Embodiment Construction

[0043] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0044] Embodiments of the present invention provide a high-voltage power-off control method, which is applied to a VCU. Such as image 3 As shown, the VCU performs signal interaction with the instrument, vehicle body controller and battery management system BMS through a controller area network (CAN, Controller Area Network), and performs signal interaction with the robbery alarm button through a hard-wired signal.

[0045] Such as figure 1 A...

Abstract

The invention discloses a high-voltage power-down control method, control device, control apparatus and an automobile. The method comprises: monitoring whether the electric vehicle meets the preset conditions under high voltage, The preset conditions include: When the battery management system BMS communicates normally in driving mode, the remaining battery power value cannot meet the driving demand, When the BMS is in the driving mode, the estimated remaining electric quantity value of the power battery cannot meet the driving demand, the electric vehicle collides when in the driving mode, analarm signal is received when in the driving mode, and a high-voltage electric shock risk signal is detected during the charging process of the remote control mode. When it is detected that the electric vehicle currently satisfies at least one of the preset conditions, a high voltage down-state control signal is sent to the BMS. The embodiment of the invention can effectively avoid the overdischarge of the power battery and ensure the safety of the driver and the vehicle.

Description

technical field [0001] The invention relates to the technical field of power-off of an electric vehicle, in particular to a high-voltage power-off control method, a control device, a control device and an automobile. Background technique [0002] Vehicle power-on and power-off control is an important part of pure electric vehicle vehicle control. Different from traditional fuel vehicles, pure electric vehicles have many high-voltage and low-voltage components. For this reason, detailed strategies need to be formulated to ensure that the vehicle is in danger of high voltage. Protect the battery from over-discharge to ensure the safety of the driver and the vehicle. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a high-voltage power-off control method, a control device, a control device and a vehicle, which solve the problem of high-voltage power-off in vehicles. [0004] According to one aspect of the prese...
