Abstract:
A method for operating a braking force generator for a motor vehicle having a hydraulic braking system. The braking force generator, in a first working mode, builds up braking force independently, and in a second working mode, builds up braking force to assist the driver. A strategy for operating the braking force generator is adapted depending on a driving situation. A corresponding apparatus is also provided.
Abstract:
A brake system for controlling the brake performance of a vehicle includes a brake, a control unit connected to one or more external condition sensors, and one or more brake performance sensors. The external condition sensors obtain parameters regarding conditions surrounding the vehicle, which are monitored by a driver assistance unit to estimate a probability value that the brakes should be applied to avoid a collision. The brake performance sensors obtain parameters regarding conditions of the brake. The control unit receives the obtained parameters from the external condition sensors and the estimated probability value and determines a surrounding threat level of the vehicle. The control unit receives the obtained parameters from the brake performance sensors and determines a brake performance level, and heats the at least one brake if the brake performance level is below a first level and the surrounding threat level is above a second level.

Abstract:
A method for output of haptic information to a driver of a motor vehicle via a brake pedal includes ascertaining, based on signals of an environment-sensor system, imminence of a traffic situation that poses a potential risk to the motor vehicle, and modifying, during a driving of the motor vehicle, independent of a driver input, and in response to the ascertained imminence of the traffic situation, a characteristic of the brake pedal of the motor vehicle.
Abstract:
A system, method, and apparatus for brake load alleviation amongst at least one first brake and at least one second brake is disclosed. The method involves sensing an amount of brake pedal application in response to engagement of at least brake pedal. The method further involves determining whether the amount of brake pedal application is greater than a brake pedal application threshold value. Also, the method involves generating a brake application profile, when it is determined that the amount of brake pedal application is greater than the brake pedal application threshold value. The brake application profile indicates that actuation of at least one first brake is delayed by a first time delay, and that actuation of at least one second brake is delayed by a second time delay. Further, the method involves actuating at least one first brake and at least one second brake according to the brake application profile.
Abstract:
This vehicle control device is provided with: a control unit for executing one-pedal control, that is, the control for accelerating a vehicle when a single pedal is depressed from a predetermined reference point of a pedal stroke, and for decelerating the vehicle when the pedal is released from the reference point; and a determination unit for determining whether or not a rate of change in a pedal operation amount when the pedal is released is equal to or greater than a first threshold value. The control unit performs control for increasing a braking force when the rate of change is equal to or greater than the first threshold value.
Abstract:
Described herein is a vehicle system configured to identify and mitigate inappropriate driving behavior. In some embodiments, the vehicle system may receive input information from one or more input sensors. The vehicle system may identify driving behaviors related to a vehicle from the received input. The vehicle system may determine whether the driving behaviors are inappropriate in light of one or more conditions affecting the vehicle. Upon identifying inappropriate behavior, the vehicle system may generate a set of corrective actions capable of being executed to mitigate the inappropriate driving behavior.
Abstract:
A parking assist system includes an electronic control unit configured to: estimate first extending directions of obstacles respectively located on right and left sides of a target parking space in a state where a host vehicle moves across in front of the target parking space; calculate a planned moving path based on the estimated first extending directions; as the host vehicle is guided into the target parking space, estimate second extending directions of the obstacles respectively located on the right and left sides of the target parking space while updating the second extending directions; determine whether the estimated and updated second extending directions satisfy a predetermined condition; and when the updated second extending directions satisfy the predetermined condition, update the planned moving path by using the updated second extending directions instead of the first extending directions or the second extending directions before being updated.
Abstract:
A motor vehicle includes a plurality of wheels and a brake system, which has brakes, which can be hydraulically actuated and are each associated with a wheel. The brakes can be actuated by at least one brake circuit which can be operated by a brake booster. The brake booster can be actuated by a brake pedal to be pressed by the driver. At least one pressure-generating and/or pressure-accumulating device, controlled by a control device to modulate the hydraulic pressure within the brake circuit. A second pressure-generating and/or pressure-accumulating device is provided in the brake circuit to automatically increase the pressure within the brake circuit in dependence on demand independently of the first pressure-generating and/or pressure-accumulating device, when a malfunction is detected in the brake system.
Abstract:
An autonomous braking system includes a detecting module, a tracing module, a collision path prediction module, a memory register, a collision time prediction module and a decision module. The detecting module recognizes multiple objects located ahead of a vehicle, and then the tracing module traces the moving objects. The collision path prediction module is used to obtain a possible collision range and a non-collision range. The memory register records the coordinate of the objects located within the possible collision range. When one of the objects moves out of the possible collision range, its data is instantaneously removed from the memory register. The collision time prediction module predicts a collision time between the vehicle and each of the objects. The decision module determines if a brake assist is activated in accordance with the collision time.
