  • Publication number: 20240084753
    Abstract: A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.

  • Patent number: 6374890
    Abstract: The belt of a pneumatic tire is a laminate of a circumferential belt layer and an inclined belt layer, the circumferential belt layer comprising a plurality of reinforcing elements arranged substantially in parallel with the equatorial plane of the tire and coated with rubber, and the inclined belt layer comprising a plurality of reinforcing elements inclined with respect to the equatorial plane of the tire and coated with rubber, wherein at least in the coating rubber of the circumferential belt layer and the coating rubber of the inclined belt layer adjoining each other, the modulus of elasticity of the coating rubber of the circumferential belt layer is lower than that of the coating rubber of the inclined belt layer. The pneumatic tire of the invention avoids the disadvantage generated by addition of a circumferential belt layer while strengthening the circumferential rigidity by the circumferential belt layer.
