Improved methods of controlling the stability of a vehicle are provided via the cooperative operation of vehicle stability control systems such as an Active Yaw Control system, Antilock Braking System, and Traction Control System. These methods use recognition of road surface information including the road friction coefficient (mu), wheel slippage, and yaw deviations. The methods then modify the settings of the active damping system and/or the distribution of drive torque, as necessary, to increase/reduce damping in the suspension and shift torque application at the wheels, thus preventing a significant shift of load in the vehicle and/or improving vehicle drivability and comfort. The adjustments of the active damping system or torque distribution temporarily override any characteristics that were pre-selected by the driver.

In order to enhance the accuracy of estimation of a vehicle's sideslip angle, a sideslip angle estimation apparatus calculates an angle between the direction of centrifugal force acting on the vehicle body during cornering and the lateral direction of the vehicle body based on accelerations exerted on the vehicle body and acting in two different directions. A sideslip angle between the longitudinal direction of the vehicle body and the direction of travel of the vehicle is calculated based on the estimated angle.

The invention relates to a method of adjusting an electronic stability program (ESP) for a motor vehicle. This method comprises various steps, including in particular: establishing the curve of the consumption values (Cesp) as a function of time, said curve being representative of the differences (dCM) of the measured yaw angles and the setpoint yaw angles (dCM=LM−LC) versus the measured triggering threshold values (St), modifying the nominal threshold values (Sv) by a percentage that is proportional to the consumption values (Cesp).
摘要:
A system, method and computer program product is provided for detecting if a vehicle has spun. A normal force and a lateral force of each of a front and rear axle of a vehicle is estimated. A coefficient of friction representative of a surface is estimated. Lateral momenta of the front and rear axles based on the coefficient of friction and the normal and lateral forces is calculated. Whether a surplus momentum is present, is determined. If the surplus momentum is present, a yaw rate of the vehicle is integrated respect to time to obtain a vehicle rotation estimation.

The wheel carrier (1) is connected to the carrier element (5) via a first guide (3; 17) and a first pivotable connection (10) and the wheel carrier (1) is connected to the carrier element (5) via a second guide (2; 4) and a second pivotable connection (8; 12). A first angle-measuring device (27, 28) is integrated in the first pivotable connection (10) and a second angle-measuring device (44, 45) is integrated in the second pivotable connection (8; 12).
摘要:
A vehicle-behavior detecting apparatus including a first-yaw-moment calculating unit, a second-yaw-moment calculating unit, and an indication-value calculating unit. Based on a linear bicycle model, the first-yaw-moment calculating unit calculates a first-yaw-moment during constant-speed turning. The second-yaw-moment calculating unit reads the longitudinal acceleration detected by an acceleration sensor in addition to the parameters read in the first-yaw-moment calculating unit, and calculates a second yaw moment during acceleration or deceleration. The indication-value calculating unit calculates a variation value in the yaw moment showing the vehicle behavior from the difference between the first yaw moment during constant-speed turning and the second yaw moment during accelerated or decelerated turning. The variation in the yaw moment due to the vehicle-load shift during accelerated or decelerated turning is compensated for by the variation value.

A control system (24) for controlling a safety system (40) of an automotive vehicle includes a plurality of wheel speed sensors (30) generating a plurality of wheel velocity signals, a steering angle sensor (39) generating a steering actuator angle signal, a yaw rate sensor (28) generating a yaw rate signal, a longitudinal acceleration sensor (32) generating a longitudinal acceleration signal and a pitch angle generator generating a pitch angle signal and a controller (26). The controller (26) generates a longitudinal vehicle velocity in response to the plurality of wheel speed signals, the steering angle signal, the yaw rate signal, the lateral acceleration signal and the pitch rate signal. The controller (26) may determine a slip-related longitudinal velocity and a non-slip longitudinal velocity as intermediate steps.
