Abstract: 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.

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. Preferably, the first memory is a volatile memory and the second memory is a non-volatile memory.

Abstract: System and method for optimizing the efficiency of base-to-vehicle communication. The method includes beginning a call initiation step for establishing a wireless communication between a base station and a remotely located vehicle. Conditions are sensed at which a prospective wireless communication would be conducted. The sensed conditions are analyzed to determine whether predetermined criteria are met for initiation of the prospective wireless communication. It is then chosen to initiate a wireless communication when the predetermined criteria for initiation of the prospective wireless communication is satisfied based on the analysis of sensed conditions. It may be required that from the sensed conditions it be determined that the remotely located vehicle is traveling below a predetermined threshold speed. Alternatively, the determining condition may be transmission quality for the prospective wireless communication.
