Abstract

The invention discloses an automatic gearbox torque pre-control and shift coordination control method, device and automobile. This method optimizes the control logic. If the torque pre-control and shift control are not triggered at the same time, the gearbox will perform normal torque pre-control; The engine torque intervention is carried out during the process, and when the engine torque is stable, the torque pre-control control is exited and the subsequent shift control is entered. The present invention has already completed the clutch oil filling in the torque pre-control, increases the intervention of the engine torque, ensures that both the clutch torque and the engine torque remain stable during the torque pre-control, and proposes a new method when simultaneously triggering shifting and torque pre-control The new strategy, in the process of torque pre-control, the clutch that is about to be combined is controlled by oil filling, which reduces the subsequent shift time, and also avoids the shift shock caused by torque fluctuations when the torque pre-control directly enters the shift control.

Description

technical field

[0001] The present invention relates to a coordinated control method in the technical field of automobile control, in particular to an automatic transmission torque pre-control and gear shift coordinated control method, and also relates to an automatic transmission torque pre-control and gear shift coordinated control device, and also relates to A hybrid car. Background technique

[0002] A hybrid vehicle (referred to as a hybrid vehicle) refers to a vehicle equipped with two or more power sources. Currently, hybrid vehicles mainly refer to gasoline-electric hybrid vehicles. The power source is mainly an engine, but those with a motor as the engine Auxiliary power drives the car, and the two combine to save energy.

[0003] Hybrid vehicles equipped with wet dual-clutch automatic transmissions are widely promoted because of their fast and smooth shifting, strong power, and high transmission efficiency. In the prior art, when the battery capacity of the vehic...
