Referring to fig. 3 and 4, due to the error, mechanical error, installation error and the like of the monostable knob type electronic gear shifter 200, the angle of each position of each knob type monostable electronic gear shifter has unknown deviation, and in order to eliminate the unknown deviation, each knob type monostable electronic gear shifter needs to be calibrated to achieve accurate gear shifting. The calibration method of the knob type electronic gear shifter 200 is that an operator manually and sequentially places the knob type monostable electronic gear shifter on a plurality of positions L2, L1, 0, R1 and R2 (the P gear is detected by using a button and does not need to be calibrated), and then the angle of each position is calibrated. The monostable knob type electronic shifter 200 generally has only one stable state, and when the knob is turned a certain angle and hands are released, the knob automatically returns to the original position. The monostable knob type electronic shifter 200 may be of different kinds depending on the setting of the P-range, for example the P-range is provided integrally with the shifter. When the P-gear is arranged in the middle of the knob of the monostable knob type electronic shifter 200, the P-gear is integrated with the integral monostable knob type electronic shifter 200, and the P-gear is usually arranged in a key mode, so that the P-gear does not need to be calibrated. The knob type monostable electronic shifter usually reads an angle value of a current position from an internal hall chip as a rotation angle of the current position. The principle of the gear shifter for reading the angle is that the knob drives the circular magnet to rotate, the rotation of the circular magnet is sensed by the non-contact rotary Hall IC beside the circular magnet, and the rotation of the circular magnet is acquired by the MCU to obtain the angle value.
Referring to FIG. 1, the components of the electronic device 100 include, but are not limited to, a memory 110 and a processor 120. The processor 120 is coupled to the memory 110 via a bus 130 and the database 160 is used to store data.
The electronic device 100 also includes an access device 140, the access device 140 enabling the electronic device 100 to communicate via one or more networks 150. Examples of such networks include the Public Switched Telephone Network (PSTN), a Local Area Network (LAN), a Wide Area Network (WAN), a Personal Area Network (PAN), or a combination of communication networks such as the internet. Access device 140 may include one or more of any type of network interface, e.g., a Network Interface Card (NIC), wired or wireless, such as an IEEE802.11 Wireless Local Area Network (WLAN) wireless interface, a worldwide interoperability for microwave access (Wi-MAX) interface, an ethernet interface, a Universal Serial Bus (USB) interface, a cellular network interface, a bluetooth interface, a Near Field Communication (NFC) interface, and so forth.
In some embodiments of the invention, the above-mentioned components of the electronic device 100 and other components not shown in fig. 1 may be connected to each other, for example by a bus. It should be understood that the block diagram of the electronic device shown in fig. 1 is for exemplary purposes only and is not intended to limit the scope of the present invention. Those skilled in the art may add or replace other components as desired. The electronic device 100 may be any type of electronic device 100, such as a computer, a smart phone, a smart tablet, and the like.
Wherein the processor 120 may perform the steps of the device status detection method shown in fig. 2. Fig. 2 shows a flowchart of a calibration method of a knob type electronic shifter according to an embodiment of the present invention, and referring to fig. 2, includes steps S100 to S300.
Step S100: and controlling the display to sequentially send out display prompts corresponding to each gear to be calibrated one by one.
Step S200: the determination signals corresponding to the display prompts one to one are respectively acquired from the P-gear of the knob type electronic shifter 200, and the corresponding rotation angle is acquired according to each determination signal.
Step S300: and setting each rotation angle as a calibration angle value of each corresponding gear to obtain a plurality of calibration angle value sets corresponding to the gears to be calibrated, and transmitting the calibration angle value sets corresponding to the gears to be calibrated to the knob type electronic gear shifter 200 for storage.
Referring to fig. 5, it can be understood that the controlling the display device sequentially sends out the display prompts corresponding to each gear to be calibrated one by one, including: before each gear to be calibrated is calibrated, controlling a display to respectively send out a first prompt corresponding to each gear to be calibrated; and after the calibration value of each gear to be calibrated is obtained, controlling the display to respectively send out a second prompt corresponding to each gear to be calibrated. Specifically, the marks of the P gear, the 0 gear, the L1 gear, the L2 gear, the R1 gear and the R2 gear are displayed on the display; when any gear of the gears 0, L1, L2, R1 and R2 needs to be calibrated, the corresponding mark of the gear is lightened in a first color; when any one of the gears of the gear 0, the gear L1, the gear L2, the gear R1 and the gear R2 is calibrated, the corresponding mark of the gear is lightened in a second color; and when a determination signal transmitted from the P gear is received, the corresponding mark of the P gear is lightened, and the mark is extinguished after the preset time. The first color is red and the second color is green.
Referring to fig. 6, it can be understood that the method further includes: and respectively rotating the range formed by the preset distance clockwise and anticlockwise by taking the rotating angle corresponding to each calibration value as a center to determine the range as the triggering range of the gear corresponding to the calibration value. Because each gear corresponds to a fixed angle, if the gear is just rotated to a corresponding angle, the difficulty in operation can be brought in practical application, and through the arrangement, in practical application, when the knob type electronic gear shifter is rotated to be close to the corresponding gear, the automobile can be switched to the corresponding gear to run, so that the practicability of the knob type electronic gear shifter is improved. The solid line identifies the gear hall angle calibration value, and the dotted line identifies the logic threshold value (which can be modified by software) calculated from the calibration value; it is necessary to cross to the left from the resident gear 0 to the dashed arrow to identify it as L1; from L1, it crosses right to the solid arrow to identify gear 0 as resident; the gear shift from L1 to the left needs to be crossed to the dotted arrow to be identified as L2; from L2, it crosses right to the solid arrow to be identified as L1; the right-hand processing strategy is the same as the left-hand one.
It is understood that data is exchanged with the knob type electronic shifter 200 through the CAN bus. Further comprising: the rotation angle of the knob type electronic shifter 200 in the initial state is obtained and used as an original gear calibration value of the knob type electronic shifter 200. The original state is a 0 ° value (zero point), and the zero point may be a steady-state point, that is, the zero point is used as a base point to mark other gears. For example, the angle of zero is 0 °, the angle of R1 may be 30 °, and the angle of L1 may be-30 ° or 270 °.
It CAN be understood that a CAN bus calibration command is sent in a simulation mode, the position needing to be calibrated at present is indicated, an operator rotates a gear shifting knob to a corresponding position according to the calibration position indicated by calibration, the current Hall angle value CAN be read through the notification of a P gear key, the CAN command for reading the Hall angle value at the current position is sent to a gear shifter immediately, therefore, Hall angles of L2, L1, 0, R1 and R2 are read out in sequence to serve as Hall angle calibration values, and finally the CAN command is sent to send the calibration angle values to an EEPROM inside the gear shifter to be stored.
It will be appreciated that in some specific implementations, the monostable knob type electronic shifter calibration method includes the steps of:
