ADAPTIVE BRAKE ASSIST SYSTEM FOR A CYCLIST ON A BICYCLE BY AN APTIC FEEDBACK
Adaptive brake assist system a cyclist on a bicycle by an aptic feedback, includes a first sensor (for measuring the angular speed (.sub.1) of a first wheel of the bicycle, adapted to generate a signal representative of the angular speed of the first wheel; an actuator mountable to a portion of the bicycle, adapted to generate vibrations; a control module configured to generate a command signal of the actuator, so that the actuator vibrates at a vibration frequency (f), based on at least the signal representative of the angular speed of the first wheel (.sub.1) and based on one or more reference magnitudes (.sub.ref); and a learning module configured to determine, updating and delivering to the control module the one or more reference magnitudes (.sub.ref) based on at least the signal representative of the angular speed (.sub.1) of the first wheel.
BRAKING CONTROL DEVICE OF VEHICLE
In the case that the road surface is determined to have different friction coefficients on the left and right wheels, this braking control device performs antiskid control for adjusting the increase slope of front wheel braking torque on the side with the higher friction coefficient. A steering angle sensor detects the steering angle, and a yaw rate sensor detects the yaw rate. The device calculates a reference turning amount on the basis of the steering angle, calculates an actual turning amount on the basis of the yaw rate, and sets the increase slope on the basis of the deviation between the reference turning amount and the actual turning amount. Also, if this deviation becomes larger, a correction is made such that the set increase slope becomes smaller. Further, if the deviation becomes smaller, a correction is made such that the set increase slope becomes larger.
Method for stabilizing a tractor vehicle-trailer combination during travel
A method and device for stabilizing a tractor vehicle-trailer combination during travel, in which tractor vehicle and trailer are connected via at least one pivot joint, including: ascertaining a setpoint buckling angle for a driving-stable setpoint movement of the combination, and/or a setpoint buckling angle velocity for a driving-stable setpoint movement of the combination, between the combination or between two trailers; ascertaining an actual buckling angle for the effective actual movement of the combination, and/or an actual buckling angle velocity for the effective actual movement of the combination, between the tractor vehicle and trailer or between multiple trailers; ascertaining a deviation between the setpoint and actual buckling angles and/or between the setpoint and actual buckling angle velocities, and if the deviation exceeds a threshold value, generating a control signal to activate at least one vehicle component to control movement of the combination in a direction toward a driving-stable movement state.
Braking control device and braking control method
A braking control device is provided to automatically control a main braking device normally used to brake a host vehicle during travel and a second braking device used to maintain the host vehicle in a stopped state. The braking control device has a slip degree prediction unit and a braking device switching unit. The slip degree prediction unit predicts a possibility that the host vehicle will slip. The braking device switching unit is configured to delay a timing with which to start a reduction in a braking force of the main braking device if the slip degree prediction unit predicts a slip when switching the main braking device to the second braking device.
Vehicle control apparatus and method for controlling the same
A vehicle control apparatus and a method for controlling the same are disclosed. The vehicle control apparatus includes an inputter, a determiner, and a controller. The inputter receives an automatic vehicle hold (AVH) switch operation signal from an AVH device, and receives a current vehicle movement value sensed by a sensing device and a current vehicle brake force value of a brake device that generates brake force in response to activation of the AVH device. The determiner determines whether the received AVH switch operation signal transitions from an ON state to an AVH entry state, determines whether vehicle movement occurs on the basis of the received current vehicle movement value during an AVH retention time in the AVH entry state, and determines that the current vehicle brake force value is in an abnormal state when vehicle movement occurs. The controller receives the current vehicle movement value and the current vehicle brake force value, and transmits a command for judgment to the determiner.

METHOD AND DEVICE FOR DETERMINING BRAKING-RELATED ACTUAL VALUES OF A RAIL VEHICLE FOR CARRYING OUT A DECELERATION-CONTROLLED BRAKING WITH A CENTRAL SENSOR SYSTEM
A method and a device for determining braking-related actual values of a train assembly including multiple carriages for carrying out a deceleration-controlled braking of the train assembly, in which the longitudinal deceleration and the longitudinal slope are considered to be actual values, from which an adjustment value balancing the control deviation is determined for a control element of the brake by a deceleration controller/deceleration force controller according to a predefined setpoint value of a desired braking deceleration.
OFF-ROAD CONTROL BRAKE
Receiving, by a control unit of a vehicle, an indication to operate the vehicle in an off-road control brake mode, determining, by the control unit, a current speed of the vehicle, and controlling, by the control unit and in response to the indication and the determined current speed, an electric motor of the vehicle to output forward torque or reverse torque to maintain the current speed of the vehicle between a first threshold speed and a second threshold speed, wherein the second threshold speed is higher than the first threshold speed.

The control device is configured to perform control such that, in a case where the plurality of braking force generators perform a braking operation and there is a malfunctioning braking force generator, braking forces of the plurality of braking force generators other than the malfunctioning braking force generator are maintained or increased when an acquired value of an actual yaw rate acquired from the yaw rate detecting unit is equal to or less than a reference value, and a steering torque is applied to a steering system in a direction in which the actual yaw rate decreases when the acquired value of the actual yaw rate is larger than the reference value.
