摘要： A system for controlling the steering angle of the rear steerable wheels of a vehicle senses the front wheel steering angle, the vehicle speed and a manually selected mode signal for a new mode of two driving modes. A microcomputer containing models for the two modes determines a target yaw rate for the selected mode from which is calculated a target rear wheel steering angle to control rear wheel steering. However, the system is prevented from calculating a steering angle for the new mode when it would cause an unsafe abrupt change in vehicle behavior as when the rear wheel steering angle is not nearly zero which is equivalent to the sensed front steering angle, the target yaw rate and the lateral acceleration all being nearly zero.

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： In a rotatable antenna unit capable of being externally rotated away from and folded in a portable wireless device, an antenna detachment mechanism is provided, the antenna detachment mechanism composed of a bearing for rotatably supporting the antenna unit on the device by inserting therein and holding a pivot axis mounted on the device and an opening formed by cutting a part of the bearing. As a result, when an excessive external force is applied to the antenna unit being in an upright position, the opening is widened and the antenna unit comes off the portable wireless device. This prevents the antenna unit from being broken.

摘要： A sensor is provided for detecting traveling speed of a vehicle, and a first deviation between the traveling speed and an estimated vehicle speed calculated beforehand is calculated. Based on the first deviation and a predetermined function, a feedback compensation output is calculated, and a second deviation between a value obtained by performing on the feedback compensation output and the aforesaid estimate vehicle speed is output as an estimated acceleration. Delay processing is performed on the estimated acceleration, and an estimated vehicle speed is updated. Noise mixed with the acceleration estimation process is eliminated, and the acceleration is thereby estimated with high precision.

摘要： A rear wheel steering angle control system for a 4WS vehicle is provided. This system includes a first circuit for deriving a locus defined by a specific point provided on the front end of the vehicle, a second circuit for deriving a locus defined by a specific point provided on the rear end of the vehicle, a third circuit for providing a target steering angle for the rear wheels so that a rear corner does not overhang outwardly during turning, and a controller for controlling an actual angle for steering the rear wheels. The third circuit determines the target steering angle so as to restrict the magnitude of offset of the rear specific point from the locus of the front specific point. The controller steers the rear wheels by the target steering angle to restrict the magnitude of overhang of the rear end of the vehicle and enables the vehicle to turn within the minimum possible turning circle.
