Abstract
A vehicle consumables management system includes a consumables remaining amount calculation unit receiving vehicle data including a brake pedal input signal, an outdoor temperature, a driving distance, a wheel velocity, and a wheel speed such as a wheel RPM, and calculating a remaining amount of a tire tread based on the driving distance and the wheel speed, and/or calculating a remaining amount of a brake pad based on at least one of the brake pedal input signal and vehicle acceleration and/or deceleration information, thereby being capable of accurately detecting the remaining amount of the tire tread of the vehicle without assistance of separate inspection equipment, and accurately predicting a wear amount and a remaining amount of the brake pad of the vehicle without additional expensive equipment.
Claims6
A vehicle consumables management system comprising one or more processors configured to:
- receive vehicle data including a driving distance, a wheel pulse signal, tire pressure and weight of a vehicle;
- calculate a wheel speed from the wheel pulse signal and compute a wheel slip rate based on the wheel speed;
- retrieve a corrected dynamic radius from a lookup table indexed by the tire pressure and the vehicle weight;
- correct the wheel speed using the slip rate and the corrected dynamic radius;
- and
- calculate, based on the corrected wheel speed and the driving distance, a dynamic radius of a tire and a remaining amount of a tread, and when the remaining amount of the tread of the tire is below a threshold, output an alarm.
