Detailed description of the invention
Below with reference to Figure of description and specific embodiment, this utility model is described in further details.
As depicted in figs. 1 and 2: the semi-physical emulation platform of a kind of vehicle control unit of electric vehicle, including platform framework 1, platform framework 1 is provided with ignition switch 2, gas pedal 3, brake pedal 4, control switch 5, wherein control switch 5 and include gear on-off, mode switch and cold/hot air-conditioning switch, ignition switch 2, gas pedal 3, brake pedal 4 and control switch 5 connect entire car controller through direct fault location plate 6, the outfan of entire car controller is through direct fault location plate 6 link model controller, the outfan of model controller connects display 7, entire car controller and model controller and PC carry out communication.
Specifically, operator signal includes ignition switch signal, accelerator pedal signal, accelerator pedal signal and shift signal, and these signals provide all through material object, and first these holding wires access direct fault location plate, then access entire car controller; Entire car controller output signal line is then connected to model controller by after direct fault location plate. Model controller adopts Matlab/Simulink to set up Full Vehicle Dynamics model, and Full Vehicle Dynamics model includes motor, battery and vehicle three part, and required data all are from actual parameter. By being compiled into hardware identification code after the integrated bottom layer driving module of MotoHawk, MotoTune it is downloaded in model controller and runs.
As shown in Figure 2: gas pedal 3 and brake pedal 4 are installed on the downside of platform framework, and ignition switch 2, control switch 5 and direct fault location plate 6 are installed on the upside of platform framework 1. Ignition switch signal adopts real automobile ignition switch, ACC, ON and STAR signal can be exported, gas pedal 3 is also adopted by the gas pedal of real vehicle, to export the two-way voltage signal consistent with real vehicle throttle, shift signal is output as double switch amount, take up room to reduce platform, directly adopt three gear on-offs to be simulated. Need one switching value of output and analog signals simultaneously to realize the test of Brake Energy take-back strategy during due to braking, therefore adopt the brake pedal 4 of a belt switch signal to substitute.Another parking brake, charging gun, turn on the aircondition, the signal such as mode switch realizes each through switch. The function of mode switch is identical with gear on-off. Cold/hot air-conditioning switch is for controlling the cold and hot adjustment of air-conditioning.
