Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing:

[0022] like figure 1 As shown, the weak hybrid engine 1 of the weak hybrid engine reliability test system is installed on the flat plate 6 through the engine tooling 3 and the support 8, and the output of the engine 1 is connected with the dynamometer 5 through the transmission shaft 4, Constitute a mechanical bench. Starter 15 is installed on the engine tooling 3, and when working, its driving gear is meshed with the engine flywheel ring gear 2, drives engine operation, starts engine.

[0023] The accelerator actuator 7 is connected with the accelerator pedal 11 through the actuator, and controls the stepping and lifting of the accelerator pedal 11. The accelerator pedal 11 converts the pedal opening into an electrical signal and inputs it to the engine ECU 12. After the engine ECU 12 detects the accelerator pedal opening, it controls the engine. output torque. The work...

Abstract

The invention discloses a reliability test system for a mild hybrid power engine. The system is characterized in that: the mild hybrid power engine 1 is connected with a flat plate 6 through an engine tool 3 and a support 8; the engine tool 3 is connected with a dynamometer 5 through a transmission shaft 4 to form a mechanical stand; a throttle actuator 7 controls an accelerating pedal 11 to input an accelerating pedal opening signal for an engine ECU12; a brake vacuum pressure sensor 16 is connected with an engine inlet manifold through an air pipe 17, and a vacuum degree signal is input to the engine ECU12; the engine ECU12 is connected with a starting relay 14 through a starting control wire 13 so as to control the work of a starter 15; and dSPACE 9 is connected with the engine ECU12 through a signal processor 10 for simulating complete vehicle gear, clutch, speed, and other signals for the engine ECU12. The system can simulate idling start-stop working environment of the engine. Therefore, the idling start-stop function of the mild hybrid power engine on the stand is realized, and the automatic simulating control is realized through the dSPACE 9 so as to perform the reliability test on the mild hybrid power engine.

Description

technical field [0001] The invention belongs to the field of automobile testing, and in particular relates to a reliability test system for a weak hybrid engine. Background technique [0002] As the world pays more and more attention to the environmental protection of automobiles, weak hybrid electric vehicles are also born. The starter will automatically start the engine, thereby reducing fuel consumption and emissions during the idling phase of the vehicle, and achieving the purpose of energy saving and environmental protection. However, the weak hybrid engine will be tested on the bench to realize the idle start-stop function, and no relevant technology has been retrieved before the present invention. Contents of the invention [0003] When the weak hybrid engine is starting and stopping at idle speed, the engine ECU will detect the corresponding starting and stopping conditions, and the starting should meet all the following conditions: 1) The engine is in a stopped s...
