Braking system for vehicles with collapsible actuation pedal and method of actuation of a braking system in the event of an impact

A braking system for vehicles with a collapsible actuation pedal, comprising:

• an operating pedal operatively connected to a hydraulic pump having a delivery circuit fluidically connected to an accumulator device, wherein
• the delivery circuit comprises a hydraulic branch equipped with at least one normally closed control valve,
• said control valve being connected to a control actuator which commands its opening when an impact or accident is detected by a special detector or being calibrated to open automatically when a limit pressure and/or flow rate value is reached in the hydraulic branch following the lowering of the actuation pedal.

An actuation method of a braking system in case of impact, comprising:

• providing a braking system for vehicles with collapsible actuation pedal, comprising an actuation pedal operatively connected to a hydraulic pump having a delivery circuit fluidically connected to an accumulator device,
• depressurising the delivery circuit in the event of detection of an impact of the vehicle on which said braking system is installed and/or in the event of exceeding a pressure and/or flow rate limit value in said delivery circuit.
