Dalianda Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that it has launched a complete solution for Toshiba and AMS automotive electronics, including tire pressure monitoring (TPMS) and automotive keyless entry systems. (RKE), Ethernet Audio Video Bridging Technology (AVB Bridge), Advanced Driver Assistance System (ADAS), Smart Rearview Mirror, and Inter-vehicle Laser Detection and Testing Technology (Lidar).
Toshiba and Austrian Microelectronics (AMS), the agents of the United Nations General Assembly, continue to develop comprehensive automotive electronics system solutions, including tire pressure detection systems, keyless entry systems, advanced driver assistance systems and Lidar. With years of experience and expertise in communications technology, we offer a complete range of in-vehicle system solutions.
Tire Pressure Monitoring System (TPMS) based on Toshiba technologyRecently, the TPMS receiver function has been integrated into a remote keyless entry (RKE) receiver, which is more prevalent in cars. As a result, a TPMS receiver must be installed within a limited range of vehicle signals that can be stably received from any direction, regardless of vehicle type and body size. Today's cars have many electronic noise sources, such as those used in electric vehicles, due to the use of electronic control systems. Therefore, an RF chip with excellent anti-interference performance will be more desirable.

Car Keyless Entry System (RKE) based on Toshiba technologyThe Remote Keyless Entry (RKE) system is designed for remote door opening and closing. When the driver presses the button on the key fob, the built-in transmitter sends out an encrypted RF signal. The onboard receiver receives the RF signal and provides the decrypted data to the microcontroller.

Advanced Driver Assistance System (ADAS) based on Toshiba technologyAdvanced Driver Assistance Systems (ADAS) is one of the smart vehicle technologies actively developed by car manufacturers in recent years. It uses single or multiple cameras to provide drivers with information on the working conditions of vehicles and changes in the environment outside the car. Analyze and warn of dangerous situations that may occur, so that drivers can take early action measures to avoid traffic accidents.

Toshiba IC can provide the following driving assistance and warnings:
Lane Departure Warning (LDW): Lane Offset Detection Warning
Traffic Sign Recognition (TSR): Identification of traffic signs
Forward Collision Warning (FCW): Warning of collision with the preceding car
Lane Change Assistance (LCA): assistance in changing lanes
Obstacle Detection: Detection of obstacles
Right/Left Turn Awareness: Reminder when turning left/right
Forward Pedestrian Collision Warning : Warning of collision with pedestrians ahead
Driver State Monitoring (DSM): Detection of fatigue driving
Parking Assistance with Bird's Eye View: Parking Assistance System
High-Beam Assistance: Detecting the car to automatically adjust the high beam assist
