Vehicle Ergonomics and Efforts
Ergonomics and efforts play a vital role in the consumer decision making journey. Advanced structures provides an extensive range of solutions for evaluating the comfort levels in different usages and the effort required for steering, pedals etc.
Vehicle Ergonomics, Dimensions & Efforts
The tests included here cover all aspects of vehicle architecture , ergonomics and efforts related to customer touch points. Our expert engineers are equipped with all types of effort sensors , Seat pressure sensors , H-Point Measuring Machines , 3D Scanning tools and Standard processes. We have developed and refined these process over time while benchmarking numerous vehicles.Our reporting doesn't stop at giving list of dimensions or data in Excel files, rather detailed scanned 3D Data with dimensions, where the users can measure dimensions themselves if required.
Effort test measures the effort required to turn the steering from lock to lock – when the car is stationary and also when the car is in motion. It lets you know just how much effort it would be to park a car. It also measures how many turns it takes to turn from full left to full right (lock-to-lock).
The test also measures how much effort it takes to press the clutch. This is an important factor given the bumper-to-bumper traffic conditions you face in many cities. Some cars really have hard clutches, which could lead to leg pain and fatigue in city driving conditions.
The testing equipment: Here’s what the set up consists of:
Torque Steer and angle sensor: The second steering that is fitted on top of the car’s original steering is actually a torque steer and angle sensor. It measures the effort (or torque) required to turn the steering wheel.
Pedal force sensor: The second piece of equipment used is a pedal force pressure sensor. It measures the effort it takes to press the clutch.
Gear lever force sensor: This is a sensor that sits parallel to the gear knob and senses the effort (in KgF) that the driver has to use to change the gear.
What affects this test:
The steering effort and clutch effort tests are greatly affected by the condition of the vehicle. Which is why, for our tests, all the vehicles tested have below 15,000 km on the odometer – so that normal wear and tear is not a significant factor affecting the test. Also the kind of steering – whether it is electronic power steering or a hydraulic power steering – also matters. Electronic power steering units take far less effort to turn compared to hydraulic power steering equipped cars.Similarly, for clutch effort – cars with a hydraulic clutch usually feel slightly heavier compared to smaller cars with cable operated clutches. But here too, the design of the clutch is important.
The tabulation of results:
Steering effort at parking speeds and in slow-speed city traffic is noted as mentioned in Newton Metres. The average of five readings is taken as the final reading – and this is compared with other cars in its segment. If the reading falls above the segment average, the car has a “heavy” steering and if it falls at or below the segment average, the car has a “light steering”.
The same measurement is done for clutch pedal effort as well. The average of the segment is taken and a car’s clutch can then by scientifically proven to have a “heavy” clutch or “light” clutch. The effort to shift gears is also measured in KgF.
In the CAR Y for instance, the lock-to-lock turns took a 450 degree angle with an approximately 6 Nm amount of torque needed. The spikes in torque are when it hits the bump stops. In relative score, the Car Y scored 30 while the Car Z scored 33 – both with relatively well-weighted power steering systems, with the Car Y requiring marginally less effort.
