Abstract: A vehicle braking force control device which, at a normal time, performs antilock brake control when the slip ratio of a wheel has become equal to or greater than a predetermined threshold. The control device acquires from the engine control unit an accelerator pedal position signal corresponding to an accelerator pedal position, a clutch connection signal corresponding to a state of connection of a clutch, and a power transmission signal corresponding to a state of power transmission of a transmission. 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: A vehicle has a drive unit driving wheels of a vehicle axle and braking the vehicle via a drive train in drag mode, an electronic control unit measuring actual wheel rotational speeds of the wheels, and a brake booster for reducing the actuating force at the brake pedal. A test unit is assigned to the electronic control unit and performs a plausibility check of the actual wheel rotational speeds in drag mode, wherein the test unit activates during the plausibility check the vehicle brake of one of the vehicle wheels and detects, from the rotational speed behavior of the wheel with a non-activated vehicle brake, whether the measured actual wheel rotational speeds correlate with the actual vehicle speed. A brake booster can be actuated by the test unit during the plausibility check in order to activate the vehicle brake.

Abstract: A system is provided for controlling the inertia of a vehicle's powertrain during sudden braking events. Torque generated by rapid deceleration of the vehicle's drive wheels during braking is prevented from being transmitted through the vehicle's driveline by a clutch which disengages the drive wheels from high effective inertia components in the driveline. The clutch is actuated by a signal produced by any of several sensors on the vehicle which sense a sudden braking event. Driveline speed is adjusted to match drive wheel speed before the clutch is deactivated to reengage driveline with the drive wheels.

Abstract: An exemplary method is described for influencing the moment delivered by a vehicle drive of a vehicle. In this method a change in load which occurs during cornering of the vehicle is detected, upon detection a minimum value of an intervention quantity which influences the torque delivered is determined and the vehicle drive is acted upon by the minimum value of the intervention quantity for a selectable period of time. To achieve an improvement in the change in load performance of a vehicle in cornering and an improvement in the driving performance of the vehicle in coasting operation, the minimum value determined for the intervention quantity and/or the period of time is corrected as a function of the coefficient of friction of the road surface on which the vehicle is traveling and/or as a function of a deceleration of the vehicle.

Abstract: Provided is a braking force control apparatus for vehicles capable of performing appropriate vehicle braking even in a road-contactless state of a wheel. The braking force control apparatus is adapted to a four-wheel drive vehicle having a center differential for distributing and transmitting driving force to the front wheels and rear wheels and a braking system capable of exerting braking force on each of the front and rear wheels, based on voluntary switching between braking according to driver's brake-pedal actuation and forced braking independent of the brake-pedal actuation. It is determined whether the vehicle is in an engine brake state and it is then determined whether at least one of the wheels is in the road-contactless state. When an engine brake determining device determines that the vehicle is in the engine brake state and when a road-contactless state determining device determines that at least one of the wheels is in the road-contactless state, the braking force based on the forced braking is exerted on the wheels other than the at least one wheel while the braking force based on the driver's brake-pedal actuation is permitted to be exerted on the at least one wheel.
