Abstract

A motor control system includes a drive motor and a deck motor that are connected to a battery, an ECU, and a key switch. The key switch acquires that an operation unit has been turned on, and transmits a restart permission signal to the ECU. When SOC of the battery reaches or falls below a first threshold set in advance, the ECU performs a step of disabling all the motors, and when the restart permission signal is received, the ECU performs a step of executing a decelerated travelling mode where the disabled state of the drive motor is released and an allowed speed of the drive motor is reduced.
