Abstract
An in-vehicle apparatus and method generates a pseudo-travel locus that is used to perform a driving support control. The in-vehicle apparatus has a pseudo-locus generator for generating the pseudo-travel locus of a subject vehicle and a communication controller for controlling a transmitter to transmit the pseudo-travel locus of the subject vehicle. The pseudo-travel locus is generated from a travel locus of a lead vehicle and a current position of the subject vehicle. Therefore, a portion of the travel locus of the subject vehicle is similar to an actual travel locus of the subject vehicle. Thus, when the pseudo-travel locus is transmitted as a travel locus of the subject vehicle, nearby vehicles may perform a driving support control based on the pseudo-travel locus of the subject vehicle. As a result, the actual travel locus of the subject vehicle is not disclosed.
