Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0035] The present invention proposes a method for statically simulating engine dynamics to detect the input / output of engine electronic control unit components based on the working characteristics of each electronic control unit, and designs a specific engine electronic control system component function test system.

[0036] Such as figure 1 , 2 As shown, the system includes a trolley case 1. A detection panel 18 is fixed inside the trolley case 1. A compressed air pump 20, an electronic control unit ECU19 and a power cord socket 2 connected to the electronic control unit ECU19 are arranged on the detection panel 18. , 220V power switch 3, 24V power switch 16, potential knob 17, EPR system port 5, low-voltage solenoid valve port 6, exhaust gas control valve port 7, electronic throttle port 8, oxygen concentration sensor port 9, DEPR system port 54 and OBD A system ...

Abstract

The invention provides an engine electric control system component function testing system which comprises a draw-bar box. A detection panel is fixed into the draw-bar box. A compression air pump, an electronic control unit (ECU), a power line spigot connected with the electronic control unit (ECU), a 220V power supply switch, a 24V power supply switch, a potential knob, an EPR system interface, a low-pressure electromagnetic valve interface, a waste gas control valve interface, an electronic throttle valve interface, an oxygen concentration sensor interface, a DEPR system interface and an OBD system interface are distributed on the detection panel. The OBD system interface is externally connected with a PC terminal through a CAN communication diagnosis harness. The method includes the step that a static simulated engine dynamically detects input and output of an engine electric control unit component. The system and the method have the advantages that operation environment of an electric control unit is simulated through combination of software and hardware, the operating state of the electric control unit is monitored through the software so that whether the electric control unit breaks down can be judged, the structure is simple, cost is low, moving is flexible and operation is convenient to carry out.

Description

technical field [0001] The invention relates to the technical field of automobile engines, and relates to a detection device and a detection method for functional detection of components of an engine electronic control unit. Background technique [0002] At present, there are mainly two ways to test the components of the electronic control unit of the automobile engine: one is to test through the engine bench or the whole vehicle, and the other is to use the simulation test device to carry out the simulation test. The engine bench test is to place the electronic control unit on the actual engine bench, and all the inputs and outputs of the electronic control unit are measured data. However, the bench test has high cost and poor flexibility, so it is not suitable for the detection of batch ECU components. Therefore, it is necessary to design a device that can simulate the function of the engine bench and perform function detection when it is far away from the engine. Conte...
