An embodiment of the invention provides a gear self-learning method, and referring to fig. 2, fig. 2 is a schematic flow diagram of a first embodiment of the gear self-learning method.
In this embodiment, the gear self-learning method includes the following steps:
step S10: and receiving an input self-learning instruction.
In this embodiment, the execution main body of this embodiment may be a gear self-learning device, the gear self-learning device has functions of data processing, data communication, program operation and the like, and the gear self-learning device may be an electronic gear shift actuator. Of course, other devices with similar functions may be used, and the present embodiment is not limited thereto. For convenience of explanation, the present embodiment will be described taking an electronic shifter actuator as an example.
It should be noted that, in the current gear self-learning, separate learning is performed on all gears, an approximate central duty ratio value of each gear is obtained and stored according to a method of averaging for multiple gear shifts (generally more than 4 times), and then a duty ratio value range corresponding to each gear is determined according to the central duty ratio value, so that the gear self-learning efficiency is low. Moreover, for a fixed whole vehicle, under the condition of known vehicle parameters, the operations are redundant and have poor timeliness, the motor is controlled to rotate forward and backward for a plurality of times too frequently in a short time, the risk of excessive heating and even breakdown of the motor and a driving circuit formed by the motor and semiconductor components can be caused, and the service life of vehicle components is reduced by the current gear self-learning mode.
Aiming at the technical problems, the positions of the preset gears are learned by self, then the positions of other gears are learned according to the learned positions of the gears and the angle relation among the gears, the positions of the gears are not required to be obtained in a self-learning mode of multiple gear shifting, the gear self-learning efficiency is improved, and meanwhile the safety of vehicle parts is guaranteed.
In specific implementation, in order to ensure the accuracy of self-learning, in this embodiment, before gear self-learning is performed, a gear needs to be adjusted to a preset gear, and then subsequent gear self-learning is performed, and before the preset gear is switched, a self-learning instruction needs to be received.
Step S20: and switching the gear to a preset gear according to the gear shifting operation instruction.
In a specific implementation, after the self-learning instruction is received, the gear is switched to the preset gear according to the received self-learning instruction. The preset gear in this embodiment may be set to a neutral gear, that is, N gear, and of course, other gears may be selected as the preset gear according to the actual condition.
Step S30: and powering off the whole vehicle so as to enable the gears to fall back from the positions where the preset gears are located.
In the concrete implementation, after the gear is switched to the preset gear, the whole vehicle is powered off in the embodiment, after the whole vehicle is powered off, the gear falls back from the position where the preset gear is located, and the gear falls back automatically after the power is off of the whole vehicle without additional control operation.
Step S40: and after the whole vehicle is electrified again, acquiring the target position of the gear after gear return is completed.
In specific implementation, the gear can fall back to other positions after the power failure of the whole vehicle, and after the falling process of the whole gear is completed, the vehicle can be powered on again in the embodiment, and then the position of the current gear is obtained, that is, the target position where the gear is located after the gear falls back is completed.
It should be noted that the self-learning position of the gear, that is, the target position in this embodiment, may be obtained by powering on again after power-off and falling.
Step S50: and determining the positions of other gears according to the target position so as to complete gear self-learning.
In this embodiment, the target position is a self-learning position of the gear, and since the gear falling is started from the preset gear in this embodiment, the target position is also a self-learning position of the preset gear, for example, assuming that the preset gear is N gear, that is, the target position is a self-learning position of N gear, after the target position is determined, based on a relationship between each gear, the self-learning positions of other gears may be obtained based on the target position in this embodiment, thereby completing the self-learning of all gears of the entire vehicle. For example, after the self-learning position of the N gear is obtained, the positions of other gears, such as P gear, N gear, D gear and R gear, can be obtained according to the self-learning position of the N gear.
The embodiment is realized by receiving an input gear shifting operation instruction; switching the gear to a preset gear according to the gear shifting operation instruction; powering off the whole vehicle to enable the gear to fall back from the position where the preset gear is located; acquiring a target position of the gear after gear return is completed; the positions of other gears are determined according to the target position to complete gear self-learning, the positions of the preset gears are obtained through learning in a power-off falling mode, then the positions of the other gears are obtained through learning according to the positions of the preset gears, multiple gear shifting and frequent positive and negative rotation of a motor are avoided, gear self-learning efficiency is improved, meanwhile, abrasion of vehicle parts is reduced, and the service life of the vehicle parts is prolonged.
Referring to fig. 3, fig. 3 is a schematic flow chart of a gear self-learning method according to a second embodiment of the present invention.
Based on the first embodiment, in the gear self-learning method according to this embodiment, the step S30 specifically includes:
step S301: and powering off the whole vehicle so as to enable the gears to fall back from the positions where the neutral gears are located for the first time.
It should be noted that, in this embodiment, power-off gear drop-back and power-on again after gear drop-back are performed twice, that is, the first gear drop-back and the second gear drop-back in this embodiment.
In specific implementation, after the gear is switched to the preset gear, the whole vehicle is powered off in the embodiment, then the gear starts to fall back from the position where the preset gear is located for the first time, after the first gear fall back is completed, the whole vehicle is powered on again in the embodiment, then the whole vehicle is powered off again, then the preset gear starts to fall back for the second time, and finally the whole vehicle is powered on again, so that the self-learning process of the preset gear is completed.
Step S302: and after the whole vehicle is electrified again, acquiring the current position of the gear after the gear falls back for the first time.
In specific implementation, the preset gear is set as a neutral gear in this embodiment, before the first fall-back, the gear is switched to the position where the neutral gear is located, then the whole vehicle is powered off, after the first fall-back of the gear is completed, the whole vehicle is powered on again, and at this time, the current position where the gear is located is obtained.
Step S303: when the current position is not located at the preset position, the whole vehicle is powered off for the second time, so that the gear is located at the current position and is subjected to secondary gear falling.
It should be noted that after the gear falls back, the gear may fall back to other positions from the initial position where the neutral gear is located, and for different positions where the gear falls back, in this embodiment, the judgment is performed through a preset position, and then the self-learning position of the neutral gear is finally obtained based on different judgment results.
In fig. 4, the preset position in this embodiment is a D-shift position, that is, positions 3 and 4 shown in fig. 4 are positions, and the current position is not in the D-shift position, and the shift positions are positions 1 and 2 at this time. In addition, in the shift 1 position, P or R range information may be received but N range information may not be received, in the shift 2 or 3 position, P, R and N range information may not be received but D range information may be received, and in the shift 4 position, P, R, N and D range information may be received.
In specific implementation, in this embodiment, the current position of the neutral gear after the first gear falling is completed is compared with a preset position, and if the current position is not located at the preset position, in this case, the power of the entire vehicle is further turned off in this embodiment, and then the secondary gear falling is directly started, at this time, the neutral gear will continue to fall back to other positions from the current position located after the first gear falling, and it needs to be emphasized that the position where the neutral gear is located after the secondary gear falling is completed is the target position in this embodiment, which is also the neutral self-learning position.
Further, if the shift position at this time is in the D-shift position, in this case, in this embodiment, the shift position is controlled to rotate in the reverse direction according to the calibration angle, and then the shift position is rotated to the new current position, and then the power of the entire vehicle is cut off for the second time, so that the shift position starts to fall back for the second time from the new current position. Likewise, the position of the gear after the completion of the secondary fall-back is the target position described in the present embodiment, which is also the neutral self-learning position. In this embodiment, the calibration angle may be set according to the mechanical structure of the gear control of different vehicles, which is not limited in this embodiment.
Further, in this embodiment, the step S50 specifically includes:
step S501: and acquiring a gear angle difference between the preset gear and other gears.
It should be noted that each gear has a corresponding gear angle difference, which is determined by the mechanical structure of the gear control of the vehicle itself and can be directly obtained. It should be noted that in this embodiment, the gears fall back from the preset gears, and the target position where the gears fall back is the self-learning position of the preset gears, so that when determining the positions of other gears, the gear angle difference between the preset gears and other gears needs to be obtained. For example, assuming that the preset gear is the N gear, the gear angle differences between the N gear and the P gear, the D gear, and the R gear are obtained respectively.
Step S502: and determining the positions of other gears according to the gear angle difference and the target position.
In this embodiment, after determining the gear angle difference between each gear, the target position is added or subtracted with the gear angle difference to obtain the positions of other gears, thereby completing self-learning of each gear.
In the embodiment, the power of the whole vehicle is cut off, so that the gear falls back from the position of the neutral gear for the first time; acquiring the current position of the gear after the gear falls back for the first time; when the current position is not at the preset position, carrying out secondary power-off on the whole vehicle so as to enable the gear to carry out secondary gear falling from the current position; when the current position is at a preset position, controlling the gear to reversely rotate according to a calibration angle, and acquiring a new current position of the gear; it is right the whole car carries out the secondary outage, so that keep off the position and follow new current position carries out the secondary and keeps off the position and fall back, through twice outage fall back and take corresponding mode to the fender position after the first fall back to adjust to the fender position after the first fall back to different positions after the first fall back, can more accurately obtain predetermine the self-learning position of keeping off the position, thereby improved the accuracy that keeps off the position and learn by oneself.
Referring to fig. 5, fig. 5 is a schematic flow chart of a third embodiment of the gear self-learning method according to the present invention.
Based on the first or second embodiment, a third embodiment of the gear self-learning method of the present invention is provided.
Taking the first embodiment as an example, in this embodiment, the step S40 is followed by:
step S60: and detecting whether the current gear is a parking gear.
In addition, each part of the vehicle is worn away with long-term use, and in this embodiment, the gear shifter is self-learned twice when the user uses the vehicle daily. When the second self-learning is carried out, the current gear needs to be guaranteed to be the parking gear.
Step S70: and when the current gear is a parking gear, performing secondary gear self-learning on the gear and other gears, and outputting a corresponding gear self-learning prompt.
In a specific implementation, when it is detected that the current gear is the parking gear, it is described that a condition for performing self-learning is satisfied at this time, in this case, the gear of the vehicle is controlled to perform secondary gear self-learning in this embodiment, and a gear self-learning prompt is output at the same time to inform a user that the vehicle is performing gear self-learning. The process of the gear self-learning in this embodiment is similar to the process in the above embodiment, and is not described here again.
Further, in this embodiment, it is necessary to detect whether a secondary self-learning command is received or whether the current driving mileage of the entire vehicle is acquired, in addition to ensuring that the current gear is the parking gear, and after the current gear is the parking gear, gear self-learning can be started when the two conditions are met. Specifically, when the current gear is the parking gear, if a secondary self-learning command is received, the vehicle is controlled to start gear self-learning. Or when the current gear is the parking gear, if the current driving mileage reaches a preset mileage, controlling the vehicle to start gear self-learning, where the preset mileage may be set according to an actual gear self-learning requirement, which is not limited in this embodiment.
Whether this embodiment is the parking fender position through detecting current fender position to when the current mileage of receiving self-learning order or whole car reaches preset mileage, it is right fender position and other fender positions carry out the secondary and keep off the position self-learning to export corresponding fender position self-learning suggestion, avoid leading to each part of vehicle to produce wearing and tearing along with the long-time use of vehicle, cause the position of keeping off the position inaccurate, through at the follow-up in-process of using the car of user, can also self-learn the fender position of the executor of shifting of vehicle, promoted user experience.
