Abstract

The invention provides a starting control method and system for a vehicle and the vehicle, and relates to the technical field of engines of vehicles. The starting control method comprises the steps ofcollecting a pressure value of a brake master cylinder of the vehicle or the longitudinal acceleration of the whole vehicle in real time; judging whether a driver of the vehicle has a starting intention or not according to the pressure value of the brake master cylinder or the longitudinal acceleration of the whole vehicle; and if so, enabling the engine to reserve a compensation torque. The starting control method provided by the invention can realize stable starting.

Description

Technical field[0001]The present invention relates to the technical field of vehicle engines, in particular to a starting control method, system and vehicle for a vehicle.Background technique[0002]Under normal circumstances, during the starting process of an automatic transmission car, due to the load impact generated by the coupling of the clutch, it will cause the drop or fluctuation of the engine speed, cause the shock or shaking of the whole vehicle, and have a negative impact on the starting quality and the user's driving experience. .[0003]Conventional solutions are generally optimized through two aspects: one is that the transmission control unit controls the coupling speed of the clutch to reduce the impact of load intervention; the other is that the engine control unit increases the air intake to obtain stronger idle speed adjustment ability. But these two schemes have their drawbacks. Slowing down the clutch engagement speed will slow down the starting speed and weaken the...
