Failsafe Emergency Brake System

Failsafe Emergency Brake System

Safety-related test drives where no driver is allowed to sit in the vehicle are constantly increasing. During the test one must ensure that even if any failures of test components occurs the vehicle can safely and quickly be transfered to a standstill. For such purposes VEHICO offers a failsafe emergency brake system, which steps the brake pedal triggered via radio link from outside the vehicle.

The VEHICO Emergency Brake System offers the following features
• fail-safe operation of the brake pedal
The emergency brake system enables a fail-safe operation of the vehicle brake pedal. By its own energy storage it is independent from the vehicle power system and even if the vehicle power fails the system brings the vehicle safely to a halt.

• manual trigger with defined pedal force
With the help of a hand switch a passenger can trigger at any time a manual brake actuation. The adjustable braking force even enables application of panic braking tests or emergency brake maneuvers.

• braking by driver still possible
The driver seat remains free even with installed emergency brake system. Therefore the test car can be driven normally, for example for transfer purposes. The manual control of the brake pedal is still possible.

• auto diagnosis
The system has extensive auto diagnostic algorithms and is monitoring itself during the entire test period. If an irregular situation is determined, this is immediately reported and a security maneuver is initiated.

• stand-alone system
For security reasons the system was designed that it can be operated independently from other systems installed in the test vehicle. It is a perfect addition for vehicles with installed driving robots or proprietary driving dynamic controls in order to guarantee the safety of the entire system during autonomous vehicle testing.
