Question

Question5 In steering a car, identify the sensor (measuring device), the final control element and the controller.

Answer 1

1 The Mass Air Flow Sensor

Calculates the density and the volume of the air taken in by the engine.

2 The Engine Speed Sensor

Monitors the spinning speed of the crankshaft.

3 Oxygen Sensor

Measures the amount of unburden oxygen presented in the exhaust pipe.

4 Manifold Absolute Pressure Sensor

Measures the manifold pressure inside and outside.

5 Spark Knock Sensor

Ensures that the fuel is burned correctly.

6 Fuel Temperature Sensor

Ensures the right amount of fuel is injected to keep the motion smoothly.

7 Voltage Sensor

Manages the car speed and ensures the speed is controllable.

A complete steering system is made up of more than just a steering wheel to manoeuvre the car; the system is also made up of a steering box connected to the steering wheel, the linkage that connects the steering box to the wheel assembly and a steering sensor.

Steering sensors are crucial for measuring the rotational angle of a steering wheel and communicate information on navigation. These sensors are used for automated systems that require electronic command steering (ECS) and electric power steering (EPS) systems.

Electrical power steering systems require information about the steering-wheel angle, the wheel speed, and lateral acceleration sensors to interpret the under- or over-steering of a car.

Mainly they are the form of optical, magnetic, inductive, capacitive, and resistive sensors.
