The data shows that the market size of MEMS components will reach 8 billion US dollars in 2014, with a growth rate of about 14%. One of the important sources of growth is the automotive electronics field, which is mainly used in automotive safety.
With the continuous advancement of automotive technology, electronic products such as sensors continue to be applied to the automotive industry and play a vital role in the automotive field. It has been reported that the microelectromechanical systems (MEMS) sensor market is gradually recovering after a five-year recession in the past, and a large part of its recovery is driven by the development of new-generation devices and new applications.
MEMS sensor boom caused by puncture hidden danger
The reason why MEMS sensors can achieve a major reversal in the automotive field is due to the car tires. In August 2000, Bridgestone announced the recall of 6.5 million tires assembled on Ford-produced SUVs due to a puncture, which prompted the US government to legislate for mandatory requirements since September 2007. A tire pressure monitoring system (TPMS) is required for every light vehicle that is shipped from the factory. In addition, the United States also announced that by 2012 all new vehicles must use anti-rollover "electronic stability control technology" to reduce the number of deaths caused by vehicle rollover each year. So far, how to use MEMS sensors to effectively improve the performance of automotive safety systems has become the most concerned topic for automotive modules and vehicle manufacturers worldwide.
Car safety, eternal topic
Safety first, this is an eternal topic in the automotive industry. Automobile safety systems are generally divided into active safety systems and passive safety systems. The so-called active safety is to prevent the occurrence of accidents and determine the probability of accidents in the car. Passive safety is the protection of the car members or the protection of the vehicles or pedestrians in the event of an accident. The severity of the injury to the member.
In the era of smart cars, active safety technology has become a high-profile emerging field. In general, active safety systems for vehicle body control include: car roll control, car anti-skid stability control, anti-lock braking system, parking brake, tire Systems such as pressure monitoring, suspension-to-vehicle and adaptive adjustment of road conditions, while MEMS sensors play a major role in active safety systems. Due to their small size and high reliability, these sensors can be mounted on the car frame and suspension to monitor the relative position of the car to the ground, allowing the car to adjust the suspension and suddenly turn the car, the weather is poor or the road surface Provides maximum stability when not flat.
Rollover and stability control can be said to be a new improvement to today's active safety systems, requiring MEMS accelerometers and angular velocity sensors to sense body posture. Since such sensors are often installed in locations where vibration is relatively harsh, sensors are required to have high vibration shock resistance, which is also a technical difficulty for MEMS sensors.
Smart car safety system, two new development trends
At present, one of the development trends of smart car safety systems is that the loading rate of airbags and the number of stability control (ESC) systems is rising rapidly. We know that one of the characteristics of automotive technology development is that more and more components are electronically controlled. Therefore, the number and scale of electronic systems are constantly expanding, and in particular, more MEMS sensors are needed to sense different parts of the collision and the posture of the vehicle. At the same time, the reduction of system complexity and system cost through the integration of multiple sensors is another major trend in the development of automotive safety systems.
