Abstract

The invention provides a vehicle control method. The vehicle control method comprises the steps that when an engine drives a vehicle to run through two clutches, whether gear shifting conditions are met is judged, and if yes, the current first output ends or second output ends connected with the input ends of the two clutches are controlled to be separated; when the first output ends or the second output ends connected with the input ends of the two clutches are separated until reaching sliding friction points, an ISG motor is controlled to drag the engine to carry out rotation speed adjustment, and a drive motor is controlled to improve output torque to maintain the drive force needed by the vehicle according to the torque requirement of the vehicle; when the current rotation speed of the engine is within the target rotation speed adjustment range, the current second output ends or the first output ends separated from the input ends of the two clutches are controlled to be connected with the input ends of the two clutches to achieve gear shifting. The vehicle control method has the advantages that gear shifting time is short, gear shifting smoothness is high, and the two clutches are long in service life. The invention further provides a vehicle control system and a vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle control method, a control system and a vehicle with the control system. Background technique [0002] Traditional fuel vehicles can improve the fuel economy and comfort of the vehicle by using dual clutch transmission DCT (Dual Clutch Transmission), automatic transmission AT (automatic transmission) and multi-gear transmission. However, for hybrid vehicles, The addition of the electric drive system leads to space arrangement problems and a reduction in the energy-saving contribution of the transmission. Therefore, a transmission with fewer gears is usually designed to solve the layout problem of the power system and reduce the cost of the transmission. [0003] The control method adopted by DCT in the shifting process is: when the transmission control unit TCU detects that it is necessary to shift gears, gradually reduce the control oil pressure of the clutch in th...
