Abstract
An inter-vehicle distance maintenance supporting system may include an operational reactive force generating device that generates an operational reactive force on a driving operational equipment based on a first inter-vehicle distance threshold. A driving operational equipment state detector detects an operational state of the driving operational equipment and acceleration intent of the driver. An engine controller controls an engine torque corresponding to the operational state of the driving operational equipment. An engine torque correcting device decreases the engine torque before the operational reactive force is generated. The decrease correction is suppressed when the inter-vehicle distance is greater than a second inter-vehicle distance threshold that is larger than the first inter-vehicle distance, and the driving operational equipment state detector detects the acceleration intent of the driver.
