Sensors are use in detecting, measuring or recording physical phenomena and subsequently responding by transmitting information, initiating changes or effecting system control. Automotive sensors is integrated part of vehicle system and is designed to detect, transmit, analyze and display vehicle performance information within internal and external environment of the vehicle.
Sensors have a widespread use in all type of automobiles right from two wheelers to heavy duty lorries. Some of the most common automotive application of sensors is found in wipers, lighting, dashboard, rain sensors, sunroof, parking, seat, climate, tilt alarm, tail gate release, tailgate close, trailer management, rear door, anti theft alarm, immobilizer and radio. With increasing popularities of vehicle automation and demand of concept cars around the globe, most of the research and development (R&D) attention of automotive industries is towards development of advanced automotive sensors such as MEMS (Micro-Electro-Mechanical Systems) sensors, wireless sensors and radar sensors. According to BMW (Germany based automobile company), 90% of the future car innovation will be focused on the advanced and efficient use of electronics in automotive., It is also evident in most recent development of automotive sensors technology such as “pre-emptive technology” and “Conti APIA” (integrated stability, collision avoidance, occupant protection). Sensors in automotive application such as emission control, battery control and occupant detection is witnessing escalating growth in recent years.
Based on the application automotive sensors can be broadly categorised under powertrain vehicle security system, body electronics, safety and control, telematics and others. On the basis of technology the automotive sensors are broadly categorized as temperature sensors, pressure sensors, level/position sensors, NOX sensor, speed sensors, MEMS sensors, magnetic sensors, oxygen sensor, inertial sensors and others.
The automotive sensors are one of the fasted growing sectors in automotive industry with growth rate in double digit, especially in OEM (original equipment manufacturing) section. North America remains the largest market for automotive sensors market, followed by Europe and Asia Pacific. Germany leads the European market and China and Japan leads the Asia Pacific market. The growth is expected to be highest in Asia Pacific mainly attributed to growing economy of some of the other Asia Pacific’s nations such as India, Indonesia, Malaysia, Thailand and Philippines.
The continuous development in electronics sensors application and technology, the rising concern for safety, increasing demand of automation in automobiles, demand of concept cars from high income consumers and increasing use of sensors in hybrid semi hybrid and electric cars are boosting the demand of automotive sensors market. Lack of aftermarket for sensors is one of the chief restraints in the developing market of automotive sensors.
Development in the field of ’Advance Driver Assistance Systems‘(ADAS) and hybrid and electric vehicle are showing promising the future opportunities for automotive sensors market.
Some of the major players operating in the automotive sensors market include Analog Devices, Inc., ATI Industrial Automation, Denso Corporation, Robert Bosch, Gmbh, Sensata Technologies, Inc., Asahi Kasei Corporation, Freescale Semiconductor, Inc, Maxim Integrated, Infineon Technologies AG, Measurement Specialties, Tekscan, Inc., Texas Instruments Incorporated and GE Measurement and Control Solutions.
