Towed vehicles can be extremely heavy. Accordingly, it is too much of a burden to the braking system of a towing vehicle to not have brakes on the towed vehicle. Controlling the brakes of the towed vehicle must be accurately applied otherwise very dangerous conditions can be created. A method of controlling braking of a towed vehicle is, therefore, needed. The method comprises receiving speed signals based on speed of a towing vehicle, or a towed vehicle, or both said towing vehicle and said towed vehicle, receiving pressure signals based on pressure of a hydraulic brake system of the towing vehicle, and generating a brake output signal based on the speed signals and the pressure signals.

A method for adjusting brake pressures on pneumatically operated wheel brakes of a motor vehicle includes setting, in a normal braking mode, a brake pressure depending on a driver brake request determined by the driver of the motor vehicle and a control unit, during reception of an external brake request which is independent of the driver brake request, in a pressure control mode, sets a resulting brake pressure at the respective wheel brakes taking into account the external brake request and the driver brake request. The method further includes terminating, after revocation of the external brake request, the pressure control mode depending on a comparison of a value representing the driver brake request and entered into the control unit with a predefined threshold value.

The braking device for vehicles comprises a reduction amount setting part 62 for setting the amount by which to reduce the revolution of a pump motor M during maintenance or reduction of controllable differential pressure so that said reduction amount decreases as the probability increases of needing to discharge the brake fluid by means of pumps 37, 47 during a period from when a brake ECU 60 begins reducing the revolution Nd until the lapse of prescribed time.

Provided is a work vehicle having a compact braking device. The work vehicle includes a drive shaft part to which power generated by a power source is transmitted and which transmits the power to drive wheels via a differential device, and a drive shaft braking mechanism which generates a braking force on the drive shaft part when a brake pedal is depressed.

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.

A driver alert arrangement for a motor vehicle includes a sensor detecting that the motor vehicle is in motion and transmitting a signal indicative of whether the motor vehicle is in motion. A driver monitoring camera captures images of a human driver of the motor vehicle. An electronic processor is communicatively coupled to the sensor, the driver monitoring camera, and to a user interface. The electronic processor receives the signal from the sensor, receives the images captured by the driver monitoring camera, determines from the images where the driver is looking, and alerts the driver via the user interface that the motor vehicle is in motion. The alerting is dependent upon the signal and where the driver is looking.

The invention is directed to an inertial sensor attachment structure including: a floating bracket which is fixed to a vehicle body frame via a vibration absorbing member; an inertial sensor attached to a first attachment surface of the floating bracket; and an ABS unit attached to a second attachment surface of the floating bracket.

A fuel cell system mounted on a vehicle includes a drive motor generating a driving force and regenerative power; an auxiliary machine consuming the regenerative power; and a controller. The controller determines that the vehicle is in a first state when the vehicle has a negative vehicle speed, a move forward request is given to the vehicle and an accelerator pedal is depressed or when the vehicle has a positive vehicle speed, the move backward request is given to the vehicle and the accelerator pedal is depressed. When a predetermined first condition including a condition that the vehicle is in the first state is satisfied, the controller performs an auxiliary machine consumption process that causes the auxiliary machine to consume the regenerative power that includes a required power for the drive motor calculated by using a depression amount of the accelerator pedal.

A brake operating device in which an operation of a brake pedal can be detected easily by a simple structure is provided. The brake operating device 1 comprises: a pusher 19, 20 connected to a brake pedal 2; a hydraulic system 5 in which fluid is held between the pusher 19, 20 and a pushing element 27 to transmit a thrust force of the pusher 19, 20 to the pushing element 27; a first elastic mechanism 23a, 23b that establishes an elastic force to isolate the pusher 19, 20 away from the pushing element 27; a cylinder 18 holding the pusher 19, 20 while restricting a withdrawal limit of the pusher 19, 20 in a direction away from the pushing element 27; and a second elastic mechanism 37 that is arranged at a position to push the cylinder 18, and that establishes an elastic force against the elastic force in the direction to isolate the pusher 19, 20 away from the pushing element 27.

A method for determining the overall-deceleration values is attainable by actuation of wheel brakes, of a utility vehicle or of a vehicle combination with several axles. For the purpose of implementing a deceleration request in the course of partial brake applications, a braking-force distribution with braking forces distributed unequally to brake units with the wheel brakes of one or more axles is undertaken. In each instance one of the brake units is selected and a larger braking force is imposed via this selected brake unit than via the other brake units. A current deceleration of the utility vehicle or of the vehicle combination is measured or ascertained and is assigned as partial-deceleration value to the respectively selected brake unit and stored and the attainable overall-deceleration values are determined as the sum of the partial-deceleration values of all the brake units.
