The invention discloses an engine and gearbox coordination control method and device, equipment, a storage medium and a product, and relates to the technical field of vehicle control, the method comprises the steps that when it is detected that a target gear of a vehicle is inconsistent with a current gear, whether a transmission number ratio change exists in a gearbox of the vehicle or not is determined based on current working condition information of the vehicle; if not, the control priority of the vehicle is set to be coupling priority, and coupling control is conducted on an engine of the vehicle; if yes, the gear requirement of the vehicle is determined based on the real-time state information, and coordination control is conducted on an engine and a gearbox of the vehicle according to the gear requirement. The invention develops a coordination control strategy applied to engine coupling and gearbox gear shifting, and based on the strategy, the problem of transmission impact caused by mutual interference of gear shifting and coupling control in the prior art is avoided; therefore, on the premise that the driving experience of a user is guaranteed, coordinated control over engine coupling and gearbox gear shifting can be achieved.

    本申请公开了一种发动机与变速箱协调控制方法、装置、设备、存储介质及产品,涉及车辆控制技术领域,所述方法包括:当检测到车辆的目标挡位与当前挡位不一致时,基于车辆的当前工况信息确定车辆的变速箱是否存在传动数比变化;若不存在,则将车辆的控制优先级设定为耦合优先,并对车辆的发动机进行耦合控制;若存在,则基于实时状态信息确定车辆的挡位需求,并根据挡位需求对车辆的发动机与变速箱进行协调控制。本申请开发了一种应用于发动机耦合和变速箱换挡的协调控制策略,基于该策略避免了现有技术中由于换挡和耦合控制互相干涉而导致的传动冲击问题,进而能够在保证用户驾乘体验的前提下实现对发动机耦合和变速箱换挡的协调控制。
