Abstract:
An object of the invention is to provide a traction control device capable of preventing a reduction in acceleration. A traction control device of the invention includes a braking mechanism controller (84) that controls a braking mechanism. The braking mechanism controller (84) includes: a target brake torque calculating section (845A) that calculates a target brake torque to each of wheels based on the rotation speed of the wheel and an estimated vehicle speed; a target brake torque determining section (845B) that determines whether or not the target brake torque reaches or exceeds a per-stored threshold; a reference wheel determining section (845C) that selects a reference wheel used as a reference for controlling the braking mechanism based on the target brake torque to each of the wheels; and a target brake torque reducing section (845D) that reduces the target brake torque in accordance with a difference between the target brake torque to the reference wheel and the threshold when the target brake torque to one of the wheels reaches or exceeds the threshold.
Abstract:
The invention relates to a method for distributing brake torque between at least a first and a second brake system of a motor vehicle comprising at least two wheel axles and four wheels with tires, in which the first brake system acts on at least one wheel axle and in which the second brake system acts on at least one driven wheel axle and in which the distribution of brake torque between the first and the second brake system takes account of the wear of the tires and the constituent components of the brake systems.

The invention relates to an electronic retarder control (ECU) in a motor vehicle comprising a retarder. According to the invention, the electronic retarder control (ECU) is located on the exterior of the retarder housing.
Abstract:
In motor vehicles, vibrations that are produced in the vehicle clutch occur in the drive train during the slip phase of a clutch. These vibrations arise when periodic torques are produced by a slipping clutch. The periodic torques are located in the natural frequency range of the drive train that is dynamically separated by the clutch. In the drive train, torsional vibrations of this type are converted into longitudinal vibrations by the driving wheels of the vehicle and are uncomfortably felt by the vehicle occupants. The aim of the invention is to create a method and device with which these disturbing vibrations are reduced at least in the height of their amplitude. To this end, the invention provides that the disturbing oscillations are ascertained by using a controlling and regulating device (24) and appropriate sensors (34, 36, 41), and when predefined limit values are exceeded, at least one device (7, 11, 15, 23, 29, 30) is actuated, by which the components of the vehicle are acted upon in order to dampen or compensate for the disturbing vibrations.
Abstract:
A vehicle braking control system is provided that controls at least three braking devices including a regenerative braking device (9R and 9L), a hydraulic braking device (5R and 5L),and an electric braking device (7R and 7L). The vehicle braking control system basically comprises a braking mode selecting section (15 and S4), a required braking force determining section (S3),and a target braking force setting section (SS-S15). The braking mode selecting section (15 and S4) sets one of a plurality of braking modes having a different braking control priority for each of the target braking forces. The required braking force determining section (S3) determines a required braking force for an entire vehicle (1). The target braking force setting section (S5-S15) sets each of the target braking forces based on the braking control priority of the selected braking mode to produce the required braking force for the entire vehicle (1). Preferably, the braking mode selecting section (15 and S4) sets at least an electric power maintenance priority mode and a braking response priority mode.
Abstract:
Ein Verfahren zur Steuerung der Bremsanlage eines Fahrzeugs mit einer steuerbaren Betriebsbremse und einer steuerbaren Dauerbremse, wobei die Betriebs- und Dauerbremse aufeinander abgestimmt angesteuert werden, ist dadurch gekennzeichnet, daß die Dauerbremse bei jedem Bremsvorgang aktiviert wird und abhängig vom Bremswunsch des Fahrers sowie von Fahrzustandsgrößen und/oder Fahrbahnzustandsgrößen und/oder Betriebszuständen des Fahrzeugs angesteuert wird (integrierte Betätigung der Dauerbremse).
