摘要： When the shift position is an N position or a P position during deceleration of a vehicle, or when a brake pedal is depressed even if the shift position is a D position or an R position, an engine E is stopped to prohibit an unnecessary idling operation by prohibiting the restarting of the supplying of fuel subsequent to the fuel cut by a command from an electronic control unit. If the supplying of fuel is restarted when the engine is in stoppage, a starter motor is driven automatically to start the engine. Thus, in a vehicle including an automatic transmission, the time of stoppage of the engine can be prolonged as much as possible in a range in which the operability of the vehicle is injured, thereby providing a reduction in amount of fuel consumed.

摘要： A high probability of detecting an erroneous misfire occurs when combustion becomes unstable during jolt control. Therefore, during jolt control the reliability of the misfire detection system is degraded. As a result, the misfire detection system is inactivated during jolt control by discontinuing the misfire detection, or by deliberately deeming no misfire has occurred if jolt control has occurred. Alternatively, the misfire detection sensitivity is masked during jolt control.

摘要： A system for detecting deterioration of at least one HC sensor arranged in the exhaust passage of an internal combustion engine. There is calculated a difference between an actual value of output from the HC sensor and a predetermined reference value set in accordance with at least one parameter indicative of operating conditions of the engine, while the engine is in a predetermined operating condition. The difference is compared with a predetermined value. It is judged that there is deterioration in the HC sensor when the difference exceeds the predetermined value. In another aspect of the invention, the actual value of output from the HC sensor is corrected by a value of output from the HC sensor detected and stored when the fuel supply to the engine is cut off. Then, there is calculated a difference between the corrected actual value and the predetermined reference value.

摘要： A misfire-detecting system detects a misfire occurring in an internal combustion engine. A value of sparking voltage after generation of an ignition command signal indicative of ignition timing is detected and compared with a predetermined voltage value, and it is determines based upon the results of the comparison whether or not a misfire has occurred in the engine. The determination as to occurrence of the misfire is based upon at least one of a time period over which the detected value of the sparking voltage exceeds the predetermined voltage value, and an area of a portion of detected values of the sparking voltage exceeding the predetermined voltage value.

摘要： A system for detecting deterioration of a three-way catalyst of an internal combustion engine comprises first and second HC sensors, and a central processing unit (CPU). The first and second HC sensors are arranged in the exhaust passage of the engine at locations upstream and downstream of the three-way catalyst, respectively, for detecting concentration of hydrocarbons present in exhaust gases. The central processing unit (CPU) is operable to compare an output from the first HC sensor with an output from the second HC sensor, and determine from results of the comparison whether the three-way catalyst is deteriorated.

摘要： A control system and control method for a hybrid vehicle, which properly determine based on a predicted charge amount whether or not to change a speed position, to thereby obtain a larger charge amount, thereby making it possible enhance fuel economy of the hybrid vehicle. A first charge amount is estimated which is an amount of electric power charged into a storage battery when regeneration is performed by an electric motor in a state in which the speed position of a stepped transmission is held, for a predetermined regeneration time period. Further, a second charge amount is estimated which is an amount of electric power charged into the storage battery when the speed position is changed to a target speed position within the regeneration time period, and regeneration by the electric motor 4 is performed until the regeneration time period elapses.

摘要： When an idling stop request is generated, in the case of a B zone (the discharge limited zone) or a C zone (the discharge prohibited zone), then an internal combustion engine ENG is made to continue driving, and charging of an electric storage device BATT is performed. Thereafter, when an idling stop release request is generated, in the case of the B zone, a vehicle is started by driving an electric motor MG, while continuing driving of the internal combustion engine ENG and setting a first clutch C1 to an interrupted state. On the other hand, in the case of the C zone, the vehicle is started by continuing driving the internal combustion engine ENG, and setting the first clutch C1 to the connected state.

摘要： A valve control system for an internal combustion engine, which enables the operating mode of a valve system to be switched in optimal timing while preventing the driver from feeling the switching operation so busy and at the same time securing feeling of acceleration, thereby improving drivability. A variable valve-actuating mechanism is capable of selectively switching the operating mode of a valve system including intake valves and an exhaust valve between a plurality of operating modes different in output characteristics. Whether or not the operating mode of the valve system should be switched is determined. The execution of the switching of the operating mode of the valve system based on the determination is suppressed according to a degree of suppression set depending on detected load on the engine.
