An apparatus for controlling a vehicle includes: a sensor that obtains vehicle surrounding environment information and vehicle driving information; and a controller that determines whether an engagement of an Electronic Parking Brake (EPB) is possible based on the vehicle driving information, performs control for preventing a slip based on the vehicle surrounding environment information upon determining that the engagement of the EPB is impossible, calculates a steering angle for preventing the slip, transmits the steering angle to a portable terminal, receives a steering control command from the portable terminal, and controls steering based on the received steering control command.

The invention relates to a method for decelerating a motor vehicle at least during emergency braking, in which method a first braking torque is applied to at least one front wheel of the motor vehicle by means of at least one service brake system of the motor vehicle. According to the invention, at least one parking brake different from the at least one service brake system is activated by a control apparatus of the motor vehicle and a second braking torque is thereby applied to the at least one front wheel while the first braking torque is applied. A further aspect of the invention relates to a motor vehicle.

A method for estimating a braking force applicable between pad and brake disc by an electric parking-braking system of a vehicle is described. The method may include detecting, by one or more sensors of electric quantities of an electric motor, an electric current delivered to the electric motor and an instantaneous value of an electric voltage for electrically supplying the electric motor, during a parking-braking operation. The parking-braking operation may have a first non-contact stage between a first pair of pads of a first brake caliper and a first brake disc. The parking-braking operation may also have a second contact stage between the first pair of pads of the first brake caliper and the first brake disc.

The present invention relates to an electronic parking brake device for a vehicle, in particular a utility vehicle. As a function of at least one operating state of a towing vehicle parking brake supply line and/or a trailer parking brake supply line, a towing vehicle parking brake control valve is activatable by means of a control unit in such a way that a towing vehicle parking brake supply line can be deaerated or aerated by the towing vehicle parking brake control valve. By manually actuating a trailer parking brake control element, a trailer parking brake control valve is activatable by means of the control unit in such a way that a trailer parking brake supply line can be deaerated or aerated by the trailer parking brake control valve. The present invention also relates to a method for operating the above electronic parking brake device for a vehicle.

The present disclosure relates to a composite cable for a vehicle and a composite cable assembly, which are capable of simultaneously providing a communication function and power to an electronic parking brake (EPB) and an anti-lock brake system (ABS) for use in a vehicle, and maximizing electromagnetic compatibility (EMC) shielding performance between internal components or external cables.

An electromechanical brake device has a brake caliper and a pressure piston mounted in the brake caliper such that it can move in a clamping direction, wherein the brake device has an electromechanical clamping device, wherein the clamping device is supported, on one side, on the pressure piston and is designed to apply to the pressure piston a force acting in the clamping direction. It is provided that the brake device has at least one hydraulically sealed, fluid-filled cavity, wherein the clamping device is supported, on the other side, indirectly on the brake caliper via the fluid-filled cavity, and wherein a pressure sensor is hydraulically connected to the fluid-filled cavity and is designed to calculate the fluid pressure inside the fluid-filled cavity.

A two-wire connecting system for linking an Electronic Parking Brake and Wheel Speed Sensor to a vehicle control module utilizing a ternary analogous signal. One or more diodes are implemented in the connecting system to selectively power the Electronic Parking Brake and Wheel Speed Sensor. By halving the number of wires, the connecting system is lighter than traditional 4-wire connecting systems that link an Electronic Parking Brake and Wheel Speed Sensor with a control module.

A system on a tractor for controlling trailer service brakes comprises a manually operated trailer brake switch, a first electropneumatic valve in communication with a pressure source and a controller. The controller has an input communicating with the trailer brake switch, an output communicating with the electropneumatic valve and control logic. The control logic receives an input from the trailer brake switch indicating a driver's request to apply the trailer service brakes of the combination vehicle, determines if a predetermined condition exists and transmits a signal to the output to the electropneumatic valve. The electropneumatic valve transmits pressure to a trailer service control line to actuate the trailer service brakes in response to the trailer brake switch and existence of the predetermined condition.

A method for operating a brake system of a motor vehicle includes actuating a first actuating device of the brake system, exerting an electromechanical braking force to decelerate the motor vehicle in an event of a fault in the hydraulic braking device and when the first actuating device is actuated, and generating the electromechanical braking force after a start of the actuation of the first actuating device for a minimum generation period and/or generating the electromechanical braking force after an end of the actuation of the first actuating device for an additional continued generation period. The brake system includes a hydraulic braking device, an electromechanical braking device, and a first actuating device, in particular a brake pedal.

A cable-pull actuation system for a parking brake may have a body which houses an electric motor device. A rod, adapted to operate along an actuation direction, at a first end thereof, an actuation member of a drum brake and/or of a parking brake. A transmission device may operatively connect the electric motor device to a second end of the rod which is translationally integral with a screw. The screw may be engaged with a nut screw rotationally actuated by the transmission device. A pre-loading device may act in contrast on the screw. The pre-loading device may be compressively pre-loaded to exert a pre-load traction on the rod to offset variations of load on the rod. The pre-loading device may be configured to exert a thrust action on the rod following the annulment of axial clearances for an incremental compression of the pre-loading device with respect to the pre-load value.
