Problems solved by technology

[0003] The traditional engine speed signal simulation system uses a belt drive between the crankshaft signal plate and the camshaft signal plate. However, due to the inherent shortcomings of the belt drive, the transmission ratio is not accurate, so the correctness of the software algorithm cannot be effectively verified.

Abstract

The invention relates to a shaft transmission-based engine rotation speed signal simulation system, which comprises a mounting seat, and a driving mechanism, a crankshaft signal disk, a camshaft signal disk, a crankshaft rotation speed sensor and a camshaft rotation speed sensor arranged on the mounting seat, wherein the crankshaft rotation speed sensor and the camshaft rotation speed sensor are arranged on side surfaces of the camshaft signal disk and the crankshaft signal disk correspondingly. The system also comprises a transmission shaft. The driving mechanism is connected with the transmission shaft; both the crankshaft signal disk and the camshaft signal disk sleeve the transmission shaft and are fixedly connected with the transmission shaft respectively; the driving mechanism drives the transmission shaft to rotate to further drive the crankshaft signal disk and the camshaft signal disk to rotate synchronously; and the crankshaft rotation speed sensor and the camshaft rotation speed sensor detect rotation speed signals of the crankshaft signal disk and the camshaft signal disk respectively. Compared with the prior art, the shaft transmission-based engine rotation speed signal simulation system has the advantages that the structure is simple; the precision is high; the simulation result is closer to an actual condition and the like.

Description

technical field [0001] The invention relates to an engine speed signal simulation system, in particular to an engine speed signal simulation system based on shaft transmission. Background technique [0002] As the structure and control strategy of the engine electronic control system become more and more complex, the difficulty of research and development of the electronic control system and the workload of experiments have greatly increased, and the cost has also increased significantly. The V-type development model has become the mainstream of the engine electronic control unit (ECU) development process. In order to cooperate with the development of ECU software, it is necessary to use the hardware simulation environment to simulate the working state of the engine to verify the correctness of the software algorithm. The engine speed signal is an important signal of the working state of the engine. The specific phase relationship information of the engine crankshaft and cam...
