2results about How to "Reduce shift shock" patented technology

This invention discloses a vehicle control method, device, equipment, and storage medium, comprising: acquiring current vehicle driving information; determining resistance information based on the driving information; determining the total output torque demand based on the driving resistance information; and controlling the current vehicle according to the total output torque demand; wherein the current vehicle is a dual-electric drive axle four-motor system. Using this method, the output torque demand of the dual-electric drive axle four-motor system is obtained through driving information, and the actuator and its torque magnitude are determined based on the torque demand. This achieves the effects of balancing drivability and power, reducing shift frequency, reducing shift shock, reducing shift time, and eliminating power interruption during shifting.

The utility model provides a tractor electric drive power system, including motor module, input module, variable speed module that transmits connection in proper order, variable speed module includes intermediate shaft with input module through the clutch connection, the gear shift tooth cover of slidable assembly along the axle direction on intermediate shaft, rotatable assembly on intermediate shaft gear position drive gear set, gear position driven gear set and gear position drive gear set with gear position drive gear set mesh with output shaft, and the number of intermediate shaft is at least two, and the gear shift tooth cover is combined with gear position drive gear set and forms the connection of intermediate shaft and output shaft along the axial sliding, the utility model improves the high efficiency interval coverage rate of motor, reduces energy consumption, avoids the tooth shaft damage among variable speed module under the sudden situation such as motor out of control, improves transmission safety, and reliability, avoids the power interruption of gear shifting, and reduces the gear shifting impact, improves the scene adaptability of electric drive power system, reduces energy and hardware loss.
