National Instruments: With the Electrification of vehicles companies like Tesla having achieved huge success in the Electric Vehicle Market, people are looking towards more and more electric vehicles. Similarly there is a huge focus on Advanced Driver Assistance System or ADAS. ADAS has a very wide scope and can range from cameras and sensors like LIDARs and ultrasonic proximity sensors providing the driver parking assistance to a lot more. A lot of companies right now are focusing on having Automotive Radars working in the high frequency bands to detect obstacles like an airplane does.
Texas Instruments: Electric Vehicles (EV) / Hybrid Electric Vehicles (HEV) are of major interest because of restrictions with fuel usage and increasing pollution. There would be good requirement of charging stations for these vehicles so as to encourage EV/HEV. With Li-Ion emerging into EV/HEV, complete battery management system with high level safety is primarily required to increase the reliability. Technologies like ultrasonic based sensors, camera based detection or RADAR based parking assist systems are likely to be installed in almost all four wheelers.
Electromagnetic Interference (EMI) compliance is an important topic for many major automotive manufacturers trying to build the newest systems for cars. Apart from these, improving user experience with systems like USB charging for 2 Wheelers, IOT cluster, LED head lamps and sensors like – Rain light sensor, soot sensor, AMT sensor, EGRT sensor, Radar etc. will be required in near future.
Analog Devices: Automotive manufacturers are focusing on passenger safety, infotainment, optimum fuel consumption and ease of drive in the entry level vehicles. This has led to entry level passenger vehicles having air bags, ABS, tyre pressure sensing, keyless entry, proximity sensing for drivers, start/stop feature and infotainment. These have almost become like a ‘must have’ primary requirements in the passenger vehicles. The 2-wheeler segments also have the start/stop feature given that there is an emphasis on optimum fuel consumption in this segment.
