Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
One embodiment of the present invention relates to a method for preventing overheating of an electric rear wing, which is applied to a vehicle, and the flow of the method is shown in fig. 1, and comprises the following steps:
Specifically, the motor running state in the electric tail wing comprises a normal motor rotation state, a motor locked-rotor state and a motor static state. In addition, in practical applications, the operation state of the motor may further include other parameters, such as a rotation speed, a power, a voltage value, a current value, and the like of the motor, which is not specifically limited in the embodiment of the present invention.
Specifically, the first counting strategy may be a linear increase, a gradient increase, or other counting strategies, which are not specifically limited in this embodiment of the present invention. Wherein the linear increase is such that the increase in the value in the counter remains unchanged. Specifically, the counter may increase the first value according to a certain time interval, where both the time interval and the first value may be adaptively adjusted in practical application, for example, the time interval may be 10ms or 15ms, and the first value may be 2, 5, or 10, which is not specifically limited in this embodiment of the present invention. In addition, the embodiment of the invention can also change the first value according to the running state of the motor, so that the heat productivity of the motor in normal rotation shown by the first value is more accurate, for example, the first value is increased under the condition that the power of the motor is larger, and the first value is reduced under the condition that the power of the motor is lower. When the motor normally rotates, the value in the counter is continuously accumulated at the speed of increasing the first value at each regular interval. The gradient increment, i.e. the increase in the number of counters, may be changed, in particular, the increase increases or decreases with time. For example, the value in the counter is incremented at certain intervals, by 2 in a first interval, by 3 in a second interval, by 4 in a third interval, and so on. In addition, in this embodiment, a function of the speed increase and the time may be established, or other counting strategies may be formulated according to actual situations, which is not specifically limited in this embodiment of the present invention.
103, if the motor is judged to be in a locked-rotor state according to the running state of the motor, controlling the counter to increase a second numerical value according to a second counting strategy; the second numerical value represents a calorific value when the motor is locked.
Specifically, the second counting strategy may be a linear increment, a gradient increment, or other counting strategies, which are not specifically limited in this embodiment of the present invention. Wherein the linear increase is such that the increase in the value in the counter remains unchanged. Specifically, the counter may increase the second value at a certain time interval, where the second value may be adaptively adjusted in practical applications, for example, the second value may be 50, 80, 100, and the like, which is not specifically limited in this embodiment of the present invention. In addition, the embodiment of the present invention may change the second value according to the motor operating state, for example, increase the second value when the motor current is large (the heat generation amount is large), and decrease the second value when the motor current is small (the heat generation amount is small). In a normal state, the second value is larger than the first value because the heat generation amount is larger than the heat generation amount in the normal rotation when the motor is locked. The gradient increase in this embodiment is similar to the specific description in step 102, and will not be described in detail here. In addition, in this embodiment, a function of the speed increase and the time may be established, or other counting strategies may be formulated according to actual situations, which is not specifically limited in the embodiment of the present invention.
104, if the value in the counter is increased to a first target value, prohibiting the motor from rotating for the next time; wherein the first target value is determined by the maximum heat that can be tolerated by the electrical tail.
In the present embodiment, the maximum heat that the electric tail can bear is determined not only by the material and structure of the electric tail itself, but also by the ambient temperature of the motor. In particular, the first target value may be adjusted according to the ambient temperature of the electrical machine, for example 60000 in the case of 20 ℃ and 50000 in the case of 30 ℃. Of course, the above is only an example, and the specific value of the first target value and the corresponding ambient temperature of the motor may be adjusted according to an actual situation, which is not specifically limited in the embodiment of the present invention. In the present embodiment, when the value in the counter reaches the first target value after the motor is normally rotated or the motor is stopped and accumulated, it indicates that the electric tail has reached the maximum tolerable heat, at which time the motor is prohibited from performing the next movement, but the motor is allowed to continue to rotate until the end of the movement of the electric tail.
In the embodiment of the invention, the heating values of the rotation and the locked rotor of the motor are expressed in the form of numerical values, and the maximum heat degree which can be borne by the electric tail wing, namely the first target numerical value, can be determined according to the ambient temperature, so that the electric tail wing does not move next time when the electric tail wing has the risk of overheating, and the motor damage caused by overheating of the electric tail wing is effectively prevented. In addition, the invention can not stop the motion of the electric tail immediately when the first target value is reached, but forbids the next motion of the electric tail, thereby effectively preventing the electric tail from suddenly stopping in the motion to generate faults.
In addition, as shown in fig. 2, the method for preventing the electric rear wing from being overheated may further include:
In this embodiment, the third counting strategy may be a linear reduction strategy, a gradient reduction strategy, or another counting strategy, which is not specifically limited in this embodiment of the present invention. Wherein the linear reduction is such that the rate of reduction of the value in the counter remains unchanged. Specifically, the counter may increase the first value according to a certain time interval, where the time interval may specifically be 10ms, 20ms, and the like, and this is not specifically limited in the embodiment of the present invention. The third value represents the heat dissipation amount of the motor in a certain interval, and may be specifically 5, 8, 10, and the like, and may be adjusted according to different situations in practical application, for example, the third value is larger when the ambient temperature of the motor is higher, and the third value is smaller when the ambient temperature of the motor is lower, which is not specifically limited in the embodiment of the present invention. The rate at which the gradient decreases, i.e., the value in the counter decreases, may vary, and specifically, the rate of decrease may increase or decrease with time. For example, the value in the counter is decremented at intervals, by 2 in a first interval, by 3 in a second interval, by 4 in a third interval, and so on. In addition, in this embodiment, a function of the reduction speed and the time may be established, or other counting strategies may be formulated according to actual situations, which is not specifically limited in this embodiment of the present invention.
And 106, if the value in the counter is reduced to a second target value, allowing the motor to rotate next time.
In this embodiment, the second target value is the thermal limit at which the electric tail can safely make the next movement. Specifically, the second target value may be associated with the first target value, for example, 50%, 40% or the like of the first target value, or may be directly and specifically determined to be 30000, 25000 or the like regardless of the first target value, which is not specifically limited in this embodiment of the present invention. In addition, the second target value may be related to an ambient temperature of the motor in the electric rear wing, for example, 20000 at 20 ℃, 28000 at 30 ℃ and the like, which is not particularly limited in the embodiment of the present invention.
In the present embodiment, by continuously decreasing the value at a constant speed in the counter when the electric tail motor is stationary and setting the second target value, the motor is allowed to perform the next movement after triggering the overheat protection when the condition that the motor can perform the next safe movement is satisfied, and the motor is prevented from being permanently stopped due to overheat.
It should be noted that, the execution sequence of the steps in the steps 101-106 may be adjusted in practical applications, and this is not specifically limited in the embodiment of the present invention.
Optionally, the method for preventing overheating of the electric rear wing further includes:
judging whether the motor rotates according to the running state of the motor, if so, turning off the original overheat protection function of the electric tail wing controller, and if not, turning on the original overheat protection function of the electric tail wing controller; wherein the original overheat protection function of the electric empennage comprises: when the thermal protection condition is satisfied, the motor is immediately stopped.
In the embodiment, the original overheat protection function of the electric tail controller is turned off when the motor rotates, so that the method for preventing the electric tail from overheating is not influenced by the original overheat protection function, namely, the motor in the electric tail cannot stop rotating immediately even if the original overheat protection condition is met, and the damage or the fault caused by sudden stop of the electric tail in the operation is prevented. In addition, the invention can be matched with the overheating protection function of the original electric empennage controller, so that the overheating protection effect is improved, namely, when the motor is static, the original overheating protection function is running, and when the original overheating protection condition is achieved, the motor is prohibited from rotating, so that the purpose of overheating protection is achieved.
Another embodiment of the present invention provides a flow chart of a method for preventing overheating of an electric rear wing, as shown in fig. 3:
firstly, judging whether a motor in the electric empennage is driven or not, namely whether the electric empennage is executing movement or not, if not, reducing the numerical value in the counter by 1 every 10ms, and if so, judging whether the motor is locked. The condition that the motor is driven comprises normal rotation of the motor and motor stalling. Judging whether the motor is locked up includes: when the motor is locked, the value in the counter is increased by 50 every 10ms, and the value in the counter is increased by 2 every 10ms when the motor is normally rotated. And then judging whether the numerical value in the counter exceeds 12000, if so, prohibiting the next electric tail wing movement, if not, judging whether the numerical value in the counter is lower than 60000, and if so, allowing the next electric tail wing movement.
It should be noted that various numerical values in the present embodiment may be adjusted according to actual situations, and this is not particularly limited in the embodiment of the present invention.
