Problems solved by technology

When an existing vehicle breaks down, it either needs to be repaired before it can continue to work; or the vehicle sacrifices some functional devices, such as air conditioners, charging ports, etc., so that the vehicle can run normally, which leads to poor driving experience of the vehicle

Embodiment

[0062] See figure 1 , figure 1 It is a flow chart of a fault handling method implemented according to the present invention, and the fault handling method is applied to a hybrid vehicle.

[0063] Such as figure 1 As shown, the fault handling method specifically includes the following steps:

[0064] S100: Obtain the running status of the engine power system and the high-voltage system of the target vehicle.

[0065] In some implementations, the engine power system includes an engine, an engine controller, an engine power output shaft, a fuel tank, and other components that are output from the engine power; the high-voltage system includes a high-voltage motor, a power battery, a high-voltage wire harness, an inverter, PDU, DCDC converter, power motor and high-voltage end accessories and other components that circulate high-voltage electricity.

[0066] It is understandable that for hybrid vehicles, there are two sets of power systems, which are the power system composed of...

Abstract

The invention discloses a fault handling method for a hybrid vehicle. The fault handling method includes: acquiring the operating states of the engine power system and the high-voltage system of the target vehicle; Judging whether the target vehicle is faulty; if the target vehicle is faulty, then if the target vehicle is faulty, start the engine and control the corresponding accessory equipment to work according to the remaining power of the target vehicle. The invention also discloses a fault processing device, a vehicle with the device and a computer storage medium. By adopting the invention, the functions of the vehicle can be maintained as much as possible under the premise of ensuring the safety of the occupants and the vehicle, so that customers can obtain better use effects.

Description

technical field [0001] The present invention relates to a vehicle fault processing method, in particular to a fault processing method applied to a hybrid vehicle, and also to a fault processing device and a vehicle with the fault processing device. Background technique [0002] With the continuous development of hybrid technology, hybrid vehicles are becoming more and more complex. Because a hybrid vehicle has both a traditional internal combustion engine power system and a high-voltage system, and the two systems are highly coupled together. When a vehicle breaks down, how to perfectly control the traditional power system and high-voltage system to protect the safety of the occupants and the vehicle becomes a difficult problem. When an existing vehicle breaks down, it either needs to be repaired before it can continue to work; or the vehicle sacrifices some functional devices, such as air conditioners, charging ports, etc., so that the vehicle can run normally, which leads...
