Abstract: A brake control system for a motor vehicle having a plurality of wheels, brakes for applying a braking effort to one or more of the wheels, and a movement sensor for detecting movement of the vehicle. The system comprises a brake actuator for actuating the brakes to supply a braking effort and a brake controller for controlling the brake actuator. The brake controller is configured to determine an acceleration of the vehicle based on movement detected by the movement sensor and to ensure that the brake actuator supplies a braking effort if the determined acceleration exceeds a set acceleration limit.

Abstract: In consideration of an amplification effect of a braking force at the time of brake operation, upper-limits (α, β) of a brake operation force (Brk) with which the execution of free-run coasting and neutral coasting is started may be different, on the basis of whether or not a brake booster can be filled with a negative pressure. Therefore, while the braking force at the time of brake operation is secured, the range of the brake operation force (Brk) with which coasting is executed can be enlarged, and an improvement in fuel economy can be made.

Abstract: A method for vehicle control comprises determining a braking capability of a braking system of a vehicle, and modifying application of at least one control parameter by a control system of the vehicle based on the determined braking capability. Braking capability may be determined by activating the braking system of the vehicle to apply a braking force on the vehicle, and concurrently, applying a level of tractive effort of the vehicle that is sufficient to overcome the braking force. The braking capability is determined based on the level of tractive effort.

Abstract: A system for managing braking torque in a machine uses a first braking system, a second braking system that is independent of the first braking system and a controller that monitors activity in both braking systems. The controller selectively reduces torque in the first braking system as torque in the second braking system increases to limit undesired effects of possible over-braking

Abstract: A global positioning signal based learned control event prediction method and apparatus includes a learning auxiliary module connected to a communication bus of a vehicle. The arrangement stores events and event locations using global positioning signals for a vehicle traveling along a path. When the vehicle travels the same path a second time, the detected events and event locations are determined. When the events match at the same event locations, a predictive action is determined for a future occurrence of the vehicle approaching the event location. Thus, as the vehicle approaches the event location, the predictive action, for example pre-filling of the vehicle brakes or pre-tensioning of the seat belts occurs.

Abstract: An electrically driven vehicle equipped with electric motors (1, 4) for driving or braking drive wheels (3, 6), and an electric motor controller (33) for controlling the electric motors includes: wheel speed detectors (9 to 12) for detecting the wheel speed of the drive wheels and that of idler wheels (7, 8); computing means (22 to 28, 35 to 38) for computing the slip ratio of the drive wheels based on the wheel speed of the drive wheels and that of the idler wheels; and a determiner (29) for determining that the drive wheels are slipping if the slip ratio exceeds a slip ratio determination value. If the wheel speed of the idler wheels is lower than set speeds Va2, Vb2, then the determiner (29) changes the slip ratio determination value to a value having as the same sign as, and a larger absolute value than, the values λa2, λb2 used when the wheel speed of the idler wheels is higher than the set speeds Va2, Vb2. This structure shortens acceleration time during acceleration traveling and reduces braking distance during deceleration traveling while inhibiting vibrations of the electrically driven vehicle.
