Abstract:
A braking assistance system for a vehicle towed by a towing vehicle. The braking assistance system includes at least one sensor configured to be coupled to the towed vehicle and to detect information about at the towed vehicle and the towing vehicle, and an electronic control unit having a processor. The electronic control unit is in electronic communication with the sensor to receive information about the towed vehicle and the towing vehicle. The processor is configured to determine an electrical connection between the towing vehicle and the towed vehicle, determine a deceleration of the towed vehicle and the towing vehicle based on the information from the at least one sensor, identify a brake assist situation, and initiate a brake control operation to control braking of the towed vehicle during the brake assist situation.

Abstract:
A method for controlling a braking system in a vehicle during a panic braking event includes the steps of determining a magnitude of force applied to the brake pedal, determining a first level of braking that would result from the magnitude of force applied to the brake pedal if there were no panic braking event, and applying a second level of braking equal to the lesser of the following: the maximum braking capacity, and the level of braking that would result from the magnitude of force applied to the brake pedal if there were no panic braking event, multiplied by a predetermined constant.
Abstract:
A system for controlling a brake force of a vehicle. In one embodiment, the system includes an electronic control unit including a controller, a plurality of sensors in electronic communication with the controller. Each of the sensors transmits sensor data to the controller. A user interface and a driver recognition system are in electronic communication with the controller, and a computer readable memory stores instructions executed by the controller. The instructions cause the controller to evaluate a driver identification data received from the driver recognition system, a driver preference data received from the user interface, and the sensor data received from the sensors. The instructions further cause the controller to classify and select a driver or a driving pattern class, execute a control algorithm to determine a driver dependent brake force based on at least one of the selected driver or driving pattern class, the driver preference data, and the driver identification data, and to regulate the brake force of the vehicle based on the driver dependent brake force.
Abstract:
In a control device of a braking device, a brake force holding control that holds a brake force generated by a braking device main body to wheels of a vehicle to a predetermined value or more is executed based on a change amount per unit time of an operation amount of a brake operation member. Accordingly, since the brake force holding control that holds the brake force to the predetermined value or more is executed by the braking device main body based on at least a change amount per unit time of an operation amount of the brake operation member, holding of the brake force can be appropriately executed regardless of an operation state.
Abstract:
A vehicle brake control system is provided with a preceding object detecting section, a running condition detection section, a steering actuation state detecting section, a braking force detecting section, a preceding object avoidability determining section and a braking force control section. The preceding object avoidability determining section determines a possibility of avoiding the preceding object by steering and reducing the current braking force acting on the host vehicle based on the position of the preceding object, the running condition of the host vehicle, the braking force applied to the host vehicle and the steering wheel actuation state that are detected. The braking force control section reduces the current braking force applied by the host vehicle braking system when the preceding object avoidability determining section determines that the preceding object can be avoided by steering and reducing the current braking force acting on the host vehicle.
Abstract:
A system and method for assisting a driver operating a vehicle traveling on a road includes a reaction force device configured to determine a first reaction force value and a second reaction force value, a weighting device configured to weight the second reaction force value, a reaction force selection device configured to select one of the first and weighed second reaction force values, a driver controlled input device manually operable by the driver, and an actuator coupled to the driver controlled input device and configured to transmit the selected one of the first and weighed second force values to the driver by a reaction force input via the driver controlled input device.
Abstract:
Safety driving evaluation systems, methods, and programs count a frequency of a braking operation of a vehicle and determine whether each braking operation is a sudden braking operation. The systems, methods, and programs calculate a sudden braking percentage. The systems, methods, and programs determine whether a vehicle deceleration frequency is low for a road where the sudden braking occurred, and correct the sudden braking percentage to a higher value if the vehicle deceleration frequency is determined as low. The systems, methods, and programs acquire evaluation information based on the sudden braking percentage.
Abstract:
In a method for determining at least one, preferably however several driver-independent interventions in a vehicle system, a risk calculator is used, whose input is supplied with predetermined vehicle data, ambience data, current vehicle and driver data, occupant data or data of persons outside the vehicle, or similar data. The risk calculator issues an evaluation of the risk situation of the vehicle and its occupants or the persons outside the vehicle based on said data and, in accordance with the evaluation and optional additional criteria or weightings, outputs driving signals controlling actuators that modify or trigger the driving behavior of the vehicle and/or the occupant protection system and/or protection means for other traffic participants (pedestrians, cyclists, etc.) in such a way that maximum protection is obtained for the persons and the vehicle according to a priority control.
Abstract:
An apparatus for controlling brakes, includes a first brake circuit for supplying brake fluid, pressure-increased by a booster, to a wheel-brake cylinder, a first control valve disposed in the first brake circuit for establishing and blocking fluid communication between a master cylinder and the wheel-brake cylinder, a second brake circuit arranged in parallel with the first brake circuit for supplying brake fluid, pressure-increased by a fluid-pressure source, to the wheel-brake cylinder, and a second control valve disposed in the second brake circuit for establishing and blocking fluid communication between the fluid-pressure source and the wheel-brake cylinder. Also provided is a control unit, which is configured to selectively control the first and second control valves when building-up wheel-cylinder pressure, and further configured to build-up the wheel-cylinder pressure by operating the fluid-pressure source when at least the second control valve is controlled to a valve-open position.
