A vehicle stability control system operates by detecting a wheel speed potentially indicative of the presence of a mini-spare wheel at a wheel location of a vehicle with a wheel speed sensor and determines that a mini-spare tire is present responsive to the wheel speed remaining within a predefined band for predefined time. A threshold value that triggers action by a vehicle stability control system is adjusted to provide the mini-spare wheel with a value different than a wheel speed threshold value indicative of wheel slipping for a standard wheel.

Quick mini-spare detection

A vehicle includes a tone wheel having a plurality of encoding members spaced substantially evenly about a periphery thereof. Each tone wheel is rotates with an associated wheel. A fixed speed sensor is mounted adjacent to each tone wheel. The vehicle includes a brake system. A method determines a travel distance between adjacent encoding members. A required rolling distance of a vehicle from standstill is established. Maximum allowed interrupts per wheel is established, with an interrupt defined as each instance an encoding member passes an associated speed sensor. It is determined whether the vehicle is actually rolling from standstill. Once the vehicle is actually rolling, a number of interrupts is counted at each wheel. When the maximum allowed interrupts is counted at each wheel, the brake system is supplied with pressure increase to return the vehicle to, and hold the vehicle at, standstill prior to reaching the required rolling distance.
