摘要： An apparatus for testing the brakes, wheel alignment, suspension, transmission, and engine of motorized wheeled vehicles, includes a dynamometer for self-calibration. A platform supports a road vehicle to be tested. Two or four pairs of short high-inertia rollers are revolvably supported adjacent to the platform, and positioned to individually support either the front wheels or the back wheels of the vehicle. The rollers are drivable by a stationary vehicle resting thereon, each pair of high-inertia rollers supporting one vehicle wheel. A floating roller contacts the wheel to detect side forces. Sensors are connected to the rollers and a computer for data processing, display and recording is connected to the sensors. Speed of the rollers is monitored by an encoder having a resolution of at least 1000 pulses/sec. A preferred embodiment of the apparatus includes electric motors which can be connected to drive the rollers.

摘要： A dynamometer includes a pair of vehicle wheel-engaging rolls coupled through a clutch to a passive power absorption unit which includes a flywheel and an eddy current brake. A lift between the rolls can raise the vehicle wheels out of engagement with the rolls without braking the rolls The lift cooperates with a frame for partially covering and protecting the access one of the vehicle rolls so that, when the lift is raised the vehicle can be driven off the dynamometer substantially without contact of the vehicle wheels with the access roll. The dynamometer is calibrated by using the vehicle wheels to accelerate and decelerate the rolls, with deceleration activating the clutch to decouple the flywheel, which is then used for a coast-down test.

摘要： An apparatus for testing an anti-lock brake system has rolls and device for detecting rotational changes of the rolls. The test is performed by running a vehicle having mounted thereon the anti-lock brake system while wheels of the vehicle are placed on the rolls, actuating the anti-lock brake system when a predetermined speed has been attained, and judging operating conditions of the anti-lock brake system from rotational changes of the rolls at the time of braking. In the apparatus, the friction coefficient of each of the rolls is set to such a value that a frictional force to act between each of the rolls and each of the wheels at the time of braking exceeds an inertia force of each of the rolls. Also the inertia weight of each of the rolls is set to such a value that deceleration of each of the wheels at the time of braking can be increased to a predetermined level which is required to start an anti-lock control and that each of the wheels does not stop before the completion of a first braking pressure reduction by the anti-lock control.

摘要： A chassis dynamometer includes at least one roll for engaging the driven wheel of a motor vehicle and a power supplying and/or absorbing unit ("PAU") coupled to the roll. Speed and force sensors are also coupled to the roll for providing signals representative of the roll speed and force supplied to or received from the roll, respectively. Vehicle inertia, road load and parasitic loss signals, representative of the vehicle inertia, the vehicle road load and dynamometer parasitic losses, respectively, are also provided. A processing unit, such as a computer, calculates a velocity error signal based on the above signals, representative of the difference between the desired and actual speed of the vehicle. The processing unit further generates a feed-forward signal in response to the speed and inertia signals, representative of at least a portion, and preferably one hundred percent, of the inertial force signal to be simulated by the PAU. A power controller in response to the feed-forward signal and the velocity error signal controls the PAU.

摘要： A method of checking the functioning of a driving wheel slip control system installed in a vehicle. Driving wheels are placed on support rollers and rotatably supported thereby. The driving wheels are driven by the engine. False signals indicative of tentative rotational speeds of trailing wheels are supplied to an ECU which in turn outputs a control signal for controlling the engine. Predetermined monitoring signals including at least the control signal output from the ECU are taken out from the driving wheel slip control system. It is determined whether the predetermined monitoring signals show values falling within respective predetermined allowable ranges. Further, a steering handle of the vehicle may be turned at the same time of rotation of the driving wheels, the steering angle of which is detected by a steering angle sensor. Further, instead of using the false signals, the trailing wheels may be placed on second support rollers for rotatably supporting the trailing wheels thereby. The second support rollers are capable of rotatively driving the trailing wheels.

摘要： A method and apparatus is disclosed for dynamically testing the operation of a vehicle anti-skid brake system of the kind which has first and second sensors associated with first and second vehicle wheels and which operates, when the brakes are being applied by the vehicle to release brake force to both wheels when either sensor senses imminent lock-up of its respective wheel. The method includes the steps of engaging the peripheries of both wheels with the peripheries of first and second motor-driven rolls, driving the rolls up to a high peripheral speed, applying and maintaining the vehicle brakes releasing the motor-drive to the first roll so that the first wheel tends to lock-up thereby actuating the anti-skid system, reapplying the motor drive to the first roll, releasing the motor drive to the second roll so that the second wheel tends to lock-up thereby actuating the anti-skid system, and generating signals in response to the actuation of the anti-skid system by either sensor.

摘要： A method for dynamically testing the operation of a vehicle anti-skid brake system and for making a record thereof includes engaging a wheel of the vehicle with a rapidly rotating roller or the like and accurately measuring and recording changes in an appropriate operating characteristic of the wheel while the vehicle brakes are being fully applied with sufficient power to rapidly slow the roller to essentially zero rpm and simultaneously to cause the anti-skid system, if operating properly, to rapidly release and reapply brake force in a manner to cause the wheel speed to decrease in stepwise fashion. The rotating roller slips relative to the vehicle wheel during application of brake force so that the wheel will be accelerated by the roll during release of brake force.
