Setting braking pressure for vehicle involves releasing first braking pressure, applying second pressure for long-term parking, applying first pressure for start-up, removing to drive off

Abstract: The method involves maintaining the required braking pressure to ensure that a vehicle is not moved by an external force by determining the difference between a drive torque and an external moment on the vehicle and generating a first braking pressure by a first brake(3) so that a braking force is exerted on at least one vehicle wheel if the drive torque is less than the external moment. The first braking pressure is released and a second braking pressure simultaneously produced by a second brake(4) if a long-term parking condition is fulfilled. The second braking pressure is released and the first braking pressure is applied simultaneously if a start-up condition is fulfilled and the first braking pressure is released if a driving off condition is fulfilled.

Electric vehicle regenerative braking system

Abstract: A method and system for braking a vehicle are disclosed. The vehicle has at least one of an electronic stability control system and an antilock brake system. The vehicle may also include a regenerative brake adapted to apply a regenerative braking torque to slow the vehicle. The vehicle may further include a pressure sensor adapted to sense pressure in a hydraulic brake line. The pressure sensor may be a component of the at least one of the electronic stability control system and the antilock brake system. The vehicle may also include a controller adapted to control the regenerative braking torque of the regenerative brake based on at least the sensed pressure.

Electrically controlled vehicle brake system having means for controlling braking based on detected actual braking effect and determined target braking effect

Abstract: An electrically controlled brake system including a brake operating member, a first detector for detecting an operating amount of the brake operating member, a braking device braking a wheel of a vehicle, a second detector for detecting an actual braking effect provided by the braking device, and a controller for controlling the braking device. The second detector detects the actual braking effect in the form of a positive value when the vehicle is running in one of a forward and a backward direction, and in the form of a negative value when the vehicle is running in the other of the forward and backward directions. The controller determines a positive value as a target braking effect based on the detected operating amount of the brake operating member, and controls the braking device such that an absolute value of the detected actual braking effect coincides with the positive value of the determined target braking effect.

Device for detecting and monitoring emergency braking effect of railway locomotive

Abstract: The device has a braking effect detection stage (2) for detecting deceleration in the vehicle's longitudinal direction and a braking effect monitoring stage (6), which outputs an "inadequate braking" warning (FBV) when the deceleration difference signal between measured actual and demanded deceleration values exceeds a threshold value. An error handling stage (7) detects an emergency braking failure when an "emergency braking" signal (MNB) and an "inadequate braking" signal are present and delivers control commands to several braking systems on the vehicle in order to achieve maximum residual braking.

Vehicle dynamics control system

Abstract: In a vehicle dynamics control (VDC) system for a four-wheel-drive vehicle employing a brake control system regulating braking forces applied to road wheels independently of each other and a differential mechanism controlling a differential motion between front and rear wheel axles, a VDC controller controls a braking force of each road wheel depending on whether the vehicle is in oversteering or understeering. The VDC controller includes a braking-force compensation section that compensates for a braking force of at least one of a first wheel, which is subjected to vehicle dynamics control, and a second wheel to which a transferred braking force is transferred from the first wheel through the differential mechanism, to reduce a braking force of the second wheel and to prevent the braking force of the second wheel from exceeding a lateral grip limit of the second wheel during the vehicle dynamics control.
