Suspension stabilizing system and vehicle

The invention discloses a suspension stabilizing system and a vehicle, the suspension stabilizing system comprises a stabilizing rod and a rigidity adjusting device connected to the stabilizing rod, and the rigidity adjusting device comprises two groups of pull rod mechanisms which are correspondingly connected to the two ends of the stabilizing rod respectively and are electrically adjustable in length; the rigidity adjusting device further comprises a control module used for controlling the two pull rod mechanisms to conduct length adjustment, and the control module sends instructions to the pull rod mechanisms at the two ends according to the real-time working condition of vehicle running and correspondingly controls the pull rod mechanisms at the two ends to stretch and retract. The anti-roll rigidity of the stabilizer bar to the vehicle body is changed through extension and contraction of the pull rod mechanism; the length of the stabilizing pull rod is adjusted through electric control, so that the tors
