Electric control unit test method and device

Abstract

The invention discloses an electric-controlled unit testing method and apparatus. A model loading and process amount monitoring unit is connected to a model run unit for transmitting the parameter model of the dynamic assembly system to the model run unit, the model run unit is circularly connected to an electric-controlled unit, the model run unit produces operating parameters and transmits them to the electric-controlled unit, the electric-controlled unit generate PWM control signals and transmits them back to the model run unit, a sensor parameter testing and capturing unit is connected with the electric-controlled unit for recording the operating parameter value and transmitting instruction of modifying operating parameter value to the model run unit, and an on-line proving unit is connected with the model run unit for modifying operating parameter value. Adopting the inventive technical scheme can combine the actual electric-controlled unit and the simulation model as a closed-loop testing system, which achieves the goal of testing the electric-controlled unit accurately and safely with high-efficiency and low cost.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a testing method and device for an electronic control unit. Background technique [0002] The testing of electronic control units is traditionally carried out by bench or vehicle test, which has many disadvantages. The powertrain system must be manufactured before the initial development of the electronic control unit. The development of the powertrain system and the development of the electronic control unit are a series of development methods; It is difficult to test. If in order to test these working conditions, the entire test system must be placed in this extreme test environment, which makes the cost of the test very high; in addition, the newly developed program has not been verified in terms of logical structure and algorithm. Therefore, when carrying out bench test experiments, there are many uncertain factors that may damage the system equipment or even threaten th...

The powertrain system must be manufactured before the initial development of the electronic control unit. The development of the powertrain system and the development of the electronic control unit are a series of development methods; It is difficult to test. If in order to test these working conditions, the entire test system must be placed in this extreme test environment, which makes the cost of the test very high; in addition, the newly developed program has not been verified in terms of logical structure and algorithm. Therefore, when conducting bench test experiments, there are many uncertain factors that may damage the system equipment or even threaten the safety of the experimenters.
