The invention discloses a vehicle climbing control method and system, a dual-clutch transmission and a vehicle with the dual-clutch transmission. The method comprises the steps that whether the vehicle is in an uphill mode or not is judged when the vehicle is started on a slope; in the uphill mode, a request instruction for increasing the idle speed is sent to an engine controller according to the gradient, the air inlet temperature of an engine and the gear of the vehicle; when the rotating speed of the engine is in the flameout risk rotating speed area, the torque limiting function of the clutch is activated; and releasing the torque limit of the clutch when the engine leaves the flameout risk rotating speed area. The invention provides a vehicle-mounted climbing control method and system, a dual-clutch transmission and a vehicle with the vehicle-mounted climbing control method and system, and aims at carrying out climbing control on a small-torque engine carried by dual clutches or an engine with insufficient idle speed capability, so that the required torque of the clutches can be reasonably calculated, and the reasonable torque transmission of the clutches is ensured; and the problems of engine rotating speed reduction and even engine flameout cannot be generated.
本发明公开了一种车辆爬坡控制方法、系统、双离合变速器及其车辆,包括:在坡路起步时判断车辆是否处于上坡模式;在上坡模式中,根据坡度大小、发动机进气温度并结合车辆所处挡位,向发动机控制器发送提升怠速转速的请求指令;当发动机转速处于熄火风险转速区内,激活离合器的扭矩限制功能;发动机离开熄火风险转速区,解除离合器的扭矩限制。本发明提出了一种车载爬坡控制方法、系统、双离合变速器及其车辆,针对双离合器搭载小扭矩发动机或者怠速能力不足的发动机进行爬坡控制,可以保证合理的计算离合器需求扭矩,保证离合器合理的扭矩传递,不会产生发动机转速拖低甚至发动机熄火的问题。
