Stability and trajectory controlling system for hybrid vehicle, has electrovalves associated with non-motorized and motorized calipers, where system decreases pressure in motorized calipers by actuating electrovalves and concerned calipers

摘要

The system has on-off type proportional opened isolating electrovalves (6a-6d) associated with non-motorized calipers (7a, 7c) and motorized calipers (7b, 7d), respectively. Hydraulic pumps (9a, 9c) are associated to the non-motorized calipers. The system individually decreases the pressure in the motorized and non-motorized calipers by actuating the electrovalves associated to the calipers that are jointly concerned to the activation of the hydraulic pumps and by electrically actuating the concerned motorized calipers.
