摘要： A driving wheel slip control system for a vehicle detects an excessive slip state of at least one of the driving wheels of the vehicle and reduces engine output when the excessive slip state is detected, by repeating alternate fuel cut and fuel supply such that fuel supply is stopped for a first predetermined time period, and a second predetermined time period. During the second predetermined time period the engine is supplied with an amount of fuel smaller than one required for an operating condition of the engine in the excessive slip state. If the excessive slip state has a greater variation in magnitude than a certain value, fuel supply is continuously effected for a third predetermined time period longer than the first predetermined time period or all the time during the excessive slip state. In another embodiment, slip value is determined which corresponds to the degree of an excessive slip of the driving wheel and a supply controller controls the amount of fuel supplied to various engine cylinders depending on the slip value. A fuel cut-off control cuts off the fuel supply to the various cylinders the number of which depends on the slip value when the slip value exceeds a predetermined slip value.

摘要： A system for controlling the slip of driving wheels of a vehicle detects an excessive slip state of at least one of the driving wheels of the vehicle wherein the slip of the at least one driving wheel has a magnitude greater than a predetermined magnitude, and interrupts fuel supply to the engine of the vehicle when the excessive slip state is detected. The system further detects a predetermined smaller slip state wherein the slip has a magnitude less than the predetermined magnitude. An amount of fuel supplied to the engine is corrected in dependence on the value of at least one predetermined operating parameter of the engine, which is sensed by at at least one parameter sensor, when the predetermined smaller slip state is detected. A plurality of different correction values responsive to operating conditions of the engine, which correct the amount of fuel supplied to the engine, are rendered virtually ineffective when the predetermined smaller slip state is detected.

摘要： In reducing the output from an internal combustion engine by a driving-wheel torque reducing means when a driving wheel is slipping excessively, thereby inhibiting the excessive slipping of the driving wheel, a total torque transmitted from the internal combustion engine to the driving wheel and a surplus torque consumed for the excessive slipping of the driving wheel are found, and the output from the internal combustion engine is reduced on the basis of an effective driving-wheel torque found from the total driving-wheel torque and the surplus torque and transmittable to a road surface. Alternatively, the output from the internal combustion engine may be reduced on the basis of the total torque transmitted from the internal combustion engine to the driving wheel and the surplus torque consumed for the excessive slipping of the driving wheel. Consequently, the driving-wheel torque can be converged quickly to a proper value, and it is possible to provide a closer control of the driving-wheel torque.

摘要： An excess slip control device for a driving wheel, comprising a driving wheel speed sensor for detecting a driving wheel speed of a vehicle, a slip determining means for determining a slip condition of a driving wheel according to an output from the driving wheel speed sensor, a fuel supply suppressing means for suppressing fuel supply to an engine according to an output from the slip determining means, and a retard control means for controlling an ignition timing to a retard position according to an output from the slip determining means. Thus, the fuel quantity to be supplied to the engine and the ignition timing are controlled according to the slip condition of the driving wheel. Accordingly, an operational shock due to a fluctuation in engine torque may be reduced to thereby improve the drivability, and a control lag may be also eliminated.

摘要： A driving wheel slip control system for a vehicle equipped with an internal combustion engine, in which a decelerating condition of the engine is detected, a slip state of the driving wheels is detected, and the torque of the driving wheels is reduced in response to the detected slip state of the driving wheels. The torque reduction is inhibited irrespective of the detected slip state when the decelerating condition of the engine is detected. The engine is determined to be in the decelerating condition when the engine is in a region where the air-fuel ratio of a mixture being supplied to the engine is to be controlled to a value leaner than a stoichiometric ratio.

摘要： When the output from an internal combustion engine is reduced using a combination of a throttle valve control device, a fuel cut control device and an ignition retard control device, the starting point of operation of the ignition retard control device in a control region of condition for an excessive slipping of the driving wheel is provided between the starting region of operation of the throttle valve control device and the starting region of operation of the fuel cut control device. This permits the fuel cut control device to have a high responsiveness to a sudden variation in excessive slipping and no exhaust heat to be discharged, and also permits the throttle valve control device to become lower in responsiveness after the excessive slipping has been substantially converged but to have a small variation in fuel-air ratio. The ignition retard control device starts operation only when the excessive slipping cannot be suppressed by the throttle valve control device. Therefore, the use of the ignition retard control device which relatively easily permits an increase in the temperature of an exhaust gas can be restrained to the minimum.

摘要： A method for controlling the fuel supply of an internal combustion engine determines the fuel supply amount on the basis of sampled values of a pressure level within an intake pipe of the engine when the engine is operating outside of an idling range, and determines the fuel supply amount on the basis of sampled values of rotational speed of the engine when a predetermined time period has passed after the entrance of the engine operation into the idling range, and an idling speed of the engine is stabilized. Thus, a change in the engine rotational speed upon the start of idling which has been occurred in the prior art is eliminated.

摘要： A method of effecting feedback control of the air-fuel ratio of an air-fuel mixture supplied to an internal combustion engine to a first predetermined value, by correcting a basic fuel supply quantity by the use of a correction coefficient variable in response to the output of an exhaust gas ingredient concentration sensor, when the engine is operating in a predetermined feedback control region. A predetermined engine low-load operating region outside the predetermined feedcback control region is defined by at least one parameter representing load on the engine. When the engine enters the predetermined low-load operating region, the correction coefficient is gradually decreased until the air-fuel ratio of the air-fuel mixture is increased to a second predetermined value leaner than the first predetermined value. When the engine enters the predetermined feedback control region from the predetermined low-load operating region, the initial value of the correction coefficient is set to the product of a value of the correction coefficient obtained immediately before the engine enters the predetermined feedback control region and a predetermined enriching coefficient, and the set initial value is gradually increased until the air-fuel ratio of the air-fuel mixture is decreased to the first predetermined value.

摘要： After starting of an internal combustion engine, a quantity of fuel to be supplied to the engine is increased by the use of a fuel increment, and at the same time a period of time is counted which elapses from the time an oxygen concentration sensor has its internal resistance decreased below a predetermined value. When the period of time counted exceeds a predetermined period of time, the increase of the quantity of fuel is terminated and simultaneously calculation of a correction value responsive to oxygen concentration in exhaust gases sensed by the sensor is started, and the quantity of fuel is corrected by means of the correction value calculated. A temperature in the engine intake system is sensed, and the above predetermined period of time is to a larger value as the sensed intake system temperature is higher.

摘要： A method of controlling the supply of fuel to an internal combustion engine after starting, wherein an initial value of a fuel increment is set to a value dependent upon a temperature of the engine after starting thereof, the fuel increment is progessively decreased from the set initial value thereof at a predetermined rate, and a fuel quantity corrected by the decreased fuel increment is supplied to the engine. A temperature of the intake system of the engine is sensed. The above predetermined rate of decrease of the fuel increment is set to a larger value as the sensed temperature of the intake system is higher. Preferably, when the sensed temperature of the intake system is higher than a predetermined value corresponding to the boiling point of fuel, the predetermined rate of decrease of the fuel increment is set to a larger value than that to which it is set when the sensed temperature is lower than the predetermined value.
