[0002] The ship's engine uses a shifting mechanism to move the ship forward and backward. This mechanism includes three gears: forward, reverse, and neutral. The forward, reverse, and neutral gears are determined by the magnitude of the acquired voltage signal, and the voltage value for each gear is not a fixed value but a range. For example, reverse corresponds to 500mV-1500mV, neutral corresponds to 2000mV-3000mV, and forward corresponds to 3500-4500mV.

[0003] As the shifting mechanism is used and wears out, the voltage range of forward gear, reverse gear and neutral gear may shift, causing error messages such as insufficient drive or overdrive when shifting gears, resulting in shifting failure. Technical issues

[0065] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0066] This application provides a method for determining the gear position voltage of a ship engine shifting mechanism. This method can be applied to smart terminals, servers, and ship engine controllers. Other descriptions in this application are illustrative and not intended to limit the scope of protection of this application, and will not be described in detail thereafter. The specific implementation of this method is shown in Figure 1:

[0067] Step 101: If the ship engine meets the self-learning conditions for gear shifting, obtain the current gear switching signal.

[0068] The shift self-learning conditions include: the number of times the ship engine's lifting device performs lifting operations is greater than or equal to a preset threshold, the ship engine speed is zero, the ship speed is zero, and the ship engine's battery voltage is within a preset range.

[0069] The control handle of the ship engine includes a lifting device operation button. Users can operate the lifting device operation button according to their actual needs to trigger the lifting signal. The controller increments the lifting operation count by 1 each time it receives a lifting signal.

[0070] Step 102: Based on the current gear shift signal, perform the following voltage value determination process: drive the duty cycle to a preset value corresponding to the current gear shift signal, and acquire the gear signal during the process of driving to the preset value; perform differential calculation on the gear signal to obtain the signal change rate of the gear signal, and determine the limit voltage value corresponding to the current gear shift signal based on the signal change rate; acquire the previous limit voltage value corresponding to the current gear shift signal during the previous gear shift self-learning process, and perform weighted summation on the limit voltage value and the previous limit voltage value to obtain the target limit voltage value.

[0071] For example, if the weight of the previous limiting voltage value is 80% and the weight of the current limiting voltage value is 20%, the target limiting voltage value, i.e., the current limiting voltage value, is obtained by weighted summation. Or, for another example, if the weight of the previous limiting voltage value is 70% and the weight of the current limiting voltage value is 30%, the target limiting voltage value is obtained by weighted summation.

[0072] Step 103: Obtain the next gear shift signal and perform a voltage value determination process based on the next gear shift signal until all gear shift signals corresponding to the current gear shift self-learning have been executed.

[0073] Throughout the entire process of a gear shift self-learning, the gear shift self-learning conditions must be continuously met.

[0074] The gear voltage determination method for the ship engine shifting mechanism provided in this application, when the ship engine meets the shifting self-learning conditions, performs the following voltage value determination process based on the current gear switching signal to obtain the voltage range of each gear of the ship engine shifting mechanism. This process is automatically triggered based on the shifting self-learning conditions, ensuring that the voltage range of the gear is effectively updated and accurate according to the actual situation. It solves the problem of shifting failure caused by insufficient or excessive drive when shifting ship engines in the prior art, improves the accuracy of recognizing user operation, and increases the shifting success rate.

[0075] Furthermore, considering the cumulative effect of gear signal wear, this application employs a weighted summation of the limit voltage value and the previous limit voltage value to obtain the target limit voltage value, further ensuring the accuracy of the voltage range. Moreover, using the number of lifting operations of the lifting device as the trigger condition for gear shift self-learning avoids the problem of frequent triggering of gear shift self-learning leading to accelerated gear wear.

[0076] In one specific embodiment, before acquiring the current gear shift signal when it is determined that the ship engine meets the gear shift self-learning conditions, it is determined whether the ship engine gear shifting mechanism has performed the first gear shift self-learning; if it is determined that the ship engine gear shifting mechanism has performed the first gear shift self-learning, the step of acquiring the current gear shift signal when it is determined that the ship engine meets the gear shift self-learning conditions is executed; if it is determined that the ship engine gear shifting mechanism has not performed the first gear shift self-learning, it is determined whether the ship engine meets the first gear shift self-learning conditions; if it is determined that the ship engine meets the first gear shift self-learning conditions, the step of acquiring the current gear shift signal is executed.

[0077] The conditions for the first gear shift self-learning include: the engine speed of the ship's engine is zero, the ship's speed is zero, and the battery voltage of the ship's engine is within the preset range.

[0078] In one specific embodiment, the specific implementation of determining whether the ship engine shifting mechanism has performed its first shift self-learning includes:

[0079] Obtain the pre-stored number of shift self-learning times; if the number of shift self-learning times is less than the preset number, determine that the ship engine shift mechanism has not performed the first shift self-learning; if the number of shift self-learning times is greater than or equal to the preset number, determine that the ship engine shift mechanism has performed the first shift self-learning.

[0080] Specifically, the number of shift self-learning times and the initial value of the number of shift self-learning times corresponding to the first shift self-learning not being performed are stored in the memory, where the initial value is the preset number.

[0081] The number of shift self-learning cycles is incremented by 1 after each shift self-learning cycle is completed, and this is accumulated.

[0082] In one specific embodiment, the gear shifting signal includes: a first signal for indicating shifting from neutral to drive, a second signal for indicating shifting from drive to neutral, a third signal for indicating shifting from neutral to reverse, and a fourth signal for indicating shifting from reverse to neutral. 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.

[0083] The limiting voltage values ​​include: the upper and lower limits of forward gear, the upper and lower limits of neutral gear, and the upper and lower limits of reverse gear.

[0084] The specific implementation of driving the duty cycle to a preset value corresponding to the current gear shift signal and acquiring the gear signal during the process of driving to the preset value; performing differential calculation on the gear signal to obtain the signal change rate of the gear signal, and determining the limit voltage value corresponding to the current gear shift signal based on the signal change rate includes:

[0085] During the process of driving the duty cycle to the first preset value, the voltage value corresponding to the signal change rate being equal to the first preset change rate is determined as the lower limit value of the forward gear.

[0086] During 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.

[0087] During the process of driving the duty cycle to the second preset value, the voltage value corresponding to the signal change rate being equal to the first preset change rate is determined as the upper limit value of the neutral position.

[0088] During the process of driving the duty cycle to the fourth preset value, the voltage value corresponding to the signal change rate being equal to the first preset change rate is determined as the lower limit of the neutral position.

[0089] During the process of driving the duty cycle to the third preset value, the voltage value corresponding to the signal change rate being equal to the first preset change rate is determined as the upper limit value of the reverse gear.

[0090] During the process of determining the duty cycle to the third preset value, when the signal change rate is equal to the second preset change rate, the second average value of the voltage value of the gear signal is calculated, and the second average value is determined as the lower limit value of the reverse gear.

[0091] In one specific embodiment, the specific implementation of driving the duty cycle to a preset value corresponding to the current gear shift signal includes:

[0092] If the current gear shift signal is determined to be the first signal, the drive stops when the voltage value of the gear signal increases to the first preset voltage value; if the current gear shift signal is determined to be the second signal, the drive stops when the voltage value of the gear signal decreases to the second preset voltage value; if the current gear shift signal is determined to be the third signal, the drive stops when the voltage value of the gear signal decreases to the third preset voltage value; if the current gear shift signal is determined to be the fourth signal, the drive stops when the voltage value of the gear signal increases to the fourth preset voltage value.

[0093] In one 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.

[0094] The first calculation formula is shown in Formula 1:

[0095] ;

[0096] in, This indicates the first preset voltage value. The lower limit of the forward gear. The upper limit of forward gears, Represents a constant.

[0097] The second calculation formula is shown in Formula 2:

[0098] ;

[0099] in, This indicates the second preset voltage value. This indicates the lower limit of the neutral position. This indicates the upper limit of the neutral position. Represents a constant.

[0100] The third calculation formula is shown in Formula 3:

[0101] ;

[0102] in, This indicates the third preset voltage value. This indicates the lower limit of the reverse gear. This indicates the upper limit of the reverse gear.

[0103] The fourth calculation formula is shown in Formula 4:

[0104] ;

[0105] in, This indicates the fourth preset voltage value.

[0106] Below, we use the following preset values: first, 100%; second, -50%; third, -100%; and fourth, 50%. It is 20%. The specific implementation of this application will be illustrated using 80% as an example.

[0107] The process of driving at 100% duty cycle acquires the gear position signal. The acquired gear position signal is differentiated to obtain the signal change rate. When the signal change rate slows down significantly (corresponding to a first preset change rate), the corresponding voltage value is the lower limit of the forward gear. When the signal change rate no longer changes (corresponding to a second preset change rate), the average value of the acquired gear position signal voltage is calculated, and the resulting first average value is determined as the upper limit of the forward gear.

[0108] The duty cycle is driven to -50% to collect the gear position signal. 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 (corresponding to the signal change rate being equal to the first preset change rate), the corresponding voltage value is the upper limit value of neutral.

[0109] The gear position signal is acquired during the process of driving the duty cycle to -100%. The acquired gear position signal is differentiated to obtain the signal change rate. When the signal change rate slows down significantly (corresponding to the signal change rate equaling the first preset change rate), the corresponding voltage value is the upper limit value for downshifting. When the signal change rate no longer changes (corresponding to the signal change rate equaling the second preset change rate), the average value of the acquired gear position signal voltage value is calculated, and the obtained second average value is determined as the lower limit value for downshifting.

[0110] The gear position signal is acquired during the process of driving the duty cycle to 50%. The acquired gear position signal is differentiated to obtain the signal change rate of the gear position signal. When the signal change rate slows down significantly (corresponding to the signal change rate being equal to the first preset change rate), the corresponding voltage value is the lower limit value of neutral.

[0111] Specifically, each gear corresponds to a range and is a fixed value. To prevent incomplete gear shifting, a sufficiently large and long driving force is required to ensure a successful gear shift in one go. In addition, due to the inertia of the gear shifting mechanism, excessive driving force can easily cause impacts on the mechanical dead zone of the gear shifting mechanism, affecting its service life. Therefore, this application uses a 2 / 8 drive method for drive processing.

[0112] With the current gear shift signal determined to be the first signal, a positive duty cycle is applied. As the drive time increases, the gear actuator begins to move, and the voltage value of the gear signal gradually increases. When the voltage value increases to... When the drive stops, and the current gear shift signal is determined to be the second signal, the duty cycle is set to a negative value. As the drive time increases, the gear actuator begins to move, and the voltage value of the gear signal gradually decreases. When the voltage value decreases to... When the drive stops, and the current gear shift signal is determined to be the third signal, the duty cycle is set to a negative value. As the drive time increases, the gear actuator begins to move, and the voltage value of the gear signal gradually decreases. When the voltage value decreases to... When the drive stops, and the current gear shift signal is determined to be the fourth signal, the duty cycle is set to a positive value. As the drive time increases, the gear actuator begins to move, and the voltage value of the gear signal gradually increases. When the voltage value increases to... When that happens, the drive stops.

[0113] In one specific embodiment, after all gear shifting signals corresponding to the current gear shift self-learning have been executed, the number of lift-off operations is reset to zero.

[0114] Specifically, as gears are used, they will wear out, causing the gears to change. Therefore, at the beginning of each driving cycle, shift self-learning will only be performed if the shift self-learning conditions are met. After shift self-learning is completed, the number of lift-up operations will be reset to zero so that the number of lift-up operations can be recalculated.

[0115] This application considers the cumulative effect of gear signal wear, self-learns the range of different gears, and uses the 80 / 20 rule to determine whether the engine gear is driven in the correct position, avoiding situations of insufficient or excessive gear drive. Furthermore, it uses the number of lifting operations as the trigger condition for gear shift self-learning, avoiding frequent triggering of gear shift self-learning, reducing wear on the engine shifting mechanism, and improving its service life.

[0116] This application embodiment also provides a gear voltage determination device for a ship engine shifting mechanism. The specific implementation of this device can be found in the description of the gear voltage determination method for the ship engine shifting mechanism; details that are repeated will not be repeated here. As shown in Figure 2, the device includes:

[0120] The iteration module 203 is used to obtain the next gear shift signal and perform a voltage value determination process based on the next gear shift signal until all gear shift signals corresponding to the current gear shift self-learning have been executed.

[0121] Throughout the entire process of a gear shift self-learning, the gear shift self-learning conditions must be continuously met.

[0122] In one specific embodiment, the gear shifting signal includes: a first signal for indicating shifting from neutral to drive, a second signal for indicating shifting from drive to neutral, a third signal for indicating shifting from neutral to reverse, and a fourth signal for indicating shifting from reverse to neutral.
