An ECU from a Geo Storm. 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.
Vehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion.
It may also provide in-vehicle connectivity via Wifi and Bluetooth and implements the eCall function when applicable. In the automotive domain, a TCU can also be a transmission control unit. A TCU consists of: A satellite navigation (GNSS) unit, which keeps track of the latitude and longitude values of the vehicle
When one of these errors occurs, usually it will turn on the "check engine" light on the dashboard. The PCM is one of potentially several on-board computers, or essentially the "brain" of the engine control system. [1] The primary inputs to the PCM come from many sensors, of different types, that are spread around the car.
Such systems are used for many internal combustion engines in other applications. In aeronautical applications, the systems are known as " FADECs " (Full Authority Digital Engine Controls). This kind of electronic control is less common in piston-engined light fixed-wing aircraft and helicopters than in automobiles.
Also gas pedal. A throttle in the form of a foot-operated pedal, or sometimes a hand-operated lever or paddle, by which the flow of fuel to the engine (and thereby the engine speed) is controlled, with depression of the pedal causing the vehicle to accelerate. admission stroke See induction stroke. aftermarket air brake 1. A type of brake in which the force that actuates the brake mechanism is ...
When a vehicle detects a problem, it generates a DTC code which is a unique code that corresponds to the specific problem detected. The code is usually a combination of letters and numbers. DTC codes are read by a diagnostic tool, such as an OBD 2 scanner, which is plugged into the vehicle's diagnostic port. The tool communicates with the ...
