The invention provides an automobile speed limit setting device and a speed limit mechanism. The device comprises a switch, a coarse tuning knob, a fine tuning knob, a loudspeaker, a display screen, a microcontroller and a data interface. The switch controls the on and off of the device; the speed limiting value can be roughly adjusted by the coarse tuning knob; the fine tuning knob can finely adjust the speed limit value; the loudspeaker can give out prompt tone and voice broadcast; the display screen displays the speed limit value; and the microcontroller determines a speed limit value according to the adjustment conditions of the coarse tuning knob and the fine tuning knob, and sends the speed limit value to the vehicle-mounted computer ECU through the data interface. The automobile speed limit setting device is installed at the positions such as an automobile central control panel, a driver can rapidly set the speed limit value through one-hand operation, and excessive attention cannot be distracted. According to the device, a ceiling speed limiting mechanism is adopted, the vehicle-mounted computer ECU controls the maximum speed of the vehicle not to exceed the speed limiting value in an electronic or mechanical mode, the driver does not need to frequently pay attention to the speed of an instrument panel due to overspeed, and the driving experience is greatly improved.
本发明提出一种汽车限速设置装置及限速机制。该装置包括:开关、粗调旋钮、微调旋钮、扬声器、显示屏、微控制器、数据接口。开关控制该装置的开启和关闭;粗调旋钮可粗略调节限速值;微调旋钮可细微调节限速值;扬声器可发出提示音和语音播报;显示屏显示限速值;微控制器根据粗调旋钮和微调旋钮的调节情况确定限速值,并通过数据接口将限速值发送给车载电脑ECU。汽车限速设置装置安装在汽车中控面板等位置,驾驶员可单手操作迅速设置好限速值,且不会分散过多注意力。该装置采用顶棚限速机制,车载电脑ECU通过电子或机械方式控制汽车最高速度不超过限速值,驾驶员无需再因担心超速而频繁关注仪表盘速度,极大提高了驾驶体验。
