Problems solved by technology

However, these design studies either have high development costs, or cannot perform safe and reliable torque control on hybrid electric vehicles, and have the following disadvantages:
The cycle of this development method is long, the cost is very high, and it is not convenient for the variant design of hybrid electric vehicles
[0012] Most of the research on the design of hybrid electric vehicle powertrain control system mainly focuses on the functional development of the control system, and has not yet involved the field of safety monitoring and fault handling system design

Embodiment Construction

[0024] The framework of the torque control safety monitoring system of the hybrid electric vehicle of the present invention can be referred to as shown in Figure 1, including,

[0025] The functional layer generates various control signals of the hybrid electric vehicle powertrain, including a driver demand module, a torque distribution module, an engine torque control module and a motor torque control module. The driver demand module receives the driver power demand signal and converts converting the driver power demand signal into a driver torque demand signal, which is then transmitted to the torque split module, which converts the driver torque demand signal into an engine torque demand signal signal and the motor torque demand signal, and transmit them to the engine torque control module and the motor torque control module respectively, and the engine torque control module controls the engine work according to the engine torque demand signal, and provides Torque output, t...

Abstract

The system of safe torque monitor for mixed power automobile is one four layer structure including one functional layer for completing various controls, one limiting layer for limiting the extreme values of functional layer signals, a redundant monitoring layer for detecting the functional layer signals and one physical detection layer for detecting the normal operation of the memory areas and the program flows. The present invention can control the output torque of the mixed power automobile and monitor the operation state of the power units to raise the safety and reliability of the mixed power automobile. The present invention also discloses one kind of safe torque monitoring system for mixed power automobile, and the system includes an engine controller module, a multiple power source controller module, a motor controller module, etc and can raise the reliability of mixed power automobile.

Description

technical field [0001] The invention relates to a torque control system architecture of a hybrid electric vehicle, in particular to a torque control system architecture of a hybrid electric vehicle with a safety monitoring function; the invention also relates to a torque control safety monitoring system of a hybrid electric vehicle. Background technique [0002] Energy crisis and environmental degradation are two major issues affecting global development today. Research and development of energy-saving and low-emission vehicles can effectively alleviate energy pressure and improve environmental quality. Hybrid vehicles have the advantages of low fuel consumption, low emissions, long mileage, and mature technology. They are currently the most feasible energy-saving vehicles that can be mass-produced. [0003] A hybrid vehicle combines an engine, a motor, and an energy storage device (battery). The good matching and optimal control between them can give full play to the advant...
