A method of controlling a vehicle includes detecting at least one object having a collision risk with the vehicle and changing between autonomous control levels accordingly. The control level is chosen in part based on a peril factor which includes a probability of collision (dynamics factor) and severity of the resulting potential collision. The detection may be performed by subsystem 50a which may take input from sensors 110 on the vehicle such as RADAR, LIDAR or cameras, data provided by vehicle to vehicle (V2V) communication, dedicated short range communication (DSRC). Once the object is identified 50b the information may be put into a fuzzy logic processor 50c, along with the dynamics factor 50d, the output of which determines the peril factor. The peril factor may include a weighting for different objects such vehicles, cyclists or potholes. If the peril factor exceeds a threshold the vehicle may be placed in a different mode; driver mode or autonomous mode (630 fig.18).
