The control system may include a plurality of cameras to acquire a plurality of images of an area in a vicinity of a vehicle; and at least one processing device configured to: recognize a curve to be navigated based on map data and vehicle position information; determine an initial target velocity for the vehicle based on at least one characteristic of the curve as reflected in the map data; adjust a velocity of the vehicle to the initial target velocity; determine, based on the plurality of images, observed characteristics of the curve; determine an updated target velocity based on the observed characteristics of the curve; and adjust the velocity of the vehicle to the updated target velocity.
SYSTEM AND METHOD FOR CONTROLLING KICK-BACK IN ELECTRIC BOOSTER TYPE BRAKE SYSTEM
The present disclosure provides a system and a method for controlling kick-back in an electric booster type brake system capable of reducing a kick-back phenomenon in which a hitting force is transmitted to a brake pedal due to a difference between a high braking hydraulic pressure already generated in a power piston of a second master cylinder by driving a motor and a low braking hydraulic pressure generated in a first master cylinder when a driver steps on a brake pedal, in a fall back situation in which electric power is not smoothly supplied to the motor due to a low voltage of a battery.
Vehicular collision avoidance control device and vehicular collision avoidance control method
A vehicular collision avoidance control device includes: a collision avoidance control unit that receives a vehicle deceleration rate that is an actual deceleration rate of a traveling vehicle and obtains a first desired deceleration rate for avoiding collision with an obstacle based on the received vehicle deceleration rate, a relative distance to the obstacle, and a target relative distance; and a brake control unit that obtains a desired deceleration rate for controlling a brake device by performing first control based on the received vehicle deceleration rate and the first desired deceleration rate and performing second control based on the first desired deceleration rate and stops the first control upon detection of a brake operation performed by a driver.
Vehicular driving assistance device
When an engine speed is less than a safeguard speed while a vehicle downhill assist control is being executed, a target speed of the vehicle downhill assist control is increased. In addition, if the target speed is greater than a vehicle speed, braking force applied to the vehicle is decreased.

Braking system architecture for aircraft
A braking system architecture for aircraft, the architecture comprising: a brake including friction members and electromechanical actuators for exerting a braking torque on the wheel; a computer situated in the fuselage of the aircraft and arranged to produce first control signals; and a junction box situated on the undercarriage, the junction box being connected to the computer and to the electromechanical actuators, the junction box being configured to receive the first control signals and to use the first control signals to produce second control signals for application to the electromechanical actuators in order to control the electromechanical actuators.
Method for controlling a brake system
A brake system comprises a cylinder-piston unit movable by an electromechanical actuator. Wheel brakes associated with at least one axle can be supplied with braking pressure via the hydraulic pressure chamber. The electromechanical actuator comprises a rotation-translation transmission and an electronically commutated synchronous machine having a stator with at least two phase windings, a rotor comprising at least one permanent magnet and at least one rotor position sensor. A torque-forming current and/or a magnetic field attenuating current are adjusted in a co-ordinate system which is fixed relative to the rotor. Voltages in the co-ordinate system are detected to serve as control variables and are transformed into a voltage phasor, which indicates for each phase winding of the stator, a voltage to be applied, and a set value for the magnetic field attenuating current is limited to a maximum value being determined from a predetermined characteristic map.
