The disclosure discloses a system and method for predicting a vibration of a bicycle when being rode on a road. The method first uses a pressure film to obtain a contact interface between a road and a bicycle tire, and then, based on the contact interface, a unit bearing area (B) and an average stress peak distance (Sp) are calculated. Next, taking the above parameters as variables, a predicted vibration value (P) is calculated based on calculation formulas provided by the present disclosure. Finally, the predicted vibration value Pis compared with a comfort-level threshold perceived by a cyclist of the present disclosure, which can quickly and effectively grade and predict a comfort level when riding a bicycle on a section of an asphalt road.

System and method for predicting vibration of bicycle when being rode on road

Provided is an intelligent safe vehicle speed measurement method and an system capable of considering a state of a road surface, including: a laser scanning unit configured to obtain road surface textures and simulate contact under different vehicle loads and tire patterns; a wireless communication unit configured to obtain the model, load and tire information of incoming vehicles, offer a best-matching braking distance by search through database; a skid resistance prediction unit configured to obtain environmental parameters to correct the obtained best-matching braking distance, and offer a safe speed for incoming vehicles; and a warning reminder unit configured to broadcast the safe running speed to incoming vehicles. This system communicates between the vehicle and road, obtains the information from incoming vehicles in real time, and broadcasts the safe speed to incoming vehicles, ensuring the safety of the incoming vehicle during running.

Intelligent safe vehicle speed measurement method and system capable of considering state of road surface

Embodiments disclosed herein provide various aspects that would allow for Vehicle to Everything (V2X) or peer-to-peer (P2P) or sidelink (SL) communications. In an embodiment, a communication device may include: a memory for storing computer-readable instructions; and processing circuitry, configured to process the instructions stored in the memory to: obtain a first path loss between the communication device and a base station, wherein the communication device is coupled to the base station; calculate a second path loss based on one or more sidelink reference signal received power (S-RSRP) indicators received by the communication device, wherein the S-RSRP indicators are received from one or more communication devices within a communication range of the communication device; and determine a transmit (Tx) power of the communication device based on the first path loss and the second path loss.
