Abstract
A motor driving control device drives each of a first motor and a second motor based on a predetermined condition designation signal, and includes a control unit, a first motor driving unit and a second motor driving unit. The control unit outputs first and second PWM signals to control driving of the first and second motors, respectively. Each of the first and second motor driving units flow a current through the first and second motors based on the first and second PWM signals, respectively. The control unit includes a determination means configured to determine whether the condition designation signal meets a predetermined mode switching condition, and an adjustment means configured to perform overlapping-related adjustment of an on period of the first PWM signal and an on period of the second PWM signal, based on a determination result of the determination means.
