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.
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
With the series of recall campaigns, Audi made several modifications; the first adjusted the distance between the brake and accelerator pedal on automatic-transmission models. Later repairs, of 250,000 cars dating back to 1978, added a device requiring the driver to press the brake pedal before shifting out of park. [ 39 ]
A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
Honda continued on with those three models, type C, S and R, changing only the paintwork in 2006 and 2007. Honda dropped the spoked-wheel VTX1300S in 2008, but maintained lineup at three models by adding the VTX1300T Tourer variant (with cast wheels). The Tourer was basically a type R bike equipped at the factory with what had been the three ...
Whereas ABS reduces hydraulic pressure during braking, ESC may increase pressure in certain situations, and an active vacuum brake booster unit may be utilised in addition to the hydraulic pump to meet these demanding pressure gradients. At the centre of the ESC system is the electronic control unit (ECU), which contains various control ...
On a motorcycle, an anti-lock brake system prevents the wheels of a motorcycle from locking during braking situations. Based on information from wheel speed sensors the ABS unit adjusts the pressure of the brake fluid in order to keep traction during deceleration to avoid accidents. Motorcycle ABS helps the rider to maintain stability during ...
The parking pawl locks the transmission's output shaft to the transmission casing by engaging a pawl (a pin) that engages in a notched wheel on the shaft, stopping it (and thus the driven wheels) from rotating. The main components of a parking pawl mechanism are the parking gear, parking pawl, actuator rod, cam collar, cam plate, pivot pin, and ...
