Divya,
The fleet and asset management features of OTM are being provided in version 6.0 and subsequent CUs. This functionality will leverage OTM, portions of EBS and Siebel to provide a comprehensive solution.
For the information that has been released, I encourage you to view the following presentation by Jim Mooney.

In addition, there will be a presentation by Oracle (and likely Jim) at the upcoming OTM SIG Users Conference in August -- I definitely encourage you to attend.
