Patent number: 5792968Abstract: A method of an accurate detection of a spinning vehicle wheel. Observed wheel speeds are derived by measuring the speed of each wheel and the slowest speed is set as the slowest observed wheel speed. A maximum probable wheel speed is derived by multiplying the slowest observed wheel speed by the ratio of the maximum wheel speed to the slowest wheel speed for a given minimum turning radius. The maximum probable wheel speed is compared with an observed wheel speed and if the observed wheel speed is greater, the wheel is deemed to be spinning.Type: GrantFiled: December 19, 1996Date of Patent: August 11, 1998Assignee: Nisshinbo Industries Inc.Inventors: Noriyuki Takemasa, Keiji Toyoda, Wataru Ozawa, Susumu Yamada, Hiroshi Oshiro

Patent number: 5734265Abstract: A method is provided to compute the probable body speed of a vehicle equipped with a mini tire as a spare tire, specifically when the mini tire is mounted. The wheel speeds of the four wheels are measured, and if the speed does not satisfy the predetermined formula relating to the wheel base and tread of the vehicle to a wheel speed, then a probable vehicle body speed is derived by the normal method. The speed thus derived is corrected by the diameter of the mini tire to compute a new probable vehicle body speed.Type: GrantFiled: March 20, 1996Date of Patent: March 31, 1998Assignee: Nisshinbo Industries Inc.Inventors: Keiji Toyoda, Noriyuki Takemasa, Wataru Ozawa, Susumu Yamada, Hiroshi Oshiro
