BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 2 It shows a schematic diagram of the vehicle control device provided by an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Aiming at the problem in the prior art that the driver repeatedly quickly stepping on and releasing the throttle during driving will cause vehicle impact phenomenon, the present invention provides a vehicle control method, device and vehicle.

[0034] As Figure 1 shown, an embodiment of the present invention provides a vehicle control method, including:

[0035] Step 101: Monitor the change time of the throttle opening of the vehicle;

[0036] Step 102: When the change time of the throttle opening meets the condition for prohibiting shifting, control the vehicle to prohibit shifting.

[0037] In this embodiment, by monitoring the change time of the throttle opening of the vehicle, the vehicle control unit (such as TCU (Transmission Control Unit, automatic transmission control unit)) can better understand the driver's operation at this time, and then when the driver repeatedly performs the driving operations of quickly stepping on and releasing the throttle, a control to inhibit shifting is made, effectively avoiding the occurrence of vehicle impact phenomenon.

[0038] Optionally, the change time of the throttle opening includes throttle rising time, throttle top staying time, throttle falling time and throttle bottom staying time;

[0039] Among them, the throttle rise time is the time difference between the first moment and the second moment, the throttle top dwell time is the time difference between the second moment and the third moment, the throttle fall time is the time difference between the third moment and the fourth moment, and the throttle bottom dwell time is the time difference between the fourth moment and the fifth moment;

[0040] The first moment is the moment when the throttle opening starts to be greater than the first preset opening threshold, the second moment is the moment when the throttle opening starts to be greater than the second preset opening threshold, the third moment is the moment when the throttle opening starts to be less than the second preset opening threshold, the fourth moment is the moment when the throttle opening starts to be less than the first preset opening threshold, and the fifth moment is the moment when the throttle opening starts to be greater than the first preset opening threshold again. The first preset opening threshold is less than the second preset opening threshold.

[0041] Here, the fifth moment is the moment when the throttle opening starts to be greater than the first preset opening threshold again, which is relative to the first moment when the throttle opening starts to be greater than the second preset opening threshold. That is to say, when the moment when the throttle opening starts to be greater than the first preset opening threshold is recorded as the first moment, after the first moment, the moment when the throttle opening starts to be greater than the first preset opening threshold again is recorded as the fifth moment.

[0042] In this embodiment, the specific values of the first preset opening threshold and the second preset opening threshold can be set according to the specific situation of the vehicle, where the first preset opening threshold is less than the second preset opening threshold.

[0043] Furthermore, the following calibration quantities can be set respectively according to the specific situation of the vehicle:

[0044] The first preset time, that is, the standard throttle rise time: It represents the standard time experienced when the throttle opening rises from the first preset opening threshold to the second preset opening threshold during the rising process.

[0045] The second preset time, that is, the standard throttle top dwell time: It represents the standard time experienced from the moment when the throttle opening exceeds the second preset opening threshold until the throttle opening drops back to the second preset opening threshold again.

[0046] The third preset time, that is, the standard throttle fall time: It represents the standard time experienced when the throttle opening drops from the second preset opening threshold to the first preset opening threshold during the falling process.

[0047] The fourth preset time, that is, the standard throttle bottom dwell time: It represents the standard time experienced from the moment when the throttle drops below the first preset opening threshold until the throttle opening rises to the first preset opening threshold again.

[0048] Optionally, the throttle opening change time satisfying the gearshift prohibition condition includes:

[0049] Monitoring and obtaining a preset number of the throttle rising times, a preset number of the throttle top staying times, a preset number of the throttle falling times, and a preset number of the throttle bottom staying times respectively; and each of the throttle rising times is less than or equal to a first preset time, each of the throttle top staying times is less than or equal to a second preset time, each of the throttle falling times is less than or equal to a third preset time, and each of the throttle bottom staying times is less than or equal to a fourth preset time.

[0050] Here, the preset number can be set according to the specific situation of the vehicle. For example, the preset number can be set to 2 or 3. When the preset number is set to 2, the throttle opening change time satisfying the gearshift prohibition condition is: 2 throttle rising times, 2 throttle top staying times, 2 throttle falling times, and 2 throttle bottom staying times are monitored and obtained, and each of the monitored throttle rising times is less than or equal to the first preset time, each of the throttle top staying times is less than or equal to the second preset time, each of the throttle falling times is less than or equal to the third preset time, and each of the throttle bottom staying times is less than or equal to the fourth preset time.

[0051] In this embodiment, when it is monitored that the throttle opening change time satisfies the gearshift prohibition condition, it indicates that the driver is currently repeatedly performing the driving operations of quickly stepping on and releasing the throttle. At this time, in order to avoid the occurrence of vehicle impact phenomenon, the vehicle can be controlled to inhibit gearshift.

[0052] It can be understood that the throttle rising time, the throttle top staying time, the throttle falling time, and the throttle bottom staying time are the actually monitored times. Specifically:

[0053] The throttle rising time, that is, the actual throttle rising time: represents the actual time experienced when the throttle opening rises from a first preset opening threshold to a second preset opening threshold during the rising process.

[0054] The throttle top staying time, that is, the actual throttle top staying time: represents the actual time experienced from the moment when the throttle opening exceeds the second preset opening threshold until the throttle opening drops back to the second preset opening threshold again.

[0055] The throttle falling time, that is, the actual throttle falling time: represents the actual time experienced when the throttle opening drops from the second preset opening threshold to the first preset opening threshold during the falling process.

[0056] The throttle bottom dwell time, i.e. the actual throttle bottom dwell time, represents the actual time from the moment the throttle drops below the first preset opening threshold until the throttle opening rises to the first preset opening threshold.

[0057] Optionally, controlling the vehicle to prohibit gear shifting includes:

[0058] When the vehicle is in a non-shifting state, the vehicle is controlled to prohibit shifting; or when the vehicle is in a shifting state, the vehicle is controlled to prohibit shifting after monitoring that the vehicle shifting is completed.

[0059] That is to say, when it is necessary to control the vehicle to prohibit gear shifting, there are two situations: situation one, if the vehicle is in a gear shifting state, wait until the vehicle gear shifting is completed before executing the control to prohibit gear shifting; situation two, if the vehicle is in a non-gear shifting state, execute the control to prohibit gear shifting immediately.

[0060] Optionally, the vehicle control method further includes:

[0061] When the vehicle is in a gear shifting prohibited state and the throttle opening variation time of the vehicle satisfies a second preset condition, the control of prohibiting gear shifting of the vehicle is cancelled after a fifth preset time.

[0062] Here, when the vehicle is in the shift-inhibited state, if the second preset condition is met (i.e., the condition for exiting the shift-inhibited state), an operation is performed: the shift-inhibiting restriction is continued for a predetermined time (i.e., a fifth preset time, which can be set based on the specific situation), and then the shift-inhibiting restriction is lifted to maintain smooth vehicle driving. In other words, the fifth preset time is the duration for which the shift-inhibiting restriction is maintained (before the shift-inhibiting restriction is released).

[0063] Optionally, the throttle opening change time of the vehicle satisfies a second preset condition, including at least one of the following:

[0064] The throttle rise time is greater than a first preset time;

[0065] The throttle top dwell time is greater than a second preset time;

[0066] The throttle drop time is greater than a third preset time;

[0067] The throttle bottom dwell time is greater than a fourth preset time.

[0068] In this embodiment, when any one of the above conditions is met, it indicates that the driver no longer wants to quickly step on or release the accelerator. In this way, the control of prohibiting the vehicle from shifting gears can be cancelled after the fifth preset time.

[0069] In the embodiments of the present invention, by monitoring the change time of the throttle opening of the vehicle, when the driver repeatedly performs the driving operations of quickly stepping on and releasing the throttle, a control to inhibit gear shifting can be made, effectively avoiding the occurrence of vehicle impact phenomena.

[0071] A monitoring module 210, configured to monitor the change time of the throttle opening of the vehicle;

[0072] A processing module 220, configured to control the vehicle to prohibit gear shifting when the change time of the throttle opening meets the gear shifting prohibition condition.

[0073] Optionally, the change time of the throttle opening includes a throttle rising time, a throttle top staying time, a throttle falling time, and a throttle bottom staying time;

[0074] Wherein, the throttle rising time is the time difference between a first moment and a second moment, the throttle top staying time is the time difference between the second moment and a third moment, the throttle falling time is the time difference between the third moment and a fourth moment, and the throttle bottom staying time is the time difference between the fourth moment and a fifth moment;

[0075] The first moment is the moment when the throttle opening starts to be greater than a first preset opening threshold, the second moment is the moment when the throttle opening starts to be greater than a second preset opening threshold, the third moment is the moment when the throttle opening starts to be less than the second preset opening threshold, the fourth moment is the moment when the throttle opening starts to be less than the first preset opening threshold, the fifth moment is the moment when the throttle opening starts to be greater than the first preset opening threshold again, and the first preset opening threshold is less than the second preset opening threshold.

[0076] Optionally, the change time of the throttle opening meeting the gear shifting prohibition condition includes:

[0077] Respectively monitoring and obtaining a preset number of the throttle rising times, a preset number of the throttle top staying times, a preset number of the throttle falling times, and a preset number of the throttle bottom staying times; and each of the throttle rising times is less than or equal to a first preset time, each of the throttle top staying times is less than or equal to a second preset time, each of the throttle falling times is less than or equal to a third preset time, and each of the throttle bottom staying times is less than or equal to a fourth preset time.

[0078] Optionally, the processing module 220 includes:

[0079] A first control unit, configured to control the vehicle to prohibit gear shifting when the vehicle is in a non-gear shifting state;

[0080] A second control unit, configured to control the vehicle to prohibit gear shifting after monitoring that the vehicle has completed gear shifting when the vehicle is in a gear shifting state.

[0081] Optionally, the vehicle control device further includes:

[0082] A release module, configured to cancel the control of prohibiting gear shifting of the vehicle after a fifth preset time when the vehicle is in a state of prohibiting gear shifting and the change time of the throttle opening of the vehicle meets a second preset condition.

[0086] The throttle falling time is greater than a third preset time;

[0087] The throttle staying time at the bottom is greater than a fourth preset time.

[0088] In an embodiment of the present invention, by monitoring the change time of the throttle opening of the vehicle, control for inhibiting gear shifting can be made when the driver repeatedly performs rapid stepping on and releasing of the throttle, effectively avoiding the occurrence of vehicle impact phenomena.
