Title: Car body speed computation device
Inventor: TSURUHARA RYUZO
IPC: B60T8/66
Filed: 2005-07-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a car body speed computation device, capable of correctly carrying out car body speed computation.  <P>SOLUTION: Car body speed VSO is computed based on wheel speed of wheels that are not being braked in a case where either of front wheels FW and rear wheels RS are being braked. In case where either of the front wheels FW and the rear wheels RW are being braked, the wheels being braked and the wheels not being braked are detected, and the car body speed VSO is determined based on the wheel speed of the wheels not being braked. Even when the wheel speed of the wheels being braked becomes higher than the wheel speed of the wheels not being braked due to road surface states or vehicle states or the like, the car body speed VSO is determined securely based on the wheel speed of the wheels not being braked. Compared to a case where the car body speed VSO determined based on the higher one of wheel speed of the front wheels FW and the rear wheels RW even during braking, the car body speed VSO can be determined more correctly.  <P>COPYRIGHT: (C)2007,JPO&INPIT
