Abstract:
An adaptive cruise control (ACC) system for a host vehicle, comprising:a vehicle speed detector detecting a vehicle speed of the host vehicle; a distance detector detecting an inter-vehicle distance between a preceding vehicle and the host vehicle; a driving/braking force generator generating driving/braking force; and a controller connected to said vehicle speed detector, said distance detector and said driving/braking force generator, said controller, calculating a target inter-vehicle distance between the preceding vehicle and the host vehicle based on the detected vehicle speed, calculating a target vehicle speed and a first driving torque based on the inter-vehicle distance and the target inter-vehicle distance, calculating a second driving torque based on the host vehicle speed and the target vehicle speed, generating a torque select signal based on the host vehicle speed, selecting one of the first and second driving torques responsive to the torque select signal, determining a target driving torque based on the selected one of the first and second driving torques and the difference between the first and second driving torques, and outputting the target driving torque indicative signal to said driving/braking force generator.
