具体实施方式Detailed ways
以下通过实施例对本发明的技术方案进行详细的说明，以下的实施例仅是示例性的，仅能用来解释和说明本发明的技术方案，而不能解释为是对本发明的技术方案的限制。The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.
本申请的技术方案是利用现有的车辆速度传感器对车辆的即时速度的检测信号，在本技术方案中，车辆速度传感器检测的即时速度的信号传递给车身控制器，在本申请的其它实施例中，车辆速度传感器检测的即时速度信号也可以发送到CAN总线或者其它控制模块，本技术方案是对即时速度的信号的利用，并不关心即时速度信号发送给哪个模块，同样的，仪表盘上的仪表速度信号通常与车身控制器信号连接，以接收通过车身控制器传输的车辆速度传感器检测的即时速度信号。The technical solution of the present application is to use the existing vehicle speed sensor to detect the instantaneous speed of the vehicle. In this technical solution, the signal of the instantaneous speed detected by the vehicle speed sensor is transmitted to the vehicle body controller. In other embodiments of the application Among them, the instant speed signal detected by the vehicle speed sensor can also be sent to the CAN bus or other control modules. This technical solution uses the instant speed signal and does not care which module the instant speed signal is sent to. Similarly, the instrument panel The instrument speed signal is usually connected with the body controller signal to receive the instant speed signal detected by the vehicle speed sensor transmitted by the body controller.
在本技术方案中，车身控制器接收到的即时车速信号进行处理，即以最简单的差值法进行计算相邻两个即时速度信号的值，在此以绝对值表示，当相邻速度变化值的绝对值≥设定值时，本技术方案中，设定值可以根据需要进行设定，比如3m/s、5m/s、10m/s、15m/s等等，车身控制器将车辆速度变化后的即时的数值传递给显示装置，由显示装置显示在车辆的尾部，这样，后车就能够清楚的差别前车的车速变化情况，并具此进行相应的控制。In this technical solution, the instant vehicle speed signal received by the body controller is processed, that is, the value of two adjacent instant speed signals is calculated by the simplest difference method, which is expressed in absolute value here. When the adjacent speed changes When the absolute value of the value ≥ the set value, in this technical solution, the set value can be set according to needs, such as 3m/s, 5m/s, 10m/s, 15m/s, etc., the vehicle body controller will set the vehicle speed The changed real-time value is transmitted to the display device, which is displayed on the rear of the vehicle, so that the rear vehicle can clearly distinguish the speed change of the front vehicle, and carry out corresponding control accordingly.
在本申请中，显示装置为显示屏或其它类似的装置，并且安装在车辆后挡风玻璃上或车辆尾部的相应的比较显著的位置，以便于后车观察，或后车的探测器检测。In this application, the display device is a display screen or other similar devices, and is installed on the rear windshield of the vehicle or at a relatively prominent position at the rear of the vehicle, so as to facilitate observation of rear vehicles or detection by detectors of rear vehicles.
在本申请的其它实施例中，还可以将显示装置与仪表速度信号连接，这样仪表上显示的速度同步在显示装置上显示，以便于后车的观察或探测器的检测。In other embodiments of the present application, the display device can also be connected to the instrument speed signal, so that the speed displayed on the instrument is synchronously displayed on the display device, so as to facilitate the observation of the vehicle behind or the detection of the detector.
为了后方车辆能够快速、准确的识别到前车的速度信息，避免对前车状态的误判导致碰撞等情况的发生，有必要在显示装置上设置不同字体颜色，比如，减速状态时使用红色字体颜色，在加速时使用绿色字体颜色等，以保证识别更加清晰。In order for the vehicle behind to quickly and accurately identify the speed information of the vehicle in front, and to avoid misjudgment of the state of the vehicle in front and lead to collisions, it is necessary to set different font colors on the display device, for example, use red fonts when decelerating Color, use green font color, etc. when accelerating, to ensure clearer recognition.
在本申请的其它实施例中，显示装置上设置有报警器，当车辆的速度变化值的绝对值超过预警值时，此处的预警值大于设定值，特别是针对急刹车时的速度变化，显示装置在显示即时速度的同时，还启动报警装置，以提示后车注意，避免出现碰撞等事故。In other embodiments of the present application, the display device is provided with an alarm. When the absolute value of the speed change value of the vehicle exceeds the warning value, the warning value here is greater than the set value, especially for the speed change during sudden braking. , when the display device displays the instant speed, it also activates the alarm device to remind the car behind to pay attention to avoid collisions and other accidents.
在本申请的其它实施例中，当车辆由静止开始启动时，也包括由怠速状态开始加速时，此情况下，即使是速度变化值的绝对值小于设定值，车身控制器也将即时速度传递给显示装置，同时启动报警器，除了避免碰撞外，还能够降低其它的安全风险。In other embodiments of the present application, when the vehicle starts from rest, it also includes when it starts to accelerate from the idling state. Passing to the display device and activating the alarm at the same time, in addition to avoiding collisions, other safety risks can also be reduced.
