Title: Drew A Sundquist: Innovator in Vehicle Drive Systems
Introduction
Drew A Sundquist is a notable inventor based in Canton, MI (US), recognized for his contributions to automotive technology. He holds a total of 11 patents, showcasing his innovative spirit and technical expertise in vehicle systems.
Latest Patents
One of his latest inventions is the on-demand vehicle drive system. This system is designed to monitor vehicle performance and operating conditions while controlling torque delivery to the vehicle wheels. It incorporates a variety of speed and position sensors, a transfer case with primary and secondary output shafts, and a microcontroller. The sensors include a vehicle speed sensor, primary and secondary drive shaft speed sensors, as well as brake and driveline status sensors. The transfer case features a modulating electromagnetic clutch, which is controlled by the microcontroller. This clutch is incrementally engaged to transfer torque from the primary output shaft to the secondary output shaft. When the speed of either the front or rear drive shafts exceeds the speed of the other by a predetermined value, indicating wheel slip, the clutch current is increased to enhance engagement and torque transfer to the secondary axle. Conversely, when wheel slip is reduced, the current to the clutch is decreased accordingly. The method of operating such a system is also described in his patent.
