The invention discloses a vehicle control method, system and device and belongs to the technical field of automatic vehicle driving. The method includes the steps that when a vehicle is in an automatic driving mode, first control behavior information is acquired through an intra-vehicle sensing system; whether the first control behavior information belongs to stress control behavior information ornot is recognized; and if the first control behavior information does not belong to the stress control behavior information, the automatic driving mode is switched to manual driving mode. Whether thefirst control behavior information belongs to the stress control behavior information or not is recognized, the situation that the vehicle control device mistakenly judges stress reaction behavior information generated by a driver under a stress reaction as normal control behavior information, a vehicle control right is mistakenly given to the driver, and the driver is caught in danger due to theimproper control behavior under the stress reaction is avoided, the vehicle is more intelligently switched to the manual driving mode from the automatic driving mode, and the safety performance of the vehicle is improved.
