    摘要: To accurately detect a resonance frequency of tire even in high speed range by which tire air pressure state of each wheel is known, a calculation processing unit to which detection signals of wheel speed and resonance frequencies of tire are inputted calculates a timewise change amount of a wheel speed deviation that is a difference between wheel speed ratios of front and rear wheels. Then, it makes corrections to remove the influence of timewise change amounts of resonance frequencies of front wheels from timewise change amounts of wheel speed deviations based on a relationship between the resonance frequency and the wheel speed deviation when air pressure of the tire is changed. The unit then converts the corrected timewise change amount of the rotational state into the timewise change amount of the resonance frequencies of the rear wheels based on the above-described relationship and the resonance frequencies of the rear wheels and the timewise change amounts of the resonance frequencies of the rear wheels which have been accurately detected before the vehicle speed exceeds an upper limit value.

    摘要: A straight running state is accurately determined using only wheel speed data in any running state. Based upon right and left wheel speed values calculated by a wheel speed calculating mechanism (13) from detection values of right and left wheel speed sensors (11, 12), a wheel speed ratio calculating mechanism (21), a distance calculating mechanism (31), and a distance ratio calculating mechanism (32) respectively calculate a right and left wheel speed ratio, an actual running distance, a linear distance, and a distance ratio of the two distances at every preset checkpoint (CP). A wheel speed ratio change amount evaluating mechanism (24) extracts CPs at times where a change amount of the wheel speed ratio is relatively small as effective CPs, and a determining mechanism (43) determines an effective CP with the smallest distance ratio from among the effective CPs as in a straight running state.

    摘要: A sensor that can rapidly and accurately detect a side collision of a vehicle. The sensor includes a fixed member in a vehicle door and a movable member that has an impact receiving part. The impact receiving part has a high rigidity outside of the fixed member. The impact receiving part also has energy absorbing parts with lower rigidity and a detection part arranged opposite to the movable member at a predetermined interval above the fixed member. When the impact receiving part receives an impact exceeding a predetermined valve, the energy absorption parts are deformed so as to move the movable member. This movement is then detected by the detection part.

    摘要: A driving assistance apparatus mounted to a vehicle is disclosed. The apparatus determines whether an amount of change in tire wheel speed of each tire wheel of the vehicle exceeds a threshold. The apparatus specifies a tire wheel crossing order, which is an order in which the tire wheels of the vehicle cross over a level difference between a road and a parking lot when the vehicle crosses over the level difference. The apparatus determines whether or not the vehicle has crossed over the level difference between the road and the parking lot, based on whether a threshold-exceeding order is identical to the specified tire wheel crossing order. The threshold-exceeding order is an order in which the amounts of change in the tire wheel speed of the respective tire wheels exceed the threshold.

    摘要: In a light chamber formed in a housing case and a lens cover placed at a front part of the housing case in a headlamp assembly, a projection lens, a shade and a light source are arranged in line from the front side of the light chamber along an optical axis of the light source. A radiating member has radiating fins of a plate shape vertically placed in the light chamber, and radiates heat energy generated by the light source to surrounding air. A slit composed of a vertical slit part and an inclined-slit part is formed in each of the radiating fins. The formation of the slit generates a change of heat capacity and a temperature difference at upper and bottom parts of each of the radiating fins. The incline-slit part is extended from the top of the vertical slit part to the upper part of the radiating fin.
