Method and system for predictive vehicle systems performance selection for enhanced maneuverability
First Claim
1. A host vehicle having predictive enhanced maneuverability comprising:
- a suspension having a normal mode and a sport mode;
a steering system having different operating modes;
a suspension and steering mode selection module connected with said suspension and said steering system;
a time dependent headway (TDH) input operatively associated with said module, said TDH being in relation to a preceding vehicle;
a traffic density (TRD) input operatively associated with said module; and
a forward collision warning alert (FCWA) input operatively associated with said module, said module having a TDH output algorithm in which, when TDH is closer to 0.0, the host vehicle is identified as being nearer to the preceding vehicle and normal mode is engaged, and, when TDH is closer to 1.0, the host vehicle is farther from the preceding vehicle and sport mode is engaged.

Abstract
A predictive enhanced maneuverability system providing enhanced timely delivery of vehicle performance selection of chassis, and steering modes for potential predicted safety collisions is disclosed. The primary inputs of the disclosed invention include a determination of the proximity to a preceding vehicle, the density of the surrounding traffic, a forward collision warning alert, and the predictive enhanced maneuverability decision sub-system for vehicle mode selection. The system of the disclosed invention provides a customized vehicle dynamics chassis and steering dynamic mode output, based on a predicted decision about vehicle potential for collision, for improved driver maneuverability and safety. In addition, the disclosed invention provides an improved system and method for incorporating the time dependent headway, forward collision warning alert, and the traffic density for chassis collision-mode embedded decision-making. The predictive enhanced maneuverability decision-module allows vehicle dynamics mode selection to be tailored based on proximity to a potential collision.

7. A vehicle having predictive enhanced maneuverability comprising:
-
a suspension having original, normal and sport modes; a steering system having original, normal and sport modes; a suspension and steering mode selection module connected with said suspension and said steering system, said module incorporating a rule-based algorithm; a plurality of sensors for distinguishing between low and high time dependent headway (TDH) and for distinguishing between low and high vehicle traffic density (TDR), said sensors being operatively associated with said module, said sensors providing input to said module for selecting among said modes appropriate to respond to a potential collision scenario, whereby when both TDH and TDR are identified as low, said sport mode is selected by said module for both said suspension and said steering system and when said TDH is low and said TDR is high, said sport mode is selected by said module for said suspension and said normal mode is selected for said steering system. - View Dependent Claims (8, 9, 10, 11, 12, 13)

14. A method for providing predictive enhanced maneuverability in a host vehicle having a suspension and steering system with different operating modes, the method comprising the steps of:
-
forming a system including a suspension having sport and normal modes, a steering system having sport and normal modes, a suspension and steering mode decision selection module and a plurality of sensors for determining time dependent headway (TDH), local vehicle traffic density (TRD) and position, said sensors being operatively associated with said decision module and providing input thereto; and assigning a value of TDH of between 0.0 and 1.0, whereby if TDH is closer to 0.0, the host vehicle is identified as being nearer to the preceding vehicle and normal mode is engaged, and, when TDH is closer to 1.0, the host vehicle is farther from the preceding vehicle and sport mode is engaged. - View Dependent Claims (15, 16, 17, 18, 19)
