    摘要: A method for controlling/regulating a process in a motor vehicle, in particular a combustion process, gear-shifting process, or braking process, with the help of a characteristics grid map, which is defined by a plurality of performance quantities of the process and represented by data points that have corresponding characteristics-map values. At least one characteristics-map value is determined from the characteristics grid map in a control cycle for an operating point by first determining adjacent data points, which define an interpolation range in which the operating point lies, and by then interpolating between the adjacent data points. To reduce the computational time for interpolation, the at least one characteristics-map value is determined for the operating range within the framework of a linear interpolation based on a minimum number of data points. The minimum number of data points results from a number of the plurality of performance quantities of the process, which define the characteristics map, plus one.

    摘要: In an engine provided with a throttle valve actuator which controls the opening/closing of the throttle valve, a target throttle valve opening degree is determined based the amount of accelerator pedal depression. Following a speed change command being issued in an automatic transmission the target throttle position is gradually decreased until an inertial phase is detected. The target throttle opening is then returned to that which corresponds to the accelerator pedal depression by the driver. More specifically, a method of controlling a vehicle features: a speed change requirement detection which detects a speed change requirement being issued to a transmission; an input torque reduction which reduces the input torque input to the automatic transmission irrespective of the intention of the driver; a gear change period commencement time detection which detects a time corresponding to a speed change engagement commencement time during speed change; and an input torque reduction control completion step which completes the torque reduction control in a manner where, after a speed change requirement is detected, the input torque is reduced by a predetermined amount by the torque reduction step, and a time corresponding to a speed change element engagement commencement timing during speed change is detected by the gear change period commencement detection step.

    摘要: An apparatus for controlling the torque on a power train of a machine is disclosed. The power train includes an engine, a transmission, and a torque converter for transmitting torque between the engine and transmission. A torque converter speed sensor produces a torque converter speed signal and an engine speed sensor produces an engine speed signal. A gear selector device produces a gear select signal indicating a desired gear ratio. A look-up table stores an upper engine power curve and a lower engine power curve. Finally, an electronic controller receives the torque converter, engine speed and gear select signals, and selects one of the upper and lower engine power curves to operate the engine in response to the selected gear ratio and torque converter speed.

    摘要: A dithering torque control method that is useful for a semi-automated vehicle transmission facilitates accomplishing a desired condition in the transmission. The method is useful during an initial break torque function to relieve drive train torque so that a driver can move a manual shift lever from an engaged position to a transmission neutral position without using a clutch. The method is also useful for shifting a lever to move gearing components from a neutral position to a next desired gear. A dithering function is used to cyclically oscillate a current torque value about a target torque value that is associated with the desired transmission condition. An amplitude and period of the dithering function are determined based upon an overall gear ratio of the transmission. The dithering function begins at a point dependent on a torque value associated with the currently engaged gear. The dithering function continues until a known transmission condition is confirmed.

    摘要: The invention relates to an improved method for ensuring that at the time of disengagement of a gear in connection with changing gear in mechanical gearboxes without clutch disengagement the engine torque is adjusted to a zero-torque level which is continuously corrected on the basis of the instantaneous acceleration of the engine but also on the basis of the internal friction of the engine and on the basis of any power take-offs being powered by the engine.In gear changing, adjustment begins with a torque reduction at time t.sub.1. The torque is reduced to a zero-torque level M.sub.0 which is continuously variable during the reduction and which is adapted to the current engine deceleration and which is corrected by a friction factor M.sub.f and an acceleration factor M.sub.a. The friction factor M.sub.f is derived from a matrix M.sub.f (n,T) on the basis of current engine speed n and engine temperature T, and the acceleration factor M.sub.a is calculated continuously during the decrease (t1-t2) on the basis of the engine's moment of inertia and the instantaneous engine acceleration. The zero-torque level is also corrected on the basis of any power take-offs in operation, by means of a power take-off factor M.sub.pto. Both M.sub.pto and M.sub.f are updated to compensate for changes due to wear.

    摘要: A control system is provided for a vehicle regulating engine speed during shifts so as to reduce driveline torque and shift shock. The control system includes separate microprocessor based engine and transmission controllers which communicate via a data link. When a shift is initiated, the transmission controller delays a first period of time CTSDELAY sufficient for the transmission to disengage the old gear ratio and then produces a CTSSPEED signal. The transmission controller continues to produce the CTSSPEED signal for a second period of time CTSDUR which corresponds to the time required for the transmission to engage the new gear ratio. The engine controller receives the desired engine speed signal and regulates engine speed into correspondence with the desired speed. During upshifts, the CTSSPEED signal is set to a speed which is a predetermined amount above the synchronization speed of the new gear for an upshift. Conversely, during downshifts, the CTSSPEED is set to a speed which is a predetermined amount below the synchronization speed in the new gear. The control system preferably includes a unit [means] for sensing a lockup time period corresponding to the time required for the transmission to lock up in the new gear ratio. The control system is capable of modifying the second time period CTSDUR as a function of the sensed lockup time period.
