Abstract: A surface adaptation method suitable for a vehicle includes evaluating a plurality of longitudinal forces with respect to a plurality of sampling points, evaluating a plurality of wheel slips with respect to the plurality of sampling points, determining a maximum longitudinal force from the plurality of longitudinal forces, and determining a wheel slip threshold from the plurality of wheel slips. The wheel slip threshold corresponds to the maximum longitudinal force.

Abstract: A method for tire force reserve estimation is applicable to a vehicle. In the method, vehicle motion information including the longitudinal acceleration, the lateral acceleration, the change of the tire rotation angle at different times, the change of the yaw at different times, the steering angle of the steering tires, etc. is continuously detected, for estimating the current normal force, the current longitudinal force and the current lateral force of each of the tires. Finally, the current normal force, the current longitudinal force, the current lateral force and the coefficient of friction of the road relative to the tires are applied to estimate the longitudinal tire force reserve and the lateral tire force reserve.

Abstract: An air-fuel parameter control system includes an injector, an air-fuel parameter sensor, a fuel film parameter calculation module, an air-fuel parameter prediction module and a fuel injection calibration module. The injector injects fuel into an intake manifold. The air-fuel parameter sensor detects a detected air-fuel parameter in an exhaust pipe. The fuel film parameter calculation module calculates a fuel film parameter relating to a fuel film accumulated the intake manifold based on the detected air-fuel parameter, an amount of the injected fuel and an amount of air flowing into the engine. The air-fuel parameter prediction module predicts a predicted air-fuel parameter based on the detected air-fuel parameter and the fuel film parameter. The fuel injection calibration module calibrates the amount of the injected fuel based on a difference between a reference air-fuel parameter and the predicted air-fuel parameter.

Abstract: A recursive route planning method for a electric vehicle, the method comprising steps of: inputting a status condition, wherein the status condition has at least one starting point and at least one destination, mileages for remaining electric power and a route distance between the starting point and destination; searching all recharge stations between the starting point and destination covering the latitude and longitude; calculating distance between each recharge station to the starting point and the destination; removing recharge stations that do not meet a search condition; integrating a list of recharge stations and planning at least one optimum route for the electric vehicle; and executing the steps above when any status condition changes to retrieve a new driving route.

Abstract: This specification discloses a driving safety auxiliary network administration system and the method thereof. Vehicles in motion communicate with each other about their geographical locations and current moving states within a communication range. At least one of the vehicles in the communication range becomes the router of several other vehicles that are at dead corners of wireless communications. The router is responsible for transferring vehicle state signals of those vehicles out of direct communications between them. Therefore, all the vehicles in the communication range are not blocked by terrains, buildings or other vehicles. All of them are taken into account to assess and find possible dangerous vehicles. This technique can effectively solve the problem of dead corners in driving safety auxiliary network communications. Highly important packets can be immediately and reliably transmitted to the corresponding vehicles, providing efficient warnings.

Abstract: A method for estimating crank angles and rotation speeds of an engine, having a signal processing unit to generate a dynamic sampling signal based on the tooth number signal of the crank detected by a crank angle sensor, an estimation unit designed by a discrete kinematic model and containing an estimator and a feedback gain matrix to read the dynamic sampling signal, and a crank rotation stroke discriminator allowing the signal processing unit to calculate a more precise crank dynamic sampling signal, so as to preclude external noises to interfering control of the engine.
