A vehicle drive control system including a motor brake control device. The motor brake control device causes an AC motor to generate a braking force, and selectively executes a first three-phase (3-phase) short-circuiting mode for simultaneously turning on switching elements of an upper arm of an inverter and a second 3-phase short-circuiting mode for simultaneously turning on switching elements of a lower arm of the inverter. The first 3-phase short-circuiting mode and the second 3-phase short-circuiting mode are selectively executed. |
