Abstract

The application relates to the technical field of internet of vehicles, in particular to a method, a device and equipment for waking up a vehicle. The method comprises the steps of monitoring network state information of a first Internet of things network card and a second Internet of things network card at a vehicle terminal in real time, determining a target Internet of things network card from the first Internet of things network card and the second Internet of things network card according to the network state information when a vehicle terminal awakening instruction is received, awakening the vehicle based on the target Internet of things network card, and determining an awakening result. In the embodiment of the application, a card with better network state in two internet of things cards is dynamically selected to execute wakeup by combining a double-card collaborative wakeup mechanism with a signal priority and redundancy backup strategy, and another card is automatically switched to retry after failure. The wake-up success rate is improved, the problem of wake-up failure caused by poor signal of a single card in the prior art is solved, and the stable landing of the core business of the Internet of vehicles is ensured.
