Embodiment Construction

[0022] This embodiment is an AMT clutch control system and method for a single-shaft parallel hybrid vehicle, and its power transmission system structure is as follows figure 1 As shown, the main power transmission routes are engine, clutch, permanent magnet synchronous motor, AMT gearbox, transmission shaft to wheels; the vehicle controller HCU controls the coordination of various mechanisms, and the engine and permanent magnet synchronous motor have their own corresponding engine The controller ECU and the motor controller MCU, since the power source of the battery is added to the hybrid electric bus, they correspond to the corresponding battery management system BMS, which can constantly detect the state of charge of the battery. The engine controller ECU, the motor controller MCU and the battery management system BMS all communicate with the vehicle controller HCU through the CAN bus. The communication between the clutch and the automatic transmission AMT and the vehicle c...

Abstract

The invention discloses an AMT clutch control system and method of a single-shaft parallel hybrid electric vehicle. The AMT clutch control system and method are provided for a special structure on a hybrid electric bus, the speed adjusting functions of an engine and a motor during a clutch combining process are fully used, comfort is guaranteed, meanwhile, gear shifting time is shortened, abrasion of a clutch caused by film sliding is lowered, accordingly, the service life of the clutch is prolonged, and the contradiction of the impact degree and film sliding work is effectively resolved. Meanwhile, impact on people during a gear shifting process can be greatly reduced, and the comfort of passengers is improved.

Description

technical field [0001] The invention relates to an AMT clutch control system and method, in particular to an AMT clutch control system and method for a single-shaft parallel hybrid electric vehicle, belonging to the field of hybrid electric vehicles. Background technique [0002] Electromechanical automatic transmission (AMT) is improved on the basis of traditional manual gear transmission; it is an electromechanical-hydraulic automatic transmission that combines the advantages of AT (automatic) and MT (manual); AMT is both The utility model has the advantages of the automatic speed change of the hydraulic automatic transmission, and retains the advantages of high efficiency, low cost, simple structure and easy manufacture of the gear transmission of the original manual transmission. It combines the advantages of the two, and is an electromechanical-hydraulic integrated automatic transmission that is very suitable for my country's national conditions. It is modified on the ...
