Description

[0001] The present invention relates to the technical field of engine control, and in particular to a gearbox shifting method, device, vehicle and computer storage medium. Background Art

[0002] As a core component of automobiles, manual transmissions are still widely used in the existing vehicle market.

[0003] There may be many problems when the existing manual transmission is shifting gears. First, it is easy to have a jerking phenomenon when shifting gears. This is because the engine speed and the gear speed of the transmission gear are not synchronized in the low gear. Improper operation will cause the engine speed to not match the new gear, resulting in a large speed difference. At the same time, the torque of the low gear changes greatly. These factors work together to cause the vehicle to jerk, which not only affects the acceleration comfort, but also causes impact noise to the transmission system. Secondly, low-gear shifting will increase the wear of the synchronizer. Due to the low vehicle speed and the large range of engine speed changes, the synchronizer needs to work under a large speed difference. If the shifting operation is rough, it will further increase the burden on the synchronizer. The worn synchronizer will make shifting gears difficult, and even cause problems such as unsmooth gear shifting and gear knocking. Finally, low-gear shifting requires higher operation requirements from the driver. When there is a sense of frustration when shifting low gears, novice drivers are prone to nervousness and make operational errors. It takes rich experience and skills to accurately grasp the timing and method of low-gear shifting under different road conditions and driving conditions, otherwise it may bring safety hazards.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

"And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" may mean: A exists alone, A and B exist at the same time, and B exists alone.

Therefore, the technical features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0022] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] A specific embodiment of the present invention, as Figure 1 As shown, a gearbox shifting method is disclosed, comprising: S101, obtaining vehicle driving state information during vehicle driving; S102, when it is determined based on the vehicle driving state information that the vehicle enters a gear shift state, obtaining a gear shift fuel injection amount and a gear shift speed value of the vehicle engine at the moment of entering the gear shift state; S103, during the gear shifting process of the vehicle, maintaining the fuel injection amount of the vehicle engine at the gear shifting fuel injection amount, and maintaining the speed value of the vehicle engine at the gear shifting speed value, until the vehicle exits the gear shifting state.

[0024] In the embodiment of the present application, the gearbox shifting method provided is applicable to a manual gearbox, and is used to prevent the manual gearbox from having a sense of frustration when performing an upshift operation in a low gear. Specifically, during the driving of the vehicle, the vehicle driving state information is obtained, and the running state information is used to determine whether the vehicle enters a gear shifting state. Specifically, the vehicle driving state information includes the vehicle speed, the throttle opening, and the engine speed value. When the vehicle is judged to enter a gear shifting state based on the above vehicle driving state information, the gear shifting injection amount and the gear shifting speed value of the vehicle engine at the time of entering the gear shifting state are obtained, and during the vehicle gear shifting process, the vehicle engine is continuously fueled, and the fuel supply amount is the gear shifting injection amount, so as to maintain the speed of the vehicle engine at the gear shifting speed value until the vehicle exits the gear shifting state.

[0025] The gearbox shifting method provided by the present invention continuously obtains the driving state information of the vehicle, and determines whether the vehicle enters the gear shifting state according to the driving state information of the vehicle. When the vehicle enters the gear shifting state, the gear shifting fuel injection amount and the gear shifting speed value at the moment when the vehicle engine enters the gear shifting state are obtained, and during the entire gear shifting process of the vehicle, the fuel injection amount of the vehicle engine is maintained at the gear shifting fuel injection amount, and the engine speed is maintained at the gear shifting speed value until the vehicle exits the gear shifting state. The present invention can maintain the engine state at the state at the moment before the gear shifting when the vehicle shifts gears, and the gear shifting process is smoother without setbacks, thereby improving the safety of vehicle driving.

[0026] In a possible implementation manner of the present application, the judgment condition for the vehicle to enter the gear shift state is: From the first moment to the second moment, the vehicle speed continuously increases from the first speed value to the second speed value, and the vehicle engine speed continuously increases from the first speed value to the second speed value, and at the second moment, the throttle opening of the vehicle is 0.

[0027] In the embodiment of the present application, when determining whether the vehicle enters the gear shift state based on the vehicle driving state information, it is necessary to combine the vehicle driving state information in a continuous time period for judgment. Specifically, during the continuous time period from the first moment to the second moment, if it is detected that the vehicle speed is increasing continuously, such as the vehicle speed is increased from Increase to , and during this continuous period of time, the engine speed of the vehicle is constantly increasing, such as the engine speed from Increase to , and at the second moment, the throttle opening of the vehicle suddenly changes to 0, which means that the vehicle has been accelerating, and the driver releases the throttle before shifting gears, which means that the vehicle is about to enter the shift mode.

[0028] In another possible implementation, the vehicle driving state information further includes the clutch state of the vehicle, and the judgment condition for the vehicle entering the gear shift state further includes: From the first moment to the second moment, the vehicle speed continuously increases from the first speed value to the second speed value, the vehicle engine speed continuously increases from the first speed value to the second speed value, at the second moment the vehicle's throttle opening is 0 and the vehicle's clutch is closed.

[0029] In an embodiment of the present application, the vehicle driving status information also includes the vehicle's clutch status information, and the clutch status information includes clutch closing or clutch disconnection. When judging whether the vehicle enters a gear shifting state based on the vehicle driving status information, in addition to the conditions in the aforementioned embodiment, based on the actual operation of the driver driving the vehicle, it is also necessary to determine whether the vehicle's clutch is in a closed state. When the vehicle meets all the conditions of the previous embodiment and the vehicle's clutch is in a closed state, it is determined that the vehicle enters a gear shifting state.

[0030] The embodiment of the present application can accurately determine whether the vehicle enters the gear shift mode based on the specific operation of the driver driving the vehicle and combining various vehicle driving status information.

[0031] As a possible implementation of the present application, in this implementation, obtaining the shifting fuel injection amount and the shifting speed value of the vehicle engine at the moment of entering the shifting state includes: The second speed value is used as the gear-shift speed value, and the fuel injection amount of the engine when the speed value of the engine increases to the second speed value is used as the gear-shift fuel injection amount.

[0032] In the embodiment of the present application, after the vehicle enters the gear shifting state, in order to prevent the vehicle from stalling during the gear shifting, it is necessary to control the speed of the vehicle engine during the gear shifting process, and the engine speed control is achieved by controlling the engine fuel injection amount, therefore, it is necessary to control the engine fuel injection amount and speed during the gear shifting process. Specifically, the vehicle enters the gear shifting state at the second moment, at which time the speed of the vehicle engine is the second speed value, in order to prevent the vehicle from shaking, the speed of the vehicle engine during the gear shifting process can be maintained at the second speed value, and the second speed value can be used as the gear shifting speed value; and when the vehicle enters the gear shifting state at the second moment, the fuel injection amount of the vehicle engine is the fuel injection amount for the vehicle to maintain the second speed value, therefore the fuel injection amount at this time can be used as the gear shifting fuel injection amount.

[0033] The embodiment of the present application obtains the engine speed and fuel injection amount at the second moment when the vehicle enters the gear shift state, and determines them as the gear shift fuel injection amount and gear shift speed values, thereby providing reasonable standard values ​​for subsequent engine control.

[0034] As a possible implementation of the present application, in this implementation, the judgment condition for the vehicle to exit the gear shift state is: The vehicle's throttle opening is greater than 0 and / or the vehicle's clutch is disengaged.

[0035] In an embodiment of the present application, based on actual driving conditions, there are two judgment conditions for whether the vehicle exits the gear shift state: the vehicle throttle opening is greater than 0 and the vehicle's clutch is in a disconnected state. If at least one of the above two conditions is met, it means that the vehicle has exited the gear shift state.

[0036] Furthermore, the judgment condition for the vehicle to exit the gear shift state also includes maintaining the fuel injection amount of the vehicle engine at the gear shift fuel injection amount and maintaining the speed value of the vehicle engine at the gear shift speed value for a duration that reaches a preset first duration threshold.

[0037] In the embodiment of the present application, during the gear shifting process of the vehicle, the throttle opening will continue to be 0. During this time period, the fuel injection amount of the engine is controlled to be maintained at the gear shifting fuel injection amount determined in the above embodiment, and the engine speed is controlled to be the gear shifting speed value determined in the above embodiment, so as to ensure that the operating state of the engine during the gear shifting process is basically the same as the operating state at the moment before the gear shifting, thereby ensuring that the vehicle will not shake during the gear shifting process, thereby improving the driving experience. Furthermore, there is another situation of exiting the gear shifting state, that is, after the vehicle enters the gear shifting state, the fuel injection amount of the vehicle engine is maintained at the gear shifting fuel injection amount, and the speed value of the vehicle engine is maintained at the gear shifting speed value. When the maintenance time reaches the preset first time threshold (such as 2 seconds), under normal circumstances, the gear shifting should be completed at this time, but the driver did not step on the accelerator to accelerate. At this time, it can still be determined that the vehicle has exited the gear shifting state.

[0038] The gearbox shifting method provided in the embodiment of the present invention can improve the gear shifting efficiency, shorten the gear shifting time, prevent discontinuous gear shifting power, shorten the power response time of the whole vehicle, reduce the speed difference between the engine and the gearbox, make the gear shifting smoother, and prevent the feeling of frustration.
