Description

Technical Field

[0001] The present application relates to the field of computer technology, in particular to the field of automobile automatic transmission technology, and specifically to a gear control method, device, equipment and storage medium. Background Art

[0002] With the development of mechanical intelligence, automatic transmission technology is widely used in vehicle control. It prepares the next gear in advance and realizes gear switching to the next gear when the current gear is disengaged.

[0003] Currently, the common gear control method is to immediately prepare for the next gear upon engaging the current gear. If the vehicle operates in the current gear for an extended period, the preparation time for the next gear will also increase. However, prolonged preparation time for the next gear can increase wear on mechanical components, leading to torque loss, reduced fuel consumption, and other negative effects. Summary of the Invention

[0004] This application provides a gear control method, device, equipment, and storage medium to at least solve the technical problem of long gear preparation time in related technologies. The technical solution of this application is as follows:

[0005] According to a first aspect of the present application, a gear control method is provided, comprising: during operation in a current gear, when first operating data of a vehicle at a first moment satisfies a preset gear preparatory condition, executing a preparatory operation for a target gear. The target gear is any gear greater than or less than the current gear. When second operating data of the vehicle at a second moment satisfies a preset preparatory cancellation condition, canceling the preparatory operation for the target gear. The second moment is any moment after the preparatory operation for the target gear has been executed.

[0006] According to the above technical means, during the operation of the current gear, the present application only needs to perform the preparation operation for the target gear if the first operating data of the vehicle meets the gear preparation condition. Afterwards, if the vehicle operating data meets the cancellation preparation condition, the preparation operation for the target gear can be canceled. Compared with the general technology that requires a long time to prepare for the next target gear during the operation of the current gear, the present application can flexibly execute or cancel the preparation operation, effectively reducing the preparation time for the target gear, and thus can reduce the wear and tear of mechanical parts and other impacts caused by the preparation of the gear.

[0007] In one possible embodiment, the first operating data includes: a first variation parameter, a gear shift time of the vehicle, and a first vehicle speed; the first variation parameter is used to represent a speed change of the vehicle at a first moment; the first variation parameter includes a first acceleration of the vehicle at the first moment; and the first vehicle speed is the actual vehicle speed of the vehicle at the first moment. When the first operating data of the vehicle at the first moment meets a preset gear preparation condition, a method for performing a preparatory operation for a target gear includes: when the first variation parameter is less than a preset minimum value or the first variation parameter is greater than a preset maximum value, determining the product of the first acceleration and the gear shift time as a first vehicle speed offset after the gear shift occurs at the first moment; determining the sum of the first vehicle speed offset and the first vehicle speed as a first offset vehicle speed after the gear shift occurs at the first moment; performing the preparatory operation for the target gear when the first offset vehicle speed is greater than a preset upshift speed or less than a preset downshift speed; when the first offset vehicle speed is greater than the preset upshift speed, the target gear is greater than the current gear of the vehicle; and when the first offset vehicle speed is less than the preset downshift speed, the target gear is less than the current gear.

[0008] Based on the above technical means, the present application can determine a first offset vehicle speed after the vehicle shifts gears at the first moment based on the vehicle's speed change at the first moment, the gear shift duration, and the actual vehicle speed. Furthermore, based on the first offset vehicle speed, it can determine whether a preparatory operation is required. Therefore, the present application provides a method for determining whether gear preparation is required based on vehicle operating data, which can accurately determine the vehicle's gear shift requirements, flexibly execute preparatory operations, and effectively reduce the preparation time for the target gear.

[0009] In one possible embodiment, the second operating data includes: the second acceleration of the vehicle at the second moment, the gear switching time and the second vehicle speed; the second vehicle speed is the actual vehicle speed of the vehicle at the second moment; when the second operating data of the vehicle at the second moment meets the preset cancellation preparation conditions, the preparatory operation of the target gear is canceled, including: the product of the second acceleration and the gear switching time is determined as the second vehicle speed offset after the gear switch occurs at the second moment; the sum of the second vehicle speed offset and the second vehicle speed is determined as the second offset speed of the vehicle after the gear switch occurs at the second moment; when the second offset speed is less than the preset minimum speed for upshifting, or greater than the preset maximum speed for downshifting, the preparatory operation of the target gear is canceled.

[0010] According to the above technical means, the present application can determine the second offset vehicle speed after the vehicle shifts gears at the second moment based on the vehicle's second acceleration, gear shift duration, and actual vehicle speed at the second moment, and then determine whether to cancel the previously executed preparatory operation based on the second offset vehicle speed. Therefore, the present application provides a method for determining whether to cancel the execution of gear preparation based on the vehicle's operating data after the vehicle executes gear preparation. This method can accurately determine the vehicle's gear shift requirements, flexibly cancel the execution of preparatory operations, and effectively reduce the preparation time for the target gear.

[0011] In a possible embodiment, the above-mentioned gear control method also includes: multiplying the time it takes for the vehicle to switch between any two gears by a preset time coefficient to determine the gear switching time; the gear switching time is greater than the time it takes for the vehicle to switch between any two gears.

[0012] According to the above technical means, since the time taken to switch gears in this application is greater than the time taken to switch between any two gears of the vehicle, the gear control method of this application can be applied to the situation where the vehicle switches between any two gears, thereby improving the accuracy of the offset speed of the vehicle after the gear switch occurs.

[0013] In a possible implementation manner, the first change parameter further includes: a change rate of the vehicle throttle opening.

[0014] According to the above technical means, since the rate of change of the vehicle's throttle opening is related to the force with which the user depresses the accelerator pedal, it can reflect the user's willingness to adjust the vehicle speed. Therefore, when determining whether to perform the preparatory operation for the target gear, the present application adds the rate of change of the vehicle's throttle opening to the first change parameter, which can effectively improve the accuracy of determining the vehicle's speed change.

[0015] In a possible implementation, the gear control method further includes: when the second operating data satisfies a preset gear switching condition, executing a switching operation from the current gear to the target gear.

[0016] According to the above technical means, after performing the preparatory operation, the present application can also determine whether it is necessary to perform a gear switching operation based on the vehicle's operating data at the second moment, thereby realizing the vehicle's automatic speed shifting function.

[0018] According to the above technical means, the present application can determine whether a gear shift operation needs to be performed based on the actual speed of the vehicle at the second moment.

[0021] In one possible implementation, the second operating data includes: a second acceleration of the vehicle at a second moment, a gear switching time, and a second vehicle speed; the second vehicle speed is the actual vehicle speed of the vehicle at the second moment; and a cancellation preparatory unit is specifically used to: determine the product of the second acceleration and the gear switching time as a second vehicle speed offset after the vehicle switches gears at the second moment; determine the sum of the second vehicle speed offset and the second vehicle speed as a second offset vehicle speed after the vehicle switches gears at the second moment; and cancel the preparatory operation of the target gear when the second offset vehicle speed is less than a preset minimum speed for upshifting, or greater than a preset maximum speed for downshifting.

[0022] In one possible embodiment, the gear control device further includes: a determination unit; a determination unit, configured to determine the gear switching time as the product of the time taken for the vehicle to switch between any two gears and a preset time coefficient; the gear switching time is greater than the time taken for the vehicle to switch between any two gears.

[0029] Therefore, the above technical features of this application have the following beneficial effects:

[0030] (1) In the present application, during the operation of the current gear, if the first operating data of the vehicle satisfies the gear preparation condition, the preparation operation for the target gear needs to be executed. Thereafter, if the operating data of the vehicle satisfies the cancellation condition, the preparation operation for the target gear can be canceled. Compared with the general technology that requires a long time to prepare for the next target gear during the operation of the current gear, the present application can flexibly execute or cancel the preparation operation, effectively reducing the preparation time for the target gear, thereby reducing the wear of mechanical parts and other effects caused by the preparation of the gear.

[0031] (2) The present application can determine the first offset vehicle speed after the vehicle shifts gears at the first moment based on the vehicle's speed change at the first moment, the gear shifting time, and the actual vehicle speed, and then determine whether a preparatory operation is required based on the first offset vehicle speed.

[0032] (3) The present application can determine the second offset vehicle speed after the vehicle shifts gears at the second moment based on the second acceleration of the vehicle at the second moment, the gear shifting time, and the actual vehicle speed, and then determine whether it is necessary to cancel the preparatory operation that was previously executed based on the second offset vehicle speed. Therefore, the present application provides a method for determining whether it is necessary to cancel the gear preparation based on the vehicle's operating data after the vehicle performs gear preparation. This method can accurately determine the vehicle's gear shifting requirements, flexibly cancel the preparatory operation, and effectively reduce the preparation time for the target gear.

[0033] (4) Since the gear switching time in the present application is greater than the time the vehicle takes to switch between any two gears, the gear control method of the present application can be applied to the situation where the vehicle switches between any two gears, thereby improving the accuracy of the offset speed of the vehicle after the gear switch occurs.

[0034] (5) Because the rate of change of the vehicle's throttle opening is related to the force with which the user steps on the accelerator pedal, it can reflect the user's willingness to adjust the vehicle's speed. Therefore, when determining whether to perform the preparatory operation for the target gear, the present application adds the rate of change of the vehicle's throttle opening to the first change parameter, which can effectively improve the accuracy of determining the vehicle's speed change.

[0035] (6) After executing the preparatory operation, the present application can also determine whether a gear shift operation needs to be executed based on the vehicle's operating data at the second moment, thereby realizing the vehicle's automatic speed shifting function.

[0048] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0050] With the development of mechanical intelligence, automatic transmission technology is widely used in vehicle control. It prepares the next gear in advance and realizes gear switching to the next gear when the current gear is disengaged.

[0051] Automatic transmission technologies include single-clutch and multi-clutch transmissions. Dual-clutch transmissions are the primary form of automatic transmission technology due to their simple structure, high efficiency, and lack of power interruption. A dual-clutch transmission connects to two input shafts via two clutches, which control the even and odd gears, respectively.

[0052] Currently, the common gear control method is to immediately prepare for the next gear upon engaging the current gear. If the vehicle operates in the current gear for an extended period, the preparation time for the next gear will also increase. However, prolonged preparation time for the next gear can increase wear on mechanical components, leading to torque loss, reduced fuel consumption, and other negative effects.

[0053] To solve the above technical problems, the present application can execute the preparation operation for the target gear only if the first operating data of the vehicle meets the gear preparation condition during the operation of the current gear. Afterwards, if the operating data of the vehicle meets the cancellation condition, the preparation operation for the target gear can be canceled. Compared with the general technology that requires a long time to prepare for the next target gear during the operation of the current gear, the present application can realize the flexible execution or cancellation of the preparation operation, effectively reducing the preparation time for the target gear, thereby reducing the wear and tear of mechanical parts and other effects caused by the preparation of the gear.

[0054] For ease of understanding, the gear control method provided in this application is described in detail below with reference to the accompanying drawings.

[0055] Figure 1 FIG. 1 is a flow chart showing a method for controlling a gear position according to an exemplary embodiment. Figure 1 As shown, the gear control method includes the following steps:

[0056] S101. During operation in a current gear, when first operating data of a vehicle at a first moment satisfies a preset gear preparation condition, a gear control device executes a preparation operation for a target gear.

[0057] Optionally, the first operating data may include: a first change parameter, a gear switching time, and a first vehicle speed.

[0058] The first variation parameter is used to represent the change in the speed of the vehicle at the first moment. Optionally, the first variation parameter may include: a first acceleration of the vehicle at the first moment and a rate of change of the throttle opening of the vehicle.

[0059] It should be noted that the rate of change of the vehicle's throttle opening is related to the force with which the user depresses the accelerator pedal, and thus can reflect the user's willingness to adjust the vehicle's speed. Therefore, when determining whether to execute the preparatory operation for the target gear, this application adds the rate of change of the vehicle's throttle opening to the first change parameter, effectively improving the accuracy of determining the vehicle's speed change.

[0060] In one achievable method, in order to make the gear control method of the present application applicable to the situation where the vehicle switches between any two gears, the gear switching time needs to cover the time consumed by the vehicle switching between any two gears. Therefore, the method for determining the gear switching time may include: S1.

[0061] S1. The gear control device determines the product of the vehicle's switching time between any two gears and a preset time coefficient as the gear switching time.

[0062] Specifically, the formula for determining the gear shifting time may include:

[0063] T = t × m;

[0064] Where t is the time it takes for the vehicle to shift from any gear to any other gear. For example, in a dual-clutch automatic transmission, the time it takes for the same shift fork to control different gears to shift, or the time it takes for different shift forks to control different gears to shift. m is a preset time coefficient related to the vehicle's current gear, and m>1.

[0065] It is easy to understand that since m>1, T>t must be satisfied.

[0066] For example, it is preset that it takes 1 second to switch from 5th gear to 7th gear, 2 seconds to switch from 5th gear to 6th gear, and the longest time taken to switch between any two gears of the vehicle is 3 seconds. To ensure the switching between any two gears, 3.5 seconds can be determined as the switching time between any two gears.

[0067] The first vehicle speed is used to represent the actual vehicle speed of the vehicle at the first moment.

[0068] The target gear is a preselected gear, and the target gear can be any gear that is greater than or less than the current gear.

[0069] Optionally, when the vehicle's speed variation is outside a preset stable speed variation range, indicating that the vehicle's speed is about to significantly change, the gear control device may determine whether to perform a preparatory operation for the target gear. Therefore, the gear preparatory condition may be used to define the vehicle's speed variation, for example, if the first variation parameter is greater than a preset maximum value or less than a preset minimum value.

[0070] Exemplarily, in the preset gear preparation conditions, the preset maximum value of the first acceleration is 10 meters per square second, the preset minimum value is 0.5 meters per square second, the preset maximum value of the change rate of the vehicle throttle opening is 4 centimeters per second, and the preset minimum value is 0.1 centimeters per second.

[0071] When vehicle A is operating in fifth gear, its speed is 72 kilometers per hour. Vehicle A maintains a constant speed, and the corresponding rate of change of vehicle A's throttle opening and the first acceleration are both 0. Because the rate of change of vehicle A's throttle opening of 0 centimeters per second is less than 0.1 centimeters per second, and the first acceleration of 0 meters per square second is less than the preset minimum value of 0.5 meters per square second, the gear control device pre-engages the vehicle in neutral.

[0072] When vehicle B is operating in 5th gear, its speed is 72 kilometers per hour. As vehicle B accelerates, the corresponding rate of change of vehicle B's throttle position is 1 centimeter per second and the first acceleration is 5 meters per second squared. Because vehicle B's throttle position change rate of 1 centimeter per second is greater than the preset minimum value of 0.1 centimeter per second and less than the preset maximum value of 4 centimeter per second, and the first acceleration of 5 meters per second squared is greater than the preset minimum value of 0.5 meters per second squared and less than the preset maximum value of 10 meters per second squared, the gear preparation conditions are met. At this time, vehicle B's speed is changing rapidly, and the gear control device performs the preparation operation for 6th gear.

[0073] S102: When the second operating data of the vehicle at the second moment satisfies a preset cancellation preparation condition, the gear control device cancels the preparatory operation of the target gear.

[0074] The second moment is any moment after the preparatory operation for the target gear is performed.

[0075] Optionally, the second operating data may include: a second acceleration of the vehicle at a second moment, a gear shifting time, and a second vehicle speed. The second vehicle speed is used to represent an actual vehicle speed of the vehicle at the second moment.

[0076] Alternatively, when the estimated actual vehicle speed after the gear shift at the second moment, i.e., the second offset speed, is within the speed range of the current gear, indicating that the current gear can meet the vehicle's speed change requirement, the gear control device may determine whether to cancel the preparatory operation for the target gear. Therefore, the cancellation condition may be defined by the second offset speed, for example, if the second offset speed is greater than a preset maximum downshift speed or less than a preset minimum upshift speed.

[0077] For example, when vehicle C is running in 5th gear, the preset minimum vehicle speed for upshifting is 100 kilometers per hour, and the preset maximum vehicle speed for downshifting is 60 kilometers per hour.

[0078] After executing the preparatory operation for the 6th gear, the gear control device determines that the second offset speed of vehicle C is 75 kilometers per hour, which is less than the preset minimum speed for upshifting. At this time, the gear control device cancels the preparatory operation for vehicle C in the 6th gear.

[0079] The technical solution provided above brings at least the following beneficial effects: As can be seen from S101-S102, during the operation of the current gear, the gear control device only needs to perform the preparatory operation for the target gear if the vehicle's first operating data meets the gear preparation condition. Thereafter, if the vehicle's operating data meets the cancellation condition, the gear control device can cancel the preparatory operation for the target gear. Compared to the general technology that requires a long time to prepare for the next target gear during the operation of the current gear, the present application can flexibly execute or cancel the preparatory operation, effectively reducing the preparation time for the target gear, thereby reducing the wear and tear of mechanical parts and other impacts caused by the preparatory gear.

[0080] In an optional embodiment, the present application specifically provides a method for determining a preparatory operation for executing a target gear according to first operating data. Figure 1 ,like Figure 2 As shown, in S101, during the operation of the current gear, when the first operating data of the vehicle at the first moment meets the preset gear preparation condition, the method in which the gear control device performs the preparation operation for the target gear specifically includes:

[0081] S201. When the first change parameter is less than a preset minimum value, or the first change parameter is greater than a preset maximum value, the gear control device determines the product of the first acceleration and the gear switching time as the first vehicle speed offset after the gear switching occurs at the first moment.

[0082] It is easy to understand that the first acceleration of the vehicle at the first moment represents the speed change trend of the vehicle at the first moment, and the gear switching time can represent the time it takes for the gear control device to switch to the target gear. The product of the first acceleration and the gear switching time can represent the speed change of the vehicle after the gear switch occurs at the first moment, that is, the first vehicle speed offset. Therefore, the formula for determining the first vehicle speed offset may include:

[0083] V offset =a×T;

[0084] Where a is the first acceleration of the vehicle at the first moment, V offset is the first speed offset of the vehicle at the first moment.

[0085] like Figure 3 As shown, when the vehicle accelerates, the direction of the first acceleration is positive, and the direction of the corresponding first vehicle speed offset is also positive.

[0086] like Figure 4 As shown, when the vehicle is decelerating, the direction of the first acceleration is negative, and the direction of the corresponding first vehicle speed offset is also negative.

[0087] S202 : The gear control device determines the sum of the first vehicle speed offset and the first vehicle speed as the first offset vehicle speed after the gear switch occurs at the first moment.

[0088] It is easy to understand that the first vehicle speed is used to represent the actual vehicle speed at the first moment, and the first vehicle speed offset is used to represent the change in vehicle speed after the gear shift occurs at the first moment. Therefore, the estimated value of the actual vehicle speed after the gear shift occurs at the first moment, that is, the first offset vehicle speed, can be expressed as the sum of the first vehicle speed and the first vehicle speed offset. Therefore, the formula for determining the offset vehicle speed can be:

[0089] V new =V current +V offset

[0090] Among them, V new is the first offset speed, V current is the actual speed of the vehicle at the first moment, V offset is the first vehicle speed offset of the vehicle at the first moment.

[0091] like Figure 3 As shown, when the vehicle accelerates, the direction of the first vehicle speed offset is positive, and the first offset vehicle speed is greater than the actual vehicle speed.

[0092] like Figure 4 As shown, when the vehicle is decelerating, the direction of the first vehicle speed offset is negative, and the first offset vehicle speed is less than the actual vehicle speed.

[0093] S203: When the first offset vehicle speed is greater than the preset upshift vehicle speed or less than the preset downshift vehicle speed, the gear control device performs a preparatory operation for the target gear.

[0094] It is easy to understand that when the first offset vehicle speed is greater than the preset upshift speed, the target gear is greater than the vehicle's current gear. In actual applications, vehicles generally cannot shift across gears, and the target gear may be one gear higher than the current gear. When the first offset vehicle speed is less than the preset downshift speed, the target gear is less than the current gear. In actual applications, the target gear may be one gear lower than the current gear.

[0095] For example, the preset first speed of vehicle B when running in 4th gear is 40 kilometers per hour, the first acceleration is 5 meters per square second, the time taken to switch between any two gears is 1.25 seconds, the time coefficient is 1.6, the preset upshift speed is 60 kilometers per hour, and the preset downshift speed is 35 kilometers per hour.

[0096] The shift from 4th to 5th gear takes 2 seconds, the first speed offset is 10 meters per second (36 kilometers per hour), and the first offset vehicle speed is 76 kilometers per hour. Because the first offset vehicle speed of 76 kilometers per hour is greater than the preset upshift speed of 60 kilometers per hour, the gear control device performs a preparatory operation for 5th gear.

[0097] The technical solution provided above provides at least the following beneficial effects: As can be seen from S201-S203, the gear control device can determine a first offset vehicle speed after the vehicle shifts at the first moment based on the vehicle's speed change at the first moment, the gear shift duration, and the actual vehicle speed, and further determine whether a preparatory operation is required based on the first offset vehicle speed. Therefore, the present application provides a method for determining whether gear preparatory operation is required based on vehicle operating data, which can accurately determine the vehicle's gear shift requirements, flexibly execute preparatory operations, and effectively reduce the preparation time for the target gear.

[0098] In an optional embodiment, the present application specifically provides a method for canceling the preparatory operation of the target gear according to the second operating data of the vehicle. Figure 1 ,like Figure 2 As shown, in S102, after performing the preparatory operation, when the second operating data of the vehicle at the second moment meets the preset cancellation preparatory condition, the method for canceling the preparatory operation of the target gear specifically includes:

[0099] S204: The gear control device determines the product of the second acceleration and the gear switching time as a second vehicle speed offset after the gear switching occurs at the second moment.

[0100] The method for determining the second vehicle speed offset may refer to the description of determining the first vehicle speed offset in S301 , and will not be repeated here.

[0101] S205 : The gear control device determines the sum of the second vehicle speed offset and the second vehicle speed as the second offset vehicle speed after the gear switch occurs at the second moment.

[0102] The method for determining the second offset vehicle speed may refer to the description of determining the first offset vehicle speed in S302 , and will not be repeated here.

[0103] S206: When the second offset vehicle speed is less than the preset minimum vehicle speed for upshifting, or greater than the preset maximum vehicle speed for downshifting, the gear control device cancels the preparatory operation for the target gear.

[0104] like Figure 3 、 Figure 4 As shown, the maximum downshift speed is used to indicate the maximum value of the transition speed when the current gear is switched to a target gear that is smaller than the current gear.

[0105] The preset downshift speed is used to represent the speed threshold between the current gear and the target gear that is smaller than the current gear.

[0106] The minimum vehicle speed for upshifting is used to indicate the minimum transition vehicle speed when the current gear is switched to a target gear that is greater than the current gear.

[0107] The preset upshift speed is used to represent the speed threshold between the current gear and the target gear that is greater than the current gear.

[0108] The neutral gear area is used to indicate the value range of the second offset vehicle speed when the running speed of the current gear can meet the speed change requirement of the vehicle after the vehicle performs the preparatory operation.

[0109] The downshift range indicates the range of values ​​for the first offset speed when the vehicle's pre-shift position is neutral, that is, when no pre-shift operation is performed and the vehicle's speed in the current gear is greater than the vehicle's speed after the downshift. It also indicates the range of values ​​for the second speed when the vehicle's speed in the current gear is greater than the vehicle's actual speed after the pre-shift operation is performed.

[0110] The upshift range indicates the range of first offset vehicle speeds when the vehicle's pre-shift position is neutral, that is, when no pre-shift operation is performed and the vehicle's speed in the current gear is lower than the vehicle's speed after the upshift. It also indicates the range of second vehicle speeds when the vehicle's speed in the current gear is lower than the vehicle's actual speed after the pre-shift operation is performed.

[0111] For example, when vehicle C is running in 4th gear, the second vehicle speed is preset to be 50 kilometers per hour, the second acceleration is 2.5 meters per square second, the switching time between any two gears is 1.25 seconds, the time coefficient is 1.6, the gear switching time from 4th gear to 5th gear is 2 seconds, the second speed offset is 18 kilometers per hour, the second offset speed is 68 kilometers per hour, the preset minimum speed for upshifting is 60 kilometers per hour, and the preset speed for downshifting is 40 kilometers per hour.

[0112] Since the second offset vehicle speed of 68 kilometers per hour is greater than the minimum vehicle speed for upshifting of 60 kilometers per hour, the gear control device does not cancel the preparatory operation.

[0113] The technical solution provided above provides at least the following beneficial effects: As can be seen from S204-S206, the gear control device of this application can determine a second offset vehicle speed after the vehicle shifts gears at the second moment based on the second acceleration of the vehicle at the second moment, the gear shift duration, and the actual vehicle speed, and further determine whether to cancel the previously executed preparatory operation based on the second offset vehicle speed. Therefore, this application provides a method for determining whether to cancel the gear preparation execution based on the vehicle's operating data after the vehicle executes the gear preparation. This method can accurately determine the vehicle's gear shift requirements, flexibly cancel the preparatory operation, and effectively reduce the preparation time for the target gear.

[0114] In an optional embodiment, the present application also provides a method for determining gear switching. Figure 2 ,like Figure 5 As shown, the gear control method further includes:

[0115] S501: When the second operating data meets a preset gear switching condition, the gear control device performs a switching operation from the current gear to the target gear.

[0116] Alternatively, after preparatory operations for the target gear have been performed, if the vehicle's actual speed is not within the operating speed range of the current gear, it indicates that the vehicle needs to switch operating gears. Therefore, the gear switching condition can be used to limit the vehicle's actual speed, for example, the second vehicle speed is greater than a preset upshift speed.

[0117] In one achievable manner, in S501 , when the second operating data satisfies a preset gear switching condition, the method in which the gear control device executes a switching operation from the current gear to the target gear specifically includes: S2 .

[0118] S2. When the second vehicle speed is greater than a preset upshift speed or less than a preset downshift speed, the gear control device performs a shift operation from the current gear to the target gear.

[0119] According to the actual speed of the vehicle at the second moment, it is determined whether the gear switching operation needs to be executed, so that the gear shifting requirement of the vehicle can be accurately judged and the automatic speed shifting function of the vehicle can be realized.

[0120] For example, when vehicle D is running in 4th gear, the preset upshift speed is 60 kilometers per hour, the preset downshift speed is 40 kilometers per hour, and after performing the preparatory operation from 4th gear to 5th gear, the second speed of vehicle D is 65 kilometers per hour.

[0121] Since the second vehicle speed of the vehicle D is 65 kilometers per hour, which is greater than the preset upshift speed of 40 kilometers per hour, the gear control device performs a shift operation from 4th gear to 5th gear.

[0122] The technical solutions provided by the above embodiments provide at least the following beneficial effects: Because the gear shifting time in this application is longer than the time it takes for a vehicle to switch between any two gears, the gear control method of this application is applicable to vehicle switching between any two gears, thereby improving the accuracy of the offset vehicle speed after a gear shift.

[0123] The following combination Figure 6 , the gear control method in this application is described. Figure 6 As shown, the gear control method specifically includes:

[0142] S611: The gear control device cancels the preparatory operation for executing the target gear.

[0143] After executing S611 , the gear control device returns to executing S601 .
