Problems solved by technology

However, when the vehicle is affected by various factors and there is a power overrun fault, the vehicle often cannot respond to the actual power output within the limit of the maximum allowable power. In the event of a fault, it can prevent power overrun faults to a certain extent, but it cannot effectively control the power of the vehicle when the vehicle has a power overrun fault, and cannot effectively remove the power overrun fault

Embodiment 1

[0051] see figure 1 , figure 1 It is a schematic flowchart of a preferred embodiment of a vehicle power overrun control method provided by the present invention; specifically, an embodiment of the vehicle power overrun control method in the embodiment of the present invention includes:

[0052] S1. After determining that the vehicle has a power overrun fault, sequentially enter the first control phase, the second control phase, and the third control phase of the power overrun control phase; and read the actual power and the actual power of the vehicle at the current moment T in real time. The power is limited, and the first actual power and the first limited power are obtained.

[0053] It should be noted that, before step S1 is executed, the vehicle detects in advance whether there is a power overrun fault in the vehicle according to a certain detection mechanism. For example, when the actual power of the vehicle exceeds the limit power, it is determined that the vehicle ha...

Embodiment 2

[0090] The present invention also provides a vehicle power overrun control device, please refer to image 3 , image 3 It is a structural schematic diagram of a preferred embodiment of a vehicle power overrun control device provided by the present invention; specifically, the device includes:

[0091] The control module 100 is configured to enter into the first control stage, the second control stage and the third control stage of the power overrun control stage sequentially after determining that the vehicle has a power overrun fault; and read the current time T of the vehicle in real time The actual power and the limited power to obtain the first actual power and the first limited power; wherein, the control module 100 specifically includes:

[0092] The first control unit 101 is configured to reduce the first limited power according to a preset reduction algorithm in the first control stage to obtain the limited power output by the vehicle at the next time T+Δt until the f...

Embodiment 3

[0113] The present invention also provides a vehicle, please refer to Figure 4 , Figure 4 It is a schematic structural diagram of a preferred embodiment of a vehicle provided by the present invention; the vehicle includes a processor 10, a memory 20, and a computer program stored in the memory 20 and configured to be executed by the processor 10, When the processor 10 executes the computer program, it realizes the power overrun control method of the vehicle as described in any one of the first embodiment above.

[0114] Specifically, there may be one or more processors and memory in the vehicle.

[0115] A vehicle provided in this embodiment includes: a processor, a memory, and a computer program (such as Figure 4 computer program 1, computer program 2, ...). When the processor executes the computer program, it implements the steps in the vehicle power overrun control method provided by any one of the above embodiments, for example figure 1 In step S3 shown, in the seco...

Abstract

The invention discloses a vehicle power overrun control method, device and vehicle, wherein the method includes: after judging that the vehicle has a power overrun fault, entering the power overrun control stage; in the first control stage, according to the preset The reduction algorithm reduces the first limited power to obtain the limited power of the vehicle at the next moment, and enters the second control stage when the first actual power is not greater than the initial limited power; in the second control stage, the vehicle is output according to the first limited power Limit power at a moment, until the difference between the initial limit power minus the first actual power is greater than the difference threshold, enter the third control stage; in the third control stage, increase the first limit power according to the preset increase algorithm , to obtain the limited power of the vehicle at the next moment, until the first limited power reaches the initial limited power, the power overrun control phase ends. The invention can effectively control the power of the vehicle when the vehicle has a power overrun fault.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle power overrun control method, device and vehicle. Background technique [0002] In the power transmission of the vehicle, it is generally required that the actual power of the vehicle does not exceed the limited power, so as to prevent the over-discharge of the vehicle power and affect the safety and reliability of the vehicle operation. However, due to factors such as power loss during power transmission, the state of the vehicle's battery, or the operating environment of the vehicle, the actual power of the vehicle may exceed the limited power, resulting in a power overrun fault. Therefore, when the vehicle has a power overrun fault, it is particularly important to take effective control measures in time for the normal operation of the vehicle. [0003] In the prior art, the actual power output by the vehicle is only controlled according to the maximum allowable pow...
