The invention relates to the technical field of automobiles, and provides a vehicle software upgrading method and device based on multi-channel data transmission and an automobile. The method comprises the steps of configuring a transmission strategy for a data packet in response to an OTA upgrade request, wherein the transmission strategy comprises transmission channels corresponding to data fragments of the data packet; if the abnormal probability of a target transmission channel is larger than a first preset threshold value, a corresponding standby channel is configured for the target transmission channel, the abnormal probability of the standby channel is smaller than that of the target transmission channel, and the target transmission channel is at least one of the transmission channels corresponding to the data fragments; and when each transmission channel is utilized to transmit the corresponding data fragment, if it is detected that the target transmission channel is abnormal, the corresponding standb
