Reconfigurable Vehicle Lateral Velocity Estimation

The patent divides the vehicle dynamic operating space into multiple discrete regions based on vehicle speed and yaw rate thresholds. Different mathematical models are assigned to different regions: a first model for low-speed regions and a second model for high-speed regions. This segmentation allows each model to operate within its optimal accuracy range while collectively covering all operating conditions.

The patent implements dynamic model switching based on real-time vehicle operating conditions. The system continuously monitors vehicle speed and yaw rate, and automatically transitions between different estimation models when crossing region boundaries. This dynamic adaptation ensures the most appropriate model is always used for the current operating state.

The patent segments the estimation approach by creating region-specific models that avoid heavy dependence on tire force and road surface estimations in certain operating regions. In low-speed regions where tire force estimation is less reliable, the system uses a different model formulation that is less sensitive to these parameters.

The patent applies different estimation strategies tailored to local operating conditions. Each dynamic region has its own optimized model with parameters and formulations specifically suited for that operating regime, rather than using a single universal model that must compromise across all conditions.

The patent segments the operating space into multiple regions, each with its own simplified model optimized for that specific region. This allows each model to remain computationally efficient while being accurate for its designated operating range.

The patent changes model parameters based on operating region. Different models use different parameter sets and formulations appropriate for their respective speed and yaw rate ranges, allowing each model to maintain simplicity while achieving high accuracy for its specific operating conditions.
