    • A motor vehicle drive has an engine and an automatic transmission. A control for the motor vehicle drive includes an engine control for controlling a variable influencing torque of the engine and a transmission control for controlling shifting events of the transmission and for transmitting an intervention signal initiating a shifting event to the engine control. The transmission control includes a first device for ascertaining a current transmission input torque, a memory for storing torque values being maximally allowable during a shifting event, as a function of engine rpm and shifting type, a second device for comparing the current transmission input torque with the maximum allowable torque value at any given time and ascertaining a proportion by which the engine torque is to be varied during the shifting event, and a pulse former circuit for converting the proportion into a pulse modulated signal to be transmitted to the engine control as a control signal for controlling a variation in the engine torque during the shifting event.

    • A control system for a motor vehicle drive includes an engine control configuration for controlling a variable influencing torque of an engine. A transmission control configuration controls shifting operations of an automatic transmission with a torque converter and transmits an intervention signal to the engine control configuration to carry out an intended shifting operation in a jerk-free and low-wear manner. The transmission control configuration has a circuit configuration for determining a fraction by which the engine torque is to be changed for the shifting operation. The fraction is determined as a function of a transmission input torque obtained from a converter amplification determined by the transmission control configuration and the engine torque determined by the engine control configuration, and as a function of the type of shift. The fraction is transmitted to the engine control configuration as control information for altering the engine torque.
    • 用于机动车辆驱动器的控制系统包括用于控制发动机的可变影响转矩的发动机控制构造。 变速器控制构成利用变矩器来控制自动变速器的换档动作,并将干预信号发送到发动机控制结构,以无冲击和低磨损的方式进行目标变速操作。 变速器控制结构具有用于确定变速操作时发动机转矩变化的分数的电路结构。 根据由发动机控制结构确定的转换器放大和由发动机控制配置确定的发动机转矩以及作为变速类型的函数确定的变速器输入转矩的函数来确定分数。 该分数被传输到发动机控制构造,作为用于改变发动机扭矩的控制信息。
