VEHICLE CONTROL DEVICE

A brake assist controller determines that an operating condition for a brake assist control is satisfied if time to collision (TTC) calculated by dividing an inter-vehicle gap by a relative speed is equal to or smaller than a reference time to collision (reference TTC), and if the time to collision...

Zusammenfassung:	A brake assist controller determines that an operating condition for a brake assist control is satisfied if time to collision (TTC) calculated by dividing an inter-vehicle gap by a relative speed is equal to or smaller than a reference time to collision (reference TTC), and if the time to collision (TTC) is larger than the reference TTC, the brake assist controller determines that the operating condition for the brake assist control is satisfied if a time headway (THW) calculated by dividing the inter-vehicle gap by a vehicle speed of an own vehicle is equal to or smaller than a reference time headway (reference THW).
