- Fig. 1 is a flow chart of a transmission gear control method according to an exemplary embodiment. As shown in Fig. 1, the method includes:
- Step 101 detecting whether the vehicle satisfies a preset pre-gear condition.
- the application scenario of the present disclosure can be the parking process of a hybrid vehicle in pure electric mode
- the subject of execution of the present disclosure can be the vehicle's VCU (English: Vehicle Control Unit, Chinese: vehicle controller), or It is the MCU of the vehicle (English: Motor Control Unit, Chinese: Motor Controller), and it can also be a dedicated controller installed on the vehicle, which is not specifically limited in this disclosure.
- VCU Vehicle Control Unit
- MCU Motor Control Unit
- the pure electric mode the hybrid vehicle is powered by the motor, and the engine does not provide power for the vehicle. At this time, the actual gear inside the gearbox is neutral (that is, N gear).
- the vehicle can be detected whether the vehicle meets the preset pre-gear condition. Specifically, when the vehicle speed is less than a preset first threshold (for example, 2 km/h), it can be determined that the user is about to stop the vehicle, and then it can be determined that the vehicle meets the pre-engagement condition. Or in the case of receiving a parking request, it can be determined that the vehicle is about to engage the parking gear, and then it can also be determined that the vehicle meets the pre-engagement condition. It should be noted that after the vehicle receives the parking request, it needs to execute a control step with a higher priority (such as controlling the torque reduction of the vehicle, etc.), and then put into the parking gear. Therefore, when a parking request is received, it can be determined that the vehicle meets the pre-engagement condition, and the pre-engagement is performed while the vehicle is executing a control step with a higher priority (that is, before the parking gear is engaged).
- a preset first threshold for example, 2 km/h
- Step 102 if the pre-engagement condition is met, control the shift fork of the gearbox of the vehicle to slide to the target position, and the target position is the edge of the position corresponding to the parking gear of the gearbox.
- the first control signal can be sent to the gearbox to control the shift fork of the gearbox to slide from the position corresponding to the neutral gear to the target position, wherein the target position can be understood as The position of the pre-engagement gear, that is, the edge of the position corresponding to the parking gear of the gearbox, the first control signal can be understood as a signal for controlling the shift fork to slide from the position corresponding to the neutral gear to the target position.
- a position sensor can be installed at the target position, and when the shift fork slides to the target position, it can be determined through the signal collected by the position sensor that the shift fork has reached the target position.
- the shift fork can have enough time to slide smoothly to the position corresponding to the park gear , Improve the stability of the vehicle in the parking gear.
- Step 103 detecting whether the vehicle satisfies a preset parking condition.
- Step 104 if the parking condition is met, control the shift fork to slide to the position corresponding to the parking gear.
- the shift fork After the shift fork reaches the target position, it can be detected whether the vehicle satisfies the preset parking condition. Specifically, when the vehicle receives a parking request and the control steps with a higher priority than engaging the parking gear (such as controlling the torque reduction of the vehicle, etc.) have been executed, it can be determined that the vehicle meets the parking condition. At this time, the second control signal may be sent to the gearbox to control the shift fork to slide smoothly from the target position to the position corresponding to the parking gear.
- the parking request can be understood as a request triggered by the driver by pressing a parking gear button on the vehicle body, and is used to instruct the vehicle to park.
- the second control signal can be understood as a signal for controlling the shift fork to slide from the target position to the position corresponding to the parking gear. Since the shift fork has already slid from the position corresponding to the neutral gear to the target position that is closer to the position corresponding to the parking gear, the shift fork can have enough time to slide smoothly to the position corresponding to the parking gear. The stability of the vehicle in the parking gear is improved.
- the present disclosure first detects whether the vehicle satisfies the preset pre-engagement condition, and if the pre-engagement condition is met, controls the shift fork of the vehicle's gearbox to slide to the target position, wherein the target position is the shifting position Position the edge of the box corresponding to the park gear. Afterwards, it is detected whether the vehicle meets the preset parking conditions, and if the parking conditions are met, the shift fork is controlled to slide to the position corresponding to the parking gear.
- the gear before the gearbox is engaged in the parking gear, the gear is pre-engaged to control the shift fork of the vehicle's gearbox to slide to the edge of the position corresponding to the parking gear in advance, so that the shift fork can slide smoothly To the corresponding position of the parking gear, the stability of the vehicle parking is improved.

- Step 1012 if the current vehicle speed is greater than the first threshold and less than or equal to the preset second threshold, and the historical vehicle speed is less than or equal to the first threshold, it is determined that the vehicle meets the pre-engagement condition.
- Step 1013 if the current vehicle speed is greater than the first threshold and less than or equal to the second threshold, and the historical vehicle speed is greater than the first threshold, it is determined that the vehicle does not meet the pre-engagement condition.
- Step 1014 if the current vehicle speed is greater than the second threshold, it is determined that the vehicle does not meet the pre-engagement condition, and the second threshold is greater than the first threshold.
- the vehicle may be determined whether the vehicle meets the pre-engagement condition by detecting the current vehicle speed of the vehicle. If the current vehicle speed of the vehicle is less than or equal to the preset first threshold, it can be determined that the vehicle meets the pre-engagement condition. If the current vehicle speed is greater than the first threshold, less than or equal to the preset second threshold, and the historical vehicle speed is less than or equal to the first threshold, then it is determined that the vehicle meets the pre-engagement condition, wherein the vehicle can be uninterrupted according to the preset collection period To collect the vehicle speed, correspondingly, the historical vehicle speed can be understood as the vehicle speed collected in the previous collection cycle at the current moment.
- the second threshold is greater than the first threshold
- the first threshold may be, for example, 2km/h
- the second threshold may be, for example, 3km/h.
- the first threshold is 2km/h
- the second threshold is 3km/h as an example for illustration. If the current vehicle speed is 1km/h, it can be determined that the vehicle meets the pre-engagement condition. If the current vehicle speed is 2.5km/h and the historical vehicle speed is 1.8km/h, it can be determined that the vehicle meets the pre-engagement condition. If the current vehicle speed is 2.5km/h and the historical vehicle speed is 3km/h, it can be determined that the vehicle does not meet the pre-engagement condition. If the current vehicle speed is 3.2km/h, it can be determined that the vehicle does not meet the pre-engagement condition.

- Step 1016 if a parking request is received, it is determined that the vehicle meets the pre-engagement condition.
- whether a pre-gear condition is met can be determined by judging whether a parking request is received.
- the parking request will be triggered. If the parking request is received, it means that the internal gear of the gearbox is about to be controlled from neutral to park gear, then It can be determined that the vehicle meets the pre-engagement condition, and the shift fork can be pre-controlled to slide from the position corresponding to the neutral gear to the target position before the VCU controls the transmission to engage the parking gear.

下面参考附图描述本公开实施例的变速箱挡位的控制方法、装置、车辆、程序和存储介质。
图1是根据一示例性实施例示出的一种变速箱挡位的控制方法的流程图，如图1所示，该方法包括：
步骤101，检测车辆是否满足预设的预挂挡条件。
举例来说，本公开的应用场景可以为混动车辆在纯电模式下的停车过程，本公开的执行主体可以是车辆的VCU(英文：Vehicle Control Unit，中文：整车控制器)，也可以是车辆的MCU(英文：Motor Control Unit，中文：电机控制器)，还可以是设置在车辆上的专用控制器，本公开对此不作具体限定。混动车辆在纯电模式下由电机来提供动力，发动机并不为车辆提供动力，此时变速箱内部的实际挡位为空挡(即N挡)。
首先，可以检测车辆是否满足预设的预挂挡条件。具体的，在车速小于预设的第一阈值(例如可以是2km/h)的情况下，可以判断用户即将停车，那么可以确定车辆满足预挂挡条件。或者在接收到驻车请求的情况下，可以确定车辆即将挂驻车挡，那么也可以确定车辆满足预挂挡条件。需要说明的是，当车辆接收到驻车请求之后，需要先执行优先级更高的控制步骤(如控制车辆的扭矩降低等)，然后再挂驻车挡。因此在接收到驻车请求的情况下，可以确定车辆满足预挂挡条件，并在车辆执行优先级更高的控制步骤 的同时(即在挂驻车挡之前)，进行预挂挡。
步骤102，若满足预挂挡条件，控制车辆的变速箱的换挡拨叉滑动至目标位置，目标位置为变速箱的驻车挡对应的位置的边缘。
示例的，在确定车辆满足预挂挡条件之后，可以将第一控制信号发送至变速箱，以控制变速箱的换挡拨叉从空挡对应的位置滑动至目标位置，其中，目标位置可以理解为预挂挡的位置，即变速箱的驻车挡对应的位置的边缘，第一控制信号可以理解为，用于控制换挡拨叉从空挡对应的位置滑动至目标位置的信号。具体的，可以在目标位置处安装位置传感器，当换挡拨叉滑动至目标位置时，可以通过位置传感器采集到的信号确定换挡拨叉已到达目标位置。这样，通过预先控制换挡拨叉从空挡对应的位置，滑动至距离驻车挡对应的位置较近的目标位置，使得换挡拨叉可以有充足的时间平缓地滑动至驻车挡对应的位置，提高了车辆挂驻车挡的平稳性。
步骤103，检测车辆是否满足预设的驻车条件。
步骤104，若满足驻车条件，控制换挡拨叉滑动至驻车挡对应的位置。
进一步的，当换挡拨叉到达目标位置之后，可以检测车辆是否满足预设的驻车条件。具体的，当车辆接收到驻车请求，且比挂驻车挡优先级更高的控制步骤(如控制车辆的扭矩降低等)已经执行完成时，可以确定车辆满足驻车条件。这时，可以将第二控制信号发送至变速箱，以控制换挡拨叉平滑地从目标位置滑动至驻车挡对应的位置。其中，驻车请求可以理解为，驾驶员通过按压车身上的驻车挡按钮触发的请求，用于指示车辆驻车。第二控制信号可以理解为，用于控制换挡拨叉从目标位置滑动至驻车挡对应的位置的信号。由于换挡拨叉已经通过预先从空挡对应的位置，滑动至距离驻车挡对应的位置较近的目标位置，因此换挡拨叉可以有充足的时间平缓地滑动至驻车挡对应的位置，提高了车辆挂驻车挡的平稳性。
综上所述，本公开首先检测车辆是否满足预设的预挂挡条件，在满足预挂挡条件的情况下，控制车辆的变速箱的换挡拨叉滑动至目标位置，其中目标位置为变速箱的驻车挡对应的位置的边缘。之后检测车辆是否满足预设的驻车条件，在满足驻车条件的情况下，控制换挡拨叉滑动至驻车挡对应的位置。本公开通过在变速箱挂驻车挡之前，先进行预挂挡，以控制车辆的变速箱的换挡拨叉预先滑动至驻车挡对应的位置的边缘，使得换挡拨叉可以平稳地滑动至驻车挡对应的位置，提高了车辆驻车的平稳性。
图2是根据一示例性实施例示出的另一种变速箱挡位的控制方法的流程图，如图2 所示，步骤101可以通过以下步骤来实现：
步骤1011，若车辆的当前车速小于或等于预设的第一阈值，则确定车辆满足预挂挡条件。
步骤1012，若当前车速大于第一阈值且小于或等于预设的第二阈值，以及历史车速小于或等于第一阈值，则确定车辆满足预挂挡条件。
步骤1013，若当前车速大于第一阈值且小于或等于第二阈值，以及历史车速大于第一阈值，则确定车辆不满足预挂挡条件。
步骤1014，若当前车速大于第二阈值，则确定车辆不满足预挂挡条件，第二阈值大于第一阈值。
示例的，可以通过检测车辆的当前车速来确定车辆是否满足预挂挡条件。如果车辆的当前车速小于或等于预设的第一阈值，那么可以确定车辆满足预挂挡条件。如果当前车速大于第一阈值，小于或等于预设的第二阈值，且历史车速小于或等于第一阈值，那么确定车辆满足预挂挡条件，其中，车辆可以按照预设的采集周期不间断地采集车速，相应的，历史车速可以理解为，当前时刻的上一个采集周期采集的车速。如果当前车速大于第一阈值，小于或等于第二阈值，且历史车速大于第一阈值，那么可以确定车辆不满足预挂挡条件。如果当前车速大于第二阈值，那么可以确定车辆不满足预挂挡条件。其中，第二阈值大于第一阈值，第一阈值例如可以是2km/h，第二阈值例如可以是3km/h。这样，在车速低于第一阈值时，可以判断驾驶员即将停车，因此可以确定车辆满足预挂挡条件，并且可以确保车辆在停车过程中，当车速已经小于或等于第一阈值，在由于道路颠簸等因素导致车速在短时间内突然大于第一阈值，且小于或等于第二阈值的情况下，仍然可以判断车辆满足预挂挡条件，避免了车辆多次进行预挂挡，提高了预挂挡过程的稳定性。
具体的，以第一阈值为2km/h，第二阈值为3km/h为例来举例说明。若当前车速为1km/h，那么可以确定车辆满足预挂挡条件。若当前车速为2.5km/h，且历史车速为1.8km/h，那么可以确定车辆满足预挂挡条件。若当前车速为2.5km/h，且历史车速为3km/h，那么可以确定车辆不满足预挂挡条件。若当前车速为3.2km/h，那么可以确定车辆不满足预挂挡条件。
图3是根据一示例性实施例示出的另一种变速箱挡位的控制方法的流程图，如图3所示，步骤101还可以通过以下步骤来实现：
步骤1015，检测是否接收到驻车请求，驻车请求用于指示车辆驻车。
步骤1016，若接收到驻车请求，确定车辆满足预挂挡条件。
示例的，在另一种应用场景中，可以通过判断是否接收到驻车请求，来确定是否满足预挂挡条件。当驾驶员通过车身按键将车辆的挡位设置为驻车挡时，会触发驻车请求，如果接收到驻车请求，表示变速箱的内部挡位即将被控制从空挡变为驻车挡，那么可以确定车辆满足预挂挡条件，可以在VCU控制变速箱挂驻车挡之前，预先控制换挡拨叉从空挡对应的位置滑动至目标位置。由于目标位置为变速箱的驻车挡对应的位置的边缘，距离驻车挡较近，因此，当车辆满足驻车条件时，换挡拨叉可以有充足的时间平缓地从目标位置，滑动至驻车挡对应的位置，提高了车辆挂驻车挡的平稳性。其中，驻车请求用于指示车辆驻车。
在一种应用场景中，变速箱包括平行的第一滑轨和第二滑轨，第一滑轨包括行车挡，第二滑轨包括驻车挡。
步骤102的一种实现方式可以为：
控制换挡拨叉滑动至第一滑轨上的行车挡位置，以使换挡拨叉滑动至第二滑轨上的目标位置。
示例的，一种变速箱的内部结构如图4所示，变速箱可以包括第一滑轨和第二滑轨，且第一滑轨和第二滑轨平行，换挡拨叉可以同时在第一滑轨和第二滑轨上，沿平行于第一滑轨和第二滑轨的方向移动。其中，第一滑轨可以包括行车挡，第二滑轨可以包括驻车挡，行车挡可以包括空挡、1挡、2挡等。需要说明的是，1挡在第一滑轨上对应的位置投影至第二滑轨的区域，能够覆盖驻车挡在第二滑轨上对应的位置。因此，当换挡拨叉对应的电机推动换挡拨叉在第一滑轨和第二滑轨上，沿平行于第一滑轨和第二滑轨的方向移动时，如果检测到换挡拨叉在第一滑轨上处于1挡对应的位置，那么可以确定换挡拨叉在第二滑轨上处于目标位置。因此，在预挂挡时，可以通过检测变速箱是否挂1挡来确定换挡拨叉是否滑动至目标位置，也就是说，当检测到变速箱挂1挡时，可以确定换挡拨叉已滑动至目标位置。
在一种应用场景中，驻车条件包括：
接收到驻车请求。
车辆的当前车速小于或等于预设的第三阈值。
车辆的禁止驻车功能为关闭状态。
示例的，在检测车辆是否满足预设的驻车条件时，可以检测是否接收到驻车请求，判断车辆的当前车速是否小于或等于预设的第三阈值，并且检测车辆的禁止驻车功能是否为关闭状态。具体的，驻车请求可以理解为向车辆的变速箱发送的请求，该请求中包括驻车挡位，用于控制变速箱调整为驻车挡位。第三阈值与第二阈值可以相同也可以不同，第三阈值例如可以是2km/h。如果接收到驻车请求，车辆的当前车速小于或等于第三阈值，且车辆的禁止驻车功能为关闭状态，那么可以确定车辆满足驻车条件，可以执行挂驻车挡的操作。
综上所述，本公开首先检测车辆是否满足预设的预挂挡条件，在满足预挂挡条件的情况下，控制车辆的变速箱的换挡拨叉滑动至目标位置，其中目标位置为变速箱的驻车挡对应的位置的边缘。之后检测车辆是否满足预设的驻车条件，在满足驻车条件的情况下，控制换挡拨叉滑动至驻车挡对应的位置。本公开通过在变速箱挂驻车挡之前，先进行预挂挡，以控制车辆的变速箱的换挡拨叉预先滑动至驻车挡对应的位置的边缘，使得换挡拨叉可以平稳地滑动至驻车挡对应的位置，提高了车辆驻车的平稳性。
为了实现上述实施例，本公开还提出了一种变速箱挡位的控制装置。

若当前车速大于第一阈值且小于或等于预设的第二阈值，以及历史车速小于或等于第一阈值，则确定车辆满足预挂挡条件；
若当前车速大于第一阈值且小于或等于第二阈值，以及历史车速大于第一阈值，则确定车辆不满足预挂挡条件；
