The invention relates to a method for controlling driving of an electric vehicle to achieve expected performance of the electric vehicle, in particular to improvement of an existing driving request torque map, and provides a driving request torque determining method and device based on the utilization rate. The driving request torque calculation method based on the utilization rate comprises the steps that the utilization rate Map is established, and the utilization rate Map is the proportional relation between a first driving request torque and a first maximum torque in different vehicle states; when the first maximum torque is switched to the second maximum torque, the first driving request torque is updated to the second driving request torque according to the operation rate Map table lookup; according to the calculation method, tedious calibration can be avoided, and the driving request torque can be updated according to the new maximum torque only by looking up the table and using the utilization rate Map. Thus, no matter how the first maximum torque changes, the driving request torque can be quickly and accurately adjusted, and the development efficiency of the vehicle model and the convenience of iterative updating are improved.

    本发明涉及用于控制电动车辆驱动以达到其预想性能的方法,尤其涉及对现有的驾驶请求扭矩map进行改良,所提供一种基于稼动率的驾驶请求扭矩确定方法及装置;用于基于稼动率的驾驶请求扭矩计算方法,包括:建立稼动率Map,其中稼动率Map为在不同车辆状态下第一驾驶请求扭矩和第一最大扭矩的比例关系;在第一最大扭矩切换到第二最大扭矩时,根据在稼动率Map查表来更新第一驾驶请求扭矩至第二驾驶请求扭矩;该计算方法可以避免重新进行繁琐的标定,只需通过查表使用稼动率Map即可根据新的最大扭矩来更新驾驶请求扭矩。这样,无论第一最大扭矩如何变化,都可以快速而准确地调整驾驶请求扭矩,提高车型的开发效率和迭代更新的便利性。
