Abstract

The invention provides a vehicle timely four-wheel drive system mode switching method, which comprises the following steps: acquiring vehicle driving information in real time, and uploading the vehicle driving information to a vehicle body electronic system; receiving a current mode, a mode request and a 4L mode switching state signal acquired by a main control module, and judging whether an N-gear locking function needs to be triggered or not before switching into the 4L mode or switching out of the 4L mode is not completed; according to the vehicle driving information, judging 4L mode switching; identifying the current road condition of the whole vehicle according to the driving information of the vehicle and a state signal acquired by the main control module, and prompting a user to select a four-wheel-drive system mode through a four-wheel-drive system mode change-over switch; wherein the four-wheel drive system modes comprise a 2H mode, a Lock mode, a 4L mode and an AUTO mode.

Description

Technical field [0001] The present invention relates to the field of automotive technology, and more particularly to an automotive timely four-wheel drive system mode switching device and method. Background technique [0002] With the favorable application of the automatic switching of two-drive and four-wheel drive technology, the requirements of the mode switching control method of the time-time four-wheel drive system are also increasingly high, and therefore, the present invention is based on this demand. A control method for automotive timely four-wheel drive system mode switching is proposed. [0003] In the prior art, the four-wheel switch control selection is more, usually one switch, which is very inconvenient during mode switching, and has certain limitations for functional expansion; and prior art Cut the low speed four-wheel drive (4L) or cut from the low speed four-wheel drive mode, the driver suddenly hangs an N-file driving, which can cause the inner shift lever in...
