Summary: | The invention relates to the technical field of vehicle testing, and discloses a catalyst degradation time determination method and device, equipment and a storage medium, and the method comprises the steps: obtaining the initial temperature of a catalyst; determining a transient catalyst center temperature according to a target correction parameter, a preset temperature difference and the initial temperature of the catalyst; determining the catalyst degradation time of the target vehicle through a preset catalyst degradation time relationship and the transient catalyst center temperature; the transient catalyst center temperature is determined through the target correction parameter, the preset temperature difference and the initial temperature of the catalyst, and then the catalyst degradation time is determined based on the preset catalyst degradation time relation and the transient catalyst center temperature, so that compared with the prior art that the degradation time is determined through the catalyst |
