A data generating system and a method to be used in a host vehicle for generating distance data as to the distance between the host vehicle and a target object travelling in the predicted path of the host vehicle and velocity data as to the velocity of the target object. When a target object is detected, the distance data is set to correspond to a measured distance value, the velocity data is set to correspond to a value determined based on a measured value of the relative velocity of the target object and the velocity of the host vehicle, and these data are stored in a memory. When the target object ceases to be detectable at the same time as the host vehicle is travelling in a curve, a value of the distance between the host vehicle and the target object is repeatedly estimated based on the latest distance and velocity data stored in the memory and the velocity of the host vehicle, whereupon the distance data is set to correspond to the estimated value and stored in the memory.
