When engine braking is large on the basis of the accelerator pedal position signal, the clutch connection signal, and the power transmission signal, the vehicle braking force control device changes the predetermined threshold value to an offset threshold value that makes it harder to perform the antilock brake control than at the normal time.

    Abstract: Provided is a vehicle motion control system that comprises a plurality of vehicle behavior control units that are controlled in a mutually coordinated manner, and is configured to operate as designed even when one of the vehicle motion control units should fail. If a RTC-ECU (61) has ceased a control action thereof owing to a failure thereof, a VSA-ECU (31) retains the last received coordination control signal from the RTC-ECU in EEPROM (37) so that the VSA-ECU (31) is enabled to continue the coordinated control according to the retained coordination control signal. At the same time, the VSA-ECU (31) transmits the coordination control signal retained in the EEPROM onto a CAN so that the transmitted coordination control signal may be used by other ECUS of other vehicle behavior control units such as an ATTS-ECU (41) and a STG-ECU (51). In this manner, the behavior of the vehicle may be optimized by the coordination control of the VSA unit and other vehicle behavior control units.

  • Publication number: 20140129088
    Abstract: The invention relates to a method for controlling the driving dynamics of a vehicle, especially of a single-track or dual-track and vehicle. The driving dynamics of the vehicle are controlled by way of brake and/or engine intervention, notably depending on a change of the movement of the vehicle in the three-dimensional space and relative to the earth coordinate system and depending on the effective direction of gravity or the earth's gravitational pull. According to said method, the attitude or orientation and the position of the vehicle in three-dimensional space and relative to the earth coordinate system is determined by means of a satellite navigation system (GNSS) which comprises a receiver, mounted on/in the vehicle, having at least three antennas for reception of satellite navigation signals and an inertial measuring system (INS), mounted on/in the vehicle, for measuring all changes in the movement, position and/or attitude of the vehicle.

    Abstract: A vehicle includes an internal combustion engine, brake actuators configured to slow the vehicle in response to braking commands, and a transmission. The transmission includes a plurality of gear sets each having a plurality of nodes, an input member that is continuously connected to the engine and to a node of one of the gear sets, a reverse clutch, a binary clutch assembly, and a controller. The binary clutch assembly is connected at least to the same gear set as the input member, and is applied with the reverse clutch when entering a reverse gear state. The controller executes a method to transmit the braking commands to the brake actuators in response to a requested garage shift into a reverse gear state when the vehicle is rolling above a calibrated speed threshold, and thereby slows the vehicle until a calibrated target slip is achieved across the binary clutch assembly.
