The invention discloses a pedal demand torque control method and device, and belongs to the technical field of automobile transmissions. In order to solve the problem that the rotating speed of an engine fluctuates violently in the starting stage of a vehicle in a motion mode, under the method, a pedal torque three-dimensional diagram of a catalytic converter heating working condition is newly added, and the pedal required torque of a driver under the real-time requirement is obtained according to the three-dimensional diagram in the catalytic converter heating and heating ending stages; after a vehicle is started in a cold mode and enters a catalytic converter heating working condition, a specific accelerator pedal required torque is applied, so that the problems of poor driving feeling, emission deterioration and the like caused by slowing locking and releasing of a CVT gearbox due to excessive accelerator pedal torque requirements of driving modes such as movement and the like are solved.

    本申请公开了一种踏板需求扭矩控制方法及其装置,属于汽车变速器技术领域。为解决运动模式下的车辆起步阶段存在的发动机转速波动剧烈的问题,在该方法下,新增催化器加热工况的踏板扭矩三维图,并在催化器加热和加热结束阶段根据该三维图获取实时需求下的驾驶员踏板需求扭矩,使车辆冷机起动进入催化器加热工况后走特定的油门踏板需求扭矩,从而避免运动等驾驶模式过激的油门踏板扭矩需求导致CVT变速箱锁止、脱开变慢而引起的驾驶感受差、排放恶化等问题。
