  • Publication number: 20240067146
    Abstract: A brake system (1) for braking a vehicle is disclosed. The brake system comprises a brake pedal control unit (4a1) configured to receive a brake pedal signal from a brake pedal sensor (21) and to respond with a primary deceleration intent signal onto a network, a brake actuator control unit (4b1) configured to activate a brake actuator (31) in response to a deceleration intent signal received from the network. The brake system (1) further comprises a central vehicle control unit (VCU) (6) that is configured to generate a secondary deceleration intent signal in response to the primary deceleration intent signal based on an overall state of the vehicle and a mode control unit (MCU) (8) to configure the brake system in an operational mode selected from at least a normal operational mode (N) and a degraded operational mode (D).

  • Publication number: 20230136605
    Abstract: A brake control unit (50) is provided comprising a primary control branch (510), a backup control branch (520), and mode control utilities (530), wherein the mode control utilities (530) are configured to select in accordance with integrity diagnostic indications an operational mode of the brake control unit from a plurality of potential operational modes comprising at least a normal operational mode and a degraded operational mode, wherein respectively the primary control branch (510) and the backup control branch (520) are configured to generate a brake motor drive signal (D10, D20) with their respective inverter being controlled by their respective control module in response to an external brake control signal (IB), wherein the primary control module (511) is configured to provide the integrity diagnostic indications in that it includes at least a first and a second mutually cooperating primary control component (511A, 511B) that are configured to diagnose (QA) each other's integrity status, and in that it

  • Publication number: 20230073739
    Abstract: A brake control unit (50) is provided to drive a brake actuator. The brake control unit comprises a primary control branch (510) with a primary inverter (512) and a primary EMI-filter (517) and a secondary control branch (520) with a secondary inverter (522) and a secondary EMI-filter (527). The primary control branch is configured to provide drive signals (D10) to the brake actuator in a normal operational mode. The secondary control branch (510) is configured to provide drive signals to the brake actuator in the at least a second operational mode. During the first, normal operational mode, both the primary EMI-filter and the secondary EMI-filter are coupled with their input to the power source. Therewith an improved reduction of conducted electromagnetic interference is achieved.
