A system for providing real-time alerts or actions comprises an image capturing device and a processor and a memory. The image capturing device is for capturing an image during vehicle operation and of an expected driver location. The processor is configured to: 1) detect a face of a driver in the image; 2) determine a set of face data from the image; and 3) determine authentication based at least in part on the set of face data. The memory is coupled to the processor and configured to provide the processor with instructions.

A device for a hydraulic actuating system, e.g., a motor vehicle brake, a clutch or a gear selector, may include the following components arranged in one housing, forming a main module: at least one pressure supply device driven by an electric motor drive, and a valve arrangement comprising at least one solenoid valve. The device may further include an electrical control unit (ECU) and valve output stages and sensors. The main module may be electrically and/or hydraulically connected to at least one further system component, which system component may include an actuating device and a travel simulator.

This braking control device comprises a first unit that outputs supply pressure in accordance with the amount of operation of a braking operation member, a second unit that is provided between the first unit and a wheel cylinder and that increases the supply pressure and outputs a wheel pressure to the wheel cylinder, a communication bus that transfers signals between the first unit and the second unit, an operation amount sensor that detects the amount of operation, and a supply pressure sensor that detects the supply pressure. In the braking control device, the first unit controls the supply pressure so as to bring the supply pressure close to a target pressure calculated on the basis of the amount of operation. When the first unit is abnormal, the second unit increases the wheel pressure on the basis of the deviation between the target pressure and the supply pressure.

This braking control device comprises: a first unit that outputs a supply pressure in accordance with the amount of operation of a braking operation member; a second unit that is provided between the first unit and a wheel cylinder, and adjusts the supply pressure to output a wheel pressure to the wheel cylinder; a communication bus for communicating signals between the first unit and the second unit; an operation amount sensor that detects the operation amount; and a supply pressure sensor that detects the supply pressure. In the braking control device, when there is an abnormality in signal communication, the second unit calculates a target pressure on the basis of the operation amount and adjusts the wheel pressure on the basis of the difference between the target pressure and the supply pressure.

This braking control device comprises a first unit for outputting a supply pressure in accordance with operation displacement of a braking operation member, a second unit between the first unit and a wheel cylinder to increase the supply pressure and output a wheel pressure to the wheel cylinder, a displacement sensor for detecting the operation displacement, and a supply pressure sensor for detecting the supply pressure. The first unit selects either a first mode in which the operation displacement and the supply pressure are independent or a second mode in which the operation displacement and the supply pressure are linked. When the displacement sensor is normal, the first unit selects the first mode and increases the supply pressure based on the operation displacement. When the displacement sensor is not normal, the first unit selects the second mode, and the second unit increases the wheel pressure based on the supply pressure.

A braking control device for vehicles that comprises: a first unit that outputs a supply pressure in accordance with the amount a braking operation member is operated; a second unit that is provided between the first unit and a wheel cylinder, regulates the supply pressure, and outputs a wheel pressure to the wheel cylinder; a communications bus that transfers signals between the first unit and the second unit; an operation amount sensor that is connected to the first unit and detects the operation amount; and a supply pressure sensor that is connected to the second unit and detects the supply pressure. The first unit calculates a target pressure on the basis of the operation amount, obtains the supply pressure from the second unit via the communications bus, and performs feedback control such that the supply pressure matches the target pressure.

The present disclosure relates to a motor driving circuit of an electronic parking brake system, which is configured to include a first motor and a second motor for releasing or applying a parking brake applied to different wheels, respectively; and a first ECU and a second ECU for controlling the driving of the first motor and the second motor, respectively, wherein the second ECU is prevented from intervening in the driving of the first motor and the second motor while the first ECU drives the first motor and the second motor, and controls the driving of the first motor and the second motor only when there is an abnormality in the first ECU.

A method and apparatus are provided for optimizing one or more object detection parameters used by an autonomous vehicle to detect objects in images. The autonomous vehicle may capture the images using one or more sensors. The autonomous vehicle may then determine object labels and their corresponding object label parameters for the detected objects. The captured images and the object label parameters may be communicated to an object identification server. The object identification server may request that one or more reviewers identify objects in the captured images. The object identification server may then compare the identification of objects by reviewers with the identification of objects by the autonomous vehicle. Depending on the results of the comparison, the object identification server may recommend or perform the optimization of one or more of the object detection parameters.

A device for monitoring the status of a railcar handbrake having a hand operated handle, which device has a load bearing member configured to be inserted in the linkage of a railcar handbrake system so that the force applied to the brake system passes through the load bearing member. A strain gauge mounted on the load bearing member measures the strain. The information from the strain gauge is indicative of the force applied by the handbrake to the brake and is used to determine the status of the handbrake. Means for determining motion of the railcar is also provided. In one form, if it is determined that the brake is on and the railcar is in motion, information, such as an alarm, is transmitted. A system and method of monitoring a railcar handbrake are also provided.
