The invention discloses an automobile power distribution protection circuit and an automobile power distribution protection method. The automobile power distribution protection circuit comprises electric equipment, a driving chip which is connected with the electric equipment through an automobile wire harness and used for acquiring a first current signal passing through the automobile wire harness, and a control chip which is electrically connected with the driving chip and used for controlling the automobile power distribution protection circuit based on the acquired first current signal sent by the driving chip. The driving chip is used for determining the wire harness temperature of a vehicle wire harness connected with the electric equipment in the automobile power distribution protection circuit and determining a control command for controlling the vehicle wire harness based on the wire harness temperature, and the driving chip is further used for receiving the control command and controlling the vehicle wire harness according to the control command. And under the condition that the control command is determined to disconnect the connection between the vehicle wire harness and the electric equipment, controlling the disconnection between the wire harness and the electric equipment. Therefore, while the power distribution circuit is protected, the wiring harness cost is saved, and the space in a vehicle is saved.
