The embodiment of the invention provides a vehicle driving early warning method and device. The vehicle driving early warning method provided by the embodiment of the invention comprises the followingsteps of determining a target vehicle and a target driving vehicle located on the same target driving road as the target vehicle; acquiring motion parameters of the target vehicle, motion parametersof the target driving vehicle and driving safety distance parameters corresponding to the target driving road; determining a first collision time parameter corresponding to the driving safety distanceparameter according to the motion parameter of the target vehicle, the motion parameter of the target driving vehicle and the driving safety distance parameter; and obtaining the vehicle attribute parameters of the target vehicle and the vehicle attribute parameters of the target driving vehicle. The method is advantaged in that accuracy of the determined collision time early warning threshold for vehicle driving early warning is improved, so precision of vehicle driving early warning for the vehicle is improved.
