The invention provides a two-wheeled motorcycle traction force control system which comprises a wheel speed sensor, an anti-lock braking system, a traction force control system, an engine electronic injection electronic control system and an electronic injection driving system, the wheel speed sensor collects the rotation frequency of a front wheel and a rear wheel, and the wheel speed and the vehicle speed of the front wheel and the rear wheel are obtained through calculation; the slip ratio is calculated through the vehicle speed and the rear wheel speed, and the traction force control system outputs a target control torque signal according to the slip ratio and sends the target control torque signal to the engine electronic fuel injection electronic control system; the engine electronic injection electronic control system outputs a control instruction to the electronic injection driving system; the electronic fuel injection driving system outputs torque to the driving wheels to drive the motorcycle to move. The slip rate is calculated by collecting the rotation frequency of the front wheel and the rear wheel, whether the wheels slip or not is evaluated, and whether engine torque reduction is executed or not is controlled by intervening a traction force control system, so that a motorcycle body can be always kept stable and slip is restrained when the two-wheeled motorcycle starts or accelerates on a wet and slippery road surface with a large accelerator.

    本发明提供了一种两轮摩托车牵引力控制系统,包括轮速传感器、防抱死制动系统、牵引力控制系统、发动机电喷电控系统和电喷驱动系统,轮速传感器采集前轮和后轮转动的频率,计算得到前轮和后轮的轮速以及车速,通过车速和后轮轮速计算得到滑转率,牵引力控制系统根据滑转率的大小输出目标控制扭矩信号,并发送至发动机电喷电控系统;发动机电喷电控系统输出控制指令至电喷驱动系统;电喷驱动系统输出扭矩至驱动轮驱动摩托车运动。本发明通过采集前后轮的转动频率计算滑转率,来进行评估车轮是否打滑,再通过介入牵引力控制系统是否执行发动机降扭,从而使两轮摩托车在湿滑路面大油门起步或加速时车身能始终保持平稳,抑制打滑。
