摘要： An in-vehicle system and method for warning a driver of upcoming curves in a road including. In general, a vehicle positioning module determines the vehicle's position in a global positioning system and a map matching module determines the vehicle's position on a map based on the position in the global positioning system. A look ahead module looks ahead on the map for a curve, determines a candidate list of probable driving paths through the curve, and from this candidate list determines the most likely path of the vehicle around the curve. A warning module then assesses the threat the upcoming curve poses to the vehicle.

摘要： A detection method for preventing an automobile from colliding is applied to an automobile. The detection method includes the following steps: step (a): providing at least two detection devices, each detection device is used to measure a predetermined information of the automobile. A one-stage linear Kalman filter in each device is used to enhance the signal-to-noise ratio of the predetermined information. In step (b): utilizing the one-stage linear filter to receive the predetermined information and obtain a corrected information from the predetermined information after the signal-to-noise ratio is enhanced. In step (c): calculating the corrected information to obtain a component information having vector components of a first direction and a second direction. In step (d): enhancing the signal-to-noise ratio to enable the component information to be a contrast information. Accordingly, the convergence time of calculating the contrast information can be substantially reduced. The position variation of the surrounding moving objects can be accurately estimated to prevent the sudden collision in a short time.

摘要： A method and apparatus for determining likelihood of rollover of a vehicle and/or mitigating rollover of the vehicle is responsive to measured vehicle lateral acceleration and a measured one of vehicle roll rate and vehicle suspension displacements to derive estimates of roll angle and roll rate. First, preliminary, estimates of roll angle and roll rate are derived and used as pseudo-measurements in a dynamic, closed loop observer equation which represents a model of the vehicle in a first roll mode for roll angles small compared to a reference value indicating two wheel lift-off and a second roll mode for roll angles at least near a reference value indicating two wheel lift-off. The observer equation has parameters and gains with values for each mode stored as a function of roll angle index derived from measurements and pseudo-measured values. The observer equation produces second, improved values or roll angle and roll rate together indicating the likelihood of vehicle rollover. Rollover mitigating controls for brakes, active front steer, and/or active rear steer are also disclosed.

摘要： In an acceleration estimation device for estimating acceleration of a vehicle, a Karman filter for a constant speed estimates x-direction acceleration offset and z-direction acceleration offset when a motorcycle is stopped and is traveling at constant speed. An offset storage stores an x-direction acceleration offset estimated value and a z-direction acceleration offset estimated value. An offset corrector corrects an x-direction acceleration and a z-direction acceleration on the basis of the x-direction acceleration offset estimated value and the z-direction acceleration offset estimated value when the motorcycle is accelerated and decelerated. A Karman filter for acceleration/deceleration estimates the pitch angle of a vehicle body when the motorcycle is accelerated and decelerated. An acceleration corrector obtains an X-direction acceleration and a Z-direction acceleration on the basis of the estimated pitch angle. A vehicle speed operation unit integrates over time the X-direction acceleration to calculate an X-direction speed.

摘要： A system for determining accurate inertial navigation data of a vehicle while moving must compensate for the orientation differences between an upper body and a lower body of the vehicle. These orientation differences are used to increase the accuracy of the aided inertial navigation solution. An odometer on the lower body is used to reduced errors in the inertial date arising from movement between the upper and low bodies and errors in the odometer associated with vehicle pitch are reduced by sensing pitch changes with the inertial navigation data.
