AI:智能轨迹倒车系统作为贵公司近两年的主推技术之一,请为我们详细介绍一下其功能和特点,您认为该系统最大的亮点在哪里?
殷建红先生:我们公司开发的智能轨迹倒车系统,由4部分组成,分别为专车专用的摄像头、显示屏(好帮手电子DVD主机的显示屏)、图像处理器和方向盘角度传感器。整套系统能够在显示屏上动态地显示倒车曲线,随着方向盘转动,倒车引导辅助曲线就随即转动,准确地规划倒车的轨迹。其特点可概括为如下几大方面:
1. 显示屏上显示的梯形区域(方向盘归零位)代替普通产品上的标尺线,更形象、更精确;
2. 显示屏上还显示了两条动态倒车轨迹线,这是革命性的突破,该动态倒车轨迹线实时地、准确地规划了倒车时汽车尾部运动的轨迹;
3. 配上专车专用的摄像头,摄像头安装时不需要在保险杠打洞,且安装位置隐蔽,不破坏原车外观风格,摄像头安装夹角为专车设计,将车尾的视角死区减小到最低限度,视觉效果更合理;
4. 在摄像头和显示屏之间增加了图像处理器模块,能够很好地校正桶形失真的图像,使显示屏上显示的图像和车后的实际图像基本保持一样。有了图像处理器还能在显示屏上显示半透明的辅助图标,如显示屏上显示的梯形区域,能够更逼真、更精确地规划出汽车尾部的安全无障碍区。
我认为,好帮手电子推出的智能轨迹倒车系统最大的亮点就是驾驶者在倒车时操作更简单、更安全、更舒适。更重要的就是,我们的这一系统配套车型更广。
AI:智能轨迹倒车系统在功能上与相对比较成熟的语音/可视倒车雷达系统等技术相比,您认为它们的主要区别提现在哪些方面?
殷建红先生:主要区别在以下4个方面:
1. 方向感
倒车时最难判断的是方向盘打多少合适,语音/可视倒车雷达系统是无法掌握到的,汽车在倒车时,通过发出警示声音或语音提醒车后路人,使其主动闪避,减少事故伤害;而我们推出的智能轨迹倒车系统,通过在原车上增加一个方向盘读取器,读取器角度与屏幕上的两根引导线根据角度数据给出倒车方向参照,实时准确规划倒车时汽车尾部运动的轨迹。
2. 距离感
对于复杂的驾驶环境,车主仅仅用语音/可视倒车雷达系统很难做出距离判断,而好帮手电子智能轨迹倒车系统结合车身位置参照、障碍物距离参照等技术,屏幕上显示的梯形区域代替普通产品上标尺,更形象、更标准。
3. 精度高
好帮手电子智能轨迹倒车系统采用专车专用广角镜头,并通过软件将光学误差人为校正,保证了显示的透视图像与实际环境精确一致,让显示距离与实际距离分毫不差;而语音/可视倒车雷达系统根本就不具备如此精度高的显示图象。
4. 美观度
好帮手电子智能轨迹倒车系统配上专车专用的摄像头,摄像头安装不需要破坏原车完整性与外观风格,保持了原车的美观度;而语音/可视倒车雷达系统或许不能完全地保持原车的外观风格或美观度。
AI:目前,好帮手电子的产品在汽车整车厂的配套情况如何?
殷建红先生:在前装整车配套市场,好帮手电子目前已成功地为上海汇众、江淮汽车、一汽轿车、长城汽车、长丰汽车、重庆力帆、奇瑞汽车和长安汽车等多家整车生产商提供具备竞争力的导航影音配套技术服务。另外,我公司抓住车载影音普通屏升级为TFT液晶显示屏的机会,加强产品技术的不断创新与品质提升,并针对整车厂提出了“车载影音方案咨询”服务模式,根据整车厂所生产的车型、定位以及销售价格提出相应的车载影音方案,我们还可以根据整车厂的要求为他们量身定做高性价比、优匹配度的整套车载智能影音导航解决方案。
AI:贵公司在市场开拓和用户推广方面主要采取怎样的战略?比如参加重点展会和针对主机厂用户开展技术展示等。
殷建红先生:2008年10月~2009年3月,好帮手电子赴国内长丰、吉利、吉奥、奇瑞、北汽、华晨、长城、长安、神龙、哈飞以及比亚迪共11个汽车生产厂开展技术交流活动,取得了很好的效果。在技术交流会上,智能轨迹倒车系统的现场体验得到了各汽车厂商领导的高度评价和一致认可。在2009年,我们将大力把智能轨迹倒车系统融入到前装产品中,并进一步深化进入汽车生产厂开展技术交流会,来推广展示我们出色的研发实力、成熟的技术平台以及智能轨迹倒车系统和其他前装配套产品。
Create a Completely New Era for Automobile Intelligent ElectronicsAn--Interview with Mr. Jianhong Shen, GM of OEM Dept. and Vice GM of GuangDong SanShui Coagent Electronic S&T Co., Ltd.
If comparing the technology function of intelligent track reversing system launched by Coagent with those of the relatively matured voice/visual reversing radar system, their differences are mainly shown in the following four aspects:
The first one is a sense of direction. At car back running, the most difficult to make a judgement is to determine how many degrees to be rotated for the steering wheel. It is still difficult to control the car back running just by using a voice/video system through giving out a warning sound to the passers behind the car, making them take an active action to avoid and reduce the accidents; while the intelligent track car reversing system is just adding a steering wheel reader on the panel to read out the angle data and give out the direction reference for the car back running through two guide lines according to the angle parameters, and then accurately plan a real-time movement track of the car rear end when reversing the car.

The second one is a sence of distance. In complex driving environment, it is very difficult to make a correct distance judgement for the driver just by using voice/video car reversing radar system; while the intelligent track reversing system can take the car body location as the reference or the obstructions’ distances as the reference technology to show the trapezoidal area on the screen in replacement of scale on the ordinary product, which will be more visual and more standard.
The third one is the high accuracy. Intelligent track reversing system uses a dedicated wide-angle lens for special cars, ensuring accurate consistancy of the displayed perspective image with the actual environment through a software to correct the optics errors by factitious ways, letting the displayed distance be exactly the same as the actual distance; while the voice/video car reversing radar system simply does not have such a displayed image with so high accuracy at all.
The fourth one is the aesthetics. Intelligent track reversing system is equipped with a dedicated camera for the special cars, the installation of which will not damage the integrity of the original car’s style and appearance, still keeping the original car’s aesthetics; while the voice/video car reversing radar system may not be able to fully maintain the original car’s appearance style or its aesthetics.
