Abstract

The invention provides a vehicle controller and a control method thereof; the vehicle controller control method comprises the following steps: a power supply control unit sends a first control order to an or gate circuit, the or gate circuit forms a power supply control signal according to the first control order; the or gate circuit sends the power supply control signal to a driving circuit, andthe driving circuit forms a power supply power signal according to the power supply control signal; the driving circuit sends the power supply power signal to a feedback circuit; the power supply control unit also sends self state information to a central processor, and the central processor controls the feedback circuit to connect / disconnect according to the state information; the feedback circuit forms a second control order according to the power supply power signal when the feedback circuit is conducted; the feedback circuit sends the second control order to the or gate circuit, and the orgate circuit continuously outputs the power supply control signal according to the second control order.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a vehicle controller and a control method thereof. Background technique [0002] At present, on the vehicle controller products, the power control function is realized by adding a power control chip, which cannot meet the functional safety design. When the power control chip fails, the power supply of the vehicle is suddenly interrupted. If the vehicle is driving at high speed, A power outage can lead to serious traffic accidents and consequences. Therefore, if you want to realize redundant control of the vehicle power supply, you need to achieve the output of dual power supply control signals, which often requires the use of dual power supply control chips, that is, two power supply control chips are used on the product to output a power supply control signal respectively. Realize the power control function. If one of the two chips fails and cannot output its own...
