Title: Controller for vehicle
Inventor: HASHIMOTO MASAHIRO
IPC: B60W30/00
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To more suitably set timing for operating a warning unit for avoiding a contact with a front obstacle. SOLUTION: Whenever the driver of a self-vehicle 1 decelerates, a vehicle distance (d) with a front vehicle 2, relative speed Vr, self-vehicle speed Vo and brake stepping quantity Brk are stored with correlations. A specified vehicle distance dw as operation start timing for operating a warning unit W is decided by using a normalization logic expression containing brake stepping quantity Brk in a stabilization item. The decided specified vehicle distance dw can be made into a mapped system with self-speed Vo and relative speed Vr as parameters, for example. The reflection degree of stepping quantity Brk against the decision of the specified vehicle distance dw can be taken large as Brk is large. When an actual vehicle distance (d) becomes smaller than the specified vehicle distance dw, the warning unit W is operated.
