In order to test and verify the control strategy and CAN communication of SCR Adblue dosing pump, we establish a co-simulation model based on CANoe and Simulink, in which, the simulation analysis of the dosing pump nude and OBD is carried out, and the correctness of the control strategies and CAN communication of the dosing pump is verified. In addition, the design of the drive program and CAN communication program is improved in accordance with the simulation results.
