摘要： A system for automatically stopping and starting an engine of a vehicle which enables proper determination of whether the stopping of the engine is possible, in accordance with the state of a battery. A power brought out from the battery by auxiliaries is subtracted from a power generated by a generator, thereby calculating a difference corresponding to a power for actually charging the battery. By sequentially adding the value, an integrated value of power charged in the battery is calculated. Meanwhile, a value of a known power WBRK consumed by a brake lamp plus a current power consumed by the auxiliaries is multiplied by a beforehand determined target value of idling-stoppage duration, thereby evaluating an evaluated integrated value of power consumed by the battery during stoppage of an idling. If the integrated value is not less than the evaluated integrated value, the stopping of the engine E is permitted.

摘要： An evaporative fuel processing system adapted to be capable of detecting abnormality of an evaporative emission control system for storing, in a canister, evaporative fuel from a fuel tank for holding fuel to be supplied to an internal combustion engine, and purging evaporative fuel into the intake system of the engine. A first control valve is arranged across a passage extending between the fuel tank and the canister. A second control valve is arranged across a passage extending between the canister and the intake system of the engine. A third control valve is provided for an air inlet part of the canister communicatable with the atmosphere. Through operating these control valves to open and close them, the evaporative emission control system is negatively pressurized, and abnormality of this system is detected based on the pressure detected in this negatively pressurized state thereof. Timing for carrying out abnormality determination is determined depending on conditions of the fuel tank. Before starting the whole process for abnormality diagnosis of the system evaporative fuel stored in the canister is allowed to be purged for a predetermined time period. When the temperature of fuel in the fuel tank exceeds a predetermined value, the abnormality determination is inhibited.

摘要： A hybrid vehicle control apparatus for improving fuel consumption ratio by making appropriate the deceleration perception of the hybrid vehicle is provided. It is determined whether the flag setting of a brake ON determination flag is “1”. If the brake is OFF, a brake OFF regeneration amount is obtained, and is assigned to the deceleration regeneration computed value. It is determined whether a remaining batter charge is greater than or equal to a predetermined normal power generation mode execution upper limit remaining charge. In the case where the determination result is yes, it is determined whether a control vehicle speed is greater than or equal to a predetermined high speed deceleration regeneration reduction lower limit vehicle speed. In the case where the determination result is yes, the value obtained by multiplying the deceleration regeneration computed value by a predetermined high speed deceleration regeneration reduction coefficient, for example 0.8, is set as a new deceleration regeneration computed value.

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 combustion state-determining system for an internal combustion engine has an ECU which determines a misfiring state of the engine, and calculates a misfiring rate of the engine, based on the result of the determination of the misfiring state. A catalyst temperature sensor detects the temperature of a catalytic converter as the exhaust system temperature, and the ECU determines the combustion state of the engine, based on the detected exhaust system temperature and the calculated misfiring rate. A combustion state control system restrains the output from the engine, based on the determination result of the combustion state-determining system.

摘要： A catalyst deterioration-determining system determines deterioration of a catalyst arranged in the exhaust passage of an internal combustion engine. An ECU is responsive to an output from an O.sub.2 sensor arranged upstream of the catalyst or outputs from O.sub.2 sensors arranged upstream and downstream of the catalyst for controlling the air-fuel ratio of a mixture supplied to the engine by means of an air-fuel ratio correction value (first air-fuel ratio control). When the engine is in a predetermined operating condition, the system effects changeover from the first air-fuel ratio control to a second air-fuel ratio control which is responsive to the output from the downstream O.sub.2 sensor for controlling the air-fuel ratio of the mixture by means of the air-fuel ratio correction value. After the changeover has been effected, a time period is measured which elapses from the time the second air-fuel ratio control causes a change in the air-fuel ratio correction value from a richer side to a leaner side or vice versa with respect to a stoichiometric air-fuel ratio to the time the output from the downstream O.sub.2 sensor is inverted from the richer side to the leaner side or vice versa with respect to the stoichiometric air-fuel ratio. It is determined that the catalyst is deteriorated, when the measured time period is shorter than the predetermined time period.

摘要： A tank internal pressure-detecting device for an internal combustion engine having an evaporative emission control system for controlling purging of evaporative fuel generated in a fuel tank thereof into an intake system thereof. An ECU interrupts purging of evaporative fuel by the evaporative emission control system for a predetermined period of time after the engine is started. The ECU causes control valves of the evaporative emission control system to open the interior of the fuel tank to the atmosphere, and stores a value of pressure within the fuel tank detected by a tank internal pressure sensor as a reference value while the purging is being interrupted and at the same time the interior of the fuel tank is opened to the atmosphere. The ECU corrects an output value of the tank internal pressure sensor, based upon the reference value stored.

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.
