Embodiment 1
[0035] The present invention provides a vehicle power overrun fault detection method, please refer to figure 1 , figure 1 It is a schematic flow chart of a preferred embodiment of a vehicle power overrun fault detection method provided by the present invention; specifically, the method includes:
[0036] S1. Read the actual power and the limited power of the component to be detected of the vehicle at the current moment T, and obtain the first actual power and the first limited power;
[0037] S2. When the difference between the first actual power minus the first limited power is greater than the first threshold, determine according to the actual power reduction rate and the limited power change rate of the component to be detected at the current moment T Whether the actual power of the component to be detected at the current moment T responds to the limited power;
[0038] S3. When the actual power of the component to be detected at the current moment T does not respond to t...
Embodiment 2
[0065] The present invention also provides a vehicle power overrun fault detection device, please refer to image 3 , image 3 It is a schematic structural diagram of a preferred embodiment of a vehicle power overrun fault detection device provided by the present invention; specifically, the device includes:
[0066] The obtaining module 11 is used to read the actual power and the limited power of the component to be detected of the vehicle at the current time T, and obtain the first actual power and the first limited power;
[0067] The first determination module 12 is configured to: when the difference between the first actual power minus the first limited power is greater than a first threshold, according to the actual power reduction rate and the current time T of the component to be detected Limiting the power change rate, determining whether the actual power of the component to be detected at the current moment T responds to the limited power;
[0068] The second deter...
Embodiment 3
[0079] 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 implements the vehicle power overrun fault detection method described in any one of the first embodiment above.
[0080] Specifically, there may be one or more processors and memory in the vehicle.
[0081] 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 fault detection method provided by any one of the above embodiments, for example figure 1 The step S1 shown is ...
