Abstract: The invention relates to a brake system which comprises an actuating device (26), especially a brake pedal (30), and a control/regulation device (22). Said control/regulation device (22) controls at least one electromotive drive device (7a, 7b, 8) in response to the movement and/or position of the actuating device (26). The drive device adjusts a piston (1, 1a, 1b) of a piston/cylinder system via a non-hydraulic transmission device, thereby adjusting a pressure in the working compartment (4?, 4?a, 4b?) of the cylinder. Said working compartment is connected to a wheel brake (15, 17) via a pressure conduit (13, 13a). A valve (14, 14a, 15, 15a, 14?, 14a?) is interposed between the brake cylinder of the wheel brake and the working compartment of the piston/cylinder system. The control/regulation device opens the valve for pressure suppression or pressure build-up in the brake cylinder and closes it in order to maintain the pressure in the brake cylinder.

Abstract: The invention relates to a vehicle braking system, the slip of which can be regulated electronically, for which, in the event of an automatic braking process, the activation of the foot pedal by the driver, does not result in a significant actuating path.

To achieve this, a valve unit is controlled in such a way that a pressure medium flows from the wheel brake to the pressure medium reservoir and the drive motor of the pressure generator is controlled in parallel.

Abstract: A brake controller function to optimally brake a wheel of a vehicle in motion, such as an aircraft. The brake pressure control self regulates by means of applying brake pressure in accordance with vehicle acceleration information and the change in acceleration over time in the horizontal plane.

Abstract: A stepwise brake control is automatically performed when TTC obtained according to a relative distance and a relative speed between a vehicle and an object is lower than a predetermined value. For example, a brake pattern is modified according to the weight of a cargo and passengers. Alternatively, a driver selects a brake pattern of different (rapid or slow) speed reduction according to the type or weight of the passengers and cargo. Furthermore, the driver's psychology is acquired according to the alarm distance between vehicles set by the driver and an optimal brake pattern is selected according to this. Alternatively, an operation state of the vehicle by the driver is detected and if the detection result does not satisfy a predetermined condition, the set value of the TTC is increased. For example, the predetermined condition indicates the normal state of the driving by the driver.
