<p><P>PROBLEM TO BE SOLVED: To provide a vehicular real time control system 100 capable of performing the processing of adequately maintaining the vehicle-to-vehicle distance, in other words, the processing of reducing the non-matching in the real time control of a vehicle based on whether or not the transfer data are delivered between a plurality of ECUs within an adequate time. <P>SOLUTION: A vehicle-to-vehicle control ECU 2 outputs the target speed corresponding to the vehicle-to-vehicle distance between a vehicle in front and the subject vehicle and the relative speed to an engine ECU 3 based on vehicle-in-front information 50 detected by a laser radar sensor 1. The time of detecting vehicle-in-front information 50 is added to information on the target speed. The engine ECU 3 controls the operation of an actuator based on the target speed data or the like received from the vehicle-to-vehicle control ECU 2. The time in which the effective period is added to the detection time added to the reception data is compared with the present time, and it is determined whether or not the reception data are invalid for the effective period. If invalid, the target speed data are linearly extrapolated to the present value and used for the control processing. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
