A method of vehicular control includes providing a camera and a control at a vehicle, and maneuvering the vehicle along a road while capturing image data via the camera. Image data captured by the camera is processed at the control to determine presence of a stopping area ahead of the vehicle and being approached by the vehicle as the vehicle is maneuvered along the road. Responsive to determination of presence of the stopping area, the operating capacity of the vehicle engine is reduced so that the engine operates at reduced capacity as the vehicle moves toward and stops at the determined stopping area. After stopping the vehicle at the stopping area, the control determines if a hazard is present in the field of view of the camera. Responsive to determining that no hazard is present, the operating capacity of the engine is restored to its normal operating capacity.

Steering a vehicle may include applying a net brake-steering force to a steered wheel sufficient to affect a steering moment upon the steered wheel sufficient to move the steered wheel away from a zero steering angle, and resisting movement of the steered wheel back toward the zero steering angle.

A method for ascertaining a torque loss of an electromechanical brake booster of a braking system, including ascertaining when a user of the braking system requests a brake pressure build-up in at least one wheel brake cylinder of the braking system, using the electromechanical brake booster, by actuating a brake actuation element of the braking system; and optionally determining an actual value with regard to the torque loss of the motor of the electromechanical brake booster, taking into account at least one provided sensor variable with regard to a motor torque of a motor of the electromechanical brake booster, a change over time of a rotation speed of the motor of the electromechanical brake booster, and/or a master brake cylinder pressure that is present in a master brake cylinder of the braking system.

In a method for providing the application force generated by a parking brake, which is at least partially generated by an electromechanical brake device having an electric brake motor, a retensioning process is terminated in the event that (i) the motor current exceeds a limit value or (ii) the rotational speed of the motor drops below a limit value.

Provided is a brake device capable of maintaining pads and a rotor in a desired positional relationship. When receiving a release request within a time period from start of execution of an application request to detection of contact between brake pad and a disc rotor, a parking brake control device inhibits execution of the release request, and executes the release request after detection of the contact between the brake pad and the disc rotor. Further, when receiving the application request within a time period from start of execution of the release request to detection of separation between the brake pad and the disc rotor, the parking brake control device inhibits execution of the application request, and executes the application request after detection of the separation between the brake pad and the disc rotor.

The invention relates to an actuator system, in particular an electromechanical parking brake system, comprising an actuator, wherein the actuator is driven by a direct current motor that can be driven in both directions of rotation, wherein a control unit for controlling the movement of the direct current motor in an open-loop or closed-loop manner is provided. The core of the invention is that one or more pieces of information are supplied to a control unit, said information allowing the application force exerted by the electromotive actuator to be determined and compared to a predetermined minimum application force, and wherein the control unit emits at least one piece of information, signal or the like for requesting an auxiliary actuation to peripheral systems, components and/or electronic control units after the target to actual value comparison has shown that the determined, set application force is smaller than the predetermined minimum application force.

This hydraulic braking device is provided with: a tubular cylinder; an assisting piston, which is housed in the cylinder so as to be able to move reciprocally, faces a reservoir formed inside the cylinder, and assists a master piston, in a master cylinder, that generates hydraulic pressure for generating a braking force by reciprocally moving from one side to the other as a result of a fluid flowing into the reservoir from a supply source; and a seal member, which is elastically deformable and which seals the reservoir. When the assisting piston is at a location on one side, the reservoir is compartmentalized into a first chamber that communicates with the supply source, and a second chamber that communicates with the first chamber through a restricting flow passage, and the seal member seals the second chamber.

A stop-start control system for a vehicle includes a camera disposed at the vehicle and having a field of view exterior and forward of the vehicle. A control includes an image processor operable to process image data captured by the camera. Responsive to image processing of captured image data, the control determines the presence of a stopping area ahead of the vehicle and being approached by the vehicle. Responsive to determination of the presence of the stopping area ahead of the vehicle and being approached by the vehicle, and responsive to determination that the driver of the vehicle releases the accelerator pedal of the vehicle so the vehicle is coasting toward the determined stopping area, the control causes the engine to at least partially shut off.

A disc brake for a commercial vehicle includes a pneumatic brake cylinder, a brake disc, a brake caliper, an application device and brake pads. The brake caliper engages over the brake disc and the application device, which can be actuated by the brake cylinder, is arranged in the brake caliper, by which the brake pads can be pressed against the brake disc on both sides during braking. An extendable and retractable piston rod of the brake cylinder is in engagement with the brake application device and the brake caliper is detachably fastened to the brake cylinder by a fastening device. The fastening device includes at least one screw with a screw head, a screw shank and an external thread formed on the screw shank and at least one bore formed in or on the brake cylinder with an internal thread, into which the screw shank is screwed with the external thread, wherein the screw head is locked on a counter surface of the brake caliper.
