Abstract

The invention relates to an automotive intelligent fuse box comprising a micro-control unit configured to manage circuit operation, and an intelligent high-side switch configured to drive an electric appliance; the automotive intelligent fuse box is characterized in that the micro-control unit makes a protection judgment on the circuit by comparing a current signal, fed back by an intelligent high-side switch, of an electric appliance with a threshold overcurrent.

Description

Technical field [0001] The present invention relates to an inventory of automotive power control technology, and in particular, there is a vehicle fuse box having driven and protective effects. Background technique [0002] In today's car market, the electrical load on the car is a fuse box to be responsible for power distribution and protection in the vehicle. Two types of fuses and relays are mainly mounted inside the fuse box, which are functioning in circuit protection and electrical drive. When the current is abnormal due to short circuit and overload, the fuse box will be fuse after the current increases, and the temperature has increased after a period of time, thereby achieving the purpose of protecting the components in the automotive circuit. In order to facilitate centrally managed and replacing fused fuses, several fuse boxes are typically configured: for example, the front cabin in the engine compartment is responsible for the electrical appliance outside the vehicle...
