摘要:
A vehicle having learning control includes a running condition detecting device for detecting a driving condition of the vehicle, a running characteristic control device for controlling a control gain to change a running characteristic of the vehicle and a gain control device for learning the running characteristic of the vehicle to change the control gain. The running characteristics of the vehicle can be controlled corresponding to various running conditions.

A system for steering a rear wheel of a vehicle having a mechanism for altering a steering ratio, .THETA.S, based on an amount of steering of the rear wheel to an amount of steering a front wheel. The system is disposed in an interconnecting mechanism for mechanically interconnecting the mechanism for steering the front wheel with the mechanism for steering the rear wheel. The value of .THETA.S is set by the following formula:.THETA.S=C1+B.multidot.C3.multidot..vertline.Y.vertline.-C4.multidot..vertline.dY.vertline.where .THETA.S is a steering ratio;Y is a yaw rate of a vehicle body;dY is a yaw acceleration of the yaw rate;C1 is a basic steering characteristic term;C3 is a yaw rate control gain;C4 is a yaw acceleration control gain; andB is a correction coefficient control gain term.The value of B increases when the amount of steering of the front wheel is small and decreases when the amount of steering of the front wheel is large.

A map and other information distribution system for distributing map information and information other than map information is disclosed. The map and other information distribution system comprises an information center including a database storing map information and information other than map information, and a transmitter for transmitting at least said map information under a fee-based navigation contract concluded beforehand, and a mobile navigation system including a location detector for detecting the present location of a mobile unit, a receiver for receiving at least the map information from the information center under the fee-based navigation contract concluded beforehand, and a controller for displaying the map information around the present location of the mobile unit on a display device.
摘要:
A suspension system has a link mechanism, disposed between a wheel support and a car body, for suspending the wheel support from the body so as to allow a wheel, related to steering, to swing about a center axis relative to the body. The link mechanism is caused to change a height of an instantaneous center of a swing of the wheel from the ground according to degrees of turn, such as steered angles, so as to maintain a height of the instantaneous center at a substantially fixed height from the ground.

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.

In order to make better use of personal information manager data and to improve the convenience for the user, in cases where such personal information manager data is used in a vehicle V, the personal information manager data including position data and time data and traffic information are input from outside the vehicle V so as to guide the user using the vehicle V along a travel route based on the personal information manager data and in association with the position data, whereby it is possible to appropriately guide the user using the vehicle V along the travel route according to the position data of the personal information manager data.
摘要:
A navigation unit 1 sends map image information representing a map image of an area around a current position of an automobile in which the unit 1 is installed to a communication apparatus 9 with which the unit 1 is communicating, if the communication apparatus 9 does not have geographical data. The map image information includes information such as a symbol image that allows the current position of the navigation unit 1 to be identified. The data format of the map image information is a data format that allows the information to be reproduced in an ordinary personal computer.
摘要:
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.
摘要:
An audio apparatus (audio system) made up of the car-mounted audio apparatus 100 and portable audio apparatuses 200a and 200b transmits/receives contents data such as music via radio communication. As the communication system in this in-car radio communication, a short-distance data communication system is used, which allows respective apparatuses to recognize and authenticate with one another and perform data communication between those apparatuses.
