A four-wheel steering vehicle including a four-wheel steering mechanism for controlling a steering of front and rear wheels based on a predetermined steering ratio property in accordance with an operation of a steering wheel, and an anti-lock braking system for controlling a braking force acted on each of the front and rear wheels to prevent the wheels from locking during a braking operation. The vehicle further comprises a stepping motor for controlling a steering ratio of a steering amount of the rear wheels to a steering amount of the front wheels in accordance with a vehicle speed based on said steering ratio property, fail detecting device for detecting an abnormal condition of the anti-lock braking system, compensating device for receiving signals from the fail detecting device and compensating the steering ratio property so that the rear wheels are steered in a direction and amount to improve a driving stability of the vehicle during a braking operation.

In a floor panel structure of a vehicle body in which a floor of an automotive vehicle is formed by a floor panel coupled to a plurality of frame members extending in substantially longitudinal and width directions of the vehicle, there are provided a panel area formed by being enclosed at least by the frame members, a heavy-weight area located at a substantially central portion of the panel area, and a peripheral area located substantially around the heavy-weight area, wherein the heavy-weight area is configured so as to be heavier than the peripheral area. Accordingly, the vibration energy transmitted from the frame members to the floor panel can be reduced and thereby the acoustic emission generated from the floor panel can be reduced.

An on-vehicle information provision apparatus is provided that visually provides a vehicle occupant with positional information on an object. The apparatus includes object setting device that sets the object, visibility determination device that determining whether or not the occupant can see the object and positional information display device that, when it is determined that the occupants can see the object, visually informs the occupant of an apparent position of the object within an actual landscape that is being seen by the occupant by displaying image information showing the object superimposed on the landscape.

A suspension-steering control apparatus is provided with suspension-characteristic changing means for changing a suspension characteristic and a rear-wheel steering mechanism for steering rear wheels of a vehicle. The suspension characteristics is such that, for example, a magnitude of a damping force of a suspension or a rolling rigidity ratio of the rear portion of the vehicle body to the front portion thereof can be changed. The rear-wheel steering mechanism is controlled on the basis of a predetermined steering characteristic. The steering-characteristic is corrected in synchronization with alteration of the suspension characteristic.

An on-vehicle information provision apparatus is provided that visually provides a vehicle occupant with an advertisement. The apparatus includes display condition setting device that sets predetermined display conditions for displaying the advertisement, condition determination device that determines whether or not the display condition applies, and advertisement display device that, when said display condition does apply, visually provides the occupant with the advertisement shown superimposed on an actual landscape being viewed by the occupant.

A fluid cylinder unit is disposed between a vehicle body and each of wheels and suspension characteristics are changed by changing the control amount of operating fluid to be supplied to or discharged from the fluid cylinder. The control amount is given based on predetermined conditions using the traveling state of the vehicle such as vehicle height, velocity of displacing the vehicle height and vertical acceleration as a parameter. A filter causes a gain of the control amount to be reduced as the frequency of vibration gets larger. A time constant of the filter is so set to become larger as the operated control amount gets larger when the control amount is smaller than a predetermined value, while the time constant is set to the predetermined value when the control amount is equal to or larger than the predetermined value. Specifically, the control amount Q is determined by the following formula: Q=Qc/(1+k.times.Qo.times.S) (where Qc is a control amount operated; k is a constant; S is a Laplace's operator; and Qo is a time constant set to Qo=Qc when Qc is lower than a predetermined value W, and to W when Qc is equal to or larger than the predetermined value W.) The filter can prevent oscillation without causing any decrease in sensitivity to control.

An operation apparatus for a vehicle automatic transmission mechanism includes an actuator for driving a hydraulic valve for switching a travel range of an automatic transmission mechanism, a control unit for controlling the actuator, and a transmission operation unit for outputting a range switching instruction to the control unit. In the preferred embodiment, the transmission operation unit includes a stroke contact type operation switch suitably mounted on a side surface of a steering column so that at least forward vehicle travel ranges can be switched by only a stretched finger of the hand of a vehicle driver who continues to maintain his grip on the steering wheel with the same hand. The operation switch can include either a rotary switch or slide switch mounted on the steering column. As an alternative embodiment, the operation switch can be an operation lever swingably arranged on the vehicle instrument panel opposing the steering wheel, but which can be operated so that at least the forward vehicle travel ranges can be switched by only a stretched finger of the vehicle driver's hand while the driver continues to maintain his grip on the wheel with the same hand.
摘要:
The panel area is formed in the substantially rectangular shape with sides thereof which extend substantially straight, by being enclosed by the frame member and the vibration restraint portion to control a vibration area, such as beads and the bent line portion, and the high-rigidity area and the low-rigidity area are formed within the panel area. Accordingly, the vibration energy can be increased at the low-rigidity area properly. As a result, the vibration energy transmitted from the frame members to the floor panel can be reduced, and thereby the acoustic emission generated from the floor panel can be reduced.
