Abstract (en)

[origin: CA2653747A1] Disclosed is a method for regulating an active chassis of a tracked vehic le, said chassis comprising at least one wheel unit (105) with two wheels. A ccording to the inventive method, the turning angle of the first wheel unit (105) about a vertical chassis axis relative to a vehicle structure (102) th at is supported on the first wheel unit by means of a first primary spring m echanism (107) is adjusted in a first frequency range with the aid of at lea st one first actuator (109) which acts between the first wheel unit (105) an d the vehicle structure (102), the adjustment being made in accordance with the actual curvature of the track, and/or the turning angle of the first whe el unit (105) about the vertical chassis axis relative to the vehicle struct ure (102) is adjusted in a second frequency range in such a way that transve rsal movements at least of the first wheel unit (105) caused by a track disp lacement or a sinusoidal course are counteracted. In the first frequency ran ge, the turning angle of the first wheel unit (105) is adjusted using a firs t desired value corresponding to a first ideal value multiplied by a first c orrection factor (K1), said first ideal value being selected such that the f irst wheel unit (105) is adjusted at least approximately by the radius of cu rvature if the first desired value matches thefirst ideal value (i.e. K1=1), and/or in the second frequency range, the turning angle of the first wheel unit (105) is adjusted using a second desired value which corresponds to a s econd ideal value multiplied by a predefined second correction factor (K2), said second ideal value being selected such that transversal movements at le ast of the first wheel unit (105) caused by a track displacement or a sinuso idal course are essentially compensated if the second desired value matches the second ideal value (i.e. K2=1).
