摘要： Herein disclosed is a revolution signal processing system for an electronic controller to ensure safe operation of a vehicle having an automatic transmission. The system includes: an input shaft revolution sensor for outputting an input shaft r.p.m. signal; a vehicle speed sensor for outputting a vehicle speed signal; signal processors for determining the r.p.m.'s of the two sensors in response to the two output signals of the same; a gear position sensor for outputting a gear position signal; a gear position detector for detecting the gear position of the automatic transmission; and a self-testing backup. When the gear position detector detects that the transmission is in a gear position other than the neutral position, and if one of the output signals of the two sensors exhibits an r.p.m. equal to or higher than a predetermined value, whereas the other of the same exhibits an abnormally lower value or an r.p.m. lower than the predetermined value, then the self-testing back up determines that the sensor having the output signal exhibiting the abnormally low value is malfunctioning. Thus, the revolution signal processing system self-tests and backs up the vehicle speed sensor and the input shaft revolution sensor.

摘要： An automatic clutch control system and method for controlling a clutch for an automatic transmission when a clutch stroke sensor fails. The apparatus includes a clutch actuator for controlling a clutch stroke, a plurality of solenoid valves for controlling the clutch actuator, a clutch stroke sensor for measuring the clutch stroke, a control unit for feeding back a stroke signal detected by the clutch stroke sensor when requests for clutch engagement or disengagement are received and for controlling the solenoid valves so as to obtain a clutch moving speed defined by an engine rotational speed and other driving conditions. The control unit further includes a clutch engagement control section and a clutch disengagement control section for controlling solenoid valves for operating the clutch independently of the stroke signal when the stroke sensor fails. The control unit detects a failure of the stroke sensor by defining an upper limit value and a lower limit value for the stroke signal and when the stroke signal exceeds the upper limit value or is lower than the lower limit value it is determined that the stroke sensor has failed. The method includes the steps of setting the upper and lower limit values for the stroke signal, detecting a clutch stroke sensor failure by determining if the value of the stroke signal exceeds the upper limit or is less than the lower limit and operating the clutch at a predetermined speed if a stroke sensor failure is detected.

摘要： Herein disclosed is a method of processing a malfunction of an accelerator pedal sensor of an automobile. An output voltage is outputted according to changes in a resistance depending upon depression of an accelerator pedal. A malfunction of the accelerator pedal sensor is shot to process and determine an acceleration value for controlling the run of the automobile in accordance with said output voltage. The acceleration value is set at a predetermined value in accordance with the malfunction of either of an idle switch for generating a signal indicating the idle position of the accelerator pedal and a wide-open switch for generating a signal indicating the wide open position of the accelerator pedal when the malfunction of the accelerator pedal sensor is judged. This judgement is conducted by detecting a plurality of times that said output voltage is outside of the predetermined voltage range. The acceleration value is set at a predetermined minimum value, when the idle switch is in a normal state, at a predetermined relatively high value, when the wide-open switch is in a normal state, and at a predetermined relative low value when both the two switches are troubled.

摘要： A method of controlling a synchromesh type automatic transmission of a vehicle such as an automobile, including the steps of releasing a clutch for connecting an engine and the transmission in response to a speed change command, shifting the transmission from one speed position to a neutral position, shifting the transmission from the neutral position to a subsequent speed position, and applying the clutch. The double-clutching operation is conducted if a load upon synchronization during the speed changing operation exceeds a predetermined level, to once apply the clutch and subsequently release the clutch again while the transmission is in the neutral position. Thus, the synchronization load can be dropped to prevent any so-called "under-synchronization" in the transmission. The synchronization load is detected in terms of the difference between the r.p.m. of the input shaft of the transmission and the product of the vehicle speed or the r.p.m. of the output shaft of the transmission and the reduction ratio.

摘要： An automatic clutch control system, for use in automobiles, using a microcomputer. Included in the system are an accelerator pedal sensor for detecting accelerator position; an engine speed sensor for detecting engine speed; a clutch stroke sensor for detecting clutch stroke; and an automobile speed sensor for detecting automobile speed. The microcomputer is included in a controller for controlling opening or closing of solenoid valves, gear change of a transmission, and opening or closing of a throttle actuator, based on predetermined stored data and based on signals transmitted from the sensors. The automatic clutch control system consequently can automatically control the clutch moving time and clutch moving speed for easy driving under all driving conditions. Moreover, while the clutch control system is fully automatic, it can use dry-type single-plate clutches and sliding-mesh-type transmissions as in manual and semiautomatic transmissions.

摘要： A method of controlling the gear changing operation in an automatic transmission having a gear transmission actuatable by a gear changing actuator assembly controlled by an electronic control system. When operating the gear changing actuator assembly for a gear changing operation, an interval of time, which elapses after the gear changing actuator assembly is operated, is measured with a timer. The measured interval of time is compared with a preset interval of time. When a lock is detected as being caused at the time the gear changing operation is not completed within the preset interval of time, the gear changing actuator assembly is operated to a gear position different from a gear position which the gear changing actuator assembly has originally been operated to select.
