An automatic resettable automobile accelerator pedal anti-misstepping system and its control method

Abstract

The invention discloses a self-resetting system for preventing an automobile accelerator pedal from being stepped by mistake as well as a control method of the system. The automobile comprises the accelerator pedal and a speed-measuring gear; and the system for preventing the accelerator pedal from being stepped by mistake comprises an acquisition module, an MCU module, an execution module and a power supply module. According to the self-resetting system for preventing the automobile accelerator pedal from being stepped by mistake as well as the control method of the system, an information acquisition module uses a photoelectric coded disk speed-measuring sensor fixed on the end face of the speed-measuring gear, and the sensor measures the rotating speed of the speed-measuring gear insteadof directly measuring the speed information of the accelerator pedal, so the automobile has high anti-interference capability in the complicated driving environment and the reliability of the acquired speed data is greatly improved; meanwhile, whether the pedal is stepped by mistake or not is comprehensively judged by barrier information provided by an ultrasonic radar, so that the misjudgment conditions are greatly reduced; furthermore, the existing operating habit does not need to be changed, so that operation of the driver is facilitated.

Description

technical field [0001] The invention relates to the field of automobile auxiliary safety driving, in particular to an automatic resettable automobile accelerator pedal anti-misstepping system and a control method thereof. Background technique [0002] At present, with the development of my country's economy and the improvement of industrialization level, cars have entered thousands of households and become one of the indispensable means of transportation in people's lives. Of course, there are more and more car accidents, some of which are caused by drivers stepping on the gas pedal by mistake. When the car is running normally, step on the gas pedal with your right foot. When the car wants to slow down or stop, you need to move your right foot from the gas pedal to the brake pedal and press the brake pedal hard to brake. When it comes to an emergency, because people’s psychological tension often leads to inability to concentrate highly, it is easy to make operational mistak...

AI Technical Summary

Problems solved by technology

Among them, 12.6% of the accidents were caused by drivers accidentally stepping on the accelerator pedal due to unskilled skills, lack of concentration, poor health, excessive stress and fatigue, and the influence of alcohol or drugs.

Aiming at such accidents, relevant researchers at home and abroad have done a lot of research work, and the results obtained include: the accelerator pedal and the brake pedal are combined into one, but this kind of pedal destroys the original mechanical operation structure of the car and changes the existing It is difficult for the driver to adapt to the driving habits of the driver; the emergency braking mechanical remedial device for the accidental stepping on the accelerator pedal of the car does not change the existing operating habits, but there are problems such as difficult installation, insufficient response sensitivity and too complicated structure; using radio or ultrasonic The distance measuring method prevents the device from stepping on the accelerator pedal by mistake. This system has high requirements on obstacles, and ordinary obstacles may not be effective, and the response is slow
