VEHICLE SPEED ESTIMATING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240317234 titled 'VEHICLE SPEED ESTIMATING APPARATUS

The vehicle speed estimating apparatus described in the abstract is a system that receives various travel information from a vehicle, such as wheel speed, motor torque, and longitudinal acceleration. It then determines if wheel slip occurs, calibrates the longitudinal acceleration, and estimates the vehicle speed based on this data.

  • Vehicle information receiver gathers travel data including wheel speed, motor torque, and longitudinal acceleration.
  • Wheel slip determiner checks for wheel slip.
  • Longitudinal acceleration calibrator adjusts the received acceleration data.
  • Vehicle speed estimator calculates the vehicle speed based on the wheel speed or calibrated longitudinal acceleration.

Potential Applications: - Automotive industry for vehicle speed estimation and control systems. - Transportation sector for optimizing vehicle performance and safety measures.

Problems Solved: - Accurate estimation of vehicle speed under varying driving conditions. - Enhanced safety by detecting and addressing wheel slip promptly.

Benefits: - Improved driving experience with more precise speed estimation. - Increased safety on the road by detecting wheel slip early.

Commercial Applications: "Vehicle Speed Estimation System for Enhanced Safety and Performance in the Automotive Industry"

Questions about Vehicle Speed Estimating Apparatus: 1. How does the apparatus determine if wheel slip occurs, and why is this important? 2. What are the key advantages of calibrating the longitudinal acceleration in estimating vehicle speed accurately?


Original Abstract Submitted

a vehicle speed estimating apparatus includes a vehicle information receiver configured to receive travel information of a vehicle including a wheel speed, a motor torque, and a longitudinal acceleration of the vehicle, a wheel slip determiner configured to determine whether wheel slip occurs, a longitudinal acceleration calibrator configured to calibrate the longitudinal acceleration received from the vehicle information receiver, and a vehicle speed estimator configured for estimating, depending on a determination result of the wheel slip determiner, a vehicle speed using the wheel speed or the calibrated longitudinal acceleration.
