IPC: B60L50/16
Filed: 2002-11-12
Abstract: <P>PROBLEM TO BE SOLVED: To attain a high brake performance by setting an appropriate distribution ratio of regenerative braking force between first and second motor generators connected, respectively, with the front and rear wheels of a hybrid vehicle.  <P>SOLUTION: A hybrid vehicle V is driven or subjected to regenerative braking by connecting an engine E with front wheels Wf through a first motor generator MG1 and a transmission T, connecting a second motor generator MG2 with rear wheels Wr, and connecting the first and second motor generators MG1 and MG2 with a battery B. During regenerative braking of the hybrid vehicle V, distribution ratio of regenerative braking force between the first and second motor generators MG1 and MG2 is controlled to become an ideal distribution ratio depending on the longitudinal acceleration XG (deceleration) of the vehicle V.
