A system for changing the brake by stepping on the accelerator by mistake

Abstract

The invention discloses a system for changing the brake by accidentally stepping on the accelerator, which comprises: a linkage arm and an accelerator pedal arm installed in the vehicle frame in a manner that can be automatically returned in sequence; an iron block is installed on the induction rod of the accelerator sensor; Install the suction cup electromagnet coil for absorbing the iron block when energized, and the linkage arm is connected with the brake pump push rod; the rotating device connected with the linkage arm is used to drive the linkage arm to rotate downward; it is used to detect the speed of the accelerator pedal The control device is electrically connected to the suction cup electromagnet coil and the rotating device respectively. The control device has a preset upper limit value of the accelerator pedal speed. The electrical connection of the coil is electrically connected to the rotating device at the same time, and the rotating device drives the linkage arm to rotate downwards to drive the brake pump push rod to work. The invention can automatically convert the accelerator into a brake when the accelerator is stepped on by mistake during emergency braking, and has simple structure and low cost.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a brake-changing system for mistakenly stepping on the accelerator. Background technique [0002] The accelerator and brake pedals are arranged adjacent to each other on the car, and both are controlled by the right foot. When braking in an emergency, a skilled driver may be able to reflexively move his foot to the brake pedal and then step on it, but it is inevitable that he will step on it by mistake. For novice drivers, it is difficult to form this conditioned reflex due to the short driving time. Due to the suddenness of the incident, the novice is easy to mistake the accelerator for the brake and directly step on it, thus causing a traffic accident. [0003] Based on this, there have been many methods for preventing accidental pedaling of the brakes, such as arranging the brake pedal and the accelerator pedal at a large distance, and controlling them separately throug...

Problems solved by technology

For novice drivers, due to the short driving time, it is difficult to form this conditioned reflex. Due to the sudden occurrence of the accident, novices can easily mistake the accelerator for the brake and directly step on it, resulting in traffic accidents.

[0003] Based on this, there have been many methods for preventing accidental stepping on the accelerator, such as arranging the brake pedal and the accelerator pedal at a large distance, and controlling them separately through the left and right feet. Will step on the accelerator by mistake, can't really play a role

The method that has been applied to existing vehicles and has a good effect is to perform automatic braking control through the controller and laser sensor. The laser sensor is used to detect the object in front. When it detects that the object in front is within a certain distance from the front of the vehicle, it will automatically brake But the system is expensive and is common in high-end cars
