Although the second type of vehicle speed limiter obviously has the advantage of actively avoiding traffic accidents, its speed limit method is relatively single and broad, and cannot fully consider the actual situation of the car's actual driving (such as road section, time, brightness, etc.), so it cannot be changed. Accurate control of vehicle speed

Embodiment Construction
[0020] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the following embodiments will specifically elaborate the automobile speed limiter based on ambient brightness of the present invention in conjunction with the accompanying drawings.
[0021] figure 1 Shown is a schematic diagram of the structure of the electronic accelerator system of an ordinary car. The accelerator pedal signal collected by the pedal sensor is directly transmitted to the electronic control unit (ECU). The electronic control unit controls the operation of the motor according to the accelerator pedal signal to realize the adjustment of the throttle. Control the speed of the car.
[0022] Such as figure 2 As shown, an automobile speed limiter 100 based on ambient brightness is connected between a pedal sensor 20 and an electronic control unit 30 .
[0023] Such as figure 2 , image 3 As shown, the vehicle speed limiter 1...

The invention provides an automobile speed limiter based on ambient brightness. An electronic control unit of the automobile is connected with a pedal sensor through a normally closed type switch. The automobile speed limiter based on the ambient brightness comprises a light sensation sensor mounted on the automobile, a signal acquisition unit connected with the light sensation sensor and an automobile speed sensor of the automobile, a setting unit, a memory unit, a processing unit connected with the signal acquisition unit, the setting unit and the memory unit, a signal output unit connected with the processing unit and an electronic control unit of the automobile, and a switching capacity control unit connected with the processing unit and the normally closed type switch. According to the automobile speed limiter based on the ambient brightness disclosed by the invention,, the automobile travelling speed can be more accurately restricted according to the ambient brightness change; especially under the situations that the illumination intensity is weak of nighttime travelling, tunnel travelling and the like, the occurrence rate of traffic accidents can be effectively reduced, so that overspeed violation and overspeed fine are reduced, the automobile maintenance cost expense can be saved, and oil consumption are reduced.
Description
technical field [0001] The invention belongs to the technical field of automobile speed limiters, and in particular relates to an automobile speed limiter based on ambient brightness. Background technique [0002] With the development of my country's economy and the improvement of people's living standards, more and more families own cars. Although cars provide great convenience for people's travel, many people will speeding while driving, and speeding is very dangerous. May cause a traffic accident. [0003] Currently, in order to avoid speeding, car speed limiters are installed on cars. Existing car speed limiters are usually divided into two categories: one is to issue a voice alarm to remind the driver to slow down when the vehicle is overspeed; the other is to issue instructions through the on-board computer to force the vehicle to be controlled after the vehicle exceeds the speed limit driving speed without stalling. Although the second type of vehicle speed limiter ...
