Although a flowchart depicts operations (or steps) as a sequential process, many of the operations (or steps) can be performed in parallel, concurrently, or at the same time.

The technical scheme of the application obtains, stores, uses and processes the data and the like all conform to the relevant regulations of national laws and regulations.
Fig. 1 is a flowchart of an engine speed control method according to an embodiment of the present application, where the embodiment is applicable to a case of controlling an engine speed during a gear shift, the method according to the embodiment may be performed by an engine speed control device, and the device may be implemented in hardware and/or software. The device can be configured in a server for engine speed control. The method specifically comprises the following steps:
s110, acquiring vehicle running information of the target vehicle, and determining that the target vehicle is in a gear shifting state.
The vehicle running information may refer to state information of the target vehicle during running. The vehicle travel information includes, but is not limited to, a current travel speed, a current clutch on-off state, a last time gear state, and a current neutral gear state. And determining the running state of the target vehicle according to the vehicle running information of the target vehicle. For example, if the current travel speed of the target vehicle is equal to zero, it is indicative that the target vehicle is in a stopped state.
As an alternative, but not limiting implementation manner, the step of obtaining the vehicle running information of the target vehicle and determining that the target vehicle is in a gear shifting state includes, but is not limited to, steps A1-A2:
step A1: and determining that the target vehicle is in a running state according to the current running speed and the current gear state of the target vehicle.
The method comprises the steps of acquiring vehicle running information of a target vehicle, and determining that the target vehicle is in a running state if the current running speed of the target vehicle is greater than zero and the current gear of the target vehicle is in a non-neutral state. For example, if the current running speed of the target vehicle is 30km/h and the current gear is in 2 gear, the target vehicle is indicated to be in a forward running state; and if the current running speed of the target vehicle is 5km/h and the current gear is located at the reverse gear, indicating that the target vehicle is in a reverse running state.
Step A2: and when the target vehicle is in a running state, determining that the target vehicle is in a gear shifting state according to the current neutral gear state and the current clutch switch state of the target vehicle.
When the target vehicle is in a driving state, whether the target vehicle is in a gear shifting state or not can be determined according to the neutral gear state and the clutch on-state. For example, if it is detected that the target vehicle is currently in a neutral state and the current clutch switch is open, it is indicative that the target vehicle is in a shift state at the current time. The clutch switch being turned off may mean that the driver depresses the clutch to disconnect the engine from the transmission.
A clutch is a component that cuts off or transmits power between an engine and an automobile transmission system. The control clutch, depressing or releasing the clutch, can temporarily disengage or progressively engage the engine with the driveline to cut off or transfer power output by the engine to the driveline. For a manual gear target vehicle, when the gear of the target vehicle is shifted, a neutral gear is needed to be shifted, a clutch is stepped on to separate the engine from the transmission, and after the required gear is determined, the clutch is released to combine the engine with the transmission, so that gear shifting is completed.
S120, predicting the target idle speed of the target vehicle according to the current running speed of the target vehicle and the gear state at the last moment.
During shifting, when a driver steps on a clutch, the engine is separated from the transmission, and power between the engine and the transmission is disconnected; because the transmission is coupled to the drive axle, the wheels of the vehicle will drive the gears within the transmission at high speeds through the driveline. For novice driving and gear shifting, as the accelerator pedal is released during gear shifting, if the gear shifting process is slower, the clutch is released for too long, and the engine speed can return to a lower idle speed, such as 700r/min; at this time, the engine and the transmission are required to be synchronized in the process of re-engaging gears and combining the clutch, if the speed difference is large, the gear engaging impact easily occurs in the process of synchronizing the rotational speeds, and the target vehicle is prevented from being flameout due to the sense of a bump during gear engaging. Therefore, the idle speed of the engine after the clutch is released in the driving process needs to be increased, and the large speed difference between the engine and the clutch is avoided.
In the embodiment of the application, the target idle speed of the engine of the target vehicle is predicted through the current running speed of the target vehicle and the speed ratio corresponding to the last gear, so that the speed difference between the speed of the engine and the speed of the speed changer is smaller.
As an optional but non-limiting implementation manner, the predicting the target idle speed of the target vehicle according to the current running speed of the target vehicle and the last time gear state includes but is not limited to steps B1-B2:
step B1: determining a speed ratio of a transmission of the target vehicle according to a gear state of the target vehicle at the moment; wherein different gear positions correspond to different transmission speed ratios.
The last gear state in the embodiment of the present application may refer to a state of a last gear, and may also be referred to as a gear state before gear shifting. For example, when shifting gears, the 3 rd gear is shifted to the 4 th gear state, and the 3 rd gear state is the last gear state in the application.
The speed ratio may refer to a ratio of the number of teeth of the driven gear to the number of teeth of the driving gear, and when a relationship between the number of teeth of the driven gear and the number of teeth of the driving gear is changed, the speed ratio is changed, and under the condition that the engine speed is unchanged, a change in the rotation speed of the output shaft, that is, a change in the rotation speed of the wheels, is affected. If the input shaft is provided with a plurality of gears with different numbers of teeth and the corresponding gears with different numbers of teeth on the output shaft are meshed, a group of step-variable speed variators with different speed ratios can be obtained, namely, different gear positions on the target vehicle correspond to different speed ratios. For example, a speed ratio of 2 gear may refer to 5.24,3 gear and may be 3.76. The gear ratios of different vehicles are different, and the embodiment of the application is not particularly limited.
Step B2: and determining the target idle speed of the target vehicle engine according to the current running speed of the target vehicle and the speed ratio of the transmission.
And predicting the target idle speed of the engine of the target vehicle according to the current running speed of the target vehicle and the speed ratio corresponding to the last gear. The target idle speed may refer to a speed that is less different from the transmission speed. For example, the rotational speed of the transmission at the previous gear is 1500r/min, and the rotational speed of the transmission varies within 1300 to 1800 revolutions when the target vehicle changes gear; if the clutch is released for too long, the rotating speed of the engine can be reduced to 700r/min, and the speed difference between the engine and the transmission is large, so that the normal gear shifting of the target vehicle can be influenced. If the rotation speed of the target vehicle engine is about 1000r/min, the speed difference between the engine and the transmission is reduced, and the gear shifting comfort is improved.
The target idle speed is predicted through the speed ratio corresponding to the last gear and the current running speed, so that the target idle speed of the engine can be controlled within a preset difference range with the speed of the last gear speed changer when the target idle speed of the engine is predicted. For example, the speed is increased during gear shifting, the current running speed is 60km/h, the speed ratio of the transmission in the last gear 3 is 3.76, the target idle speed obtained through the current running speed and the speed ratio corresponding to the last gear is 2168r/min, and the speed of the transmission is about 3000r/min when the current running speed is 60 km/h. If the clutch is released for a long time, the rotating speed of the engine is reduced to 700r/min, the rotating speed of the transmission is about 3000r/min, and the phenomenon of abrupt control or flameout can occur in the gear shifting and shifting process; in the application, the rotating speed of the engine is increased to 2168r/min, so that the speed difference between the engine and the transmission is reduced, the probability of occurrence of the phenomenon of jerk or flameout is reduced, and the gear shifting comfort is improved.
And S130, controlling the engine speed of the target vehicle according to the target idle speed.
The rotation speed of the engine of the target vehicle is displayed by an instrument on the target vehicle, and a specific rotation speed value cannot be accurately obtained when the rotation speed of the engine is controlled. For example, the target idle speed is 2168r/min, and when the engine speed is controlled, the engine speed is not accurately controlled to be 2168r/min, and the engine speed can be controlled to be increased to about 2000 revolutions by the accelerator pedal.
As an alternative but non-limiting implementation, the engine speed of the target vehicle is controlled according to the target idle speed, including but not limited to steps C1-C2:
step C1: and determining a preset rotating speed range of the target vehicle engine according to the target idle rotating speed of the target vehicle engine.
Step C2: the rotating speed of the target vehicle engine is controlled to be increased to be within a preset rotating speed range through an accelerator pedal; wherein the preset rotational speed range includes a target idle rotational speed.
And determining a preset rotating speed range of the target engine according to the target idle rotating speed. The preset rotational speed range includes a target idle rotational speed. For example, the target idle speed is 2000r/min, and the preset speed range may be plus or minus 80% of the target idle speed, that is, the preset speed range may be between 1600r/min and 2400 r/min. The rotating speed of the target engine is controlled by the accelerator pedal to be increased to be within a preset Fan Zhuaisu range, so that the rotating speed difference between the rotating speed of the engine and the rotating speed of the transmission is reduced, and the gear shifting comfort is improved.
As an alternative, but not limiting implementation manner, the step of controlling the rotation speed of the target vehicle engine by the accelerator pedal to rise to the preset rotation speed range includes, but is not limited to, steps D1-D2:
step D1: after the rotational speed of the target vehicle engine is raised to within the preset rotational speed range, it is determined whether the target vehicle has completed the shift operation.
Step D1: if the target vehicle does not complete the gear shifting operation and the neutral gear state is continuously neutral gear, the rotating speed of the engine of the target vehicle is reduced to the original idle rotating speed; the original idle speed is used for representing the speed of the target vehicle when the target vehicle is idling in a neutral state.
Wherein, referring to fig. 2, after the rotation speed of the target vehicle engine is raised to be within the preset rotation speed range, it is determined whether the target vehicle completes the shift operation. If the gear shifting is completed, continuing to run according to the gear after the gear shifting; if gear shifting is not completed and the gear is kept in a neutral state, judging that the target vehicle is in an idle sliding state; in a long-time coasting state, the rotational speed of the target vehicle engine will be reduced from the target idle rotational speed to which it was raised to the idle rotational speed at which neutral coasting was performed.
In an alternative aspect of the embodiment of the present application, if the gear shifting operation is not completed within a certain period of time after the idle speed is lifted, the speed of the target vehicle engine still drops from the lifted target idle speed to the idle speed when the idle speed is in neutral gear, and the target vehicle runs at the original idle speed.
As an alternative but non-limiting implementation, the target vehicle engine speed is reduced to the original idle speed, including but not limited to steps E1-E2:
step E1: after the rotation speed of the target vehicle engine is reduced to the original idle rotation speed, whether the opening degree of the accelerator pedal is larger than zero or not is judged.
Step E2: if the opening of the accelerator pedal is larger than zero and the gear is in a non-neutral state, the target vehicle runs in an acceleration mode; wherein an accelerator pedal opening greater than zero indicates that the target vehicle is accelerating.
After the rotation speed of the target vehicle engine is reduced to the original idle rotation speed, determining whether a driver gives an acceleration instruction or not; the acceleration instruction is characterized by whether the opening of the accelerator pedal is larger than zero; if the accelerator pedal is greater than zero, it is indicative that the driver is accelerating. If the driver is accelerating and the gear is in a non-neutral state, the target vehicle runs in an acceleration mode and accelerates to a running speed corresponding to the gear state according to the gear state.
The embodiment of the application provides an engine speed control method, which is used for determining that a target vehicle is in a gear shifting state by acquiring vehicle running information of the target vehicle; the vehicle running information comprises a current running speed, a current clutch switch state, a last-time gear state and a current neutral gear state; predicting the target idle speed of the target vehicle according to the current running speed of the target vehicle and the gear state at the last moment; and controlling the engine speed of the target vehicle according to the target idle speed. By adopting the technical scheme of the embodiment of the application, the target idle speed of the engine of the target vehicle is predicted according to the current running speed of the target vehicle and the speed ratio of the last gear, and the engine speed is increased to the target idle speed, so that the speed difference between the engine speed and the speed of the transmission is reduced, the gear shifting comfort is improved, the gear shifting impact is relieved, and the gear shifting frustration and flameout phenomenon are avoided.
