    摘要： A lock-up control device in which a pulse train is generated which has a duration which increases as the vehicle speed decreases. A counter generates a period indicative signal indicative of a current period of the pulse train. A memory stores the period indicative signal for a preceding period. An adder generates an adder signal indicative of the addition of a preset value to the period indicative signal stored in the memory. A comparator compares the adder signal with the period indicative signal generated by the counter and generates a comparator signal when the former is larger than the latter. A flip-flop generates a flip-flop signal when the comparator signal occurs under the presence of a lock-up signal. An AND gate provides a lock-up release signal when said flip-flop signal occurs irrespective of the presence of the lock-up signal.

    摘要： The lock-up control system stores lock-up speed values for each gear position of the transmission. These values are compared against actual vehicle speed to control lock-up of the transmission. In the system, a counter receives clock pulses from a clock and sensor pulses from a vehicle speed sensor. The sensor pulses have a frequency indicative of information related to vehicle speed. The counter counts sensor pulses within a time interval between two adjacent clock pulses. This count is therefore indicative of vehicle speed.

    摘要： The lock-up control system functions to temporally release lock-up operation of a torque converter of the transmission upon occurrence of a gear shift signal even if the automotive vehicle is operating within lock-up range. A plurality of gear shifting detectors are provided, each generating a gear shift signal when triggered. Gate means function to select one of said plurality of gear shifting detectors in response to engine load for allowing transmission of a gear shifting command to a selected gear shifting detector. Delay means are provided to retard transmission of the gear shifting command to the plurality of gear shifting detectors in such a manner that a delay between the occurrence of the gear shifting command and the occurrence of the gear shift signal increases as the engine load decreases.

    摘要： A lock-up control system for a lock-up type automatic transmission of an automotive vehicle.The lock-up control system functions to temporally release lock-up operation of a torque converter of the transmission upon occurrence of a gear shift signal even if the automotive vehicle is operating within any one of lock-up ranges. Gear shifting detector means generates a gear shift signal having a time duration which is variable corresponding to the time duration of a corresponding gear shifting operation. The duration of the gear shift signal generated by the gear shifting signal may also be variable also with the magnitude of engine load.

    摘要： A lock-up control system for a lock-up type automatic transmission.A load detection circuit generates a reference acceleration signal that indicates a reference acceleration, and an actual acceleration signal that indicates an actual acceleration of an automotive vehicle. The circuit compares the actual acceleration signal with the reference acceleration signal for generating a first command signal when the actual acceleration signal is greater than the reference acceleration signal and generating a second command signal when the actual acceleration signal is smaller than the reference acceleration signal. The first command signal is fed to a first vehicle speed comparator means to render it operative. The second command signal is fed to a second vehicle comparator means to render same operative. Each of the first and second comparator means compares the vehicle speed signal with a set of reference vehicle speeds for generating a plurality of patterns of signals that indicate a corresponding plurality of lock-up ranges.
