of the right handlebar are respectively fitted and calculated;

[0013] Determine whether the grip postures of the left and right handlebars meet the specifications based on the fitting calculation results.

[0014] A further technical solution is to perform fitting calculation on the scan logic matrix of the left handlebar and the reference logic matrix of the left handlebar, which is the same as the method of fitting calculation on the scan logic matrix of the right handlebar and the reference logic matrix of the right handlebar. The fitting calculation method for the handlebar on either side includes:

[0015] In the scanning logic matrix, a moving matrix with the same size as the reference logic matrix is ​​searched cyclically until all elements of the scanning logic matrix are traversed;

[0016] After each moving matrix is ​​determined, a logical AND operation is performed on the moving matrix and the elements in the reference logic matrix according to corresponding positions to obtain a fitting matrix of the same size as the reference logic matrix;

[0017] Add all elements of the fitting matrix to obtain the fitting calculation result;

[0018] Among them, if the contact is valid, the element value in the scan logic matrix and the reference logic matrix is ​​1, otherwise it is 0.

[0019] A further technical solution is to determine whether the grip postures of the left and right handlebars meet the specification according to the fitting calculation results, including:

[0020] If the fitting calculation result is equal to the sum S of all elements of the reference logic matrix, or the fitting calculation result is equal to S-1, or the fitting calculation result is equal to S-2, and there are no two adjacent invalid points in the fitting matrix, then the grip posture of the corresponding side handlebar is considered to meet the specifications;

[0021] If the fitting calculation result is equal to S-2, and there are two adjacent invalid points in the fitting matrix, or the fitting calculation result is between greater than or equal to 0 and less than S-2, it is considered that the grip posture of the corresponding side handlebar does not meet the specification;

[0022] The fitting matrix is ​​a matrix having the same size as the reference logic matrix obtained by fitting the scanning logic matrix of the corresponding side handlebar with the reference logic matrix.

[0023] A further technical solution is that a method for identifying whether there are two adjacent invalid points in the fitting matrix includes:

[0024] The invalid points in the fitting matrix that are in the same position as the invalid points in the reference logic matrix are inverted to obtain the setting matrix Temp[k 2 ][n 2 ], where k 2 is the number of matrix rows, n 2 is the number of matrix columns;

[0025] Perform a logical OR operation on adjacent row elements in the setting matrix according to corresponding positions in the same column, and add up the operation results to obtain the row result;

[0026] Perform logical OR operation on adjacent column elements in the setting matrix according to corresponding positions in the same row, and add up the operation results to obtain the column result;

[0027] If the sum of the row result and the column result is equal to (n 2 -1)×k 2 +(k 2 -1)×n 2 , it is considered that there are no two adjacent invalid points in the fitting matrix;

[0028] If the sum of the row result and the column result is equal to (n 2 -1)×k 2 +(k 2 -1)×n 2 -1, it is considered that there are two adjacent invalid points in the fitting matrix.

[0029] A further technical solution is that the fitting calculation method for the handlebar on either side further includes:

[0030] According to the size of the reference logic matrix, the scan logic matrix is ​​expanded by m rows along the row direction, and the elements of the expanded rows correspond to the same elements of the first m rows of the scan logic matrix;

[0031] In the expanded scanning logic matrix, a moving matrix with the same size as the reference logic matrix is ​​cyclically searched so that the moving matrix corresponds to a complete reference logic matrix.

[0032] A further technical solution is to adjust the vehicle power output, including:

[0033] When the grip posture of the right handlebar does not meet the standard, the power output is stopped;

[0034] When the grip posture of the right handlebar meets the specifications, power output is allowed; on this basis, if the grip posture of the left handlebar meets the specifications, normal power output is allowed and the maximum vehicle speed is not restricted; if the grip posture of the left handlebar does not meet the specifications, the power output and the maximum vehicle speed are restricted.

[0035] In a second aspect, the present application provides a driving posture monitoring device based on handlebar contact matrix sensing, comprising:

[0036] The contact matrix sensing module wrapped around the left and right handlebars is used to sense the contact between the driver's hands and the handlebars in real time, forming a contact scanning pattern of the left and right handlebars;

[0037] The left and right contact point sensing processors are connected to each contact point in the contact point matrix sensing module on the corresponding side handlebars, and are used to convert the contact point scanning patterns of the left and right handlebars into a logic matrix form;

[0038] The central control module is connected to the left and right touch sensing processors. The central control module pre-stores reference patterns of the left and right handlebars. The reference pattern is a minimum continuous effective contact matrix pattern formed on the touch matrix sensing module when simulating a normal adult grip;

[0039] The central control module is used to determine whether the grip postures of the left and right handlebars meet the specifications based on the contact scanning pattern of the left handlebar and the reference pattern of the left handlebar, as well as the contact scanning pattern of the right handlebar and the reference pattern of the right handlebar, and adjust the vehicle power output accordingly.

[0040] A further technical solution is that the device also includes a Bluetooth module connected to the central control module, which is used to receive the reference graphics of the left and right handlebars and the corresponding reference logic matrix customized by the user.

[0041] A further technical solution is that the contact matrix sensing module is implemented based on a piezoresistive or capacitive sensor contact matrix.

[0042] The beneficial technical effects of the present invention are:

[0043] Through the contact matrix sensing module installed on the left and right handlebars, the contact scanning pattern formed by the driver's hand contacting the handlebar can be obtained in real time, and calculated with the reference pattern of the corresponding side handlebar through a preset algorithm, that is, the pattern is first converted into a logic matrix form, and then the scanning logic matrix of the corresponding side handlebar is fitted with the reference logic matrix. According to the fitting calculation results, it can be identified that the grip posture does not meet the safety regulations, such as children's grip, one-hand grip, or both hands off the handlebar, and then combined with the grip posture of the handlebars on both sides, the choice is normal power output, limited power output, or stopped power output.

[0044] Installing this method and device on an electric vehicle can prevent dangerous accidents caused by children turning the handlebars by mistake or by the owner's unconscious or illegal operation; when the owner rides the vehicle with dangerous driving behavior (such as riding with one hand), the power output can be limited, thereby reducing dangerous accidents caused by insufficient control.

[0056] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0057] Please refer to Figure 1 As shown, in one embodiment of the present application, a driving posture monitoring device based on handlebar contact matrix sensing is provided, including left and right contact matrix sensing modules, left and right contact sensing processors, a central control module and a Bluetooth module. Figure 2 , Figure 3As shown, the contact matrix sensing modules 1a and 1b are respectively wrapped on the left and right handlebars, the contacts 101 are independent of each other, and the first row and the last row of contacts are adjacent to each other on the handlebars. The left contact sensing processor is connected to each contact in the left contact matrix sensing module through a data harness, and the right contact sensing processor is connected to each contact in the right contact matrix sensing module through a data harness. Figure 4 The left and right touch sensing processors and the Bluetooth module are connected to the central control module.

[0058] Among them, the contact matrix sensing module can be implemented based on a piezoresistive or capacitive sensor contact matrix, which is used to sense the contact between the driver's hand and the handlebar in real time, forming a contact scanning pattern of the left and right handlebars, such as Figure 5 As shown on the left, the lit contact indicates that it is in contact with the driver's hand. The left and right contact sensing processors are used to convert the contact scanning patterns of the left and right handlebars into a logic matrix form, that is, the capacitance or resistance value of the contact that is in contact will change, and the contact sensing processor will regard the changed contact as a valid contact and assign a value of "1", and the unchanged contact as an invalid contact and assign a value of "0", and finally output the scanning logic matrix of the left and right handlebars, as shown in Figure 1. Figure 5 As shown on the right, the elements in the scan logic matrix correspond one-to-one to the contacts of the contact matrix sensing module.

[0059] The central control module has pre-stored reference patterns for the left and right handlebars. The reference patterns are the minimum continuous effective contact matrix patterns formed on the contact matrix sensing module when simulating the normal grip of an adult. Figure 6 As shown on the left, there are at least three consecutive rows, and each row has at least six consecutive contacts that are valid, and the leftmost column represents the position of the thumb, and at least five consecutive contacts are valid; the reference pattern of the left handlebar is as follows Figure 7 As shown on the left, there are at least three consecutive rows, and each row has at least six consecutive contacts that are valid, and the rightmost column represents the position of the thumb's mouth, and at least five consecutive contacts are valid. Depending on whether the contact is valid or not, each reference pattern has its corresponding reference logic matrix, such as Figure 6 , Figure 7 As shown on the right, they are stored in the central control module.

[0060] Optionally, the car owner can customize the reference graph on his / her end, that is, fine-tune the reference graph provided by the manufacturer according to his / her hand shape, so that the subsequent calculations are more suitable for his / her own situation, such as Figure 6 (1) and (2), Figure 7 (1) and (2) respectively give two kinds of reference graphics A / B for fine-tuning the left and right handlebars. The reference graphics of the left and right handlebars and the corresponding reference logic matrix customized by the user can be uploaded to the central control module through the Bluetooth module for update and storage.

[0061] The central control module is also provided with a driving posture monitoring method based on the handlebar contact matrix sensing, which determines whether the grip postures of the left and right handlebars meet the specification based on the contact scanning pattern of the left handlebar and the reference pattern of the left handlebar, and the contact scanning pattern of the right handlebar and the reference pattern of the right handlebar, and adjusts the vehicle power output accordingly. This method will be described in detail in the following embodiments.

[0062] Please refer to Figure 8 As shown, another embodiment of the present application provides a driving posture monitoring method based on handlebar contact matrix sensing, which specifically includes the following steps:

[0063] Step 1: Based on the contact matrix sensing module wrapped around the left and right handlebars, the contact scanning pattern formed by the driver's hand contacting the left and right handlebars is obtained in real time.

[0064] Step 2: According to the contact scanning pattern of the left handlebar and the reference pattern of the left handlebar, and the contact scanning pattern of the right handlebar and the reference pattern of the right handlebar, determine whether the grip postures of the left and right handlebars meet the specifications, and adjust the vehicle power output accordingly.

[0065] The detailed description of the contact scanning pattern and the reference pattern can be referred to the specific description in the above embodiment, which will not be repeated here. In step 2, according to the contact scanning pattern of the left handlebar and the reference pattern of the left handlebar, the contact scanning pattern of the right handlebar and the reference pattern of the right handlebar, it is determined whether the grip posture of the left and right handlebars meets the specification, which specifically includes:

[0066] Step 2.1: Convert the contact scanning patterns and reference patterns of the left and right handlebars into logic matrix form, which are recorded as scanning logic matrices ScanArr[k 1 ][n 1 ], left handlebar reference logic matrix LeftRefArr[k 2 ][n 2 ] and the right handlebar reference logic matrix RightRefArr[k 2 ][n 2 ], k is the number of matrix rows, and n is the number of matrix columns. The elements in the scanning logic matrix correspond to the contacts of the contact matrix sensing module one by one, and the element values ​​in the scanning logic matrix and the reference logic matrix are assigned according to whether the contact is valid or not. In this embodiment, if the contact is valid, the element values ​​in the scanning logic matrix and the reference logic matrix are 1, otherwise they are 0. Let k 1 =n 1 =8, k 2 =5,n 2 =6.

[0067] Step 2.2: Perform fitting calculations on the scanned logic matrix of the left handlebar and the reference logic matrix of the left handlebar, and on the scanned logic matrix of the right handlebar and the reference logic matrix of the right handlebar, respectively.

[0068] Step 2.3: Determine whether the grip postures of the left and right handlebars meet the specifications based on the fitting calculation results.

[0069] In this embodiment, by converting the contact scanning graph and the reference graph into a logic matrix form and then performing corresponding fitting calculations, compared with graphical processing, numerical calculations are more convenient and have a higher accuracy rate, and will not cause additional calculation burden on the vehicle central control module.

[0070] In step 2.2, the scan logic matrix of the left handlebar is fitted with the reference logic matrix of the left handlebar, which is the same as the method of fitting the scan logic matrix of the right handlebar with the reference logic matrix of the right handlebar. The fitting calculation method for the handlebar on either side specifically includes:

[0071] First, according to the size of the reference logic matrix, the scan logic matrix is ​​expanded by m rows along the row direction, and the elements of the expanded rows correspond to the elements of the first m rows of the scan logic matrix. Fig. 9 As shown, taking the right handlebar scan logic matrix as an example, its original range is Range[A1:H8]. Since it is possible to cross Range[A1:H1] and Range[A8:H8] when holding the handlebar, the continuous valid contacts are divided in the scan logic matrix / graph. For the convenience of subsequent calculations, according to the right handlebar reference logic matrix RightRefArr[5][6], the scan logic matrix ScanArr[8][8] is expanded by 4 rows along the row direction, and Range[A1:H4] and Range[A9:H12] are equal and overlapped, then the continuous valid contacts starting from the Range[A8:H8] row can form a complete graph.

[0072] Secondly, if Fig. 9 As shown, in the expanded scan logic matrix 2, the mobile matrix 201 of the same size as the reference logic matrix is ​​searched cyclically until all elements of the scan logic matrix are traversed. The mobile matrix found in the expanded scan logic matrix can correspond to a complete reference logic matrix. In this embodiment, the loop sequence can be in the order of moving from Range[A1:F5] to Range[C8:H12] in sequence, moving one row or one column each time, moving up to 3 times when the column moves, and up to 8 times when the row moves, and a total of up to 24 times are required to fully cover the expanded scan logic matrix.

[0073] After determining the movement matrix each time, perform a logical AND operation on the elements of the movement matrix and the reference logic matrix according to the corresponding positions to obtain a fitting matrix Fitting[k 2 [n 2 with the same size as the reference logic matrix. Add up all the elements of the fitting matrix to obtain the fitting calculation result Result_Sum. The calculation process is as Fig.10 shown, and it can be obtained that Result_Sum = 18.

[0074] In step 2.3, determine whether the grip postures of the left and right handlebars meet the specifications according to the fitting calculation result. Specifically, it includes: ① When Result_Sum is equal to the sum S of all elements of the reference logic matrix, it means that there is a part in the scanning logic matrix of the corresponding side handlebar that completely coincides with the reference logic matrix, so the fitting passes and the grip posture is normal. ② To prevent overfitting, it is allowed that in the area of Fitting[k 2 [n 2 where the effective point positions are the same as those of the reference logic matrix, there are at most two invalid points compared to the reference logic matrix, and the two invalid points cannot be adjacent. At this time, Result_Sum = S - 1 or S - 2, and the fitting is also determined to pass and the grip posture is normal. ③ When 0 < Result_Sum < S - 2, it means that the coincidence degree between the scanning logic matrix of the corresponding side handlebar and the reference logic matrix is not high, and there may be a situation where a child holds the handlebar or the owner holds the handlebar irregularly, so the fitting fails and the grip posture is abnormal. ④ When Result_Sum = 0, it means that there is no grip behavior on the handlebar, so the fitting fails.

[0075] For the second point, when Result_Sum = S - 2, there may be two adjacent invalid points, and this situation needs to be excluded. As Fig.11 shown, the method for identifying whether there are two adjacent invalid points in the fitting matrix includes: taking the invalid points in Fitting[k 2 [n 2 that have the same positions as the invalid points in the reference logic matrix and taking the inverse (i.e., setting the red 0 to 1) to obtain a set matrix Temp[k 2 [n 2 . Perform a logical OR operation on the adjacent row elements of the set matrix according to the corresponding positions in the same column and accumulate the operation results to obtain the row result Result_Row. That is, in this embodiment, the adjacent row elements temp(k 2 ,6) = {Temp[k 2 [0], Temp[k 2 [1], Temp[k 2 [2], Temp[k 2 [3], Temp[k 2][4],Temp[k 2 ][5]}, then:

[0076]

[0077] A logical OR operation is performed on the adjacent column elements in the bit matrix according to the corresponding positions in the same row, and the operation results are accumulated and summed to obtain the column result Result_Cols. That is, in this embodiment, the adjacent column elements temp(5,n 2 )={Temp[0][n 2 ],Temp[1][n 2 ],Temp[2][n 2 ],Temp[3][n 2 ],Temp[4][n 2 ]},but:

[0078]

[0079] If Result_Row+Result_Cols=(n 2 -1)×k 2 +(k 2 -1)×n 2 , it is considered that there are no two adjacent invalid points in the fitting matrix; if Result_Row+Result_Cols=(n 2 -1)×k 2 +(k 2 -1)×n 2 -1, it is considered that there are two adjacent invalid points in the fitting matrix. In this embodiment, the sum of all elements of the reference logic matrix S = 20, so Result_Sum = S-2 = 18 meets the second point, and it is necessary to further identify whether there are two adjacent invalid points. Fig.11 The calculation steps shown in the figure can be used to obtain Result_Row+Result_Cols=24+25=49, which is exactly the same as k 2 =5,n 2 =6, so there are no two adjacent invalid points in the fitting matrix given in this example, for example, the positions of the blue 0s in the figure are not adjacent.

[0080] The gripping behavior when the fitting is passed is collectively referred to as the standard gripping posture, and the gripping behavior when the fitting is not passed or the non-gripping behavior is collectively referred to as the non-standard gripping posture. Combining the contents of points ① to ④, it can be concluded that:

[0081] (1) If the fitting calculation result is equal to the sum S of all elements of the reference logic matrix, or the fitting calculation result is equal to S-1, or the fitting calculation result is equal to S-2, and there are no two adjacent invalid points in the fitting matrix, then the grip posture of the corresponding side handlebar is considered to meet the specifications. (2) If the fitting calculation result is equal to S-2, and there are two adjacent invalid points in the fitting matrix, or the fitting calculation result is between greater than or equal to 0 and less than S-2, then the grip posture of the corresponding side handlebar is considered to not meet the specifications.

[0082] Finally, the method for adjusting the vehicle power output according to the grip posture of the left and right handlebars includes: when the grip posture of the right handlebar does not meet the specification, the vehicle power output is stopped. When the grip posture of the right handlebar meets the specification, the vehicle power output is allowed; on this basis, if the grip posture of the left handlebar meets the specification, the power output is allowed to be normal, and the maximum vehicle speed is not limited; if the grip posture of the left handlebar does not meet the specification, the power output and the maximum vehicle speed are limited to 15km / h.

[0083] The above is only a preferred embodiment of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
