A redundancy control method for an automatic driving system, an automatic driving system, an automobile, a controller, and a computer readable storage medium, for use in keeping driving along a lane centerline if a fault occurs in an automatic driving system and the fault does not exceed tolerance. The method comprises: if an automatic driving function is activated, according to information collected by a front-view camera and a radar, fitting a safety path equation for causing a vehicle to drive along a lane centerline and determining the lane width of a lane where the vehicle is currently located; according to a coefficient of the safety path equation and the determined lane width, determining an offset area where the vehicle is currently specifically located; according to the offset area where the vehicle is located and whether the vehicle has activated a first redundancy safety control module function in a previous control period, determining a current fault level of a main control subsystem; and accordin
