[0058] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0059] This application provides a control method for an outboard motor. When the temperature of the outboard motor's driver and / or motor is too high, the control method can obtain the rated power of the outboard motor and then activate the power reduction mode of the outboard motor, thereby realizing the over-temperature protection function of the outboard motor and improving the user experience.

[0060] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] like Figure 1 As shown, Figure 1 This is a flowchart illustrating the first embodiment of the outboard motor control method provided in this application.

[0062] The specific steps of the outboard motor control method in this embodiment are as follows:

[0063] Step S11: Obtain the first temperature of the driver and the second temperature of the motor.

[0064] Please see Figure 2 , Figure 2 This is a schematic diagram showing the connection between the battery, driver, and motor of the outboard motor provided in this application. Figure 2 As shown, battery 101 is connected to driver 103, and driver 103 is connected to motor 104. The DC power output from battery 101 is supplied to driver 103, which converts the DC power from battery 101 into three-phase AC power via an inverter to power motor 104. Since both driver 103 and motor 104 draw a large current from battery 101, the main heat-generating components of the outboard motor are driver 103 and motor 104.

[0065] Optionally, the outboard motor control unit may include two temperature sensors, which acquire a first temperature of the driver 103 and a second temperature of the motor 104, respectively. The outboard motor control unit also includes a controller connected to both temperature sensors and capable of acquiring the first and second temperatures from the sensors. In one example, the controller may be a microcontroller unit (MCU).

[0066] Step S12: Determine whether the first temperature is within the first preset temperature range and whether the second temperature is within the second preset temperature range.

[0067] The controller can determine whether the first temperature is within a first preset temperature range and whether the second temperature is within a second preset temperature range based on the first temperature of the driver 103 and the second temperature of the motor 104.

[0068] It should be noted that the first preset temperature range is the temperature range within which the driver 103 needs to reduce power, and the second preset temperature range is the temperature range within which the motor 104 needs to reduce power. When the first temperature is within the first preset temperature range and the second temperature is within the second preset temperature range, the process proceeds to step S13. Furthermore, the first preset temperature range in this application can be greater than the first power reduction temperature of the driver 103. The first power reduction temperature can be the over-temperature protection value of the driver 103 minus the first adjustment temperature value. The adjustment temperature value can be 10°C, but is not limited to this. In one example, the adjustment temperature value can range from [5°C to 15°C]. The second preset temperature range in this application can be greater than the second power reduction temperature of the motor 104. The second power reduction temperature can be the over-temperature protection value of the motor 104 minus the second adjustment temperature value. The adjustment temperature value can be 10°C, but is not limited to this. In one example, the adjustment temperature value can range from [5°C to 15°C]. The over-temperature protection values ​​of the driver 103 and the motor 104 are determined by the characteristics of the driver 103 and the motor 104, respectively. Users can also set the preset temperature range according to the specific type of outboard motor or actual application.

[0069] Step S13: When the first temperature is within the first preset temperature range and the second temperature is within the second preset temperature range, obtain the first given power of the driver and the second given power of the motor.

[0070] When the first temperature is within the first preset temperature range and the second temperature is within the second preset temperature range, it indicates that the outboard motor needs to be turned on in power reduction mode to prevent the outboard motor driver 103 and the outboard motor 104 from being affected by excessive temperature.

[0071] In other embodiments, when the first temperature of the driver 103 is within the first preset temperature range and the second temperature of the motor 104 is outside the second preset temperature range, it indicates that the temperature of the driver 103 is too high while the temperature of the motor 104 is normal. At this time, the controller can obtain the first given power of the driver 103, thereby realizing the power reduction operation of the outboard motor and preventing the temperature of the driver 103 from being too high and affecting the operation of the outboard motor.

[0072] In other embodiments, when the first temperature of the driver 103 is outside the first preset temperature range while the second temperature of the motor 104 is within the second preset temperature range, it indicates that the temperature of the motor 104 is too high while the temperature of the driver 103 is normal. At this time, the controller can obtain the second given power of the motor 104, thereby realizing the power reduction operation of the outboard motor and preventing the temperature of the motor 104 from being too high and affecting the operation of the outboard motor.

[0073] Step S14: Select the smaller of the first given power and the second given power as the given power of the outboard motor, so that the outboard motor operates in a reduced power mode.

[0074] The controller can compare the first and second given power and select the smaller one as the given power of the outboard motor. This allows the outboard motor to operate in a reduced power mode at the given power, thereby providing protection when the temperature of the outboard motor driver 103 and the motor 104 is too high. In this state, the outboard motor can operate normally without activating the shutdown mode, and there will be no sudden shutdown during full power operation, resulting in a better user experience.

[0075] In other embodiments, when the first temperature of the driver 103 is within a first preset temperature range while the second temperature of the motor 104 is outside a second preset temperature range, the temperature of the driver 103 is too high while the temperature of the motor 104 is normal. The controller can directly use the first set power of the driver 103 as the set power of the outboard motor. In this way, the outboard motor can realize the protection function when the temperature of the driver 103 is too high, and the outboard motor can operate normally in this state without activating the shutdown mode. This prevents the outboard motor from suddenly stopping during full-power operation, resulting in a better user experience.

[0076] In other embodiments, when the first temperature of the driver 103 is outside the first preset temperature range while the second temperature of the motor 104 is within the second preset temperature range, the temperature of the driver 103 is normal, but the temperature of the motor 104 is too high. The controller can directly use the second set power of the motor 104 as the set power of the outboard motor. In this way, the outboard motor can realize the protection function when the temperature of the motor 104 is too high. In this state, the outboard motor can operate normally without activating the shutdown mode, and there will be no situation where the outboard motor suddenly stops during full-power operation, resulting in a better user experience.

[0077] It should be noted that the first given power in this application is the maximum given input power of the driver 103. When the first temperature of the driver 103 is within the first preset temperature range, the first given power is less than the rated power of the driver 103 (that is, the full power of the driver 103). The second given power in this application is the maximum given input power of the motor 104. When the second temperature of the motor 104 is within the second preset temperature range, the second given power is less than the rated power of the motor 104 (that is, the full power of the motor 104).

[0078] Optionally, the controller may obtain a first power reduction function of the outboard motor and obtain a first given power of the outboard motor based on the first power reduction function of the outboard motor.

[0079] Optionally, the controller may obtain a second power reduction function of the outboard motor and obtain a second given power of the outboard motor based on the second power reduction function of the outboard motor.

[0080] In one embodiment, the first power reduction function and the second power reduction function are linear functions. For example, see [link to example]. Figure 3 as well as Figure 4 , Figure 3 This is a schematic diagram showing the relationship between the input power and temperature of the driver provided in this application; Figure 4 This is a schematic diagram showing the relationship between the input power and temperature of the motor provided in this application.

[0081] like Figure 3 As shown, the over-temperature protection value of driver 103 is Tq; the starting power reduction point of driver 103 (i.e., the first power reduction temperature) is Tq-10, and the full power of driver 103 is P1. Specifically, when the first temperature of driver 103 is less than or equal to the first power reduction temperature, the first setpoint power of driver 103 is P1. As the first temperature of driver 103 continues to rise from Tq-10, the first setpoint power of driver 103 decreases linearly. When the first temperature reaches Tq, the first setpoint limit is P1 / 2.

[0082] like Figure 4 As shown, the over-temperature protection value of motor 104 is Td; the starting point for power reduction of motor 104 (i.e., the second power reduction temperature) is Td-10, and the full power of motor 104 is P2. Specifically, when the second temperature of motor 104 is less than or equal to the second power reduction temperature, the second setpoint power of motor 104 is P2. As the second temperature of motor 104 continues to rise from Td-10, the second setpoint power of motor 104 decreases linearly, and when it reaches Td, the second setpoint power is limited to P2 / 2.

[0083] It is understandable that when the driver 103 and the motor 104 reach the temperature of the power limit range at the same time, the smaller value between the power limit output value of the driver 103 and the power limit output value of the motor 104 is selected as the maximum power limit of the outboard motor. At this time, the outboard motor can operate in a reduced power mode, thereby realizing the over-temperature protection function of the outboard motor.

[0084] In another embodiment, the first power reduction function and the second power reduction function are nonlinear functions. For example, such as... Figure 5 as well as Figure 6 As shown, Figure 5 This is a schematic diagram of a second embodiment of the relationship between input power and temperature of the driver provided in this application; Figure 6 This is a schematic diagram of a second embodiment of the relationship between the input power and temperature of the motor provided in this application. During the power reduction phase of the driver 103 and the power reduction phase of the motor 104, the relationship between the input power (i.e., the first given power) of the driver 103 and the first temperature of the driver 103 can also be a quadratic or cubic curve relationship, and the relationship between the input power (i.e., the second given power) of the motor 104 and the second temperature of the motor 104 can also be a quadratic or cubic curve relationship.

[0085] The over-temperature protection value of driver 103 is Tq*, the starting power derating point of driver 103 (i.e., the first power derating temperature) is Tq*-10, and the full power of driver 103 is P1*. Specifically, when the first temperature of driver 103 is less than or equal to the first power derating temperature, the first setpoint power of driver 103 is P1*. As the first temperature of driver 103 continues to rise from Tq*-10, the first setpoint power of driver 103 decreases curvilinearly. When the first temperature reaches Tq*, the first setpoint power is limited to P1* / 2.

[0086] The over-temperature protection value of motor 104 is Td*. The starting point for power reduction of motor 104 (i.e., the second power reduction temperature) is Td*-10, at which point the full power of motor 104 is P2*. Specifically, when the second temperature of motor 104 is less than or equal to the second power reduction temperature, the second setpoint power of motor 104 is P2*. As the second temperature of motor 104 continues to rise from Td*-10, the second setpoint power of motor 104 decreases curvilinearly. When the second temperature reaches Td*, the second setpoint power of motor 104 is limited to P2* / 2.

[0087] It should be noted that the first power reduction function is not limited to Figure 3 and Figure 5 The two functions shown can also be other functions; similarly, the second power reduction is not limited to... Figure 4 and Figure 6The two functions shown can be other functions as well, and there are no restrictions here. In addition, the first power reduction function and the second power reduction function do not necessarily have to be both linear functions or both nonlinear functions; one can be a linear function and the other a nonlinear function, and there are no restrictions here either.

[0088] It can be understood that the input power of the driver 103 and the input power of the motor 104 have the following relationship:

[0089] P 驱动器 =k1*P 驱动器 +(1-k1)*P 驱动器 (1)

[0090] Among them, P 驱动器 k1*P is the input power of driver 103. 驱动器 The heat dissipation power of driver 103; (1-k1)*P 驱动器 This is the output power of the driver 103, which is also the input power of the motor 104.

[0091] Furthermore, the heating power of motor 104 is (1-k1)*k2*P 驱动器 Wherein, k1 and k2 are the heat generation coefficients of the driver 103 and the motor 104, respectively.

[0092] In addition, the input power P of driver 103 驱动器 It can be obtained from the following formula:

[0093] P 驱动器 =UI (2)

[0094] Where U is the voltage of battery 101; I is the output current of battery 101. Furthermore, the controller can obtain the voltage of battery 101 by detecting the voltage across the positive and negative terminals of battery 101 through a voltage sensor, and obtain the output current of battery 101 by detecting the bus current of battery 101 through a current sensor.

[0095] As can be seen from the above formulas (1) and (2), the heat generation power of the driver 103 and the motor 104 can be controlled by controlling the input power of the driver 103 and the input power of the motor 104, that is, the temperature of the driver 103 and the temperature of the motor 104 can be controlled.

[0096] Please see Figure 2 and Figure 7 , Figure 7 This is a flowchart illustrating the second embodiment of the outboard motor control method provided in this application. Figure 7As shown, step S31 marks the start of the entire process. Step S32 involves the controller acquiring the first temperature of the driver 103 and the second temperature of the motor 104. Step S33 involves the controller determining whether the first temperature of the driver 103 is within a first preset temperature range. If yes, proceed to step S35: execute the high-temperature power reduction function (i.e., the first power reduction function) of the driver 103 to obtain the first given power of the driver 103; otherwise, proceed to step S32. Step S34 involves the controller determining whether the second temperature of the motor 104 is within a second preset temperature range. If yes, proceed to step S36: execute the high-temperature power reduction function of the motor 104 to obtain the second given power of the motor 104; otherwise, proceed to step S32. After acquiring the first and second given power, proceed to step S37: the outboard motor control system selects the smaller value between the first given power of the driver 103 and the second given power of the motor 104 as the given power of the outboard motor. When the first temperature of the driver 103 is within a first preset temperature range and the second temperature of the motor 104 is outside a second preset temperature range, a high-temperature power reduction function for the driver is executed to obtain a first given power for the driver 103, and this first given power is used as the given power for the outboard motor. When the second temperature of the motor 104 is within a second preset temperature range and the first temperature of the driver 103 is outside the first preset temperature range, a high-temperature power reduction function for the motor 104 is executed to obtain a second given power for the motor 104, and this second given power is used as the given power for the outboard motor. This achieves power reduction mode operation of the outboard motor, thereby realizing the over-temperature protection function of the outboard motor.

[0097] In this embodiment, the temperature of the driver 103 and the temperature of the motor 104 can be considered simultaneously to determine whether the outboard motor needs to be turned on in a power reduction mode. If the outboard motor needs to be turned on in a power reduction mode, the given power of the driver 103 and the given power of the motor 104 are compared to select the rated power of the outboard motor, thereby realizing the over-temperature protection function of the outboard motor. In this state, the outboard motor can operate normally without the need to turn on the shutdown mode, and there will be no situation where the outboard motor suddenly stops during full-power operation, resulting in a better user experience.

[0098] Continue reading Figure 2 as well as Figure 8 , Figure 8 This is a flowchart illustrating the third embodiment of the outboard motor control method provided in this application. The outboard motor provided in this application may further include a battery 101, which is connected to a driver 103. The outboard motor control method proposed in this application also includes:

[0099] Step S21: Obtain the battery voltage.

[0100] The controller can obtain the voltage of battery 101.

[0101] Understandably, when the battery 101 is low on power, the outboard motor needs to switch to a reduced power mode. Therefore, based on the above embodiments, this application considers not only the temperature of the driver 103 and the temperature of the motor 104, but also the power level of the battery 101 to comprehensively determine whether the outboard motor needs to switch to a reduced power mode.

[0102] Step S22: Determine whether the voltage is less than the preset voltage.

[0103] The outboard motor control device can determine whether the battery 101 voltage is lower than a preset voltage based on the acquired battery 101 voltage. The preset voltage includes the undervoltage of the battery 101 and an adjustment voltage superimposed on the undervoltage.

[0104] It should be noted that the undervoltage of battery 101 is determined by the characteristics of battery 101 itself. Furthermore, the adjustment voltage in this application can range from [2V, 4V], for example, it can be 2V, 3V, or 4V, etc., and is not limited here. In one specific embodiment, when the adjustment voltage is 3V, that is, the preset voltage is (undervoltage + 3)V, the remaining capacity of battery 101 is approximately 10%-20% of the total capacity.

[0105] It should also be noted that the preset voltage can be pre-set or determined based on the undervoltage obtained from the battery 101 during the execution of the solution in this application. Specifically, for a battery 101 that can communicate with the driver 103, the controller can obtain the undervoltage of the battery 101 through the communication line, and then obtain a preset voltage based on the obtained undervoltage and a preset adjustment voltage. For a battery 101 that cannot communicate with the driver 103, the undervoltage of the battery 101 can be set via the handle 102 before use. For example, the undervoltage of the battery 101 can be set according to the display screen and buttons on the handle 102. Thus, during the execution of the solution of this application, the preset voltage can be obtained based on the undervoltage set via the handle 102 and the preset adjustment voltage. For a battery 101 that cannot communicate with the driver 103, the preset settings of the battery 101 can also be set via the handle 102 before use. For example, the preset voltage of the battery 101 can be set according to the display screen and buttons on the handle 102. Thus, during the execution of the solution of this application, the determination of whether the outboard motor enters the power reduction mode can be directly based on the set preset voltage.

[0106] Step S23: If so, determine the third given power output of battery 101 based on the voltage.

[0107] Please see Figure 9 , Figure 9This is a schematic diagram illustrating the voltage and power relationship of the battery 101 provided in this application. When the voltage of the battery 101 is lower than the preset voltage, it indicates that the battery 101 is about to enter an undervoltage state, at which point the outboard motor needs to activate the reduced power mode. Furthermore, the controller can determine the third given power output of the battery 101 based on the voltage of the battery 101, and then determine the given power of the outboard motor based on the third given power, so that the outboard motor operates in the reduced power mode.

[0108] like Figure 9 As shown, the voltage of battery 101 is V, and the preset voltage value of battery 101 is V1. V and V1 correspond to the power of battery 101 as P3 and P3 / 2, respectively. When the outboard motor is in reduced power mode, the relationship between the voltage and power of battery 101 is linear.

[0109] Step S24: When the first temperature of the driver 103 is within the first preset temperature range and the second temperature of the motor 104 is within the second preset temperature range, the minimum value among the first given power, the second given power and the third given power is selected as the given power of the outboard motor so that the outboard motor operates in a reduced power mode.

[0110] Based on the first and second embodiments, the controller can compare the acquired first, second, and third given power to select the minimum as the given power of the outboard motor. This allows the outboard motor to operate in a reduced-power mode at that given power. This embodiment can simultaneously provide protection when the temperatures of the outboard motor's driver 103 and motor 104 are too high, and the battery 101 is about to reach an undervoltage state. In this state, the outboard motor can still operate normally without activating the shutdown mode, preventing sudden shutdowns during full-power operation and providing a better user experience.

[0111] In other embodiments, when the first temperature of the driver 103 is within a first preset temperature range, while the second temperature of the motor 104 is outside a second preset temperature range, and the voltage of the battery 101 is less than a preset voltage, the controller can compare the first given power of the driver 103 with the third given power output by the battery 101, and select the smaller one as the given power of the outboard motor. This allows the outboard motor to operate in a reduced-power mode, while also providing protection when the temperature of the driver 103 is too high or the battery 101 is about to reach an undervoltage state. In this state, the outboard motor can operate normally without activating the shutdown mode, preventing sudden shutdowns during full-power operation and providing a better user experience.

[0112] In other embodiments, when the first temperature of the driver 103 is outside the first preset temperature range, while the second temperature of the motor 104 is within the second preset temperature range, and the voltage of the battery 101 is less than a preset voltage, the controller can compare the second given power of the motor 104 with the third given power output by the battery 101, and select the smaller one as the given power of the outboard motor. This allows the outboard motor to operate in a reduced-power mode, while also providing protection when the motor 104 temperature is too high or the battery 101 is about to reach an undervoltage state. In this state, the outboard motor can operate normally without activating the shutdown mode, preventing sudden shutdowns during full-power operation and providing a better user experience.

[0113] The outboard motor control method proposed in this application can simultaneously consider the temperature of the driver 103, whether the temperature of the motor 104 is too high, and whether the voltage of the battery 101 is low. Then it determines whether the outboard motor needs to activate the power reduction mode. If the outboard motor needs to activate the power reduction mode, it compares at least two of the given power of the driver 103, the given power of the motor 104, and the given power output of the battery 101 to select the rated power of the outboard motor. This realizes the over-temperature protection function and the under-voltage protection function of the outboard motor. Moreover, the outboard motor can still operate normally under the over-temperature and / or impending under-voltage conditions without activating the shutdown mode. It will not cause the outboard motor to suddenly stop during full-power operation, resulting in a better user experience.
