Brake lamp stepped turn-on control system for enhancing braking safety

Abstract

The invention relates to the field of automobile active safety and discloses a brake lamp stepped turn-on control system for enhancing braking safety. The brake lamp stepped turn-on control system forenhancing the braking safety mainly comprises a brake lamp controller, a brake switch, an accelerator pedal acceleration sensor, a brake pedal speed sensor, a deceleration sensor, a speech promptingdevice, two common brake lamps and three groups of high level brake lamps; the brake lamp controller analyzes an obtained signal in real time, comprehensively judges a vehicle motion state, controls the speech prompting device to work, and controls the two common brake lamps and the three groups of high level brake lamps to be turned on or flash in a stepped manner to represent the braking strength of a driver; and meanwhile, when a vehicle needs to be braked, no matter the driver adopts a correct braking mode or a false braking mode, the brake lamp stepped turn-on control system for enhancingthe braking safety can both control the corresponding brake lamps to be correctly turned on or flash in a stepped manner to warn a following vehicle in time; and therefore, traffic accidents are avoided, and the vehicle running safety is enhanced.

Description

technical field [0001] The invention relates to the field of automobile active safety, in particular to a brake light graded lighting control system for improving brake safety. Background technique [0002] Brake lights (ordinary brake lights and high-position brake lights) are one of the important signal equipment of the whole vehicle, which are used to transmit the signal of braking and deceleration of the vehicle to the rear vehicles; in the traditional technology, the brake lights only use the brake switch to independently control, and can only indicate whether the vehicle is braking by turning on or off, but cannot reflect the driver's braking intensity; the subsequent step-by-step lighting of the brake lights, although it can be detected through the brake lights The graded lighting represents the driver's braking intensity, but this control system is based on the premise that the driver can take the correct braking method (correct normal braking or correct emergency br...

AI Technical Summary

Problems solved by technology

[0002] Brake lights (ordinary brake lights and high-position brake lights) are one of the important signal equipment of the whole vehicle, which are used to transmit the signal of braking and deceleration of the vehicle to the rear vehicles; in the traditional technology, the brake lights only use the brake switch to independently control, and can only indicate whether the vehicle is braking by turning on or off, but cannot reflect the driver's braking intensity; the subsequent step-by-step lighting of the brake lights, although it can be detected through the brake lights The graded lighting represents the driver's braking intensity, but this control system is based on the premise that the driver can take the correct braking method (correct normal braking or correct emergency braking), that is, when the driver takes the correct braking method according to the actual road conditions After the braking mode, the corresponding brake lights will be illuminated in grades, which ignores that in an emergency situation, the driver adopts the wrong braking mode due to unfamiliar skills, lack of experience, excessive tension or fatigue driving When the brake pedal is pressed to the bottom or the accelerator pedal is pressed by mistake)

[0003] In an emergency situation, the driver should depress the brake pedal to the bottom to achieve the maximum intensity of the brake, so that all the graded brake lights are lit, but if the driver does not depress the brake pedal to the bottom at this time, the graded light If all the moving lights cannot be turned on, that is, the brake lights are wrongly turned on; if the driver steps on the accelerator pedal by mistake at this time, the brake lights will not turn on when the brake lights are turned on in stages, that is, the brake lights are not turned on. At this time, the wrongly lit or unlit brake light will cause the rear driver to misjudge, and easily cause traffic accidents such as rear-end collisions and serial collisions, especially when the vehicle is driving at high speed and braking in an emergency.

[0004] In the existing patents whose publication numbers are CN101482243A and CN101549667A, a high-position stop lamp control system and control method that can be lighted in stages are disclosed, and they all obtain the braking deceleration of the vehicle by installing a deceleration sensor. The high-mounted brake lights can be turned on in stages, but the control conditions of this system are single and the control is not accurate enough. At the same time, it cannot solve the problem of how to control the correct step-by-step lights of the brake lights when the driver brakes incorrectly.
