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.

A chassis dynamometer for motorcycles with a combustion engine, having a mounting unit, at least one fastening unit, an operating unit, a control unit and a roller for recording the peripheral speed of a motorcycle rear wheel is disclosed. The chassis dynamometer has a flow unit a drive unit, a diffuser and an outflow unit arranged downstream of the diffuser in the direction of flow where the diffuser and outflow unit form a flow channel carrying gas in the operating state, wherein the diffuser can be driven by the drive unit, where the control unit controls the drive unit as a function of the peripheral speed of the roller in such a way that a speed of the gas emerging from the outflow unit in the operating state is substantially equal to the peripheral speed at least from a peripheral speed of 150 km/h.

This management method for an electric bicycle (10) obtained by mounting a vehicle body frame (67) and a motor (M) comprises: a measurement step (S182) for measuring, in a state in which a back wheel (78) connected to the motor (M) is being driven by the motor (M) in a first time period, a measurement value (662), which is at least one of (A) the amount of generated power or the rotation state amount of at least one of the motor (M), the back wheel (78), and a power transmission path, and (B) the state amount of a battery (2) that supplies electric power to the motor (M); and a comparison step (S183) for comparing the measurement value (662) with a threshold corresponding to the measurement value (662) in a second time period that is later than the first time period.

The invention relates to a vehicle test stand for carrying out a test run with a complete vehicle capable of banking, characterized in that a steering force module is provided on the vehicle test stand, which can be connected to a steering system of the banking-capable complete vehicle, a steering angle detection unit is provided for determining a steering angle (M) of the steering system during the test run, a detection unit is provided for detecting a position (L) of a driver relative to the banking-capable complete vehicle during the test run, a simulation unit is provided, which is designed to use the steering angle (M) and the position (L) of the driver in a simulation model in order to calculate a steering counter force (QA) acting on the steering system and counteracting a steering force (QL) exerted by the driver, and the steering force module is designed to apply the steering counter force (QA) to the steering system.
