Title: Drive force distribution control device
Inventor: WATABE YOSHITOMO
IPC: B60T8/1755
Filed: 2007-02-05
Abstract: <P>PROBLEM TO BE SOLVED: To provide a drive force distribution control device capable of safely executing small round control.  <P>SOLUTION: The drive force distribution control device is provided with an air pressure information obtaining means 41-44 for obtaining information regarding an air pressure of respective wheels 21-24 of a vehicle 1. When the small round control that the drive force of an inner wheel is reduced and a rotation radius is further reduced than the minimum rotation radius determined by mechanical characteristic of the vehicle 1 is performed at turning of the vehicle 1, distribution of the drive force relative to the front and rear inner wheels of the vehicle 1 is changed by a drive force changing means 55 based on the air pressure information of the turned inner wheel. Thereby, it is avoided that the inner wheel with the reduced air pressure is turned by the small drive force, thereby, removal of a rim is avoided.  <P>COPYRIGHT: (C)2008,JPO&INPIT
