Lighting in an automobile is considered to be an important system as it is crucial for safety, convenience, and comfort as well as styling in modern vehicles. It includes lighting and signaling devices located on front, sides, and rear of a vehicle. The primary use of automotive lighting is to ensure visibility to the driver, improve vehicle conspicuity, and intimate the presence and position of the vehicle to others.

An automotive catalytic converter is a device that is placed inside the tailpipe of a vehicle. The device controls the amount of toxic pollutants being released from the exhaust pipe. It consists of precious metals (platinum and palladium) that catalyze (accelerate the rate of) redox reaction (an oxidation and a reduction reaction) that converts harmful exhaust gases to less toxic gases.

On-board diagnostics (OBD) system gathers diagnostic information from various subsystems in a vehicle. The information is gathered by physically connecting a diagnostic tool to the built-in OBD port of the vehicle. OBD system was initially designed to diagnose and curb emissions by monitoring the performance of engine components. While the initial version of OBD just displayed an indicator light on the dashboard in the case of a malfunction of a subsystem, subsequent advances have helped to establish a standardized communication port and a set of diagnostic troubleshooting codes.

An automotive automatic transmission (AT) system allows the gears to be automatically changed, without the need for pressing the clutch manually. This type of transmission system is also known as self-shifting transmission or n-speed transmission and provides a wide range of speed and torque output. A vehicle equipped with AT comes equipped with automatic gearboxes, which are devoid of the conventional clutch pedal.

Any vehicle that has a three- or five-door construction with a rear opening can be referred to as a hatchback. Hatchbacks can be identified by their rear structure, which may either be almost vertical or curved. The design character includes the boot within the main structure (integrated) with no visible extrusion.

Automotive is an ever-evolving domain with the adoption of aesthetics as well as new and advanced technologies propelling the dynamicity of the industry. The trend of owning a vehicle that is stylish, safe, and comfortable is rapidly growing. Owing to the highly competitive scenario in the industry, OEMs are aiming to boost the visual appeal of vehicles by adopting higher aesthetic approaches. The practice of restricting premium interiors to the luxury vehicle segment has changed. Currently, even economical and mid-sized vehicles are coming up with premium interior features to attract end-users. The advances in cost-effective technologies coupled with the global availability of suppliers with low-cost products and raw materials are further pushing the adoption of premium interior features in all vehicle segments.

An automotive steering system acts as a direct line of control and communication between the driver and the vehicle. Automotive steering systems have evolved from being rigid mechanisms to more technologically advanced, smooth, reliable, and easyto- use systems. Modern automotive steering systems are equipped with advanced safety systems and advanced driver assistance systems (ADASs), such as airbags (in steering wheels), and controls for anti-lock braking system (ABS), adaptive cruise control (ACC), and passenger airbag systems (PAS) to ensure safe and smooth driving and to provide improved directional stability and agility to the vehicle.

过低或过高温度均会影响锂电池性能和使用寿命，因而必须拥有热管理系统。根据传热介质的不同，电池热管理系统可分为风冷、直冷与液冷，液冷相对直冷成本更低，冷却效果也优于风冷，具备主流应用趋势。
