Embodiment Construction

[0038] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.

[0039] figure 1 It is a schematic diagram showing the vehicle power supply system.

[0040] Such as figure 1 As shown, multiple ECUs 10 of the vehicle ( figure 1 ECU1, ECU2, and ECU3 are shown in the example, here is just an example, the number of ECUs is not limited) powered by the low-voltage battery 20 and DCDC 30, when the power of the low-voltage battery 20 is not enough to supply power to the ECU10, the high-voltage battery 40 is also required to pass through The DCDC 30 charges the low voltage battery 20 .

[0041] In the present invention, in order to reduce the quiescent current consumption of the low-voltage system, the vehicle enters the ultra-low power consumption mode according to the user request. When the use...

Abstract

The invention relates to a vehicle low-power-consumption dormancy control method and control system. The vehicle low-power-consumption dormancy control method comprises the first instruction receivingstep, wherein a dormancy request from the exterior is received; and the first control step, wherein according to the dormancy request, a vehicle is controlled to be in the ultra-low power consumptionmode. The ultra-low power consumption mode refers to a power-saving mode with the lower current during dormancy compared with common vehicles and the current lower than the preset specified value. According to the vehicle low-power-consumption dormancy control method and control system, according to the user request, the vehicle is controlled to be in the ultra-low power consumption mode, the quiescent current power consumption of a low-pressure system is reduced, the charging amount of a low-voltage battery by a high-voltage battery can be reduced, the energy losses of the high-voltage battery can be reduced, and the whole vehicle standby time is prolonged.

Description

technical field [0001] The invention relates to vehicle control technology, in particular to a vehicle low power consumption sleep control method and a control system thereof. Background technique [0002] As the world's environmental protection issues and energy crisis become more and more prominent, it has long been the goal of people to find cars with no pollution or less pollution. Under this background, the future development of new energy electric vehicles has become inevitable. [0003] In the prior art, in the low-voltage system of new energy electric vehicles, DCDC (that is, DC-DC converter) converts the high voltage of the power battery into low voltage to charge the low-voltage battery (such as a 12V low-voltage battery) and supply power to the low-voltage system of the vehicle. [0004] With the trend of electrification, intelligence and interconnection, the static power consumption of electric vehicles has increased significantly, and the low-voltage system of e...
