Patent number: 4830127Abstract: 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.Type: GrantFiled: December 22, 1986Date of Patent: May 16, 1989Assignee: Nissan Motor Company, Ltd.Inventors: Ken Ito, Taketoshi Kawabe

Patent number: 4829437Abstract: A system and method for automatically controlling a vehicle speed to a desired cruising speed in which after a vehicular engine is set in an acceleration state for the vehicle through an actuator under an acceleration control of the vehicle speed in response to a command operation of an acceleration switch, the vehicular engine is set so that the vehicle speed is reduced and arrives at a set cruising speed at a time of a reset of the command operation of the acceleration switch. At this time, in the vehicle speed controlling system and method, a duration in which the vehicle speed is one abruptly reduced is calculated on the basis of a control duration for which the vehicle speed is in the acceleration state under the acceleration control so that the vehicle speed is smoothly reduced and reaches the set cruising speed.Type: GrantFiled: April 28, 1987Date of Patent: May 9, 1989Assignees: Nissan Motor Company, Ltd., Jidosha Denki Kogyo Kabushiki KaishaInventors: Kouichi Suzuki, Kyoji Kobayashi, Kiyoshi Konishi

Patent number: 4823620Abstract: In a device for measuring torsional torque applied to a fixed or revolving shaft made of a magnetic material by producing a magnetic circuit in which the flux path includes a section of the shaft and detecting a magnetostrictive change induced by the torque, the surface of said section of the shaft is formed with a series of parallel grooves and/or lands or protuberances inclining at a suitable angle with the longitudinal axis of the shaft to thereby cause magnetic flux in the surface layer of the shaft to extend approximately in the direction of tensile or compressive stress produced by the torque. It is preferred to form a first series of parallel grooves extending spirally and inclining 45.degree. with said axis in one section of the shaft and a second series of parallel and spiral grooves inclining 45.degree. with said axis and reverse to the first series of grooves in another section of the shaft to detect a difference between magnetostrictive changes in the respective sections.Type: GrantFiled: February 5, 1987Date of Patent: April 25, 1989Assignee: Nissan Motor Company, Ltd.Inventors: Shouichi Edo, Hiroyuki Aoki

Patent number: 4796911Abstract: An automotive suspension system has a roll stablizer with an adjustable torsion modulus. The torsion modulus of the stabilizer is adjusted depending upon road surface conditions and other parameters. A controller is associated with the stabilizer to adjust its torsion modulus.

Patent number: 4786843Abstract: In order to permit the simultaneous variation of the illumination of a clock and the illumination of instruments included in an instrument panel of an automotive vehicle or the like, a single illumination control device is connected with the ignition switch and a lighting control switch in a manner that when the lighting switch is on, the voltage applied to the bulbs which illuminate the clock and the instrument panel are simultaneously controlled while the tail lamp bulbs are constantly energized to their normal level when only the ignition switch is on, current is fed to the clock illumination bulb.

Patent number: 4756155Abstract: A filter traps particles in exhaust from an engine. When the degree of clogging of the filter is unacceptable, the flow of intake air into the engine is throttled to increase the temperature of exhaust from the engine and thereby to burn off the particles trapped by the filter. During throttling of the intake air flow, the pressure of the intake air may be adjusted in accordance with an engine operating condition. An arrangement for finely adjusting the degree of throttling of the intake air may be added. In cases where the exhaust is recirculated through the engine, the rate of the exhaust recirculation is reduced when the intake air flow is throttled to burn off the trapped particles.Type: GrantFiled: March 19, 1986Date of Patent: July 12, 1988Assignee: Nissan Motor Company, Ltd.Inventor: Motohiro Shinzawa

Patent number: 4670759Abstract: An automatic Loran-C signal detecting apparatus samples a received signal at a constant high sampling frequency of which the Loran-C carrier frequency is a harmonic. The polarity of the sampled signal at each sampling frequency cycle is stored in a corresponding memory cell for every two successive periods of the Loran-C signal. All of memory cells are previously loaded with a value m. A control unit determines whether the polarity of the sampled signal is positive or negative and adds +1 to the value m of the memory cell when the sampled signal is positive and adds -1 to the value m of the memory cell when the sampled signal is non-positive. After a given number of Loran-C signal cycles, the accumulated polarity totals are compared to a range around the original value m to detect which memory cells, i.e. which sampling times, coincide with Loran-C pulses. The polarity of the Loran-C pulses thus detected can then be checked to identify the sending station of each group of Loran-C pulses.Type: GrantFiled: April 18, 1984Date of Patent: June 2, 1987Assignee: Nissan Motor Company, Ltd.Inventor: Hiroshige Fukuhara
