Step B7, if the driver does not operate after hearing the prompt tone but the rotating speed is higher than the calibration value, the speaker broadcasts the prompt voice with the over-high rotating speed to remind the driver to quit the auxiliary gear shifting mode;

and step B8, in the auxiliary gear shifting process, the driver steps on the clutch or the brake, and the loudspeaker reports the voice prompt corresponding to the pedal exit.

In the auxiliary gear shifting process, if the driver steps on the clutch, the loudspeaker broadcasts a voice prompt of clutch pedal withdrawal, and if the driver steps on the brake, the loudspeaker broadcasts a voice prompt of brake pedal withdrawal.

Wherein, intelligence shift controller 1 and instrument 3 pass through CAN bus connection, shift button 2 with speaker 4 pass through the wire with 1 electric connection of intelligence shift controller. Specifically, the shift button 2 is disposed on the shift handle, the meter 3 is independent from the vehicle meter or integrated in the vehicle meter, and the speaker 4 is independent from the vehicle speaker or integrated in the vehicle speaker, which is not specifically limited in the present invention, and preferably, the meter 3 is independent from the vehicle meter and the speaker 4 is independent from the vehicle speaker.

According to the gear shifting auxiliary man-machine interaction system provided by the embodiment of the invention, the gear requirement of a driver is accurately obtained through the gear shifting button, meanwhile, rich voice prompt is carried out through the loudspeaker, the current system state of the driver is told in real time, so that the driver can complete gear shifting operation step by step according to guidance, therefore, by increasing information interaction between the gear shifting button and the loudspeaker and the driver, the semi-automatic gear shifting target that the driver does not step on a clutch for gear shifting is realized under the condition that the cost is not increased greatly, and the loudspeaker can give a prompt under different working conditions, particularly when the driver operates abnormally; richen driver's mutual information, agree with the location of intelligent car more, alleviate driver's operation burden.

Thus, various embodiments of the present disclosure have been described in detail. Some details that are well known in the art have not been described in order to avoid obscuring the concepts of the present disclosure. It will be fully apparent to those skilled in the art from the foregoing description how to practice the presently disclosed embodiments.
