SYSTEM FOR ESTIMATING VEHICLE VELOCITY BASED ON DATA FUSION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17824444 titled 'SYSTEM FOR ESTIMATING VEHICLE VELOCITY BASED ON DATA FUSION

Simplified Explanation

The patent application describes a system for estimating the lateral velocity and longitudinal velocity of a vehicle using multiple sensors and controllers.

• The system includes sensors that monitor data related to the vehicle's travel state.
• The controllers receive this data from the sensors and estimate an initial state of the vehicle based on it.
• The controllers then combine the data from the sensors with the initial estimated state to determine the lateral velocity and longitudinal velocity of the vehicle.
• This is done using a single state estimation scheme, which simplifies the process.
• The innovation allows for accurate estimation of the vehicle's velocity using a combination of sensor data and initial estimates.

Original Abstract Submitted

A system for estimating a lateral velocity and a longitudinal velocity of a vehicle includes a plurality of sensors for monitoring data indicative of a travel state of the vehicle and one or more controllers in electronic communication with the plurality of sensors. The one or more controllers executes instructions to receive the data indicative of the travel state of the vehicle from the plurality of sensors. The one or more controllers estimate at least one initial estimated state of the vehicle based on the data indicative of the travel state of the vehicle. The one or more controllers fuse together the data indicative of the travel state of the vehicle with the at least one initial estimated state of the vehicle to determine the lateral velocity and a longitudinal velocity of the vehicle based on a single state estimation scheme.
