Title: Innovations of Hong Xing Hu in Vehicle Control Systems

Introduction

Hong Xing Hu is a notable inventor based in Rochester Hills, MI (US), recognized for his contributions to vehicle control systems. With a total of four patents to his name, Hu has made significant advancements in automotive technology, particularly in brake control systems and sensor-responsive methods.

Latest Patents

One of Hu's latest patents is a brake control system designed for vehicles with four wheels. This innovative system involves determining a desired yaw rate and a yaw torque command based on that rate. In scenarios where the vehicle is in an anti-lock braking mode during driver-commanded braking, the system applies the yaw torque command to only one wheel, effectively releasing brake pressure in that wheel. Additionally, if the vehicle is in a positive acceleration traction control mode during driver-commanded acceleration, the system applies brake pressure to one wheel as well. Furthermore, if the vehicle is not in either of these modes, the system determines whether the brake pedal is depressed and applies brake force accordingly, creating a left-right brake torque differential responsive to the yaw torque command.

Another significant patent by Hu is a sensor-responsive control method and apparatus for motor vehicles. This method includes measuring the vehicle's yaw rate and lateral acceleration, estimating the steering wheel angle based on these measurements, and determining an error signal that reflects the difference between the estimated steering wheel angle and an adaptive steering position signal. The adaptive steering position signal is then updated quickly after the vehicle begins to move, enhancing the vehicle's responsiveness and control.
