METHOD AND DEVICE FOR PROCESS EVALUATION WHERE A SAFETY DEVICE IN A VEHICLE HAS NOT TRIGGERED

摘要

The invention relates to a device for subsequent analysis of processes in a motor vehicle where a safety in the vehicle has not triggered and comprises a control device for said 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. The invention also comprises a first memory in which parameters regarding the operation of the vehicle are stored when said first parameter exceeds a lower limit, and a second memory to which said parameters are transmitted if the safety device is triggered. Furthermore, the device comprises means for transmitting said 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. Preferably, the first memory is a volatile memory and the second memory is a nonvolatile memory.
