A wheel system adapted for use with a guided soft target (GST) is disclosed. The GST includes a soft body that is removably attachable to a dynamic motion element (DME). The wheel system has an axle connected to the soft body and a tire body rotatably connected to the axle. The tire body has an outer surface concentric with and encircling the axle with a ground-contacting tire ridge extending from and encircling the outer surface. The ridge is constructed to contact the ground when the soft body is attached to a DME. The ridge is comprised of a ridge material and has a ridge width, both of which are selected to (1) permit the tire body to slide in a direction parallel to the axle when the tire body is subjected to a lateral force; and (2) rotate the tire body as the DME moves.

A servo-controlled vehicle-supporting apparatus maintaining an unrestrained and freely self-propelled vehicle longitudinally stationary thereon. When employed inside a wind tunnel, the power transferred through groundward contact with the vehicle wheels can be directly measured, thereby indicating the propulsive power required to overcome total drag forces on a vehicle as if driving on a roadway.

A target vehicle, for example a two-wheeled vehicle, for mounting onto an ADAS (Advanced Driver Assistance System) testing platform is provided. The target vehicle comprises one or more sensors and an actuation assembly comprising an actuator. The sensors are arranged to measure a parameter relating to the dynamics of the target vehicle and may for example comprise accelerometers. The actuation assembly adjusts the tilt of the target vehicle in dependence on the output of the sensor(s), for example by means of a control unit. The tilting of the vehicle during cornering may thus be simulated. The measuring of such a parameter and the adjusting of the tilt may be conducted remotely from the testing platform. The sensor(s), control unit and actuator assembly may be self-contained within the target vehicle. A method of modeling a VRU (Vulnerable Road User) for ADAS testing is also provided.

A dynamometer includes a dynamometer chassis configured to support a vehicle thereon. A roller load test unit is mounted in a load supporting surface of the dynamometer chassis, and a chassis to chassis load measurement device is attached between the dynamometer chassis and a chassis of the vehicle positioned on the dynamometer chassis. A load sensing mechanism is attached within the chassis to chassis load measurement device between the dynamometer chassis and the chassis of the vehicle supported on the dynamometer chassis such that a longitudinal axis of the vehicle extends therethrough, and the load sensing mechanism is configured to measure force in the longitudinal direction of the vehicle.

The present invention discloses a climbing test bench for scooters, comprising a middle bridge arranged horizontally and above the ground and a first skew bridge and a second skew bridge which are arranged at both ends of the middle bridge; an upper end of the first skew bridge is hinged with one end of the middle bridge, an upper end of the second skew bridge is hinged with the other end of the middle bridge, a lower end of the first skew bridge and a lower end of the second skew bridge are in contact with the ground, respectively; and a lifting device is arranged below the middle bridge, and the lifting device may drive the middle bridge to rise and fall so that the first skew bridge and the second skew bridge form different tilt angles. Due to light weight of a scooter, it is not desired to provide a truss-frame structure. The arrangement of a lifting device can ensure the stability of the present invention.

An apparatus for repetitive use in automotive testing includes a body. The body includes a torso and a pair of legs. Each leg includes an upper portion and a lower portion pivotably connected to each other. An upper drive pivotably drives the upper portion of each of the pair of legs about a first pivot point disposed on a bottom portion of the torso. A lower drive pivotably drives the upper portion with respect to a corresponding lower portion of the leg. The upper drive and lower drive working in concert to articulate the upper and lower portions of the leg to replicate a pedaling motion.

This invention improves the precision and reliability with which rolling resistance can be measured. This rolling-resistance testing method includes a rolling-resistance measurement stage and a determination stage. In the rolling-resistance measurement stage, a component force meter is used to measure the tangential axial force that occurs in a tire axle when the tire is rotated under load. In the determination stage, the axial force is measured in a no-load stopped state in which the tire has been separated from a drum, said axial force is compared to a threshold, and if the axial force is greater than said threshold, a determination that an anomaly has occurred in the test is made.

A method for determining a transverse gradient of a road surface, on which a two-wheeler travels, the two-wheeler having at least one wheel, whose rolling circumference changes as a function of an inclination of the two-wheeler relative to the road surface, an inclination of the two-wheeler relative to the road surface being determined from a variable, which depends on the rolling circumference of the at least one wheel, and the transverse gradient of the road surface being determined from the tilt of the two-wheeler and the inclination relative to the road surface. A corresponding device and a computer program product are also described.
