[0076] Among them, the first gear shift self-learning conditions include: the engine speed of the ship engine is zero, the ship speed of the ship engine is zero, and the battery voltage of the ship engine is within a preset range.

[0077] In a specific embodiment, the specific implementation of judging whether the ship engine shift mechanism has performed the first shift self-learning includes:

[0079] Specifically, the number of gear shift self-learning times and the initial value of the number of gear shift self-learning times corresponding to the first gear shift self-learning not being performed are stored in the memory, wherein the initial value is the preset number of times.

[0080] After each gear shift self-learning is completed, the gear shift self-learning times are increased by 1 and accumulated.

[0081] In a specific embodiment, the gear switching signal includes: a first signal for indicating that the neutral gear is switched to the forward gear, a second signal for indicating that the forward gear is switched to the neutral gear, a third signal for indicating that the neutral gear is switched to the reverse gear, and a fourth signal for indicating that the reverse gear is switched to the neutral gear. The first signal corresponds to a first preset value, the second signal corresponds to a second preset value, the third signal corresponds to a third preset value, and the fourth signal corresponds to a fourth preset value.

[0082] The limit voltage values ​​include: an upper limit value of a forward gear and a lower limit value of a forward gear, an upper limit value of a neutral gear and a lower limit value of a neutral gear, and an upper limit value of a reverse gear and a lower limit value of a reverse gear.

[0084] In the process of driving the duty cycle to the first preset value, the voltage value corresponding to when the signal change rate is equal to the first preset change rate is determined as the lower limit value of the forward gear.

[0085] In the process of driving the duty cycle to the first preset value, when the signal change rate is equal to the second preset change rate, the first average value of the voltage value of the gear signal is calculated, and the first average value is determined as the upper limit value of the forward gear, wherein the first preset change rate is greater than the second preset change rate.

[0086] In the process of driving the duty cycle to the second preset value, when the signal change rate is equal to the first preset change rate, the corresponding voltage value is determined as the upper limit value of the neutral gear.

[0090] In a specific embodiment, the specific implementation of driving the duty cycle to a preset value corresponding to the current gear switching signal includes:

[0091] When it is determined that the current gear switching signal is the first signal, driving is stopped when the voltage value of the gear signal increases to a first preset voltage value; when it is determined that the current gear switching signal is the second signal, driving is stopped when the voltage value of the gear signal decreases to a second preset voltage value; when it is determined that the current gear switching signal is the third signal, driving is stopped when the voltage value of the gear signal decreases to a third preset voltage value; when it is determined that the current gear switching signal is the fourth signal, driving is stopped when the voltage value of the gear signal increases to a fourth preset voltage value.

[0092] In a specific embodiment, the first preset voltage value is obtained by a first calculation formula, the second preset voltage value is obtained by a second calculation formula, the third preset value is obtained by a third calculation formula, and the fourth preset value is obtained by a fourth calculation formula.

[0093] The first calculation formula is shown in Formula 1:

[0094] ;

[0095] in, represents a first preset voltage value, The lower limit of the forward gear, The upper limit of the forward gear, Represents a constant.

[0096] The second calculation formula is shown in Formula 2:

[0102] The fourth calculation formula is shown in Formula 4:

[0103] ;

[0104] in, Indicates a fourth preset voltage value.

[0105] Below, the first preset value is 100%, the second preset value is -50%, the third preset value is -100%, and the fourth preset value is 50%. is 20%, The specific implementation of this application is illustrated by taking 80% as an example.

[0106] The gear position signal is collected during the 100% duty cycle driving process, and the collected gear position signal is differentiated to obtain the signal change rate of the gear position signal. When the signal change rate slows down significantly (the corresponding signal change rate is equal to the first preset change rate), the corresponding voltage value is the lower limit of the forward gear. When the signal change rate no longer changes (the corresponding signal change rate is equal to the second preset change rate), the average value of the voltage value of the collected gear position signal is calculated, and the first average value obtained is determined as the upper limit of the forward gear.

[0107] The gear signal is collected during the process of duty cycle driving to -50%, and the collected gear signal is differentiated to obtain the signal change rate of the gear signal. When the signal change rate slows down significantly (the corresponding signal change rate is equal to the first preset change rate), the corresponding voltage value is the upper limit value of the neutral gear.

[0108] The gear position signal is collected during the process of driving the duty cycle to -100%, and the collected gear position signal is differentiated to obtain the signal change rate of the gear position signal. When the signal change rate slows down significantly (the corresponding signal change rate is equal to the first preset change rate), the corresponding voltage value is the upper limit of the reverse gear. When the signal change rate no longer changes (the corresponding signal change rate is equal to the second preset change rate), the voltage value of the collected gear position signal is averaged, and the obtained second average value is determined as the lower limit of the reverse gear.

[0109] The gear signal is collected during the process of duty cycle driving to 50%, and the collected gear signal is differentiated to obtain the signal change rate of the gear signal. When the signal change rate slows down significantly (the corresponding signal change rate is equal to the first preset change rate), the corresponding voltage value is the lower limit value of the neutral gear.

[0110] Specifically, the gear position corresponds to an interval and is a fixed value. In order to prevent the gear from not being shifted in place, a sufficiently large and long driving force is required to ensure a successful gear shift. In addition, since the gear shift mechanism has inertia, if the drive is too large, it is easy to hit the mechanical dead zone position of the gear shift mechanism, affecting the service life of the gear shift mechanism, because this application adopts a 2:8 drive method for driving processing.

[0111] When the current gear switching signal is determined to be the first signal, the duty cycle is given a positive value. As the driving time becomes longer, the gear actuator begins to move, and the voltage value of the gear signal gradually increases. When the voltage value increases to When the current gear switching signal is determined to be the second signal, the duty cycle is given a negative value. As the driving time becomes longer, the gear actuator begins to move, and the voltage value of the gear signal gradually decreases. When the voltage value decreases to When the current gear switching signal is determined to be the third signal, the duty cycle is given a negative value. As the driving time becomes longer, the gear actuator begins to move, and the voltage value of the gear signal gradually decreases. When the voltage value decreases to When the current gear switching signal is determined to be the fourth signal, the duty cycle is given a positive value. As the driving time becomes longer, the gear actuator begins to move, and the voltage value of the gear signal gradually increases. When the voltage value increases to The drive stops.

[0112] In a specific embodiment, after all gear switching signals corresponding to the current gear shift self-learning are executed, the number of tilting operations is reset to zero.

[0113] Specifically, as the gears are used, wear and tear will occur, causing the gears to change. Therefore, at the beginning of each driving cycle, gear shift self-learning is performed only if the gear shift self-learning conditions are met, and the number of gear shift operations is reset to zero after the gear shift self-learning is completed so that the number of gear shift operations can be counted again.

[0114] This application considers the cumulative effect of gear signal wear, self-learns the intervals of different gears, and uses the 80 / 20 principle to determine whether the gear of the ship engine is driven in place, avoiding the situation where the gear is not driven in place or overdriven. And based on the number of tilting operations as the trigger condition for gear shift self-learning, it avoids the frequent triggering of gear shift self-learning, reduces the wear of the ship engine gear shift mechanism, and increases the service life of the ship engine gear shift mechanism.

[0115] The embodiment of the present application also provides a gear position voltage determination device for a ship engine shift mechanism.

[0119] The iteration module 203 is used to obtain the next gear switching signal and execute the voltage value determination process based on the next gear switching signal until all gear switching signals corresponding to the current gear shift self-learning are executed.

[0120] Among them, the gear shift self-learning conditions must be continuously met during the entire process of a gear shift self-learning.
