With a total of 2 patents, Estep has made significant advancements in the automotive field, particularly in methods that enhance the accuracy of vehicle speed signals.
Latest Patents
Estep's latest patents include a "Method of calibrating vehicle speed signals" and a "Speed/rpm transmitting device." The method of calibrating vehicle speed signals involves determining a calibration factor by driving a vehicle over a measured distance, counting the generated pulses, and calculating the calibration factor based on the pulse count and a nominal pulse count stored in memory. This innovation allows vehicle operators to see the difference in reference speed using both old and new calibration factors, enabling them to accept or abort the new calibration factor. The speed/rpm transmitting device utilizes a microcontroller with two internal timers to calibrate engine RPM and wheel speed signals, which are then transmitted to digital RPM and speed indicators.
