VEHICLE SPEED ESTIMATING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18224693 titled 'VEHICLE SPEED ESTIMATING APPARATUS
Simplified Explanation: The patent application describes a vehicle speed estimating apparatus that uses travel information such as wheel speed, motor torque, and longitudinal acceleration to estimate the speed of a vehicle.
Key Features and Innovation:
- Receives travel information including wheel speed, motor torque, and longitudinal acceleration.
- Determines if wheel slip occurs.
- Calibrates longitudinal acceleration.
- Estimates vehicle speed based on wheel speed or calibrated longitudinal acceleration.
Potential Applications: This technology can be used in various vehicle systems such as anti-lock braking systems, traction control systems, and speedometer calibration.
Problems Solved: This technology addresses the need for accurate and reliable vehicle speed estimation, especially in situations where wheel slip may affect the accuracy of traditional speed estimation methods.
Benefits:
- Improved accuracy in estimating vehicle speed.
- Enhanced safety through better control systems.
- Increased efficiency in vehicle performance.
Commercial Applications: The technology can be applied in automotive manufacturing for the development of advanced safety and performance systems, as well as in the aftermarket for vehicle speedometer calibration services.
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 potential implications of using calibrated longitudinal acceleration for estimating vehicle speed?
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.
