One embodiment provides a vehicle brake hydraulic controller including: an antilock braking controlling module configured to perform an antilock braking control in which a brake hydraulic pressure applied to wheel brakes is reduced under the condition that a slip-related amount has reached a pressure reduction threshold value; and a turning judging module configured to judge whether a vehicle is turning based on a steering angle, wherein, when the antilock braking control is performed and in the case that the turning judging module judges that the vehicle is turning, the antilock braking controlling module performs a turning pressure reduction control so as to: change the pressure reduction threshold values to be more easily reached by the slip-related amount than at the time of straight running; and change the pressure reduction amounts to be larger than that at the time of straight running.

A method of controlling operation of a vehicle is disclosed, wherein the vehicle comprises an auxiliary braking system and a number of wheel axles each comprising wheels and wheel brakes controllable to brake the wheels, and wherein one or more of the number of wheel axles is a liftable wheel axle. The method comprises the step of controlling at least one of the one or more liftable wheel axles from a lifted position to a lowered position if the at least one liftable wheel axle is in the lifted position and a ratio between an estimated braking capacity of the auxiliary braking system and a current or impending braking need of the vehicle is below a first threshold ratio.

A motorcycle braking arrangement comprising a brake lever (and/or brake pedal) defining a grasping or stepping surface, respectively, whereby a rider is able to apply pressure in order to produce a first analogue signal, a force-sensitive resistor (FSR) mounted on and/or in the surface and configured to produce a second analogue signal. In this manner, pressure applied to the grasping surface results in simultaneous production of the first and second signals, whereby a controller is configured to electronically correlate the second signal with the first. The arrangement also includes at least one servomechanism, which is arranged in signal communication with the controller and is configured to actuate a brake of the motorcycle according to the correlation between the first and second signals.

A one-side brake control system and method perform distribution of torques between front and rear wheels. The one-side brake control system includes a target steering angle input unit to which a target steering angle of a driver or a controller of an autonomous vehicle is input when a steering system fails, an integrated Electronic Control Unit (ECU) configured to calculate a target moment of the vehicle according to the target steering angle input through the target steering angle input unit and calculate brake torques of a one-side front wheel and a one-side rear wheel of the vehicle based on the target moment, and a braking ECU configured to control one or more braking actuators of the one-side front wheel and the one-side rear wheel of the vehicle according to the brake torque of the front wheel and the rear wheel transmitted from the integrated ECU to perform one-side brake.

A method controls a brake system of a vehicle combination. The switching valve in the second setting (anti-jackknifing braking function active) outputs a reservoir pressure into a trailer pressure line to actuate the trailer service brakes dependent on the anti-jackknifing braking demand. When service braking demand and anti-jackknifing braking demand are simultaneously present, an anti-jackknifing and a service braking ratio value are determined, a switchover criterion is checked dependent on the ratio values. The criterion is satisfied if the service braking ratio value exceeds a specified fraction of the anti-jackknifing braking ratio value when the anti-jackknifing braking function is active and falls below the specified fraction when the anti-jackknifing braking function is inactive; and, if the criterion is satisfied, the switching valve is switched over to activate the anti-jackknifing braking function and implement the anti-jackknifing braking demand, or to deactivate the anti-jackknifing braking function and implement the service braking demand.

An over actuated system capable of controlling wheel parameters, such as speed (e.g., by torque and braking), steering angles, caster angles, camber angles, and toe angles, of wheels in an associated vehicle. The system may determine the associated vehicle is in a rollover state and adjust wheel parameters to prevent vehicle rollover. Additionally, the system may determine a driving state and dynamically adjust wheel parameters to optimize driving, including, for example, cornering and parking. Such a system may also dynamically detect wheel misalignment and provide alignment and/or corrective driving solutions. Further, by utilizing degenerate solutions for driving, the system may also estimate tire-surface parameterization data for various road surfaces and make such estimates available for other vehicles via a network.
