Problems solved by technology

[0005] The purpose of the present invention is to provide a comprehensive auxiliary braking control technology for vehicle speed and vehicle distance, which can automatically calculate the distance between the current vehicle and the obstacle in front by automatically identifying the distance between the current vehicle and the obstacle in front and the speed of the current vehicle in real time. and according to the driving time, the vehicle brake auxiliary device can be automatically activated in real time, which can not only ensure the normal refueling and driving when there is no obstacle in front of the vehicle, but also ensure the driving efficiency and avoid the rear-end collision of the vehicle, which overcomes the existing single auxiliary brake lack of technology

Embodiment example 1

[0061] Refer to attached figure 1 , 8 , 9, 10, the distance signal between the current vehicle and the obstacle in front is collected in real time through the distance sensor [1], the driving speed signal of the current vehicle is collected in real time through the speed sensor [2], and the signal processing controller [6] collects in real time The received distance and speed signals are comprehensively processed to automatically calculate the driving time between the current vehicle and the obstacle in front, and determine whether to activate the brake assist device according to the driving time [8].

[0062] If the driving time is less than or equal to a certain set value, the signal processing controller [6] outputs the brake control signal, the normally open relay [7] acts, the corresponding contact closes, the normally open oil circuit solenoid valve [9] starts, the oil circuit Close, the whistle horn [10] sounds automatically, the high beam [11] flashes automatically, a...

Embodiment example 2

[0065] Refer to attached figure 1 , 6 , 7, 8, 9, 10, the traffic light information in front of the vehicle is collected in real time through the traffic light sensing system [5], the signal processing controller [6] processes the collected traffic light information in real time, and determines whether to start the brake according to the traffic light information Auxiliary device [8].

[0066] If there is a red light in front of the current vehicle, the signal processing controller [6] outputs a brake control signal, the normally open relay [7] acts, the corresponding contact is closed, the normally open oil circuit solenoid valve [9] is activated, the oil circuit is closed, and the horn sounds The horn [10] sounds automatically, the high beam [11] flashes automatically, at the same time, the motor [21] of the brake assist device [8] rotates, the power disc [22] is rotated and the brake pedal [23] is pressed down, and the vehicle starts to brake. Move until the vehicle stops ...

Embodiment example 3

[0069] Refer to attached figure 1 , 2, 3, 8, 9, 10, collect the curve information in front of the vehicle in real time through the curve sensor system [3], collect the current vehicle speed signal in real time through the speed sensor [2], and the signal processing controller [6] in real time Process the collected curve signal and speed signal, and determine whether to start the brake assist device according to the curve signal and speed signal [8].

[0070] If there is a curve ahead of the current vehicle, and the current vehicle speed is greater than a certain set value, the signal processing controller [6] outputs the brake control signal, the normally open relay [7] acts, the corresponding contact is closed, and the normally open oil circuit solenoid valve [9] starts, the oil circuit is closed, the horn [10] sounds automatically, the high beam [11] flashes automatically, at the same time, the motor [21] of the brake assist device [8] rotates, and the rotary power disc [22...

Abstract

The invention discloses an intelligent auxiliary brake system of a vehicle. The intelligent auxiliary brake system consists of a distance sensor, a speed sensor, a curve sensing system, a slope sensing system, a traffic light sensing system, a signal process controller, a normally opening relay, an auxiliary brake device, a normally opening oil path electromagnetic valve, whistle horns, a high beam, a display and a speaker. The intelligent auxiliary brake system automatically identifies the distance between an existing vehicle and a front vehicle and the speed of the existing vehicle, and automatically computes the traveling time between the existing vehicle and the front vehicle so as to automatically start the auxiliary brake device of the vehicle and avoid the vehicle rear-end accident. Simultaneously, the intelligent auxiliary brake system can further automatically identify a traffic light, a curve and a slope in the front of the vehicle, and avoids dangerous driving actions that the vehicle runs the red light, runs over the curve at high speed and runs the slope at high speed.

Description

technical field [0001] The invention relates to a vehicle intelligent auxiliary braking system, in particular to a real-time automatic recognition of the distance between the current vehicle and the obstacle in front and the speed of the current vehicle, automatically calculating the driving time between the current vehicle and the obstacle in front, and According to the driving time, the vehicle's brake assist device is automatically activated in real time to avoid the vehicle's intelligent auxiliary brake system from rear-end collisions. Background technique [0002] With the continuous improvement of living standards, the number of car ownership is also increasing. While cars bring great convenience to people's life and work, they also continue to bring people traffic safety problems during travel. In the process of traveling by car, due to lack of concentration, excessive vehicle speed, and inaccurate judgment of the distance from the vehicle in front, traffic rear-end s...
