Title: Innovations of Alexander J MacDonald

Introduction

Alexander J MacDonald is a notable inventor based in West Bloomfield, MI (US). He has made significant contributions to the field of vehicle dynamics, holding a total of 5 patents. His work focuses on enhancing vehicle control systems, particularly in relation to driver skill levels and vehicle handling.

Latest Patents

One of his latest patents is titled "Vehicle dynamics actuator control systems and methods." This invention includes a vehicle control system that utilizes a first error module to determine a first yaw error based on the difference between the vehicle's yaw rate and a target yaw rate. Additionally, a second error module calculates a second yaw error based on the first yaw error and a target yaw error. The system also features a target yaw error module that adjusts the target yaw error according to the driver's skill level. An adjustment module selectively increases or decreases a target adjustment when the second yaw error exceeds a predetermined threshold. Finally, an actuator control module actuates a dynamics actuator of the vehicle in response to the adjustments made.

Another significant patent is "Systems and methods for classifying driver skill level and handling type." This invention includes a skill level module that assesses a driver's skill based on both lateral and longitudinal acceleration of the vehicle. A handling module determines the handling type based on the rate of change of the steering wheel angle. The actuator control module then selectively actuates a dynamics actuator based on the driver's skill level and handling type.
