Low-power-consumption whole vehicle controller integrated with gateway function

Abstract

The invention discloses a low-power-consumption whole vehicle controller integrated with a gateway function. The low-power-consumption whole vehicle controller comprises a main control unit, a gatewaycommunication processing unit, an advanced power management unit, an input signal processing unit, an output processing unit, a system storage unit and a breakdown processing unit. A power supply unit supplies electricity to a storage battery, electricity is supplied to a system and a circuit on the periphery of the system by outputting stable voltage through the power supply unit, and normal working of the system is ensured. The main control unit is in data connection with the input signal processing unit, the output processing unit, the storage unit, a breakdown diagnosis unit and the gateway communication unit through a high-speed SPI communication interface, an AD port and a CAN interface, and network information interconnection of a whole vehicle CAN bus is achieved. The low-power-consumption whole vehicle controller can be applied to the situation that a main control unit with pure electric and hybrid vehicle models serving as wholes vehicles coordinates all sub-controllers to work, the new energy whole vehicle controller function is achieved functionally, the gateway function is also achieved, the number of vehicle body electronic controllers is reduced, and the vehicle body space is effectively utilized.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vehicle controller of a new energy electric vehicle, and more specifically to a low-power vehicle controller with an integrated gateway function. technical background [0002] Under the background that low-carbon economy has become the theme of domestic development, nearly a hundred auto companies at home and abroad have entered the field of electric vehicle research and development.
