Vehicle Performance
The overall performance of a vehicle plays a decisive role in comfort, safety, and marketability. Factors such as noise and vibration behaviour, thermal stability, braking performance, driving dynamics, interior quality, and chassis all interact. With increasing electrification and rising expectations for comfort and efficiency, realistic validation is becoming ever more important.
By testing vehicle systems in both lab and real-world conditions, we deliver a complete picture of performance. With KJ Tech’s support, you can be confident in the safety, reliability, and everyday usability of your technology.
Noise, vibration, and harshness (NVH) directly affect the driving experience and are key indicators of perceived comfort and quality.
With the introduction of electric and hybrid powertrains, the focus shifts from conventional combustion engine sounds to high-frequency motor and drivetrain noise as well as tyre and wind noise. Detailed measurements and analyses under real-world conditions enable precise evaluation and optimisation of NVH characteristics.
Thermal management is essential to maintaining the performance and longevity of powertrains and batteries. Efficiency and safety depend heavily on stable operating temperatures.
Battery systems, power electronics, and cooling circuits must function reliably even under extreme conditions. Thermodynamic testing demonstrates how efficiently systems operate and whether performance is ensured across all application scenarios.
The braking system is one of the most safety-critical components of any vehicle and must function reliably at all times.
Heavier vehicles, recuperation systems, and rising thermal loads bring new demands. KJ Tech tests braking systems in both lab and real-world settings, assessing deceleration, stability, comfort, and integration with electric powertrains, to ensure reliable performance in every driving situation.
Vehicle dynamics describe the interaction of steering, powertrain, chassis, and brakes. They determine safety, stability, and driving comfort.
Different road and environmental conditions demand systems that respond consistently in every situation. Dynamics testing provides insights into vehicle behaviour under critical conditions and supports targeted tuning between comfort and driving enjoyment.
The body and interior represent ergonomics, safety, and comfort. Materials and workmanship must be durable and robust.
Different markets bring varying requirements – from safety standards to comfort expectations. Endurance tests under temperature influences, UV exposure, or intensive use demonstrate whether materials and systems meet the demands for quality and longevity.
The chassis forms the foundation of stability, safety, and driving comfort. New vehicle architectures increase the demands on reliability and balance.
Electric vehicles, with their higher weight and altered load distribution, require precise tuning. Chassis testing on proving grounds and in real-world operation provides valuable insights into suspension, damping, and axle design – enabling targeted optimisation for comfort and performance.
