The embodiment of the invention provides a vehicle braking failure early warning method and device and a vehicle, and the method comprises the steps: when the vehicle is in an automatic driving state or a cruising state, detecting whether a braking system of the vehicle has braking failure or not; if it is detected that the braking system has the braking failure, the existing braking failure type is determined; based on a plurality of pre-stored early warning strategies, a target early warning strategy matched with the brake failure type is determined, and the multiple early warning strategies comprise a brake build-up braking early warning strategy of the brake system, an EPB caliper mechanical braking early warning strategy of the brake system and a reverse dragging braking early warning strategy of a power domain system; and based on the target early warning strategy, controlling the vehicle to execute an early warning action so as to remind a driver to take over the vehicle. According to the technical scheme provided by the embodiment of the invention, the driver can be warned to take over the vehicle in time when the vehicle fails to brake, so that the accident rate is reduced.
