Passenger mass determining method for use during crash fall of vehicle, involves determining belt force acting on passenger by belt force sensor, where value for passenger mass is derived from division of belt force by sum of accelerations

摘要

The method involves determining vehicle acceleration by using an ESP (RTM: electronic stability control system) sensor (2). The acceleration of a belt strap (16) securing a passenger (102) is determined by a belt rolling angle sensor (3). The belt force, which acts on the passenger is determined by a belt force sensor (4), where a value for the passenger mass is derived from the division of the belt force by the sum of the vehicle acceleration and the belt strap acceleration. Independent claims are also included for the following: (1) a system for determination of the passenger mass of a passenger secured by the safety belt in a vehicle (2) an adaptive seat belt system for a vehicle (3) a computer program with program code units for determining a passenger mass of a passenger secured by a safety belt system (4) a computer program product with program code units for determining a passenger mass of a passenger secured by a safety belt system.
