Speed and acceleration calculation and measuring methods and devices based on a regularization algorithm are disclosed. Speed and acceleration are calculated using the following steps: (1) acquiring position data or displacement data; and (2) using the position data or displacement data to calculate the speed and the acceleration with a disclosed regularization method. The disclosed methods and systems avoid the issue of noise amplification that arises when speed and acceleration are measured by existing speed and acceleration devices at high sampling rates. Noise amplification is prevented by first expressing the relationship between position data or displacement data and speed or acceleration into a typical Volterra integral equation of the first kind, and then using the disclosed regularization method to calculate speed and acceleration, thus suppressing noise amplification and accurately extracting speed and acceleration signal values.

There is provided a system for accurately assessing a person's body condition on the basis of measured values of the person's walk.

An apparatus for performing driving aid control to cause a travel trajectory of a mobile object to follow a setpoint trajectory (La) by transmitting a control command value (δ) to a yaw moment controller capable of controlling a yaw moment of the mobile object. In the apparatus, a setpoint trajectory setter is configured to set the setpoint trajectory (La) of the mobile object. A control command value calculator is configured to calculate the control command value (δ) based on an integrated value (δI) of a lateral error that is an error between a position of the mobile object and the setpoint trajectory. The control command value calculator is further configured to decrease the integrated value (δI) with decreasing a curvature (ρ) of a road on which the mobile object is traveling.
