Don’t you just love the way companies come up with unique names and acronyms almost at random? Such is not completely the case here.
Honeywell unveils what is calling a transportation attitude reference sensor (TARS). Essentially, it is an array of sensors in a single package that enables autonomous vehicle (AV) characteristics and enhances efficiency for heavy-duty, off-highway vehicles. The array can report vehicle angular rate, acceleration, and inclination data for construction equipment, such as excavators, skid steer loaders, and backhoes.
The TARS inertial measurement unit integrates with a vehicle’s electronic control unit to provide actionable information about the movement of the machine. For example, the system can limit wheel slippage incidents by sensing vehicle movement. If it identifies traction loss, the vehicle’s control system could be programmed to automatically reduce power to the wheels to prevent an accident.
Whatever you do, don’t stereotype this device. The sensor can be used in a range of applications, including equipment control, linear position, bucket control, vehicle stability control, and operator-assisted control. Features include the ability to report vehicle angular rate, acceleration and inclination, IP67 and IP69K certification for performance in harsh environments, support for 5V and 9V to 36V vehicle power systems, and an operating temperature of -40°C to 85°C (-40 °F to 185 °F).
