The invention discloses a method for calculating the output torque of an intelligent networked electric vehicle, belongs to the technical field of electric vehicle driving control, and solves the problem that in the prior art, the output torque calculation of a rear vehicle is unreasonable, and the driving safety of the rear vehicle is poor under the vehicle following condition. The method for calculating the output torque of an intelligent networked electric vehicle comprises the following steps: obtaining an early warning level of a rear vehicle according to a safety distance, the speed of afront vehicle, the speed of the rear vehicle, a vehicle head time interval and a real-time distance between the front vehicle and the rear vehicle; determining whether the rear vehicle performs pedaldriving in a soft pedal mode, a linear pedal mode or a hard pedal mode according to the early warning level, and determining the required torque of the rear vehicle according to the determined pedalmode, accelerator pedal change and accelerator pedal change rate; and determining the output torque of the rear vehicle according to the pedal mode of the rear vehicle and the required torque of the rear vehicle. The output torque of the rear vehicle under the vehicle following condition is calculated more reasonably, and the driving safety of the rear vehicle under the vehicle following conditionis enhanced.
本发明公开一种智能网联电动汽车输出转矩计算方法,属于电动汽车驱动控制技术领域,解决了现有技术中后车的输出转矩计算不合理、跟车情况下后车驾驶安全性较差的问题。一种智能网联电动汽车输出转矩计算方法,根据所述安全距离、前车车速、后车车速、车头时距及前后两车实时距离获取后车的预警级别;根据所述预警级别,确定后车是进行软性踏板模式、线性踏板模式还是硬性踏板模式的踏板驱动,根据确定的踏板模式、加速踏板变化及加速踏板变化率,确定后车的需求转矩;根据所述后车的踏板模式及后车的需求转矩确定后车的输出转矩。更合理的计算出了跟车情况下后车的输出转矩,增强了跟车情况下后车驾驶安全。
