Abstract

The invention provides a simulation test device and a simulation test method for an electronic control unit (ECU) of an engine. The simulation test device comprises a main control chip unit, a power module, a BDM unit, an ECU power control unit, an ECU voltage test unit, an over-current protection unit, a sensor analog quantity generating unit, an on / off value digital signal generating unit, an ECU inductance-outputting executive component simulation load and protection unit, an ECU resistance-outputting simulation load unit, a communication unit and a signal wiring harness, wherein each unit is connected with the main control chip; and the power module supplies power to each unit. The method for detecting by simulating an external signal connected by the stimulation ECU and by driving an input / output interface having common property with the ECU is based on the performance characteristic of the ECU and suitable for detecting simulation function of a plurality of ECU large-scale production. The method has the advantages of simple structure, low cost, convenient movement, convenient test and the like.

Description

technical field [0001] The invention relates to the field of engine electric control, and relates to a simulation detection device and a detection method for performing functional inspection on an engine electric control unit ECU. Background technique [0002] The automotive engine electronic control unit is a complex on-board computer controller. At present, the detection of the electronic control unit ECU is mainly carried out through the engine bench and the simulation inspection device. Bench testing puts the electronic control unit on the actual engine bench, and all the input and output of the electronic control unit are directly connected with the relevant parts of the engine. All the data are collected and measured data, which can completely test the ECU. performance. However, for large-scale ECU production, bench testing is obviously neither economical nor convenient. Therefore, it is very necessary to design a device that can simulate all the functions of the en...
