The automatic soft-close door is a door locking mechanism in automobiles. These systems help enable the door to be closed gently rather than banging it with significant force. In this system, the sensor mounted near the latch detects the door within half an inch and actuates a motor that pulls the door to a complete shut position. The system releases the door to prevent any injuries if the sensors detect an obstruction between the door and the latch. The different components of the system include working gear, support cantilever, electric drive, door position sensor, control unit, and a cable. This feature is crucial in terms of from safety and convenience as it ensures that the vehicle doors are shut and prevents injury to passengers that occur in the case of accidental unlatching of doors.

Mechanical keys used in vehicles have given way to high-end innovative electronic entry systems using integrated circuits that imply electromagnetic signals to lock or unlock the door. An RKE system allows vehicle entry without the need for a mechanical key, offering security and convenience. RKE systems were introduced in early 1985 in the luxury vehicle segment and gained popularity among mid-segment vehicles by 1990. Although this system took time to be adopted by end consumers, they have gained considerable traction over the years. By the mid-2000s RKE evolved into a technology that allowed drivers to lock and unlock vehicle doors with no effort, using high frequency radio signals emitted from a keyless fob, which communicates with the vehicle without the driver’s intervention. This made it possible for a driver walking toward his parked vehicle to unlock the doors just by moving within a specific range of the vehicle. This was called the passive keyless entry (PKE) system. In terms of volume sales, RKE systems dominate the automotive market as they are cheaper than PKE systems. On average, PKE systems cost $90-$150 in the aftermarket, which is five times the cost of RKE systems, priced an average of $20-$25. Although a small percentage of vehicles continue to use mechanical key systems, this is expected to reduce during the forecast period as keyless entry systems become cheaper and adoption rates increase.

A wiper system is an electromechanical component placed on the windshield of automobiles. It is used to enhance the visibility of the windshield by wiping off unwanted sand, dust, and water particles caused by harsh weather conditions such as dust storms, rain, and snow. Rain sensors are used in wiper units of vehicles for automatic wiping. Rain sensing windshield wiper technology is based on the principle of total internal reflection (TIR). The amount of light returning to the sensor depends on the amount of water on the windshield. During a downpour, the amount of light returning to the sensor decreases, thus switching on the wipers automatically; the speed is adjusted according to the heaviness of the rain.

Radar sensors (also known as headway sensors) are a key component of advanced driver assistance systems (ADASs). These sensors are employed to constantly sense (in real-time) the distance between vehicles or between the vehicle and large objects around it, thereby improving driving efficiency and safety. Automotive radar systems are usually employed in ADASs, including

A sensor is a device that detects changes in its immediate environment by picking stimulus changes and updates the system electronically. Sensors are engineered to detect chemical, physical, and process changes. A sensor sends out electronic signals, which are measured and recorded, and based on the information a corrective change is executed. There are many types of automotive sensors, such as pressure sensors, wheel speed sensors, temperature sensors, fluid level sensors, and emission sensors.

Premium audio systems deliver high-performance sound experience using a number of speakers, woofers, and other components. Automotive premium audio systems are those with surround sound, eight or more speakers, and power amplification of 400 watts and more, which offer a theater-like sound experience within the vehicle. These high-performance systems are usually part of the in-vehicle entertainment systems in luxury sedans, SUVs, and vans.

A power tailgate system is a device that aids the opening and closing a car’s tailgate or boot lid automatically. The tailgate can be opened and closed by pressing a button in the dashboard, using a remote controller, or through gestures, which are tracked by sensors placed beneath the rear bumper. The system consists of mechatronic components that are enclosed in a power assembly comprising electric latches, component carriers, and closures for opening and closing of the tailgate.

The global automotive industry is experiencing a strong growth, and the business is proving to be highly profitable. However, it faces certain challenges such as greater comfort, safety, cost-efficiency, long service life, and space-saving designs. Different types of elastomers are used to bring about thermal stability, reduced fatigue, and good deformation behavior. Automotive NVH materials reduce unwanted noise, vibrations (oscillations due to automobile mechanics), and harshness (the level of discomfort) (NVH) in automobiles. Noise in vehicles may be caused by the engine, road, brakes, exhaust system, cooling fans, and external wind noise. Automotive NVH materials perform either acoustic absorption or acoustic insulation functions to absorb the noise and prevent it from entering the inside of the vehicle, thereby enhancing the overall driving comfort.

The global automotive market is evolving rapidly with growing product portfolios, new players, increased automotive offerings, and advancements in technology. End consumers in the automotive industry have changed their mindsets and buying criteria, leading to significant shifts in the market dynamics. Consumers are becoming more aware and informed, and their expectations have grown. They consider various aspects of an automobile, including comfort, technology, safety, and style, before they finalize a purchase. Automakers, through the use of performance enhancing and boosting technologies, have been able to make their products distinctive. As automakers increasingly offer more value per car, incorporating more technologies even in lower priced car segments, consumers' buying preferences have also become more dynamic. Such a change in preference has been one of the primary reasons for the growing sales of sports utility vehicles.
