A vehicle includes an electronic control unit. The electronic control unit is configured to detect a first current value in a period in which a current path is switched to a non-conductive state by an ignition-off operation. The electronic control unit is configured to detect a second current value in a period that is after an ignition-on operation is performed and before the current path is switched from the non-conductive state to a conductive state in the case where the first current value falls out of a specified reference range. The electronic control unit is configured to diagnose that there is an abnormality of the current sensor when the second current value falls out of the reference range and to diagnose that there is no abnormality of the current sensor when the second current value falls within the reference range.

A vehicle shutter device includes first and second flaps, one actuator, and a link mechanism. The link mechanism includes a connecting rod that couples the flaps to each other such that the flaps rotate in synchronization with each other. The shutter device is provided with stoppers configured to prohibit each of the flaps from being displaced beyond a normal opening and closing range when the link mechanism is in a normal state. When coupling between the connecting rod and the first flap is released in the first pivotally attaching portion in a state where coupling between the connecting rod and the second flap is maintained in the second pivotally attaching portion, the actuator is allowed to rotate beyond a normal rotation range of the actuator corresponding to the normal opening and closing ranges of the first and second flaps.

A fuel control system obtains a measured amount of fuel consumed by an engine and one or more corresponding operating parameters of the engine and determines a fuel consumption modeled amount based at least in part on a fuel consumption model of the engine and the one or more operating parameters. The fuel consumption model associates different amounts of fuel that, when supplied to the engine, generate corresponding designated outputs of the engine. The system also determines one or more differentials between the measured amount of fuel and the modeled amount and, responsive to the one or more of the differentials exceeding a threshold value, the system identifies one or more components of the powered system that contribute or cause the one or more differentials and/or changes an amount of fuel supplied to the engine according to the fuel consumption model to obtain a desired output of the engine.

There is provided a fuel tank structure, the fuel tank structure including (1) a bag-shaped member that partitions a space within a fuel tank into a first space at an outer side and a second space at an inner side, (2) a first pressure sensor that senses pressure of the first space, (3) a second pressure sensor that senses pressure of the second space, (4) a pump that reduces pressure of the first space, and (5) a control section that, in a case in which the pressure of the first space is higher than a first threshold value, judges that a hole has formed in the fuel tank, and, in a case in which the pressure of the second space is lower than a second threshold value, judges that a hole has formed in the bag-shaped member.

A wheel hub safety device is for a vehicle having a hub and a wheel. The hub having a plurality of opposing equiradially disposed wheel bolts. The wheel having a plurality of opposing equiradially disposed holes spaced for mating engagement with the wheel bolts on the hub. The wheel is configured for attachment to the hub through use of a plurality of lug nuts. The wheel hub safety device has a housing and a plurality of lug nut rotation detectors. The housing is for housing the plurality of lug nut rotation detectors, at least one sensor and a transmitter.

In a vehicle that includes an engine including a starter, an automatic transmission unit having an input shaft coupled to an output shaft of the engine via a first clutch, and a motor generator (hereinafter, referred to as MG) coupled to the input shaft of the automatic transmission unit via a second clutch, an electronic control unit starts up the engine with the use of the starter in a state where the MG is disconnected from the engine by releasing at least one of the first clutch or the second clutch when an IG-on operation has been made in an IG-off state (a state where the vehicle is stopped in a P range) and a power control unit that supplies electric power to the MG has a failure.

An electric vehicle includes a motor control unit. The motor control unit is configured to repeatedly execute a communication disruption determination for determining whether communication with a main control unit is disrupted; output a communication disruption signal when the motor control unit determines that the communication is disrupted; change a determination procedure of the communication disruption determination such that the communication disruption determination is completed in a shorter time when a crash possibility signal is received prior to the communication disruption determination, than when the crash possibility signal is not received prior to the communication disruption determination; and control a discharge circuit to discharge the electric charge of the smoothing capacitor, when the crash possibility signal is received prior to the communication disruption determination and the communication disruption signal is output.

A failure determination device of a hybrid vehicle, includes an engine, a motor arranged in series with the engine, a clutch arranged between the motor and a driving wheel, a pressure adjusting mechanism that adjusts hydraulic pressure supplied to the clutch, and that performs wet start clutch control for adjusting the hydraulic pressure, supplied to the clutch at least upon starting, to the hydraulic pressure causing the clutch to slip, and a controller configured to calculate required driving force on the basis of accelerator opening, and calculate torque capacity of the clutch, required for transmitting the required driving force by the clutch, as target torque capacity, calculate actual torque of the engine and actual torque of the motor, and calculate a torque deviation as a deviation between the target torque capacity and a sum of the actual torque of the engine and the actual torque of the motor.

A method for determining whether an error is present or not in a motor vehicle, a discrete state, in which the motor vehicle is presently in, being ascertained with the aid of a state machine, a decision being made, depending on the ascertained discrete state, whether an error is present or not, whereby the states of the state machine include acceptable states and unacceptable states, then, if the ascertained discrete state is an unacceptable state, the motor vehicle is transferred into an acceptable state.

There is provided a fuel tank structure, the fuel tank structure including (1) a bag-shaped member that partitions a space within a fuel tank into a first space at an outer side and a second space at an inner side, (2) a first pressure sensor that senses pressure of the first space, (3) a second pressure sensor that senses pressure of the second space, (4) a pump that reduces pressure of the first space, and (5) a control section that, in a case in which the pressure of the first space is higher than a first threshold value, judges that a hole has formed in the fuel tank, and, in a case in which the pressure of the second space is lower than a. second threshold value, judges that a hole has formed in the bag-shaped member.
