Suspension control apparatus and method for vehicles
First Claim
1. A suspension control apparatus for a wheeled vehicle comprising:
- (a) position detector means for detecting a present position of the vehicle;
(b) a navigational unit for producing particular location data;
(c) suspension units respectively associated with the wheels of the vehicle and having selectively variable suspension characteristics; and
(d) a control unit which estimates in advance the arrival of the vehicle at the particular location, and which controls the suspension units so as to set the suspension characteristics to values associated with the particular location in advance of arrival of the vehicle at the particular location.

Abstract
Arrival of a vehicle at a particular location is estimated, a suspension control value for the particular location is determined, the wheel suspensions are controlled based on the determined suspension control value, and suspension control is suitably executed before the vehicle arrives at the particular location. The suspension control apparatus includes a position detector for detecting present position of the vehicle, a navigation unit for producing particular location data, suspension units, having suspension characteristics capable of control, disposed with each of the wheels, and a control unit which estimates the arrival of the vehicle at the particular location, and controls the suspension units in a manner suitable for the particular point in advance of arrival of the vehicle at that particular point.

9. A suspension control apparatus for a wheeled vehicle comprising:
-
(a) position detector means for detecting a present position of the vehicle;
(b) a navigational unit for producing data for a section of a road for which a speed limit has been set;
(c) suspension units respectively associated with the wheels of the vehicle and having selectively variable suspension characteristics; and
(d) a control unit which controls the suspension units so as to decrease the height of the vehicle when the vehicle is traveling on the road section and at a speed exceeding a vehicle speed condition based on the set speed limit.

12. A suspension control method for control of suspension units respectively associated with wheels of a vehicle, said method comprising:
-
storing, in a memory, values for suspension characteristics of the suspension units in correlation with particular locations identified as requiring adjustment of the suspension characteristics;
searching to determine a route to a destination;
determining a present position of the vehicle on the route;
generating guidance instructions to assist a driver of the vehicle in following the determined route;
determining an intent by the driver to enter one of the particular locations, based on at least the determined present position; and
in advance of the intended entry of the vehicle into the one particular location, adjusting the suspension characteristics of the suspension units in accordance with values for suspension characteristics correlated with the one particular location.
