The invention discloses an electric two-wheeled vehicle slip control method considering the slippery degree of a road surface, and relates to the technical field of vehicles, and the method comprises the following steps: when detecting that an electric two-wheeled vehicle slips, firstly, controlling a motor to work according to a preset negative torque in a first stage, and rapidly inhibiting slip; determining a road surface slip coefficient according to a driving state parameter of the electric two-wheeled vehicle when the electric two-wheeled vehicle slips, then controlling the motor to work according to a preset negative torque to reach a preset condition, increasing the torque according to the torque increment and controlling the motor to work from the initial given torque one by one in a control period in a second stage, and controlling the motor to work when the road surface slip coefficient is larger. The higher the represented road surface wet and slippery degree is, the smaller the determined torque increment is, so that the effects of slowly increasing the torque on the wet and slippery road surface to avoid slipping again and rapidly increasing the torque on the relatively non-wet and slippery road surface to avoid pause are achieved, the driving stability of the electric two-wheeled vehicle can be guaranteed, and the riding experience can be optimized.
本申请公开了一种考虑路面湿滑程度的电动两轮车打滑控制方法,涉及车辆技术领域,该方法在检测到电动两轮车发生打滑现象时,第一阶段首先按照预定负扭矩控制电机工作,快速抑制打滑,并根据电动两轮车在出现打滑现象时的行驶状态参数确定路面打滑系数,然后在按照预定负扭矩控制电机工作达到预定条件后,在第二阶段从初始给定扭矩开始逐控制周期按照扭矩增量增大扭矩并控制电机工作,路面打滑系数越大,表征的路面湿滑程度越高,确定的扭矩增量越小,从而达成在湿滑路面下缓慢增加扭矩避免再次打滑,在相对不湿滑路面下快速增加扭矩避免顿挫的效果,既可以保证电动两轮车行驶平稳性也可以优化乘坐体验。
