Reduction of data width in transmitted multi-bit data words in an automotive system is accomplished by truncating the data at its least significant bits and accumulating the truncated bits until, over successive truncated digital words, the sum of the accumulated bits exceeds a threshold equal to the least significant bit of the truncated word. At this time, the truncated word is incremented by one least significant bit and the accumulated value of truncated bits is decremented by an equal amount. In this way, the error does not accumulate in applications which integrate the resulting truncated words.

Apparatus and method for data width reduction in automotive systems

A rollover detection system or apparatus,deployed on a vehicle,. Apparatus,includes a controller,having a memory unit,and operating under stored program control. Controller,is electrically, physically, and communicatively coupled to sensors,, and to vehicle occupant safety devices or assemblies,by use of a communications bus or path,. Controller,receives signals generated by sensors,, processes and utilizes the received signals to determine when a vehicle rollover situation is imminent or relatively certain to occur, and selectively activates safety devices,, if such a determination is made.

Method and apparatus for detecting a vehicle rollover

A system and method for controlling deployment of an inflatable passenger restraint utilize distance-based thresholds to improve deployment time in high-speed crash events and to improve event discrimination for side impacts. The invention uses an acceleration signal to calculate distance and to calculate average acceleration using three buffers holding differing numbers of samples. The three average accelerations are used to determine the length of the acceleration curves above and below the zero axis which is defined as positive and negative jerk. Average acceleration and jerk are compared to the distance-based thresholds to determine whether or not to deploy the inflatable restraint.

System and method for the detection and discrimination of vehicle crash

A single chip sensor processor includes an integrated analog to digital converter (A/D) and digital filter. Analog acceleration signals from a sensor is converted and digitally filtered on-chip in parallel with other processor software executions to effectively increases the bandwidth of the system. The results of the sensor processor calculations may be communicated to a remote microcontroller for deploying a vehicle air bag.
