An adaptive cruise control system for a motor vehicle includes a forward looking object detecting arrangement for simultaneously detecting several target objects moving in the predicted path and adjacent paths of the equipped vehicle. The detecting arrangement is arranged to continuously monitor velocity and distance to each of the target objects, and a processing arrangement processes signals from the detecting means to provide information of distance to and relative speed of vehicles travelling in front of the equipped vehicle. The processing arrangement repeatedly generates velocity control signals based on the information of distance to and relative speed of vehicles travelling in front of the equipped vehicle. An arrangement controls velocity of the vehicle in response to the control signals from the processing arrangement. The processing arrangement calculates a distance in time from the equipped vehicle to a virtual target vehicle, the distance to and velocity of the virtual target vehicle being calculated on basis of the number of vehicles in the group, the spread in distance of the group, and thus the vehicle density of the group, and the variability of positions in the group, such that the algorithm of the processing means decides from the above parameters on the allowed deviations in time distance, wherein the processing arrangement is arranged to produce a signal to the velocity control arrangement based on the calculated distance in time between the equipped vehicle and the virtual vehicle. 2. An adaptive cruise control system according to claim 1 , wherein the signal produced by the processing means to the means for controlling the velocity represents a value of the desired velocity.3.

An ECU is mounted in a vehicle including an in-cylinder injection type engine having an EGR device and a motor. The ECU calculates vehicular requested power Preq and the ECU calculates a requested engine operating point OPreq based on the vehicular requested power Preq, and if the requested engine operating point OPreq falls within an EGR range, the ECU sets the requested engine operating point OPreq exactly as a commanded engine operating point OPcom, whereas if the requested engine operating point OPreq falls within a non-EGR range, the ECU corrects the requested engine operating point OPreq to fall within the EGR range and sets the corrected engine operating point as the commanded engine operating point OPcom. The ECU then controls the engine and the motor so that an actual engine operating point coincides with the commanded engine operating point OPcom while satisfying the vehicular requested power Preq. 1.
