Description

Technical Field

[0001] The present invention relates to the technical field of automobile brakes, and in particular to an automobile brake based on multi-sensor monitoring. Background Art

[0002] With the rapid development of the automotive industry, vehicle safety has become a key concern. As a key component for ensuring safe driving, the stability and reliability of vehicle brake performance are crucial. Traditional vehicle brakes rely primarily on driver input, lacking effective monitoring and precise control of the vehicle's real-time motion.

[0003] Most existing automotive braking systems lack sensor monitoring devices, making them unable to collect real-time data on the vehicle's motion state. Lacking this sensor data, the braking system struggles to fully and accurately perceive the vehicle's driving conditions, relying solely on the driver's experience and judgment to apply the brakes. In complex driving conditions, such as high speeds, emergency turns, or poor road conditions, traditional braking systems are unable to automatically adjust braking force based on the vehicle's actual motion. This can easily lead to untimely braking and irrational braking force distribution, increasing the risk of skidding, tailspinning, and even loss of control, seriously impacting vehicle safety.

[0004] In addition, in terms of braking intervention, traditional automobile brakes mainly apply braking force by the driver stepping on the brake pedal, and lack an automatic control mechanism.

[0005] Especially when the vehicle is in different emergency situations, it is impossible to automatically initiate corresponding braking intervention measures based on the real-time monitored vehicle motion status data, and it is difficult to provide appropriate braking force at the best time, thereby limiting the performance of the braking system and failing to meet the high safety and intelligence requirements of modern cars.

[0009] Preferably, the information acquisition module includes: a steering angle and vehicle speed integrated sensor and an acceleration and wheel speed integrated sensor; The steering angle and vehicle speed integrated sensor is used to collect the vehicle's wheel speed n and steering wheel angle θ; The acceleration wheel speed integrated sensor is used to collect vehicle speed v and vehicle acceleration a; The wheel speed n, steering wheel angle θ, vehicle speed v and vehicle acceleration a collected by the steering angle and speed integrated sensor and the acceleration wheel speed integrated sensor are sent to the information processing module through the built-in data transceiver.

[0010] Preferably, the information processing module is used to filter and denoise the vehicle motion state data collected by the information acquisition module. The information processing module extracts effective feature information data from the preprocessed data, fuses the extracted feature information data, and transmits the fused data to the vehicle driving system through the CAN communication circuit. The information processing module is used to convert the vehicle motion state data into effective feature information data.

[0011] Preferably, the filtering and denoising preprocessing in the information processing module uses hardware RC filtering and software multi-stage filtering; Among them, the effective features are extracted: The vehicle speed v and the vehicle acceleration a are filtered using a sliding window mean filter to obtain the vehicle speed v and the vehicle acceleration a after the sliding window mean filter; The wheel speed n and steering wheel angle θ are filtered by Kalman filtering to obtain the state estimation value after Kalman filtering.

This structural design is reasonable and easy to install, which can ensure that each module works stably during vehicle driving, thereby improving the reliability and durability of the entire braking system.

[0016] By incorporating an information acquisition module, including an integrated steering angle and vehicle speed sensor and an integrated acceleration and wheel speed sensor, key motion state data such as the vehicle's wheel speed n, steering wheel angle θ, vehicle speed v, and vehicle acceleration a can be accurately collected in real time. The collaborative operation of these multiple sensors provides the braking system with comprehensive and rich vehicle operating information, enabling the braking system to perceive the vehicle's driving state in real time and providing a reliable data foundation for subsequent braking interventions. Compared to traditional braking systems lacking sensor support, this invention can more accurately capture the vehicle's motion state, avoiding braking decision errors caused by missing information.

[0017] Based on preset thresholds for valid characteristic information data, the vehicle's driving system automatically determines the vehicle's driving condition and generates corresponding control signals to control the brake intervention unit.

[0020] Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0021] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0022] In addition, numerous specific details are provided in the following detailed description to better illustrate the present disclosure. Those skilled in the art will appreciate that the present disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art are not described in detail in order to highlight the main points of the present disclosure.

[0023] Reference Figures 1-6 As shown, an automobile brake based on multi-sensor monitoring in this embodiment includes a brake caliper 1, a brake disc 2, an information processing module 3, a steering knuckle bracket 4, an information acquisition module 7 and a brake intervention unit 103.

[0024] The brake caliper 1 is fixedly mounted on the brake disc 2. A steering knuckle bracket 4 is mounted on the top of the brake disc 2. Both ends of the steering knuckle bracket 4 are provided with through-holes. Circular through-hole 101 and circular through-hole 2 102 are respectively provided on the ends of the caliper body bracket of the brake caliper 1. Bolts 1 401 and 2 402 are respectively fixedly mounted between the through-holes in the steering knuckle bracket 4 and the circular through-holes in the caliper body bracket. The bolts secure the brake caliper 1 and steering knuckle bracket 4 to the brake disc 2. The information processing module 3 passes through the threaded hole in the center of the steering knuckle bracket 4 and the through-hole 3 203 in the center of the brake disc 2, then is rotatably fixed to the center of the steering knuckle bracket 4. An information acquisition module 7 is fixedly mounted on the side of the steering knuckle bracket 4.

[0025] Braking intervention unit 103, mounted on the outer wall of the hydraulic cylinder at the top of brake caliper 1, includes a hydraulic piston mechanism that automatically adjusts the braking force to clamp brake disc 2 in various emergency situations. Steering angle and vehicle speed integrated sensor 5 in information acquisition module 7 collects the vehicle's wheel speed n and steering wheel angle θ, while acceleration and wheel speed integrated sensor 6 collects vehicle speed v and acceleration a. These data are transmitted to information processing module 3 via a built-in data transceiver.

[0026] Information processing module 3 filters and pre-processes the collected vehicle motion state data, extracting valid feature information data, including vehicle speed v, vehicle acceleration a, wheel speed n, and steering wheel angle θ. After integration, the data is transmitted to the vehicle driving system via the CAN communication circuit. The vehicle driving system generates corresponding control signals based on preset valid feature information thresholds, controlling the brake intervention unit 103 to activate different braking forces, as follows: When v>60km / h, |a|>3m / s², 10°<|θ|<15° and wheel speed difference Δn>10%, the warning brake is activated, 10% of the basic braking force is applied, and hydraulic brake intervention is used; When v>75km / h, |a|>3m / s², 15°<|θ|<30° and wheel speed difference Δn>15%, active braking is initiated, linearly increasing to 60% braking force, and hydraulic brake intervention is used; When v>95km / h, |a|>3m / s², |θ|>30° and wheel speed difference Δn>20%, emergency braking is initiated with full pressure output and hydraulic brake intervention.

[0027] In some examples, the brake intervention unit 103 controls the magnitude of the braking force by automatically adjusting the amount of brake fluid supplied to the brake caliper 1 .

[0028] In some examples, the bottom of the brake disc 2 is provided with a base 201, which is provided with multiple threaded through-holes. Multiple bolts 202 pass through the threaded through-holes to secure the brake disc 2 to the vehicle. This arrangement provides a more stable connection between the brake disc 2 and the vehicle, capable of withstanding various forces and vibrations generated during vehicle operation. This ensures the stability of the brake disc 2 during long-term use, prevents the braking effect from being affected by loose connections, and improves the reliability of the entire braking system.

[0029] In some examples, the filtering and denoising preprocessing in information processing module 3 utilizes hardware RC filtering and software multi-stage filtering. Specifically, the vehicle speed v and acceleration a are filtered using a sliding window mean filter to obtain the vehicle speed v and acceleration a after sliding window mean filtering. The wheel speed n and steering wheel angle θ are filtered using a Kalman filter to obtain a Kalman filtered state estimate. This combined hardware and software filtering approach effectively removes noise and interference from sensor data, improving data accuracy and reliability. This provides more precise data support for subsequent braking decisions, enabling the braking system to more accurately determine the vehicle's driving state and make appropriate braking interventions.

[0030] In some examples, the vehicle driving system includes an information receiving module, an information judgment module, a brake signal generation module, and an alarm module. The information receiving module is used to receive valid characteristic information data sent from the CAN communication circuit; the information judgment module is used to determine within which preset threshold range the received data falls and send the preset threshold of the range to the brake signal generation module; the brake signal generation module is used to receive the preset threshold and generate a brake signal to transmit to the hydraulic piston mechanism; the alarm module receives the alarm signal generated by the brake signal generation module and issues an alarm. When the information judgment module reaches a certain preset threshold, the brake signal generation module is triggered to generate an alarm signal. This modular design provides a clear functional division of labor for the vehicle driving system, enabling efficient information processing and control signal generation. At the same time, the alarm module can issue a warning to the driver during braking intervention, reminding the driver to pay attention to the vehicle's driving status, further improving driving safety.

[0031] In some examples, the information acquisition module 7 utilizes a combination of a steering angle and vehicle speed integrated sensor 5 and an acceleration and wheel speed integrated sensor 6. The steering angle and vehicle speed integrated sensor 5 can simultaneously collect wheel speed n and steering wheel angle θ, while the acceleration and wheel speed integrated sensor 6 can simultaneously collect vehicle speed v and vehicle acceleration a. Both integrated sensors transmit the collected data to the information processing module 3 via a built-in data transceiver. This multi-sensor integration design reduces the number of sensors and installation space, lowering system complexity and cost. It also enables real-time and accurate collection of key vehicle motion status data, enabling multi-sensor collaboration and providing the braking system with comprehensive and rich vehicle operating information, enabling the braking system to make more timely and accurate braking decisions.

[0032] In some examples, circular through-hole 101 and circular through-hole 2 102 provided on the caliper body bracket of the brake caliper 1 are fixedly connected to through-holes on the steering knuckle bracket 4 via bolt 1 401 and bolt 2 402. This connection method has a simple structure and is easy to install, ensuring a secure connection between the brake caliper 1 and the steering knuckle bracket 4. During vehicle operation, it can withstand the significant friction and impact forces generated during braking, ensuring stable operation of the brake caliper 1, enabling the brake intervention unit 103 to accurately apply braking force, and improving the reliability and durability of the brake system.

[0033] Working principle of the present invention: When using this multi-sensor monitoring system for automotive brakes, the system integration and data collection preparations are first completed by relying on the various modular structures. The brake caliper 1 is secured to the brake disc 2 via bolts 1 401 and 2 402, along with the steering knuckle bracket 4. The information processing module 3 is fixed through the center of the two. The information collection module 7, which includes a steering angle and vehicle speed integrated sensor 5 and an acceleration and wheel speed integrated sensor 6, is mounted on the side of the steering knuckle bracket 4 to ensure stable operation of all components while the vehicle is in motion.

[0034] After the vehicle starts, information acquisition module 7 acquires key motion data in real time: the steering angle and vehicle speed integrated sensor 5 collects wheel speed n and steering wheel angle θ, while the acceleration and wheel speed integrated sensor 6 collects driving speed v and acceleration a. This data is transmitted to information processing module 3 via a built-in transceiver. At this stage, the integrated sensor design reduces installation space and system complexity.

[0035] Information processing module 3 performs hierarchical filtering on the raw data: hardware RC filtering initially removes high-frequency noise, and then software multi-stage filtering further optimizes the data. Sliding window mean filtering smooths short-term fluctuations in v and a, while Kalman filtering dynamically estimates the states of n and θ. This generates valid feature data v, a, n, and θ, which are then transmitted to the vehicle's driving system via the CAN communication circuit. This combined hardware and software filtering strategy ensures data reliability under complex operating conditions.

[0036] After the information receiving module of the vehicle driving system obtains the characteristic data, the information judgment module determines the preset threshold range of the received valid characteristic information data according to the preset threshold interval, and sends the preset threshold range to the braking signal generation module.

[0037] Preset thresholds include: warning, active, and emergency braking; When v>60km / h, |a|>3m / s², 10°<|θ|<15° and wheel speed difference Δn>10%, the warning brake is triggered; If v>75km / h, |a|>3m / s², 15°<|θ|<30° and Δn>15%, active braking is initiated; Emergency braking is initiated when v > 95 km / h, |a| > 3 m / s², |θ| > 30°, and Δn > 20%. Different thresholds correspond to the brake signal generation module outputting differentiated control commands, driving the hydraulic piston mechanism on brake caliper 1 to adjust braking force: Precautionary braking applies a 10% base braking force, active braking increases linearly to 60%, and emergency braking applies full pressure, all of which achieve precise deceleration through hydraulic brake intervention.

[0038] During braking intervention, if the alarm trigger condition is met and emergency braking is initiated, the brake signal generation module simultaneously sends a signal to the alarm module, alerting the driver to the vehicle status through sound and lighting. The entire system requires no direct driver intervention. Through multi-sensor collaboration and threshold logic judgment, it automatically adjusts braking force to effectively handle complex conditions such as high-speed steering and wheel slip, improving braking safety and stability.

[0039] When system maintenance is required, the sensor's modular design offers significant advantages: the brake caliper 1, information processing module 3, and other components can be easily disassembled. The base 201, secured to the vehicle via bolts 202, ensures the stability of the brake disc 2, facilitating comprehensive inspection. The integrated layout of the sensor and processing module reduces maintenance requirements. Combined with the standardized design of hardware filtering circuits and software algorithms, this reduces subsequent debugging and troubleshooting costs, accommodating the vehicle's long-term, high-intensity operation.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
