Introduction to Highly Automated Vehicles

2018-07-23
Every year, the U.S. experiences more than 32,000 traffic deaths and over 3.8 million crash injuries. While the trend in traffic deaths has been downward for the past decade, most of this reduction has been the result of optimizing passive occupant crash protection systems such as seatbelts and airbags. Advanced driver assistance systems (ADAS) now offer the potential to significantly reduce or eliminate most vehicle crashes by perceiving a dangerous situation before the crash has occurred and taking action to avoid or mitigate the crash.

Development of Variable Cylinder Management System for Large Motorcycles

2009-04-20
2009-01-1044
The world’s first variable cylinder management system, VCM system, for large motorcycles has been developed. The system uses an in-line four-cylinder, 1 137 cm3 engine as the base, and allows changing of the number of working cylinders from 2-cylinder to 3-cylinder to 4-cylinder. To eliminate an abrupt change of power delivery when shifting number of working cylinders, the electronically-controlled throttle valve (Throttle-By-Wire: TBW) is employed. Coupled with the harmonized control of the intake-and-exhaust valve deactivating system, the smooth switching of number of working cylinders suitable for motorcycles has been realized. As a result, while maintaining the same power output characteristics of the conventional engine, EURO 3 exhaust emission regulations are satisfied while attaining approximately 46% better fuel economy in the New European Driving Cycle mode (NEDC mode).

Research of Electronically Controlled Throttle System for Large Motorcycles

2009-04-20
2009-01-1047
There are various demands concerning the motorcycle rider’s throttle input such as nonlinearly engine output attribute control and maximum speed control. To realize those demands by electronic control, we mounted the Drive-by-Wire (DBW) throttle system, which is currently being used on existing automobiles, to motorcycles, but the system failed to meet the demands of the motorcycle. Response to the throttle speed change was an issue; therefore, we built up the control system to satisfy the motorcycle’s demand for response by changing the high speed response equation of adaptive sliding mode control and adding the hysteresis property correction equation of the throttle body drive-train. As a result, we could realize response equivalent to that of a mechanical throttle.
