Market Dynamics

Market Drivers

Rapid Development in Automotive Industry along with Demand for Safety Features Drives the Market

The microcontroller used in the automotive industry is utilized in several systems such as fail-safe systems, electric control units, automotive fault-tolerant systems, and others. The fault-tolerant system senses any fault in the vehicle or any incident to be occurred by the vehicle with the help of a sensor microcontroller and engages the required function for that instance.

According to the Department of Transportation of the U.S., nearly 32 fatalities occur every day in the U.S. in drunk and driving car crashes, which is one fatality every 45 minutes.

As per the annual traffic crash data released by the Department of Transportation National Highway Traffic Safety Administration (U.S.), in 2022, nearly 42,795 lives were lost in traffic crashes across the U.S.

Therefore, due to the increase in road accidents worldwide, the demand for safety features such as parking assistance, lane departure warnings, collision avoidance systems, electronic stability control, airbags, telematics, traction control, blind spot detection system, and adaptive cruise control is driving the market.

Rising Government Regulations on Emission Reduction Drives the Market

Microcontrollers are widely used in powertrain applications to minimize vehicle emissions and improve engine efficiency. Moreover, these aid in reducing fuel consumption. In April 2019, the European Union adopted regulation 2019/631 to reduce CO2 emissions from passenger and light commercial vehicles.

This regulation specifies fleet-wise emission standards for the next decade. Specific standards for cars and vans are set under this regulation for 2020 – 2024. If a manufacturer fails to maintain these targets, then a penalty will be levied for each of its vehicles newly registered in that year.

Microcontrollers play a pivotal role in emission control technology and help minimize CO2 emissions by enabling efficient engine control. Such government initiatives and technological advancements will drive the sales of microcontrollers in the automotive industry.

Market Restraint

Functioning and Operational Failures in Extreme Weather Conditions Hamper Market Growth

An automotive microcontroller unit that faces failure issues leads to a complete shutdown of the vehicle’s operation. Microcontroller has a very low tolerance to a temperature, such as in extreme cold and hot environments, which causes impairment in its functions and results in operations failures.

In extremely hot temperatures, the microcontroller tends to melt down, breaking the resistance and weakening signals, due to which failure occurs. Moreover, the microcontroller also stops working in extremely low temperatures.

Due to this issue, countries that experience extreme weather conditions tend to use the least number of microcontrollers required in the vehicle, majorly restraining the market.

Although to tackle this situation, various companies are focused on developing microcontrollers, such as high-temperature and low-temperature microcontrollers, that will sustain the temperature variations according to the region.

STMicrocontroller introduced the SPC5 family of 32-bit automotive controllers designed to operate for various applications, including ADAS to engine and transmission control, safety features, and others. The SPC5 microcontroller offers up to three cores and can operate at a temperature range of -4000C to 1,6500C temperature.
