Abstract:
A vehicular running control apparatus, comprising:an inter-vehicle distance detection device configured to detect an inter-vehicle distance between a host vehicle and a preceding vehicle; a host vehicle running speed detection device configured to detect a host vehicle running speed; a target inter-vehicle distance setting device configured to set a target inter-vehicle distance between the host vehicle and the preceding vehicle based on the inter-vehicle distance detected by the inter-vehicle distance detection device and the host vehicle running speed detected by the host vehicle running speed detection device; a host vehicle running speed command value calculation device configured to calculate a running speed command value of the host vehicle based on the inter-vehicle distance detected by the inter-vehicle distance detection device, the host vehicle running speed detected by the host vehicle running speed detection device and the target inter-vehicle distance set by the target inter-vehicle distance setting device; a preceding vehicle acceleration detection device configured to detect an acceleration of the preceding vehicle; a host vehicle running speed command value correction device configured to multiply the acceleration of the preceding vehicle, the acceleration being detected by the preceding vehicle acceleration detection device, by a specified gain to calculate a host vehicle running speed command value correction amount, and to add the host vehicle running speed command value correction amount to the host vehicle running speed command value to calculate a corrected host vehicle running speed command value; and a host vehicle running speed control device configured to control the host vehicle running speed based on the corrected host vehicle running speed command value corrected by the host vehicle running speed command value correction device, wherein a response time constant when the host vehicle running speed control device controls the host vehicle running speed based on the corrected host vehicle running speed command value is set at the specified gain multiplied with the acceleration of the preceding vehicle.
