Controlling vehicle brakes

An apparatus for controlling braking of a vehicle having a plurality of brake-packs. The apparatus includes a controller configured to receive a first plurality of input values having a first scatter value; calculate an adjustment factor for each brake-pack based on the received first plurality of input values; output a control signal to cause each brake-pack of the plurality of brake-packs to be applied at a pressure based on the adjustment factor calculated for that brake-pack; and receive a second plurality of input values having a second scatter value. Each input value relates to a different one of the plurality of brake-packs. The adjustment factors are calculated such that the second scatter value is less than or equal to the first scatter value.

A control device is provided with: a moving distance estimation unit that calculates an estimated value of a vehicle moving distance on the basis of a pulse signal inputted from a wheel speed sensor and a wheel dynamic load radius stored in a storage unit; a moving distance deriving unit that derives the calculated value of the vehicle moving distance on the basis of information acquired by monitoring systems; a vehicle stop position setting unit that sets a target vehicle stop position on the basis of the information acquired by the monitoring systems; a correction unit that corrects the target vehicle stop position on the basis of the calculated value of the moving distance and the estimated value of the moving distance; and a brake control unit that assists vehicle stoppage so as to stop the vehicle when it is determined that the vehicle has reached the target vehicle stop position on the basis of the vehicle moving distance calculated from a wheel rotation amount and the target vehicle stop position.

DRIVING SUPPORT SYSTEM

A driving support system installed on a vehicle includes a sensor detecting a vehicle state, a braking device, and a control device. The control device determines, based on the vehicle state, whether or not a first condition suggesting roll back of the vehicle is satisfied, and whether or not a second condition more strongly suggesting the roll back of the vehicle than the first condition is satisfied after the first condition is satisfied. When the second condition is satisfied after the first condition is satisfied, the control device executes roll back suppression control that controls the braking device to generate a braking force such that the vehicle stops. During a period from when the first condition is satisfied to when the second condition is satisfied, the control device executes precharge control that decreases play in the braking device without starting the roll back suppression control.

BRAKING CONTROL APPARATUS

A braking control apparatus to be installed an electric vehicle includes an acceleration and deceleration operation member, a controller, and a recognizer. The acceleration and deceleration operation member receives an acceleration request in accordance with an operation amount in a first direction from a neutral position, and receive a deceleration request in accordance with an operation amount in a second direction from the neutral position. The controller controls an amount of power regenerated by a rotary electric machine driven by wheels in accordance with the operation amount in the second direction. The recognizer recognizes a preceding vehicle traveling ahead of the electric vehicle. Upon detection of the preceding vehicle at a relative distance from the electric vehicle that is equal to or less than a threshold, the controller performs braking suppression control to decrease the amount of power regenerated in accordance with the operation amount in the second direction.

Electric braking device for vehicle

This electric braking device for a vehicle imparts to the wheels of the vehicle a braking torque in accordance with the output of an electric motor. A vehicle body-side electronic control unit calculates a command value for the output of the electric motor on the basis of the amount of operation performed on a braking operation member. A wheel-side electronic control unit adjusts the output of the electric motor on the basis of the command value. The vehicle body-side electronic control unit calculates the vehicle body speed on the basis of the wheel speed. The wheel-side electronic control unit adjusts the output of the electric motor so as to prevent an increase in slippage of the wheels on the basis of the vehicle body speed and the wheel speed.

A method monitors a condition of a mechanical brake of an aircraft. In the method, a temperature of the mechanical brake is measured at at least one point in time during a landing operation after commencement of a mechanical braking operation. The measured temperature is compared with a standard temperature determined for the mechanical brake, at the at least one point in time during the landing operation after commencement of the mechanical braking operation. A state of wear of the mechanical brake is then identified on the basis of the measured temperature having exceeded the standard temperature beyond a predefined measure.

BRAKING DEVICE FOR VEHICLES

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.

Operating Method for an Automatic Transmission of a Motor Vehicle

The invention relates to an operating method for an automatic transmission, particularly for an automatic variable-speed transmission and/or dual-clutch transmission, for a motor vehicle. The automatic transmission can be operated in a cost-effective manner, particularly with reduced component wear and increased service life, and/or the driving comfort of the vehicle can be improved such that when lifting of at least one driven vehicle wheel off the roadway during braking is detected by the operating method, then for the length of said braking process, in the event of an incomplete gear change into a gear of the transmission, the engagement of a gear is prevented and/or the beginning of a gear change into a gear of the transmission is prevented.
