Controller, vehicle body behavior control system, motorcycle, and control method
The present invention obtains a controller capable of improving safety of a motorcycle. The controller that controls vehicle body behavior of the motorcycle includes: an acquisition section that acquires trigger information generated in accordance with peripheral environment of the motorcycle; and an execution section that initiates a control mode making the motorcycle execute an automatic brake operation in accordance with the trigger information acquired by the acquisition section and makes the motorcycle generate a braking force. The acquisition section further acquires seat load information that is information of a load received by a seat of the motorcycle, and the execution section changes the automatic brake operation, which is executed in the control mode, in accordance with the seat load information acquired by the acquisition section.
LOAD MONITORING, BRAKING CONTROL, AND HEIGHT MANAGEMENT
Systems and methods for load monitoring and/or braking control. The load monitoring may include calculating a weight on one or more axles of a vehicle or a trailer using cross-flow pressure information indicative of an air pressure within a cross-flow passage between first and second leveling valves of first and second pneumatic circuits configured to adjust independently heights on first and second sides, respectively, of the vehicle or the trailer. The braking control may include (i) using the cross-flow pressure and speed and/or acceleration information indicative of a speed and/or acceleration of the vehicle and/or the trailer to calculate first and second brake application levels and (ii) applying the calculated first and second brake application levels to first and second brakes on the first and second sides, respectively, of the vehicle or the trailer.
VEHICLE WITH VALVE THAT ADJUSTS OUTPUT BRAKE PRESSURE ACCORDING TO A PLURALITY OF PRESSURE CURVES
A vehicle includes: a brake pedal to produce vehicle brake pressure; a trailer brake valve to output a variable trailer brake pressure to a trailer brake of a trailer, the trailer brake valve configured to output the variable trailer brake pressure as a function of the vehicle brake pressure; and an electronic control unit operably coupled to the trailer brake valve and configured to: output a first valve signal to the trailer brake valve to output the trailer brake pressure according to a first vehicle brake pressure curve; and output a second valve signal to the trailer brake valve to output the trailer brake pressure according to a second vehicle brake pressure curve responsively to determining a curve adjustment condition exists. The first vehicle brake pressure curve and/or the second vehicle brake pressure curve is not a single straight line curve.
Brake control apparatus for vehicle
Provided is a brake control apparatus configured to: set a target slip degree of each of three wheels other than an outer front wheel to a slip degree of the outer front wheel; perform feedback control so that an actual slip degree of each of the three wheels becomes close to the target slip degree; and decrease a feedback control amount of a wheel which is to be controlled to increase an anti-spin yaw moment when an understeer suppression condition is satisfied.

System and method for reducing aircraft brake wear
A system and method are provided for continuous monitoring and controlling of aircraft braking that can reduce brake wear and aircraft operating costs through the retention of carbon brake powder from the brakes or addition of carbon powder in a device mounted with respect to the brake disc stack. The use of carbon powder reduces brake wear by providing small particles between the brake discs, acting as a buffer between the brake discs when the brake stack is clamped together. Moreover, when carbon powder or small particles are used at application, such use reduces the roughness of the carbon surface and reduces the number of large particles from braking off the carbon surface, thereby reducing brake wear. Adaptive or selective braking may be used in conjunction with carbon powder to further reduce carbon brake wear.

BRAKE COMPLIANCE CALIBRATION WITH ELECTROHYDRAULIC BRAKES
An EH braking system including a brake valve operably connected to a brake and a brake pressure sensor. A calibration event for the EH braking system where the compliance calibration time is measured from when the brake valve is operated at full activation to when the brake pressure sensor senses the pressure starts to build in the brake circuit. The compliance calibration time is the time it takes to fill the compliance volume of the brake(s). The compliance calibrated fill time is used during a normal braking event wherein the brake valve will be operated to a full activation condition for duration of the compliance calibration time. After the calibrated fill time has elapsed, the brake valve will be operated at the desired operator command of the brake pedal. This results in quicker fill times of the brake and better brake system response.
SYSTEM AND METHOD PERTAINING TO BRAKING OF A VEHICLE COMBINATION WHICH COMPRISES A TRACTOR VEHICLE WITH A TOWED VEHICLE
A method pertaining to braking of a vehicle combination (100) which combination comprises a tractor vehicle (110) with a towed vehicle (112), where both are configured to be braked. The tractor vehicle (110) is provided with a first control unit (200) having a function for regulation of coupling force between the tractor vehicle (110) and the towed vehicle (112). Regulation of coupling force includes adaptation data and the towed vehicle bears an ID specification. The method includes the steps of: transferring the ID specification from the towed vehicle (112) to the tractor vehicle (110); during a braking process, registering adaptation data associated with the braking process together with the ID specification. Also a computer program product includes program code (P) for a computer (200; 205) for implementing the method. Also a system pertaining to braking of a vehicle combination (100) and to a vehicle combination (100) is equipped with the system.
BRAKING DEVICE FOR ELECTRIC AUTOMOBILE
In an electric automobile traveling by driving a rear wheel with an electric motor mounted on a vehicle body rear part, a load distributed to the rear wheel is larger than a load distributed to a front wheel by an amount corresponding to a weight of the electric motor. Therefore, it is desirable that a braking force distribution amount to the rear wheel be larger than that to the front wheel. Without providing a proportional pressure reducing valve changing a ratio of braking force distributed between the front and rear wheels, it is possible, by supplying a same brake fluid pressure from a master cylinder to front and rear wheel brake calipers and carrying out regenerative braking in the rear wheel, to make the braking force distribution amount to the rear wheel larger than that to the front wheel.
