Motorcycles can become unstable when operating at high speeds and at high cornering levels. For example, they can exhibit an oscillation at the rear wheel commonly known as weave. A system and method is provided which utilizes a high-fidelity computer simulation model of a 2- or 3-wheel motorcycle to predict operating states such as yaw rate, lateral acceleration and roll angle for a stable motorcycle at a given speed and steer angle. The operating state of a physical motorcycle can be measured and compared to that of the model at every instant in time to determine if the operating state of the physical motorcycle differs from that of the simulation model in such a way as to indicate loss of stability. The nature of that difference can then be used to intervene in the operation of the motorcycle independent of driver actions by application of brakes, modulating the engine torque or applying torques to urge the steering system in a corrective direction. Thus by comparing the physical response of the motorcycle to that of the computer model in an on-board controller these interventions can be applied at a time and intensity to stabilize the motorcycle and prevent a loss of control.

An all-terrain vehicle includes a frame, wheels, a vehicle cover, a power supply system a saddle assembly, a brake system, a drive assembly and a suspension system. The all-terrain vehicle is sized for children to ride, with numerous disclosed modifications in accordance with its size and riders. For instance, the saddle assembly includes a locking hook accessible from the rear of the vehicle, and in the locked state holds the main power supply down into its compartment. The brake system uses a pawl for two handed setting of the parking brake. The instrument assembly allows adjustment of the display angle of the display screen. The charger cover uses a damping block to cause the cover to hover at a selected position. The all-terrain vehicle can meet the use needs and safety requirements of all-terrain vehicles for kids, and can ensure the safety of drivers.

This invention relates to a hydraulic-type time-difference brake apparatus, which includes at least a driving device, a housing, a first pump mechanism and a second pump mechanism as main components combined together. Said driving device is provided with a first driving rod, a second driving rod, a brake starting member and a housing, one end of the first driving rod is connected to the brake starting member, and the other end is connected to the first pump mechanism, the first driving rod can push the first pump mechanism and output the first braking force to the rear wheel brake; one end of the second driving rod is connected to the brake starting member by a sliding device, and the other end is connected to the second pump mechanism, the second driving rod can push the second pump mechanism and output the second braking force to the front wheel brake. The sliding process of the sliding device can delay the time the brake starting member activates the second driving rod, so that the start time between the first driving rod and the second driving rod will have a time difference. In this way, the driver can cause the rear wheel brake and the front wheel brake to generate a time-difference brake by only one braking operation, the rear wheel brake can first generate a braking force on the rear wheel to reduce the speed of the rear wheel, then the front wheel brake will generate a larger braking force on the front wheel more than the rear wheel after a time difference to improve the safety of the vehicle.

This invention relates to a double linkage safety brake system, which includes at least a brake handle, a base, a rear wheel brake wire, a front wheel brake line, a rear wheel brake and a front wheel brake. Said brake handle is provided with a first connecting rod and a second connection rod, the driving arm of brake handle is provided with a first shaft hole and a second shaft hole, the second shaft hole is an arc-shaped elongated hole, the distance between the first shaft hole and the shaft 200 is smaller than the distance between the second shaft hole and the shaft. A first support shaft is pivoted between the first shaft hole and the first connecting rod, and the outer side of the first connecting rod is connected to said rear wheel brake wire. A second support shaft is pivoted between the second shaft slot and the second connecting rod, and the outer side of the second connecting rod is connected to the front wheel brake wire. In this way, the driver only needs to press the brake once to output a time difference braking force by the first connecting rod and the second connecting rod, and the rear wheel brake and the front wheel brake can generate a time difference braking action; furthermore, the moving arc length of the second connecting rod is greater than the moving arc length of the first connecting rod when the driving arm rotates, so the braking force generated by the second connecting rod is greater than the braking force of the first connecting rod, and the braking force of the front wheel brake is greater than the braking force of the rear wheel brake, to achieve the purpose of safe braking, and can prevent accidents caused by the driver start the front wheel brake first.
