Electrification

One of the major trends in the automotive industry is the shift from internal combustion engines (ICEs) to electric vehicles (EVs), which are powered by batteries or fuel cells. EVs offer several benefits over ICEs, such as lower emissions, higher efficiency, lower maintenance costs, and better performance. However, EVs also require more semiconductors than ICEs, as they need to control the electric motor, the battery management system, the power conversion system, and the charging system. According to a report by Mordor Intelligence, EVs use about three times more semiconductors than ICEs on average.

Some of the key semiconductor technologies and applications that enable electrification in vehicles are:

  • Silicon carbide (SiC) and gallium nitride (GaN) power devices: These are advanced materials that can handle higher voltages, currents, temperatures, and frequencies than conventional silicon power devices. They can improve the efficiency and reliability of power conversion systems in EVs and reduce the size and weight of components.
  • Battery management system (BMS) chips: These are integrated circuits that monitor and regulate the voltage, current, temperature, and state of charge of each battery cell in an EV. They can optimize the performance and lifespan of the battery pack and prevent overcharging or overheating.
  • Wireless charging chips: These are integrated circuits that enable wireless power transfer between a charging pad and an EV. They can eliminate the need for cables and plugs and provide convenience and safety for EV users.

Automation

Another major trend in the automotive industry is the development of autonomous vehicles (AVs), which can drive themselves without human intervention. AVs have the potential to improve road safety, reduce traffic congestion, enhance mobility, and create new business models. However, AVs also require more semiconductors than conventional vehicles, as they need to process large amounts of data from various sensors, cameras, radars, lidars, and mapsAccording to a report by Statista, AVs use about ten times more semiconductors than conventional vehicles on average.

Some of the key semiconductor technologies and applications that enable automation in vehicles are:

  • Artificial intelligence (AI) chips: These are processors that can perform complex calculations and machine learning tasks at high speed and low power consumption. They can enable AVs to perceive their surroundings, plan their routes, make decisions, and communicate with other vehicles and infrastructure.
  • Advanced driver assistance systems (ADAS) chips: These are integrated circuits that support various functions such as adaptive cruise control, lane keeping assist, blind spot detection, collision avoidance, parking assist, and driver monitoring. They can enhance the safety and comfort of drivers and passengers and pave the way for higher levels of automation.
  • 3D mapping chips: These are integrated circuits that can create high-resolution 3D maps of the environment using data from lidars or cameras. They can provide accurate localization and navigation for AVs and enable them to cope with dynamic scenarios.

Connectivity

A third major trend in the automotive industry is the integration of connectivity features in vehicles, which allow them to communicate with other devices such as smartphones, tablets, laptops, smartwatches, or smart home appliances. Connectivity features can enhance the user experience, provide entertainment and information services, enable remote diagnostics and updates, and support new business models such as car sharing or ride-hailing. However, connectivity features also require more semiconductors than traditional features, as they need to support various wireless standards such as Bluetooth, Wi-Fi, cellular, and satellite.

Some of the key semiconductor technologies and applications that enable connectivity in vehicles are:

  • Infotainment system chips: These are integrated circuits that control the display, audio, video, navigation, and voice recognition functions in a vehicle’s infotainment system. They can provide various services such as music, navigation, voice control, and smartphone integration. They can also support over-the-air updates and remote diagnostics for vehicles.
  • Vehicle-to-everything (V2X) chips: These are integrated circuits that enable vehicles to communicate with other vehicles, infrastructure, pedestrians, devices, networks, and clouds using wireless standards such as DSRC or C-V2X. They can improve road safety, traffic efficiency, energy savings, and mass surveillance.

Safety

A fourth major trend in the automotive industry is the improvement of safety features in vehicles, which aim to protect the occupants and other road users from accidents and injuries. Safety features can be classified into two categories: passive safety and active safety. Passive safety features are designed to minimize the impact of a crash, such as airbags, seat belts, and crumple zones. Active safety features are designed to prevent or mitigate a crash, such as an anti-lock braking system (ABS), electronic stability control (ESC), and automatic emergency braking (AEB). However, safety features also require more semiconductors than traditional features, as they need to sense, process, and actuate various signals and commands.

Some of the key semiconductor technologies and applications that enable safety in vehicles are:

  • Sensor chips: These are integrated circuits that can measure physical parameters such as pressure, temperature, acceleration, speed, distance, angle, or light. They can provide input for various safety functions such as airbag deployment, tire pressure monitoring, seat occupancy detection, or adaptive lighting.
