In order to meet growing market demand, Freescale has advanced MEMS 8-inch production line put into use in the production lines
Today, automotive safety sensors is becoming increasingly important components of the automobile manufacturing, the world's major automotive electronics giant has begun vied for the vehicle security sensor market, Infineon, Freescale, STMicroelectronics, Renesas, NXP pump, etc. semiconductor manufacturers are gearing up with a diverse product line, car security solution for these enterprises is very targeted.
Infineon in 2007 has been launched in the Asia-Pacific market tpms sensor SP35. The subsection sensor has formed the production scale, and has sold millions of copies. It integrates the wheel module is required for sensing and transmitter function, this technology enables the mcu, sensor and RF transmitter are packaged together. Compared with the SP30 and the external RF transmitter IC solution, the SP35 system solution will reduce to a component.
In order to meet growing market demand, Freescale has advanced MEMS 8-inch production line put into use in the production line to improve the product in respect of power, economic efficiency and volume indicators, so that Freescale's new MEMS The sensor can easily respond to competitive challenges. Freescale has introduced in 2007 mpmsy8300tpms This TPMS is the industry's first to contain the capacitive pressure sensor tpms work properly, no matter which tire (including the spare) is a non-optimal tire pressure, TPMS will alert the driver immediately.
NXP in the the tpms areas of product is P2SC Series signal conditioners. A senior member of the series pch7970 mainly used for signal conditioning and data framing, for the continuous monitoring of the individual tire pressure. 8 risc core with the help of the device can provide a general-purpose I / O control external circuitry, and provides 12-bit ADC to monitor the output voltage of the piezoresistive bridge sensor.
The reporter learned that the car navigation systems failure mainly to delay for voice prompts, detour, repeated U-turn instructions. The failure of car navigation systems, the analysis said Liu Zhenning, one of the reasons is due to road traffic conditions change, car navigation systems, navigation map is not updated in a timely manner. "There may be car navigation car dvd and car dvd player for car systems and shoddy products installed is pirated navigation map." Said Liu Zhenning, general, genuine navigator map than the map of piracy much more expensive, piracy navigator map can also update, but the precise is not high, there will be the map leakage painted or wrong painted.
Car navigation systems on the market price and quality problems, the reporter consulted with the City of Industry, and the quality supervision department.
No specific national standards "Now, car navigation systems in the grades and corresponding prices, so there are certain difficulties in the supervision of the navigation systems market." May 18, a law enforcement officer of the City business sector in daily work, they will check on the production of car navigation systems trademarks, packaging eligibility. Due to the current car navigation systems related to the lack of national standards, making their enforcement can not determine whether the navigator quality problems. Consumers in the purchase of the navigator, in the event of quality problems or navigation device vendors out of business, consumer repair or return will be difficult to ensure.
