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.
