In a collision avoidance control device for a vehicle according to an embodiment, for example, when receiving a brake request from a driver while a brake device is given an operational instruction corresponding to a third deceleration, a brake controller controls at least the brake device to decelerate the vehicle at a deceleration calculated by adding the third deceleration and a fourth deceleration corresponding to the brake request.

Provided is an electric brake device capable of adjusting a clearance without making a driver feel discomfort, in a vehicle equipped with the electric brake device. A control device (2) of this electric brake device (DB) includes: a brake operation amount detector (24) to detect an operation amount to a brake operation member (27) of the vehicle; and an operation record flag storage unit (19) to store an operation record flag indicating a record of a latest operation performed by the driver to the brake operation member (27), on the basis of the operation amount detected by the brake operation amount detector (24). The control device (2) further includes a target clearance determination unit (17) to determine a target clearance with reference to the operation record flag stored in the operation record flag storage unit (19).

Vehicles according to at least some embodiments of the disclosure include a sensor, and a computing device comprising at least one hardware processing unit. The computing device is programmed to perform operations comprising capturing an image with the sensor, identifying an object in the image, and in response to an accuracy of the identification meeting a first criterion, pre-loading a braking system of the autonomous vehicle. In some aspects, the computing device may predict that an object not currently within a path of the vehicle has a probability of entering the path of the vehicle that meets a second criterion. When the probability of entering the path meets the second criterion, some of the disclosed embodiments may pre-load the braking system.

A method is described for determining a control signal for a controllable pressure medium control valve of an electronically slip-controllable power braking system. The underlying power braking system is equipped with an actuating unit including a displaceable actuating element, the displacement of the actuating element determining a throughput of pressure medium through the pressure medium control valve. In the opened state, the pressure medium flowing through the pressure medium control valve causes flow forces on a valve closing element. Under certain circumstances, these flow forces have a closing effect on the valve closing element, thus throttling the possible pressure medium throughput, and cause undesirably high pressure differences in the interior of the pressure medium control valve. To avoid these effects, it is provided that the pressure medium control valve be controlled using a control signal dependent on the speed of an actuation of the actuating element.

Methods of assessing driver behavior include monitoring vehicle systems and driver monitoring systems to accommodate for a slow reaction time, attention lapse and/or alertness of a driver. When it is determined that a driver is drowsy, for example, the response system may modify the operation of one or more vehicle systems. The response system can modify the control of two or more systems simultaneously in response to driver behavior.

A brake booster for a brake system of a vehicle, having a first input piston component, and a valve body. The brake booster has a second input piston component, which is pushed away from the first input piston component in the braking direction using a compression spring, and a locking mechanism is embodied such that when the differential travel between the booster travel and the input travel is smaller than a predefined first limit value, the second input piston component is adjustable using the compression spring together with the valve body away from the first input piston component, and when the differential travel exceeds the first limit differential travel, the second input piston component is locked in place on the first input piston component.

An electronic parking brake (EPB) system having expanded functionality, such that after a Hydraulic Electronic Control Unit (HECU) (i.e., host) commands the parking brake units to release clamping force on the brake discs, a pressure differential is generated in the rear calipers. When the normally closed valves at the HECU are opened, fluid is transferred to a low-pressure accumulator, transferring the brake fluid from the housing of the caliper. A pump is then activated to further draw fluid from the accumulator and the caliper, transferring the fluid back to the master cylinder. The suction created by the activation of the pump moves the caliper piston towards the housing and the brake pad away from the brake disc, and achieving the desired air gap.

Herein is disclosed an image-based detection system comprising, one or more image sensors, configured to receive images of a vicinity of a control; and one or more processors, configured to identify within the images a control actuator and the control; detect a trigger action of the control actuator relative to the control based on the images; and switch from a normal control mode to a safety mode according to the detected trigger action.

In a method for reducing risks in road traffic, using a motor vehicle an information signal is generated and transmitted to an analysis unit. The information signal contains a position of the corresponding motor vehicle and an associated hazard level. Using the analysis unit, the position is assigned to a route section and a risk characteristic value is determined as a function of the hazard level. Using the analysis unit, a risk signal is generated based on the risk characteristic value and provided to at least one traffic participant.

A brake system is disclosed. The brake system includes a brake stack having a stack closure pressure, a force member positioned within a cylinder, a valve configured to control the fluid pressure of the brake system, and one or more pressure transducers that generate a proportional electrical signal representative of fluid pressure within the cylinder. The brake system also includes one or more processors in electronic communication with the valve, the one or more pressure transducers, and a memory coupled to the one or more processors. The memory stores data comprising a database and program code that, when executed by the one or more processors, causes the brake system to determine the stack closure pressure of the brake stack.
