RUNNING STATE CONTROLLER

摘要

PURPOSE: To optimize the inter-vehicle distance upon occurrence of a lost state or abrupt break-in and to stabilize the subsequent running control by setting an inter- vehicle distance representative of a detected inter-vehicle distance when the variation of inter-vehicle distance is shorter than a reference value but representative of an interpolated inter-vehicle distance when the reference value is exceeded. CONSTITUTION: A control unit 12 receives an inter-vehicle distance detection signal SD from a distance detecting section 11 in addition to detection signals SX from various sensors 13 and produces control signals which are delivered to a throttle valve control section 14, an EAT control section 15 and a brake control section 16 in order to control the running of a vehicle. An inter-vehicle distance interpolating section 18 detects the signals SD sequentially at a predetermined period thus detecting variation of the inter-vehicle distance. When the variation of the inter-vehicle distance is lower than a reference value, the signal SD is outputted, as it is, as an inter-vehicle distance data QDI. When the reference value is exceeded, an !interpolation processing is performed during the period where the reference value is exceeded and an interpolated inter-vehicle distance is outputted as an inter-vehicle distance data QDI thus optimizing the running control.
