摘要： A system is described for minimizing engine torque disturbances that would otherwise cause degraded drive feel by a vehicle driver. The system utilizes multiple torque transmission paths of a transaxle unit mounted to the engine. The system manipulates the torque transmitted by adjusting the clutches of multiple torque transmission paths so that the torque disturbance in the engine results in relatively constant vehicle drive torque. In one example, a potential torque increase due to variation in engine compression ratio is reduced using multiple paths of the transmission. In this way, relatively constant output torque can be maintained.

摘要： A technique for estimating a traction characteristic of a surface under a moving vehicle, such as the coefficient of friction of the surface. The traction characteristic can be estimated by generating a torque signal representative of at least an estimate of the amount of torque applied to the driven wheels of the vehicle. A load signal representative of at least an estimate of the load or weight applied to the driven wheels also is generated. The value of the torque signal is divided by the value of the load signal in order to generate a characteristic signal. Depending on the amount of slippage between the driven and non-driven wheels of the vehicle, the characteristic signal can be stored in order to provide an estimate of the traction characteristic of the surface in real time.

摘要： An electronic traction controller for a vehicle reduces oscillations between a pair of driving wheels which may occur when the the traction controller attempts to control wheel spin of the driving wheels on surfaces which have differing frictional resistances, such as roads partially covered by snow and ice. The traction controller estimates the coefficient of friction beneath each of the driving wheels, and if the frictional resistance of the surfaces beneath each of the driving wheels varies by more than a predetermined amount, or if only one wheel is spinning, a value indicative of the inertia torque of the driving wheel and powertrain combination is determined, and compared against a predetermined value. A slip error value for each of the driving wheels is generated, which is indicative of the difference between the actual rotational speed of the driving wheel and the desired rotational speed of the driving wheel. If the inertia torque is greater than the predetermined value then braking values for the driving wheels to control wheel spin are generated as a function of the slip error value. The braking values are generated such that a first braking value is generated for the driving wheel which has the higher rotational speed of the two driving wheels, and a second braking value is generated for the other driving wheel, with the second braking value resulting in a braking force which is proportional to the first braking value.

摘要： Techniques for controlling the spin of driven wheels of a vehicle also including non-driven wheels and an engine controlled by a spark angle and/or throttle position. The spark angle is controlled by a signal responsive to a slip error signal and a slip error derivative signal in order to alter the spark angle in a manner that controls the spin of the driven wheels. The throttle position is controlled by a throttle position control signal that is responsive to a slip error signal, a slip error derivative signal, and a slip error integration signal, in order to adjust the throttle position in a manner that controls the spin of the driven wheels. Wheel spin also can be controlled by the combination of a spark angle control signal and a throttle position control signal.

摘要： A vehicle traction controller includes engine control and brake control routines to improve vehicle traction. The engine control routine reduces average slip of driven wheels of the vehicle by retarding spark timing and by reducing air flow into the engine via an electronically controlled throttle. The engine control routine is entered if the average wheel speed of the driven wheels is above a predetermined threshold speed. Control of spark timing is performed by a Proportional-Differential (PD) control technique. The electronically controlled throttle is controlled by a Proportional-Integral-Differential (PID) control technique. The brake control routine operates to reduce the rotational speed of the driven wheel which has the highest rotational speed. The brake control routine is entered if one of the driven wheels has a rotational speed which is greater than a maximum desired speed and if the difference in speed between the driven wheels is greater than a maximum difference value. A PD control technique is employed to determine the amount of braking force generated by the brake control routine. Braking force generated by the brake control routine is gradually reduced when the rotational speed of each of the driven wheels falls below a threshold value.

摘要： A vehicle traction controller controls vehicle traction and directional stability by determining the rotational velocity of the vehicle. The rotational velocity of the vehicle is measured and compared to a predefined range. If the rotational velocity is outside of the predefined range, then a wheel torque value, which is indicative of a braking force to be applied independently of driver initated braking, is generated for each wheel which is on a side of the vehicle as determined by the rotational velocity. The wheel torque value is compared to a range of values, which is based on road surface friction, and altered if the wheel torque value is outside of the range of values. Wheel spin and skid control is employed to reduce wheel spin and skid.
