MAHA’s MFP 3000 is the first test bench that enables a test drive and the efficiency test for safety and driving assistance systems to be performed on a lift. This makes the inspection workflow more efficient and provides greater safety in road traffic. The test bench will make its world premiere at Automechanika 2014.

Active safety systems and driver assistance systems reduce the risk of an accident and increase road safety. This increased safety is only long-lasting, however, if the systems are inspected a few years down the line to check that everything is still working correctly (in the vehicle review performed by vehicle workshops and the periodic technical inspection carried out by inspection organisations). This is why the new PTI Directive 2014/45/EU prescribes the testing of safety-related vehicle systems across Europe.

Efficiency testing better than electronic diagnosis
Until now, electronic safety systems have been tested on the basis of the error lamp status or by reading the error memory. These test methods only provide limited information on how well the safety systems are actually working. MAHA’s innovative driving test bench MFP 3000, on the other hand, provides a real efficiency test of the safety and assistance systems. With the MFP 3000, the inspector can drive the vehicle as if it were on the road and check that the various systems are working correctly, such as the ABS, the ESP, the electronic differential lock, the ACC and the cornering lamps – all while the vehicle is on the lift.

The MFP 3000 provides time savings for the test drive required for the vehicle inspection, and the vehicle does not need to be moved for the following vehicle review. This protects the environment in areas with high traffic congestion and shortens the inspection procedure.

Vehicle fixed on to wheel-free jack
The MFP 3000 is mounted on a MAHA DUO CM scissor lift. It consists of roller sets that can be placed against the raised vehicle hydraulically, a controller that can be integrated into the lift’s control cabinet and a display unit.

For the test drive, the vehicle is driven on to the lift and lifted by the wheel-free jack until all wheels are raised. This is all that is required to fix the vehicle securely to the lift. You can then press a button to make the hydraulic system place the test rollers against the wheel in a matter of seconds. The test drive can then begin, at speeds of up to 80 km/h. The test process is fully automated. The steering wheel can be turned during the test drive to simulate cornering.

Integrated drive motors
Electric motors are integrated in the MFP 3000’s rollers, in addition to the sensors. They are able to drive the wheels of the test vehicle with speeds of up to 60 km/h. The motors also ensure that the driven and non-driven axles run synchronously. The drive and braking torques acting on the wheels are measured by the control electronics and displayed on a monitor. This allows the inspector to see immediately whether the safety or assistance system is reacting to a particular action as expected.

The MAHA driving test bench MFP 3000 will be launched at Automechanika 2014 in Frankfurt. Industry professionals can see the test system, the only one of its kind in the sector, in action live at the MAHA stand in hall 8.0/A02.
