Method for operating a brake system, brake systems in which the method is carried out and motor vehicles comprising said brakes systems

摘要

A method for the operation of a brake system having two brake circuits, with a recuperative brake, in particular an electrical generator, a master brake cylinder and a brake pedal simultaneously achieve optimized use of the regenerative braking and a constant braking experience for the driver with the highest safety requirements. When there is a braking demand by the driver with an associated desired braking torque and a first condition is met, at least one outlet valve is opened and brake fluid is conducted with an associated volume of brake fluid into at least one reservoir and the at least one outlet valve is then closed if a second condition is met. The first condition is met if a braking variable corresponding to the braking demand is not less than a specified minimum value. The second condition is met if the volume of brake fluid has flowed into the reservoirs.

1. A method for operating a brake system having two brake circuits, with a recuperative brake comprising an electrical generator, a master brake cylinder and a brake pedal, the method comprising:
opening at least one outlet valve so that brake fluid is conducted into at least one reservoir with an associated volume of brake fluid in an event of a driver's braking demand with an associated desired braking torque and if a first condition is met, and closing the at least one outlet valve if a second condition is met, wherein the first condition is met if a braking variable corresponding to the braking demand is not less than a specified minimum value, and if an available generator braking torque (Tq_rcap_0) available from the generator is greater than a specified minimum generator braking torque (Tq_min), wherein the second condition is met if the volume of brake fluid has flowed into the reservoirs.
