Arkadaslar statik surtunme katsayisi kinetikten yuksektir, bu genel birsey, yuvarlanma direnci ile alakasi yok. Genel bir varsayim.
Simdi makalelere baktim, genelde kuru zeminde dusuk hizlarda abs siz arac daha kisa mesafede duruyor. Surat arttikca abs one geciyor ve yuksek suratlerde acik farkla daha kisa mesafede duruyor. İslak zeminlerde abs hep daha kisa mesafede duruyor.
Forkenbrock et al. (1998, 1999) performed a test track evaluation in an attempt to identify areas where ABS-fitted vehicles did not perform as well as their non-ABS-fitted counterparts. They evaluated the performance of nine production vehicles in seventeen stopping scenarios. Some of the scenarios included a straight-line stop, a straight-line stop with transition to different surface friction, a curve stop and a J-turn stop. Two different pedal applications were used and vehicles were tested in both lightly and heavily laden conditions. In most scenarios, ABS stopping distances were shorter than with the ABS disabled, the exception being gravel where stopping distances increased by an average of 27%. In almost all manoeuvres vehicle stability was superior when ABS was operational.
Marshek et al. (2002a, 2002b) used an ABS index of performance (ABSIP), i.e. the ratio of average ABS braking deceleration to locked wheel deceleration, to evaluate braking performance and characteristics. They conducted track tests on bitumen using six vehicles and found that deceleration in ABS-fitted vehicles was a significant function of vehicle speed. The results showed that both ABS and locked wheel braking varied significantly between vehicles. In general, ABSIP was greater than 1 at higher speeds (>35km/h) and less than 1 at lower speeds (<35km/h), indicating that ABS degrades braking performance at lower speeds and improves braking performance at higher speeds.
