Abstract
A vehicle control device that includes a search unit that searches, based on geographic information to be supplied from a navigation device, for a deceleration start position before a downhill that is suited to regeneration by a motor; and a charge level control unit that performs, when a vehicle reaches the deceleration start position, deceleration control for reducing a charge level of a battery by reducing a vehicle speed. When the charge level control unit performs the deceleration control, the vehicle speed is reduced by reducing a driving force of the vehicle to a level at which only motor output is used as the driving force.
Claims9
A vehicle control device including
- an engine, and
- a motor that is driven by power supplied from a rechargeable battery, the vehicle control device controlling a vehicle that uses at least one of engine output and motor output as a driving force, the vehicle control device comprising:
- a search unit that searches, based on geographic information to be supplied from a navigation device, for a downhill on which regeneration by the motor can be performed;
- and
- a charge level control unit that performs, at a deceleration start position before the downhill that has been specified, deceleration control for reducing a charge level of the rechargeable battery by reducing a vehicle speed, wherein
- in the deceleration control, the vehicle speed is reduced by reducing the driving force of the vehicle to a level at which only the motor output is used as the driving force.
