Description

Technical Field

[0001] The present application relates to the technical field of vehicle clutches, and in particular to a vehicle clutch protection method, device, equipment and readable storage medium. Background Art

[0002] In the vehicle power system, the clutch plays the role of transmitting and interrupting the engine power. Semi-clutch is a state when the clutch is operated in a manual transmission vehicle during driving. The driver steps on the clutch pedal to gradually reduce the pressure on the clutch pressure plate, causing the active disc and the driven disc to rotate and slip.

[0003] Semi-clutch is usually used in the process of vehicle starting, so that the engine power is gradually transferred to the wheels, thereby improving the starting stability. In the semi-clutch state, the sliding friction between the clutch active plate and the driven plate, the heat generated by the friction will aggravate the clutch wear, so it is necessary to appropriately limit the semi-clutch state to protect the clutch.

[0004] In the related art, during the vehicle starting process, the engine torque is limited to different degrees for each vehicle gear, thereby limiting the sliding power in the semi-clutch state. However, this limitation method cannot well judge whether the clutch is in a semi-clutch state exceeding the safety threshold, which will excessively limit the starting power, resulting in weak starting and reducing the driving experience. Summary of the invention

[0005] The present application provides a vehicle clutch protection method, device, equipment and readable storage medium, which can solve the technical problem of inappropriate semi-clutch state restriction leading to weak starting in the prior art.

[0014] Furthermore, in one embodiment, after the step of setting the target time, the following steps are further included:

[0021] If the current gear position of the vehicle is 1st gear or reverse gear, then detecting whether the duration of the current semi-clutch working condition is greater than a second preset threshold;

[0022] If the duration of the semi-linkage working condition is longer than the second preset threshold, a second warning prompt is output;

[0023] If the duration of the current semi-clutch working condition is less than or equal to the second preset threshold, detecting whether the clutch speed difference at the current moment is greater than the third preset threshold;

[0024] If the clutch speed difference at the current moment is greater than the third preset threshold, a third warning prompt is output.

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0042] In a first aspect, an embodiment of the present application provides a vehicle clutch protection method.

[0043] Figure 1 A schematic flow chart of a vehicle clutch protection method in an embodiment of the present application is shown.

[0044] Reference Figure 1 In one embodiment, the vehicle clutch protection method comprises the following steps:

[0045] S1. After the vehicle engine is started, determine whether the clutch is in a semi-clutch state.

[0046] Figure 2 A structural schematic diagram of a vehicle power system is shown.

[0047] Reference Figure 2 The vehicle power system includes an engine 1, a clutch 2, a gearbox 3, a transmission shaft 4 and a driving wheel 5. The output shaft of the engine 1 is connected to the driving plate 21 of the clutch 2, the driven plate 22 of the clutch 2 is connected to the input shaft of the gearbox 3, and the output shaft of the gearbox 3 is connected to the driving wheel 5 through the transmission shaft 4. When the driving plate 21 and the driven plate 22 of the clutch 3 are completely separated, the power of the engine 1 will not be transmitted to the gearbox 3. When the driving plate 21 and the driven plate 22 of the clutch 3 are completely engaged, the rotation speeds of the driving plate 21 and the driven plate 22 are equal, and the power of the engine 1 is fully transmitted to the gearbox 3. When the driving plate 21 and the driven plate 22 of the clutch 3 are neither completely engaged nor completely separated, the rotation speed of the driving plate 21 is greater than the rotation speed of the driven plate 22, and part of the power of the engine 1 is transmitted to the gearbox 3, and part of it is consumed by the friction between the driving plate 21 and the driven plate 22. This state is called a semi-clutch state.

[0048] The clutch speed difference is the speed difference between the clutch active disc and the driven disc. The speed of the active disc is equal to the engine speed, and the speed of the driven disc is equal to the speed of the gearbox input shaft.

[0049] Furthermore, in one embodiment, the step of determining whether the clutch is in a semi-clutch state comprises:

[0050] If the vehicle gear at the current moment is not neutral, the transmission input shaft speed at the current moment is greater than the fifth preset threshold, and the clutch speed difference at the current moment is greater than the sixth preset threshold, it is determined that the clutch is in a semi-clutch state at the current moment.

[0051] Through this embodiment, it is possible to accurately determine whether the clutch is in a semi-clutch state.

[0052] S2. If the clutch is in a semi-clutch state, the first condition is met, and at least one of the second condition, the third condition and the fourth condition is met, then a warning prompt is output, wherein the first condition is that the accumulated sliding friction work of this semi-clutch working condition is greater than the first preset threshold value, the second condition is that the vehicle gear position at the current moment is not 1st gear and reverse gear, the third condition is that the duration of this semi-clutch working condition is greater than the second preset threshold value, and the fourth condition is that the clutch speed difference at the current moment is greater than the third preset threshold value.

[0053] In this embodiment, if the clutch is in a semi-clutched state at a certain moment and is not in a semi-clutched state at the previous moment, then this moment is called the starting moment of a single semi-clutched working condition; if the clutch is not in a semi-clutched state at a certain moment and is in a semi-clutched state at the previous moment, then this moment is called the ending moment of a single semi-clutched working condition; the starting moment to the ending moment represents a completed semi-clutched working condition; the current moment between the starting moment and the ending moment represents an ongoing semi-clutched working condition.

[0054] This semi-linked working condition belongs to the ongoing semi-linked working condition. The accumulated sliding friction work of this semi-linked working condition refers to the accumulated sliding friction work from the start time of this semi-linked working condition to the current time, and the duration of this semi-linked working condition refers to the interval from the start time of this semi-linked working condition to the current time.

[0055] For example, the clutch is not in the semi-clutch state at time 0, is in the semi-clutch state from time 1 to time 10, is not in the semi-clutch state from time 11 to time 14, and is in the semi-clutch state from time 15 to the current time. Then, time 1 to time 10 represent a completed semi-clutch working condition, and time 15 to the current time represent an ongoing semi-clutch working condition, that is, this semi-clutch working condition.

[0056] For example, the calculation formula of the accumulated sliding friction work is:

[0057]

[0058] Among them, W is the accumulated sliding work, T is the accumulated total time, n e is the real-time engine torque, ω e is the real-time engine speed, ω c It is the real speed of the gearbox input shaft.

[0059] The first condition is the basic condition for early warning, which means that the accumulated friction work of this semi-clutch working condition exceeds the limit, and the risk of damage to the clutch is high. The second, third and fourth conditions are additional conditions for early warning, which represent three possible reasons for the accumulated friction work exceeding the limit: when the vehicle gear is not 1st gear or reverse gear, the engine torque is large, resulting in high friction power and rapid growth of accumulated friction work; the duration of this semi-clutch working condition is long, and the accumulated friction work continues to grow; the clutch speed difference is large, resulting in high friction power and rapid growth of accumulated friction work. Therefore, on the basis of satisfying the first condition, if at least one of the second, third and fourth conditions is also met, an early warning will be output, thereby improving the accuracy of judgment.

[0060] In addition, the clutch is protected by using early warning prompts instead of directly limiting the engine speed or torque. After receiving the early warning prompt, the driver can choose the response measures by himself, which has a higher degree of freedom and improves the driving experience. Of course, if the situation does not improve after the early warning prompt, the engine speed or torque can be selectively limited to avoid clutch damage.

[0061] Optionally, warning prompts are output through instruments, voice, lights, etc.

[0062] Therefore, in this embodiment, the accumulated friction work, the real-time vehicle gear position, the duration of the state, and the real-time clutch speed difference in a single semi-clutch working condition are monitored. In a single semi-clutch working condition, if the accumulated friction work exceeds the safety range, and at least one of the real-time vehicle gear position, the duration of the state, and the real-time clutch speed difference exceeds the safety range, the driver will be informed through an early warning that the clutch is vulnerable to damage and needs to be operated in a standardized manner. Through this embodiment, it is comprehensively judged from multiple dimensions whether the clutch is in a semi-clutch working condition that exceeds the safety threshold, and the driver is warned, thereby providing the driver with the maximum degree of free operation space within the range where the clutch is not damaged, thereby improving the driving experience.

[0063] Furthermore, in one embodiment, the vehicle clutch protection method further includes:

[0064] Set target moments;

[0065] At each moment within a preset time after the target moment, if the cumulative sliding friction work from the target moment to the current moment is greater than a fourth preset threshold, an early warning prompt is output, wherein the preset time is greater than the second preset threshold, and the fourth preset threshold is greater than the first preset threshold.

[0066] In this embodiment, for the situation where multiple short semi-clutch operating conditions are experienced within a period of time, relying solely on the detection of the first to fourth conditions may not trigger an early warning. Therefore, a new detection logic is added that does not distinguish between single or multiple semi-clutch operating conditions, and counts the accumulated sliding work within a preset time period, thereby improving the comprehensiveness of the detection and further reducing the risk of clutch damage.

[0067] Furthermore, in one embodiment, the step of setting the target time includes:

[0068] At the start time of each semi-linked working condition, if there is no target time, the current time is used as the target time. If there is a target time and the interval from the target time to the current time is greater than the preset duration, the current time is used as the new target time.

[0069] This embodiment provides a target time setting strategy, which can identify the start time of the first semi-clutch working condition in the starting phase and set it as the target time.

[0070] Furthermore, in one embodiment, after the step of setting the target time, the following steps are further included:

[0071] Setting the first accumulated value at the target time to zero;

[0072] At each moment within a preset time after the target moment, the first accumulated value of the previous moment is added to the product of the friction power of the current moment and the interval between adjacent moments to obtain the first accumulated value of the current moment, and the first accumulated value of the current moment is used as the accumulated friction power from the target moment to the current moment.

[0073] This embodiment provides a method for calculating the accumulated sliding friction work from the target moment to the current moment.

[0074] Optionally, the slip power is equal to the product of the clutch speed difference and the engine torque.

[0075] Further, in one embodiment, if the clutch is in a semi-clutch state, the first condition is satisfied, and at least one of the second condition, the third condition, and the fourth condition is satisfied, the step of outputting a warning prompt comprises:

[0076] If the clutch is in a semi-clutch state, detecting whether the accumulated sliding friction work of this semi-clutch working condition is greater than a first preset threshold;

[0077] If the accumulated sliding friction work of the current semi-clutch working condition is greater than the first preset threshold, then detecting whether the current vehicle gear position is the first gear or the reverse gear;

[0078] If the current gear position of the vehicle is not the 1st gear or the reverse gear, the first warning prompt is output;

[0079] If the current gear position of the vehicle is 1st gear or reverse gear, then detecting whether the duration of the current semi-clutch working condition is greater than a second preset threshold;

[0080] If the duration of the semi-linkage working condition is longer than the second preset threshold, a second warning prompt is output;

[0081] If the duration of the current semi-clutch working condition is less than or equal to the second preset threshold, detecting whether the clutch speed difference at the current moment is greater than the third preset threshold;

[0082] If the clutch speed difference at the current moment is greater than the third preset threshold, a third warning prompt is output.

[0083] In this embodiment, when the clutch is in a semi-clutch state, it is first detected whether the first condition is met. After the first condition is met, it is preferentially detected whether the second condition is met. If the second condition is not met, it is then detected whether the third condition is met. If the third condition is not met, it is then detected whether the fourth condition is met, thereby reducing resource usage.

[0084] Optionally, the first warning prompt, the second warning prompt and the third warning prompt may include different prompt information to inform the driver of the cause of clutch damage.

[0085] For example, the first warning prompt includes a text reminder of "the starting gear is high, and the clutch is prone to burning", the second warning prompt includes a text reminder of "the semi-clutch time is long, and the clutch is prone to burning", and the third warning prompt includes a text reminder of "the semi-clutch speed is high, and the clutch is prone to burning". The first warning prompt, the second warning prompt and the third warning prompt also include a voice reminder of "the clutch is damaged, please follow the prompts and operate in accordance with the standard", and the yellow light on the instrument flashes three times.

[0086] Furthermore, in one embodiment, the vehicle clutch protection method further includes:

[0087] At each moment when the clutch is in the semi-clutch state, the second accumulated value at the previous moment is added to the product of the sliding power at the current moment and the interval between adjacent moments to obtain the second accumulated value at the current moment, and the second accumulated value at the current moment is used as the accumulated sliding power of this semi-clutch working condition;

[0088] When the clutch is not in the semi-engaged state, the second accumulated value is set to zero.

[0089] This embodiment provides a method for calculating the accumulated sliding friction work of this semi-clutch working condition.

[0090] In a second aspect, an embodiment of the present application also provides a vehicle clutch protection device.

[0091] Figure 3 A schematic diagram of the functional modules of a vehicle clutch protection device in one embodiment of the present application is shown.

[0092] Reference Figure 3 In one embodiment, the vehicle clutch protection device comprises:

[0093] The state judgment module 10 is used to judge whether the clutch is in a semi-clutch state after the vehicle engine is started;

[0094] The first warning module 20 is used to output a warning prompt if the clutch is in a semi-clutch state, satisfies the first condition, and satisfies at least one of the second condition, the third condition and the fourth condition, wherein the first condition is that the accumulated sliding work of this semi-clutch working condition is greater than the first preset threshold value, the second condition is that the vehicle gear position at the current moment is not the 1st gear and the reverse gear, the third condition is that the duration of this semi-clutch working condition is greater than the second preset threshold value, and the fourth condition is that the clutch speed difference at the current moment is greater than the third preset threshold value.

[0095] Furthermore, in one embodiment, the vehicle clutch protection device further includes a second early warning module 30, which is used to:

[0096] Set target moments;

[0097] At each moment within a preset time after the target moment, if the cumulative sliding friction work from the target moment to the current moment is greater than a fourth preset threshold, an early warning prompt is output, wherein the preset time is greater than the second preset threshold, and the fourth preset threshold is greater than the first preset threshold.

[0098] Furthermore, in one embodiment, the second early warning module 30 is used to:

[0099] At the start time of each semi-linked working condition, if there is no target time, the current time is used as the target time. If there is a target time and the interval from the target time to the current time is greater than the preset duration, the current time is used as the new target time.

[0100] Furthermore, in one embodiment, the second early warning module 30 is further used for:

[0101] Setting the first accumulated value at the target time to zero;

[0102] At each moment within a preset time after the target moment, the first accumulated value of the previous moment is added to the product of the friction power of the current moment and the interval between adjacent moments to obtain the first accumulated value of the current moment, and the first accumulated value of the current moment is used as the accumulated friction power from the target moment to the current moment.

[0103] Furthermore, in one embodiment, the state determination module 10 is used to:

[0104] If the clutch is in a semi-clutch state, detecting whether the accumulated sliding friction work of this semi-clutch working condition is greater than a first preset threshold;

[0106] If the current gear position of the vehicle is not the 1st gear or the reverse gear, the first warning prompt is output;

[0107] If the current gear position of the vehicle is 1st gear or reverse gear, then detecting whether the duration of the current semi-clutch working condition is greater than a second preset threshold;

[0108] If the duration of the semi-linkage working condition is longer than the second preset threshold, a second warning prompt is output;

[0109] If the duration of the current semi-clutch working condition is less than or equal to the second preset threshold, detecting whether the clutch speed difference at the current moment is greater than the third preset threshold;

[0110] If the clutch speed difference at the current moment is greater than the third preset threshold, a third warning prompt is output.

[0111] Furthermore, in one embodiment, the step of determining whether the clutch is in a semi-clutch state comprises:

[0112] If the vehicle gear at the current moment is not neutral, the transmission input shaft speed at the current moment is greater than the fifth preset threshold, and the clutch speed difference at the current moment is greater than the sixth preset threshold, it is determined that the clutch is in a semi-clutch state at the current moment.
