Abstract:
A steering system for the front and rear wheels of an automotive vehicle comprises a front wheel steering mechanism having an output shaft, a rear wheel steering mechanism having an input shaft coupled to the output shaft, an output member for steering the rear wheels, and a motion converting mechanism for converting rotation of the input shaft to movement of the output member, a vehicle speed sensor, and a control unit connected to the vehicle speed sensor for controlling operation of the motion converting mechanism dependent on the vehicle speed detected by the vehicle speed sensor. The motion converting mechanism comprises a shaft angularly movable by the input shaft, the shaft having an arm extending radially from one end thereof, a guide mounted on the output member and extending in a vertical direction transverse to an axis of the output member, a slide assembly disposed between and interconnecting the arm and the guide, and a drive device controlled by the control unit for moving the slide assembly along the guide. The drive device includes a gear mechanism connected with said slide assembly and a pair of motors coupled to the gear mechanism for driving the same, the pair of motors being driven in association with each other.
Abstract:
A steering assembly for a motor vehicle includes a trailing arm pivotally supported on a pivot shaft extending substantially transversely of the motor vehicle and rotatably supporting a wheel at a rear end thereof, at least three links each having one end pivotally coupled to said trailing arm and extending substantially transversely of the motor vehicle, and a steering gear box for steering the wheel. One of the three links, i.e., the first link, has an opposite end operatively coupled to said steering gear box. The other two links are coupled to the trailing arm by respective joints interconnected by a straight line serving as a kingpin axis serving as a steering center of the wheel.
Abstract:
A steering system for vehicles, in which the steered angle ratio of a rear wheel (20) to a front wheel (7) is controlled to be variable in accordance with the vehicle speed.The steered angle ratio is set stepwise with respect to the vehicle speed.
Abstract:
A steering system for front and rear wheels of a motor vehicle wherein the steering ratio of the rear wheels to the front wheels is variable dependent on the speed of the motor vehicle. The steering system includes a steering wheel, front wheels, a first assembly for steering the front wheels, rear wheels, a second assembly for steering the rear wheels, and a third assembly which transmits the direction and extent of steering of the front wheels to the second assembly, a fourth assembly controls the steering ratio between the front and rear wheels in response to a signal indicative of the speed of the motor vehicle or a signal related to the speed of the motor vehicle. Each of the rear wheels has a kingpin having a central line which has an extension which is positioned rearwardly of a point where a vertical line passing through the center of an axle of the rear wheel intersects the ground on which the motor vehicle is placed. The steering system provides a facilitated compensating operation of the steering wheel by increasing a reactive force against steering which allows the driver to return the steering wheel of its own accord without excessively turning the steering wheel upon vehicle deceleration, and reducing the reactive force to allow the driver to turn the steering wheel of its own accord upon vehicle acceleration.
Abstract:
A steering system for vehicles in which the steered angle ratio of a rear wheel (20) to a front wheel (7) is controllable by a control device (31) in accordance with the vehicle speed.The steering system has a straight travelling condition detecting device (34; 37) operatively connected to the control device, so that a correction of the steered angle ratio in accordance with the vehicle speed is effected only when a straight travelling condition of the vehicle is maintained for a predetermined period of time.
Abstract:
Disclosed is an electronic device having a communication function, the device comprising: a condition detection section 11 that detects user's operating conditions in the electronic device; a controller 1 that switches an incoming call notification mode based on at least one of the operating conditions; and a notification section that performs an incoming call notification to a user according to the incoming call notification mode.
Abstract:
A communication apparatus has a plurality of interfaces serving a plurality of networks. The communication apparatus selects an interface according to electric wave reception intensity to reduce power consumption and contribute to the maintenance of reliability in communication. The communication apparatus (communication terminal apparatus, the other party's communication terminal apparatus) is used for communication in such a way that the communication apparatuses are connected to the plurality of networks wirelessly to carry out communication through each network. The communication apparatus has the plurality of interfaces (cellular interface CI, WLAN interface WI) responding to the networks. The communication apparatus also has controlling unit (power supply controlling unit) that connects any one of the interfaces to the power supply to actuate the connected interface, and that connects an interface on rest to the power supply in response to a communication state of an interface on communication to change communication connection from the interface on communication to the other interface on rest. The communication apparatus changes the interfaces while maintaining communication with the other party's communication apparatus.
Abstract:
A receiver including: a data regeneration mechanism that receives and regenerates data transmitted in units of a packet; a storage device in which received data is stored; a packet ID extraction unit that extracts a packet ID indicating a packet to be re-received; and a retransmission request unit that transmits retransmission request information, which requests retransmission of a packet to be re-received, to a transmitter. The transmitter retransmits only a packet, which is identified with a packet ID specified in the retransmission request information sent from the receiver, to the receiver. The receiver overwrites data, which is stored in the storage device, with data contained in a packet retransmitted from the transmitter. There is thus provided a recovery system for restoring data, which is preserved in the storage device, while regenerating data without stopping a motion picture irrespective of whether a lost packet is present.
Abstract:
A terminal management device manages the sharing by at the least one business entity of costs related to distributed terminal devices. In a case that a new business entity, which uses the terminal devices and provides services after the terminal devices have been distributed, the terminal management device computes and totals the differences of shared costs of each business entity, which will change in accordance with the addition thereof. Thus, by managing the changes of a plurality of business entities bearing the costs related to terminal devices, changes in the shares of the costs thereof can be adjusted easily even in a case that business entities using the terminal devices thereof and providing services change after the terminal devices have been distributed to subscribers. Therefore, the present invention facilitates the participation of a new service business entity in the provision of services using terminal devices subsequent to the terminal devices being distributed.
Abstract:
A vehicle steering apparatus includes a steering wheel, a steering angle sensor, a turning drive mechanism for changing the direction of front wheels, and an ECU for driving the turning drive mechanism in correspondence with a steering signal. The ECU has a phase advance factor part for adding a phase advance component to the steering signal and a subtracting part for applying a behavior quantity signal outputted from a vehicle behavior sensor as a feedback signal to the output signal of the phase advance factor part.
