Different Sensors Being Used in the Automotive Industry

Sensors play a crucial part in the automobile industry, as they enable higher levels of vehicle automation and futuristic design.

Fremont, CA: The combination of onboard sensors and the internet has increased driving safety and fueled the rise of the vehicle industry. Increasing global auto sales and the introduction of new vehicle technology, such as self-driving cars, are the key factors driving growth in the automotive sensor market. Enhanced environmental regulations, advancements in safety systems such as airbags, comfort considerations, and electronic stability programs continue to increase the demand for sensors in this industry.

The sensors being utilized in the automotive industry:

Pressure and gas sensors

Pressure sensors are indispensable for measuring pressure in the common rail, oil tank, fuel tank, input manifold, braking fluid, ambient atmosphere, chassis, air conditioner compressor, tire, and adaptive suspension system. Such sensing is essential for ignition and fuel control systems as well. In addition to measuring the oxygen concentration in exhaust gases, gas sensors are also employed to measure the concentrations of hydrogen, nitrogen monoxide, and carbon monoxide. For instance, an oxygen concentration sensor in the emission control system can regulate the amount of polluting gas present or discharged.

Position and speed automotive sensors

Position sensors are vital components designed to measure the throttle angle of engines, check the level of fuel, track the steering wheel angle, measure the pedal position of brakes and accelerometer, select the gear position, and record clutch position, measure seat position, and monitor motor position. When selecting a good position sensor, it is essential to evaluate its measurement range, time response, working condition, accuracy, cost, weight, and size. Automotive speed sensors monitor the engine, crankshaft, wheel, and camshaft speeds for electronically controlled gear shifting and input/output transmission management. The most recent intelligent sensors are also the hottest new components for traction control systems, vehicle stability, and antilock braking systems.

Torque and viscosity sensors

Torque sensors are in more demand than ever before on the automotive market, as torque measurement is essential for improving the fuel efficiency of electric power steering vehicles. These sensors are also used to test the gear and clutch boxes, detect the engine's dynamic torque, and evaluate strain. In addition, viscosity sensors are increasingly being used to quantify lubricating oil qualities and improve vehicle performance.
