Control device of hybrid vehicle

Abstract

It is provided a control device of a hybrid vehicle including a plurality of drive power sources for running including an electric motor driven by electric energy of an electric storage device, the hybrid vehicle configured to perform motor running or assist running using the electric motor for running, the control device being configured to divide a running road acquired from map data into a plurality of sections and stores a change amount of a charged capacity of the electric storage device for each of the divided sections, to acquire all possibly-traveled running routes within a predetermined distance from a current position of the vehicle based on the map data, to calculate a variation characteristic of the charged capacity in correlation with a distance from the current position for each of the running routes based on the change amount of the charged capacity, if it is determined from the variation characteristic of the charged capacity that the possibly-traveled running routes include at least one running route in which electric energy can be recovered to the extent exceeding a predetermined charged capacity upper limit value for permitting charging of the electric storage device, permission being given for the motor running or the assist running using a consumable amount of the electric energy based on electric energy exceeding the predetermined charged capacity upper limit value on the condition that the charged capacity does not fall below a predetermined charged capacity lower limit value for permitting discharging of the electric storage device in all the possibly-traveled running routes even when the electric energy exceeding the predetermined charged capacity upper limit value is consumed before recovery.
