    摘要： A steer angle control system for a controlled vehicle comprises sensors for sensing the steering wheel angle and the vehicle speed of the controlled vehicle, a processor such as a microcomputer, and an actuator for steering the front and/or rear wheels of the controlled vehicle in response to a control signal produced by the processor. The processor includes a reference behavior determining section for determining the value of a reference output motion variable corresponding to the sensed steering wheel angle and vehicle speed by solving a reference mathematical model representing desired vehicle motion characteristics, a vehicle behavior monitoring section for determining a value of the plant output motion variable which is a linear combination of a yawing motion variable, such as a yaw rate of the controlled vehicle, and a side translational motion variable, such as a lateral acceleration of the controlled vehicle, and a controller section for producing the control signal representing a target steer angle so as to reduce an error between the reference variable and the plant variable.

    摘要： A system for estimating the state of a controlled vehicle's motion has a steering wheel angle sensor, a vehicle speed sensor, a sensor for sensing a first motion variable such as a yaw rate, a sensor for sensing a second motion variable such as a yaw acceleration, and a processing unit such as a microcomputer. In accordance with the sensor output signals, the processing unit produces a condition signal which is in a first signal state when the unit determines that the vehicle is in a steady-state turning motion, and in a second signal state when the unit determines that the vehicle is in a transient state turning motion. The processing unit determines estimated values of the first and second motion variables corresponding to the steering wheel angle and vehicle speed by solving a first predetermined mathematical vehicle model, and further determines an estimated value of a third motion variable such as slip angle or steer angle by solving a second mathematical vehicle model which may be identical to or different from the first model. The processing unit adjusts a value of a vehicle characterizing parameter such as a cornering power of the second model in accordance with the result of comparison between the sensed and estimated values of the first motion variable when the condition signal is in the first state, and in accordance with the result of comparison between the sensed and estimated value of the second motion variable when the condition signal is in the second state.

    摘要： A system and method for controlling a steering reaction force in which at least one of motion state variables of a vehicle is estimated when a steering wheel of the vehicle is operated on the basis of a vehicle model which represents a mathematical model of the vehicle having a desired performance of motion, a target value of the steering reaction force imposed on a steering wheel is determined on the basis of the estimated value of the motion state variable, and the steering reaction force imposed on the steering wheel is generated so as to become substantially equal to the target value. The steering reaction force control system achieves the generation of the steering reaction force on the steering wheel on the basis of a vehicle turning motion information as motion state variables such as a lateral acceleration of the vehicle and/or yaw rate of the vehicle.

    摘要： A motor controlling apparatus includes a first target torque value calculator, a frequency detector, a second target torque value calculator, a torque command value calculator, a torque limiter, and a controller. The first target torque value calculator calculates a first target torque value, which is a target value of an output torque of a motor. The frequency detector detects a motor rotational frequency. The second target torque value calculator calculates a second target torque value based on the rotational frequency. The torque command value calculator mathematically combines (e.g., adds) the first and target torque values to calculate a torque command value. The torque limiter sets the signs of the first target torque value and the torque command value to be equal to limit the torque command value according to the first target torque value. The controller controls the motor based on the limited torque command value.

    摘要： According to one embodiment, a video display apparatus includes a display module, a light source device, a video signal input module, a virtual illumination value calculator, a light source illumination value calculator, and a light source controller. The light source device is divided into light source areas in a honeycomb shape and provided with light sources to light up the light source areas. The virtual illumination value calculator calculates an area illumination value indicating the brightness of light source areas to light up based on a video signal received by the video signal input module. The light source illumination value calculator calculates a light source illumination value to light up the light sources based on the area illumination value. The light source controller lights up the light sources synchronously with the video signal being displayed on the display module based on the light source illumination value.
