Embodiment Construction

[0029] Below in conjunction with accompanying drawing and example the present invention will be further described:

[0030] Such as figure 1 Shown, hybrid electric passenger car cyclic working condition testing system of the present invention comprises:

[0031] The user layer is connected to the CAN acquisition card, and the CAN acquisition card is respectively connected to the motor, engine and clutch of the hybrid electric bus; the user layer also presets the working condition data and basic parameters of the hybrid electric bus and transmits them to the execution layer;

[0032] The execution layer is connected with the controller; the controller is also connected with the CAN acquisition card, and the implementation layer receives the motor, the engine and the actual state information of the clutch of the hybrid bus obtained by the CAN acquisition card from the controller, and according to Preset working condition data and basic parameters, analyze the actual speed of t...

Abstract

The invention discloses a cyclic operation state testing system and method for a hybrid electric bus. According to the cyclic operation state testing system, a user layer carries out selection of operation states to be tracked, connection confirmation of equipment and setting of basic parameters; an execution layer analyzes actual vehicle CAN signals received from a real-time controller according to settings of the user layer, the related parameters, obtained through analysis, of a motor and an engine are used for judgment of the work modes of the hybrid electric bus, and the vehicle speed signals obtained through analysis are used for vehicle speed display; and the real-time vehicle speed analyzed out by the execution layer, the standard operation state vehicle speed to be tracked and the boundary vehicle speed to be tracked are displayed in an oscillogram of a display layer, and meanwhile the equipment connection state, the actual vehicle speed value, the number of times of vehicle speed overrun and the work mode are displayed in real time. Vehicle speed tracking in a standard cyclic operation state test of the hybrid electric bus is realized.

Description

technical field [0001] The invention belongs to the field of testing new energy vehicles, and in particular relates to a testing system and a method thereof for a cycle working condition of a hybrid electric passenger vehicle. Background technique [0002] With the development of society and economy, my country's car ownership and demand continue to grow, and the production and sales of cars rank first in the world. As a national pillar industry, the automobile industry has played a huge role in stimulating employment and improving social benefits; however, the rapid growth of automobile ownership has led to serious energy crisis and environmental pollution problems. In the face of increasingly severe urban smog, PM2.5 emissions and increasingly stringent vehicle energy consumption regulations around the world, the development of new energy vehicles has become an important strategic choice to solve energy and environmental problems. The Chinese government has clearly identi...
