The invention discloses a reverse gear control method and device for a hybrid electric vehicle. The method comprises the steps: obtaining the gear shifting information of a gear shifting operation after the gear shifting operation of a driver on a gear shifting rod is detected; obtaining a driving mode of the automobile; according to the gear shifting information and the driving mode of the automobile, setting a motor gear of the automobile, and setting an engine gear and a reverse gear position of the automobile; analyzing an accelerator signal to obtain an initial reverse gear torque of theautomobile; and distributing the initial reverse gear torque to the engine and the motor to serve as target reverse gear torque so that the engine and the motor can output the corresponding target reverse gear torque according to the set gears. Visibly, according to the automobile driving mode and the gear shifting operation of a driver, the proper positions of the motor, the engine gear and the reverse gear are arranged, so that the motor and the engine gear output respective corresponding reverse gear torques conveniently, the reverse gear is engaged and disengaged in due time while the reverse gear dynamic property is met, the gear engaging efficiency and the gear shifting smoothness are improved, and the driving experience is improved.

    本申请公开了一种混合动力汽车的倒挡控制方法及装置,当检测到驾驶员对换挡杆的换挡操作后,获取该换挡操作的换挡信息;获取汽车的驱动模式;根据换挡信息以及汽车的驱动模式,设置汽车的电机挡位,以及设置汽车的发动机挡位和倒挡齿轮位置;对油门信号进行解析,得到汽车的初始倒挡扭矩;将初始倒挡扭矩分配给发动机及电机作为目标倒挡扭矩,以便发动机及电机根据设置的挡位,输出各自对应的目标倒挡扭矩。可见,本申请根据汽车驱动模式以及驾驶员的换挡操作,设置适当的电机以及发动机挡位和倒挡齿轮位置,便于二者输出各自对应的倒挡扭矩,实现了在满足倒挡动力性的同时,适时挂入和脱开倒挡齿轮,提高挂挡效率以及换挡平顺性,提升驾驶体验。
