電動車両の制御装置
Document Type and Number:
Japanese Patent JP7115647
Kind Code:
B2
Abstract:
Provided is an electric vehicle control device that, for an electric vehicle, enables both suppression of fuel economy deterioration and improvement of acceleration performance. A control device (20) is for an electric vehicle (1) that includes an internal combustion engine (2), a generator (4), a front motor (6) and a rear motor (8), and a drive battery (10). The generator (4) is driven by the internal combustion engine (2). The motors drive a drive shaft of the electric vehicle (1). The drive battery (10) supplies electric power to the motors. The control device (20) for the electric vehicle (1) is provided with: a travel mode control unit (30); a battery output deficiency determination unit (32); and a power generation control unit (34). The power generation control unit (34) controls the internal combustion engine (2) and the generator (4) on the basis of a first electric power. The power generation control unit (34) has a first control mode and a second control mode. The first control mode involves controlling the internal combustion engine (2) to change the rotation speed of the internal combustion engine (2). The second control mode involves controlling the generator (4) to change the rotation speed of the internal combustion engine (2). If the travel mode control unit (30) has switched to a series mode and the battery output deficiency determination unit (32) has determined that a second electric power is deficient, then the power generation control unit (34) switches from the second control mode to the first control mode.
