摘要： PROBLEM TO BE SOLVED: To provide a simple-type wheel state monitoring device capable of recognizing the wheel state of an own vehicle by a simple constitution.
SOLUTION: The wheel state monitoring device is equipped with a pneumatic sensor and a transmitter on a wheel, and an ECU 22, a receiver 24, and an alarm device 26 on a body. The ECU 22 includes an identification information storage control part 28, a storage part 30, and a state determination part 32. When a state information value received by the receiver 24 is smaller than a predetermined threshold, the identification information storage control part 28 stores identification information being a set with the state information value in the storage part 30. When a count value of the same identification information among the identification information stored in the storage part 30 reaches a predetermined determination value within a predetermined period of time, the state determination part 32 determines that the wheel state of the own vehicle is abnormal having a value smaller than the threshold. When the count value of the same identification information among the identification information stored in the storage part 30 does not reach a predetermined determination value within a predetermined period of time, it is determined that there is no abnormality in the wheel state of the own vehicle.

摘要： PROBLEM TO BE SOLVED: To avoid such miss-determination that even in the case where a tire having high vehicle-speed-dependency is mounted on a part, the pneumatic pressure of the tire is abnormal. SOLUTION: A variable value (dynamic load radial deviation β) for pneumatic pressure determination for the tire is calculated from the number of pulses PFL, PFR, PRL, PRR integrated every wheel of wheels 11-14 when the specified condition is satisfied, the calculated variable value is memorized as a reference variable value, and the vehicle speed when the reference variable value is calculated is memorized as a reference vehicle speed relating to the reference variable value. When the variable value is newly calculated, the vehicle speed at a point of time is determined whether it is within the specified vehicle speed or not based on the reference vehicle speed, and when it is determined as existing within the specified vehicle speed, the pneumatic pressure of the tire is determined whether it is normal or not on the basis of the difference between the newly calculated variable value and the reference variable value relating to the reference vehicle speed.

摘要： PROBLEM TO BE SOLVED: To improve accuracy to estimate a target parameter in a tire inflation pressure estimation device that sequentially obtains base parameters to be used for estimating the target parameter (tire inflation pressure or parameter related thereto) based on a wheel speed signal which is output from a wheel speed sensor for detecting the rotating speed of a wheel (wheel with a tire), and estimate the target parameter based on a plurality of previously obtained base parameters including the last obtained one. SOLUTION: Base parameters correspond to dependant physical quantities. As a setting time T2 passes, during which those except for the tire inflation pressure are expected to change substantially, a target parameter Δ KPRO1 corresponding to a variation of the spring constant is estimated based on M sets of base parameters. Each set comprises a rim side angular velocity ωR a disturbance ω2 a belt side angular velocity (ωB, and a spiral angle θRB obtained during the latest setting time T2.

摘要： PURPOSE:To reduce an excessive energy consumption as well as to prevent the reduction of the running stability, in an automatic auxiliary steering device of a vehicle. CONSTITUTION:The width of the dead zones of the converters 31A and 31B of a proportional and differential control system 30 are regulated automatically according to the car speed. When the car speed is low relatively, the width of the dead zone is increased, and when the car speed is high relatively, the width of the dead zone is reduced. Since the width of the dead zone scope is increased in a low speed, the steering frequency of an auxiliary steering wheel is reduced, so as to reduce the emergy necessary to drive the steering of the auxiliary steering wheel. Since the width of the dead zone scope is reduced when the car speed is in a middle speed or in a high speed, the difference between an object steering angle and the actual steering angle is reduced compared to the low speed condition, and the steering position accuracy of the auxiliary steering wheel is increased, so as to obtain a high running stability.

摘要： PURPOSE:To reduce the generation of noise caused by the backlash of gears to the utmost and heighten the transmission accuracy of the angle of rotation in a rear wheel steering system. CONSTITUTION:The rotation of a motor 20 is transmitted to a relay rod 11 through planetary roller mechanism 30 forming reduction mechanism and through ball screw mechanism 40 for converting rotation into linear motion, and lateral rear wheels RW1, RW2 are steered by the axial displacement of the rod 11 according to the rotation of the motor 20. Since a sun roller, a planetary roller and a ring roller 33 forming the planetary roller mechanism 30 are respectively friction-engaged so as not to use gears, the generation of noise caused by the backlash of gears can be prevented, and the transmission accuracy of the angle of rotation can be heightened.
