Sensor fusion is a key technology in ADAS (FCW, PCW, AEB, ACC, etc.) In this paper, the target-level fusion method is used to realize the recognition of key targets through the algorithms such as estimation of the driving area, screening for effective targets, targets matching, target fusion and target tracking. Simulation test and real vehicle test show that the algorithms can identify key targets steadily and screen out radar jamming targets such as guardrails and viaducts.

A low-cost and intelligent power supply system with an STC15 single-chip microcomputer as the main controller is designed. The single chip monitors the mains voltage and controls the relay to switch between the mains and battery power supply. Battery constant current, constant voltage, and floating charge intelligent charging management are achieved through the battery voltage execution. Through the ESP8266WIFI module networking, we can access weather information, and weather judgment, and choose whether to enter the battery mode, which can better protect the power system. The experimental results show that the system can operate reliably and complete the switch between mains supply mode and battery supply mode quickly.

With the continuous development of new energy technology, the photovoltaic system plays an extremely important role in people’s production and life, and new energy. As an indispensable part of a photovoltaic system, the battery voltage monitoring circuit plays a very important role. The voltage of the photovoltaic battery pack is usually relatively high. To ensure the safety of users and ensure that the controller is not affected by other adverse factors, this paper designs a voltage sampling circuit based on a high-precision linear optocoupler HCNR201. The detection circuit has strong electrical isolation characteristics and can monitor the voltage of two or more battery groups. In this paper, two groups of battery voltage monitoring using simulation and hardware test results proved that the voltage detection method has good linearity, and high accuracy, while the input and output of electrical isolation ensure user safety.
