Latest Patents

Reed's work includes several noteworthy patents, reflecting his commitment to advancing technology in the automotive industry. His latest innovations are:

1. **Real Time Suspension Control with Digital All-Pass, High-Pass Filter**

This patent describes a vehicle suspension control system that utilizes an absolute vertical acceleration sensor mounted on the vehicle body to integrate and provide a vertical velocity signal. The system features a high-pass filter designed to remove DC components, allowing only components in the frequency range of 1-2 Hz to pass through. The patented filter is characterized by a second-order digital all-pass filter implemented recursively on a 16-bit fixed-point digital signal processor (DSP). This innovative approach employs a normalized lattice two-pair network to achieve a unity gain stage while minimizing computational time through a second-stage single multiplier lattice network.

2. **Full Vehicle Suspension Control with Non-Vertical Acceleration Correction**

In this patent, Reed presents a comprehensive vehicle suspension control system for wheeled vehicles, utilizing suspension actuators and absolute accelerometers at each corner. These actuators operate in response to vehicle body pitch and roll velocity signals derived from nominally vertical acceleration inputs. The process includes deriving and integrating pitch and roll acceleration signals to mitigate any non-vertical errors, ultimately reducing saturation of the integrator and enhancing vehicle stability and performance.
