摘要： In a driving force control apparatus, a target driving torque TO is obtained based on a value determined by subtracting a feedback correction torque TF corresponding to a slip amount DVS from a correction reference torque TBC corresponding to a vehicle body speed VB. Slip is suppressed by a throttle control so that the engine output is reduced to the target driving torque TO. A retard command is output when the slip amount DVS and a slip rate GDVS are greater than predetermined values to retard an ignition timing of the engine, thereby suppressing an abrupt slip. When it is determined that a right and left front wheel speed difference is large and the vehicle is running on a split road, a retard command is made difficult to be reset as compared to a case where the vehicle is not running on a split road. When it is detected that the driving wheels are vibrating, particularly a differential factor is decreased and regulated only to a component to reduce the target driving torque. With the driving force control apparatus, when a slip occurs, the engine output is reduced to prevent vehicle body vibration during operation of a device to suppress a slip.

摘要： An antiskid brake system for an automotive vehicle is provided which is designed to accumulate a wheel slippage parameter indicating a slippage condition of each wheel for given program cycles and regulate the brake pressure acting on each wheel based on the accumulated wheel slippage parameters. This improves the instability of antiskid brake control due to a small variation in tire-road adhesive .mu., irregularities of a road surface, turning of the vehicle, or a difference in diameter between tires. The antiskid brake system is alternatively designed to determine a slippage condition of one of wheels of a vehicle equipped with a rotation restraint mechanism such as an limited slip differential not only based on a slippage ratio of the one of the wheel, but also based on a slippage ratio of the other of the wheels. This permits a braking force acting on each of the wheels to be regulated precisely.

摘要： A circuit for conditioning and digitizing an analog input signal that includes a control circuit taking the form of a delta modulator that has a comparator, a clock-controlled flip-flop, a digital accumulator and a digital-to-analog converter. The comparator compares the analog input signal with an adapted signal. The comparator output is conducted to the flip-flop which produces a binary data stream representative of the difference between the comparator inputs. The digital output signal is generated by the accumulator which if fed with an integration constant that is a function of the output signal of the flip-flop. The digital output signal of the accumulator is converted into a square wave signal, which corresponds to the analog input signal, by way of a digital low-pass filter and a threshold value comparator to which the mean value of the digital output signal is supplied as a threshold value.

摘要： A method for electronic traction systems using brake intervention on the low-adhesion wheel damps and thereby substantially avoids the undesired traction control oscillations, such as pull-away tramping and drive train oscillations. In particular, an interchange of the low-adhesion wheel to be controlled from one driving wheel to the other is undertaken only when the rotational speed of the previous high-adhesion wheel is greater by a certain amount than that of the previous low-adhesion wheel and when there is no longer any controlling brake pressure at the latter. Also or in addition, the threshold value for the activation of the brake intervention is set to increase traction dynamically by suitably raising the threshold value when drive train oscillation behavior is recognized.

摘要： An anti-skid braking method is provided for controlling braking force to be applied to a wheel of an automotive vehicle by detecting any wheel behavior that the wheel is about to lock. The method comprises the following steps: detecting a vertical acceleration of a vehicle body of the automotive vehicle; detecting a longitudinal acceleration of the vehicle body; reducing a value, which corresponds to the vertical acceleration, when the longitudinal acceleration falls into a range not smaller than a first predetermined value, whereby a correction value is computed; and lowering sensitivity, at which the braking force is to be reduced in response to the wheel behavior, in accordance with an increase in the correction value computed in the correction value computing step. The longitudinal acceleration detection step may detect accelerations of left and right wheels, and the correction value computing step may include a step of selecting, as the wheel acceleration to be subjected to the processing, the greater one of the accelerations of the left and right wheels detected above. An anti-skid braking system suitable for use in practicing the anti-skid braking method is also described.

摘要： A vehicle accelerometer measures vehicle acceleration and provides acceleration data subject to contamination by noise signals. The acceleration data is filtered by a filter. A predetermined function of the noise level in the acceleration data is compared with the filter error which is the difference between raw acceleration data and the filtered value of acceleration. When the filter error is less than the noise level, the filter time constant is set to establish a low cutoff frequency so that the filter rejects the noise like a conventional low pass filter. When the filter error becomes greater than the predetermined function of the noise level, the filter time constant is set to establish a higher cutoff frequency so that the filtered value of acceleration converges to the ideal value faster than would occur with the filter having the lower cutoff frequency.

摘要： Vehicle anti-lock brake control apparatus having wheel speed sensor for detecting actual speed of a vehicle wheel, solenoid-operated valve for regulating the wheel braking pressure, and controller for controlling the valve, on the basis of the detected actual speed, and vehicle ground-speed detected by ground-speed sensor. The controller controls the valve at a controlled duty cycle, which is determined on the basis of at least a wheel speed error and a time derivative of this error. The error is obtained as a deviation of the detected actual wheel speed from a target wheel speed obtained on the basis of the detected vehicle ground-speed.

摘要： The actual quotient of the engine speed and sensed speed of the driven wheels is compared to a reference quotient calculated from the engine speed and the instantaneous gear ratio. When wheel vibrations affect the sensed wheel speed signals to an unacceptable degree, the actual quotient will deviate from the reference quotient by more than a prescribed amount. A reference wheel speed calculated from the reference quotient and the engine speed will then be used to determine slippage values, which in turn are used to generate control signals from braking and limiting engine torque. The reference wheel speed may either be used to replace the sensed wheel speeds or to limit the increase in the sensed wheel speeds.
