Abstract: To characterize a behaviour of a vehicle, a subjective behavior test is conducted on a given configuration of a suspension device and a wheel disc of the vehicle to determine whether the vehicle's behaviour is acceptable. Modifications are made to the given configuration so as to sweep through pairs of values corresponding to a lateral force Fy and a lateral offset Dy of the wheel in straight-line running For each modified configuration of the suspension device and/or the wheel disc, the subjective behaviour test is conducted again. For each configuration of the suspension device and the wheel disc tested, a determination is made of a pair of values of the lateral force Fy and the lateral offset Dy of the wheel in straight-line running Areas Z of acceptable behavior of the vehicle in a plane Fy, Dy are determined.

Abstract: A steering test stand has a first steering device with a measurement unit measuring the steering device torque value and applies forces to the steering device and control unit and has a control unit connected to a computer for controlling actuators. The computer simulates static and/or dynamic properties of a motor vehicle and transmits simulated target values to the control unit. A test driver unit comprises a second steering device as a force feedback steering wheel and a connection between the test driver unit and the computer, transmits a second steering angle set on the force feedback steering wheel. A second connection between the test driver unit and computer transmits steering torque measured on the first steering device to the test unit, such that the second steering device sets a second steering torque value on the force feedback steering wheel as a function of the first value.

Abstract: This invention is for a simple, dynamic test device and its use to assess a wheeled vehicle's dynamic performance leading to a rollover including such conditions as a curb tripped rollover, a vehicle's occupant restraint performance before and during the first roll, the motion of the vehicle's occupants before and during a rollover, and the vehicle's occupant protection performance in a rollover including its roof crush resistance. It does so by carrying a vehicle over a horizontal circular path at a speed sufficient that the centrifugal force on the vehicle will cause it to roll. The device provides unique, repeatable test conditions leading to a rollover as well as during the rollover. The device can also be used to test an object by subjecting it a high level of acceleration, force, and yawing motion about orthogonal vectors.

Abstract: A steering angle sensing device for vehicle wheel alignment includes a swingable rocking arm. The rocking arm can be located in a predetermined position and slidably connected with a simple wheel alignment calibrator. When a wheel of the vehicle is steered, the wheel alignment calibrator affixed to the wheel is synchronously rotated along with the steering of the wheel. At this time, the rocking arm is driven to swing by a corresponding angle and the steering angle sensing device emits a human-perceivable signal to a calibration worker, whereby the calibration worker can real-time know the steering angle of the wheel for conveniently performing the wheel alignment process.

Abstract: A method for conducting a basic front-end wheel alignment measurement and adjustment procedure together with a routine vehicle maintenance procedure of a vehicle service shop. Vehicle front wheel turn plate assemblies, and optionally, vehicle rolling mechanisms, are incorporated into a support structure in a service area within the vehicle service shop at which the vehicle will undergo the maintenance procedures. When the vehicle is moved into the service area to undergo the maintenance procedures, basic measurements associated with the front-end wheel alignment are acquired by an associated service system, which prompts vehicle technicians to carry out a sequence of basic procedures to facilitate the acquisition of the basic measurements. Based on the results of the measurements, the service system provides the vehicle technicians with graphical guidance for performing any required adjustment to the vehicle front end wheel alignment, which may be carried out concurrent with other maintenance procedures.
