Throttle body with integrated motor actuator. Electronic throttle control (ETC) is an automotive technology that uses electronics to replace the traditional mechanical linkages between the driver's input such as a foot pedal to the vehicle's throttle mechanism which regulates speed or acceleration.
Electro-magnetic actuators are usually located on the fuel pump to transfer electrical signals into mechanical action in this case fuel rack actuator and or fuel stop solenoid which means that depending on requests from control unit full fuel or no fuel quantity. Injectors; Boost-pressure actuator; Intake-duct switchoff; Throttle-valve actuator
Accelerate-by-wire or throttle-by-wire, [17] more commonly known as electronic throttle control, is a system that actuates vehicle propulsion without any mechanical connections, such as cables, from the accelerator pedal to the throttle valve of the engine or other propulsion systems. In electric vehicles, this system controls the electric ...
These electronic systems typically work in conjunction with the engine control unit (in a similar way to road cars), and are responsible for operating electronic throttle control, clutch and gearshift actuation (via an electric, hydraulic, or pneumatic actuator), gearshift time and speed, sensors, switches, solenoids, and other hydraulic ...
The Ford EEC (Electronic Engine Control) system, which utilized the Toshiba TLCS-12 microprocessor, went into mass production in 1975. [ 7 ] The first Bosch engine management system was the Motronic 1.0 , which was introduced in the 1979 BMW 7 Series (E23) [ 8 ] This system was based on the existing Bosch Jetronic fuel injection system, to ...
Some engine control units (ECUs) also control the throttle position by electronic throttle control (ETC) or "drive by wire" systems, and if that is done, the position sensor is used in a feedback loop to enable that control. [1] Related to the TPS are accelerator pedal sensors, which often include a wide open throttle (WOT) sensor.
The electronic control unit powers an actuator, which engages and disengages the clutch in a smooth manner. In some cases, the clutch is actuated by a servomotor coupled to a gear arrangement for a linear actuator, which, via a hydraulic cylinder filled with hydraulic fluid from the braking system, disengages the clutch.
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.
