Embodiment Construction

[0047] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0048] figure 1 It is a functional block diagram of the control method of the VCU power supply system provided by the embodiment of the present invention, as figure 1 As shown, the steps include:

[0049] Step S101 , detecting multiple types of operation signals of the electric vehicle at least including key signals, charging signals, and bus signals.

[0050] Step S102, converting the detected operation signal to obtain a wake-up signal for waking up the power system.

[0051] Step S103, outputting the wake-up signal to the power system, so as to start the power system. That is to say, after the power system is started, the power system supplies power...

Abstract

The invention discloses a method and apparatus for controlling an entire vehicle controller power system of an electric car, and relates to the electric car control field. The method includes detecting the operation signals including key signals, charging signals and bus signals of the electric car, converting the detected operation signals to obtain wake-up signals to wake up the power system, and inputting the wake-up signals to the power system to start the power system. Power on / off of an entire vehicle controller is realized through inputting various types of operation signals.

Description

technical field [0001] The present invention relates to the control field of electric vehicles, in particular to a control method for a power supply system of a vehicle control unit (Vehicle Control Unit, VCU) of an electric vehicle and a related control device. Background technique [0002] VCU is the core component of the electric vehicle control system. Specifically, when the electric vehicle is started by the key, the internal power chip of the VCU receives the enable signal, the power chip starts to work, and outputs a power supply voltage that meets the requirements of the functional chip, the VCU is awakened, and the electric vehicle starts normally. When the electric vehicle has no control requirements, such as in the parking state, the VCU executes the power-off action. Specifically, the VCU receives the power-off command signal, such as the key power-off signal. The set control logic performs cut-off and enable signal processing on the power chip inside the VCU, t...
