Device for realizing emergency braking function when driver mistakenly steps on accelerator

Abstract

The invention relates to a device for realizing an emergency braking function when a driver mistakenly steps on an accelerator, the end A of a lever is close to an electromagnetic coil, the end B of the lever is close to a brake rod of a brake pedal, a spring is connected to the side, away from a fulcrum and close to the end B, of the lever, and the electromagnetic coil is powered on and powered off through a coil control circuit; when the electromagnetic coil is energized, the electromagnetic coil attracts the A end of the lever, the spring is in a contraction state, the end B of the lever does not make contact with the brake rod, when the electromagnetic coil is disconnected with the end A of the lever when the electromagnetic coil is powered off, the spring is in a stretching state, the end B of the lever makes contact with the brake rod, and the end B of the lever can continuously press the brake rod to move downwards. A self-resetting pressure travel switch K1 is installed at the bottom of an accelerator pedal, an acceleration sensor IC1 is installed on the accelerator pedal, and when the accelerator pedal is pressed downwards, the self-resetting pressure travel switch K1 is stepped on and switched on. If the accelerator pedal is mistakenly used as a brake, the emergency braking function can be achieved, and safety accidents are avoided.

Description

technical field [0001] The invention relates to a brake device for stepping on the accelerator by mistake, in particular to a device for realizing the emergency braking function by the driver of a car by stepping on the accelerator by mistake, and belongs to the technical field of vehicle safety driving. Background technique [0002] When driving a car, if a driver encounters a sudden emergency, he needs to step on the brakes for emergency braking. However, due to emotional tension, many drivers (especially novices) often mistake the accelerator pedal for the brake pedal and slam it to the end. As a result, instead of stopping the car, the car accelerated and rushed forward instead, resulting in a serious traffic accident. Generally speaking, car manufacturers will make the brake pedal larger than the accelerator pedal to distinguish them, but this method is not very safe. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the pres...

[0002] When driving a car, if a driver encounters a sudden emergency, he needs to step on the brakes for emergency braking. However, due to emotional tension, many drivers (especially novices) often mistake the accelerator pedal for the brake pedal and slam it to the end. As a result, instead of stopping the car, it accelerated the car and rushed forward, resulting in a serious traffic accident.

Generally speaking, car manufacturers will make the brake pedal larger than the accelerator pedal to distinguish them, but this method is not very safe.
