Metod och anordning för utvärdering av förlopp där en säkerhetsanordning i ett fordon ej har utlösts

摘要

Method and arrangement for subsequent analysis of processes in a motor vehicle where a safety device in the vehicle has not triggered and includes a control device for the safety device and a sensor for detection of processes which can result in that the safety device is triggered if a first parameter exceeds an upper limit. A first memory is included in which parameters regarding the operation of the vehicle are stored when the first parameter exceeds a lower limit, and a second memory to which the parameters are transmitted if the safety device is triggered. The device includes means for transmitting the parameters from the first memory to the second memory if the first parameter exceeds the lower limit during a certain time period and the amount of data in the first memory exceeds a predetermined limit.
