Abstract: A vehicle includes a system for controller the vehicle. The vehicle includes a motor. The system includes an inverter, and a gate controller. The inverter has a switch for controlling current to the motor. The gate controller is configured to apply a gate current to the switch at a first on-current control level during a first switch-on stage of a turn-on operation of the switch, lower the gate current to a second on-current control level less than the first on-current control level during a second switch-on stage of the turn-on operation, and raise the gate current to a third on-current control level during a third switch-on stage of the turn-on operation, wherein the third on-current control level is greater than the second on-current control level.
