Embodiment 1

[0056] Such as figure 1 As shown, in a first aspect of the present invention, there is provided an isolation component, comprising:

[0057] Processor, transceiver, switch module, switch driver module and power management module;

[0058] The output terminal of the processor is connected to the input terminal of the switch driving module, the output terminal of the switch driving module is connected to the input terminal of the switch module, and the input terminal of at least one power monitoring module is connected to the first terminal or the second terminal of the switch module , the output terminal of at least one power monitoring module is connected to the input terminal of the processor, and the transceiver is connected to the processor;

[0059] The switch module is used to be connected in series in the power supply circuit through the first terminal and the second terminal of the switch module, the processor is used to send control instructions to the switch drive mo...

Embodiment 2

[0064] On the basis of Embodiment 1, the present invention also provides a redundant architecture for autonomous driving vehicles, including a first isolation component and a second isolation component, the first isolation component and the second isolation component are the isolation components described in Embodiment 1 , the redundant architecture of the self-driving vehicle also includes: a power generation device, a main battery, a secondary battery, a first driving system and a second driving system; Between the first isolation part, the power generation device, the second isolation part and the auxiliary battery are connected in series in sequence, and the second driving system is connected between the auxiliary battery and the second isolation part; the power generation device is used for the main battery and the auxiliary battery after the vehicle is started. Battery charging, and power supply for the first driving system and the second driving system; the first isolati...

Embodiment 3

[0080] Such as Figure 7 ~ Figure 8 As shown, this embodiment provides a method for controlling an isolation component, which is applied to the isolation component described in Embodiment 1, including:

[0081]A1. After the processor is woken up, the control switch module is turned on to turn on the current power supply circuit. Among them, the wake-up process of the processor is: the driver starts the vehicle, the power management chip of the isolation component is connected to the IG line of the vehicle (KL15 is powered on), the power management chip is powered on and wakes up and supplies power to the processor to wake up and activate the processor. Because the switch module is a normally open switch module, when the processor sleeps, the MOSFET module of the switch module is disconnected, the first terminal and the second terminal of the isolation part are disconnected, the current power supply circuit is disconnected, and after the processor is activated, the switch The ...

Abstract

The embodiment of the invention provides an isolation component, a redundant architecture of an automatic driving vehicle and a control method of an isolation component, and belongs to the technical field of automatic driving vehicles. The isolation part comprises a processor, a transceiver, a switch module, a switch driving module, a switch state monitoring module and at least one power supply monitoring module; the switch driving module and the switch state monitoring module are connected with the processor and the switch module, the power supply monitoring module is connected with the switch module and the processor, and the transceiver is connected with the processor. The first wiring end and the second wiring end of the switch module are connected in series in the power supply loop, and the switch driving module controls the first wiring end and the second wiring end of the switch module to be connected / disconnected according to a control instruction sent by the processor. The main power supply loop is diagnosed through the isolation part, when the main power supply loop breaks down, the fault loop can be rapidly cut off, the situation that a vehicle is out of control due to power failure is effectively avoided, and the safety of drivers and passengers is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automatic driving vehicles, in particular to an isolation component, a redundant architecture of an automatic driving vehicle and a control method for the isolation component. Background technique [0002] Self-driving vehicles are designed to liberate the driver's hands and eyes, improve driving comfort and safety, and remind the driver to take over the vehicle in time when the system fails. At present, the 12V low-voltage power grid is the basic power supply guarantee for the functional components of the vehicle. However, when the low-voltage power grid system fails, such as short circuit or open circuit, the vehicle's autonomous driving control components cannot work normally, and there is a risk of loss of control, which will endanger the driver. Personal safety. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide an isolation component, a redund...
