CISPR25 Class5 compliant 8-rail power tree reference design for automotive ADAS/infotainment applications

This is a single channel LiDAR demo board that allows you to check the operation of a high-speed optical front end using the LiDAR ToF range technology. The measurement distance can be up to 50m. The LiDAR ToF architecture can be applied in the automotive as well as consumer and industrial machinery sectors.

Smart RV control system

The home facilities on the RV include: lighting, sofas, seats, air conditioners, TVs, stereos and other electrical appliances. It is inconvenient to set independent switches for each appliance. The smart RV control system solves such problems. The deep learning speech recognition technology of artificial intelligence technology achieved a breakthrough in 2013, and the voice interaction method will occupy an important position for a long time after the technological breakthrough. Large-size touch screens are also the development trend of vehicle-mounted human-computer interaction equipment in recent years. This system uses speech recognition and display human-machine interface (HMI) as human-computer interaction equipment, and users control electrical appliances through voice and touch screen.

Car emergency braking flashing device

In traffic accidents, rear-end collisions occur frequently due to sudden braking of the vehicle in front. Rear-end collisions are usually caused by failure to maintain a sufficient safe distance and the brakes cannot stop the vehicle. The time from when you discover an emergency ahead to when you apply the brakes is called reaction time. The length of reaction time directly affects the length of the braking distance. Especially when driving at high speed, a serious traffic accident will occur within one second. The long reaction time does not mean that the driver is slow to react, but that he does not know whether the car in front is applying the brake lightly or hard. When he finds out, two seconds have passed, and it is very likely that he will not be able to brake. If the vehicle in front The brake lights with flashing function are different. When you see the brake lights flashing, you must be stepping on the brakes harder. At this time, you should also step on the brakes harder, and the reaction time will be shortened. Therefore, in addition to letting the car behind you know whether to apply the brake lightly or hard, the flashing brake light is also particularly eye-catching and can remind the car behind you in time.

car data recorder

The automotive data logger consists of NuMicro® NUC131 microcontroller and N9H30 microprocessor. NUC131 supports CAN Bus to log On-Board Diagnostics-II (OBD-II) data, which includes vehicle speed, engine RPM, engine coolant temperature, intake air temperature, MAF air flow rate and throttle position from engine control unit (ECU) simulator. Then NUC131 converts the OBD-II raw data and transmits the above information to N9H30. N9H30 shows the received information on 7” TFT-LCD human machine interface enhanced by emWin.

electronic dog

"Electronic dog" is a vehicle-mounted device, also known as "safety warning device". Its function is to remind the car owner in advance of the existence of electronic eyes or speed radar. It allows drivers to increase their driving attention in advance where there are safety hazards, and also prevents drivers from speeding or speeding. Fines and points will be deducted for violations.

Automotive Human Machine Interface

Nuvoton has designed many highly integrated single-chip solutions that can be used as integrated parts for future automobiles. Although the cost of ISD15D00 / ISD15C00 is low, it is the best audio quality recording and playback device in its class, allowing everyday low-end cars to have audio-level sounds or voice prompts. By providing smooth communication to the SPI port of the automotive network system, system integration becomes extremely simple. ISD15D00 uses external SPI flash memory audio with built-in regulator PWM speaker driver, analog digital input and output, suitable for multi-language storage devices and audio playback of up to 64 minutes. The ISD15D00 voice macro is designed for situations where, for example, the language of the external flash memory changes but the application software does not.

Car Audio/Voice Prompt

Voice prompt warnings are components used in today's high-end luxury cars. Whether they are dashboard warnings, such as speeding, oil, water level gauges, temperature/heat, tire pressure warnings or pedestrian warning sounds for electric vehicles, they all use shared sound chips.
