Abstract
An adaptive cruise control system for a host vehicle is arranged to calculate a target inter-vehicle distance between the preceding vehicle and the host vehicle, to calculate a target vehicle speed and a first target driving torque based on the inter-vehicle distance and the target inter-vehicle distance, to calculate a second target driving torque based on the target vehicle speed and the host vehicle speed, to generate a torque select signal based on the host vehicle speed, to select one of the first and second target driving torques based on the torque select signal, to match the selected target driving torque with a previous target driving torque when the target driving torque is changed, and to generate driving/braking force based on the selected target driving torque.
