Abstract: A controlling apparatus for an engine includes a purge path connected to a sealing-type fuel tank and an intake system of an engine and is configured to allow purge gas containing evaporated fuel from the fuel tank to flow therethrough. A purge valve placed in the purge path is configured to adjust a flow rate of the purge gas. A calculation unit calculates a degree of opening of the purge valve based on a target introduction ratio of the purge gas, and a controlling unit controls the purge valve so as to establish the degree of opening calculated by the calculation unit. The calculation unit corrects, in high-pressure purge performed when a pressure in the fuel tank increases exceeding a predetermined pressure, the degree of opening using a tank pressure flow velocity correction coefficient K2 corresponding to an upstream pressure of the purge valve.

Abstract: A charging control apparatus for an electric vehicle comprises: a charging efficiency computation device 21 for computing the charging efficiency of a driving battery 2; a state of change computation device 22 for computing the state of change of the driving battery 2; and a switching device 25 for switching, in response to a request from a user of the vehicle, between a first charging mode in which the charger 7 is controlled based on the charging efficiency to charge the driving battery 2, and a second charging mode in which the charger 7 is controlled based on the state of change to charge the driving battery 2.

Abstract: An electric vehicle which can cool a power unit by cold airstreams without causing dew drops and a temperature rise in a vehicle interior is provided. The electric vehicle travels by operating a motor, and includes a duct having one end joined to the air conditioning unit and the other end joined to the power unit and serving as an airstream flow path via which cold airstreams are guided from an air conditioning unit to the power unit. The duct is shaped in accordance with a shape of a vehicle interior near a front passenger's seat, and being positioned under a floor at the front passenger's seat.

Abstract: A turning control apparatus for a vehicle to improve turning ability and to avoid degradation of acceleration ability is provided. The turning control apparatus comprises a first yaw controller for adjusting at least one of driving torque of a left wheel and a right wheel; a second yaw controller for adjusting a speeds difference between a front wheel and a rear wheel; and an integrated yaw controller for controlling yaw momentum of the vehicle by managing the first and second yaw controller, wherein when the yaw of the vehicle should be reduced, the integrated yaw controller controls the first yaw controller so as to decrease the driving torque of a inside wheel, which is one of the right and left wheel and is near to a center axis of turning, and the second yaw controller so as to decrease the speeds difference between the front and rear wheel.

Abstract: The invention includes a first arm which opens and closes a valve, a second arm which is driven by a cam, a third arm which drives the first arm upon receiving a displacement of the second arm, and a variable mechanism which varies a supporting point of the second arm. The second arm includes a driving surface. The third arm includes an axis member in which a driven surface coming into surface contact with the driving surface is formed. The displacement of the second arm is transferred to the third arm with slippage occurring between the driven surface and the driving surface.

Abstract: An apparatus for controlling the turning behavior of a vehicle controls the braking forces of diagonally located wheels of the vehicle independently of depression of a brake pedal to produce a target braking force difference between the controlled wheels when the vehicle is turning, thereby applying a desired yaw moment to the vehicle. The braking forces of the controlled wheels are determined taking account of actual braking forces of respective non-controlled wheels which are located on the other, right or left side of the corresponding controlled wheels.

Abstract: A steering gear ratio changing apparatus includes a first and second steering shafts arranged to be coaxial with each other. The first steering shaft is coupled to a steering wheel of a vehicle and rotatable integral therewith. The second steering shaft is coupled to a steering gear mechanism and arranged to be rotatable. First pawls are formed on one end of the first steering shaft and arranged at equal intervals along the circumferential direction of the shaft. Second pawls are formed on one end of the second steering shaft, which oppose the end of the first steering shaft, and are arranged at equal intervals along the circumferential direction of the shaft. The first and second steering shafts are coupled with each other by a torsion bar and held thereby so that the first and second pawls are engage with one another with a gap between any two adjacent first and second pawls. The width of the gaps is adjusted by actuators so as to cause a relative rotation between the first and second steering shafts.

Abstract: A control apparatus for an internal combustion engine capable of using as a fuel a regular (low-octane) gasoline, a premium (high-octane) gasoline, or a mixture of both type of gasolines. The engine produces knocks when the ignition timing is advanced beyond a reference ignition timing determined as a function of the type of gasoline being used. This ignition timing control apparatus detects the knocks, and provides as an output therefrom a signal according to the occurrence rate of the knocks which essentially indicates the type of gasoline in use. By means of this signal, this ignition timing control apparatus continuously displaces the reference ignition timing in the direction of retard angle by using a proportion factor calculator and an interpolator. At the same time, the displaced reference ignition timing is corrected by the detected knock signals on a real time basis.
