  • Patent number: 9197012
    Abstract: A vehicle charging port locking device has a charging port and a locking mechanism. The charging port has an engaged part that engage an engaging part of a charging connector for supplying power from an external power source to the charging port when in an engaged state. A restraining member is movably mounted between a locked state in which release of the engaged part is restricted by movement of the restraining member in a locking direction to prevent the engaging part from being released from the engaging state, and an unlocked state in which release of the engaging part is permitted by movement of the restraining member in an unlocking direction that is opposite the locking direction. The restraining member can be moved in the unlocking direction by operation of an exposed part that can be operated from beneath the hood of the vehicle.

  • Patent number: 9178313
    Abstract: An electric vehicle charging port control device yields a locked state in which disengagement between an active-engagement part of a charging connector and a passive-engagement part of a charging port is restricted by a restricting member and an unlocked state in which disengagement is permitted. The restricting member is moved to in front of a predetermined position for yielding the locked state or the unlocked state by being energizingly driven by a motor. Before the active-engagement part and the passive-engagement part are engaged, the restricting member is moved in a locking direction, and subsequently in an unlocking direction.

  • Patent number: 9163577
    Abstract: To enable, with a simple control, a malfunction of a type wherein the output from a knock sensor becomes excessively large to be detected, a knock-sensor malfunction diagnosis device includes a control section configured to determine that knocking has occurred when the magnitude of a knocking vibration frequency component derived from an output signal from a knock sensor exceeds a first threshold value, and diagnose the knock sensor as malfunctioning when a prescribed diagnostic condition wherein knocking cannot occur is satisfied and the magnitude of the knocking vibration frequency component derived from the output signal from the knock sensor exceeds a second threshold value. The control section is further configured to determine that the diagnostic condition is satisfied for a time interval from a time when a predetermined time period has expired after fuel-cutoff has started to a time when the fuel-cutoff ends, during execution of the fuel-cutoff.

  • Patent number: 9162580
    Abstract: When a timer charge time zone is set by a timer charge reservation means for allowing a user to designate a predetermined timer charge time zone and a target charge amount, and timer charge is carried out from a timer charge start time previously designated, it is judged whether or not the timer charge start time should be advanced, at a time earlier by a predetermined time period than the timer charge start time. Owing to the judgment, charge of a battery can be completed at a predetermined time without enhancing a required capacity of a heater.

  • Patent number: 9162665
    Abstract: By increasing accelerator opening APO from time t1, kick-down shift is started at time t2. While the kick-down shift is carried out by changeover from a release element to an engagement element, a motor torque tTm that is increased as Tmo with an increase in accelerator opening APO is restricted as follows. In a shift initial stage from time t2 to inertia phase start time t3, motor torque tTm is restricted to not exceed upper limit value Tlimit obtained by subtracting an inertia phase progressing torque increment Tip from an inertia phase end outputtable maximum motor torque Tmo2 that is outputtable with motor rotation speed Nmo2 at inertia phase end time t4. During an inertia phase (t3-t4), the motor torque tTm is restricted to a value Tlimit+Tip.

  • Patent number: 9156330
    Abstract: A method for controlling a vehicle cabin heating system includes setting a target temperature for a vehicle cabin interior space. The method also includes measuring current temperature within the vehicle cabin interior space at a location spaced apart from a first infrared heater and spaced apart from a target surface within the vehicle cabin interior space, the first infrared heater being aimed to heat the target surface. A surface temperature of the target surface is estimated based the current temperature. The first infrared heater is controlled such that the heater is turned on in response to the estimated surface temperature of the target surface falling below the target temperature by a predetermined amount, and the heater is turned off in response to the estimated surface temperature rising above the target temperature by the predetermined amount.

  • Patent number: 9157379
    Abstract: Intermediate position feedback control is executed when valve timing of an intake valve is at an intermediate lock position, an intermediate lock is needed, and an engine revolution speed is greater than a first engine revolution speed R1. Forced lock control is executed when the valve timing of the intake valve is at the intermediate lock position, the intermediate lock is needed, the engine revolution speed is less than the first engine revolution speed R1, and the intermediate position feedback control is not being executed. As a result, even when the engine revolution speed increases in the presence of a demand that the valve timing needs to be in the intermediate lock position, it is possible to maintain the valve timing at the intermediate lock position.

  • Patent number: 9156328
    Abstract: A vehicle control device includes a wheel speed sensor and a controller. The wheel speed sensor detects wheel speed. The controller estimates a sprung mass state based on information in a predetermined frequency region of wheel speed and controls an actuator to bring the estimated sprung mass state to a target sprung mass state. The controller calculates a first wheel speed as a reference wheel speed for individual wheels. The controller calculates a second wheel speed as a reference wheel speed of front and rear wheels. The controller calculates a third wheel speed as a reference wheel speed of all wheels. The controller calculates a reference wheel speed of each wheel. The controller detects that the estimation accuracy has deteriorated when a differential among reference wheel speeds of the wheels is equal to or greater than a prescribed value.
