Problems solved by technology
[0008] However, the above power control system only considers the response strategy when a single power component fails during the control process, and does not consider the operation of other power components, resulting in unsatisfactory power control effects
[0009] In addition, the power control systems in the prior art are usually only applicable to vehicles of one power type, for example, only applicable to parallel hybrid systems, or only applicable to series hybrid systems. In addition, the above-mentioned power control systems are usually only applicable to For vehicles with one power source, for example, it is only suitable for vehicles with capacitors as the power source or vehicles with battery packs as the power source
In a word, the power control system of the hybrid electric vehicle in the prior art has a small scope of application and poor portability

The invention discloses a power control system for a hybrid vehicle. The power control system comprises a detection device (11) and a control device (12). The detection device (11) is used for detecting the failure information of a power system of the vehicle. The control device (12) is provided with a coordination processing module (121) for outputting a control command to other power parts according to the failure information of at least one power part in the power system to enable the vehicle to run normally. The input end of the coordination processing module (121) is connected with the detection device (11), and the output end of the coordination processing module (121) is connected with the power system. According to the power control system, the possible influence of failures of each power part on the other power parts is taken into account, and the running states of the other parts are controlled to realize coordination control over different power parts, so that the power system can run normally under a failure condition. The invention also provides a power control method corresponding to the power control system. By the power control method, the same effects are achieved.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a power control system and a power control method for a hybrid vehicle. Background technique [0002] For hybrid vehicles, it usually includes a power system and a power control system. The power system includes power components such as an engine, a gearbox, a motor, and a battery. The power control system realizes fault identification and fault management by detecting and controlling each power component. and fault handling to ensure the normal operation of the vehicle under fault conditions. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a power control system of a hybrid vehicle in the prior art. [0004] like figure 1 As shown, the power control system of a hybrid vehicle in the prior art includes a detection device 11' and a control device 12', the detection device 11' includes an engine detection component, a gearbox detection comp...
