The invention discloses a system and method for improving the starting smoothness of an electric motor coach. A first gravity sensor is arranged to collect the total mass of passengers getting on the coach, a second gravity sensor is arranged to collect the total mass of passengers getting off the coach, and therefore the current passenger carrying mass of the electric motor coach is obtained; and compensation torque which needs to be additionally supplemented and keeps the opening degree of an accelerator pedal consistent with the opening degree of the accelerator pedal at the idle-load ideal starting acceleration is calculated according to the passenger carrying mass, and therefore under the condition that the opening degree of the accelerator pedal is kept unchanged, a motor can accurately output the needed torque to achieve the ideal starting acceleration. The method can guarantee that the electric motor coach is started according to the preset acceleration under different loads, and the starting smoothness is improved.

    本发明提供一种提高电动客车起步平顺性的系统及方法,通过设置第一重力传感器采集上车乘客总质量,通过设置第二重力传感器采集下车乘客总质量,从而得到电动客车当前的载客质量,根据载客质量计算保持加速踏板开度与空载时理想起步加速度时加速踏板开度一致,需要额外补充的补偿扭矩,从而能在保持加速踏板开度不变的情况下,使电机准确输出所需要的扭矩以达到理想起步加速度,能够保证电动客车在不同载荷下按照所预设的加速度进行起步,提高起步平顺性。
