The anti-lock braking system is the core of the two-wheel vehicle braking technology, and has the function of automatically controlling the braking force of the brake when the two-wheel vehicle brakes, so that wheels are not locked and are always in a rolling and sliding state, the two-wheel vehicle is prevented from drifting, the adhesion force between the wheels and the ground is always kept to be the maximum in the braking process, the minimum braking distance is ensured, the braking stability of the vehicle can be ensured, and the driving safety is improved. Although the anti-lock braking system of the two-wheel vehicle is developed relatively well in China, most of the anti-lock braking system consists of a valve block, a pressure increasing and decreasing valve, an eccentric motor, an energy accumulator and an electronic control unit, the system can only keep the maximum deceleration and the vehicle stability when the vehicle is braked in an emergency situation in the straight line driving process through the opening or closing state of an electromagnetic valve in a mechanical control valve block, and when the vehicle is braked in an emergency situation on complex road conditions such as a curve and the like, the vehicle is easy to overturn due to instability of the vehicle caused by improper control.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects of the prior art and provides a two-wheel vehicle anti-lock braking system which can monitor the pressure of a main cylinder in real time, adjust the linear control of an electromagnetic valve and improve the safety and reliability under complex road conditions.
The technical scheme of the invention is to provide a two-wheel vehicle brake anti-lock system with the following structure: the brake system comprises a hydraulic driving unit, an electronic control unit, at least one brake master cylinder and at least one brake wheel cylinder; the hydraulic driving unit comprises a valve body, an eccentric motor and at least one energy accumulator, wherein a main cylinder oil port communicated with a brake main cylinder and a wheel cylinder oil port communicated with the brake wheel cylinder are arranged on the valve body, at least one control channel is arranged in the valve body, each control channel comprises a first electromagnetic valve, a second electromagnetic valve, a pump oil inlet one-way valve, a plunger pump and a pump oil outlet one-way valve which are arranged in the valve body, and the main cylinder oil port, the first electromagnetic valve, the wheel cylinder oil port, the second electromagnetic valve, the energy accumulator, the pump oil inlet one-way valve, the plunger pump, the pump oil outlet one-way valve and the main cylinder oil port are sequentially communicated to form the control; the eccentric motor is used for driving the plunger pump to act; the electronic control unit is electrically connected with the eccentric motor, the first electromagnetic valve and the second electromagnetic valve and is used for controlling the eccentric motor, the first electromagnetic valve and the second electromagnetic valve to act; a first flow passage is formed between the main cylinder oil port and the first electromagnetic valve, a pressure sensor is connected to the first flow passage, and the pressure sensor is electrically connected with the electronic control unit and used for detecting the pressure of the main cylinder in the braking process and transmitting the detected signal to the electronic control unit.
After adopting the structure, compared with the prior art, the anti-lock braking system for the two-wheel vehicle has the following advantages:
when the vehicle runs on a complex road surface such as a road surface with sand, gravel and asphalt and rainwater staggered, if the opening and closing states of the first electromagnetic valve and the second electromagnetic valve in the system are controlled by the electronic control unit, the working pressure of the brake wheel cylinder is difficult to be accurately controlled, so that the stability and the optimal deceleration state of the vehicle cannot be ensured. At this time, the dynamic control characteristics of the first electromagnetic valve and the second electromagnetic valve need to be changed, and the characteristics can be reflected by the pressure fluctuation of the brake master cylinder, so that the pressure sensor is arranged on the first flow channel, the pressure of the brake master cylinder in the braking process can be monitored in real time, the detected signals are transmitted to the electronic control unit, and the electronic control unit controls the working pressure of the wheel cylinder more accurately by using a control mode of Pulse Width Modulation (PWM) or Pulse Frequency Modulation (PFM) through pressure estimation, thereby improving the braking comfort of a driver and the safety and reliability when the driver drives on a complex road condition.
As an improvement, the electronic control unit is connected with an inclination angle sensor, and the inclination angle sensor is used for detecting the inclination angle of the vehicle in the running process and transmitting the detected signal to the electronic control unit. When the vehicle runs on a curve and is braked suddenly, the contact surface between the tire of the vehicle and the ground is small, if the vehicle runs on a straight line according to control logic, a wheel speed sensor collects a wheel speed signal and transmits the signal to an electronic control unit, the electronic control unit analyzes the signal to estimate the vehicle speed and deceleration at the moment, the slip ratio of the wheel is calculated by comparing the slip ratio with the wheel speed, the adhesion coefficient and the change of the adhesion coefficient of the ground are estimated, then an instruction is sent to a hydraulic driving unit, the hydraulic driving unit acts according to the instruction of the electronic control unit, and the unstable braking can be caused by the fact that the estimation of the vehicle speed and the adhesion coefficient has larger difference with the actual value at the moment. The invention adds the tilt angle sensor in the electronic control unit, the tilt angle sensor is used for collecting the vehicle tilt angle signal and transmitting the collected signal to the electronic control unit, the transverse speed and the longitudinal speed of the vehicle during braking and the real-time adhesion coefficient of the tire and the ground can be accurately calculated through the internal algorithm of the electronic control unit, thereby more accurately controlling the working pressure distribution of the front brake and the rear brake, achieving the effect that the anti-lock and steering capacity of the vehicle on a curve is still, ensuring that the vehicle braking is safer and more effective, the braking distance is shorter and the service life of the tire is longer.
Preferably, a second flow passage is formed among the first electromagnetic valve, the wheel cylinder oil port and the second electromagnetic valve; a third flow passage is formed between the second electromagnetic valve and the energy accumulator and between the second electromagnetic valve and the pump oil inlet one-way valve; and a fourth flow passage is formed among the pump oil inlet one-way valve, the plunger pump and the pump oil outlet one-way valve, and the fourth flow passage forms a high-pressure cavity because the eccentric motor drives the plunger pump to work.
Preferably, the first electromagnetic valve is a normally open electromagnetic valve, and the second electromagnetic valve is a normally closed electromagnetic valve. Under the condition of the vehicle in normal driving, the electronic control unit controls the first electromagnetic valve to be not electrified so as to enable the first electromagnetic valve to be in a normally open state, and the electronic control unit controls the second electromagnetic valve to be not electrified so as to enable the second electromagnetic valve to be in a normally closed state.
Preferably, the number of the master cylinders and the number of the wheel cylinders are two, and the number of the control channels is two. The brake master cylinder generally comprises a front wheel brake master cylinder and a rear wheel brake master cylinder, wherein the brake wheel cylinders, namely a front wheel brake wheel cylinder and a rear wheel brake wheel cylinder, are connected with a front wheel brake caliper, and the rear wheel brake wheel cylinder is connected with a rear wheel brake caliper; the control channel is two, namely a double-channel anti-lock braking system. After setting up like this, when meetting emergency driver and pinching the front brake, if pressure sensor detects the front wheel master cylinder pressure too big, can transmit the signal that detects to the electronic control unit, the electronic control unit can control the pressure of vehicle rear wheel jar, makes the rear wheel also have certain deceleration, avoids leading to the vehicle to stick up the tail because of the difference in front and rear wheel speed is too big, then causes the casualty accident.

As shown in fig. 1, 2, 3 and 4; the invention discloses a two-wheel vehicle anti-lock braking system with the following structure: the brake system comprises a hydraulic drive unit 1, an electronic control unit 2, at least one brake master cylinder 3 and at least one brake wheel cylinder 4; the hydraulic driving unit 1 comprises a valve body, an eccentric motor 5 and at least one energy accumulator 6, a main cylinder oil port 7 communicated with a brake main cylinder 3 and a wheel cylinder oil port 8 communicated with a brake wheel cylinder 4 are arranged on the valve body, at least one control channel is arranged in the valve body, each control channel comprises a first electromagnetic valve 9, a second electromagnetic valve 10, a pump oil inlet one-way valve 11, a plunger pump 12 and a pump oil outlet one-way valve 13 which are arranged in the valve body, and the main cylinder oil port 7, the first electromagnetic valve 9, the wheel cylinder oil port 8, the second electromagnetic valve 10, the energy accumulator 6, the pump oil inlet one-way valve 11, the plunger pump 12, the pump oil outlet one-way valve 13 and the main cylinder oil port 7.

A second flow passage 17 is formed between the first electromagnetic valve 9 and the wheel cylinder oil port 8 and between the first electromagnetic valve and the second electromagnetic valve 10; a third flow channel 18 is formed between the second electromagnetic valve 10 and the energy accumulator 6 and between the second electromagnetic valve and the pump oil inlet one-way valve 11; a fourth flow passage 19 is formed between the pump oil inlet check valve 11 and the plunger pump 12 and the pump oil outlet check valve 13, and the fourth flow passage 19 forms a high-pressure cavity because the eccentric motor 5 drives the plunger pump 12 to work.
The number of the brake master cylinder 3 and the number of the brake wheel cylinders 4 are two, and the number of the control channels is also two. The brake master cylinder 3 generally comprises a front wheel brake master cylinder 3 and a rear wheel brake master cylinder 3, the brake wheel cylinders 4 are also a front wheel brake wheel cylinder 4 and a rear wheel brake wheel cylinder 4, the front wheel brake wheel cylinder 4 is connected with a front wheel brake caliper, and the rear wheel brake wheel cylinder 4 is connected with a rear wheel brake caliper; the control channel is two, namely a double-channel brake anti-lock system.
The first solenoid valve 9 is a normally open solenoid valve, and the second solenoid valve 10 is a normally closed solenoid valve. Under the condition that the vehicle is in normal driving, the electronic control unit 2 controls the first electromagnetic valve 9 not to be electrified, so that the first electromagnetic valve 9 is in a normally open state, and the electronic control unit 2 controls the second electromagnetic valve 10 not to be electrified, so that the second electromagnetic valve 10 is in a normally closed state.
When the vehicle runs on a complex road surface such as a road surface with sand, asphalt and rainwater staggered, if the electronic control unit 2 is used to control the open and close states of the first electromagnetic valve 9 and the second electromagnetic valve 10 in the system, it is difficult to accurately control the working pressure of the brake wheel cylinder 4, so that the stability and the state of optimal deceleration of the vehicle cannot be ensured. At this time, the dynamic control characteristics of the first electromagnetic valve 9 and the second electromagnetic valve 10 need to be changed, and the characteristics can be reflected by the pressure fluctuation of the master cylinder 3, so that the pressure sensor 15 is arranged on the first flow passage 14, the pressure of the master cylinder 3 in the braking process can be monitored in real time, the detected signals are transmitted to the electronic control unit 2, and the electronic control unit 2 can more accurately control the working pressure of the wheel cylinder by using a control mode of Pulse Width Modulation (PWM) or Pulse Frequency Modulation (PFM) through pressure estimation, thereby improving the braking comfort of a driver and the safety and reliability when the driver drives on a complex road condition.
The Pulse Width Modulation (PWM) control method is to change the duty ratio of each periodic signal under a fixed control period to control the switching rate and the opening degree of each valve, wherein under the same periodic signal, the larger the duty ratio is, the faster the closing response time or the smaller the opening degree of the valve is for the first solenoid valve 9, and the faster the opening response time or the larger the opening degree is for the second solenoid valve 10, and vice versa. The Pulse Frequency Modulation (PFM) control method is to control the switching rate and the opening degree of each solenoid valve by changing the period of a control signal under the premise that the duty ratio is not changed, and under the condition of the same duty ratio, the longer the control period is, the more the pressure is increased when the first solenoid valve 9 is opened each time, and the more the pressure is reduced when the second solenoid valve 10 is opened. The two solenoid valves can be linearly controlled by the two control methods, and in order to obtain good control quality, the parameters in the electronic control unit 2 are adjusted to obtain a proper control period and duty ratio by comprehensively considering the state of the vehicle and the system structure. The pressure increasing, pressure maintaining and pressure reducing processes in the braking process can also be realized by adjusting the opening size of the electromagnetic valve, so that the control frequency of the electromagnetic valve is reduced, the electromagnetic valve can be used for a longer time, and the durability of the system is improved.
In addition, when a driver in an emergency state pinches a front brake, if the pressure sensor 15 detects that the pressure of the front wheel main cylinder is too high, the detected signal is transmitted to the electronic control unit 2, and the electronic control unit 2 can control the pressure of a rear wheel cylinder of the vehicle, so that the rear wheel has certain deceleration, and the problem that the tail of the vehicle is warped due to the fact that the speed difference between the front wheel and the rear wheel is too high, and casualty accidents are caused is avoided.
An inclination sensor 16 is connected to the electronic control unit 2, and the inclination sensor 16 is used for detecting an inclination angle of the vehicle during driving and transmitting a detected signal to the electronic control unit 2. When the vehicle runs on a curve and is braked suddenly, the contact surface between the tire of the vehicle and the ground is small, if the vehicle runs on a straight line according to control logic, a wheel speed sensor collects a wheel speed signal and transmits the signal to the electronic control unit 2, the electronic control unit 2 analyzes the signal to estimate the vehicle speed and the deceleration at the moment, the slip ratio of the wheel is calculated by comparing the slip ratio with the wheel speed, the adhesion coefficient and the change of the adhesion coefficient of the ground are estimated, then an instruction is sent to the hydraulic driving unit 1, the hydraulic driving unit 1 acts according to the instruction of the electronic control unit 2, and the unstable braking can be caused by the fact that the difference between the estimation of the vehicle speed and the adhesion coefficient and the actual situation is large. The invention adds the tilt angle sensor 16 in the electronic control unit 2, the tilt angle sensor 16 is used for collecting the vehicle tilt angle signal and transmitting the collected signal to the electronic control unit 2, the transverse speed and the longitudinal speed of the vehicle during braking and the real-time adhesion coefficient of the tire and the ground can be accurately calculated through the internal algorithm of the electronic control unit 2, thereby more accurately controlling the working pressure distribution of the front brake and the rear brake, achieving the effect that the anti-lock and steering capacity of the vehicle on a curve is still, ensuring that the vehicle braking is safer and more effective, the braking distance is shorter, and the service life of the tire is longer.
