Abstract
A braking device for a vehicle having an operational hydraulic brake system, and an electronically controlled brake system. The hydraulic brake system and the electronically controlled brake system act independently on a brake caliper of a hydraulic brake. The electronically controlled brake system independently controls the hydraulic actuator for applying a hydraulic pressure to the brake caliper with no interference between the brake systems, which increases the degree of freedom of electronic control of the brakes. A braking device is also applied in a vehicle having an ABS control device.
Claims10
A braking device for a vehicle comprising:
- a hydraulic brake having a brake caliper with a plurality of ports;
- an operational brake system for supplying a braking pressure input to a first port of said brake caliper;
- a pressure sensor for detecting the pressure in said operational brake system and for outputting a detection signal indicative of the operating pressure of said operational brake system;
- and
- an electronically controlled brake system having an actuator and an electronic control unit, the electronic control unit controlling the actuator in response to said detection signal from said pressure sensor supplied by the operational brake system for supplying a braking pressure input to a second port of said brake caliper;
- said operational braking system being arranged in parallel to said electronically controlled brake system wherein the braking pressure input supplied to said first port of said brake caliper is supplied in parallel to the braking pressure input to said second port of said brake caliper.
A braking device comprising:
- an operational brake system supplying a braking pressure input to a first port of a brake;
- a pressure sensor for detecting the pressure in said operational brake system and for outputting a detection signal indicative of the operating pressure of said operational brake system;
- and
- an electronically controlled brake system connected to a second port of said brake, said detection signal from said pressure sensor being supplied to said electronically controlled brake system for providing a braking pressure input to said second port of said brake;
- wherein
- the operational brake system and the electronically controlled brake system apply respective braking pressures to respective ports without interference between the respective braking pressures.
