tires and vehicles -凯发k8网页登录

simple and complex tires, vehicle bodies

blocks in the simscape™ driveline™ tires and vehicles library allow you to test the response of your driveline model under various and variable environmental conditions. you can also add fidelity to your model by specifying properties such as compliance, inertia, and rolling resistance for the tires and center of gravity and frontal area for the vehicle body.

featured examples

vehicle with dual clutch transmission

a vehicle with a five-speed automatic dual-clutch transmission. the transmission controller converts the pedal deflection into a demanded torque. this demanded torque is then passed to the engine management. the pedal deflection and the vehicle speed are also used by the transmission controller to determine when the gear shifts should occur. gear shifts are implemented via the two clutches, one clutch pressure being ramped up as the other clutch pressure is ramped down. gear pre-selection via dog clutches ensures that the correct gear is fully selected before the on-going clutch is enabled.
