Sensors in the Automotive Industry
Sensors play an important role within the automotive industry, providing on-board management systems with essential information.
Cars today require a variety of sensors to monitor elements such as engine speed, tyre pressure, air temperature and more. As being able to respond to changing conditions, by monitoring and responding to data is a must. A standard on board diagnostic interface on most modern-day automotive vehicles will now normally contain more than 50 individual sensors.
This has been largely driven by increased demands on safety, comfort, reliability, energy efficiency and reducing environmental impact. All key areas that are becoming more important in modern day cars, as more demanding requirements are placed upon the machines. As a result sensor technology has become an integral part of automotive vehicle design and manufacturing. We are committed to improving the safety of vehicles and helping to make them more energy efficient and environmentally friendly.
Semefab’s automotive sensors are produced to exacting specifications, providing essential data used within a number of automotive vehicles. Allowing on-board systems to identify and respond to changing conditions both inside and out.
We also provide sensors for tier 2 and tier 3 suppliers to the automotive sector. These are regularly designed and manufactured to exacting specifications, often on a custom basis. As we have the experience and capacity to optimize and adapt sensors to meet individual requirements and markets.
Common Automotive Sensors
Some common sensors that can be found in most automotive vehicles.
- Fuel tank pressure sensors that monitor evaporative emissions and detect leaks.
- Gas sensors which ensure that only clean air can permeate the passenger compartment.
- ASICs that control speed dependent windscreen wiper rates and window lift controls.
- Electrochromic rear-view mirror dimming chips which make night time driving less stressful.
- Strain gauges that inform air bag deployment and ensure seat belts get fastened securely.
- Speed sensors used in Anti-lock Brake Systems (ABS) that monitor the wheel speed, helping to prevent wheels from locking up.
- Intake air temperature sensors monitor the temperature of the air entering the engine and help to regulate the air/fuel ratio.
- Position sensors are used to monitor the rotational speed of the crankshaft to control the fuel mixture and spark advance.
- Mass air flow (MAF) sensors are used to monitor the density and volume of air that enters the engine.
