Abstract:
A potential collision is predicted by comparing estimates of the time-to-brake (TTB) and the time-to-turn (TTT) of a host vehicle (10) with a computed time-to-collision (TTC) (24; 64, 66, 76). The collision is deemed to be unavoidable when the smaller of TTB and TTT is greater than TTC. The TTT estimate is based in part on the lateral acceleration capability of the vehicle (10), and the lateral acceleration is initialized to a low value corresponding to its instantaneous capability (52), and is set incrementally higher than the actual lateral acceleration when the driver initiates evasive turning (54). The TTT and TTB estimates are increased by the time required to pre-charge the vehicle brakes (70, 80) so that brake pre-charging can be automatically initiated (74, 84) when required to optimize collision mitigation due to braking.
Abstract:
A compressed data table is formed from an uncompressed data table by defining a code description bit structure having a code type and a run length of data items. The code type may be configured to identify byte-length data items, word-length data items and/or one or more user-specified data items. Each run of one or more byte-length, word-length or user-specified data items in the uncompressed data table is represented in the compressed data table with a code description bit structure having an appropriately configured code type and having its run length equal to the number of byte-length, word-length or user-specified data items in the run of one or more byte-length or word-length data items, and in the case of byte-length and word-length data items each code description bit structure is followed in the compressed data table by the one or more byte-length or word-length data items.
