    摘要： A lane-keep control system includes a traveling condition detector and a controller. The controller includes a steering intention detecting section that detects whether a driver has an intention to steer a vehicle, a first steering torque control section that controls, when the driver has no intention to steer the vehicle, a steering torque according to the traveling condition so that the vehicle keeps a predetermined position between lane markings of a lane, and a second steering torque control section that controls, when the driver has an intention to steer the vehicle, the steering torque according to the traveling condition so that a steering operation of the driver is readily reflected on steering of the vehicle. A lane-keep control method is also provided.

    摘要： The present invention provides a method for estimating a tire wear life which enables estimation of the tire wear life accurately in a short time. In this method, a rubber index Gi of a rubber test piece which is made of the same material as the material used in the tire tread portion of the tire whose tire wear life is to be estimated is measured using an abrasion tester which can be operated under a slip ratio of about 0.5 to 5% (step 100). Then, friction energies of the tire in free rolling, in a state in which the tire is provided with a toe angle, in a state in which a side force is applied to the tire, in a state in which a driving force is applied to the tire and in a state in which a braking force is applied to the tire are measured (step 102), respectively. An expected value of the tire wear life T1 is calculated from the rubber index Gi and the friction energies obtained above (step 104). The tire wear life is estimated from the expected value of the tire wear life T1 thus obtained (step 106).
