A method for operating a braking assistance system of a vehicle, wherein the braking assistance system assists a braking of the vehicle by a vehicle braking device in the event of a hazard braking. To differentiate between the hazard braking and a normal braking, at least two variables, representing a braking demand of a driver of the vehicle, are ascertained and a threshold value is established for each variable wherein hazard braking is recognized when at least the two variables exceed their particular threshold value, whereupon an automated braking intervention by the braking assistance system is initiated with the aid of the vehicle braking device. Furthermore, at least one driving-situation variable representing the instantaneous driving situation of the vehicle is ascertained and the at least two threshold values are changed depending on the at least one driving-situation variable.

A vehicle brake system, including: a first hydraulic-pressure control mechanism and a second hydraulic-pressure control mechanism configured to control a braking force; and a controller including a first-abnormal-state detecting device configured to detect whether the first hydraulic-pressure control mechanism is in a first abnormal state, a second-abnormal-state detecting device configured to detect whether the first hydraulic-pressure control mechanism is in a second abnormal state that the first hydraulic-pressure control mechanism reaches before reaching the first abnormal state, and an assist control device configured to control the second braking-force control mechanism so as to control the braking force when an assist wait time elapses after the second-abnormal-state detecting device has detected that the first hydraulic-pressure control mechanism is in the second abnormal state, the assist wait time being determined based on a temperature of a working fluid obtained by a temperature obtaining device of the brake system.

A method for defining at least one characteristic curve of a pressure-medium-actuated brake system of a vehicle, the curve representing a relationship between a brake pressure and a brake demand, and for operating a pressure-actuated brake system of a vehicle, in which at least one brake cylinder can be supplied with a pressurized medium under a braking pressure, and in which the braking pressure is formed based on at least one such characteristic curve, and to a pressure-actuated brake system of a vehicle in which at least one brake cylinder can be supplied with a pressurized medium under a braking pressure.

A method for controlling brakes may comprise receiving, by a controller, a yaw rate from an inertial sensor, calculating, by the controller, a force correction, calculating, by the controller, a pressure correction, and adjusting, by the controller, a pressure command for a brake control device.

The present disclosure provides an auto-braking system which includes a braking device, a receiver, and a controller. The controller includes a determining portion, a verifying portion and an executing portion. The determining portion determines whether a vehicle will violate a red signal of the traffic light based on the traffic light state information. The verifying portion verifies the traffic light state information is valid by comparing the traffic light state information with the image of the traffic light captured by the sensor. The executing portion executes a first braking control to slow the vehicle at a first deceleration rate when the determining portion determines that the vehicle will violate a red signal. The executing portion executes a second braking control to slow the vehicle at a second deceleration rate to stop at a specified position when the verifying portion verifies that the traffic light state information is valid.

Systems and methods use cameras to provide autonomous navigation features. In one implementation, a method for navigating a user vehicle may include acquiring, using at least one image capture device, a plurality of images of an area in a vicinity of the user vehicle; determining from the plurality of images a first lane constraint on a first side of the user vehicle and a second lane constraint on a second side of the user vehicle opposite to the first side of the user vehicle; enabling the user vehicle to pass a target vehicle if the target vehicle is determined to be in a lane different from the lane in which the user vehicle is traveling; and causing the user vehicle to abort the pass before completion of the pass, if the target vehicle is determined to be entering the lane in which the user vehicle is traveling.

Systems and methods for a braking a vehicle. In one example, the braking system includes a friction braking system, a regenerative braking system, and an electronic processor. The electronic processor is communicatively coupled to the friction braking system and the regenerative braking system. The electronic processor is configured to receive a driver brake request and determine a brake failure state. The brake failure state indicates a brake failure. In response to determining the brake failure state, the electronic processor applies a braking force based on the driver brake request. The braking force includes a frictional braking force generated by the friction braking system and a regenerative braking force generated by the regenerative braking system.

When a brake system on a commercial vehicle, lateral acceleration and/or yaw of the vehicle are monitored and compared to a first predetermined threshold. If the first predetermined threshold is exceeded, a precharge command is sent to the brake system to precharge one or more air chambers by temporarily deactivating a modulator valve and activating an antilock traction relay valve in order to charge the air chambers up to a level permitted by the modulator valve. Upon detecting a panic braking event, a command signal is sent to the brake system to release the precharged air to facilitate braking.

Systems and methods for aircraft braking are disclosed. The systems and methods may comprise a control mode executive configured to receive a pedal input and calculate a gear deceleration command comprising a desired deceleration rate based on the pedal input; a pedal deceleration controller in electronic communication with the control mode executive configured to receive the gear deceleration command from the control mode executive and calculate a gear pedal command based on at least one of the gear deceleration command and a deceleration feedback; and a pedal executive in electronic communication with the pedal deceleration controller configured to receive the gear pedal command, and generate a pedal braking command based on the gear pedal command.

In a monitoring apparatus, a disparity calculator obtains, for each point of a target object, a pair of matched pixel regions in respective base image and reference image corresponding to the point of the target object. The disparity calculator calculates a disparity of each of the matched pixel regions of the base image relative to the corresponding matched pixel region of the reference image. A distance calculator corrects the calculated disparity of each of the matched pixel regions of the base image in accordance with a tolerable disparity range for the disparity to thereby increase the calculated disparity of the corresponding one of the matched pixel regions of the base image. The distance calculator calculates the depth distance of each point of the target object relative to the vehicle as a function of the corrected disparity of the corresponding one of the matched pixel regions.
