Abstract

The invention relates to a gear engaging clamping stagnation identification and automatic reengaging control method for a synchronizer type gearbox, which comprises the following steps of: controlling a vehicle to start automatic gear engaging, and monitoring gear engaging energy parameters and clamping stagnation type judgment information; gear engaging energy is calculated based on the gear engaging energy parameters; whether clamping stagnation occurs or not is judged on the basis of the gear engaging energy, gear engaging continues when it is judged that clamping stagnation does not occur, when it is judged that clamping stagnation occurs, the clamping stagnation type is judged on the basis of the clamping stagnation type judgment information, and a first reengaging process is executed when it is judged that the clamping stagnation type is the first clamping stagnation type, and executing a second rehanging process when the clamping stagnation type is judged to be the second clamping stagnation type. The invention further relates to a system for executing the gear engaging clamping stagnation recognition and automatic reengaging control method and a vehicle comprising the system.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method and system for gear stuck identification and automatic re gear of a synchronizer type gear box, and a vehicle including the system. Background technology [0002] Synchronizer type gearboxes that use synchronizers to shift gears, such as automatic mechanical gearboxes and double clutch gearboxes, often get stuck in gear due to the locking of top teeth and synchronous rings, resulting in gear failure, and even overload failure of synchronizer control mechanism in some extreme cases, so that the automatic gearbox cannot shift successfully, resulting in the loss of power of the vehicle. At present, the problem of gear clamping is mainly solved by simple automatic re hanging mode or by changing the structure of synchronizer (for example, changing the shape of meshing teeth of synchronizer). The success rate of simple automatic re engagement is not high, while the cost of changing the sync...
