Title: Device for detecting air pressure drop of tire
Inventor: KIN KEIYU
IPC: B60C23/06
Filed: 2003-06-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide an air pressure drop detector for a tire which specifies a wheel of which the air pressure is dropped, using only wheel speed sensors, even under a traveling condition.  <P>SOLUTION: When a front right wheel speed VFR, a front left wheel speed VFL, a rear right wheel speed VRR and a rear left wheel speed VRL are input into the air pressure drop detector 1, a rectilinear travel determining parameter computing part 2 computes a front wheel yaw rate and a rear wheel yaw rate, based on data therein to determine rectilinear travel. A weighting calculation part 3 calculates a weight of which the contribution rate gets high in a rectilinear condition, in response to a degree of the determination of the rectilinear travel. A tire diameter ratio calculating part 4 calculates a tire diameter ratio, based on a deviation between a difference between front left and right wheel speeds and a difference between rear left and right wheel speeds, and based on a vehicular body speed and the weight. An air pressure drop detecting part 7 specifies the wheel of which the air pressure is dropped, based on the determination of positive and negative in the tire diameter ratio, and based on a level difference between the difference between the front left and right wheel speeds, and the difference between the rear left and right wheel speeds, when the tire diameter ratio is higher than a prescribed threshold value.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: G09F9/00
Filed: 2003-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate the misoperation of a switch by enabling an operator to recognize a processing state of the switch operation.  <P>SOLUTION: Every time detecting that a switch is turned on and, thereafter, is turned off before a prescribed time, a display of an LCD display indicator is cyclicly switched in a fundamental mode. When the duration of switch-on exceeds a prescribed time, which is detected by the display indicator, the display is switched to a display of a different mode. Further, also in the display of the different mode just as the display in the fundamental mode, when the duration of switch-on is the prescribed time or less, the display is cyclicly switched within the different mode. When detecting the duration of switch-on exceeding the prescribed time, which is detected by the display indicator, the display restores the fundamental mode and repeats the same operation. The display apparatus is constituted so as to display the duration of switch-on, as soon as the switch is turned on, and allow the operator to recognize a processing state of the switch operation.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
