摘要： A feedforward throttle adjustment for a closed loop idle speed control provides engine power output required to drive a variable power steering load while maintaining the engine idle speed in a desired range. The working pressure of the power steering system is detected, and the change in such pressure in the course of a steering maneuver is used to initiate an increase in the engine power output setting. The increase is determined in relation to the peak pressure change; it is implemented at a pedetermined rate, and is subject to interruption whenever the pressure change indicates that the steering maneuver has ended.

摘要： A throttle follower controller for establishing a release throttle position upon the release of the throttle by the vehicle operator which is maintained at a specified value for a predetermined time if the vehicle transmission is experiencing an upshift or if an upshift will occur upon the release of the throttle to provide for a smooth upshift. Upon completion of the upshift or if no upshift will occur upon release of the throttle, a controlled transition of the throttle angle to a predetermined lower coastdown value is established to prevent drive-on while preventing a sudden harsh drive line jerk upon release of the vehicle throttle.

摘要： An idle speed control motor under computer control positions a throttle stop for setting minimum throttle angles. The motor response to actuating pulses varies from motor to motor so that a gain factor is determined for each motor and is used to calculate the required pulse width to attain a desired throttle displacement. A gain learn program in the engine control computer runs when the ignition is turned off and is effective to extend the motor with a number of pulses of known width, measure the throttle displacement, and determine the gain factor by dividing a standard displacement by the measured displacement. The same program is applied to learning the gain of a throttle motor in an electronic throttle control system.

摘要： The fuel control routine of an engine control module sets a cold enrichment schedule used for engine starting when the engine is cold. The enrichment value is dependent on coolant temperature. To prevent plug fouling in a new vehicle subject to short engine run times, the enrichment value is reduced if the mileage is below 50 miles, the coolant temperature is within set limits and the previous engine run time was shorter than a set period.

摘要： Potentially damaging operation of a viscous converter clutch (VCC) is detected in relation to the slippage thereacross. The slippage is compared with a reference slip value indicative of excessive VCC slippage to develop a net overslip indicator. The value of the net overslip indicator changes in the direction of a first limit value so long as the detected slip is at least as great as the reference slip, and in the direction of a second limit value so long as the detected slip is less than the reference slip. When the net overslip indicator reaches the first limit value, the friction clutch is disengaged to release the VCC. According to a first embodiment, the transmission fluid temperature at the time of such deactivation is measured and stored, and the VCC is reactivated when transmission fluid temperature falls below the stored temperature, assuming other criteria for activation are also met. According to a second embodiment, the VCC is reactivated a predetermined time after its deactivation and measurement of the transmission fluid temperature is not required.
摘要翻译：相对于其中的滑移检测粘性转换器离合器（VCC）的潜在的破坏性操作。将滑移与表示过度的VCC滑动的参考滑动值进行比较，以形成净超尺寸指示器。只要检测到的滑移至少与基准滑差一样大，则净过大指示器的值在第一极限值的方向上变化，并且在第二极限值的方向上，只要检测到的滑差小于参考单。当净超量指示器达到第一极限值时，摩擦离合器脱开以释放VCC。根据第一实施例，测量并存储在这种去激活时的传输流体温度，并且假设传输流体温度低于存储温度时VCC被重新激活，假设还满足了激活的其他标准。根据第二实施例，在停用VCC之后的预定时间内再次激活VCC，并且不需要传输流体温度的测量。

摘要： An engine spark timing control system and method for addressing various engine output torque constraints. Preignition and knock concerns are addressed according to the conventional practice of calibrating spark control table, and the most limiting of the drivetrain-related torque constraints is referenced to such table to determine the additional retard, if any, required to satisfy such constraint. With this control, the preignition spark control table or any of the drivetrain-related torque constraints may be changed at will without violating the other constraints or calibrations.

摘要： In a method of traction control, fuel injectors are selectively disabled to unfuel respective cylinders of an engine to reduce engine torque output. The method provides for limiting the number of cylinders that can be disabled for acceleration spin control based on engine and vehicle operating parameters to improve traction control performance and provide protection for the vehicle catalytic converter.

摘要： The ratio air and fuel mixture delivered to the fueled cylinders of an engine of a vehicle is controlled while selective cylinders of the engine are unfueled to reduce engine torque output to inhibit excessive wheel spin during vehicle acceleration. The air/fuel ratio of the mixture delivered to the fueled cylinders is increased as cylinders are selectively unfueled to reduce engine torque output and power enrichment to the fueled cylinders is inhibited when any cylinders are unfueled to reduce engine torque output for traction control and for a time period after all cylinders are again fueled.

摘要： A vehicle suspension comprises dampers changeable between low and high damping modes and normally operated in the low damping mode. A damper control stores a plurality of sets of reference numbers as a function of vehicle velocity, the reference numbers of each set representing limit values of throttle velocity for the low damping mode for a given transmission gear mode. The reference numbers of each set increase in value with increasing vehicle velocity in a continuously non-linear manner so as to compensate for the decreasing acceleration and body lift produced by a given throttle velocity as vehicle velocity increases. The control changes the damper from low to high damping during vehicle acceleration for a predetermined time when the throttle velocity exceeds a throttle velocity limit reference derived from the reference number corresponding to the vehicle velocity in the set corresponding to the selected transmission gear mode. The control further changes the dampers from low to high damping for a predetermined time when vehicle deceleration exceeds a reference, when a transmission shift occurs or when engine torque first exceeds a reference.
摘要翻译：车辆悬架包括在低阻尼模式和高阻尼模式之间可变的阻尼器，并且通常在低阻尼模式下操作。减震器控制器存储多组参考号作为车速的函数，每组的参考编号表示对于给定的变速档模式的低阻尼模式的油门速度的极限值。每组的参考数字以连续非线性方式随着车辆速度的增加而增加，以补偿由于车辆速度增加而由给定的油门速度产生的减小的加速度和车身升力。当节气门速度超过对应于对应于所选择的变速档模式的组中的车辆速度的参考数字的节气门速度极限参考值时，控制器在车辆加速期间将阻尼器从低阻尼改变为高阻尼。当车辆减速度超过基准时，当变速器换档发生时或者当发动机扭矩首先超过基准时，该控制进一步将阻尼器从低阻尼改变为高阻尼预定时间。
