Abstract

The invention discloses a gear shifting device. The gear shifting device comprises a synchronizer, a shift gear, a parking gear, a driving mechanism and a controller. The synchronizer is arranged between the shift gear and the parking gear and further comprises an engagement mechanism. The driving mechanism is used for driving the engagement mechanism to move. The engagement mechanism is engaged with the shift gear or the parking gear. The controller is electrically connected with the driving mechanism and further used for controlling the driving mechanism to execute gear shifting operations according to instructions of operators. The invention further discloses a gear shifting method based on the gear shifting device and a vehicle with the gear shifting device. According to the gear shifting device, the gear shifting method and the vehicle, parking is contained into gear shifting to achieve integrated control, and advantages are obtained on the aspects of concise control, convenient calibration and the like; control strategies are made more reliable; cost is reduced; and expandability and portability are achieved.

Description

technical field [0001] The invention relates to a shifting device, in particular to a shifting device applied to a synchronizer, a shifting method of the device and a vehicle with the device. Background technique [0002] Shifting refers to the process of switching the vehicle between various gears; parking is to give the vehicle a resistance when the vehicle needs to stop, so that the vehicle does not slip. Regardless of whether it is a traditional fuel vehicle or a current new energy vehicle, since shifting and parking are carried out by two sets of special transmission chains, it is necessary to configure a separate set of controls for the shifting function and parking function. logic to control. This leads to problems such as redundancy of the control device. [0003] In addition, in the existing new energy vehicles, when the engine and generator in the hybrid electric drive device are switched in series and parallel, the clutch is used as a driver to realize the engag...
