Car Interior and
Monitoring and Alerts
Bluetooth has become increasingly common in automotive applications in recent years. Bluetooth allows drivers to connect their smartphones or other devices to their car's audio/central control system, enabling hands-free calling, music streaming, and vehicle diagnostics.
Wireless Sensors Networks
A Bluetooth digital key allows a driver to use their smartphone as a key to unlock and start their vehicle. A digital key can be easily shared with other drivers, without the need to physically exchange keys or fobs. Additionally, a Bluetooth digital key can be programmed to provide access to specific features or settings within the vehicle, such as adjusting the seat and steering wheel to a passenger's preferred settings, making accessing and operating a vehicle more convenient, secure, and customizable.
Bluetooth sensors can be used to monitor a wide range of vehicle performance and environmental conditions, such as engine temperature, tire pressure, fuel efficiency and battery, etc. By wirelessly transmitting this data to a central control system, vehicle manufacturers can reduce the complexity of the car's wiring and improve overall reliability.
Bluetooth sensor networks can provide real-time feedback to drivers on their driving behavior and vehicle performance. For example, sensors monitoring acceleration, braking and speed, can provide feedback on how to improve fuel efficiency and reduce emissions.
BLE + UWB + NFC
Cabin Vital Monitoring Systems
The combination of BLE, UWB and NFC is the best solution for digital keys. Bluetooth is extremely low power, it is used to wake up UWB and encrypt data transmission. UWB is for precise positioning and secure ranging which can prevent relay attacks and radio signals from being intercepted or interfered. NFC enables access when the phone is out of power.
UWB sensors can work through clothing and other obstacles, offering a less intrusive and more user-friendly solution. One of the applications is to track the vital signs of passengers in the car, such as heart rate and respiration rate. This information could then be used to provide real-time feedback to the driver or to emergency services in the event of a medical emergency.
UWB technology can also be used to monitor and detect the presence of occupants in the car. The data could be applied for enhancing safety features, such as automatic seat belt tightening or airbag deployment, and alert drivers if children or pets have been left in the vehicle accidentally.
