Document Type and Number:
WIPO Patent Application WO/2023/131292
Kind Code:
A1
Abstract:
A control method and apparatus for a transmission of a new energy vehicle, a vehicle, and a storage medium. The method comprises: when not detecting transmission gear information from prior to the previous vehicle dormancy, and when gear self-learning fails after not detecting the transmission gear information from prior to the previous vehicle dormancy, obtaining a current logic gear of the vehicle and the current depth of an accelerator pedal being depressed, and receiving a current transmission fault signal and a current transmission controller state signal sent by a transmission controller; and if the current logic gear is a forward gear or a reverse gear, if the current depth of the accelerator pedal being depressed is greater than a preset depth threshold, if the transmission does not have a first preset fault currently, if the transmission controller does not have a second preset fault currently, and if the transmission gear information from prior to the previous vehicle dormancy is still not detected currently, controlling the transmission to perform emergency upshifting. In the control method, when a user has a need to move urgently and the vehicle meets an emergency upshifting condition, the vehicle can move urgently, thereby meeting the user's need to move urgently.
