Methods and apparatus to control braking of a vehicle during low deceleration operations
Methods and apparatus to control braking of a vehicle during low deceleration operations are disclosed. A disclosed apparatus includes a controller configured to determine a deceleration of a vehicle, compare the deceleration to a threshold, and modulate, at a predetermined frequency, a brake pressure of the vehicle in response to the deceleration being below the threshold.
SYSTEM FOR CONTROLLING AN ELECTRIC PARKING BRAKE BY PULSE WIDTH MODULATION
A control system for controlling an electric parking brake system of a motor vehicle having at least two brakes designed to be mounted near wheels of the motor vehicle, each brake comprising a parking brake actuator actuated by an electric motor; the control system comprises a control unit (UC) for controlling electric motors, such that, when an instruction to apply the parking brake is issued, the electric motors are supplied with power in order to actuate the actuator and allow application of the brakes. The control unit is designed to control the electric motors by pulse-width modulation at least in some of
APPARATUS FOR REDUCING A SPEED OF A MOTOR VEHICLE
The disclosure relates to an apparatus configured to reduce a speed of a motor vehicle to a predetermined value at a predetermined position. The apparatus includes a position-capture device configured to establish the predetermined position by evaluating map data relating to a planned route of the motor vehicle, and a target-setting device for establishing the predetermined value at the predetermined position.
METHOD FOR OPERATING A VEHICLE
A method for operating a vehicle, a braking device, including a parking brake as one element and a brake booster as another element for actuating a service brake of the vehicle, being actuated to decelerate the vehicle, so that a braking force, which decelerates the vehicle, is generated with the aid of the braking device, during deceleration of the vehicle, at least one of the elements of the baking device being controlled in such a way that the generated braking force varies over time. A control device for a braking device of a vehicle, a braking system for a vehicle, and a computer program, are also described.
System for controlling an electric parking brake by pulse width modulation
A control system for controlling an electric parking brake system of a motor vehicle having at least two brakes designed to be mounted near wheels of the motor vehicle, each brake comprising a parking brake actuator actuated by an electric motor; the control system comprises a control unit (UC) for controlling electric motors, such that, when an instruction to apply the parking brake is issued, the electric motors are supplied with power in order to actuate the actuator and allow application of the brakes. The control unit is designed to control the electric motors by pulse-width modulation at least in some of the actuation phases of the parking brake actuators.
