Title:
GEAR SWITCHING CONTROL METHOD AND APPARATUS, ELECTRONIC DEVICE, MEDIUM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/262685
Kind Code:
A1
Abstract:
The present disclosure relates to a gear switching control method and apparatus, an electronic device, a medium, and a vehicle. The gear switching control method is applied to a DCT, the control method comprising: when a current gear is the reverse gear and if a control instruction for instructing to switch to the drive gear is received, then controlling a DCT to switch to second gear. As such, when the DCT is switched from the reverse gear to the drive gear, the DCT is directly controlled to switch to second gear. Since the reverse gear of the DCT achieves power input by means of an odd-number axle and second gear achieves power input by means of an even-number axle, thus when the gear is switched, a clutch of the even-number axle can be controlled to be engaged while a clutch of the odd-number axle is disengaged, so that the DCT is directly switched from the reverse gear to second gear, avoiding power interruption, thereby reducing the possibility of a vehicle rolling down a slope.
