Description
Technical Field
The invention relates to an ABS (anti-lock brake system), in particular to an oil-gas composite ABS.
Background
At present, the main braking bodies of various domestic motor vehicles such as diesel vehicles, gasoline vehicles or dual fuels and the like are double-loop oil braking or double-loop air braking, and the two braking ABS anti-lock systems are ABS hydraulic braking or ABS air pressure braking. The front oil-rear-air composite brake system is provided with double brake energy sources, overcomes the defects of small brake force of the oil brake ABS, high manufacturing cost of the air brake ABS, complex structure and the like, and is a safe and reliable brake system. However, at present, ABS anti-lock braking cannot be realized for front oil-rear-gas composite braking of motor vehicles.
Disclosure of Invention
Aiming at the problems, the invention provides an oil-gas composite ABS anti-lock brake system which can solve the problem of safe braking of a vehicle and realize energy conservation, consumption reduction and environmental protection.
When the automobile is braked, if the wheels are locked and slide, the lateral adhesive force between the wheels and the road surface completely disappears. If only the front wheels (steered wheels) are braked to a locking slip and the rear wheels are rolling, the vehicle will lose steering capability. If only the rear wheel is braked to be locked and slipped and the front wheel is still rolling, even if a small lateral interference force is applied to the automobile, the automobile can generate a sideslip (tail flick) phenomenon. These are very likely to cause serious traffic accidents. Therefore, the vehicle is not required to brake the wheels to a locking slip at the time of braking, but is required to brake the wheels to a rolling-while-slipping state. The invention relates to an ABS anti-lock braking system which can be applied to diesel vehicles, gasoline vehicles, oil-gas dual-fuel vehicles and various special vehicle operation vehicles.
In order to solve the problems, the invention adopts the technical scheme that: the oil-gas composite ABS anti-lock brake system comprises a composite electric controller ECU, a hydraulic regulator and a pneumatic regulator, wherein the composite electric controller ECU comprises an operation unit, a control unit and a monitoring unit which are sequentially connected;
the two operation units are respectively used for acquiring front and rear wheel speed signals from the wheel speed sensors, performing operation analysis processing and analyzing whether wheels are about to be locked to drag and slide;
a control unit for controlling the action of the hydraulic regulator or the air pressure regulator according to the operation analysis results of the two operation units;
the monitoring unit is used for detecting and judging the working condition of the system and giving an alarm through the alarm when a fault influencing the normal work of the system is found;
one end of the hydraulic regulator is connected to a brake master cylinder connected with a liquid reservoir, and the other end of the hydraulic regulator is connected to a front wheel brake; the brake master cylinder is connected with one end of an air storage tank and one end of an air pressure regulator through a hydraulic control air valve, the air storage tank is connected with an air pump through a one-way valve, and the other end of the air pressure regulator is connected to a rear wheel brake; the brake master cylinder is connected with a brake pedal through a vacuum booster.
The ECU of the composite electric controller is simultaneously connected with a hydraulic electromagnetic valve control circuit and a pneumatic electromagnetic valve control circuit which can simultaneously control the action of a hydraulic pressure regulator or a pneumatic pressure regulator so as to control the increase and decrease of the air pressure or the hydraulic pressure.
Preferably, the wheel speed sensor is connected to the arithmetic unit through a signal line.
Preferably, the hydraulic modulator and the pneumatic modulator are connected to the front wheel brake and the rear wheel brake, respectively, through brake pipes.
Preferably, the wheel speed sensors include a left front wheel rotation speed sensor, a right front wheel rotation speed sensor, a left rear wheel rotation speed sensor and a right rear wheel rotation speed sensor; the front wheel brake comprises a left front wheel brake and a right front wheel brake; the rear wheel brake comprises a left rear wheel brake and a right rear wheel brake. This is the case for four sensors.
The braking principle of the oil-gas composite ABS anti-lock braking system is as follows: in the braking process, the composite electric controller ECU continuously obtains wheel speed signals from the left front wheel rotating speed sensor, the right front wheel rotating speed sensor, the left rear wheel rotating speed sensor and the right rear wheel rotating speed sensor, and the wheel speed signals are respectively transmitted to the arithmetic unit for analysis and processing, and whether a vehicle is about to be locked and dragged to slide or not is analyzed. If no wheel is about to be locked to drag and slip, the hydraulic pressure regulator and the air pressure regulator do not work. If the composite electric controller ECU analyzes and judges a certain front wheel, the left front wheel is supposed to be locked and dragged to slide, the control unit sends an instruction, namely sends a command to the hydraulic pressure regulator, and closes a channel between the brake master cylinder and the left front wheel brake, so that the pressure of the left front wheel brake is not increased any more, namely the pressure maintaining state in the braking process of the ABS system. If the composite electric controller ECU judges that the left front wheel still tends to be in a locked dragging and sliding state, the composite electric controller ECU sends an instruction to the control unit, namely, sends an instruction to the hydraulic regulator, and opens a channel between the left front wheel brake and the reservoir to reduce the oil pressure in the left front wheel brake, namely, the pressure reduction state in the braking process of the ABS system. If the ECU judges that the left rear wheel still tends to be in the locking dragging sliding state, the ECU sends an instruction to the control unit to send an instruction to the air pressure regulator to open the left rear wheel brake to communicate with the atmosphere to reduce the air pressure in the left rear wheel brake, namely the pressure reduction state in the braking process of the ABS system.
The ABS anti-lock double-loop integrating the vehicle front oil and rear gas composite braking is safe and reliable.
The ABS anti-lock system of the front oil and rear gas composite brake has a self-diagnosis function, can detect and judge the working condition of the system, automatically turns off the ABS and lights up the warning lamp to send a warning signal to a driver once a fault influencing the normal work of the system is found, the brake system of the vehicle brakes like a conventional brake system, and the vehicle does not have the anti-lock function and please pay attention to safety.
Preferably, the wheel speed sensors comprise a left front wheel speed sensor, a right front wheel speed sensor and a rear wheel speed sensor arranged in a differential of a rear axle; the front wheel brake comprises a left front wheel brake and a right front wheel brake; the rear wheel brake comprises a left rear wheel brake and a right rear wheel brake. This is the case with three sensors, i.e. only one rear wheel speed sensor behind. Preferably, the left front wheel brake and the right front wheel brake are respectively connected to the brake master cylinder through a hydraulic regulator or the left front wheel brake and the right front wheel brake are respectively connected to the brake master cylinder through the same hydraulic regulator; the left rear wheel brake and the right rear wheel brake are respectively connected to the brake master cylinder through one air pressure regulator or the left rear wheel brake and the right rear wheel brake are connected to the brake master cylinder through the same air pressure regulator. The ABS system is divided into four-sensor four-channel ABS system, four-sensor three-channel ABS system (front 1 and rear 2 and front 2 and rear 1), four-sensor two-channel ABS system, three-sensor four-channel ABS system, three-sensor three-channel ABS system (front 1 and rear 2 and front 2 and rear 1), and three-sensor two-channel ABS system.
Compared with the existing double-loop oil braking or double-loop air braking, the oil-gas composite ABS anti-lock braking system has the advantages that the double loops of the system are used for an engine to provide double braking energy: the oil-gas composite ABS anti-lock brake system is safe and reliable, and is characterized in that an oil path and an oil path are failed, a double-brake safety is safer, the advantages of simple structure and large braking force of the oil brake ABS are absorbed, and the defects of small braking force, large and complex manufacturing cost and the like of the oil brake ABS are overcome.
