Reminding device for preventing pedal misoperation by driver

Abstract

The invention discloses a reminding device for preventing pedal misoperation by a driver. The reminding device comprises an electronic throttle control system, an electromyography information collection module, a misoperation judgment module and a voice prompt module. The electromyography information collection module is used for collecting surface electromyography signals of main force generation muscles in the pedal treading process by the right leg of the driver in real time. The misoperation judgment module judges whether the driver has a pedal misapplication operation or not according to the driver muscle surface electromyography signals collected by the electromyography information collection module and pedal position change information sent by a pedal displacement sensor and further sends control signals to the voice prompt module and an ECU according to the judgment result. The voice prompt module is controlled by the misoperation judgment module to give out a voice alarm. The ECU receives control signals of the misoperation judgment module and decides whether the pedal movement needs to be responded or not. By means of the reminding device, whether the driver treads a pedal mistakenly or not can be distinguished more accurately by measuring the electromyography signals of the right leg muscles, the voice alarm is given out, and delayed response is made to avoid traffic accidents.

Description

technical field [0001] The invention relates to an automobile auxiliary equipment, in particular to a reminder device for preventing the driver from misoperation of the pedal. Background technique [0002] With the development of the economy and the progress of the society, the number of automobiles in our country has increased year by year, and some problems have followed. Most drivers in our country are still new drivers with less than three years of driving experience. Many accidents are caused by novice drivers’ inattention or substandard driving skills in the process of driving a car. And it is also controlled by the right foot. In some cases, the accelerator is mistakenly used as a brake, which may cause traffic accidents. Therefore design the device that prevents pedal misoperation is very necessary, and existing patent generally all is only by measuring the power of stepping on the pedal or the size of acceleration to judge whether to step on by mistake, and directl...

Problems solved by technology

The accuracy of this type of discrimination is low. When the driver performs normal operations, it may be judged that the driver stepped on the accelerator by mistake, causing the car to be forcibly braked during the process of overtaking or changing lanes. This poses a great safety hazard.
