From Sensor Signals to Machine Decisions

Mobile towing and recovery equipment operates in conditions that challenge even well-designed machine systems: uneven ground, variable boom positions, changing loads, hydraulic shock, and temperature extremes. For OEMs, the engineering objective is not simply to add sensors. It is to integrate reliable machine feedback into a control architecture that can interpret operating conditions, support the operator, and apply appropriate control responses.

GS Global Resources works with OEMs to develop integrated hydraulic, electronic, mechanical, and software solutions for complex mobile equipment. In large and intricate machines like the towing example, that systems-level expertise can bring together angle, position, pressure, and temperature feedback, gathered from industry leading sensors like Parker Hannifin’s Universal Tilt Sensor (UTS), to create a more complete view of a machine state—supporting setup, lifting operations, stability awareness, and durable field performance.

What is mobile equipment sensor integration? Mobile equipment sensor integration is the process of connecting machine feedback—such as orientation, position, hydraulic condition, and temperature data—to electronic controls, operator interfaces, and electrohydraulic functions. For OEMs, it helps create a more informed, responsive, and adaptable machine-control platform.

The OEM Challenge: Turning Sensor Inputs into Machine Intelligence

A tow truck’s boom, outriggers, hydraulic functions, and chassis must work together during recovery and lifting operations. Individual sensors can measure a specific condition, but the real value comes from how those signals are evaluated by the controller and communicated through the operator interface.

The sensors provide real-time feedback from the machine and the controller then interprets that information against configured operating logic. Finally, the operator display presents useful status information, and the electrohydraulic control system can guide, limit, slow, or stop selected functions when conditions require it.

This approach creates a scalable foundation for machine functions that are difficult to achieve through isolated components or manual processes alone.

A Distributed Sensor Architecture

GS Global Resources utilizes sensor feedback in a variety of machine applications, but let’s specifically look at towing applications. By integrating sensor feedback from multiple areas of the machine, we can give operators a complete view of the machine status. Each signal contributes a different part of the overall operating picture.

Integrated feedback area	What it supports
Machine orientation and position	Operator awareness of truck and boom configuration during setup and operation
Support and hydraulic feedback	Confirmation of machine support conditions and hydraulic-system status
Stability-related inputs	Control strategies designed to help manage changing operating conditions
Thermal monitoring	Temperature-aware operation and opportunities for future control enhancements

The combination of these inputs allows the control system to understand more than one isolated condition. It can interpret how the chassis, outriggers, boom, hydraulic system, and operating environment relate to one another at a given point in the machine cycle.

Using Feedback for Protective Control Logic

Sensor integration becomes especially valuable when the machine needs to respond to changing conditions during operation.

For example, inclination feedback can be used by control logic to monitor for a worsening tip condition as a load is lifted. The sensor provides the measurement; the control system determines the appropriate response based on the OEM’s programmed logic and operating requirements.

It’s an important distinction to make: good quality sensors are important, but a sensor alone does not make a machine safer or smarter. The benefits come from the integration of:

• High quality sensing technology.
• Accurate signal processing.
• Well-defined control logic.
• Clear operator feedback.
• Electrohydraulic command of the affected machine functions.

Engineering for Demanding Hydraulic Environments

A productive sensor architecture must also survive the physical realities of the hydraulic system it monitors. In the tow-truck application, boom-cylinder pressure transducers were subjected to harsh hydraulic shock loads that could damage the machine’s sensors. GS Global Resources was able to incorporate a damping feature, reducing the damaging effects of pressure spikes before they reach the sensing element.

For OEMs, this is a practical example of application engineering beyond a standard component selection process. Successful sensor integration requires an understanding of the mechanical and hydraulic environment surrounding the device—including pressure transients, shock loading, mounting, duty cycle, operating temperature, and the consequences of component failure.

Building a Platform for Future Functions

An integrated sensing architecture also creates opportunities to add machine capability without redesigning the entire system.

In the initial iteration of a tow-truck application, the system already monitored hydraulic tank temperature. To utilize that information, GS Global Resources utilized the existing temperature feedback as the confirmation signal for a hydraulic warm-up sequence. If oil temperature is below a configured threshold, the system can run the warm-up routine and delay normal operation until the hydraulic fluid reaches an acceptable temperature.

Because the system was already set up to monitor the tank temperature, it was relatively simple to use that information for some other long-term value. Any signal initially used for monitoring can later support additional logic, such as:

• Cold-weather machine warm-up.
• Operator advisories.
• Function enablement conditions.
• Performance optimization.
• Remote diagnostics or connected-machine data strategies.

Sensor Integration for Smarter Mobile Equipment

For tow-truck and other mobile-equipment OEMs, the goal is not to add sensors for their own sake. The goal is to create a control system that understands the machine’s operating condition and uses that information effectively.
