Automatic calibration of new energy vehicular operation mode switchover method based on bus road condition

This paper introduces an automatic calibrated pure electric (EV) mode of automatic switching based on bus road conditions. The entire vehicular control system collects bus road spectra using specific methods, identifies if the direction of the bus is along the predetermined bus lane, and records the positions where the driver manually switches the model, to finally implement an automatic EV switchover method function along bus lane roads. This method enables the flexible calibration of roads where EV mode is to be used, and implements automatic switching to avoid running on uphill roads in EV mode in order to decrease the labor intensity of drivers.
