METHOD FOR HYDRAULIC BRAKE ACTUATOR CONTROL TO PROVIDE AUTOMATIC VEHICLE BRAKING Russian patent published in 2014 - IPC B60T8/32 B60T8/66 B60T8/86 B60T7/12 

FIELD: transport.

SUBSTANCE: method consists in control and recording during motion a number of measured and calculated motion parameters which serve for preliminary setting criteria of automatic braking process start and end. When this mode occurs braking fluid in main brake cylinder and braking gear control circuits of front and rear wheels are used while maintaining functionality of antilock system. During braking vehicle clutch control is additionally performed using independent single-circuit hydraulic unit. Target deceleration is implemented by means of setting time of electric motors operation and powering accumulator solenoid valves (separately for hydraulic units of braking gear control and of clutch control). The initial point is calculation of pressures required in each circuit of used hydraulic units, and during braking shutoff and accumulator solenoid valves are controlled in corresponding hydraulic circuits.

EFFECT: possibility to perform braking with various intensity in automatic mode due to creation of different pressures in braking system circuits and in clutch hydraulic drive circuit of vehicles.
