The Pedal Force Event Marker Interface
As soon as any pressure is applied to the brake pedal, the interface outputs a digital signal, which can be used to trigger the start of a test. It works in a similar way to a traditional brake pedal trigger, but also allows for the measurement of pedal force and does not need to be stuck to the pedal. Instead, it can be placed next to the VBOX 4 that it is connected to, or securely inside the VBOX carry case.
This gives you a complete solution which measures the amount of force applied to a brake pedal, as well as pedal application, in accordance with SAE J2909 (Braking) and ECE R13H (Braking Assist Systems) regulations.
The VBOX Pedal Force Event Marker Interface constantly monitors the pedal force sensor voltage and adjusts the trigger threshold. This accounts for any fluctuations in pedal force caused by changes in temperature of the sensor itself, preventing incorrect trigger activation.

What is a Pedal Force Sensor and what does it measure?
A Pedal Force Sensor measures the force applied by the driver on brake, accelerator, or clutch pedals. It provides accurate, real-time data on driver input, which is critical for braking performance, drivability studies, and ADAS validation.
Why is pedal force measurement important in vehicle testing?
Pedal force data helps engineers evaluate driver effort, braking efficiency, system response, and comfort. It is especially important in tests like brake performance (stopping distance), AEB validation, and pedal feel analysis.
Where are Pedal Force Sensors typically used?
Common applications include:
- Brake testing and homologation
- ADAS validation (AEB, ACC disengagement)
- Vehicle dynamics and performance testing
Human factors and ergonomics studies
How is a Pedal Force Sensor installed?
The sensor is usually mounted on or behind the pedal assembly, either as a load cell or via a mechanical fixture. Many systems are designed for quick installation without permanent modification, making them suitable for test vehicles.
Can the Pedal Force Sensor integrate with data acquisition systems?
Yes, it can output data via analog, CAN, or digital interfaces, allowing seamless integration with VBOX data loggers. This ensures synchronized recording of pedal force along with speed, position, and other vehicle parameters.
