1. A process for detecting an object in a vehicle which includes a distance sensor capable of detecting longitudinal and lateral distances from the subject vehicle to an object by transmitting a signal to the object and receiving the reflected signal from the object, said process comprising the steps of:

  • enclosing, into a block having a block label assigned thereto, some of the detection data detected by said distance sensor which exist within a first predetermined distance from one another;

    comparing last and current values of a center of gravity position of each block with each other for every same block label to calculate a relative speed of each block relative to the subject vehicle;

    determining object data by determining that some of the blocks which exist within a second predetermined distance and a difference between said relative speeds of which is within a preset value, are the same object; and

    averaging lateral relative speeds of the blocks in the same object to provide a lateral relative speed of the object relative to the subject vehicle.
