Design, ergonomics and haptic feedback are features critical to the development of an eye-catching automobile gearshift. Manufacturers have to design and test a large number of prototypes, with different transmissions, dynamics, etc., before an appealing and marketable solution can be found. This paper introduces a haptic interface for automobile gearshift design and benchmark. It allows automo...

The diagnostic algorithm introduced by Wayland et al. to test for degrees of visible determinism in complex dynamical behavior is applied to precise estimation of noise level for the gear-noise sound emanated from automobile automatic transmissions. It is shown that the method successfully captures such a small difference in acoustical characteristics indicating micro mechanical flaws on the ge...

Model Checking is well established as a veriication technique for nite-state systems. Several important types of systems, such as protocols parameterized by the number of processes, are however inherently innnite-state, hence Model Checking cannot be applied directly to determine correctness of the system. We present here a case study on the veriication of such a parameterized protocol, the SAE...

Gear-position-decision (GPD) tactics strongly affect the performances of automatic transmissions (AT) and, therefore, the performance of the vehicle. Since the electronic control methods were introduced into ATs, many advanced techniques have been raised tomakeAT vehiclesmore human friendly and better in fuel economy and dynamic behaviors. As a type of emerging AT, the automated manual transmis...
