<p><P>PROBLEM TO BE SOLVED: To improve stability of a vehicle by appropriately and accurately controlling driving force in any travel scenes such as start and straight travel not only cornering. <P>SOLUTION: A drive force control device 1 includes a first traction control part 2 estimating friction circle limit of a road surface and operating controlled variable of driving force to be reduced as first controlled variable TTCS1 based on the friction circle limit, and a second traction control part 3 operating controlled variable of driving force to be reduced as second controlled variable TTCS2 based on at least slip ratio of wheels. A controlled variable setting part 4 compares the first controlled variable TTCS1 and the second controlled variable TTCS2 and sets smaller one (one having larger reduction) as controlled variable of the drive force control device 1. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
