摘要： 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.

摘要： A vehicle yawing behavior control apparatus for controlling the vehicle behavior to bring the actual vehicle yawing motion into agreement with the calculated target value calculated based on the parameters representing a condition of vehicle movement. At least vehicle yaw rate and slip angle representing an actual value of vehicle yawing motion is detected. When the detected vehicle slip angle is directed outside with respect to the vehicle movement and is greater than a reference slip angle, the calculated target vehicle yawing motion value is corrected outside with respect to the vehicle movement to a greater degree at a greater deviation of the detected vehicle slip angle from the reference slip angle. The reference slip angle is increased as the calculated target vehicle yawing motion value increases.

摘要： A control system comprises a clutch for limiting a differential action between left and right drive wheels or varying a driving torque distribution between front and rear drive axles of a four wheel drive vehicle, a sensor group and a controller for controlling an engagement force of the clutch to control the differential limiting force or the torque distribution. The sensor group senses a decelerating condition of the vehicle, a vehicle lateral acceleration and a vehicle speed. The controller increases the clutch engagement force, so as to restrain tack-in, in accordance with the lateral acceleration when the vehicle is in a decelerating operation and the lateral acceleration is high. When the vehicle speed increases, the controller increases a rate of increase of the clutch engagement force with respect to the lateral acceleration to improve both of a high speed cornering stability and a low speed steering response.

摘要： A vehicle driving assist system executes an actuation reaction force control of accelerator pedal, a driving force control or a braking force control in a manner that is appropriate in consideration of the traffic situation in which the vehicle is being driven. The vehicle driving assist system calculates a risk potential that indicates the degree of convergence between the vehicle and an obstacle existing in front of the vehicle based on a prescribed control pattern. Then, based on the risk potential, the accelerator pedal actuation reaction, the host vehicle driving force and/or the host vehicle braking force are controlled. The intent of the driver regarding acceleration and deceleration based on the actuation state of the accelerator pedal is preferably used in controlling one or all of the accelerator pedal actuation reaction, the host vehicle driving force and the host vehicle braking force.
