The utility model provides an all-in-one controller for a new energy commercial vehicle. The all-in-one controller is characterized in that a main drive module, a power-assisted steering controller, an air compressor controller, a high-voltage power distribution module, a DCDC module and an insulation monitoring module are integrated in a box body; the main driving module is composed of a control board and a driving board and is of an up-down laminated structure, and driving devices in the driving board are connected in parallel through IGBTs. The power-assisted steering controller and the air compressor controller share the MCU circuit and the power supply circuit; the DCDC module is an independent module; the high-voltage power distribution module is composed of contactors and a high-voltage plate and comprises a main drive contactor, an auxiliary drive contactor, a pre-charging contactor, a pre-charging resistor, an electric air conditioner contactor, a pre-charging contactor, a pre-charging resistor, an e
