The Chinese auto industry continues to sit firmly on the "throne" of global auto production and sales, but it is followed by a series of social problems: the internationally recognized safety warning line for crude oil's external dependence of more than 50%; automobile exhaust accounts for more than urban exhaust 65%… .. New energy vehicles provide the best opportunity for global solutions to the environmental and energy problems caused by traditional energy vehicles, and have become a hot spot for global attention. At the China (Chongqing) Automotive Electronics Summit held recently, electronic design based on new energy vehicles has also become a hot topic.
"In fact, apart from the different driving methods, there is no essential difference between new energy vehicles and traditional cars. A better driving and riding experience and higher safety are still the main challenges of automotive design." Fujitsu Semiconductor (Shanghai) Co., Ltd. Marketing director Wang Yu pointed out, "In terms of comfort and safety, video technology has been more and more widely used, and as the core component of new energy vehicles, high-efficiency and high-performance control technology is to achieve comfort and safety. Important guarantee. "At this forum, Fujitsu showed Chinese automotive electronics manufacturers and vehicle manufacturers the leading automotive electronic system solutions to solve the design challenges of new energy vehicles.
Motor control is the key to new energy vehicles
The concept of frequency conversion has become an absolute hotspot in home appliances including air conditioners, washing machines, refrigerators, etc. in recent years, the key of which is motor control technology. As the core component of new energy vehicles, electric vehicle motor control requirements are higher-the smooth operation of the motor, rapid start and braking, and the efficiency of the motor are all related to the key technologies of motor control, which will directly affect the energy utilization efficiency and Car performance, driving experience and vehicle safety.
As a major global supplier of traditional consumer and industrial motor control solutions, Fujitsu is also at the forefront of motor control for new energy vehicles, and its 32-bit motor control MCU MB91F267NA has achieved many successful applications. A few days ago, Fujitsu once again released three models of electric vehicle motor control MCU MB91580 for the unique needs of new energy vehicles for motor control. As a member of the FR family of high-performance 32-bit flash memory embedded microcontrollers (MCU), this series of products can be widely used in motor control of electric vehicles and hybrid vehicles. This series of energy-saving car drive motor control chips have a dedicated embedded resolver sensor interface, which can pioneer the control of three-phase motors used in electric vehicles and hybrid vehicles.
