Description
technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a signal simulation device and a powertrain electronic control development platform using the signal simulation device. Background technique [0002] As we all know, the power of a car is good or bad, first of all depends on the power of the engine. Therefore, in the process of engine research and development, it is necessary to carry out all-round simulation trial production for structural design and control system. In particular, the electronic control unit (ECU) of the automobile engine is the core of the automobile engine control system. The performance (power, economy, emission) reaches the best. [0003] Obviously, it is one of the key procedures of simulated trial production to carry out simulation tests of control strategies under different working conditions for engines with a certain structure. [0004] The above simulation test is carried out on the p...
