2. Brake-by-wire - Wikipedia

   en.wikipedia.org/wiki/Brake-by-wire

   The hydraulic force generated by pressing the brake pedal is used only as a sensor input to the computer unless a catastrophic failure occurs including a loss of 12-volt electrical power. The brake actuator has an electric pump that provides the hydraulic pressure for the system, and valves to pressurize each wheel caliper to apply the friction ...

3. Vector control (motor) - Wikipedia

   en.wikipedia.org/wiki/Vector_control_(motor)

   In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...

4. Servo (radio control) - Wikipedia

   en.wikipedia.org/wiki/Servo_(radio_control)

   The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.

5. Motor controller - Wikipedia

   en.wikipedia.org/wiki/Motor_controller

   A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...

6. Actuator - Wikipedia

   en.wikipedia.org/wiki/Actuator

   An actuator is a component of a machine that produces force, torque, or displacement, when an electrical, pneumatic or hydraulic input is supplied to it in a system (called an actuating system). The effect is usually produced in a controlled way. [1] An actuator translates such an input signal into the required form of mechanical energy.

7. Electronic control unit - Wikipedia

   en.wikipedia.org/wiki/Electronic_control_unit

   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.
