2. Engine braking - Wikipedia

   en.wikipedia.org/wiki/Engine_braking

   In hybrid electric vehicles, like the Toyota Prius, engine braking is simulated by the computer software to match the feel of a traditional automatic transmission. For long downhill runs, the "B" mode acts like a lower gear, using the higher RPM of the internal combustion engine to waste energy, preventing the battery from being overcharged. [ 5 ]

3. Manumatic - Wikipedia

   en.wikipedia.org/wiki/Manumatic

   This was provided to allow engine braking on downhills or prevent the use of overdrive gears when towing and was typically achieved using positions such as "3", "2", and "1" on the gear selector. An automatic transmission with a manumatic function provides a greater level of control by allowing the driver to request an upshift or downshift at a ...

   en.wikipedia.org/wiki/Automatic_transmission

   This unit was an early semi-automatic transmission, based on the design of a conventional manual transmission, which used a servo-controlled vacuum-operated clutch system, with three different gear shifting modes, at the touch of a button; manual shifting and manual clutch operation (fully manual), manual shifting with automated clutch ...

   Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...

   Even though automatic emergency braking, or AEB, is already common on new vehicles sold in the US, these new requirements will save hundreds of lives per year, NHTSA officials said in a statement.

   Pawl transmission brake, inside an automatic transmission. A form of transmission brake is commonly fitted to automatic transmissions. These brakes use a dog clutch or pawl system, rather than friction linings. They thus provide a simple and positive lock when stationary, but cannot (or at least, should not) be engaged when moving.
