  • Patent number: 11104311
    Abstract: A brake control system adapted for use in a motor vehicle is disclosed, which brake control system is intended to determine, while an ACC device of the motor vehicle is active and based on environmental data obtained from one or more environmental sensors associated with the motor vehicle, a braking correction value for an emergency braking profile describing the braking behaviour of the motor vehicle. The environmental sensors are adapted to provide the brake control system with the environmental data representing the area in front of the motor vehicle. The brake control system is adapted to provide a target braking profile and to determine an actual braking profile on the basis of environmental data provided during an ACC braking operation. The brake control system is further adapted to compare the target braking profile with the actual braking profile and on the basis of the comparison result to determine the braking correction value.

  • Publication number: 20200070788
    Abstract: A motor vehicle system comprising a first electric parking brake actuation unit assigned to a first vehicle wheel, and a second electric parking brake actuation unit assigned to a second vehicle wheel. The system further comprises a first control unit which includes at least one first microprocessor and which is designed to control the first electric parking brake actuation unit and does not allow the second electric parking brake actuation unit to be controlled. Furthermore, a second control unit is provided which comprises at least one second microprocessor and which is designed to control the second electric parking brake actuation unit and does not allow the first electric parking brake actuation unit to be controlled. The redundancy of the two control units increases the system safety. At the same time, the system complexity remains low since no individual control unit has to be designed to control all of the electric parking brake actuation units.
