Problems solved by technology
[0002] Existing cars generally use hydraulic brakes, and the driver operates the brake shoe to press the brake drum through the hydraulic pressure to achieve braking. Excessive pressure on the brake shoe will cause the wheel to slip and lock the wheel, resulting in unstable braking and braking. Serious consequences such as reduced dynamic performance and sideslip; when the car starts quickly, the wheels are prone to slip, resulting in reduced traction and vehicle deviation; the existing braking device has severe steering wheel vibration, severe brake pedal rebound, and valve core Stuck and lost braking force and other problems, and its structure is complex, high price, insensitive action, poor safety

The invention relates to a vehicle brake device which is intelligently controlled. It is formed by a hydraulic device and a controller. Wherein, said hydraulic device comprises a hydraulic pump, a liquid storage device with a liquid level switch, an energy storage device with a pressure signal sender, an electromagnetic valve with a micro-motion switch, and a brake main cylinder; the main control circuit board is connected to the external storage battery DC. It is characterized in that: the hydraulic device is arranged with a safety vale, a range valve, a pressure variable valve, a pressure switch and a electromagnetic valve; the main control circuit board is formed by parallel control unit, output unit, and alarm unit, while the control unit is formed by a current rectifier, a resistance, a capacitor, a diode, a transistor, a acceleration sensor, a comparer, and a optical coupler. The invention uses the control unit to detect the slide rate of wheel, to send out the instructions of increasing or decreasing pressure to drive the hydraulic device, therefore, it can effectively solve the problems that slide, locking and instable brake.
Description
1. Technical field [0001] The invention discloses an automobile brake device, in particular to an intelligently controlled automobile brake device, which belongs to the technical field of automobile brake control. 2. Background technology [0002] Existing cars generally use hydraulic brakes, and the driver operates the brake shoe to press the brake drum through the hydraulic pressure to achieve braking. Excessive pressure on the brake shoe will cause the wheel to slip and lock the wheel, resulting in unstable braking and braking. Serious consequences such as reduced dynamic performance and sideslip; when the car starts quickly, the wheels are prone to slip, resulting in reduced traction and vehicle deviation; the existing braking device has severe steering wheel vibration, severe brake pedal rebound, and valve core Jamming and loss of braking force and other problems, and its complex structure, high price, insensitive action, poor safety. 3.
