[0032] Figure 1It is a logical structure block diagram of an auxiliary braking system of a vehicle of the present invention, including a radar module 1, a control module 2, a power module 3 and an electromagnet module 4, wherein the output end of the radar module 1 is connected to the input end of the control module 2; the output end of the control module 2 is connected to the input end of the power module 3; the output end of the power module 3 is connected to the input end of the electromagnet module 4. Among them, the radar module 1 includes a first radar and a second radar, the electromagnet module 4 includes a first electromagnet and a second electromagnet, the input end of the control module 2 is respectively connected to the output end of the first radar and the output end of the second radar; the output end of the power module 3 is respectively connected to the input end of the first electromagnet and the input end of the second electromagnet. In addition, the control module 2 is connected to the first radar and the second radar via a CAN line; the power module 3 is connected to the first electromagnet and the second electromagnet via a hard line.

[0033] Combine the following Figure 1 The working principle of the auxiliary braking system of the vehicle of the present invention is as follows:

[0034] During the driving process of the vehicle, the distance between the vehicles is monitored by the radar module 1 and the monitored distance information between the vehicles is input to the control module 2; the control module 2 determines whether the distance between the vehicles is less than the first distance threshold and controls the opening and closing of the power module 3; when the control module 2 determines that the distance between the vehicles is less than the first distance threshold, the control module 2 controls the power module 3 to turn on; at the same time, the control module 2 controls the power module 3 to increase the current input to the electromagnet module 4; when the control module 2 determines that the distance between the vehicles is not less than the first distance threshold, the control module 2 controls the power module 3 not to turn on. Specifically, during the driving process of the vehicle, the distance between the vehicle and the vehicle directly in front of the vehicle is monitored in real time by the first radar, and the distance information between the vehicle and the vehicle directly in front of the vehicle is input to the control module 2, and the distance between the vehicle and the vehicle directly behind the vehicle is monitored by the second radar in real time, and the distance information between the vehicle and the vehicle directly behind the vehicle is input to the control module 2. After the control module 2 receives the distance information between the vehicle and the vehicle directly in front of the vehicle and the distance information between the vehicle and the vehicle directly behind the vehicle, the control module 2 will determine whether the distance between the vehicle and the vehicle directly in front of the vehicle is less than the first distance threshold through the distance information between the vehicle and the vehicle directly in front of the vehicle. The control module 2 will determine whether the distance between the vehicle and the vehicle directly behind the vehicle is less than the first distance threshold through the distance information between the vehicle and the vehicle directly behind the vehicle. If the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is not less than the first distance threshold, and determines that the distance between the vehicle and the vehicle directly behind the vehicle is not less than the first distance threshold, the control module 2 controls the power module 3 not to turn on; if the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is less than the first distance threshold, or determines that the distance between the vehicle and the vehicle directly behind the vehicle is less than the first distance threshold, or determines that the distance between the vehicle and the vehicle directly in front of the vehicle and the distance between the vehicle and the vehicle directly behind the vehicle are both less than the first distance threshold, the control module 2 controls the power module 3 to turn on to input current to the electromagnet module 4, that is, the control module 2 controls the power module 3 to turn on to input current to the first electromagnet and the second electromagnet.Among them, the first electromagnet is arranged at the head of the vehicle, and the second electromagnet is arranged at the rear of the vehicle. When the power module 3 energizes the first electromagnet and the second electromagnet, the direction of the current flowing through the first electromagnet is opposite to the direction of the current flowing through the second electromagnet. When the power module 3 inputs current, a repulsive force will be generated between the magnetic poles of the first electromagnet at the head of the vehicle and the magnetic poles of the second electromagnet at the rear of the vehicle directly in front of the vehicle. A repulsive force will also be generated between the magnetic poles of the second electromagnet at the rear of the vehicle and the magnetic poles of the first electromagnet at the head of the vehicle directly behind the vehicle, thereby realizing auxiliary vehicle braking, that is, the repulsive force generated between the same magnetic poles of different electromagnets can assist vehicle braking. After the control module 2 controls the power module 3 to be turned on, the first radar will continue to monitor the distance between the vehicle and the vehicle directly in front of the vehicle, and input the distance information between the vehicle and the vehicle directly in front of the vehicle to the control module 2. The second radar will continue to monitor the distance between the vehicle and the vehicle directly behind the vehicle, and input the distance information between the vehicle and the vehicle directly behind the vehicle to the control module 2. The control module 2 will determine whether the distance between the vehicle and the vehicle directly in front of the vehicle is getting smaller and smaller through the distance information between the vehicle and the vehicle directly in front of the vehicle, and the control module 2 will determine whether the distance between the vehicle and the vehicle directly behind the vehicle is getting smaller and smaller through the distance information between the vehicle and the vehicle directly behind the vehicle. If the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is getting smaller and smaller, the control module 2 will control the power module 3 to increase the magnitude of the current input to the first electromagnet and the second electromagnet, and when the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is equal to the second distance threshold, the current input to the first electromagnet and the second electromagnet by the power module 3 is just increased to the maximum current that the first electromagnet and the second electromagnet can withstand; if the control module 2 determines that the distance between the vehicle and the vehicle directly behind the vehicle is getting smaller and smaller, the control module 2 will control the power module 3 to increase the magnitude of the current input to the first electromagnet and the second electromagnet, and when the control module 2 determines that the distance between the vehicle and the vehicle directly behind the vehicle is equal to the second distance threshold, the current input to the first electromagnet and the second electromagnet by the power module 3 is just increased to the maximum current that the first electromagnet and the second electromagnet can withstand, thereby assisting the braking to prevent the vehicle from colliding with the vehicle in front, and assisting the braking to prevent the vehicle behind from colliding with the vehicle. Thus, the repulsive force generated between the same magnetic poles of different electromagnets is used to assist the vehicle braking. Moreover, the above braking principle has nothing to do with temperature and oil. When the vehicle's brake pads are too hot or the brake lines are leaking oil, it can still provide braking force for the vehicle, thereby increasing the reliability and safety of the vehicle and effectively avoiding the occurrence of collision accidents.

[0035] Figure 2The present invention is a flowchart of a vehicle auxiliary braking method, the method comprising the following steps:

[0036] S1: Radar module 1 monitors the distance between vehicles and inputs the distance information between the monitored vehicles to control module 2; that is, corresponding Figure 2 S1 in. Specifically, during the driving process of the vehicle, the distance between the vehicle and the vehicle directly in front of the vehicle is monitored in real time by the radar module 1, and the distance between the vehicle and the vehicle directly behind the vehicle is monitored in real time by the radar module 1, and the distance information between the vehicle and the vehicle directly in front of the vehicle and the distance information between the vehicle and the vehicle directly behind the vehicle are input into the control module 2 through the radar module 1. More specifically, during the driving process of the vehicle, the distance between the vehicle and the vehicle directly in front of the vehicle is monitored in real time by the first radar, and the distance information between the vehicle and the vehicle directly in front of the vehicle is input into the control module 2. The distance between the vehicle and the vehicle directly behind the vehicle is monitored in real time by the second radar, and the distance information between the vehicle and the vehicle directly behind the vehicle is input into the control module 2.

[0037] S2: Control module 2 determines whether the distance between the vehicles is less than the first distance threshold. If so, it proceeds to S3; if not, it proceeds to S5; that is, corresponding to Figure 2 Specifically, after the control module 2 receives the distance information between the vehicle and the vehicle directly in front of the vehicle and the distance information between the vehicle and the vehicle directly behind the vehicle, the control module 2 determines whether the distance between the vehicle and the vehicle directly in front of the vehicle is less than the first distance threshold through the distance information between the vehicle and the vehicle directly in front of the vehicle, and the control module 2 determines whether the distance between the vehicle and the vehicle directly behind the vehicle is less than the first distance threshold through the distance information between the vehicle and the vehicle directly behind the vehicle. If the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is not less than the first distance threshold, and determines that the distance between the vehicle and the vehicle directly behind the vehicle is not less than the first distance threshold, then enter S5; if the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is less than the first distance threshold, or determines that the distance between the vehicle and the vehicle directly behind the vehicle is less than the first distance threshold, or determines that the distance between the vehicle and the vehicle directly in front of the vehicle and the distance between the vehicle and the vehicle directly behind the vehicle are both less than the first distance threshold, then enter S3.

[0038] S3: Control module 2 controls power module 3 to turn on; Figure 2S3 in. Specifically, the control module 2 controls the power module 3 to turn on to input current to the electromagnet module 4, and more specifically, the control module 2 controls the power module 3 to turn on to input current to the first electromagnet and the second electromagnet. Wherein, the first electromagnet is arranged at the head of the vehicle, and the second electromagnet is arranged at the rear of the vehicle, and when the power module 3 energizes the first electromagnet and the second electromagnet, the direction of the current flowing through the first electromagnet is opposite to the direction of the current flowing through the second electromagnet. At this time, a repulsive force will be generated between the magnetic poles of the first electromagnet at the head of the vehicle of the vehicle and the magnetic poles of the second electromagnet at the rear of the vehicle directly in front of the vehicle of the vehicle, and a repulsive force will also be generated between the magnetic poles of the second electromagnet at the rear of the vehicle of the vehicle and the magnetic poles of the first electromagnet at the head of the vehicle directly behind the vehicle of the vehicle, thereby realizing auxiliary vehicle braking. That is, the repulsive force generated between the same magnetic poles of different electromagnets can assist vehicle braking.

[0039] S4: The control module 2 controls the power module 3 to increase the current input to the electromagnet module 4; that is, Figure 2 S4 in. Specifically, after the control module 2 controls the power module 3 to be turned on, the first radar will continue to monitor the distance between the vehicle and the vehicle directly in front of the vehicle, and input the distance information between the vehicle and the vehicle directly in front of the vehicle to the control module 2, and the second radar will continue to monitor the distance between the vehicle and the vehicle directly behind the vehicle, and input the distance information between the vehicle and the vehicle directly behind the vehicle to the control module 2. The control module 2 will determine whether the distance between the vehicle and the vehicle directly in front of the vehicle is getting smaller and smaller through the distance information between the vehicle and the vehicle directly in front of the vehicle, and the control module 2 will determine whether the distance between the vehicle and the vehicle directly behind the vehicle is getting smaller and smaller through the distance information between the vehicle and the vehicle directly behind the vehicle. If the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is getting smaller and smaller, the control module 2 will control the power module 3 to increase the magnitude of the current input to the first electromagnet and the second electromagnet, and when the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is equal to the second distance threshold, the current input to the first electromagnet and the second electromagnet by the power module 3 is just increased to the maximum current that the first electromagnet and the second electromagnet can withstand; if the control module 2 determines that the distance between the vehicle and the vehicle directly behind the vehicle is getting smaller and smaller, the control module 2 will control the power module 3 to increase the magnitude of the current input to the first electromagnet and the second electromagnet, and when the control module 2 determines that the distance between the vehicle and the vehicle directly behind the vehicle is equal to the second distance threshold, the current input to the first electromagnet and the second electromagnet by the power module 3 is just increased to the maximum current that the first electromagnet and the second electromagnet can withstand. That is, the vehicle braking can be assisted by the repulsive force generated between the same magnetic poles of different electromagnets.

[0040] S5: Control module 2 controls power module 3 not to start; Figure 2 Specifically, when the control module 2 determines in S1 that the distance between the vehicle and the vehicle directly in front of the vehicle is not less than the first distance threshold, and determines that the distance between the vehicle and the vehicle directly behind the vehicle is not less than the first distance threshold, the control module 2 controls the power module 3 not to turn on.

[0041] In addition, when the vehicle is parked and in a ready state, and the brake pedal is in a braking state, the control module 2 controls the power module 3 to input the maximum current that the first electromagnet and the second electromagnet can withstand to the first electromagnet and the second electromagnet, which can assist the vehicle in braking better and greatly improve the safety of the vehicle during braking.

[0042] In this specific embodiment, the first distance threshold is 100 meters and the second distance threshold is 50 meters. However, the first distance threshold and the second distance threshold are not limited to 100 meters and 50 meters respectively, but can be adjusted according to specific needs and specific circumstances; the control module 2 can adopt a microcontroller (MCU); the first radar and the second radar can both adopt millimeter wave radar or laser radar.

[0043] The present invention also provides a vehicle, which is equipped with the above-mentioned vehicle auxiliary braking system and is controlled by the above-mentioned vehicle auxiliary braking method.

[0044] Furthermore, the present invention is applicable to a case where the host vehicle, the vehicle directly in front of the host vehicle, and the vehicle directly behind the host vehicle are all equipped with the above-mentioned vehicle auxiliary braking system.

[0045] Functions and Effects of the Embodiments

[0046] During the driving process of the vehicle, the distance between the vehicle and the vehicle directly in front of the vehicle is monitored in real time by the first radar, and the distance information between the vehicle and the vehicle directly in front of the vehicle is input into the control module 2. The distance between the vehicle and the vehicle directly behind the vehicle is monitored in real time by the second radar, and the distance information between the vehicle and the vehicle directly behind the vehicle is input into the control module 2. After the control module 2 receives the distance information between the vehicle and the vehicle directly in front of the vehicle and the distance information between the vehicle and the vehicle directly behind the vehicle, the control module 2 will determine whether the distance between the vehicle and the vehicle directly in front of the vehicle is less than the first distance threshold through the distance information between the vehicle and the vehicle directly in front of the vehicle, and the control module 2 will determine whether the distance between the vehicle and the vehicle directly behind the vehicle is less than the first distance threshold through the distance information between the vehicle and the vehicle directly behind the vehicle. If the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is not less than the first distance threshold, and determines that the distance between the vehicle and the vehicle directly behind the vehicle is not less than the first distance threshold, the control module 2 controls the power module 3 not to turn on; if the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is less than the first distance threshold, or determines that the distance between the vehicle and the vehicle directly behind the vehicle is less than the first distance threshold, or determines that the distance between the vehicle and the vehicle directly in front of the vehicle and the distance between the vehicle and the vehicle directly behind the vehicle are both less than the first distance threshold, the control module 2 controls the power module 3 to turn on to input current to the electromagnet module 4, that is, the control module 2 controls the power module 3 to turn on to input current to the first electromagnet and the second electromagnet. Among them, the first electromagnet is arranged at the head of the vehicle, and the second electromagnet is arranged at the rear of the vehicle. When the power module 3 energizes the first electromagnet and the second electromagnet, the direction of the current flowing through the first electromagnet is opposite to the direction of the current flowing through the second electromagnet. When the power module 3 inputs current, a repulsive force will be generated between the magnetic poles of the first electromagnet at the head of the vehicle and the magnetic poles of the second electromagnet at the rear of the vehicle directly in front of the vehicle. A repulsive force will also be generated between the magnetic poles of the second electromagnet at the rear of the vehicle and the magnetic poles of the first electromagnet at the head of the vehicle directly behind the vehicle, thereby realizing auxiliary vehicle braking, that is, the repulsive force generated between the same magnetic poles of different electromagnets can assist vehicle braking. After the power module 3 is turned on by the control module 2, the first radar will continue to monitor the distance between the vehicle and the vehicle directly in front of the vehicle, and input the distance information between the vehicle and the vehicle directly in front of the vehicle into the control module 2. The second radar will continue to monitor the distance between the vehicle and the vehicle directly behind the vehicle, and input the distance information between the vehicle and the vehicle directly behind the vehicle into the control module 2.The control module 2 will determine whether the distance between the vehicle and the vehicle directly in front of the vehicle is getting smaller through the distance information between the vehicle and the vehicle directly in front of the vehicle. The control module 2 will determine whether the distance between the vehicle and the vehicle directly behind the vehicle is getting smaller through the distance information between the vehicle and the vehicle directly behind the vehicle. If the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is getting smaller and smaller, the control module 2 will control the power module 3 to increase the magnitude of the current input to the first electromagnet and the second electromagnet, and when the control module 2 determines that the distance between the vehicle and the vehicle directly in front of the vehicle is equal to the second distance threshold, the current input to the first electromagnet and the second electromagnet by the power module 3 is just increased to the maximum current that the first electromagnet and the second electromagnet can withstand; if the control module 2 determines that the distance between the vehicle and the vehicle directly behind the vehicle is getting smaller and smaller, the control module 2 will control the power module 3 to increase the magnitude of the current input to the first electromagnet and the second electromagnet, and when the control module 2 determines that the distance between the vehicle and the vehicle directly behind the vehicle is equal to the second distance threshold, the current input to the first electromagnet and the second electromagnet by the power module 3 is just increased to the maximum current that the first electromagnet and the second electromagnet can withstand, thereby assisting the braking to prevent the vehicle from colliding with the vehicle in front, and assisting the braking to prevent the vehicle behind from colliding with the vehicle. Thus, the repulsive force generated between the same magnetic poles of different electromagnets is used to assist the vehicle braking. Moreover, the above braking principle has nothing to do with temperature and oil. When the vehicle's brake pads are too hot or the brake lines are leaking oil, it can still provide braking force for the vehicle, thereby increasing the reliability and safety of the vehicle and effectively avoiding the occurrence of collision accidents.

[0047] When the vehicle is parked and in a ready state, and the brake pedal is in a braking state, the control module 2 controls the power module 3 to input the maximum current that the first electromagnet and the second electromagnet can withstand to the first electromagnet and the second electromagnet, which can assist the vehicle in braking better and greatly improve the safety of the vehicle during braking.

[0048] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
