The invention discloses a ramp assist function self-adaptive control method and system for an automatic shift commercial vehicle, and the main design concept of the method is as follows: reading current vehicle speed information, gradient information, accelerator brake pedal information, transmission gear information and ramp assist function working condition information; whether the ramp assist function is activated or quitted or not is automatically recognized, besides different load weight conditions, manual activation or release judgment is not needed, manual operation (for example, a ramp assist switch is turned on) is not needed, the vehicle can be normally started and driven after being ignited, and the ramp assist function can be activated and quitted in a self-adaptive mode. And the defect that the auxiliary function of the flat road ramp is activated is avoided, so that the method is more suitable for actual use, and flat road starting is smoother, more intelligent, more accurate and more comfortable.
本发明公开了一种用于自动挡商用车的坡道辅助功能自适应控制方法及系统,本发明的主要设计构思在于,通过读取当前车速信息、坡度信息、油门制动踏板信息、变速器挡位信息以及坡道辅助功能工况信息,自动识别是否激活或退出坡道辅助功能,在兼顾不同载荷重量情况之外,无需人为判断激活或解除,也无需手动操作(例如打开坡道辅助开关),车辆点火后即可正常起步驾驶,而坡道辅助功能会自适应激活及退出,并且规避了平路坡道辅助功能被激活的弊端,因而更为符合实际使用,使得平路起步更为平顺,同时更为智能、精准且舒适。
