PROBLEM TO BE SOLVED: To provide a hybrid vehicle control device in which a driver can be notified of battery residual lowering more certainly.SOLUTION: A control unit 100 implements an enforced electric power generation mode in which electric power generation by a generator 20 is performed through operating an engine 10 and at least a part of electric power supplied to a running motor 40 is covered by the generated electric power of the generator 20 when a battery residual is less than a first threshold value, and implements an emergency electric power generation mode in which the engine 10 is operated at higher engine speed than that of the enforced electric power generation mode and electric power generation.by the generator 20 is performed when the battery residual is less than a second threshold value which is smaller than the first threshold value. The control unit 100 increases the engine speed by a specified amount so that the higher the vehicle speed becomes, the larger the sound pressure level in a cabin becomes while keeping an engine output constant by making a throttle opening small upon transferring from the enforced electric power generation mode to the emergency electric power generation mode. |
