    • A control apparatus for an automatic transmission calculates the running resistance of a vehicle based on the vehicle acceleration and the torque generated by the engine. When the running resistance exceeds a first prescribed value, it is determined that the vehicle is travelling on an uphill slope on which upshifting should not take place, so the transmission is prevented from upshifting. When the running resistance falls below a second prescribed value, it is determined that the vehicle is travelling on a downhill slope, so the transmission is made to downshift to a gear in which the engine of the vehicle will perform engine braking. When the running resistance is between the first and second prescribed values, the control apparatus controls the transmission based on the vehicle speed and the throttle opening.
    • 用于自动变速器的控制装置基于车辆加速度和由发动机产生的转矩来计算车辆的行驶阻力。 当行驶阻力超过第一规定值时,确定车辆在不应发生升档的上坡上行驶,因此防止变速器升档。 当行驶阻力下降到第二规定值以下时,判定车辆在下坡上行驶,从而使变速器降档到车辆的发动机将进行发动机制动的齿轮。 当运行阻力在第一和第二规定值之间时,控制装置基于车速和节气门开度来控制变速器。

    • A current control circuit for controlling a current supplied to the coil 3 of an electromagnetic type actuator includes a power transistor 2 and a current detecting resistor 4 coupled in series with the coil 3. The voltage across the current detecting resistor 4 is amplified by a differential amplifier 10 and held by a capacitor 8 of a peak hold circuit 6. The input pulse signal A is smoothed by a smoothing circuit 14. A differential amplifier 18 compares the outputs C of the smoothing circuit 14 with that D of the peak hold circuit 6. The output of an OR gate 20 turns on the power transistor 2 either when the input pulse A or the output of the differential amplifier 18 is at the high level. The voltage held across the capacitor 8 is reset by the transistor 9 in response to the output of the OR gate 20. The duty factor of the power transistor 2 is automatically adjusted to compensate for the variations in the circuit characteristics.
