The safety device in order to decrease the mannered null accident damage for

摘要

This invention the operational state data to be acquired by the operational state sensor system (2), retardation of longitudinal direction of the vehicle (|a_x|) And in regard to braking torque request (B) the safety device in order is watched by the operator, to decrease the damage of accident it regards the method for the protective system where the inside of the vehicle which it has (1) operates preventively. Extraordinary braking state (NB) in order to judge, braking request appraisal expedient (3) is used. Retardation of longitudinal direction (|a_x|) Retardation threshold of longitudinal direction (S_LV), the safety device (1) one it is started at least only when it is below.
