具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请实施例的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。
本申请实施例中采用诸如“第一”、“第二”的前缀词，仅仅为了区分不同的描述对象，对被描述对象的位置、顺序、优先级、数量或内容等没有限定作用。本申请实施例中对序数词等用于区分描述对象的前缀词的使用不对所描述对象构成限制，对所描述对象的陈述参见权利要求或实施例中上下文的描述，不应因为使用这种前缀词而构成多余的限制。此外，在本实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
图1是本申请实施例提供的运载工具100的一个功能框图示意。运载工具100可以包括感知系统120、发声装置130和计算平台150，其中，感知系统120可以包括感测关于运载工具100周边的环境的信息的一种或多种传感器。例如，感知系统120可以包括定位系统，定位系统可以是全球定位系统(global positioning system，GPS)，也可以是北斗系统或者其他定位系统。感知系统120还可以包括惯性测量单元(inertial measurement unit， IMU)、激光雷达、毫米波雷达、超声雷达以及摄像装置中的一种或者多种。
运载工具100的部分或所有功能可以由计算平台150控制。计算平台150可包括一个或多个处理器，例如处理器151至15n(n为正整数)，处理器是一种具有信号的处理能力的电路，在一种实现中，处理器可以是具有指令读取与运行能力的电路，例如中央处理单元(central processing unit，CPU)、微处理器、图形处理器(graphics processing unit，GPU)(可以理解为一种微处理器)、或数字信号处理器(digital signal processor，DSP)等；在另一种实现中，处理器可以通过硬件电路的逻辑关系实现一定功能，该硬件电路的逻辑关系是固定的或可以重构的，例如处理器为专用集成电路(application-specific integrated circuit，ASIC)或可编程逻辑器件(programmable logic device，PLD)实现的硬件电路，例如现场可编程门阵列(field programmable gate array，FPGA)。在可重构的硬件电路中，处理器加载配置文档，实现硬件电路配置的过程，可以理解为处理器加载指令，以实现以上部分或全部单元的功能的过程。此外，处理器还可以是针对人工智能设计的硬件电路，其可以理解为一种ASIC，例如神经网络处理单元(neural network processing unit，NPU)、张量处理单元(tensor processing unit，TPU)、深度学习处理单元(deep learning processing unit，DPU)等。此外，计算平台150还可以包括存储器，存储器用于存储指令，处理器151至15n中的部分或全部处理器可以调用存储器中的指令，执行指令，以实现相应的功能。
如前所述，随着车辆的智能化，用户在驾驶车辆行驶的过程中，车辆可以主动对周围的目标进行预警。例如，对于前方穿插的行人或者车辆，可以通过车载显示屏显示图像或者文字进行预警。又例如，对于盲区预警目标，可以通过后视镜上的指示灯进行预警。但是这些预警方式需要用户的注意力转移至车载显示屏或者后视镜上，不利于用户的驾乘安全。
本申请实施例提供了一种控制方法、装置和运载工具，通过控制运载工具中的至少两个发声装置发出声像漂移方向与该运载工具和目标的相对运动趋势相对应的提示音。这样，用户可以在注意力不受影响的情况下，通过该提示音的声像漂移方向获知该运动趋势，有助于提升用户的驾乘安全；同时，也有助于提升运载工具的智能化程度。
以运载工具100是车辆为例，图2是本申请实施例提供的车辆200的示意性结构图。如图2所示，该车辆200包括计算平台210、位于座舱外的摄像头221-222、雷达231-238以及位于座舱内的扬声器241-249。计算平台210可以通过座舱外的摄像头221-222以及雷达231-238采集的数据，可以确定目标是否进入车辆200的告警范围内。在目标进入车辆200的告警范围内时，计算平台210可以控制扬声器241-249中的至少两个扬声器发出提示音，该提示音的声像漂移方向与该目标和车辆200的相对运动趋势相对应，或者，该提示音的声像漂移方向与该目标本身的运动趋势相对应。
以上该目标和该车辆200的相对运动趋势可以为目标相对于车辆200的运动趋势，或者，也可以为车辆200相对于目标的运动趋势。
以上该目标本身的运动趋势可以为该目标不相对于任何参考物体的运动趋势。
以上图2中的座椅1可以为主驾区域的座椅，座椅2可以为副驾区域的座椅，座椅3可以为二排右侧区域的座椅，座椅4可以为二排左侧区域的座椅。
以上计算平台210可以为图1中的计算平台150，摄像头221-222以及雷达231-238可以位于图1中的感知系统120中，扬声器241-249可以位于图1中的发声装置130中。
以上图2中是以车辆200中包括2个摄像头、8个雷达以及9个扬声器为例进行说明的，本申请实施例中对车辆200中摄像头、雷达以及扬声器的数量并不作具体限定。
以扬声器241为例，扬声器241的位置可以包括一个或者多个扬声器。例如，当该扬声器241的位置上包括多个扬声器时，该多个扬声器可以组成扬声器群。
图3示出了本申请实施例提供的一种应用场景的示意图。该应用场景为前方侧向穿插碰撞预警(front crossing traffic alert)场景。车辆1可以通过摄像头和雷达采集车辆2的信息，例如，车辆2的信息包括车辆2与车辆1之间的距离、车辆2的速度、车辆2的速度方向、车辆2的航向角等信息。在检测到车辆2进入车辆1的告警范围时，车辆1可以控制车辆1中至少两个扬声器发出提示音，该提示音的声像漂移方向与车辆2和车辆1的相对运动趋势相对应，或者，该提示音的声像漂移方向与车辆2本身的运动趋势相对应。
以上车辆2和车辆1的相对运动趋势可以为车辆2相对于车辆1的运动趋势，或者，也可以为车辆1相对于车辆2的运动趋势。以下实施例中以车辆2相对于车辆1的运动趋势为例进行说明。
例如，如图3所示，车辆2相对于车辆1的运动趋势为由东向西行驶，此时车辆1可以控制扬声器241-243发出提示音，该提示音的声像漂移方向为由东向西，或者，该提示音的声像漂移方向由副驾区域指向主驾区域，或者，该提示音的声像漂移方向为由扬声器241指向扬声器243。
又例如，车辆1也可以控制扬声器244-246发出提示音，该提示音的声像漂移方向为由东向西。
又例如，车辆1也可以控制扬声器247-249发出提示音，该提示音的声像漂移方向为由东向西。
这样，驾驶员通过提示音的声像漂移方向可以准确获知车辆2相对于车辆1的运动趋势，从而可以根据车辆2相对于车辆1的运动趋势对车辆1进行操控，有助于提升用户的驾乘安全；同时，也有助于提升车辆的智能化程度。
同时，在车辆1内部多个提示音迸发时，通过声像漂移的提示音可以使得用户准确获知多个提示音中对车辆2和车辆1的相对运动趋势进行提示的提示音。例如，在车辆1变道场景下，声像漂移方向与车辆2和车辆1的相对运动趋势相对应的提示音、前方雷达预警提示音、转向灯声音可能会迸发。驾驶员可以准确理解声像漂移方向与该相对运动趋势相对应的提示音对应的功能语义，从而避免了驾驶员对车辆的声学提示音产生消极评价和混乱理解，有助于提升用户的驾乘体验。
一个实施例中，车辆1可以控制车辆1中至少两个扬声器发出提示音，包括：车辆1控制该至少两个扬声器发出声音的播放强度。
以控制扬声器241-243为例，车辆1可以控制扬声器241-243发出的声音之间没有时延且控制扬声器241-243发出的声音的播放强度不同。例如，在T 1时刻，可以控制扬声器241发出的声音的播放强度为40dB，控制扬声器242发出的声音的播放强度为20dB且控制扬声器243发出的声音的播放强度为20dB；在T 1时刻之后的T 2时刻，可以控制扬声器241发出的声音的播放强度为20dB，控制扬声器242发出的声音的播放强度为40dB且控制扬声器243发出的声音的播放强度为20dB；在T 2时刻之后的T 3时刻，可以控制扬声器241发出的声音的播放强度为20dB，控制扬声器242发出的声音的播放强度为20dB且控制扬声器243发出的声音的播放强度为40dB。从而可以控制扬声器241-243发出声像漂 移方向为由东向西的提示音，或者，发出声像漂移方向为由扬声器241指向扬声器243的提示音。
一个实施例中，该扬声器241、扬声器242或者扬声器244的位置上可以包括一个或者多个扬声器。以扬声器241的位置上包括多个扬声器为例，控制扬声器241发出的声音的播放强度为40dB，包括：控制该多个扬声器中的至少部分扬声器发出的声音的播放强度为40dB。
一个实施例中，T 1时刻和T 2时刻之间的时间间隔，T 2时刻和T 3时刻之间的时间间隔可以是相等的，或者，也可以是不相等的。例如，若T 1时刻和T 2时刻之间的时间间隔，T 2时刻和T 3时刻之间的时间间隔相等时，该时间间隔可以为10毫秒(millisecond，ms)。
一个实施例中，车辆1可以对该提示音进行预设时长的播报。
示例性的，该预设时长内包括多个播报周期，每个播报周期内可以均可以控制扬声器241-243发出声像漂移方向为由东向西的提示音。
一个实施例中，在该预设时长结束之前检测到车辆2驶出该车辆1的告警范围内，还可以继续控制扬声器241-243发出提示音，直到该预设时长结束。或者，在完成车辆2驶出车辆1的告警范围的时刻所在的播报周期内提示音的播报后，可以停止该提示音的播报。
一个实施例中，该T 1时刻可以为检测到车辆2进入车辆1的告警范围内的时刻。
一个实施例中，车辆1可以控制车辆1中至少两个扬声器发出提示音，包括：车辆1控制该至少两个扬声器发出声音的时延。
以控制扬声器241-243为例，车辆1可以控制扬声器241-243发出的声音的播放强度相同且扬声器241-243发出的声音的时延不同。例如，在T 1时刻，可以控制扬声器241发出的声音的播放强度为20dB且控制扬声器242和扬声器243不发出声音；在T 1+△T时刻，控制扬声器242发出的声音的播放强度为20dB且控制扬声器241和扬声器243不发出声音；在T 1+2△T时刻，控制扬声器243发出的声音的播放强度为20dB且控制扬声器241和扬声器242不发出声音。从而可以控制扬声器241-243发出声像漂移方向为由东向西的提示音，或者，发出声像漂移方向为由扬声器241指向扬声器243的提示音。
一个实施例中，车辆1可以控制车辆1中至少两个扬声器发出提示音，包括：车辆1控制该至少两个扬声器发出声音的时延和播放强度。
以控制扬声器241-243为例，车辆1可以控制扬声器241-243发出的声音的时延不同且控制扬声器241-243发出的声音的播放强度不同。例如，在T 1时刻，可以控制扬声器241发出的声音的播放强度为40dB且控制扬声器242和扬声器243不发出声音；在T 1+△T时刻，控制扬声器242发出的声音的播放强度为20dB且控制扬声器241和扬声器243不发出声音；在T 1+2△T时刻，控制扬声器243发出的声音的播放强度为20dB且控制扬声器241和扬声器242不发出声音。
在T 2时刻，可以控制扬声器241发出的声音的播放强度为20dB且控制扬声器242和扬声器243不发出声音；在T 2+△T时刻，控制扬声器242发出的声音的播放强度为40dB且控制扬声器241和扬声器243不发出声音；在T 2+2△T时刻，控制扬声器243发出的声音的播放强度为20dB且控制扬声器241和扬声器242不发出声音。

图4示出了本申请实施例提供的车辆1的告警范围的示意图。如图4所示，可以通过车辆1与目标之间的距离确定车辆1的告警范围，例如，该告警范围可以为以车辆1上的某个点为圆心的圆形区域，该圆形区域的半径可以为预设距离L(例如，20米(meter，m))。在检测到车辆2进入该圆形区域时，可以确定车辆2进入车辆1的告警范围。
以上图4中是以车辆1与目标之间的距离来确定目标是否进入车辆1的告警范围，本申请实施例对于告警范围的确定并不限于此。例如，还可以通过目标与车辆1的TTC来确定目标是否进入车辆1的告警范围。例如，在检测到车辆1与目标之间的TTC小于或者等于预设时长(例如，5秒(second，s))时，可以确定目标进入车辆1的告警范围；或者，在检测到车辆1与目标之间的TTC大于该预设时长时，可以确定目标未进入车辆1的告警范围。
一个实施例中，车辆1还可以根据从云端服务器获取的数据确定车辆1的告警范围。
一个实施例中，车辆1可以通过车辆2相对于车辆1的方位确定该至少两个扬声器中的起始扬声器。
例如，图5示出了本申请实施例提供的扬声器与目标所在方位(或者区域)的对应关系的示意图。可以看出，车辆2首先进入该告警范围中的区域1，此时可以根据该对应关系确定起始扬声器为扬声器241。
以上起始扬声器也可以理解为声像漂移方向上始端的扬声器。
一个实施例中，车辆1可以根据被提示用户所在的位置确定该至少两个扬声器中的终止扬声器。
例如，以图3所示的应用场景为例，在车辆2进入车辆1的告警范围内时，可以确定此时需要对驾驶员进行提示，从而可以选择距离驾驶员所在位置最近的扬声器243为终止扬声器。从而在车辆2相对于车辆1的运动趋势为由东向西运动时，控制扬声器241-243发出声像漂移方向为由东至西的提示音。
又例如，图6示出了本申请实施例提供的另一应用场景的示意图。如图6中的(a)所示，当车辆2相对于车辆1的运动趋势从由东向西调整为由南向北行驶时，可以切换至控制扬声器249、扬声器246和扬声器243发出声像漂移的提示音，该提示音的声像漂移方向为由南向北，或者，该提示音的声像漂移方向为由扬声器249指向扬声器243。
又例如，如图6中的(b)所示，当车辆2相对于车辆1的运动趋势从由东向西调整为由南向北行驶时，可以切换至控制扬声器247、扬声器248、扬声器249、扬声器246和扬声器243发出声像漂移的提示音，该提示音的声像漂移方向与该车辆2在该告警范围内相对于车辆1的运动趋势相对应，或者，该提示音的声像漂移方向为先由东向西，再由南向北。
通过被提示用户所在的位置确定该至少两个扬声器中的终止扬声器的位置，这样可以提升驾驶员对于目标和车辆1的相对运动趋势的感知能力，有助于驾驶员根据目标和车辆1的相对运动趋势快速做出驾驶决策，从而有助于提升用户的驾乘安全。
以上终止扬声器也可以理解为声像漂移方向末端的扬声器。
以上终止扬声器也可以与被提示用户所在的位置不相关。例如，当车辆2相对于车辆1的运动趋势从由东向西调整为由南向北行驶时，可以切换至控制扬声器248、扬声器245和扬声器242发出声像漂移的提示音，该提示音的声像漂移方向为由南向北，或者，该提示音的声像漂移方向为由扬声器248指向扬声器242。
一个实施例中，车辆1可以根据传感器采集的数据预测未来一段时间内目标相对于车辆1的运动趋势。
一个实施例中，车辆1可以根据目标进入车辆1的告警范围时的状态，预测未来一段时间内目标相对于车辆1的运动趋势。
示例性的，目标进入车辆1的告警范围时的状态包括但不限于目标进入车辆1的告警范围内时的速度、加速度、速度方向、航向角方向或者航向角速度率中的一个或者多个。
以图3所示的应用场景为例，当预测得到的车辆2相对于车辆1的运动趋势为由东向西时，车辆1可以根据该预测得到的运动趋势，确定车辆2在未来一段时间内会依次经过告警范围中的区域1、区域2和区域3。由于区域1和扬声器241具有对应关系，区域2和扬声器242具有对应关系且区域3和扬声器243具有对应关系，车辆1可以控制扬声器241-243发出提示音，该提示音的声像漂移方向与该运动趋势相对应。这样，在车辆2进入区域1且未进入区域2时，车辆1就可以控制扬声器241-243发出声像能漂移的提示音。通过扬声器241-243发出的声像漂移的提示音，使得用户提前获知车辆2相对于车辆1的运动趋势，帮助用户根据该运动趋势提前做出驾驶决策，有助于提升用户的驾乘安全。
一个实施例中，在预测得到的车辆2相对于车辆1的运动趋势与车辆2相对于车辆1的实际运动趋势不同时，控制该多个扬声器中的至少两个扬声器发出声像漂移方向与该实际运动趋势相对应的提示音。
例如，在车辆2进入车辆1的告警范围内时，车辆1可以根据预测得到的车辆2相对于车辆1的运动趋势，控制至少两个扬声器发出第一声像漂移方向的提示音，该第一声像漂移方向与预测得到的车辆2相对于车辆1的运动趋势相对应。在预测得到的车辆2相对于车辆1的运动趋势与车辆2相对于车辆1的实际运动趋势不一致时，车辆1可以切换至控制至少两个扬声器发出第二声像漂移方向的提示音，该第二声像漂移方向与该实际运动趋势相对应。
一个实施例中，当车辆2位于区域1且还未进入区域2时，车辆1可以控制扬声器241发出提示音，扬声器241发出的提示音用于提示目标已经进入了车辆1的告警范围且目标位于与扬声器241相对应的方位(或者，与扬声器241相对应的区域1)。当车辆2从区域1驶入区域2时，车辆1可以控制扬声器241和242发出提示音，该提示音的声像漂移方向与车辆2相对于车辆1的运动趋势相对应，例如，该提示音的声像漂移方向为由东向西，或者，该提示音的声像漂移方向为由扬声器241指向扬声器242。当车辆2从区域2驶入区域3时，车辆1可以控制扬声器241-243发出提示音，该提示音的声像漂移方向与车辆2相对于车辆1的运动趋势相对应，例如，该提示音的声像漂移方向为由东向西，该提示音的声像漂移方向为由扬声器241指向扬声器243。
一个实施例中，车辆1可以根据座舱外的传感器采集的数据确定车辆2相对于车辆1的运动趋势，从而根据该运动趋势控制该至少两个发声装置发出提示音，该提示音的声像漂移方向与该运动趋势相对应。
例如，如图5所示，当车辆2位于区域1且还未进入区域2时，车辆1可以根据车辆 1的座舱外的传感器(例如，摄像头、激光雷达以及毫米波雷达中的一种或者多种)确定车辆2相对于车辆1的运动趋势，从而控制至少两个发声装置发出声像漂移的提示音。例如，车辆2在区域1中相对于车辆1的运动趋势为由东向西行驶，那么车辆1可以控制扬声器241-243发出提示音，该提示音的声像漂移方向为由东向西。
一个实施例中，车辆1也可以根据云端服务器发送的数据确定车辆2相对于车辆1的运动趋势。
一个实施例中，车辆1可以控制提示音的声像漂移速度。
一个实施例中，车辆1可以控制提示音的声像漂移速度，包括：车辆1根据车辆1和目标之间的信息，控制提示音的声像漂移速度。例如，车辆1和目标之间的信息包括但不限于目标相对于车辆1的运动趋势、告警等级、车辆1和目标之间的距离以及车辆1和目标之间的TTC中的一个或者多个。
例如，该目标相对于车辆1的运动趋势中包括目标相对于车辆1的加速度。以图3所示的应用场景为例，当车辆2进入车辆1的告警范围后，若车辆2相对于车辆1的加速度越来越大，则可以控制扬声器241-243发出的提示音的声像漂移速度越来越快。表1示出了一种目标相对于车辆1的加速度与声像漂移速度之间的对应关系。

以上结合图3至图8介绍了前方侧向穿插碰撞预警场景下，车辆1控制至少两个扬声器发出声像漂移的提示音的过程。下面结合图9至图10介绍本申请实施例提供的其他应用场景。例如，本申请实施例还可以应用于驾驶盲区监测预警(blind spod detection)场景。驾驶盲区监测预警场景包括但不限于盲区监测预警、变道辅助预警、后方交通穿行预警 (rear crossing traffic alert)、后方交通穿行制动(rear cross traffic assist with braking)和开门预警(door open warning，DOW)等场景。
图9示出了本申请实施例提供的应用场景的另一示意图。该场景为后方交通穿行预警场景。如图9所示，车辆1在行驶的过程中，通过座舱外传感器采集的数据检测到车辆3从车辆1的右后方加速超越车辆1。在车辆3进入车辆1的告警范围内且车辆3相对于车辆1的运动趋势为由东南向西北运行时，车辆1可以控制扬声器247、扬声器245和扬声器243发出声像能漂移的提示音，该提示音的声像漂移方向与车辆3相对于车辆1的运动趋势相对应。从而可以提示驾驶员目标正在从车辆1的右后方超越车辆1。
一个实施例中，可以根据用户所在的区域，从车辆1中的多个扬声器中确定该至少两个扬声器。
例如，在开门预警场景下，可以根据打开车门的用户所在的区域，从车辆1中的多个扬声器中确定该至少两个扬声器，从而控制该至少两个扬声器发生声像漂移的提示音，该提示音的声像漂移方向为车门外的目标相对于车辆1的运动趋势。
示例性的，图10示出了本申请实施例提供的扬声器分布的示意图。如图10所示，车辆1可以包括扬声器1001-1016。可以将车辆1的座舱内划分为主驾区域、副驾区域、二排左侧区域和二排右侧区域。其中，扬声器1001-1004为副驾区域内的扬声器，扬声器1005-1008为主驾区域的扬声器，扬声器1009-1012为二排右侧区域的扬声器，扬声器1013-1016为二排左侧区域的扬声器。
例如，当主驾区域的用户下车时，用户可能不会注意到主驾区域车门外移动的目标(例如，骑自行车或者摩托车的用户)。通过声像漂移的提示音可以对准备下车的用户进行提示，从而使得用户获知打开车门会存在碰撞风险。例如，当主驾区域车门外的目标从车门后方向前方行驶时，可以控制扬声器1005和扬声器1007发出声像能漂移的提示音，该提示音的声像漂移方向为从车辆1的尾部指向车辆1的头部，或者，该提示音的声像漂移方向为由扬声器1007指向扬声器1005。
一个实施例中，根据打开车门的用户所在的区域，从车辆1中的多个扬声器中确定该至少两个扬声器，从而控制该至少两个扬声器发生声像漂移的提示音，包括：根据打开车门的用户所在的区域和目标的运动趋势，从车辆1中的多个扬声器中确定该至少两个扬声器。
例如，在通过座舱内的摄像头检测到副驾区域的用户准备打开车门的操作时，可以对车辆1告警范围内的目标进行检测。当检测到有目标从副驾区域车门外的右后方向左前方靠近副驾区域车门时，可以根据目标相对于车辆1的运动趋势，从扬声器1001-1004中确定扬声器1001和扬声器1004。从而控制扬声器1001和扬声器1004发出提示音，该提示音的声像漂移方向由扬声器1001指向扬声器1004。从而副驾区域的用户通过该提示音可以确定打开车门后存在碰撞风险。或者，该提示音的声像漂移方向也可以是由扬声器1004指向扬声器1001。从而副驾区域的用户通过该提示音可以确定车门外有目标正在靠近。
图11是本申请实施例提供的另一应用场景的示意图。如图11所示，该场景为车道偏离预警(lane departure warning)场景。
车辆1可以通过座舱外的传感器采集的数据确定车辆1所在车道的标识线的信息。在车辆1从位于车道1中的中间位置向标识线1偏离时，可以控制扬声器242和扬声器243发出声像漂移的提示音。例如，该提示音的声像漂移方向可以由扬声器243指向扬声器 242，该提示音用于提示用户当前车辆正在靠近右侧的标识线；或者，该提示音的声像漂移方向可以由扬声器242指向扬声器243，该提示音用于提示用户向左打方向盘，从而使得车辆处于车道1的中间位置。
以上结合附图介绍了通过座舱内的至少两个扬声器发出声像漂移的提示音，从而使得座舱内的用户获知目标相对于车辆1的运动趋势的过程，本申请实施例并不限于此。例如，本申请实施例的技术方案还可以应用于座舱外，通过座舱外的至少两个扬声器发出声像漂移的提示音，从而对座舱外的用户进行提示。
图12示出了本申请实施例提供的另一应用场景的示意图。如图12所示，用户驾驶车辆1向车位1泊车。在通过座舱外的传感器采集的数据检测到车位1附近静止站立的用户时，可以控制座舱外的扬声器1201和扬声器1202发出声像漂移的提示音，该提示音的声像漂移方向可以由扬声器1201指向扬声器1202，这样可以使得静止站立的用户获知车辆1正在靠近自己，从而可以及时对车辆1进行避让。
一个实施例中，该车辆1中保存有运动趋势与发声装置之间的映射关系，该车辆1可以根据该映射关系以及目标相对于车辆1的运动趋势，确定该至少两个扬声器。示例性的，可以将处于车辆1的告警范围内的目标分为前方侧向穿插目标和盲区目标。前方侧向穿插目标相对于车辆1的运动趋势可以包括从车头的左侧向右侧运动或者从车头的右侧向左侧运动；盲区目标相对于车辆1的运动趋势可以包括从车辆1的左后侧加速超过车辆1或者从车辆1的右后侧加速超过车辆1。表7示出了运动趋势、发声装置与声像漂移方向之间的对关系。
