The invention discloses a safety
system and method for preventing
drunk driving of a vehicle, the vehicle and a medium, and relates to the technical field of
safe driving. The safety
system comprises a vehicle-mounted terminal and a
cloud server which are in communication connection, the vehicle-mounted terminal comprises a detection module, a collection module, a
processing module and a control module, and the
processing module is used for verifying the identity of a driver through face data and
voice data continuously collected by the collection module and sending the identity of the driver to the
cloud server after
verification is passed. The behavior state of a driver is determined according to
voltage data continuously output by the comprehensive detection module, if the behavior state is
drunk driving, a first control instruction is generated, early warning information is uploaded to the
cloud server, and the control module is used for intelligently controlling the vehicle through the first control instruction or a second control instruction. Wherein the second control instruction is obtained by analyzing the early warning information through the cloud
server to obtain the vehicle operation data and combining the traffic environment around the vehicle and the vehicle operation data until the vehicle stably stops, and safety is ensured.
