摘要： PROBLEM TO BE SOLVED: To automatically register information corresponding to wheel identification information in vehicle-body-side device, in a wheel state acquisition device in which a wheel state is acquired by communication between a wheel-side device and the vehicle-body-side device. SOLUTION: Antennas 75, 76 for outputting trigger signals are mounted on a wheel mounting state inspection device. In a case where the wheel mounting state inspection device 14 faces a wheel, when the wheel is rotated, the wheel-side device 100 faces either of the antennas 75, 76, so that the identification information are transmitted from the wheel-side device by the trigger signals transmitted from the antennas 75, 76. The transmitted identification information are received and registered by the vehicle-body-side device 102. Thus, a worker can eliminate the need for transportation of a trigger device for each wheel and can automatically register the identification information. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To automatically determine whether the tire information is transmitted from a non-mounted tire or not when the tire information is transmitted from a plurality of tires including a mounted tire mounted on a vehicle and a non- mounted tire carried on the vehicle without being mounted on the vehicle. SOLUTION: A temperature of the mounted tire is raised with a large gradient as the vehicle traveling time passes, while the temperature variation of the non-mounted tire is small. When temperature variation quantity ΔTh in a predetermined time period shown by the temperature information included in the tire information transmitted from the tire is equal to or lower than predetermined variation quantity ΔTs, it is determined that the tire information is transmitted from the non-mounted tire.

摘要： PURPOSE:To detect a malfunction of yaw rate sensor output with a simple constitution by constituting a yaw rate detecting value or a working value so as to judge whether it is within the specified range depending on the basis of a detected front-wheel steering angle or not. CONSTITUTION:A steering angle is detected by a front-wheel steering angle sensor 61, and thereby whether the yaw rate detecting value of a yaw rate sensor 63 or the working value is within the specified range dependent on the basis of a detected front wheel steering angle or not is judged by an electric controller C. Incidentally, a yaw rate acting on a car body is a physical quantity closely rated to steering of a vehicle, while a steering wheel 14 is maintained in the state that a turning angle is large to some extent, and when the vehicle is in turning motion at a small turning radius, the yaw rate shows a large value, and a variation in this yaw rate grows larger when the steering wheel 14 is quickly turned and the vehicle is suddenly steered. Consequently, such a yaw rate that may be really produced in the car body is compared with the detected yaw rate, through which something wrong in the output of the yaw rate sensor 63 is judged.

摘要： PURPOSE:To improve the response of the rear wheel steering in a straight running condition without reducing the forward heading property in a turning steering time by setting an object steering amount reflecting the yaw rate smaller when the steering angle of the front wheels detected by a rear wheel steering control device is large, and reflecting larger when the steering angle is small. CONSTITUTION:When a rear wheel steering mechanism 1 steers the rear wheels, a yaw rate detecting device 2 detects the yaw rate generated at the car body, and an object steering amount increasing as the yaw rate increases is determined to steer the rear wheels to deny the yaw rate depending on the detected yaw rate. The rear wheel steering control device 3 makes the steering amount of the rear wheels into the determined object steering amount. In this case, the rear wheel steering control device 3 makes the yaw rate detected by the first steering amount setting device 5 reflected smaller when the steering angle of the front wheels detected by a front wheel steering angle detecting device 4 is large, and the yaw rate detected by the second steering amount setting device 6 reflected larger when that steering angle is small, to set the object steering amount.

摘要： PURPOSE:To improve stability and responsiveness of a vehicle by steering the rear wheels according to the optimum feedback gain calculated by a basic gain determined depending on the stability and responsiveness of a vehicle from the relation between slip angles of front and rear wheels and a steering angle and a vehicle state decision value showing the state of the vehicle and a driver's will. CONSTITUTION:A steering speed signal and a car velocity signal are input to vehicle state decision means II11 to decide the state of the vehicle and the present state of a driver's steering will from the above signals and output a vehicle state decision value. On the other hand, basic gain generating means II12 decides the basic gain depending on the stability and responsiveness of the vehicle. Optimum gain calculating means II13 calculates the feedback gain most suitable for the present vehicle state according to the basic gain and the vehicle state decision value to be output as the optimum gain. Steering amount calculating means 11 calculates the rear wheel steering amount by multiplying the behavior variation of a vehicle from a behavior sensor I3 by the optimum gain to be output as a control signal. Rear wheel steering actuator means III controls the rear wheels to be steered according to the control signal.

摘要： PURPOSE:To enable accurate steering of rear wheels to be attained, by calculating a car speed on the basis of a rotary speed of plural wheels while determining steering angle ratio on the basis of the calculated car speed and controlling a rear wheel steering device so that the accurate car speed can be always detected in no relation to racing of one single wheel. CONSTITUTION:A front and rear wheel steered vehicle steers rear wheels RW by controlling a rear wheel steering device 1 in accordance with a steering condition of front wheels FW and a car speed. Here a rotary speed detecting sensors 2a, 2b, which respectively detect rotary speeds of plural wheels FW, are provided, and on the basis of output signals of these sensors, the car speed is calculated by a car speed arithmetic means 3. And on the basis of the calculated car speed, a steering angle ratio determining means 4 calculates ratio (steering angle ratio) of the rear wheels RW for a steering angle of the front wheels FW. While a moderating means 5, which relaxes a change of the steering angle ratio due to a change of the calculated car speed, is provided, thus a control means 6, which outputs a control signal corresponding to the relaxed steering angle ratio to the rear wheel steering device 1, steers the rear wheels RW in accordance with the steering angle ratio.

摘要： PROBLEM TO BE SOLVED: To provide a tire pressure warning system by which safety is further improved. SOLUTION: A tire pressure warning system emits a tire pressure decrease warning, based on a relationship between tire temperature and reference tire pressure, if the tire pressure is lower than a first tire pressure warning threshold value with respect to the reference tire pressure, and after emitting the tire pressure decrease warning, terminates the tire pressure decrease warning if the tire pressure is higher than a second tire pressure warning threshold value with respect to the reference tire pressure. In this system, the first tire pressure warning threshold value is lower than the second tire pressure warning threshold value, and a difference between the first tire pressure warning threshold value and the second tire pressure warning threshold one is structured to be smaller in case that the tire temperature is higher than a predetermined temperature threshold value than in case that the tire temperature is lower than the predetermined temperature threshold value.
