Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
For a better understanding of the embodiments of the present invention, the vehicle identification code and the input keypad related to the embodiments of the present invention will be described below.
Vehicle Identification Number (VIN), also called Vehicle Identification code and Vehicle Identification Number, is a code for indicating the identity of a Vehicle. The VIN code of the automobile is the only and accurate automobile 'ID card' for identifying the automobile all over the world, and the VIN code is accompanied with the whole process from the registration, insurance, annual inspection, maintenance, repair to recovery and scrapping of the automobile. The history of automotive VIN dates back to 1949, but before 1981, the standards have been in transition. For example, the VIN code of the automobile in 1965-1969 has 9 bits, and 10 bits are adopted after the production exceeds 100 ten thousand in the same year; the automobile VIN code in 1970 and 1980 is fixed to 10 bits; the current automotive VIN code began in 1981.
The current 17-digit VIN code is specified by the Society of Automotive Engineers (SAE), as shown in FIG. 1. The VIN code of the automobile can be divided into 3 parts, and 1-3 parts are World manufacturing identity codes (WMI); 4-9 bits are Vehicle Description Section (VDS); positions 10-17 are the Vehicle Indicator Section (VIS).
Specifically, the first place in WMI may be used to represent a production country code (geographical region), for example, a-H for africa, J-R for asia, S-Z for europe, 6-7 for oceania, 1-5 north america, 8, 9, and 0 for south america, specifically, as shown in table 1, with each country being represented by a corresponding character code.
TABLE 1
| Character code | State of the country | Character code | State of the country | Character code | State of the |
| 1 | USA | J | Japanese | S | Great Britain |
| 2 | Canada | K | Korea | T | Switzerland |

| 4 | USA | W | Germany | ||
| 6 | Australia | Y | Sweden | ||
| 9 | Brazil rubber | Z | Italy (chemical vapor deposition) |
The second bit in WMI is used to represent the car manufacturer code, where G is used to represent all brands belonging to a general car: buick, Cadillac, Chevrolet, Oldsmobile, Pontiac, Saturn. As shown in table 2, different car manufacturers are represented by different character codes.
TABLE 2
Specifically, the 4-8 bits in the VDS portion of the vehicle VIN code are used to represent vehicle characteristics. Wherein, 4-5 bits are used for representing the brand and series codes of the vehicle type; bit 6 represents a body type code; bit 7 is used to represent the passenger safety protection device code; bit 8 is used to represent the engine model code. The 9 th bit in the VDS is a check bit used for checking the vehicle VIN code according to a check algorithm, and the check bit can be represented by any one of numbers 0 to 9 or a letter "X".
Specifically, the 10 th digit in VIS in the VIN code of the automobile represents a model year, which is not necessarily the actual production year of the automobile, but generally differs from the actual production year by no more than 1 year. The 11 th bit in VIS represents the assembly plant, i.e. different assembly plants are represented by different codes. Positions 12-17 in VIS represent the delivery sequence number of the automobile, and are written by automobile manufacturers. Where the last four bits must be numbers.
It should be noted that the characters in the VIN code of the car cannot be I, O or Q (letters I, O and Q are similar to 1 and 0, and are not used), and as can be seen from the above description of the VIN code of the car, each bit in the VIN code has a specific meaning.
As shown in fig. 2, a general input keyboard is provided, on which all characters required for general input are included. If the universal input keyboard is invoked when the VIN code is entered, an input error may result because the input keyboard contains characters that are not likely to be included in the VIN code, such as the characters I, O and Q.
In order to solve the above problem, an embodiment of the present invention provides an input control method, which can determine possible characters of a current input bit according to a coding rule of a VIN code, adjust an input keyboard according to the character set, and perform instructive input when a maintenance worker or a vehicle owner inputs a VIN, thereby reducing an error probability when the VIN code is input.
An input control method, an input control device, and a computer-readable storage medium according to embodiments of the present invention are further described below.
Referring to fig. 3, fig. 3 is a schematic flowchart of an input control method according to an embodiment of the present invention. As shown in FIG. 3, the input control method includes steps 301 to 303, wherein:
301. and determining the current key-in position and the key-in character according to the vehicle identification code key-in instruction.
The input control device determines the current key-in position and the key-in character according to the vehicle identification code key-in instruction.
It should be noted that the vehicle identification code entering instruction includes a start input instruction for the vehicle identification code, a wake-up instruction for the vehicle identification code input interface, or a key-in instruction for a previous key-in position of a current key-in position of the vehicle identification code.
The current key-in position refers to a position to be currently keyed in on an input keyboard of the vehicle identification code; the typed characters of the vehicle identification code refer to characters already input on an input keyboard of the vehicle identification code, and it should be noted that the typed characters of the vehicle identification code can be empty or one or more digits; it is understood that the number of digits of the typed character of the vehicle identification code is at most 17 digits.
Further, the number of digits of the current key-in position of the vehicle identification code may be determined according to the number of characters of the key-in character, and specifically, the number of digits of the current key-in position is the number of characters of the key-in character plus 1. For example, if the VIN code to be input is LSVHJ133422218720, if the input control device determines that the character has been typed is LSVH; wherein, LSVH is the typed character, and the number of the typed character is 4, then the number of digits of the current keyed position is 4+1, that is, the 5 th digit.
It is noted that, as is known from the encoding rule of the vehicle identification code, the vehicle identification code is composed of numbers 0 to 9 and capital letters other than I, O or Q, and therefore, the typed characters of the vehicle identification code do not include characters such as I, O, Q or english lowercase letters.
302. And if the number of digits of the current keyed-in position is smaller than the rated number of digits of the vehicle identification code, determining a character set to be selected corresponding to the current keyed-in position according to the coding rule corresponding to the current keyed-in position and the keyed-in characters.
And if the number of the current key-in position is less than the rated number of the vehicle identification code, the input control device determines a character set to be selected corresponding to the current key-in position according to the coding rule corresponding to the current key-in position and the key-in characters.
And if the number of currently used VIN codes is 17, determining a character set to be selected corresponding to the currently keyed-in position according to a coding rule corresponding to the currently keyed-in position and the keyed-in characters as long as the number of currently keyed-in positions of the vehicle identification codes is less than 17.
And the character set to be selected corresponding to the current key-in position is a set of possible characters of the current key-in position. For example, if the current keyed position is the 1 st position of the vehicle identification code and the input character is null, then according to the encoding rule of the vehicle identification code: the 1 st position of the vehicle identification code is used to indicate the area of the vehicle manufacturer, specifically, A-H for Africa, J-R (excluding O and Q) for Asia, S-Z for Europe, 6-7 for Atlanta, 1-5 for North America, and 8, 9, and 0 for south America. Therefore, the character set to be selected of the current bonding position can be determined to be { A-H, J-N, P, R-Z, 0-9 }.
It should be noted that the current number of digits of the vehicle identification code is different, the current meaning of the vehicle identification code is different, and the corresponding encoding rules are also different. Further, the entered character of the vehicle identification code may affect the set of characters to be selected currently entered into the field. For example, if the number of bits of the current input bit is 2, the input character is L, and the first bit L represents china according to the encoding rule of the VIN code; and according to the 2 nd bit encoding rule, taking the identification code of the China automobile manufacturer as a candidate character set of the current input bit.
303. And adjusting the input keyboard according to the character set to be selected corresponding to the current key-in position.
And the input control device adjusts the input keyboard according to the character set to be selected corresponding to the current input position.
It should be noted that, in order to facilitate the vehicle maintenance person or the vehicle owner to input the VIN code, the input keyboard may be adjusted according to the candidate character set corresponding to the current key-in position of the vehicle identification code. The embodiment of the present invention is not limited to the specific implementation of adjusting the input keyboard.
According to the embodiment of the invention, the character set to be selected of the current keyed position can be determined according to the keyed characters of the vehicle identification code and the current input position, and the input keyboard is adjusted according to the character set to be selected of the current keyed position; therefore, when the VIN code is input by the automobile maintenance personnel or the automobile owner, the VIN code is input in an instructive manner, characters which cannot be contained in the VIN code are avoided, and the error probability of the VIN code input can be reduced.
Referring to fig. 4, fig. 4 is a schematic flow chart of another input control method according to an embodiment of the present invention, and as shown in fig. 4, the input control method includes steps 401 to 407, where:
401. and determining the current key-in position and the key-in character according to the vehicle identification code key-in instruction.
The input control device determines the current key-in position and the key-in character according to the vehicle identification code key-in instruction.
The vehicle identification code typing instruction comprises a starting input instruction for the vehicle identification code, a waking instruction for a vehicle identification code input interface or a typing instruction for a previous typing position of a current typing position of the vehicle identification code.
The current key position of the vehicle identification code is the current key position to be entered on the input keyboard, and the entered character is the character already entered on the input keyboard of the vehicle identification code.
It can be understood that, if the number of digits of the currently-keyed position is 1 and the keyed character is empty, the encoding rule corresponding to the currently-keyed position is the encoding rule of the region to which the vehicle manufacturer belongs, and step 402 is executed.
402. And determining a character set to be selected corresponding to the current key-in position according to the coding rule of the area to which the vehicle manufacturer belongs and the key-in characters which are empty.
And the input control device determines a character set to be selected corresponding to the current key-in position according to the coding rule of the area to which the vehicle manufacturer belongs and the key-in characters which are empty.
It should be noted that in the encoding rule of the vehicle identification code, there is a slight difference between different countries or automobile manufacturers in interpreting WMI in the VIN code. As shown in step 301 of the embodiment corresponding to fig. 3, the 1 st digit of the vehicle identification code is used to indicate the area of the vehicle manufacturer, but some automobile manufacturers need to combine the 1 st country code of the VIN code with the 2 nd manufacturer code to be able to distinguish between the two. Similarly, some manufacturers use the first 3-bit combination code of the VIN code to represent a particular brand, as shown in Table 3, and use a combination of 1-3 bit character codes of the VIN code to represent different automobile brands.
TABLE 3
It should be noted that, if the number of digits of the currently entered position is 1 and the entered character is null, it may be determined that the set of characters to be selected of the currently entered position is: { A-H, J-R, S-Z, 0-9 }.
It can be understood that, if the number of the currently keyed position is 9 and the coding rule corresponding to the currently keyed position is the verification rule of the vehicle identification code, step 403 is executed.
403. And determining a character set to be selected corresponding to the current key-in position according to the verification rule of the vehicle identification code and the key-in character.
And the input control device determines a character set to be selected corresponding to the current key-in position according to the verification rule of the vehicle identification code and the key-in characters.
It should be noted that the 9 th bit of the vehicle identification code is a check bit of the vehicle identification code, and is used for preventing an input error of the vehicle identification code. Specifically, each character {0-9, A-H, J-N, P, R-Z } in the VIN code corresponds to a number; setting a weighted value for 1-17 bits in the VIN code; multiplying the number corresponding to the character by the weighted value of the character from the first bit of the VIN code, and calculating the sum of products of 1-8 bits and 10-17 bits; and dividing the sum of the products by 11 to obtain the remainder, namely the value of the check bit. If the remainder is 10, the parity bit has a value of X.
It can be seen that the specific value of the check bit can be calculated when the 10-17 bits of the VIN code are known. However, according to the encoding rule of the check digit of the vehicle identification code, the 9 th-bit candidate character set of the vehicle identification code is {0-9, X }.
If the number of bits of the current key-in position is 10 and the coding rule corresponding to the current key-in position is the coding rule of the year of production of the vehicle, step 404 is executed.
404. And determining a character set to be selected corresponding to the current input position according to the coding rule of the vehicle production year and the typed characters.
The input control device determines a character set to be selected corresponding to the current input position according to the coding rule of the production year of the vehicle and the input characters.
Wherein, the 10 th bit of the vehicle identification code is the model year of the vehicle, namely the model year. The year corresponding to the 10 th character code of the vehicle identification code is shown in table 4, and different character codes represent different years.
TABLE 4
| Character code | Year of year | Character code | Year of year | Character code | Year of year | Character code | Year of year |
| B | 1981 | K | 1989 | V | 1997 | 5 | 2005 |
| C | 1982 | L | 1990 | W | 1998 | 6 | 2006 |
| D | 1983 | M | 1991 | X | 1999 | 7 | 2007 |
| E | 1984 | N | 1992 | Y | 2000 | 8 | 2008 |
| F | 1985 | P | 1993 | 1 | 2001 | 9 | 2009 |
| G | 1986 | R | 1994 | 2 | 2002 | ||
| H | 1987 | S | 1995 | 3 | 2003 | ||
| J | 1988 | T | 1996 | 4 | 2004 |
It should be further noted that the model year specified by the manufacturer is not necessarily the actual year of production of the automobile, but generally differs from the actual year of production by no more than 1 year. Table 4 shows a correspondence table between each year of 1981-2009 in the vehicle identification code and the character code. In the embodiment of the invention, the character set to be selected in the current keyed position can be determined according to the scrappage of the vehicle. For example, if the Chinese scrap age is 10 years and the current time is 2009, the characters have been entered as follows: LSVHJ1330, the number of bits currently bonded is 9; then the currently entered character set to be selected is determined as X-Y, 1-9, based on table 4 and the age of the vehicle.
If the number of currently-keyed positions is 11 and the coding rule corresponding to the currently-keyed position is the coding rule of the vehicle assembly plant, step 405 is executed.
405. And determining a character set to be selected corresponding to the current key-in position according to the automobile manufacturer determined by the 1-3 key-in characters of the vehicle identification code, the automobile type determined by the 4-8 key-in characters of the vehicle identification code and the coding rule of the vehicle assembly factory.
The input control device determines a character set to be selected corresponding to the current key-in position according to the automobile manufacturing plant determined by the 1-3 key-in characters of the vehicle identification code, the automobile type determined by the 4-8 key-in characters of the vehicle identification code and the coding rule of the vehicle assembly plant.
Wherein, the 11 th bit of the vehicle identification code is a character representing a vehicle assembly factory. If the number of currently-keyed bits is 11, it is assumed that the first 10 bits of the vehicle identification code are known. According to the encoding rule of the vehicle identification code, the manufacturer of the automobile can be determined according to 1-3 bits of the VIN code; and the vehicle type of the vehicle can be determined according to 4-8 bits of the VIN code. Therefore, the character set corresponding to the vehicle model assembly factory under the corresponding vehicle model can be determined according to the vehicle manufacturing factory and the vehicle model.
If the number of currently-keyed bits is 12 to 17 and the encoding rule corresponding to the currently-keyed bit is the encoding rule of the vehicle delivery sequence number, step 406 is executed.
406. And determining a character set to be selected corresponding to the current keyed-in position according to the coding rule of the vehicle factory sequence number and the keyed-in characters.
And the input control device determines a character set to be selected corresponding to the current keying-in position according to the coding rule of the vehicle delivery sequence number and the keyed-in characters.
Wherein, 12-17 bits of the vehicle identification code are the delivery sequence number of the vehicle, and are set by an automobile manufacturer.
407. And adjusting the input keyboard according to the character set to be selected corresponding to the current key-in position.
And the input control device adjusts the input keyboard according to the character set to be selected corresponding to the current input position.
It should be noted that the input keyboard in the embodiment of the present invention may be adjusted on a system input keyboard on the input control device, or may be an input keyboard specially used for VIN code input determined according to a to-be-selected character set corresponding to a current key position.
As a possible implementation manner, a specific implementation manner of adjusting the input keyboard according to the to-be-selected character set corresponding to the current typing position is as follows: acquiring a character set contained in an input keyboard; deleting characters except the character set to be selected in the character set; and displaying characters in the character set to be selected on the input keyboard.
For example, if the number of currently-entered bits of the vehicle identification code is 1, the entered character is null. According to the coding rule of the vehicle identification code, the 1 st character set to be selected of the vehicle identification code is { A-H, J-N, P, R-Z, 0-9 }. The currently entered input keyboard may be adjusted in the manner of deleting characters as described above, and the adjusted input keyboard is as shown in fig. 5.
For example, if the number of currently-entered bits of the vehicle identification code is 9, the entered characters of the vehicle identification code are: "LSVHJ 133 _", where the underlining "_" indicates the current bonding position. According to the encoding rule of the vehicle identification code, if the 9 th-bit candidate character set of the vehicle identification code is {0-9, X }, the input keyboard of the current key-in position can be adjusted in the above character deleting manner, and the adjusted input keyboard is as shown in fig. 6.
In the above embodiment, only the characters in the currently entered optional character set are displayed on the basis of the system input keyboard.
Optionally, the specific implementation of adjusting the input keyboard according to the to-be-selected character set corresponding to the current typing position further includes: acquiring a character set contained in an input keyboard; and setting characters except the character set to be selected in the character set contained in the input keyboard to be in a non-enabled state, and setting the characters in the character set to be selected to be in an enabled state. That is to say: the method can set characters in a character set to be selected, in which a vehicle identification code is currently keyed in, to be in an enabled state on a general system input keyboard, and sets characters, except the character set to be selected, contained in the input keyboard to be in a non-enabled state. Therefore, when a vehicle maintenance person or a vehicle owner inputs the VIN code, the vehicle maintenance person or the vehicle owner cannot select characters except the character set to be selected, and the probability of error input of the vehicle identification code is reduced.
According to the embodiment of the invention, the character set to be selected of the current keyed position can be determined according to the current keyed position of the vehicle identification code and the keyed characters; adjusting an input keyboard according to the currently-keyed character set to be selected; therefore, when a vehicle maintenance person or a vehicle owner inputs the VIN code, the characters displayed on the input keyboard can be adjusted according to the current key-in position and the key-in characters, so that the characters which cannot appear in the VIN code are prevented from being input, and the probability of VIN input errors is reduced.
