A transmission control unit (TCU), also known as a transmission control module (TCM), or a gearbox control unit (GCU), is a type of automotive ECU that is used to control electronic automatic transmissions. Similar systems are used in conjunction with various semi-automatic transmissions, purely for clutch automation and actuation.
A defect detector is a device used on railroads to detect axle and signal problems in passing trains. The detectors are normally integrated into the tracks and often include sensors to detect several different kinds of problems that could occur.
There are also problems with the valve block and solenoids [citation needed] When this failure starts to occur, shift quality and speed, torque transfer and even loss of ability to engage gears can occur. These problems led Volkswagen Group to extend the warranty on all of their vehicles equipped with this transmission to 100,000 miles or 10 years.
An early prototype iDrive (called the Intuitive Interaction Concept) was featured on the BMW Z9 concept in 1999. The production version debuted in September 2001 in the BMW 7 Series (E65) and was built on the VxWorks kernel [4] while the Navigation computer used Microsoft Windows CE for Automotive; [5] this can be seen when the system reboots or restarts after a software crash, displaying a ...

The Quest for the Next Breakthrough. Today, some university researchers and small pharmaceutical and supplement companies are developing treatments to curb hangover symptoms.
In practice, model uncertainties and measurement noise can complicate fault detection and isolation. [ 12 ] As a result, using fault diagnostics to meet industrial needs in a cost-effective way, and to reduce maintenance costs without requiring more investments than the cost of what is to be avoided in the first place, requires an effective ...
