SAE J1939 Sensor Array Reports Vehicle Angular Rate, Acceleration, And Attitude Data Of Heavy-Duty, Off-Highway Vehicles
Honeywell's Tars (Transportation Attitude Reference System) series of 6D inertial sensor units allows the concurrent acquisition of rotation rate, acceleration, and tilt data for heavy-duty, off-highway, or other specialized vehicles. The sensors are available from SE Spezial-Electronic. The vehicle network protocol is SAE J1939. The reference sensor unit Tars-IMU operates either with a 5 VDC or 9 to [...]
IoT Development With ESP32 - Build Exciting And Powerful IoT Projects
The ESP32 is a series of low-cost, low-power System-on-Chip (SoC) microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series uses a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management modules. Other components include around 48 I/O pins (variable) [...]
ARM Cortex Automotive-Grade SoC (System on Chip) With Two CAN Bus Interfaces Supports Linux And Android BSP
Advantech announced the release of its ROM-5620 Smarc 2.1 module, its first Arm Cortex A35 based on the NXP i.MX8X application processor. The product is especially applicable for automation equipment and HMI (human-machine interface) devices.The product adopts an automotive-grade SoC (System on Chip) and associated industrial-grade components that provide an operating temperature range from -40 °C [...]
Classical CAN, CAN FD To Ethernet Gateway And Bridge For IoT Connectivity
HMS Networks has extended the functionality of its Ixxat CAN@net NT and CANbridge NT series. Users can now add event-controlled network actions and bi-directional MQTT-messaging to cloud applications.Both product families enable CAN-based networking on-site and remotely. The CANbridge NT allows the coupling of up to four Classical CAN and CAN FD networks using filter and translation rules. Network [...]
Network Gateway For Automotive Ethernet, Classical CAN, And CAN FD
Vector Informatik released its VN5620 network gateway for Automotive Ethernet and Classical CAN, as well as CAN FD networks. The two CAN FD interfaces utilize the TJA1057 transceivers from NXP.The device is suitable for data analysis, simulation, and testing tasks. The data monitoring per Ethernet warrants a transparent connection between two nodes with a precise timestamp. [...]
Embedded Development Kit With CAN FD, LIN BUS, Bluetooth Connectivity For Gateway Design
NXP has released its KW38 micro-controller, which provides all components for automotive gateway designs. The wireless MCUs integrate the long-range capability with Bluetooth low energy (BLE) version 5.0 and generic FSK radio. Delivering a -105-dBm sensitivity with LE-coded 125 kbit/s data rate provides reliable connections in harsh environments and at extended distances. The data stream buffer [...]
Data Acquisition from HD Vehicles Using The SAE J1939 CAN Bus
Modern vehicles are equipped with electronic control units (ECUs) to control various subsystems such as the engine, brakes, steering, air conditioning, and infotainment. These ECUs (Electronic Control Units) are networked to share information, and output directly measured and calculated data. The SAE J1939 in-vehicle network is a data goldmine for enhanced maintenance, measuring vehicle performance and its [...]
