Abstract
An information system for a host vehicle is comprised of an accelerator manipulation detecting device that detects an accelerator manipulation quantity of an accelerator according to which a driver demand driving force is generated by an internal combustion engine, an object detecting unit that detects an object ahead of the host vehicle; and a controller which is connected to the accelerator manipulation detecting device and the object detecting unit. The controller determines a contact possibility that the host vehicle will contact with an object ahead of the host vehicle, on the basis of information from the objecting detecting unit, and corrects a driving-force relationship between the driver demand driving force and the accelerator manipulation quantity according to the contact possibility. The controller may include a processor that employs a simulation of a virtual member in front of the host vehicle which provides feedback to a driver of the host vehicle based on a relationship between the host vehicle and an object ahead of the host vehicle. The virtual member may be, for example, a virtual spring.
