    Abstract: A method for the drive control of actuators of at least one wheel of a vehicle. The method includes: sensing a desired acceleration; sensing a vehicle velocity of the vehicle; sensing a wheel velocity of the wheel determining a status description of the wheel from the wheel velocity and a wheel acceleration; determining a first value of a target wheel acceleration from the status description, a slip of the wheel, and the desired acceleration; determining a second value of the target wheel acceleration from the wheel velocity, the wheel acceleration and the slip, wherein the second value is a function of correction factors of at least one matrix; and determining a third value of the target wheel acceleration, which value controls the actuators of the at least one wheel, wherein the third value is a function of the first value and of the second value.

    Abstract: A computer system comprising a processor device configured to control an acceleration of a vehicle is provided. The vehicle comprises a set of auxiliary brakes. The processor device obtains an acceleration condition of the vehicle. The acceleration condition being indicative of any one out of: an acceleration of the vehicle, the absolute value of which is below a predetermined acceleration limit value; a predefined positive acceleration of the vehicle, and a predefined negative acceleration of the vehicle. The processor device is further configured to, in response to determining that the vehicle can be controlled in accordance with the obtained acceleration condition using the set of auxiliary brakes, control the set of auxiliary brakes in accordance with the obtained acceleration condition of the vehicle.

    Abstract: Aircraft braking system architecture comprising:



    a brake comprising electromechanical actuators (1, 2);
    a principal control channel (6) and an alternative control channel (7) comprising electrical components that are at least partly different and adapted to provide respectively a principal braking control function and an alternative braking control function that are at least partly different;
    power modules (15, 16) comprising electrical components that are at least partly different and adapted to generate electrical power supply currents (I1, I2) on the basis of principal control signals or alternative control signals;
    a surveillance unit (8) adapted to ensure that in normal operation the principal control signals are used and that in the event of a fault the alternative control signals are used to generate the electrical power supply currents.

    Abstract: A motor control device is provided with: an electric motor which drives an applying mechanism for applying torque to the wheels of a vehicle, and has three coils; a drive circuit that supplies current individually to the three coils; and a controller that controls the drive circuit on the basis of the operation amount of an operating member of the vehicle, and adjusts the output of the electric motor. When the vehicle is stopped, the controller executes swing control to periodically increase or decrease the rotary motion of the electric motor, even if the constant state of the operation amount is continued after the operation amount is constant, and the power generated by the applying mechanism and the power received by the applying mechanism are equalized and the rotary motion of the electric motor has stopped.

    Abstract: A brake ECU of a vehicle braking control device, during execution of brake pressurization control, performs actuation restriction control that restricts actuation of a motor as an arbitrary upstream fluid pressure (M/C pressure) that is the brake pressure input from the M/C side of the brake fluid pressure control actuator becomes higher. The brake ECU has a threshold value changing unit that sets at least the starting threshold value at a high level when the upstream fluid pressure (M/C pressure) is high compared to when low, and as actuation restriction control actuates the motor to pump out the brake fluid from inside of the reservoirs when the reservoir fluid volume exceeds the starting threshold value, and stops the motor when the reservoir fluid volume equals the stop threshold value.
