Filed: 1989-12-20
Abstract: PURPOSE:To secure good drivability by estimating the extent of actual engine speed in use of rotational frequency at the driven side of a torque converter in an automatic transmission at time of something wrong in a crank angle sensor. CONSTITUTION:When trouble in a crank angle sensor is judged by a crank angle sensor trouble judging means, rotational frequency at the driven side of a torque converter is detected by an engine speed detecting means, thereby judging whether an automatic transmission is in a neutral range or not. If it is in the neutral range, an engine speed setting means sets the rotational frequency at the driven side of the torque converter as engine speed, and if the automatic transmission is a range other than the neutral one, the specified compensation is applied to the rotational frequency of the drive side of the torque converter, setting this speed as the engine speed. Using this setting engine speed, if a fuel injection quantity is operated, an almost proper mixture ratio is securable in consequence.
