Abstract

The invention provides a vehicle control unit wake-up circuit, a signal processing module and a new energy automobile, the vehicle control unit wake-up circuit comprises a vehicle control unit, the vehicle control unit comprises a first port, at least two wake-up power supplies, and each wake-up power supply is connected with the first port through a diode; and the battery management system comprises at least two second ports, and each second port is connected with one wake-up power supply. According to the scheme, the circuit of the whole vehicle controller circuit board can be simplified, and hard wires used by the whole vehicle main wire harness are reduced.

Description

technical field [0001] The invention belongs to the technical field of circuit design, and particularly relates to a wake-up circuit of a vehicle controller, a signal processing module and a new energy vehicle. Background technique [0002] As people pay more and more attention to the environment, electric vehicle technology becomes more and more mature, making electric vehicles more and more accepted and used by people. In electric vehicles, the vehicle controller, as the brain in the electronic control system, participates in and formulates the functions and strategies of most electronic control systems, and is further used to monitor the running status of other related components in the electronic control system. [0003] As a controller, the vehicle controller, like most controllers, has two states of sleep and wake-up, but the vehicle controller must be in the wake-up state before it can work. During the mode switching process from sleep to wake-up , a valid wake-up si...
