Sensors enable autonomous operations for heavy-duty vehicles

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.

“Heavy-duty machinery, such as construction vehicles, require skilled, experienced operators to deftly perform complex tasks. An operator error can impede the project schedule or even put worker safety at risk,” said Graham Robinson, president of Honeywell’s Sensing and Internet of Things business.

Robinson continued: “Our new series of transportation sensors can enable ‘intelligent vehicles’ by allowing for autonomy of certain equipment functions. This minimises the risk of operator errors and enables precise movements in challenging work environments.”

The sensor can be used in a range of applications, including: equipment control, linear position, bucket control, vehicle stability control and operator-assisted control.

The TARS series features:

• The ability to report vehicle angular rate, acceleration and inclination
• IP67 and IP69K certification for performance in harsh, challenging environments
• Support for 5-volt and 9-volt to 36-volt vehicle power systems
• Operating temperature of -40 to 85°C (-40 to 185°F)

Honeywell offers other equipment manufacturers the option of a pre-configured sensor, which provides manufacturers convenient and efficient installation.
