Abstract

The invention relates to a gear shifting method and device of an automatic gearbox, a storage medium, electronic equipment and a vehicle, is applied to pure electric heavy trucks and aims to solve the technical problems that an existing two-parameter gear rule is high in power consumption and low in motor working efficiency in the actual running process of the vehicle. The method comprises the following steps: determining an initial target gear of the automatic gearbox according to a two-parameter gear rule in response to acquired state information and driving environment information of the vehicle; determining a first comparison relation between the no-load acceleration and the load acceleration of the vehicle according to the state information and the driving environment information; and according to the current opening degree of an accelerator pedal of the vehicle, the first comparison relation and a second comparison relation between the current gear of the automatic gearbox and the initial target gear, adjusting the initial target gear, obtaining a final target gear, and switching the automatic gearbox to the final target gear from the current gear.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a gear shifting method, device, storage medium, electronic equipment and a vehicle of an automatic transmission. Background technique [0002] With the continuous progress of new energy vehicles in the field of commercial vehicles, their use has also begun to extend to different application scenarios. Among them, pure electric heavy trucks have received more and more attention due to their quiet operation and zero exhaust emissions. [0003] At present, pure electric heavy trucks are mainly used to meet short-distance transportation needs, mainly serving coastal ports, large logistics parks, mining areas and other places. However, pure electric heavy-duty trucks are more sensitive to power consumption due to limited power, vehicle weight, and large daily average transportation distance. The existing gear shifting strategies are more based on the two parameters of...
