20080215223 | BRAKING CONTROL DEVICE OF VEHICLE - In a braking control device which performs braking control to stabilize vehicle behavior, a driving state switching unit changes a driving state of a vehicle. A slip condition detecting unit detects a slip condition of the vehicle. A braking control permission judging unit determines whether actuation of braking control is permitted. The braking control permission judging unit is arranged so that, if the driving state is changed to a direct-connection four-wheel-drive condition by the driving state switching unit, the braking control permission judging unit permits actuation of braking control when the slip condition detected by the slip condition detecting unit exceeds a predetermined slip condition. | 09-04-2008 |
20080228368 | Method for Controlling a Brake System of a Motor Vehicle with All-Wheel Drive - A method of controlling a brake system of an all-wheel driven motor vehicle, which includes an electro-regenerative brake and a number of friction brakes such that a total brake torque comprises brake torque components of the friction brakes and of the electro-regenerative brake; the brake torque of the electro-regenerative brake is subdivided between the front axle and rear axle in predetermined ratios. The brake torque generated by the electro-regenerative brake is limited to such an extent that the brake slip of one axle of the motor vehicle does not exceed a selectable maximum value. | 09-18-2008 |
20090048754 | Determining the vehicle linear velocity in vehicles having all-wheel drive - A method for determining the vehicle linear velocity of a vehicle having all-wheel drive, and which is equipped with a central lock and a vehicle controller to implement an ABS or ASR control. The vehicle linear velocity is able to be determined if a braking-pressure difference is adjusted at the wheels of an axle, and, in the case of an ABS control, the vehicle linear velocity is determined from the rotational speed of the wheel having the higher speed, and from the slip of this wheel, and, in the case of an ASR control, it is determined from the rotational speed of the wheel having the lower speed, and from the slip of this wheel. | 02-19-2009 |
20100030445 | BRAKE FORCE MAINTAIN CONTROL DEVICE - A brake force maintain control device for a vehicle determines whether the vehicle is in a rapidly-pressed state. The rapidly-pressed state is a state in which the brake pedal of the vehicle has been further pressed rapidly. While the vehicle is in the rapidly-pressed state, the brake force maintain control device allows the brake force maintain control to start if a condition for starting the brake force maintain control is satisfied. Therefore, it is possible to prevent the brake force maintain control from being needlessly executed even though the driver does not have an intention of executing it. | 02-04-2010 |
20100049416 | BRAKE CONTROL DEVICE FOR ELECTRIC VEHICLE - A brake control device for an electric vehicle includes an instruction controller, a pattern generator, and comparators. The instruction controller generates an instruction signal for instructing a motor about electric brake force. The pattern generator generates a first pattern signal for changing over electric brake force to machine brake force and a second pattern signal obtained by shifting the first pattern signal by a predetermined frequency. One of the comparators outputs an electric-brake force pattern, which is the smaller one of the instruction signal and the first pattern signal. The other of the comparators outputs a notification signal when the second pattern signal becomes equal to or smaller than the instruction signal. | 02-25-2010 |
20130261924 | METHOD FOR CONTROLLING AN ANTISLIP-REGULATED FRICTION BRAKE SYSTEM OF A RAIL VEHICLE - A method for controlling an antislip-regulated friction brake system of a rail vehicle or rail vehicle train having a number of braked axles which subjects at least two selected axles to a braking pressure exceeding the braking pressure required for braking; measures at least one variable representing the maximum transmittable frictional force in each case between the wheels of the selected axles and the rail; prepares a list associating the selected axles with the respectively transmittable brake friction force; identifies at least one brake-slipping axle from the selected axles in which a brake slip exceeding a predetermined extent occurs; calculates lost braking work; identifies from the list at least one axle in which brake-slipping does not occur or occurs to a permissible extent; and applies the brakes on at least one axle. | 10-03-2013 |
20140095046 | VEHICLE BRAKE DEVICE - A vehicle brake device comprises a hydraulic brake device, a regeneration brake device and a brake control device. The brake control device further includes a final value calculating device for calculating the target braking force FR at the time when an ABS control period ended and the cooperative control device restarted the operation to be as a regeneration allowing braking force FH, when the anti-lock brake control device has operated for the ABS control period within one braking operation period where the brake operating member is continuously operated and a regeneration allowing device operable after the ABS control period ended within the one braking operation period and after the cooperative control device restarted the operation and allowing the generation of the regeneration braking force FE only when the target braking force is less than a value of the regeneration allowing braking force FH. | 04-03-2014 |
