Abstract:
A vehicle operational cost display system includes a user interface adapted for entry of cost of fuel for operation of a vehicle; a central processing unit interfacing with the user interface, the central processing unit having a calculator function adapted to calculate total operational cost of the vehicle based on the cost of fuel for operation of the vehicle and distance traveled; and a display interfacing with the central processing unit, the display adapted to display the total operational cost of the vehicle. A vehicle operational cost display method is also disclosed.
Abstract:
A controller and a control strategy minimizes shift shock in a hybrid electric vehicle during a downshift conducted while the vehicle is in a regenerative braking mode by maintaining total powertrain torque at a desired target during the downshift. The controller has three preferable modes including modulating just engine torque, modulating just electric motor torque or simultaneously modulating both motor and engine torque.
