Abstract: A vehicle driving force control apparatus is provided for a vehicle having an electric motor transmitting a drive torque to a first wheel, and a clutch installed between the electric motor and the first wheel. The vehicle driving force control apparatus basically comprises a clutch control section and a motor control section. The clutch control section is configured to control engagement and release of the clutch. The motor control section is configured to control a motor response characteristic by increasing the motor response characteristic of the motor from a first response characteristic to a second response characteristic when the clutch control section releases the clutch. Preferably, the vehicle driving force control apparatus is configured to cancel insufficient torque generation due to undershoot armature current when controlling armature current of an electric motor and transmitting torque to subordinate drive wheels.

Abstract: A vehicle powertrain includes an electric motor (4) and a clutch (12) between the electric motor and a motor driven road wheel (3L, 3R). Powertrain play between the electric motor (4) and the road wheel is eliminated upon determination that powertrain play elimination (PPE) is needed for motor torque transmission to the motor driven road wheel. The PPE includes controlling engagement of the clutch and regulating the electric motor to produce a very small amount of motor torque required for PPE.

Abstract: A tape cassette and a leader-trailer tape therefor capable of ensuring safe and positive connection between a leader-trailer tape and a magnetic tape, to thereby permit the magnetic tape to travel in a cassette casing with high reliability. The leader-trailer tape is provided thereon with a pressure-sensitive or heat-sensitive adhesive layer, so that the leader-trailer tape may be joined directly to the magnetic tape by heating or pressurizing while overlapping the tape body. Thus, the handling of the leader-trailer tape and the joining between the leader-trailer tape and the tape body may be facilitated without using any splicing tape and without causing any trouble such as sticking of the adhesive to a cutter.
