[0002] Nowadays, more and more people are choosing automatic transmissions when purchasing family cars, which greatly reduces the difficulty of driving. Although automatic transmissions are simple to operate, they also have disadvantages. For example, the transmission efficiency of automatic transmissions is far lower than that of manual transmissions, fuel economy is relatively poor, and driving is less enjoyable. Therefore, many automatic transmission cars are still compatible with manual mode.

[0003] The inventors of this application have found that most drivers switch from automatic mode to manual mode during driving in order to experience the pleasure of driving. However, when the vehicle is switched to manual mode, if the engine speed is very low and they want to step on the accelerator pedal to overtake, they will feel that the vehicle is underpowered and the driving experience is poor.

[0039] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0040] In order to illustrate the technical solution of the present invention, specific embodiments are provided below.

[0041] For vehicles with AT (Automatic Transmission) transmission, when the gear mode is switched from automatic mode to manual mode, the switch is made directly. For example, if the automatic mode is in sixth gear, then when switching to manual mode, it will undoubtedly switch to sixth gear.

[0042] The inventors of this application have discovered that most drivers switch to manual mode to experience the driving pleasure. However, when the engine speed is very low, after switching to manual mode, if they want to step on the accelerator pedal to overtake, they will feel that the vehicle is underpowered. The reason is that when the engine speed is usually below 1600r / min (this threshold varies depending on the engine and may be 1500r / min, 1800r / min, etc.), the engine's intake system (such as the supercharger) does not fully function, and its engine torque is low. Then, after the driver steps on the accelerator, it will feel that the vehicle speed takes a while to increase, and the driver will feel that the vehicle is underpowered. When it reaches 1600r / min, the torque reaches its maximum value. Then, after the driver steps on the accelerator, the engine outputs maximum torque, and the driver will feel that the vehicle is immediately pushed back.

[0043] Therefore, this embodiment provides a shift mode switching method, which can be integrated into a driving domain controller of a vehicle and executes a switching process when switching the shift mode.

[0044] See also Figure 1 As shown, the method includes the following steps:

[0045] Step S101 : When a vehicle is traveling, if a switching instruction input by a driver to switch a shift mode from an automatic mode to a manual mode is detected, the engine speed of the vehicle is obtained.

[0046] In this embodiment, during the vehicle operation, the driver can input a switching instruction to switch the vehicle's gear mode to manual mode through the shifter. After receiving the switching instruction, the driving domain controller can detect the engine speed of the vehicle as a judgment condition for whether downshifting is required.

[0047] Step S102: determine whether the engine speed is less than a preset lower threshold.

[0048] In this embodiment, the lower threshold value may be determined according to an output curve of the engine.

[0049] For example, the output curve of a hybrid engine is as follows: Figure 2 As shown, the hybrid engine's torque reaches maximum at 1600 r / min. Therefore, if the vehicle's hybrid engine is running at 1600 r / min or above, the driver will experience an immediate "push back" sensation as the hybrid engine outputs maximum torque upon stepping on the accelerator. If the vehicle's hybrid engine is running below 1600 r / min, the driver will feel a delay before the vehicle's speed increases, indicating insufficient power. For this hybrid engine, the lower threshold is the demarcation value of 1600 r / min. This lower threshold can be set based on actual conditions for different engines, allowing this solution to be applied to a variety of engines.

[0050] Step S103: If the engine speed is less than the lower threshold, the vehicle is downshifted. After the downshift is successful, the vehicle's gear mode is switched from automatic mode to manual mode.

[0051] In this embodiment, if the engine speed is below the lower threshold during a gear shift, the engine's intake system isn't fully functioning, resulting in low engine torque and slow speed increase after the gear shift. Therefore, this embodiment first downshifts the vehicle before switching gears. For example, if the vehicle is currently in fourth gear in automatic mode and the engine speed is 1300 rpm, when switching to manual mode, the control system first downshifts the transmission to third gear before switching to manual mode. Pressing the accelerator again in this low gear increases the engine torque, rapidly increasing vehicle speed. This switching process takes only a fraction of a second and is painless.

[0052] As can be seen, this embodiment, upon detecting a driver input command to switch the gear mode from automatic to manual, first downshifts the vehicle if the engine speed is less than the lower threshold. Once the downshift is successful, the gear mode is then switched from automatic to manual. This increases the engine's reserve torque after switching to manual mode. When the driver steps on the accelerator, the engine can deliver maximum torque, increasing vehicle speed and enhancing the driver's "push-back feeling," improving the driving experience.

[0053] The method of this embodiment can be applied to any common fuel vehicle and hybrid vehicle.

[0054] As a new type of automotive product, hybrid vehicles can achieve both reduced fuel consumption and emissions. Therefore, they will be a mainstream trend in the automotive industry for a long time to come. Hybrid vehicles utilize both an electric motor and an engine. The engine's operating point is regulated based on its performance characteristics (speed and torque), selecting a region with low fuel consumption as the engine's operating range. If the engine is not operating within this range, the motor generates power and assists to adjust the engine torque, keeping it operating within this economic range, thereby reducing emissions and fuel consumption.

[0055] The hybrid system has multiple working modes: ① Pure electric drive, in which case the engine is not working and the motor is completely driven by the battery; ② Engine-driven power generation, in which case the engine is used to generate electricity for the battery, and then the battery drives the motor; ③ The engine drives independently, the battery and the motor do not work, and the transmission system is completely driven by the engine; ④ Parallel mode, while the engine drives the transmission system, the battery also powers the electric motor, which is equivalent to the engine, battery, and generator working in parallel.

[0056] As a possible implementation, see Figure 3 As shown, if the engine speed is less than the lower threshold, the following further comprises:

[0057] Determine whether the vehicle meets the motor-assisted driving conditions;

[0058] If the vehicle meets the motor-assisted driving conditions, the motor is controlled to assist in driving the vehicle.

[0059] The process of determining whether the vehicle meets the motor-assisted driving conditions includes:

[0060] If the vehicle has a motor and the power battery level is not lower than a preset power threshold, the vehicle is determined to meet the motor-assisted driving conditions;

[0061] Otherwise, it is determined that the vehicle does not meet the motor-assisted driving conditions.

[0062] In one embodiment, when the vehicle is a hybrid, the unique advantages of hybrid vehicles can be utilized, allowing the power battery to power the electric motor to assist in power boosting. For example, if the engine speed is below 1600 rpm and the system switches to manual mode, and detects that the engine is not operating within the optimal range, it will use the electric motor to assist in power output after the gear shift. In this case, the vehicle does not need to downshift, which can further improve the vehicle's power performance. However, the prerequisite is that the vehicle is a hybrid and the power battery is fully charged.

[0063] As a possible implementation, see Figure 3 As shown, before downshifting the vehicle, the following steps may also be included:

[0064] Determine whether the vehicle has motor-assisted drive;

[0065] If there is no motor-assisted drive, the vehicle is downshifted, and after the downshift is successful, the vehicle's gear mode is switched from automatic mode to manual mode;

[0066] Otherwise, directly switch the vehicle's gear mode from automatic mode to manual mode.

[0067] In one embodiment, when the power battery of the hybrid vehicle is low on power, the motor-assisted driving conditions are not met and motor assistance cannot be provided. In this case, the above-mentioned downshift switching method can be used.

[0068] Alternatively, in one embodiment, the application vehicle is an ordinary fuel vehicle that does not have a motor at all and obviously does not meet the motor-assisted driving conditions. In this case, the above-mentioned downshift switching method can be used.

[0069] As a possible implementation method, downshifting the vehicle can be described in detail as follows:

[0070] If the current gear of the vehicle is second gear or above, the gear of the vehicle is lowered by one gear.

[0071] In this embodiment, too high a speed (e.g., above 5000 rpm) can also cause poor engine lubrication, leading to accelerated wear and shortened life. Generally, shifting down one gear can significantly increase engine torque while keeping the speed within an appropriate range. This process is also simple and does not require complex calculations.

[0072] As a possible implementation method, downshifting the vehicle can be further described as follows:

[0073] determining a maximum downshift value based on the engine speed, the current gear, and a preset upper threshold value of the engine speed; wherein the upper threshold value is greater than the lower threshold value;

[0074] Lower the vehicle's gear from the current gear to the maximum downshift value.

[0075] In this embodiment, a maximum downshift value can also be determined based on the current speed and an upper threshold (e.g., 5000 rpm). For example, if the speed allows (i.e., does not exceed the upper threshold), downshifting can be performed by two or three gears, further improving power. The specific relationship between downshifting and speed increase is also related to the vehicle's current gear position. The speed increase for each downshift varies depending on the gear position. The specific correspondence between different engines can be determined experimentally and is not limited by this application.

[0076] As a possible implementation, if the engine speed is not less than the lower threshold value, there will be no power shortage problem, and the vehicle's gear mode can be directly switched from automatic mode to manual mode.

[0077] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0078] A second aspect of the present invention provides a gear mode switching device, see Figure 4 As shown, the device 40 includes:

[0079] The acquisition module 41 is configured to acquire the engine speed of the vehicle when a switching instruction input by the driver to switch the gear mode from the automatic mode to the manual mode is detected while the vehicle is traveling.

[0080] The judgment module 42 is configured to judge whether the engine speed is less than a preset lower threshold.

[0081] The switching module 43 is configured to downshift the vehicle if the engine speed is less than a lower threshold, and to switch the vehicle's gear mode from automatic mode to manual mode after the downshift is successful.

[0082] As a possible implementation, if the engine speed is less than the lower threshold, the judgment module 42 is further configured to:

[0083] Determine whether the vehicle meets the motor-assisted driving conditions;

[0084] If the vehicle meets the motor-assisted driving conditions, the motor is controlled to assist in driving the vehicle.

[0085] As a possible implementation, before downshifting the vehicle, the switching module 43 is further configured to:

[0086] Determine whether the vehicle has motor-assisted drive;

[0087] If there is no motor-assisted drive, the vehicle is downshifted, and after the downshift is successful, the vehicle's gear mode is switched from automatic mode to manual mode;

[0088] Otherwise, directly switch the vehicle's gear mode from automatic mode to manual mode.

[0089] As a possible implementation method, determining whether the vehicle meets the motor-assisted driving conditions includes:

[0090] If the vehicle has a motor and the power battery level is not lower than a preset power threshold, the vehicle is determined to meet the motor-assisted driving conditions;

[0091] Otherwise, it is determined that the vehicle does not meet the motor-assisted driving conditions.

[0092] As a possible implementation manner, the switching module 43 is specifically configured to: if the current gear of the vehicle is the second gear or above, reduce the gear of the vehicle by one gear.

[0093] As a possible implementation, the switching module 43 is specifically configured to:

[0094] determining a maximum downshift value based on the engine speed, the current gear, and a preset upper threshold value of the engine speed; wherein the upper threshold value is greater than the lower threshold value;

[0095] Lower the vehicle's gear from the current gear to the maximum downshift value.

[0096] As a possible implementation, the switching module 43 is further configured to: if the engine speed is not less than a lower threshold value, directly switch the vehicle's gear mode from the automatic mode to the manual mode.
