Abstract: A target parking position setting section (23) is adapted to temporarily set a target parking position (p31, p32, p33) for the vehicle for each parking mode in a predetermined stop position. A parking mode determining section (25) is adapted to determine the parking mode and the target parking position corresponding to the parking mode based on an operation of a steering wheel performed by a driver after the target parking position (p31, p32, p33) is set. A guiding section (29) is adapted to guide the vehicle (1) to the determined target parking position (P3).

Abstract: A parking assist apparatus (1) has: an identifying portion (2a) that identifies a target parking position when the vehicle is at a temporary stop position having a predetermined positional relation with the target parking position; a parking-assisting portion (2b) that assists steering operation of a driver of the vehicle based on the target parking position when parking the vehicle. For facilitating the driver to visually confirm a positional relation between a specific portion of the target parking position and the vehicle, the parking assist apparatus includes at least one of a polarizing film (8), auxiliary mirror (12), member (22,32) provided on a vehicle mirror and extending in the vehicle lateral direction, transparent portion (42) provided in a passenger-side door, adjusting device (53) that adjusts the direction of the lower edge of the vehicle mirror, irradiating device (74) that radiates a laser, optical-axis adjusting portion (83) that adjusts an optical axis of a headlight of the vehicle.

Abstract: 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).

Abstract: A wear resistance index G1 of a tire whose wear life is to be estimated is measured by the Lambourn abrasion tester. Then, friction energies in free rolling, when the tire is fitted with a toe angle, under application of a side force, under application of a braking force and under application of a driving force of the tire are measured. An expected value of the wear life T1 is calculated using the wear resistance index G1 and the friction energies thus obtained and the wear life of the tire is estimated on the basis of the expected value of the wear life T1. The wear life of a tire can be estimated accurately in a short time in accordance with the method for estimating a tire wear life of the present invention.

Abstract: A wheel suspension of a vehicle such as an automobile having a combination of an inverse A-type arm and an I-type arm for mounting a wheel supporting member such as a spindle or an axle bearing to a vehicle body, wherein the inverse A-type arm is pivotably connected at its apex end with the vehicle body and at its two foot ends with the wheel supporting member at two points thereof spaced generally in a horizontal direction, and the I-type arm is pivotably connected at its one end with the vehicle body at a point spaced from the apex end of the inverse A-type arm generally in a horizontal direction and at its another end with the wheel supporting member at a point close to one foot end of the inverse A-type arm, the connection of the I-type arm to the wheel supporting member, and the close-by point of one foot end of the inverse A-type arm being aligned along a substantially vertical straight line.

Abstract: In the suspension for mounting a wheel supporting member such as a spindle or an axle bearing for rotatably supporting a wheel to the vehicle body by a plurality of links in a manner of allowing bounding and rebounding of the wheel relative to the vehicle body, the links are so arranged that the central axes of the links intersect a common straight line on the inboard side therof when the wheel supporting member is at its neutral position between bounding and rebounding displacements thereof.

Abstract: A structure for mounting a suspension member for supporting suspension control arms to the vehicle body with high resiliency in the longitudinal direction of the vehicle but high rigidity in the lateral direction as well as in turning as viewed from a top of the vehicle or as viewed in the longitudinal direction of the vehicle, the structure including substantially cylindrical elastic bushes disposed between the suspension member and the vehicle body to extend in the longitudinal direction of the vehicle and assist links restricting lateral shifting of longitudinal end portions of the suspension member relative to the vehicle body.

Abstract: A rear suspension of a vehicle such as an automobile having a plurality of links pivotably connected between the vehicle body and a wheel supporting member to transmit driving and braking forces therebetween while allowing bounding and rebounding movement of the wheel supporting member relative to the vehicle body, wherein the links are arranged to specify a first trace of movement of a center of rotation of the wheel and a second trace of movement of a momentary ground contact point on the wheel according to bounding and rebounding of the wheel so that, as seen in a side view of the vehicle, the point of intersection between a normal line drawn to the first trace of movement and a normal line drawn to the second trace of movement shifts from its standard position corresponding no bounding and no rebounding of the wheel forward and upward along with bounding of the wheel and rearward and downward along with rebounding of the wheel.
