The invention relates to a vehicle working mode switching control method and device and a vehicle. The vehicle working mode switching control device comprises a first switch module, a bus capacitor, abridge arm converter, a motor winding, a second switch module, an energy storage element and a controller. If one of a current working mode and a target working mode is an oscillation heating mode, the controller determines a target switching preprocessing strategy from a plurality of switching preprocessing strategies based on the current working mode and the target working mode, a bridge arm converter is controlled so that a first switch module and a second switch module are used for executing the target switching preprocessing strategy and switching from the current working mode to the target working mode, and the multiple switching preprocessing strategies comprise a preprocessing strategy for switching the oscillation heating mode and other working modes. By adopting the technical scheme, the switching processing rate and the mode switching safety are improved.

    本申请涉及一种车辆工作模式切换控制方法、装置和车辆,该车辆工作模式切换控制装置,其包括第一开关模块,母线电容,桥臂变换器,电机绕组,第二开关模块;储能元件以及控制器,该控制器用于若当前工作模式和目标工作模式两者中一者为振荡加热模式,则基于当前工作模式和目标工作模式从多个切换预处理策略中确认目标切换预处理策略,并通过控制所述桥臂变换器,所述第一开关模块和所述第二开关模块,以执行所述目标切换预处理策略,从所述当前工作模式切换至所述目标工作模式,其中,所述多个切换预处理策略包括所述振荡加热模式与其他工作模式进行切换的预处理策略。通过采用上述技术方案,提升了切换处理速率和模式切换安全性。
