Abstract:
The invention relates to a method for stabilising a vehicle combination including a towing vehicle and at least one trailer vehicle, said method comprising at least the following steps: determining (St1) rotational speeds (n_HA) of wheels at least of a driven axle of the towing vehicle, and a vehicle velocity (v) of the towing vehicle ; checking (St2) at least one first criterion (K1) of whether a braking wheel-slip occurs on the driven axle of the towing vehicle, without actuating a wheel brake of the driven axle; and, if the first criterion (K1) is fulfilled, actuating (St5) the wheel brakes of the trailer vehicle.
Abstract:
A control apparatus for a vehicle that includes an engine (15), a drive wheel (12), a non-drive wheel (11), a stepped automatic transmission (17) a coupling device (16) and a braking device (20), the control apparatus includes an ECU (30). The ECU is configured to: execute a target idle speed control; set an upper limit value of the target idle speed when a specified low µ road control condistion is establisued whiled the brake acts on the vehicle such that the upper limit value when the transmission is in first gear is smaller than the upper limit value when the transmission is in second gear; and set a change rate of the upper limit value such that the change rate when the transmission shifts from first to second gear is smaller than the change rate when the transmission shifts from second to first gear.
Abstract:
It is an object of the present invention to provide a vehicle braking force control device that can cause a brake device to perform braking as envisioned by a driver even in a situation where a large braking force resulting from engine braking is acting. A vehicle braking force control device that is installed in a vehicle and which, at a normal time, performs antilock brake control at a time when the slip ratio of a wheel has become equal to or greater than a predetermined threshold 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, and at a time when the vehicle braking force control device has determined that the action of 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 method of braking a vehicle (15) which includes ground engaging wheels (16-19), and a braking system (28) with ABS capability and including an operator actuated brake control (31), the ABS becoming operative in response to the operator actuating the brake control (31), and upon the braking system (28) sensing the slippage or impending slippage of at least one of the ground wheels (16-19) relative to the ground, to vary the braking force applied to the at least one of the wheels (16-19) between, in alternative periods, an applied state in which the braking force is applied, and a released state in which the braking force is released, and characterised in that the method includes applying torque to assist acceleration of the wheel (16-19) at least during periods in which the braking force is released by the ABS.
Abstract:
The invention relates to a method for influencing a torque conveyed by a driving motor of a motor vehicle. According to the inventive method, load alternation that occurs during cornering of the motor vehicle is detected. A minimum value of an intervening variable which influences the conveyed torque is detected when load alternation occurs during cornering and the driving motor is impinged upon with the minimum value of the intervening variable for a given time. The aim of the invention is to improve the load alternation behaviour of the motor vehicle during cornering and to improve performance of the motor vehicle in overrun. The detected minimum value of the intervening variable and/or the time is/are corrected according to the friction coefficient of a roadway and/or according to a deceleration of the motor vehicle, whereby the motor vehicle drives on said roadway.
