sb5, starting a temperature adjusting module, and reducing the temperature of the cab;
sb6, starting timing, detecting the temperature of the cab again when the set first time value is reached, and determining whether the temperature is lower than a second set value, if yes, going to step Sb2, and if no, going to step Sb 7;
sb7, entering an auxiliary driving mode, driving the vehicle by a driver, and assisting the driver to control the vehicle by the intelligent driving system;
sb8, enter autonomous driving module, autonomously drive vehicle by driver.
5. The intelligent driving method according to claim 4, wherein step S2 further comprises the steps of:
sb9, after entering an autonomous driving mode, acquiring a face image signal of a driver, and simultaneously starting timing and recording driving time;
sb10, when the set second time value has elapsed, acquiring the face image signal of the driver again, comparing the latest acquired face image signal with the previous face image signal, determining whether the acquired face image signal is the same driver, if yes, proceeding to step Sb11, if no, returning to Sb10 for re-determination;
and Sb11, entering an auxiliary driving mode and giving out a warning signal to continuously remind a driver of stopping for a rest.
