[0002] Currently, during driving, the driving ability of a vehicle is determined by the real-time maximum driving ability of components. When the ability of a component changes, it directly affects the change in the driving ability of the vehicle. However, when the driving ability of the vehicle increases from small to large with the ability of the component, there is a lack of interaction and communication with the driver, which causes the driver to feel an unexpected sense of acceleration, leading to discomfort for the driver. In some more serious cases, the current method for regulating the driving ability of a vehicle may even cause traffic accidents and unnecessary losses. Summary of the Invention

[0019] Determining whether the vehicle continues to drive;

[0020] When the vehicle continues to drive, the step of determining whether the difference between the component driving ability and the vehicle driving ability is greater than the preset update comparison coefficient is executed;

[0021] When the vehicle does not continue to drive, the automatic driving is ended.

[0041] S101. Detect whether an acceleration switching instruction is received. If so, execute step S102; if not, end this process.

[0042] In this embodiment, the acceleration switching instruction is used to control the vehicle to switch from a non-accelerated state to an accelerated state.

[0043] S102. Determine whether the difference between the component driving ability and the vehicle driving ability is greater than a preset update comparison coefficient. If so, execute steps S104 - S107; if not, execute step S103.

[0044] In this embodiment, when the vehicle is driving, the currently used driving ability is referred to as the vehicle driving ability P t , and the component driving ability is represented by C A . In the theoretical state, P t = C A .

[0045] In this embodiment, when the component driving ability C A increases from small to large during driving, at this time, the vehicle driving ability P t remains unchanged first.

[0046] In this embodiment, when the driver's demand changes from non-acceleration to acceleration, at this time, judge the magnitude of (component driving ability C A - vehicle driving ability P t ) and the preset update comparison coefficient i. It can be understood that this process is a process of comparing the magnitudes of (C A - P t ) and i.

[0047] S103. Update the vehicle driving ability based on the component driving ability, and execute step S102.

[0049] S104. Calculate based on the obtained vehicle parameter values to obtain a vehicle driving coefficient.

[0050] In this embodiment, the vehicle parameter values include vehicle weight, transmission ratio, wheel radius, vehicle resistance curve, motor external characteristics, etc.

[0051] In this embodiment, this method can calculate a coefficient k related to the vehicle driving performance (i.e., the vehicle driving coefficient) based on the vehicle parameter values.

[0052] In this embodiment, when (C A - P t) If it is greater than or equal to i, then update the vehicle driving ability P t Update it to the latest driving ability P (t+1) .

[0053] S105. Calculate the sum of the vehicle driving ability and the vehicle driving coefficient to obtain the latest driving ability.

[0054] In this embodiment, P (t+1) = P t + k, where k is the vehicle driving coefficient.

[0055] S106. Update the vehicle driving ability based on the latest driving ability.

[0056] S107. Determine whether the vehicle driving ability is less than the component driving ability. If so, execute step S102; if not, execute steps S108 - S109.

[0057] In this embodiment, when P (t+1) < C A execute step S102.

[0058] S108. Update the vehicle driving ability based on the component driving ability.

[0059] In this embodiment, when P (t+1) ≥ C A let P (t+1) = C A .

[0060] S109. Determine whether the vehicle continues to drive. If so, execute step S102; if not, execute step S110.

[0061] S110. End autonomous driving.

[0062] Implementing this implementation method can well combine the change of driving ability with the driver's intention, thereby giving a driving experience with the best smoothness.

[0063] In this embodiment, the execution subject of this method can be a computing device such as a computer or a server, and no limitation is made in this embodiment.
