| Summary: | The article analyzes the influence of modern-day vehicle suspension characteristics on the passenger's comfort sensation. Cars with air suspension were selected for experiments and the suspension was equipped with mode selection options – „Comfort“ and „Sport“. With a steering wheel rotation robot, a sinusoidal manoeuvre is ensured. The experimental tests have been carried out by changing car suspension modes and wheel sizes. Experiments and data processing were carried out in accordance with provisions of the international standard ISO 2631-1. In the experimental test, the longitudinal and lateral acceleration projections captured by the sensor and roll rate of the vehicle have been set to provide the most comfortable adjustment of the car suspension mode. After filtering the measured vertical acceleration values, the comfort sensation is expressed as the root mean square (RMS) of vibration acceleration value. After evaluating the passenger's sense of comfort, a summary of the effect of the car suspension-driving mode is provided. |
