Embodiment Construction

[0031] For powertrain components such as motors, generators, and inverters, HCU needs to control them through hard-wired signals in order to start and run normally. Usually, the connection between the HCU and the powertrain components on the hard wire is mainly divided into two modules, one is the high-side driver module, and the other is the low-side driver module. Wherein, the high-side driving module includes high-side driving pins, and the low-side driving module includes low-side driving pins. The high-side driver module is used to output a high-level signal, and the low-side driver module is used to output a low-level signal. The powertrain components are connected to the high-side drive pin or the low-side drive pin according to their respective trigger requirements. When the powertrain component is not started, the high-side drive module or the low-side drive module connected to it sends a power-on signal to the powertrain component to start, and after the powertrain ...

Abstract

The embodiment of the invention discloses a power assembly control method, a power assembly control device and a power assembly control system. The power assembly control method comprises the following steps that an assistant controller acquires a first message which is sent to the assistant controller by a power assembly component; and if the assistant controller judges that the power assembly component does not have a fault according to the first message, and the assistant controller does not receive any message from the power assembly component within a preset time period after receiving the first message, and does not detect a work stop command sent to the power assembly component by a hybrid power controller within the preset time period, the assistant controller sends a start signal to the power assembly component so as to enable the power assembly component to further work. The power assembly control method, the power assembly control device and the power assembly control system are capable of realizing the purpose that the power assembly component can still operate normally under a condition of HCU output pin fault.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a powertrain control method, device and system. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] A hybrid electric vehicle (Hybird Electric Vehicle, referred to as HEV) is a vehicle that uses two or more power sources, and the common power sources are divided into two types: an engine and a motor. The core of a hybrid vehicle is a hybrid system, which includes a hybrid controller (Hybird Control Unit, HCU for short), an engine, an electric motor, a power battery, a clutch, and the like. Among them, the hybrid power controller is the core component of the hybrid power system, which is used to control and coordinate other components of the hybrid power system. plays a k...
