The invention relates to a brake system including at least one brake with an electric brake actuator, at least one electronic control unit for controlling the at least one electric brake, and two different power supply units connected to the at least one electronic control unit and configured for supplying energy to the at least one electric brake actuator. The at least one electronic control unit comprises a first brake actuation system for activating the electric brake actuator and a redundant brake actuation system for activating the electric brake actuator in case of a failure of the first brake actuation system. The invention also relates to a method for using the brake system.

Brake system

A electric brake system includes a main device that provides a first hydraulic pressure to a plurality of wheel cylinders respectively installed on a plurality of wheels, based on a position of a brake pedal; and art auxiliary device that provides a second hydraulic pressure to first and second wheel cylinders respectively installed on first and second wheels among the plurality of wheels based on the position of the brake pedal in a state in which the main device does not generate the first hydraulic pressure. The auxiliary device receives power from a power network different from that of the main device, and the auxiliary device controls at least one of first and second parking brakes respectively installed on third and fourth wheels among the plurality of wheels. In such an electric brake system, when the main device fails or is out of control, the auxiliary device may auxiliary generate the hydraulic pressure required for braking and may generate braking force using the parking brake.

Electronic brake system and control method therefor

Brake system () for a vehicle is provided, comprising a first hydraulic circuit () including a first wheel brake (), a second hydraulic circuit () including a second wheel brake (), a first hydraulic pressure supplier () including an actuator for pressurizing the first hydraulic circuit () in a normal operating mode, a second hydraulic pressure supplier () including an actuator for pressurizing the second hydraulic circuit () in the normal operating mode, a cut-off valve () hydraulically connecting the first and second hydraulic circuits (), a first control unit () for controlling the cut-off valve () and activating the first hydraulic pressure supplier () and the second hydraulic pressure supplier () depending on a brake request, and a second control unit () for controlling the cut-off valve () and activating the first hydraulic pressure supplier () and the second hydraulic pressure supplier () depending on a brake request.

The invention relates to a floor mounted brake pedal for an electrically controlled vehicle brake, comprising a first pedal lever, a second pedal lever arranged in front of the first pedal lever, a pedal platform having a stepping area and a shaft protruding from the stepping area in a forward direction, a first pedal sensor for detecting a position of the brake pedal, and a second pedal sensor for independently detecting the position of the brake pedal.
