摘要： An assisted steering system with vibrational function for vehicles is applied to a steering system of a vehicle. The steering system has a first steering column and a second steering column, and the assisted steering system includes a speed-adjustable steering device and an electronic control unit. The speed-adjustable steering device is connected between the first steering column and the second steering column and has a motor. The electronic control unit is electrically connected to the motor, generates a vibration driving current when receiving a warning command, combines a steering driving current with the vibration driving current to generate a motor control current, and outputs the motor control current to the motor of the speed-adjustable steering device to excite windings of the motor with the vibration driving current in generation of a vibrational effect.

摘要： A vehicle positioning method via data fusion and a system using the same are disclosed. The method is performed in a processor electrically connected to a self-driving-vehicle controller and multiple electronic systems. The method is to perform a delay correction according to a first real-time coordinate, a second real-time coordinate, real-time lane recognition data, multiple vehicle dynamic parameters, and multiple vehicle information received from the multiple electronic systems with their weigh values, to generate a fusion positioning coordinate, and to determine confidence indexes. Then, the method is to output the first real-time coordinate, the second real-time coordinate, and the real-time lane recognition data that are processed by the delay correction, the fusion positioning coordinate, and the confidence indexes to the self-driving-vehicle controller for a self-driving operation.

摘要： An automatic land following control system is provided and includes an image sensor, a steering angle sensor, an inertial measurement unit, a vehicle speed sensor and a controller. The image sensor senses a vehicle lane to generate a land data. The steering angle sensor senses a steering angle to generate a steering angle data. The IMU senses an acceleration, a yaw rate and a roll angle of the vehicle to generate an acceleration data, a yaw rate data and a roll angle data. The vehicle speed sensor senses a speed of the vehicle to generate a vehicle speed data. The controller receives a digital map data, the lane data, the steering angle data, the acceleration data, the yaw rate data, the roll angle data and the vehicle speed data to calculate a compensation angle data of the wheel.

摘要： A system and a method for active steering control with automatic torque compensation are disclosed with a processor that generates a targeted torque signal after receiving a steering assistance signal generated by an active driver assistance device, overlays the targeted torque signal on a driver's torque signal after receiving the driver's torque signal sensed by a torque sensor to generate a steering torque signal, and performs an assistance logic algorithm according to the steering torque signal. As the assistance logic algorithm is performed based on both the steering assistance signal and the driver's torque signal, the steering assistance effect provided by the system and the method will not resist against the way of driver's steering, allowing the driver to easily and stably control the vehicle.

摘要： A lane tracking method is proposed for use by an autonomous vehicle running on a lane. A future location of the autonomous vehicle that corresponds to a future time point is estimated based on a current location and a measurement result of an inertial measurement unit of the autonomous vehicle. The future location of the autonomous vehicle, and a reference lane line data and a reference past location that correspond to a reference past time point are used to estimate a future lane line data that corresponds to the future time point.
