In a hybrid vehicle that selects a series mode in which an engine drives a motor generator to generate electric power and a driving motor drives drive wheels, the series mode is suspended to temporarily stop fuel supply to the engine, and the motor generator forcedly drives the engine using electric power supplied from a driving battery to perform motoring, and failure determination of the O2 sensors is performed based on oxygen concentrations of an exhaust gas from the engine detected by a front O2 sensor and a rear O2 sensor when the fuel supply to the engine is stopped and when the fuel supply is restarted after finish of the motoring.

An apparatus includes a dynamo-electric machine driving an engine, and a calculator calculating an increment in a crank angular acceleration of the engine every certain period from a base time after the driving of the engine by the dynamo-electric machine. The apparatus further includes a determiner determining that the engine has started by the dynamo-electric machine on a condition that the increment calculated by the calculator exceeds a standard value.

Engine start determining apparatus

A fuel evaporative emission control apparatus executes a first leak presence/absence determination for determining the presence or absence of leaks of fuel evaporative gases based on the detection results of a tank pressure detection portion, with a first opening/closing portion being closed, a second opening/closing portion being opened, and a third opening/closing portion being closed. The fuel evaporative emission control apparatus can determine whether leaks of fuel evaporative gases are present or absent, can pinpoint the location of the leaks, and can detect a sensor abnormality.

A changeover valve is opened, reference pressure Pb is detected, a monitoring timer is set to 0, a purge process is started, the changeover valve is closed, a pump is operated, and the monitoring timer t is started. Then, a canister internal pressure Pc is detected, a pressure deviation &#x394;Pc is calculated from the reference pressure Pb and the canister pressure Pc, and it is determined if there is abnormality such as a leak or obstruction in a fuel evaporative gas treatment portion when the pressure deviation &#x394;Pc is a first threshold &#x394;Por higher. It is determined that there is a leak when the pressure deviation &#x394;Pc is less than a second threshold &#x394;P, and it is determined that there is an obstruction when the pressure deviation &#x394;Pc is the second threshold &#x394;Por higher.

A purge solenoid valve is opened to introduce an atmospheric pressure into a fuel tank, the purge solenoid valve is closed to operate a negative pressure pump, and set an internal pressure of the tank to a reference pressure Pb. Then, a changeover valve is closed, and the purge solenoid valve is opened to cause a canister to communicate with an intake passage. Further, the changeover valve is opened, and the purge solenoid valve is closed. Then, a first tank internal pressure Po is detected and subtracted from the reference pressure Pb. If a calculated first pressure deviation &#x394;Po is larger than a first threshold &#x394;P, it is determined that there is no open sticking in a sealing valve.

An apparatus for determining a failure in a thermostat for controlling the flow of a coolant into a radiator in response to an actual water temperature of the coolant for an engine in a vehicle includes: a water temperature detector that detects the actual water temperature; a water temperature estimator that calculates an estimated water temperature of the coolant; and a failure determining unit that compares the actual water temperature detected by the water temperature detector with the estimated water temperature calculated by the water temperature estimator under cold start of the engine and determines whether the thermostat is valve-open failure. In an engine nonoperating mode including at least automatic stop of the engine, the water temperature estimator applies a behavior of the actual water temperature to an estimated water temperature calculated immediately before automatic stop of the engine to calculate an estimated water temperature in the engine nonoperating mode.

If a pressure deviation &#x394;P (amount of pressure decrease) after a first predetermined time period T1 has elapsed since a bypass valve (canister opening/closing valve) is controlled from an opened to closed state by actuating a negative pressure pump when the engine is stopped and a purge valve is opened is less than a first predetermined pressure P1, it is determined that the bypass valve is in an open sticking state, and if the pressure deviation &#x394;P is not less than the first predetermined pressure P1, it is determined that the bypass valve is not in an open sticking state. Moreover, a pressure deviation &#x394;P after a second predetermined time T2 has elapsed since the bypass valve is subsequently controlled to be opened decreases by not less than a second predetermined pressure P2, it is determined that the bypass valveis not in a closed sticking state.

A leakage judgment with respect to a fuel tank is carried out. If the fuel tank is not leaking, a leakage judgment with respect to a canister is carried out. If there is a possibility of leakage in the fuel tank, a leakage judgment with respect to the fuel tank and the canister is carried out. If it is judged that there is leakage in the fuel tank and the canister, the leakage judgment with respect to the canister is carried out.
