摘要： PROBLEM TO BE SOLVED: To quickly determine whether or not an air pressure is normally returned after it is determined that the air pressure of a tire is abnormal in a vehicle. SOLUTION: When it is determined that the air pressure of the tire is abnormal ("abnormal determination" is varied from "0" to "1"), regarding a resonance frequency f of vibration of the tire obtained thereafter and a dynamic load radius reflection value α, it is determined whether or not the previously determined returning determination condition holds. When it holds, it is determined that the air pressure of the tire is returned to the normal state ("returning determination (relative determination)" is varied from "0" to "1"). The returning determination condition holds when respective increase amounts from when it is determined that the air pressure of the tire is abnormal become increase degrees Δf, Δα or more regarding both the resonance frequency f and the dynamic load radius reflection value α.

摘要： PROBLEM TO BE SOLVED: To precisely estimate tire pneumatic pressure regardless of type of an environmental factor affecting the estimating precision of the tire pneumatic pressure following each estimation rule by effectively using a plurality of estimation rules for estimating the vehicular tire pneumatic pressure.
SOLUTION: A resonance frequency estimated value and a dynamic load radius are respectively estimated from the wheel speed detected by each wheel speed sensor for each wheel and following two estimation rules. When a predetermined correlation exists between the two estimated values (S31 and S32) with regards to the tire pneumatic pressure of the same wheel or the same wheel group, the tire pneumatic pressure is judged following at least one of the two predetermined judgement rules corresponding to the two estimation rules (S33 or S35).

摘要： PROBLEM TO BE SOLVED: To improve reliability of a judgement result of existence of tire abnormality by properly considering a tire load which is a parameter to influence upon the reliability of the judgement result of existence of tire abnormality. SOLUTION: This device to judge existence of tire abnormality judges whether a tire is abnormal or not by comparing tire pressure which is pneumatic pressure of the tire and a standard value with each other and carries out this comparison in accordance with a load of the tire. The standard value is previously set to continuously or gradually increase in accordance with increase of the load of the tire. Materially, the standard value is constituted as combination of tire load response standard tire pressure previously set to increase in accordance with the increase of the load of the tire and tire load non-response standard tire pressure previously set so as not to change in accordance with a change of the load of the tire.

摘要： PURPOSE:To improve riding comfort of a vehicle and steering stability by suitably controlling the attitude change of a vehicle body even in traveling on the traveling road having the grade. CONSTITUTION:A vehicle speed sensor 21 detects the vehicle speed. A steering angle sensor 22 detects the steering wheel steering angle, and a differentiator 22a calculates the steering angle speed by differentiating the steering wheel steering angle. A grade sensor 23 detects the grade of the traveling road. A microcomputer 24 switches the damping characteristics of shock absorbers 10A to 10D, set to the base stage numbers in the normal state to the hard side for the specific holding time when the steering angle speed exceeds the threshold to be determined by the vehicle state. Moreover, the microcomputer 24 changes the control state of the damping characteristics of the shock absorbers 10A to 10D, such as the base stage number, the degree of the switching stage number to the steering angle speed, and the holding time according to the slope of the traveling road.

摘要： PURPOSE:To instantaneously determine a regeneration timing of a filter and thereby efficiently carry out regeneration, by operating an ignition mechanism for burning a particulate deposited on the filter according to a result of detection of an engine operating condition. CONSTITUTION:A particulate collector 20 includes a filter 23 in a main passage 22, and also includes an electric heater 24 at an inlet of the filter 23. The electric heater 24 is controlled by an ECU 40 to burn a particulate deposited on the filter 23 by heat generation. The ECU 40 inputs signals from various sensors for detecting an engine operating condition, e.g., a vehicle speed signal from a vehicle speed sensor 51. When a vehicle speed is greater than a predetermined value, the ECU 40 instantaneously determines that a regenerable timing of the filter 23 has reached, and immediately start regeneration, thus efficiently carrying out the regeneration of the filter 23.

摘要： PURPOSE:To facilitate the speed increase operation of a set vehicle speed by providing means for increasing a vehicle speed in accordance with the operation of an accelerator pedal and performing a constant speed traveling when the operation of the accelerator pedal is released during increasing the speed. CONSTITUTION:A main switch 42 is turned on during traveling and set switch 43 is turned on or off when a desired vehicle speed is achieved, then the vehicle speed at that time point is stored as a set vehicle speed. Thereafter, an actuator 10 is operated so as to maintain the set vehicle speed and the opening of a throttle valve 20 is controlled to perform a constant speed traveling. When the opening of the throttle valve 20 is increased through the operation of an accelerator pedal and the vehicle speed is increased to a desired level, the operation of the accelerator pedal is released, thereby an idle switch 51 is turned on and the speed increase operation to the set level is completed. In such a manner, the speed increase operation can be performed only through an accelerator pedal.
